Icom IC-7100 - No Transmit Audio

,
1

Hello!

I recently purchased a Digirig (Icom model - that supports CI-V). I have the following:

Digirig Audio - 13-pin accessory port on the back of the IC-7100
Digirig Serial - CI-V port on the back of the IC-7100

I have the USB cable connected to a Windows machine running Windows 11. The USB Serial interface was recognized without any issues. The audio input/output were also recognized without any issues.

I’ve been trying to use WSJT-X and Direwolf to test TX/RX. I can verify that Digirig is receiving audio and can PTT key the radio (via CI-V).

I have the Monitor option enabled on the IC-7100. I cannot hear audio transmitting when I key the radio/send an audio signal. I also do not see any activity on the VU meter on the front panel of the IC-7100.

Could someone provide some insight as to where to start looking to debug this issue?

Thanks in advance!

Looks like I just figured out my own problem. :-/

I had the DATA MOD setting set to USB instead of ACC. Once I set it to ACC and tried to transmit, I could hear the signal via the internal speaker.

Sorry to raise the issue when the issue was my own.

Hello, I have a similar issue with Digirig and a Icom IC-7100. I use the Data (6-pin din) connector for audio signals. RX works very well, but there is no TX audio sent by the radio. I checked the cable with another Icom radio, and it works well on TX, so the cable, the Digirig & the sofware are OK. It looks like the IC-7100 doesn’t use the TX audio on data connector. I tried every possible setup in the “connectors” menu (Data mod, Data mod off, etc), but still no TX audio. Any idea? Thank you. VE2BAP
