Re: [Discuss-gnuradio] RTL2832 ($20 USB SDR) support now in gr-baz

[Balint Seeber]

Hi Rafael,

The intention for upstream submission is certainly there, however time is
not quite... hopefully soon.

Some blocks need optimisation, cleaning and re-styling - if anyone wishes to
help by sending a patch, that would be wonderful (I just received my first a
little while ago!).

Re: getting the dongle, I happened to get lucky on eBay. I can only suggest
to keep searching! Good luck.

Kind regards,
Balint
