[Elecraft] KX3 IQ using NaP3

Tue Dec 24 09:23:29 EST 2013

Sorry Ariel, Hit the wrong button...Should of course have sent it to the 
list instead of you.

I tried NaP3 but I'm afarid I am too much a HDSDR type so I get stuck on 
using PowerSDR and it's derivatives.

I tried NaP3 with my simple SoftRock mixer on 30 meters and found that 
indeed it automatically calibrates the I/Q phase and amplitude and does 
that quite fast. Using the second VFO I could receive signals but trying 
to tune the first one does not work, it stays put on 0 Hz. I can choose 
all sorts of transceivers but not the simple I/Q mixers, as in HDSDR. I 
have HDSDR working with my KX3 and will hook it up to NaP3 and post my 
findings.

To Al:

One of the most important things is to use an audio cable with an 1:1 
isolation transformer between the KX3 and the computer/soundcard input. 
Much of the noise you see stems from all sorts of ground loops.

To be continued...

Peter
