[Elecraft] [K3] KAT3 not functioning on 6m

[Bill Coleman]

OK, I figured this out, sort of.

Every time I’ve had trouble with the KAT3 not tuning, the K3 has been in split mode.

By taking the K3 out of split mode, I’m able to turn on 6m correctly.

Oddly, though, when I return to split mode, it still works. 

I’m not sure why I see this issue, but I’m glad I can work around it.

Split mode is often configured due to the WSJT-X settings, depending on the frequencies used.
