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.
gqrx uses gr-osmosdr as source block, so it's identical.
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?).
Yes, the 'Gain' argument.
Also using the OSMOSDR block I still see an LO like
spike right in the
middle.
gqrx uses an internal DC offset correction algorithm, which you'd need
to implement in your flowgraph as well if you want to remove the
spike.
