[Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work. What's broken?

[Richard Ferch]

Like Wes, I have an original K3 which I have been using in AFSK-A for
years. I use N1MM+ with either MMTTY or 2Tone as the RTTY "engine". A few
months ago I installed the KIO3B upgrade in my K3. After I installed the
upgrade, AFSK-A RTTY worked right from the start using the USB audio codec.
I had no difficulties in getting it going.

Jim,

Thank you very much for confirming that what I see isn't due to a broken K3.

I agree that if firmware can fix this, it would be very nice. Elecraft had
this particular feature listed in the feature set for the upgrade, IIRC,
which is a large reason I splurged on the upgrade. I didn't want any more
external interface confusion.

On to configuring for FSK and perhaps playing in BARTG a little.
