[Elecraft] Using fldigi with KX3 and KXPA100

[John Pitz]

I have a KX3 and a KXPA100,  When I have the two connected as per the
manual with the KXPA100 off, fldigi can connect to the KX3.  As soon as
I turn on the KXPA100 fldigi can no longer communicate with the KX3.
How do I get fldigi to communicate to the KX3 with the KXPA100 powered
up?  It seems that this should be a lot easier than what I am making it.

My setup is:
A laptop running Linux mint
KX3 
KXPA100
fldigi v3.23.03 using Hamlib

I can connect without any trouble with both the KX3 utility and the
KXPA100 utility.  I was under the impression that both units used
different command sets and that the KXPA100 would forward anything it
does not recognize on to the KX3.  

Incidentally, I did try powering on the amp, then connecting with the
KX3 utility, then closing the KX3 utility and launching fldigi.  

It would be really helpful for my education on the digital modes to be
able to see the frequency I am using on the waterfall display.
