How to set the antenna to use?

[BikerJohn66]

For the dumpHFDL program I use a SDRdx via SoapySDR on Raspberry Pi 4 that's running the bookworm operating system. The SoapySDRUtil --probe"driver=sdrplay" result is:

How can I set the "Antenna C" as the one to be used? I tried all variations I could think of of driver=sdrplay,antenna="Atenna C" but the result is the same:

driver=sdrplay,ant=Antenna C: center frequency set to 3814.000 kHz driver=sdrplay,ant=Antenna C: frequency correction set to 0.00 ppm driver=sdrplay,ant=Antenna C: auto gain enabled driver=sdrplay,ant=Antenna C: using antenna Antenna A driver=sdrplay,ant=Antenna C: using native sample format CS16 (full_scale: 32767.000)

Thanks in advance!

Isn't the antenna arg antenna and not ant? If you found ant mentioned somewhere that should be corrected.

Just found it by accident. driver=sdrplay --antenna="Antenna C". Thank you very much for your help!
