[Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Chris Page]

Thanks to Don, Dan and Rich for their explanations of this problem.

Whilst noting what Don says about Logger 32 not sending the TX and RX 
information for each of the K2's VFOs, and that being the reason it 
will not work effectively, it cannot be the reason why it won't work 
with N1MM.  N1MM does send the TX and RX frequency information for 
each VFO, at least whenever the spot on the DX Cluster contains a TX 
and RX frequency, ie split operation on 40 and 80 metres CW.

N1MM does not have a Radio Debug window like Logger 32 and so I am 
unable to see what the actual command that is sent by N1MM to the K2.

By the way Rich, what logging program are you using?  It will be nice 
to know of one that doesn't cancel the split option on the K2.
