[Elecraft] K3 cross-band split

This is not an N1MM Logger issue; the same thing happens if you try to 
do this (cross-band split) from the front panel.

The K3 does not support cross-band split using the SPLIT function. That 
is, you cannot transmit from VFO B when the two VFOs are on different 
bands. With VFO IND set to "Yes", you can set the subRX to receive on a 
different band from VFO A, so in that sense you can operate cross-band 
(listening on VFO B and transmitting from VFO A), but you cannot operate 
the K3 in the reverse orientation (listening on VFO A and transmitting 
from VFO B). That is what the "SPL N/A" message on the K3's display is 
telling you.

Bottom line: if you want to operate cross-band split with the K3, you 
have to put the transmit frequency in VFO A. Dave AB7E has described a 
way to do this from N1MM Logger - see
