OK then you can use DSP to decode tones. You should have something similar to this to decode cor and pl from DSP in the usbradio.conf file: [usb2417] hdwtype=0 rxboost=1 txboost=1 rxctcssrelax=1 txctcssdefault=103.5 ;default pl tone rxctcssfreqs=103.5 ; rx pl tone to decode txctcssfreqs=103.5 ; tx pl tone to encode if used ;rxctcssoverride=0 carrierfrom=dsp ; decode from discriminator ctcssfrom=dsp ; decode tones from discriminator rxdemod=flat ; neded to be flat for dsp decode txprelim=yes txlimonly=no txtoctype=phase txmixa=voice ; transmit voice only, no tx tone txmixb=no invertptt=0 duplex=0 ; simplex node set to 1 if full duplex needed. rxondelay=0 rxnoisefiltype=0 eeprom=0 Jon VA3RQ On 10/27/2015 11:48 AM, Dave Newmyer wrote:
Thanks for the reply, Jon!
I checked, and in my modules.conf file, I found the following :
Channels
noload => chanusb.so
load => chan_usbradio.so
Am I looking in the correct area?
Thanks,

Are you using chan_simple_usb or chan_USB _radio for the channel driver? It sounds like you are using simple USB.
If using chan_simple_usb then the radio must provide a hardware signal to the URI on the PL input pin. I think its pin 8. So your radio must provide a pl decode line that should be connected to the PL input on the URI.
If thje radio can supply both a COR and a separate PL decode line then connect the COR to pin 7 on the URI and pl decode to Pin 8.
Then you must set up the polarity on the uri to match that of the radio. If the line from the radio decodes pl, then goes low then set in Simple_usb.conf ctcss_from = USB invert. If the signal goes hi when decoding the pl tone then set ctcss_from = USB.
Carrier_from must also be set correctly polarity. sounds like you were using that so its ok.
But if your radio is reprogrammed to give a combined COR/PL decode (in other words the line only goes active with a signal that opens the radios squelch and has the correct pl tone) then it could be connected to the COR input pin 7 and leave it as is.
what you need to determine if your COR/ PL line is going active with the correct pl tone into the radio. if not then you need to configure the radio so that it does. you may need to ground hang up pin to get the pl decode to work. I'm not up to speed on the M120. Others may comment in more detail on what you can do for the accessory pins and programming.
save and restart. see if it decoding tones then.
Also set RX audio to "Flat" if connected to discriminator.
In simple USB there is no DSP decoding of squelch or pl tones from discriminator. this mode relies on the radio to handle those jobs.
If you want the r node to do all that decoding then you must change the node to use Chan_usb_radio driver. then you can set up the node to decode the pl tones in SW and do squelch decoding too.

Thanks for replying! Yes, jumper P551 is set to flat audio. I am working OK using carrier access, just not able to implement CTCSS access.

Did you change or check jumper P551 on the logic board of the radio to ensure you are sending DISCRIMINATOR audio to the U.R.I. ? If the jumper is in the other position (speaker audio) then it won't work.

Hello,
I recently updated from Asterisk ACID to Asterisk DIAL due to hardware (CPU) problems. The install went well, and I am now able to use the Lenovo CPU that I had trouble with (Sept 7, 2015).
I was recently informed that it would be preferable if I were to use CTCSS access on my node instead of carrier access, and I have been attempting to do so, first by activating ctcss via dsp in the usbradio.conf file, then by reprogramming my Mot M120 radio for a channel with carrier access, or the alternate channel with ctcss access and adding a line from pin 8 of the radio accessory connector to pin 7 of the URI.
In Radio-Tune-Menu, choice 4 Auto-Detect Rx CTCSS Level Value passes, but if I try performing a DTMF command like *81, I get no reply from the node.
Any ideas as to what I should try next?
Thanks,
