Re: K3Audio

I certainly agree with Joe on this point. I hear many voice /
background noise signals in the "CW" portions of the bands. Furthermore,
fact is, it isn't legal to transmit such.

suppose if one wishes to run Slow Scan TV with audio in the SSB
portion of the band it might be justified. Otherwise, I still say it is
a terrible idea.

Re: K3Audio

Legal depends on the country of operation, not all restrict to CW only
in the band segments.

If the mike audio is switched with PTT (not always 'hot') so no mixing,
it would work (and is preferred for SSTV mode instead of button of mode
switching between frames).

So depending on his location and need, maybe but overall it's not a good
plan to mix the audio.
