Help with using SSB Voice Caller Software and the 6400

I have my 6400 in the garage and I am on a computer in my home office. Effectively, I am operating remote from home. I use a USB headset connected to the PC as the speaker and microphone.

What I have determined so far is that DAX must be enabled in order for the Voice Caller in N3FJP to work, and it does work. It also seems that I am not able to transmit on the USB headset microphone while DAX is enabled. This means that in order to effectively use the voice caller I need to flip on DAX, activate the voice call, then flip DAX back off in order to use the microphone again.

Is there a workaround for this? It sure would be nice if MOX would just override the DAX setting when used. Is there a way to send the USB headset microphone audio directly to DAX?

    I am not sure if N3FJP sends the correct CAT commands to turn DAX on and off as required. N1MM does it correctly if you want to give it a try.

    Check with the author of N3FJP to send the radio the following commands to the radio.

    The key command is ZZDX1; and ZZDX0; (on and off)
