GNU Radio

I'm having trouble getting my SDR Play R2 to work correctly in GNU Radio. I have the API installed, I have gr-osmo installed .... it kind of works but not really. Sometimes, not all the time, but sometimes, I will see signals on the FFT, but unplugging the antenna makes no difference at all, its like its completely deaf. radio companion is detecting the SDRPlay but I can't get a usable signal from it.

Does anyone have some working parameters for gr-osmosdr ? Like what is the Antenna value ? A / B ?

Had some luck yesterday getting GQRX working, so I thought I'd try osmocom_fft. Seems OK as can be seen in the attached image. I tried a few options for the antenna, but haven't seen any difference.

I started it like 'osmocom_fft -a sdrplay -f 92.7M -W -A 2' There's a strong BBC Radio 4 transmission on 92.7MHz and '-W' is for the waterfall. It works with '-a soapy' too.

Where do you see that "radio companion is detecting the SDRPlay"?
