[Elecraft] N1MM, KX3, and KXPA100

[Ryan Noguchi]

I use N1MM Logger+ with my KX3 and KXPA100. Never had the issue you describe with my equipment. 
My first suggestion would be to make sure you're using the latest firmware, especially on the KXPA100. The firmware on my club's KX3 and KXPA100 were horrendously out of date, resulting in all kinds of trouble with the tuner and PA until I updated the firmware, including a similar issue to what you described independent of N1MM Logger+.

I've borrowed a KX3 and KXPA100 for the 7QP, going mobile.
I plan to use N1MM for logging, keying, and frequency control.

I can get N1MM to talk to the KX3.
I can get N1MM to talk to the KX3 through the KXPA100 daisy chained
serial connection.

However, whenever I talk through to the KX3 through the KXPA100,
the PA gets turned off. If I turn it back on, it gets turned back off.

I can't find any clues in the manuals and I can't find any clues on a search
of the net.

Someone must be using N1MM to talk to the KX3/KXPA100 combo.
Can someone give me any ideas of what I am doing wrong?

cheers
