On my 3 repeaters I am getting receive audio directly from the output pin of the detector IC chip and I have no problems, all setup worked exactly as described in the documentation.  All TT from all brands of radio all work perfectly.  

A friend has a repeater that is getting output from a connector on the back of the radio that says discriminator audio out, but looking at the schematic I can see that there are lots of circuits and filters in the line between the detector IC and that output.  For his system none of the setup steps worked correctly and we have to just get it as close as we could manually.  For that system TT's only work from a very few radios and not at all from some and intermittently for others.

I would suspect that you are not getting direct enough unfiltered audio, or you did not follow the setup procedure exactly.

There is no CTCSS decode when using the RTCM's.  The radio must have a hardware CTCSS that sends a logic level CTCSS detected signal to the RTCM.

Or just use carrier squelch that is in the RTCM firmware and works only if you get good unfiltered discriminator audio.

I highly recommend getting rid of these lines

thresholds = 255,110=5

linger=6

thresholds = 255,110=5

linger=10 

Everything works better without them IMHO.

It is a good idea to start with a big value for buflen to start with and only trim it down after everything else is working well.

If it is all working but you do not like the squelch close action, then I have alternate firmware to fix that issue.

No idea how it got fixed other then multiple reboots later - no PL being heard now that is great!

two other issues I have with the voter modules (RTCM) can those devices or can the allstar/asterisk do 

CTCSS on rx, I see it can do it on TX but I want it to be my tone decoder - Just seems odd if they cannot

since it would for a USB device why not here? 

Two, for some reason one radio I have Wouxun the DTMF digits do not work except the 9 when watching the 

asterisk -r .... except sometimes if I hold each digit for 2-3 seconds then it does.  Is there a setting I can adjust? 

As far as I can tell by the config and listening to my signal levels sound about right/proper deviation etc.

The Baofang works 100% of the time with the briefest of key presses even if I tweak the rx a bit. When I monitor 

the output from the wouxun through the node the tones sound distorted - from the baofang they sound clean. 

Maybe it's the radio?

Thanks,

Hello everyone,

Trying to setup 2 RTCM's for voting - starting off with 1 for the master timing source - no Radio.

and one currently at the same site for testing purposes, both have GPS configured & working.

The radio is a GE Mastr II base - I located a point where the CTCSS decoder gets the discriminator audio 

and removed the board for CTCSS decode. Plugged in the audio to the RTCM there.

I do hear the audio, but am having multiple issues, first audio sounds OK locally (repeat) but the biggest

issue there is the PL is loud and plfilter = y in the voter.conf appears to do nothing for that.

Second issue I am not seeing a way to decode PL either in the RTCM or in asterisk from a voter.

I know with usbradio/simplusb it has the option but from what I know those are not going to do anything here?

also during the RTCM setup the SQ adjustment appears to calibrate go from flashing to solid on the LD3 indicator.

but when adjusting the SQ pot 10 , 50 , or 150 turns does nothing to extinguish the LD3 as it should, unless I am

misunderstanding the directions - does not make sense. Anyone know if there is something I could be missing?
