I’m a new user of SatNogs, still testing. I want to replace the cheap NooElec SDR dongle for a more performing one (RSP2).
As said briefly in the wiki, we have to download and install the driver from the SDRPlay WEB services to the RPI in order to use one of their RSPx dongle.
Can some one explain me how to do so : detailed series of instructions since I’m little ‘rusted’ with linux commands.
Such informations worth certainly to be added to the wiki.
Many thanks.

Add me to the list of users wanting instructions on how to do this. I’ve tried adding the sdrplay drivers to the Satnogs Rpi image and adding the Satnogs client to the SDRPlay Rpi image. Neither path worked. The RTL-SDR dongle I have just isn’t up to the job compared to my other SDR’s (FuncubePro+ in particular).
I’ve been copying telemetry daily from the Huskysat using the Foxtelem software in windows with my Funcube. The same antenna system with the RTL-SDR on Satnogs shows almost nothing getting decoded.
Please add me also to the list of potential SDRPlay users.
I observe the satellites with RSP2 (SDRPlay) and SDRuno a very nice program, and they are received much better than what I can get with genuine RTL-SDRs.

Same here…Another user waiting for change to my RSP1
For the RSP1A this is a working configuration:
“satnogs_antenna”: “RX”,
“satnogs_rf_gain”: “34”,
“satnogs_rx_bandwidth”: “600e3”,
“satnogs_rx_samp_rate”: “2e6”,
“satnogs_soapy_rx_device”: “driver=sdrplay”,
Requires more memory than a 1 GByte RPi 3B. A 4 GByte RPi 4B works ok.
I’m surprised using the antenna of “RX” works.
Could you post the output of SoapySDRUtil --probe="driver=sdrplay" so we can see what the antenna names are?

I noticed that the latest logs (journalctl -f -u satnogs-client.service) not only complain about wrong values but also list the valid ones.

I guess there’s been an update to the client!
OK, I didn’t realise the RSP1A only had one antenna port! That would explain it 
I’d be interested if other SDRPlay users with different models could post their output, so we can build up a list of valid antenna options.
This are the versions in my installation:
SDRplay_RSP_API-ARM32-3.07.2.run
Module found: /usr/local/lib/SoapySDR/modules0.7/libsdrPlaySupport.so (0.3.0-3381015)
The API documentation at https://www.sdrplay.com/docs/SDRplay_API_Specification_v3.06.pdf doesn’t have antenna names, just enumerations, so they should be in the SoapySDR source. (Found them in Settings.cpp).
For info i packaged the SDRPlay 3.07 drivers as .deb packages for PC and raspberry (and even aarch64):
The new 3.07 driver supports SdrPlay Duo and Dx.

Hi fjkraan…
thanks for your settup info…
can you give us your RFGR and IFGR values? ve2dsk
IFGR gain range: [20, 59] dB
RFGR gain range: [0, 9] dB
This setup has been working for me.
Rgds
Karl.
