And in rpt.conf you should specify only ONE zap channel:

Thank you Steve. We do have all of that setup or as you suggested. Went back and double checked after reading your post just to make sure.

Please elaborate on how you are trying to connect. When do you get the

I'll try to ASCII out how we're connecting to our radio:

Radio PCI Side Card

Ext Spkr => 1 RXA CVC Sense => 2 COR --not used-- => 3 UIOA --not used-- => 4 Subtone PTT => 5 PTT --not used-- => 6 UIOB Ext Mic => 7 TXA RF Ground => 8 GND

A couple of things to note here: Tying speaker audio to RXA is not the preferred method. RXA should be tied to the receiver's discriminator output, or to a point where the audio levels are less than a couple of volts peak. Pin 8 should be tied to DC ground. If that is the same as RF ground, that's fine. Microphone inputs tend to be very sensitive. You might need to add some attenuation resistors to the microphone input to knock the audio level from the card down so that you can easily adjust the level. If there is a line level input to your transmitter you'd be better off using that.

With that attached, just through an RJ-45 cable, we load up Asterisk. Then after connecting to Asterisk via a Softphone we try to dial the radio. Our extensions.conf file looks like this for dialing the Zap channel:

exten => 205,1,Dial(Zap/1/1999)

Hmmmmm. The idea here is not to talk to the Zap channels directly. Instead of trying to talk to the zap radio channel directly, try something like this instead: exten => 205,1,Rpt,1999|D When your caller calls extension 205, the transmitter should key, and the caller's audio should be heard on a receiver tuned to the transmitter's frequency. This is what we call dumb phone control mode. There are other modes you can use and they are documented in app_rpt.c. Also me sure that app_rpt.so is loaded and running in asterisk before trying any of the above. Use the following asterisk CLI example to determine if app_rpt.so is loaded. linuxserver2*CLI> show modules like app_rpt Module Description Use app_rpt.so Radio Repeater / Remote Base version 0. 0 1 modules loaded Steve Rodgers, WA6ZFT QRV Communications
