Yeah you got it. <br><br>Another thing I probably should have mentioned is that the RTCM/Voter module uses an<br>Internet protocol that is specifically designed to work on ANY Internet connection from which<br>"generic web surfing" is possible (behind any number of NAT routers/firewalls, etc and<br>where LAN address is provided via DHCP). No "port forwarding" or "network provisioning"<br>nightmares are necessary. You can just plug it in and it works.<br><br>JIM WB6NIL<br><br><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">From: ke6pcv@cal-net.org<br>To: telesistant@hotmail.com; app_rpt-users@ohnosec.org<br>Subject: RE: [App_rpt-users] Allstar RTCM (Radio Thin Client Module) is nowavailable<br>Date: Wed, 21 Dec 2011 12:23:28 -0800<br><br>

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