RSP1A No Waterfall Help

SatNOGS Software
1

New install within Debian 10 virtual machine using RSP1A. No waterfall and RuntimeError shown below. RSP1A runs fine in CubicSDR. I’ve tried both the v2 and v3 of the SDRPlay API, searchd through troubleshooting and referenced other’s RSP1A settings. I need help understanding possible causes. Many thanks!

I think is the sample rate problem.

Thank you Michel for responding. I have tried other sample rates, but still no waterfall. The sample rate I used is a valid rate for the RSP1A. The error message ranges seem to be audio sample rates instead of RX sample rates, so the error message doesn’t seem to match the parameter it says is wrong. I saw a similar post for an RTLSDR, but it seemed to be related to not recognizing the RTLSDR. So it seems like this message is more a symptom and not the root cause.

I’d check PATH’s in satnogs-setup as well as the permissions on the various data directories.

I will do that and report back what I find and results. Thanks!

I’ve not been able to find any path or permission issues. I did a fresh install in another VM making sure to install API 3 from sdrplay. It looks like it is maybe an issue with compatibility with API 3? I can find the RSP1A fine with SoapySDRUtil and execute a loop test, but satnogs_fsk.py errors with : RuntimeError: SoapySDR::Device::make() no match

SoapySDRUtil --args=“driver=sdrplay” --direction=RX --rate=1e6

If I change --soapy-rx-device to sdrplay I get an error of unsupported sample rate which looks like it’s a wrong driver issue:

satnogs_fsk.py --soapy-rx-device=“sdrplay” --rx-freq=444000000 --file-path=./audio-out.ogg --waterfall-file-path=./waterfall.dat --samp-rate-rx=1e6 --antenna=RX

RuntimeError: soapy::source: Unsupported sample rate (1000000.000000). Rate must be in the range [48000.000000, 48000.000000]

So what is satnogs_fsk.py passing or getting from soapy that it’s not happy about?

I have spent hours working on this with still no success. Either I am overlooking something pretty obvious or there is a bug in the desktop implementation. I am running Debian 10.

To summarize: SoapySDRUtil --probe returns the correct information so the RSP1A is installed correctly with API 3 driver from SdrPlay, but manual tests with satnogs_fsk.py returns RuntimeError: SoapySDR::Device::make() no match.

Even though I have installed SoapySDRPlay from SdrPlay, it’s as if satnogs_fsk is still using old soapy. I have not been able to figure out what path satnogs is calling soapy from, so maybe I have to change the install path of SoapySDRPlay?
