You may in fact need a transistor circuit. The RTCM CTCSS needs to have very near rail voltages. If your radio isn’t pulling the CTCSS input to very close to zero volts it won’t work. So do check your CTCSS output while connected to the RTCM. Make sure it goes to zero and build a circuit if not. I like to use VN10K’s for that.

tried every setting, and upgraded to 1.46, no dice. I'm going to try
and build a transistor circuit for it and see if that helps
It would be nice if there was a readme file that explained what the
voter-plus.cry file vs voter-smt.cry was, and some updated docs on the
actual rtcm... they are heavily out of date and aren't very detailed.

also a changelog would be nice?

If your CTCSS signal goes low with a tone you want to set the RTCM CTCSS to
inverted.

I have noticed my CT decode is not working on the RTCM's either, no one
seems to know why... even the mfg.

Mine takes it from carrier mode or something, even though I know the ctcss
line is working
for whatever reason the rtcm will not honor the signal - i.e. anyone without
a PL can bring up the system, yet noise and such does not cause any issues,
I had an interference issue with my repeater, as it is at home now, test
site before I get it up on the mountain and I would get feedback, causing it
to loop, now with the RTCM this doesnt happen, it's almost like a smart
squelch anyway even signals a bit off freq don't seem to trip it up.. anyhow
Maybe PL is not really usable with the RTCM??? No one seems to be able to
answer why that is either.


Maybe in your case the RTCM is sinking too much current?
what settings do you have for the RTCM? btw...


12 - External CTCSS (0=Ignore, 1=Non-Inverted, 2=Inverted) (1)
13 - COR Type (0=Normal, 1=IGNORE COR, 2=No Receiver) (1)
14 - Debug Level (0)
17  - DSP/BEW Mode NOT SUPPORTED
18 - "Duplex Mode 3" (0=DISABLED, 1-255 Hang Time) (1/10 secs) (0)
19 - Simulcast Launch Delay (0) (approx 200 ns, 5 = 1us, > 0 to ENA SC)
20 - Ext. CTCSS Input Threshold (0) (0-1023)

One thing I noticed was the #20 but I can't seem to set it to anything...
unclear what that is for then.

also im on S/W Version: 1.46 03/04/2014
Seems to be more stable but not sure if it would help you at all -

Running version 1.41 .
Have 2 rtcms connected to mtr2000 , thunderbolt gps , pretty standard
setup.
My simulcast is working great, however I can't get ct decode to work
properly. It's either in carrier mode or it doesn't work .

Odd things happen when I put what I assume is the correct settings in the
ct and for config on the rtcm. The rx light flashes and sometimes let's a
signal thru , but my repeater sorta goes flaky like the rtcm is pulling the
line down and flaking it out. The voltage pulsates on the CTCSS line and the
repeater receiver light goes out when it is actually receiving a signal.
Very odd .

Is 1.41 the best version? Any ideas what I'm doing wrong??
I'm using the rdstat2 pin on the MTR for CTCSS decode and it reads 5 volts
when receiving a valid pl .

Thanks in advance
