[arm-allstar] 2 RTCM's for voting application with one not showing COR

[Stuart Whitmire]

Good evening all,

I just got my second RTCM in and I'm attempting to use 1 as a
master/transmit and the other as a RX only voting site.

The master RTCM appears to be working fine. However the RX only RTCM does
not give me a COR indication, no matter if I program the COR logic to be
active low or active high on my Motorola XPR mobile.

On the master RTCM, I'm using COR to active low and it's working just fine.
On my RX only site, I have it currently set to active high. And the XPR
radio is sending 5 volts into the CTCSS pin on the RTCM. Going through the
status page of the RX only RTCM, I see the EXT CTCSS IN value change
according to if it receives a qualified signal or nothing. However the COR
always stays at 0. On the master RTCM the COR will change from 0 to 1 and
allow audio to pass and be voted.

Here are some screenshots of the RX only voting site:

This one with no qualified signal into the receiver:

No matter what I set the logic to, the COR never goes to 1, like the master
RTCM does.

And I just tested the SQL pot value set at 0 and still no COR indication.

Also I have these receivers sitting right on top of one another. So I don't
know if the GPS location would cause this RTCM to stay muted or not. Or if
it could be a setting in the voter.conf file or some other file.

I feel that I'm so close to finishing this thing....

Has anyone ever seen this issue before?
