you need to put a capacitor in series with the discriminator audio. Then run "radio-tune-menu" and set the levels. I believe option 2 will auto set to get you started.. Chuck K0XM byrg.net On Sun, Nov 28, 2010 at 10:17 AM, Rod Schnell <n2oyj.ham@gmail.com> wrote:
I'm sure this problem arises frequently (and I have read and tried most solutions in this and other places). SETUP: Motorola M1225 w/ flat audio in simplex mode -->> URI adapter -->> Asterisk (CentOS ISO from AllStarLink link)
I have no RX audio on iaxRPT. I have tried different radios & different computers. Here's what is happening: 1) start asterisk and go in to the CLI at verbose level 3 or 4 (at this point the node appears on the AllstarLink active list) 2) start iaxRPT, with debug level at 2 3) connect to node via iaxRPT. get the following * Verbosity is at least 3 -- Hungup 'IAX2/gui-4704' -- Hungup 'Zap/pseudo-1686370267' -- Accepting AUTHENTICATED call from 68.95.77.100: > requested format = gsm, > requested prefs = (), > actual format = gsm, > host prefs = (ulaw|gsm), > priority = mine -- Executing [27234@radio-gui:1] Rpt("IAX2/gui-3545", "27234|X") in new stack == Spawn extension (radio-gui, 27234, 1) exited KEEPALIVE on 'IAX2/gui-3545'* 4) click TRANSMIT on iaxRPT (or via radio), unkey. Get tone then ID over both radio and iaxRPT. 5) TX on handheld radio and do test count. NO audio heard on iaxRPT. Audio is heard on radio connected to URI adapter. When handheld unkeys I get the tone signaling end-of-transmission. (This leads me to understand that asterisk IS seeing the radio receive.) 6) with two computers running iaxRPT, when one TX the other one can hear it. (This leads me to believe that asterisk IS working.)
So with all of the above I can only see two possibilities for things to be wrong, either the URI adapter has gone bad or I've not got something correct in the program. Any help would be greatly appreciated.
