A little OT, but related to the K2. I installed the IF Buffer amp in my
K2 and feed it to an RSP2 and run HDSDR on the PC. When running HDSDR in
IF mode, it makes for a very nice panadapter for the K2. I haven't
messed with this for awhile and installed the latest version of HDSDR
and was able to come up with the offsets necessary per mode for the
point and click to be very accurate on the spectrum.
An issue I'm having is that I would like to use the spectrum display in
a "fixed tune mode" fashion similar to the P3. I.e. I set up the
waterfall and spectrum windows for a 300KHz width for looking at 40m and
would like to point and click on the signal of interest without the
spectrum moving or sliding to the signal position I just selected. As it
stands now, wherever the current signal selected is displayed in the
spectrum, as soon as you select another signal, the entire spectrum
moves to put the newly selected signal in the same location on the
screen.
I am able to get this function if I take the audio from HDSDR and use it
with independent tuning from the K2. So, I'm guessing that the reset of
the spectrum screen is due to linking the tuning with the K2 via OmniRig
- but I'm not sure.
I could swear I had this ability in the past, but it may never have been
the case. I reinstalled an older version of HDSDR and it acted exactly
the same. So, I'm wondering if anyone else has been down this road and
knows of a trick that I have not found yet for doing fixed mode tuning
while using HDSDR in IF mode synced to the K2.
Even if this is not possible, this configuration makes for a fine
panadapter for a K2 with the IF amp sold by DX Engineering. It is Jack
Smith's, K8ZOA (SK) design and works nicely.
