Can't Get Data Programs to Transmit.

I am having trouble getting data programmes, like WSJT-X etc. to work with the IC-705 using WFVIEW and Virtual Audio Cable (VAC). Receive is OK but I can’t transmit. Here’s what I am doing:

I turn on my IC-705 in USB-D mode and restart my computer so everything is ‘clean’. I start WFVIEW but disconnect from radio. I select VAC-A for WFVIEW audio input and output. I start WSJT-X (in FT8) and select VAC-A for Input and Output (Tried other VAC ports as well). I now connect WFVIEW to IC-705. I see audio in the WFJT-X waterfall and FT8 decodes, so RADIO → WFVIEW → WSJT-X is working.

I now press ‘Tune’ (or transmit) in WSJT-X and TXAudio shows -6 so audio is getting into WFVIEW. I switch the secondary meter to ALC and it reads zero. I have checked the Radio Setting and put Data Mod Input to LAN (actually tried all 3 settings), did same with Modulation Input.

On the radio I have tried VOX on and Off. On radio, Connectors Settings, I have tried Data Mod on four settings, but guess it should be on LAN. I have also tried Data Off Mod with WLAN, but I can’t get the radio to key up and transmit data.

Am I missing something? Any help will be much appreciated.

Rather than metering ALC, try looking at the power output as well as the power output setting.

Everything you’re doing seems correct.
