R820T and Gnuradio

I have gnuradio running with the R820D DVB. Latest GQRX has the nice rf gain inside which REALLY helps. Has this been merged over to gr-osmosdr ? I recompiled probably just a few days, both from source. I'm trying to figure out how to set gain from within gnuradio (is there a argument I can pass the device in the source block?). I've been successfully decoding AFSK1200 APRS using gqrx and am trying to figure out how to set up an ultracheap iGate for APRS, maybe with gnuradio in the mix. Also using the OSMOSDR block I still see an LO like spike right in the middle. Here's my output starting GQRX. Interesting it's saying gr-osmosdr supported device types... ron@tripel:~$ startGqrx.sh ron@tripel:~$ gr-osmosdr supported device types: file fcd rtl rtl_tcp uhd gr-osmosdr supported device types: file fcd rtl rtl_tcp uhd Using device #0: Generic RTL2832U (e.g. hama nano) Found Rafael Micro R820T tuner TIA! -Ron / KB1UMH
