I had to make a new cable for a different radio I was using.
The pinout of the 8 pi mic is
Pin 7 GND - - - - > Pin 13 GND on URI
Pin 6 PTT————–> Pin 1 PTY on URI
Pin 5 wired but more on this later.
Pin 8 TX audio - - - - - >Pin 22 Left_Out
Pin 4 RX audio———–> pin 22 Mic in AC
Under al-menu and in the tune interface CLI I am able to flash the PTT and listen to the 1000 Hz tone, and also able to receive and calibrate RX audio.
But, echo does not work. Then, I exit the menu, run asterisk - rvvvvvvv and am able to decode DTMF but like if I go *70 I read the response on the CLI but when the playback comes, the red light on the URI does not come on, I can see the digits play out on the CLI, but there is no response from the URI to the radio. I switched URI’s and same behavior, so something with the cabling may be the issue here. My message got cut off, I was using my phone and there was a power outage, had to redo message, anyways, not even my callsign went on my original post.
Thanks again, 73
