[arm-allstar] BBB/Pi or RTCM

Thanks. As I have written I am a full time System Administrator and load the 
OS on PC's all the time. We already have a PC in a data center that our 
current RTCM talks to. We need to add remote receivers and there's my 
question. RTCM or use Pi's. Why would I choose Pi's? I know there is a 
reason but I don't know it yet. LOL Please tell me what the secret handshake 
is!!! For the love of Pete. Sorry. I got carried away.

Hi,

The RTCM is currently the only AllStar-based voting solution.
Technically speaking, you'd have an RTCM at each site where you've got a
receiver or transmitter. Then, all the RTCM's would connect back to a
central server (which could be in a data center, etc.) via an IP data
network. The central server would perform the actual voting action and
send the resultant audio and telemetry back the the transmitter site.

You could use a BBB, RPi2 or regular PC as the central server, the RPi2
or PC being preferred for new installations.

the time here. But I don’t read questions like, should I use a BBB or a
Pi instead of a RTCM if I want a voted RX system with a central TX site.
Our Los Angeles area TX can be heard for 150 miles in most directions due
to our great location. But our RX is compromised by having the outputs of
two repeaters within 15KHz of our RX frequency. So... we need a higher RX
field strength. Voting multiple RX sites seems to be the solution.
