ICOM 756PRO, Digirig with Ci-V and ICOM DIN8 Cables Kit for Digirig Mobile

Hello, I’m trying to configure the 756Pro for use on digital platforms (winlink, WSJTX etc…) I have the following:

756Pro
Digirig with Ci-V
ICOM DIN8 Cables Kit for Digirig Mobile

CAT works great but audio will not go through either way. I ordered the cable on gigiparts and the digirig from the digirig website.

I shot the pins and this is how the cable is wired

tip: pin5 (AF detector)
next: pin4 (Mod input)
next: pin3 (send)
next: pin2 (ground)

Is that correct? I have read the manual back and fourth and I cannot find settings that have to be changed to use the back din connection. I have also tried USB-d. I’m sure I am missing something simple.

Your help would be greatly appreciated.

Thanks, Scott KQ4VET

Looked up the manual for the transceiver, this may be relevant:

Thank you, Denis for looking that up. I have checked that previously and it did not make a difference.

The manual says that data modes mute the mic that implies that the signals are picked from the accessory port.

Is Digirig side of the configuration taken care of? You can monitor the incoming audio on the computer’s speakers with “listen” box enabled in Digirig’s recording device:

I’m almost embarrassed to say, but the din cord was not firmly seated in the socket. The problem now is that my ALC is so high it splatters my signal. I cannot figure how to turn it down on this 756PRO, but I’ll keep working at it. When I remove the din plug to radio functions normally. I will watch the video and see if that fixes my issue. Thank you for your response.

great video Denis. I think AGC was my issue.

Thanks for your honesty!

It took me a while to catch this the first time, with the Kenwood connector into my HT. Ever since then, I make reseating all physical connections part of my troubleshooting.

Not a problem, honesty is important! I was able to get the system fully functional on winlink vara and WSJTX.

Thank you for all the help
