K3 VFO split problem

My K3, Serial Number 556, is not working properly in the VFO split
mode. I only work CW and when I hold split, the CW speed control
light changes to the MIC light. The transmitter will then not key.
Switching back to transceive restores the ability to key the
transmitter. This happens on all bands except 80, 40, and 30
meters. On these three bands, everything works as it should. This
might be a clue, as these are the only bands I normally use. I just
found this out today when I went on 20 meters. I usually use split
instead of RIT, as I prefer to use the larger knob. My firmware is
02.39 and 01.91. Any ideas? Did I not set up all the bands correctly?

Thanks and 73

Sounds like you have the other VFO on each band set to SSB. That would
change the default mode for that control to Mic Gain from CW Speed.

A single tap of A->B only copies frequency. A double tap of A->B copies
all other parameters (mode, filter etc.)

The mode on VFO B is USB or LSB (look at the mode indicator
in the LCD while holding the REV button). This is a side
effect of the K3's failure to copy the mode to VFO B on the
first tap of the A->B button.

In order to keep both VFOs on the same mode, you need to tap
A->B twice. The first tap copies only the frequency and the
second tap copies everything else (mode, filter settings,
antenna selection, etc.). The failure to copy mode has been
loudly debated several times.

Yes, that was the case. When I set up the band memories, I didn't
make sure both VFO's were properly set to CW. Since I normally have
the display set to real time clock mode, I didn't see the offending
USB indicator on VFO B.
Thanks for the many correct answers to my problem. That was very
quick.
A great list.
