Many events can be easily covered by a single repeater, no linking necessary.
and of course, simplex operation can cover some events.

Still no answer about how to link them without the internet.

We have one event that’s simplex and five events with one repeater, so that would be OK.


Now the eight events with two repeaters and one event with five repeaters are the problem.

Very simple really
Lets say you wide area main linking network was vhf with uhf local feed into your simplex link via slot1 and going out on slot 2 on all repeaters in range of the vhf to uhf link radio.
Or you could do the linking via microwave or WiFi links on a long range mesh network.

3 g routers are also one way but coverage is always the issue so the direct microwave linking is the best option if you can do in.

We have linked 4 uhf repeaters on slot 1 with net traffic on slot 2 ..direct linking this way can be very tricky if you don't setup correctly
If you need the guidance of a Motorola engineer give me a shout @ m0jhh@outlook.com

A few of us in Central Lancs group now have the TYT MD380 radio. We have used them on an event but do not at present have a digital TT unit for these radios but we will be building one soon.

As the broken RAYNET website and forum is partly back in action, I will add a comment.

In the past couple of months, non-RAYNET member Stuart M0SGS in Pudsey, West Yorkshire, has made great strides in helping to solve the problem of modes not being able to talk to each other.  Currently, DMR can talk to Yaesu System Fusion and analogue FM.  They can all talk to each other if linked.  The technical method of allowing D-STAR to also link in has been solved and it is just a matter of time before it happens.

Note that the inter-mode links are for common or garden speech.  Each mode may have frills such as addressing, picture transfer and short text message transfer and these won't work properly between modes, but speech will.

The connections between Fusion and DMR are done via the Fusion CQ-UK WIRES-X room.  As I type, there are 44 nodes connected to it.  The stations currently linked can be seen after clicking the PLAY icon here:  http://www.cq-uk.com/livefeed.  If there is a callsign suffix, RPT means repeater, GW means Gateway, ND means private node and some stations add an abbreviation of their name as a suffix.  Stations marked in green are in contact with each other, i.e. are talking on the system.   DMR repeaters can be seen here:  http://www.cq-uk.com/linking

It is done via the internet and of course RAYNET may find that the internet has failed when operating in an emergency situation.  The facility will still be useful for some RAYNET events.  It could allow the rapid setting up of long distance communications links to give time for non-internet RAYNET radio links to be established.
