RPi + gPredict + RTL-SDR

[rushilkisoon]

Hi all,

I’ve been researching a bit into adding a SDR to my gPredict installation, specifically the RTL-SDR. I’ve come across SDR# (SDRSharp), but as far as I’m aware, it is a Windows based tweak, whilst the RPI is running RPi OS (Linux).

Is there a method to getting this working?

There’s a bit of info on running gpredict and gqrx and getting frequency control from gpredict to gqrx so it tracks doppler properly.
You should get all info needed from these two:

Thank you for all the info.
I set up GQRX, and used gPredict to control it via localhost.

Thanks for all the assistance!

The best way Ive found is to install SDR++. It has a rigctl server near the bottom of the left column. The default settings work great all you have to do is tick all 3 boxes Tuning, Recording, and Listen on Startup then click Start. Ive enclosed a pic to show the configuration in GPREDICT.
