Hi Tom,
The image nulling procedure is built in the PX3. I did not run it in
order not to alter these settings for the KX3 - I merely wanted to
indicate that is is possible. I have the necessary signal generator to
do so, that wasn't the reason not doing this...

I did, it works
With a Softrock-RX for 30 metres. The LO is an xtal on 40.5 MHz that
produces 10.125 MHz and that shows on the PX3 as 0Hz.
The real problem comes with the need to recalibrate te I/Q phase and
amplitude in order to have a good image rejection.
On -25 kHz I see the DDK9
Hi Yes but can't you calibrate this out using a signal generator and the px3
calibration facility?
Of course, it appears that the iq correction operates on only a single
frequency and does not do frequency based corrections. I could be wrong about
this though.
One way to tell is to put a
Hi
It would not work properly as is. I think one would need to send information to
the px3 via the serial port to establish the centre frequency, markers, and
respond to qsy''s.etc. as well as react to requests coming from the px3.
Assuming these are standard api type commands it could be a
Has anyone used the PX3 Panadapter with a receiver that has I/Q outputs
other than the KX3 such as the Softrock or ??
