<div dir="ltr">Not at the moment as the firmware currently stands. However,
that's not a bad idea.<br />It could simply act as a totally "dumb" controller
and just repeat the input back to<br />the output.<br /><br />JIM<br /><br /><div>

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?

<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<span class="ecxApple-converted-space"> </span><br />portable/mobile operation
with a mobile/portable Internet connection in both the GPS-based<br />and
non-GPS-based environments.<span class="ecxApple-converted-space"> </span><br /><br />JIM WB6NIL<br /><br /><br /><div>
