One other thing. If you are going to use simpleusb you need to remove or change the name of usbradio.conf  - I just rename it usbradio.conf.xxx   and also change the rxchannel statement in rpt.conf - rxchannel=SimpleUSB/usb

It is always easier to get things going with simpleusb assuming you have a hardwired cos or ctss line to the URI interface. In many cases usbradio just makes things a whole lot more complicated than it needs to be. If you are using the URI use the COS input (pin 8 as I remember) from the radio. All you need to do is set the COS in simpleusb.conf to invert or non-invert depending on the radio output. Make sure duplex in rpt.conf is set to 1.

Us, all works from that side... The red PTT light does not activate when connected to the radio, even during an I'd transmit. If I send a tone to the radio from CLI, it will light, and come out over the air. It's behavior is confusing. The system responds to COS_det on receive, but no voice comes through, acting like no ctcss detected with =dsp...
When the computer died, I just loaded up ACID, then copied over the .conf files, and located the URI using lsusb, entering the data in the usbradio_tune... File.

Well first thing is the URI's green light blinking at a steady rate when asterisk-app_rpt is started? You can also exercise the PTT off and on in the CLI.  Do susb ?  or radio ?  to see commands depending on whether you are using simpleusb or usbradio. Also do you get any errors at the CLI screen or look in /var/log/asterisk/messages? Does 'lsusb' at the linux prompt show that the FOB was detected?

Asterisk is not talking to the radio via the URI for some reason. Is it asterisk, the URI, or the radio? Just trying to eliminate each possible issue. I often feel like I'm shooting in the dark with this system. If it wasn't for this list, and folks like yourself, I'd be totally lost... May be lost anyway, but inputs keep me going :-).  I really appreciate your insights and inputs. 

Yes, app_rpt was running... Wondered if I needed turn stop it first. 

Thanks much!Bobkk6ecm

Bob,

 Do you have a reason to run uridiag?  Do you suspect your uri is bad? If not there is no reason to run it. Perhaps  app_rpt is running also? You would need to run that exclusively.  Stop asterisk or reboot without starting it before running uridiag. You would need to make up the test cable as per the DMK site to test it.

the snd-pcm-oss modules needs to be loaded. It creates /dev/dsp, /dev/mixer
modprobe snd-pcm-oss  to load

lsmod  to check if it is loaded - or  ls /dev/dsp   - is should be there.

Any ideas how to solve this one?

# uridiag

URIDiag, diagnostic program for the DMK Engineering URI

USB Radio Interface, version 0.8, 04/26/11

Found CM108AH USB Radio Interface at 002/003

Unable to re-open DSP device 1: /dev/dsp1

Segmentation fault

Do I need a loopback?

Thanks,

Bob
