Beyond voice

So in this new world of Satellite operation, I've been slowly, ever so slowly, catching up on digital technology, software, satelllite telemetry, and working other modes.

For some reason, I still want to hit my thumb with a hammer, so I stay off the simple things and jump right into what, for me, is the most complicated of approaches.

Sure, a grade school girl can, with the help of her dad, work all the FM satellites that pass on the east coast, but I'd like try to understand the world of SDR, digital modes, rig control, and yes eventually satellite antenna control, all via a Nextbook 8" win10 tablet if possible.

So far, I was able to try two SDR receivers:
  • The RTL-SDR dongle and
  • The SDRPlay SDR receiver

Both have their upsides.

The RTL-SDR/SDR# and WXtoIMG combo seems to consume fewer CPU cycles than the
SDRPlay/HDSDR/WXtoIMG combo for receiving satellite images. However, I seem to more consistently get decent images out of SDR# than HDSDR. Haven't quite figured that out yet.

A recent and decent image I received is from NOAA-19:





an earlier image that was a little less clear, from NOAA-18:
