Unable to change center frequency w/ GQRX

Open alphafox02 opened this issue 2 years ago • 1 comments

While doing a quick test on 22.04 w/ Soapy8 and latest GQRX, I added the SoapySpyServer. Running Airspy's SpyServer on the local host with either the RTLSDR or Airspy R2 I can connect to the SpyServer with GQRX using a blank entry for sample rate and a argument string of soapy=0,driver=spyserver,host=0.0.0.0,port=5555

However, after connecting the FFT and Waterfall is locked on the center freq around about 90 something MHz. I am unable to change the center freq and doing so just changes the GQRX GUI frequency range, not the actual spy server freq. I can raise/lowser gain and demod with great results on FM.

I can then disconnect from the spy server and load up SDR++ and actually use it to change the freq. Is it expected that from GQRX or other Soapy front ends that the user can change the frequency when it's not locked from doing so in the spy server config?

Just a follow up to say that within GNU Radio itself, using the GR-RDS flowgraph altered with a custom soapy source block and basically the same settings as GQRX, I'm able to change the frequency using the QT Gui setup.
