[hpsdr] Saving panadapter data?

[Warren C. Pratt]

Hi Alf,

I think you'd have to do some coding to get the data into a file.  (At least
I'm not thinking of another way at the moment.)

The source code for the latest mRX can be found here:
<http://svn.tapr.org/repos_sdr_hpsdr/trunk/W5WC/PowerSDR_HPSDR_mRX> 

The spectrum processing code (generates both panadapter and spectrum data)
is packaged in the specHPSDR.dll; so look for the specHPSDR project.  I
wrote the code.  Unfortunately, I have too much going on right now to be
able to add this capability; however, I'm happy to answer some basic
questions if you want to give it a try.

A few quick thoughts:
**You can obviously get pre-averaged or post-averaged data.
**You can get data at the FFT resolution or data at the screen resolution.
**I recall adding a SnapSpectrum function to get raw FFT output to be used
for the calibration procedures--that might help.
**I'd suggest that any file-writing you do be done on a new thread.

Sorry I can't take this on at the moment.

Greetings,

Is there a way to get the actual values making up the panadapter display?
I use my rigs mostly as adjuncts to my test equipment lab and frequently
need to compare panadapter plots. Making screen plots and then visually
overlaying them is tedious.
I know I can get the raw data stream, but regenerating the display is too
much like hard work. For an added bonus I'd like it to work with the
spectrum display as well as the panadapter, and have both the raw and
averaged data.
I can already get the scale info via CAT.
I am currently using mRX v3.0.11 with my Hermes, and 2Rx v2.2.8 with my
Ozy/Merc, (I realise there are more recent versions).

Hunting around the repository has not revealed the source code, else I would
have had a go at this myself.
Does anyone have suggestions for how I might do this?
