PlutoSDR

It is possible to swap RTL-SDR to PlutoSDR, but this requires some manual steps.

Install additional software

PlutoSDR is operating on too high sample rate. In order to work on smaller rates, special software is needed:

sudo apt-get update
sudo apt-get install plutosdr

Configure

Configuration is manual. Edit it at: ~/.r2cloud and add the following line:

satellites.sdr=plutosdr

This will override default sdr. Other parameters are:

sdr.devices=0
sdr.device.0.minFrequency=100000000
sdr.device.0.maxFrequency=1700000000
sdr.device.0.ppm=0
# it's better to change to 0.0 (auto) for PlutoSDR
sdr.device.0.rtlsdr.gain=45
sdr.device.0.rotctrld.hostname=127.0.0.1
sdr.device.0.rotctrld.port=4533
sdr.device.0.rotctrld.timeout=10000
sdr.device.0.rotator.tolerance=5
sdr.device.0.rotator.cycleMillis=1000
sdr.device.0.rotator.enabled=false

Results

The smallest possible sample rate for plutosdr is 580ksps. This is still more than 240ksps available in RTL-SDR. This will affect application performance. Spectograms and observations will be processed a bit longer.
