Jim the simple repeat idea is good we just need to make sure it can id in that mode.

This would be a good function or to add in the future firmware!

Subject: RE: [App_rpt-users] Allstar RTCM (Radio Thin Client Module) is nowavailableNot at the moment as the firmware currently stands. However, that's not a bad idea.
It could simply act as a totally "dumb" controller and just repeat the input back to
the output.

If you use RTCM as "generic" radio interface on the hill and a linux box at a remote location connected over an IP connection and you loose the connection can the RTCM failover to be a minimal repeater controller on the hill?73 de N5HC/Conny

Of course, "Internet" can mean either some sort of public Internet connection, or a privately-provided
Internet connection (low-cost microwave link(s), etc).
The only limitation is that an RTCM/Voter module *must* be located on the same LAN as the Linux
server, to at least provide a GPS-based timing reference. A system could be set up with a server
located in some sort of datacenter "on the ground", and all the radios could have an RTCM "on the
hill" with them, and as long as there is Internet connectivity of some sort between each of them
and the server, the system will work nicely. That is providing that there is an RTCM located at
the server location also (whether or not that particular RTCM has radio hardware connected to it
or not).
One minimal Linux server can easily support 1 or 2 dozen RTCM's (on 1 or 2 allstar nodes),
and a larger server could easily support MANY dozens of them on dozens of allstar nodes.
Of course, you REALLY dont want to put too many of them on a single server, being a potential
single point of failure. For pretty much any practical purpose, the reasonable limitation is
the point of failure/redundancy issue, not technical limitations.
I'm not sure if you were clear on this, so I thought I would mention that the RTCM is not just
usable as a GPS-timing-based Multi-Receiver Voting system and/or a Simulcast Transmitter system.
It can also be used as a "generic" radio interface for a conventional (non-GPS-based) either simplex
or full duplex (repeater) radio. The advantage of doing this would be to not have the Linux
host "on the hill" with the radio (as mentioned above). In addition, the RTCM allows for
portable/mobile operation with a mobile/portable Internet connection in both the GPS-based
and non-GPS-based environments.

I have been looking at the Allstar RTCM (Radio Thin Client Module) and it really looks like a GREAT product and addition to the already cool Allstar hardware.Among all the other cool features of the RTCM (Radio Thin Client Module) like Transmitter Simulcasting and Receiver Voting, if I understand the documentationcorrectly you can use this very small Radio Thin Client Module at a remote radio site to set up an Allstar repeater node if the site has internet connection without a COMPUTER at the site?Then you can point the node on the hilltop back to a server on the ground somewhere that is easy to get too?How many total sites can you use Radio Thin Client Modules on and point back to a single server on the ground?If this is the case, All I can say is WOW, how cool!73Marshall

I agree!I was going to ask exactly the same question. Maybe this loss-of-connectivity-failover function could be enhanced to include a simple timed morse ID and dedicated repeater tail tone so you know immediately that something is wrong.Michael.VK5ZEA
