Update of note. APRSICSE, when in development mode, can now import gpx files so routes of events can now been seen. Useful if the event organisers have already produced the gpx file for those using their gps devices..

(Development mode, change the line in the APRSIS32.xml, 0, change 0 to a 1. Then About in the program when restarted to download the development version.)

Gloucestershire BHF Ride 20th May

Gloucestershire Raynet have been requested to provide support to the SJA for this charity ride around the county.

The control station will be based 300m asl outside Cheltenham at 51.935183N -1.922864W, with the potential to cause significant QRM to regional Groups.

Due to the nature of the course, operation from this well-sited location may clash with other RAYNET activities on the day, and the group apologise in advance for any problems.

Intended operational frequencies are 145.225 primary, 144.675/145.200 MHz backup, with the callsign M0RGL being assigned to Control.

West Kent need a Cyclist /M!

On 22nd July West Kent Raynet will be assisting with the Dartford Half Marathon.
Last year they were able to provide a Raynet cyclist as back marker to the competitors.
He ran APRS and voice along the route and the idea was particularly liked by the organisers. We only have one person with required bicycle, level of fitness and battery panniers, and he cant make the date.
Is there someone else in the South East who could get to Dartford (with bicycle) on the 22nd that would be prepared to help out?

If you can help. please contact Colin M0NLP at colincolinco.co.uk

Are you busy on the 19th?

Nottingham Group are still looking for help on 19th May for their "Footprint Walk" duty.

Details of the event and contact details for Eddie the Group Controller can be found on the Diary pages of the RAYNET web-site.

This goes for any open WiFi system (such as the proliferation of ones in coffee shops etc.), as the devices are normally all on the same subnet and therefore visible to each other. Try running a network scanner the next time you are using one!

Always, always have your firewall enabled and lock down the usual routes that malware can get onto your machine (such as the default admin shares - used by many viruses to spread themselves).

FBI issues warning about using hotel Internet connections

Travellers are tricked into downloading malicious software after logging onto a hotel Internet connection

The FBI today (10 May 2012) warned travelers there has been an increase in malicious software infecting laptops and other devices linked to hotel Internet connections.
The FBI wasn't specific about any particular hotel chain, nor the software involved but stated: "Recent analysis from the FBI and other government agencies demonstrates that malicious actors are targeting travelers abroad through pop-up windows while they are establishing an Internet connection in their hotel rooms.
The FBI recommends that all government, private industry, and academic personnel who travel abroad take extra caution before updating software products through their hotel Internet connection. Checking the author or digital certificate of any prompted update to see if it corresponds to the software vendor may reveal an attempted attack. The FBI also recommends that travelers perform software updates on laptops immediately before traveling, and that they download software updates directly from the software vendor's website if updates are necessary while abroad."...................more info here: http://news.techworld.com/security/3356866/fbi-issues-warning-about-using-hotel-internet-connections/

MOU with BAPCO

On the 16th of April British APCO President Alan House and The Network Chairman Cathy Clark signed a Memorandum of Understanding that recognised the common objectives of both organisations in the promotion and influencing of public safety, civil contingency, information management and communications technologies.

In the MOU, RAYNET is identified as “The Network”, and in addition to the MOU, a Schedule of Agreements is included which sets out some of the ways in which both organisations will work together, including networking opportunities and invitations to attend management meetings; website content sharing; joint working and sharing of publications; and engaging The Network in regional and national events.

Operations Manager at British APCO Colin Millar, commented: ‘Chris Hampson from The Network and Peter Prater from British APCO were responsible for initiating the process following a brainstorming session two years ago. This resulted in the original draft documents which in turn led to the production of the final version as signed by British APCO and RAYNET.

‘The British APCO Executive is keen to develop the MOU concept,’ added Colin, ‘and it is anticipated that further similar agreements will be signed off at future annual events, with other like-minded voluntary sector organisations`.

Farnham Cycle Ride on 1st July

James Day M0GQC of Surrey West Group has advised that they will be providing communications for this event.

The course presents considerable challenges for communications,and the Group propose to use a well-sited talkthrough unit to provide effective communications with all their out-stations.

Previous experience on this event shows that the coverage from the TT site may cause difficulties for other groups with events over a large part of South East England.

The frequencies proposed for the operation are 144.650MHz (with 144.675 as a backup) and possibly some data transmissions on 433.750MHz, and they wish to apologise to other users of these frequencies during the event.

Further details and information can be found by contacting James, using the "HELP" link for the event entry on the diary pages of the RAYNET web site.

Isle of Man RAYNET

The next meeting of the IOMARS (Isle of Man Amateur Radio Society) takes place on Tuesday 8th May at 7.30pm in the Sea Cadet Hall (TS Manxman) Tromode Road, Douglas. The topic will be EMERGENCY COMUNICATION and RAYNET ISLE OF MAN.

The night will be devoted to this topic and the meeting has been opened up to non-members, non-license holders and anyone that may be interested in taking part in the discussion or assisting in some way in the future.

After seeing on TV, reading in the press etc about the massive build-up in force within London I think it is not a place I would like to be, they are quite clearly not thinking they are going to get one person who mat attack with a 22 air gun are they? and even thinking of bringing an Airplane down full of people on a built-up area could ruin a persons entire day I think, maybe others wont think that way.
No, I feel safer watching it on TV in my home a few miles away.

Hello Cathy,
Thank you for answering my question, it's pretty much as I thought it would be. I do hope I haven't upset you with my posts, I just come at the whole area from a different backround, with a broard perspective on matters like these, and I'm only too aware that questioning well established ideas isn't always received well.

RAYNET are taking the view, as are a number of other voluntary aid societies, that it is "business as usual" during the Olympics.

RAYNET members in and around London have been asked to assist London Red Cross with the manning of their communications suite in North London.

A number of groups throughout the UK have been asked by their local authorities to assist with the events surrounding the Olympic Torch and Paralympic Torch routes.

Hi Dave,

I'd have been more inclined to think the reason for hams, as it was aimed at amateurs, not to use radios was to avoid any chance of problems with comms.

I'd have imagined RAYNET in that area would all be ready to lend a hand locally if anything went wrong. Not too sure about renagade RAYNET operators

Hello again, yes I think one of the main reasons Raynet wont be able to attend the Olympic venue is because a radio could be used by a person to make things go bang, that is the reason Ofcom have banned radio's like our;s from the event.
We all know Radio Hams often get radios stolen that may be used by people who should not have them, so the only way of stopping a problem is not to let the radio's in side event.
I read that some repeaters have had to be turned off or power lowered also so that shows how the powers that be are concerned about too much RF about.
Cheers,
David

Hi Dave,

thanks for replying, I understand what you say, there are many levels of emergency, it's a complicated beast is LocalGov Planning. Worst case scenario running around with radios, as you say, would get you lifted or far worse. Just look at the Olympic planning, "anyone attempting to gain access to any event with radio transmitting equipment will be refused entry", out of OFCOMs mouth. So you can imagine how you'd be treated at a time of hightend sensitivity to matters of state security.....RAYNET or not.

Everything has it's place and time, but I think RAYNET could do and be so much more.

Hello Jim,

I know different areas have different levels of cooperation, it was just a comment on how as a Local Authority we treated our local RAYNET group. The working relationship that North Linc have with the County Council here seems excellent. I'm still in touch with my old Authority's Planners and doers and they still keep us (RAYNET) at arms length. They talk to them and even had an exercise testing their capabilities, which as you can imagine where noted and shut away in a draw.

I know RAYNET have forged some very strong links with other voluntary bodies, but I can't help looking at it like a Council Officer and seeing how we as an organisation can project ourselves at a higher level, and provide something that can't be missed out on. I may only be an M3 within our hobby, but with 23 years behind me within Local Government I can see many things we could as RAYNET be doing to make us invaluable to local planners.

Kind regards Terry.

The landscape isn't the same in every local authority area.

Some have excellent working relationships with their local Emergency Management teams, exercise regularly, do get called out and generally provide a professional service that is valued by the User Services in the area. The number of reported call-outs supports this, with many calls coming very early on in the emergency.

In my experience the need for RAYNET services and the associated professionalism tends to be because of specific local conditions. Some Groups on the south coast have very good working relationships with the coastguard. Others in the more mountainous / remote areas of the UK provide specialist communications where the Users struggle.

Conversely, planners in "simpler" areas don't see the need for RAYNET and pay them lip-service.

Central government certainly know about RAYNET and have regular dialogue with the organisation at a national level, but our local authority structure is so fragmented in the UK that no amount of "kicking" from Government will have much effect in some areas.

Those that have the relationship enjoy the activities it provides.

Those who don't, enjoy doing the local community events.

Hello Terry,
Just read your posting, and yes 100% on what you said, I have since living in Suffolk had 3 EPO's round to see me for a chat over a cup of coffee, and show them my station and other emergency gear I have like lighting, Rad Counters etc, all 3 were very impressed, but sadly they did get in a cold sweat when they found I was more in the picture of things than they were.
Sadly at the end of the day it makes no matter how the EPO's see ham radio user's of any sort today, it is the Home Office that wont work with them, sorry it's fact like it or not, we are not in major planning since 1999.
We can play and plan all we like, but you know Terry as I do with County planning that it is all in the hands now of H.O and Police, Fire, Ambulance service, bit of WRVS, Salvation Army, and in major events the TA would take over our streets, and anyone running around with a radio in the hand could get badly hurt.
I know as I have the plans as I would think you too have Terry?
Bye take care,
David

Yes most of the problem is that with so many months without rain the ground got hard, so the 4 weeks of heavy rain we have had has all just stood on the surface and not soaked in the ground, just a shame that the UK has no places to put all this water so it could be used rather than go to waste.

Hello everyone,

the last point made by David G7JAK is a valid one, I'm a member of RAYNET in Lincolnshire, but professionally was an Emergency Communications Officer for many years for Local Government in another part of the country. We didn't at any point encourage the assistance of local amateurs (RAYNET). We had a contact number, but in all honesty the Amateurs whos information we had wouldn't have liked how they where to help us if things became desperate. Things have changed a little over the past year or two in that area, however, being in the unique position to see both sides of the fence, I know RAYNET really has a very steep hill to climb. We may be written into many emergency plans all over the country, we can help in annual exercises and be all friendly and cosy with LocGov/Fire/Police, but, when push comes to shove, how much trust have they in us (RAYNET)? We looked at what our local RAYNET really had to offer and how they may fit into our planning, and one of the stumbling blocks where the made up phonetics that seem to be used far to often, and the ability to communicate on the same level with Fire/Police/Ambo. There where lots of other concerns, but many in RAYNET have worked very hard to fix some things. I'm a proud member of RAYNET, under used, but happy to help and bring whatever helps to the table. As a group we have great skills to offer lots of Services, we just need to keep growing, become slicker and show our amateur professionalism (not often you get the chance to use those two words together )

Well, that ran away with itself.

Kind regards Terry

Internet blackout' set for 9 July

"On 9 July this year, the internet will suddenly 'turn off' for thousands of users around the world.

Around 350,000 PC users have machines infected with an invisible, undetectable 'Trojan' computer virus called DNSChanger, which sends users of the Web to unintended - and sometimes illegal - sites.

When the FBI detected the infection they set up 'surrogate' servers to keep the infected PCs working - but it's costing so much that they intend to 'pull the plug' on 9 July. "

The temporary servers set up by the FBI were created to allow companies to remove the worm from their infected servers; those affected had 120 days to get rid of the malware.

After FBI warnings, the number of PCs infected with the Trojan has plunged - and most are in the hands of private individuals, not companies.

Of the 350,000 infected machines worldwide, 85,000 are in the U.S and 20,000 are in the UK.

Olympics 2012 and Amateur Frequencies

OFCOM have published further information on the use of the 70cm and 2Ghz Amateur allocations during the period of the Olynmpic and Paralympic Games.

Well sited amateurs are asked to assess if their transmissions are likely to be received in any of the defined Games areas, and to avoid the use of frequencies within specified areas.

In particular, they have also defined some restrictions where the use of talk-through units by RAYNET may be affected.

The full details of the statement may be found at
http://licensing.ofcom.org.u/radiocommunication-licences/amateur-radio/ar_spectrum_use/

RSGB Media Support

GB2RS News reports that the Society has developed a media pack enabling members to support Clubs in providing information to local media.

US ARES active again.

ARES members in the USA have been active again during tornados in North Texas. A seven hour storm saw 21 tornados sweep through Dallas and Fort Worth

Radio Amateur volunteers also took part in a Tsunami Exercise in Puerto Rico and the Virgin Islands. This tested sirens, emergency alerting systems, and the reporting of emergency traffic on lcoa radio.

Use of Amateur Frequencies by Olympic and Paralympic Games

"The UK communications regulator Ofcom has provided details of the areas that need to be protected from RF within the designated frequency ranges. Ofcom say the use of radio by Amateurs in the areas defined in Annexes A and B below could cause interference to Games applications; it is also possible that higher power transmissions from outside these areas could cause interference."

Consequently, to avoid the risk of interference to Games applications, Ofcom request that Amateurs do not operate within the frequency ranges identified in the areas defined in Annexes A and B, and that Amateurs ensure that any signals that could be received in these areas are negligible.

Individual Amateurs should assess if their transmission is likely to be received in the defined areas and if in any doubt please DONT operate within the frequency ranges identified.

This indicates that the specified frequency ranges should be avoided for a considerable distance outside the designated zones. Clearly a well equipped station on a good site 75 km from the edge of a zone could still put a signal into that area.

Some years back I had the 4x4 version of that van with a Perkins Phaser turbo diesel engine. That returned 20 MPG. It was ex-electricity board with a hydraulic winch etc.

I'd budget for a figure of 12 MPG for the petrol version if you are thinking about buying it.

I used mine for radio survey work with a 15m Clarke Masts SCAM mast on the back.

British Red Cross purchase six new mobile satellite command vehicles

To support its many staff and the valuable work they do, and to integrate better with the fire and rescue, police and ambulance services, the British Red Cross recently undertook a major review of its communications requirements, with a view to upgrading its mobile incident communications. As a result of this detailed process it recently introduced six new advanced command communications vehicles, which feature a range of advanced technologies, including mobile satellite broadband.

John Blake, National Emergency Communications Manager for the British Red Cross, said;

“We now have a fleet of six national communications vehicles spread geographically throughout the UK: one in northern Scotland to work with our Red Cross Fast Water Rescue Team, one in Glasgow, one in Newcastle, one in Warmley, one in Enfield serving London and another in Mitcham serving the south east. All serve a wide local area but can be deployed anywhere in the UK to support our work.”

AFAIK the issue with blowing rigs up connecting the heads is to do with not inserting the RJ11/12/45 (whichever is used on your radio!) straight and briefly cross-shorting the pins, which can fry the processor.

I have Kenwood D700's and V71's, have never isolated and not had a problem, but have heard about others who have fried their D700. I'm just very careful to insert it straight.

This is a topic of some interest to me as I have decided that I ought to properly fit at least one of my radios in the car rather than spend a number of minutes executively wiring stuff up and running the rig on the passenger seat. Posts to the appropriate Yahoo groups seem to have drawn the usual variance of opinion between those who don't see the need to isolate and do or would disconnect the remote heads with the main unit off but powered up and those who can see my point (and in one case one who has blown up a ft-8900) as to why there is a need to isolate the rig(s) (FT-857D and FT-8900R).

An e-mail to Yaesu UK brought forth the recommendation to isolate so I plan on fitting a relay along with my FT-8900 so I guess a 30amp automotive sourced relay that I've got should suffice.

Oh how I long for the old days when there was so much more space to fit rigs and I could just whip my old FT-290R out of its cradle and solve security problems with little effort.

We've used aprs.fi on a couple of recent events for organisers to see what's going on and it's been well received, so providing the Internet is still working when the proverbial hits the fan...

Consistent beacon times shorter than 10 minutes are considered "abusive" on the main RF APRS network but for short periods is fine. As is often said, it's not a tracking channel, it's for communication as APRS is far more than just locations!

We regularly have half a dozen trackers (mostly mobiles), sometimes need a digi or two for coverage if it's a bigger event.

Biggest APRS network I've set up is 15 mobiles on a 35 second beacon rate (using time-slotting), but that was on a closed system and, whilst everything was being gated to the APRS-IS network, nothing came out on RF anywhere else. Originally 6 digis also set up, but latterly 4 digis and 5 iGates on our own internal APRS-IS server.

One of the difficulties with timeslotting is that each tracker has a different implementation (or none in the case of the Kenwood & Yaesu radios), so is difficult to get a consistent setup if equipment is supplied by different people.

Jim

Most of our operations have been on 144.800. This permits us to take advantage of the MB7UEW digipeater which picks up many reports from our usual areas of operations. We have also deployed event-specific digipeaters for some events. There are are at least three iGates in our area so the majority of reports reach the IS. We make increasing use of APRS.FI in real time during the events.

We try to limit beacon intervals as a matter of good practice. A three minute interval is adequate for tracking pedestrians as a walker won't move very far in that time. We use smart beaconing for vehicle trackers, although the parameters we use are rather skewed to our requirements. Before introducing SB we experienced a lot of de-sensing of voice channels from APRS trackers in vehicles parked at checkpoints. The SB settings we use specify a 20 minute interval for speeds below 5 mph, then increase to 3 minutes above that speed. Since most event vehicles move fairly slowly when they are moving, there is little benefit in a long-slope pattern up to some high speed. The corner-pegging parameters still need some adjustment to reduce extraneous reports in roundabout-rich areas.

All of our trackers have SIRF III GPS chips.

Interesting observations Bob, thanks for sharing.

With respect to the APRS networks you set up...

Are you operating on 144.800?
If so

do you rely on existing digipeaters, or are your events within simplex range?
What issues do you have with non-event traffic?
Do you feel limited in terms of beacon time?

In either case, do you use any event-specific digipeaters to provide coverage in the event area?

Most RAYNET events are (if my experiences are anything to go by) engineered for "good" comms (i.e. outstations at least 12dB over noise, TT links 20dB), so the difference between 5 and 10w, as you suggest, won't be noticed as TNC's will happily resolve packets at around 3dB over noise.

Interesting observations of 5/8 antennas, as these have a very high angle of radiation (around 60deg above horizontal). Great for lowland events with higher sited TT's and Controls, probably the worst possible antenna for a high-sited station! Radiation angle also helps explain the reduction in stray RF.

GPS technology has moved on and receivers like the SiRFstarIII are, as you suggest, very good inside vehicles / rucksacks etc. (not withstanding heat-reflecting windows!). The systems I use have Garmin GPS-12s which are not good anywhere else other than the roof of a car.

Panorama CDV - Excellent practical antenna (as are all the Panorama range), we also use the BSV for mast-mounting.

A few comments relating to the earlier posts, based on experience during events in East Sussex over the past three years. All of these points are based on 2M operation:

1. I have done some comparative testing that suggests that the difference in performance of vehicle trackers using 5W vs 10 W is not great, at least over the distances involved in most events in this area. I plan to do further testing.

2. On the other hand, antennas do make considerable difference. We use 5/8 wavelength antennas on mag mounts for vehicle trackers and they outperform 1/4 wavelength antennas, both in terms of coverage and reduced amount of stray RF inside the vehicle.

3. We have deployed eight different TinyTrak 3 trackers and have never had the need to reset one during an event. I have seen them lock up in testing but only when using a 1/4 wavelength antenna.

4. For several years we put the GPS antennas on the vehicle roofs but a recent series of tests has shown that they work equally well when inside the plastic toolboxes that hold the other tracker components. This considerably simplifies installation at event start.

5. For pedestrian trackers (i.e., sweepers) we use BeeLine trackers, running 5W. Running from an 1800 mAH battery they are still producing full power at the end of a four-hour event such as a half marathon and would probably run even longer. This is based on a 3-minute beacon interval.

6. We have had good results using Panorama CDV antennas for bicycle trackers, pedestrians and a canoe.

A4 sized Waterproof Photocopy/Laser paper

We have all seen and some have used the A5/A6 sized "Rite in the rain" waterproof note pads - well if you need a large size sheet of waterproof paper (A4) - for map handouts, checklists etc then here's a solution: http://www.rvops.co.uk/a4-all-weather-white-copier-paper-1748.html

They can also provide different coloured paper as long as you like military green or desert sand colours!

Note could be useful for printing out specific sheets from your handheld/mobile equipment handbook - showing the key programming instructions. The waterproof paper can then be left in your Grab/Go bag or vehicle. Also useful for printing out operating instructions/maintenance info or just printing out waterproof sheets for a log book for a repeater site.

Usual caveat - I have no personal or business connection with this company or product.

'Black hole' communications problem solved

19 March 2012

Cassidian in Newport has developed a totally secure mobile system which overcomes problems for emergency services operating in areas around the world with communications 'black holes'.

Limited cellular coverage in some areas, including parts of Wales, has traditionally posed communications difficulties for police, fire and ambulance services.

Now, technologists at the UK headquarters of Cassidian in Newport have succeeded in encapsulating in a case the size of a cereal box a mobile device that optimises and maintains a communications network in problem geographical areas or severe weather conditions.

Cassidian has chosen the Brecon Beacons in Mid Wales as the ideal testing ground for the system, known as Mobile Internet Protocol Node.

The system has been designed to make it easier for military and emergency response services to communicate using voice, data and video. It can be carried in ground vehicles or, for example, in helicopters, and does not need a skilled operator.

Dr Mark Bentall, Chief Architect of Cassidian, said: "Existing communication technology used by military and emergency services consists of radios that operate over multiple wireless networks. During peak traffic times or in extreme weather conditions these networks can become congested, restricting flow and impeding operations.

"This system takes a holistic view of all routes from sender to destination, taking into account external conditions, message file size, priority, security level and physical location. It then decides on an optimum route for the information. Users can be confident that a message will reach its intended audience regardless of conditions."

Cyber security is now essential for modern military and emergency services, and the device incorporates Cassidian's latest encryption technology.

Dr Bentall added: "We have combined network mobility, security and quality of service delivery in a highly integrated, functional package. It is designed to remove complexity from the user and reduce the need for communication planning. A Mobile IP Node-based system can provide high levels of trusted communications without the need for skilled operators or users – they can simply send a message and know that the system will efficiently deliver it."

Apparently, it been hoped that a new underwriter would take on the policies, but unfortunately none could be found, and the company had no option but to write to policy holders informing them of the decision. It is advisable that anyone potentially affected should contact the insurance company direct.

If the insurance is for personally-owned radio equipment, owners could look at adding it to the all risks part of their contents insurance.

For group equipment, contact should be made direct with the group's brokers.

Use of IT-based systems in RAYNET : Bands & Power for APRS use

Another issue with at least some of the 4m handies out there is that the antenna is not best specified for the 4m band.

On mine (and my XYL's for that matter) the antenna is supposed to cover from 66MHz to 88MHz so it's not going to be at its best at 70MHz. (Some variants of the Wouxun handie came with separate antennas for 66-77MHz and 77-88MHz.)

I seem to recall there was an article in a RadCom not so long ago that showed how much wire you needed to add to the 66-88MHz helical to centre it rather closer to 70MHz.

Alternatively there are better, non-helical, antennas available - Carole and I both have one.

Given that hand-helds are capacitively coupled to your body as part of the groundplane, it stands to reason that 4m is more susceptible to body proximity.

Remember that anything within 1 wavelength of an antenna will affect it, the closer the object is, the more the effect, so as a proportion of wavelength 4m is twice as close.

I have had limited experience with 4m handheld but have found as a handheld band not to be that great. Perhaps others have more experience? Maybe it's just my setup but performance was way down from a 2m handheld. I'm sticking to 2 and 70 for handheld use. Seemed very susceptible to body position etc than other bands.

Perhaps going off topic.

Just my twopenneth.

Thank you for clarifying that Jim. I wasn't aware who was and was not using that band for those activities ;)

It also makes it easier in future for our green-laning groups as the there are at least 4 within our group with amateur licences, 3 of them in Raynet and all could be adapted to use low power 4m radios with trackers. Ooh, such options... Of course, having my own 4x4 would help but at the very least I could have portable gear for going in another 4x4 or something :D

I think I shall probably try and get hold of one of those handheld 4m/2m radios from Wouxun to mate to the other bits...

I also like mounting gear that can be classed as 'virtually indestructible' ;) Always good encouragement. I would also think that at least having a GPS/Dongle setup it would be a relatively small matter to substitute a radio on a different band for the task in hand...

Now. All I need is a job to pay for all these ideas ;)

Our use of 4m was very specific and I'm not aware of any other Groups that use the band for APRS. In our case it's Aylesbury and Leicester who own the trackers as it's people from those Groups who ran the data system on Mull, only a few ancillary bits were personal items.

Antenna-wise we use Panorama BSV's for base (1/4-wave pole-mount) and CDU's for rucksacks (have a versatile clip system that can be mounted at any angle). Both are virtually indestructible.

I've seen photos of a few Groups that have been very successful with cycle-sweeps and have either a small trailer or panniers for the radio kit and some innovative systems for mounting antennas.

Thank you for your responses. I am keen to try that side of radios and have been playing around with other power systems for a while.

I have a spare GPS that I could use right now plus all the cabling for in or out of a vehicle, and I could scrape together the money for the tracker just not a radio.

I have seen a portable operation in place that had a rucksack with a frame, batteries low down, an SLA/Gel-Cell and with a 10w Icom radio for HF use, the antenna was bolted onto the side of the rucksack and that was about a meter tall but started from lower than the base of the rucksack and could be extended.

I'm still a newbie with antennas also and these times of planning and doing things tend to be often seasonal due to work levels. But I'd like to get my mitts on a 4m mobile unit for use on that band as well as APRS at Raynet events such as you described.

I am not averse to loaning out my own gear at Raynet events but as other operators have put it, to take care and ensure that it is returned....

Then again, I've not really tried the 'sweep' or 'foot mobile' option as I am a tad unfit. Cycling sweep is doable, and I have even more gear available for that which would be more suitable for the task at hand.

More exercise is clearly required anyway ;)

With respect to TinyTrak -v- OpenTracker....

From the outset, I've always viewed APRS with "RAYNET" eyes, i.e. needing something that is reliable, can be presented to the User Service without jargon and clutter and trusted by them.

We started out with the TinyTrak back on 2001, but had serious problems with the hardware locking up and needing a power cycle to kick back into life (RF getting into the processor). Despite metal-boxing and ferrite / choke filtering all inputs we never resolved the issues completely, which we believe was RF pick-up on the GPS data cable.

I have also been on a number of other Groups' events where TinyTraks are being used and heard regular messages from control for the operators in the vehicles to reset them as they had locked up. Not good!

In 2007 we switched to the OpenTracker.

The OT is a professionally designed board for RF environments with proper screening & board ground-pane, plus it's supplied in a metal case. Never had one fail! We use the original OT1m, it's replacement (OT1+ and SMT) is in a plastic case, but the OT2m and OT3m are metal cased. We've never tested one of the plastic-cased OT1+'s.

(No commercial connection etc., just believe the two products are, in design terms, poles apart!).

Obviously any band can be used for APRS, availability of equipment and event requirements shape what is actually used.

Our use of 4m stems from the Mull Car Rally, where 2m & 70cm were not usable due to the extensive voice network (16 interlinked talk-through units!). We had some low-band kit available for the initial experiments in 2001, then the huge number of Ascoms came available from RATS so we standardised on them.

We run 10w, never tried lower (problem with commercial sets is the missing signal meter, so you don't get a feel for signal levels). On Mull this was felt to be about right given experiences with voice comms, but in less mountainous terrain 5w may be enough.

Trackers run for 24+ hours on a 24Ah SLA using 10w, so no life-extension requirement to use lower power. Very occasionally we get breakthrough onto 2m when a mobile is right next to a talk-through or digi aerials are too close, but otherwise no problems have been experienced.

Our approach has always been to set up a separate closed system for a number of reasons.

High beacon rates from each station. We use a 1 minute cycle to ensure the location is as real-time as possible (with 12 mobiles this equates to a beacon from somewhere every 5 seconds). Put this on 144.800 and you will not be popular!
Pre-existing 144.800 digi's are rarely in the right place for good event coverage, so you end up adding your own anyway.
To guarantee we get the beacons, we don't want any non-event traffic on the frequency. We use tracker time-slotting to eliminate collisions, which ensures over 95% of beacons reach control. With other traffic on the frequency this can very quickly get below 50% and if 144.800 is busy in the area, can be low as 10%.
Very specific tracker and digi configuration to reduce digipeating repeats, which in turn helps digi battery life.
Digi's have telemetry enabled to monitor battery state so we can change them before the system fails.

Where possible we do gate the information to the Internet so those with iPads / smart phones etc. can monitor the system (this was been done over the weekend so the organiser could see where the buses were), but this is one-way.

Downside of using 4m portable is the lack of equipment (although Wouxun hand-helds are now available) and size of aerials when rucksack mounting.

For portable tracking 2m or 70cm is the logical choice, with all-in-one hand-helds and dedicated trackers being available, but be aware of the battery and external antenna requirements. GPS's are handheld battery killers (usually 80-100mA on top of the radio RX consumption) so spares need to be carried or available at checkpoints if out for more than a few hours. The handheld in a side rucksack pocket will be a lot less effective than a clip-on 1/4 wave, something to consider if you need wider-area coverage or a more reliable beacon.

We have tried portable tracking on 4m using a Yaesu FTH-1010 handheld, helical 4m antenna and 2.1Ah SLA (all in a little box). The overall weight and bulkiness made it impractical and the kit was rejected by the sweep team after covering the first couple of checkpoints. Also top-mounting the GPS on a rucksack is a challenge.

Our portable dilemma now is what to do, as we have significant investment in mobile 4m equipment, but the lightweight kit is available for 2m. One option being explored is to put 2m receivers on the digipeaters and cross-band the data onto 4m for onward transmission.

2m is the norm but as you see 4m can be used as well as 70cm. May depend on what kit you already have radiowise and also what your members have. Also whether you want your aprs traffic on its own freq away from the national and igates.

Power is a consideration but on a reasonable course the siting of suitably placed digipeaters is the key for good aprs coverage. 5w from a handheld works fine then. That's all you can have when sweep teams etc are on foot.

We use tinytraks but they all work and each group has their favourite.

Hopefully Jim will advise on what powers were used etc to cover the course. Hope you had a good time at he event.

Before today I hadn't seen a working setup of APRS using anything other than 2m, although thanks to the members who setup the Endurance 80 in Great Missenden this weekend showed me what could be accomplished for both the radio and the management side

I was steered towards the use of OpenTracker and coupled with a GPS and radio it seems to work well enough. However, those seem to be with mobile radios that would probably be putting out betwen 10w and 25w through a magmount antenna on the vehicle.

As I have no experience of this band or the setup, could those in RAYNET who use APRS on these bands and power tell me here how they fared using that power on 4m over 2m.

Also, how much difference would it make if the transmitter was only 5w. I have seen there are Wouxun hand-held radios out there that cover 4m and 2m but I don't know how well they would mate to the tracker/GPS.

The Opentracker seems to be about $40 right now and a mobile 4m transceiver can be picked up for under £100 whether 12v or handheld making things more possible. It would be helpful to retain other aspects such as if it is going to be hand-portable, using a GPS that would be on a cable that the operator could view it rather than just taking instructions from control to what they can see on the screen. If mounted in a vehicle then it is sometimes just easier to have it setup and secured away, but most plans have their postives and negatives.

No doubt this will make more sense after I've had more some sleep ;) but it was certainly a bit more of an eye-opener this weekend with the technology and paperwork :D :D

Hello again All,

Well, I didn't dream-up the channel-order and tone myself..... we have had them that way for about a year now.... Think it is time to re-new permit soon too.

Jeff, I see your point about having a selection of CTCSS tones.... As we have got PRP's in NEH and so have NWH, we could do it easily. The PRP's can have a CTCSS menu of up to 9 tones ( off the top of my head ) that can be selected on-the-fly, while on any programmed channel. I will be re-programming the NEH radios to use that system of working. I already use that method on my PRP73's that I have for amateur use.

Time to get the programming lead out before I get some sleep....

Best wishes all,

Ian.

If you request a copy of your current permit via the webiste it will come with a copy of the notes.

Regarding programming and CTCSS tones; whilst it is useful to have a common tone frequency for inter-group interoperability, bear in mind that sometimes that is not what you want! Also there are many other users on the frequencies using 'random' tones. So if the radios that you use have enough channels it is best to program in the same frequencies with different sets of tones so that at least you can shift away from problem, or be on the same set as the event organizer's sets.

Hello All,

          Having read the above and followed the link to our website, stating the high-band UKG frequencies, I thought that our website showed different frequencies and tone to how I had programmed them.
          That would also mean that North-West Hampshire have the same incorrect ( as far as shewn above ) frequency-order and tone.
          That made me look on my laptop to see what the programme had been set to for their's and our PRP's. My laptop does indeed show that we have got the correct channels, but in a different order ( a la Eric Morecambe ) to those shewn above and have also got a different CTCSS tone set.
          This surprizes me as I programmed these radios to the ( obviously, at the time ) published suggested frequency-order and tone. When did the suggested channel-order and tone change ?

          If all other groups have their's set as in the list above, I will arrange to re-programme all our's and NWH's radios to match, to avoid any confusion.   Please advise.

On a different thought:-   There is mention on the notes on PBR on this website of suggested SELCALL settings, if used. That would only really be useful if working to a central base radio, not between each other. The only use I can think of would be for ident of who was transmitting on any recordings made and then only if set to transmit the ANI when keying-up.
To identify down to the 'radio' would need for a standard number of digits for everyone's ANI.
Following the notes on the suggested method of determining these digits would mean.... 2 digits for Zone and 3 digits for the Group, with 2 more for the radio's ID. I cannot imagine any group having more than 99 radios ! That would allow for more than 10 radios, or for other info to be sent. Apart from knowing which radio was transmitting, would we or anyone else need this ?    Do any of our RAYNET Groups that use UKG, use any form of SELCALL ?

Best wishes all,

Ian.

Plymouth University joins 3.5 million Euro European project to improve communications between emergency services.

Plymouth University has teamed up with experts across Europe in a project to develop new technology which will allow emergency services to communicate together more effectively.

The University has received funding in the region of £397,000 (€478,000) from the European Union to take part in the project, named ‘Geryon’.

Currently emergency services throughout Europe, such as police, fire brigade, ambulance services and coastguard, use various systems to communicate. This project looks at bringing different systems together using a new technology to enable better interoperability. It aims to ensure seamless communications regardless of access and take advantage of broadband networks.
