Hi,
this series of patches add BW setting support for R820T and interface to
set BW explicitly. This work is partialy based on some patches flying
around namely Alexander Kurpiers. Testing have been done for some
dongles at it looks good except for rally narrow BW setting.
No testing of BW setting have been performed for other RF frontends i
have only R820T now.

I would like to humbly request support for hackrf antenna power in gr-osmosdr. At runtime preferably, or at least an init string flag to control it
(hackrf=0,antenna_power=1 for example). The function call seems to be hackrf_set_antenna_enable() but it's not exposed in gr-osmosdr as far as I can tell.
I have some dev experience (but not in C) but I'm falling short trying to understand the code and add the feature myself. If someone wants to provide some "ELI5" guidance I'll be happy to give it another go.
Having this feature would open up the powered antenna feature to users of gr-osmosdr such as gnuradio, gqrx, and the list goes on (big win!)

Thanks!

This is rework of previous post of patches for setting BW on R820T
tunners. It contains only minor cleantups (fix grammar) and add function
for getting BW.
The one question remains whatever to keep or not BW setting support for
really narrow bandwidth values. They does have a bit blurry edges and
for unexperienced users can cause a bit of troubles in other hand for
someone who knows what to do can be still usefull.

Moin,
what bandwiidth is needed for sdr_tcp? Does it depend on the signal
bandwiidth like CW or stereo fm? I wonder if it will work on a Respberry
Pi B+ with 700kBit/s uplink.
Thanks for any hint

Hi,
I had a problem with rtlsdr_cancel_async.
I find this fork on github that solve my problem
https://github.com/pabigot/rtl-sdr
nice ..
And then realize that there are 46 forks of the rtl-sdr on github....
I know that's how github works , but is there somewhere an effort to
merge the best of these mods ?
It doesn't seems to be the case on github, but perhaps elsewhere ?
Hi all,
anyone could tell me how to compile rtl-sdr on windows using cygwin?
i have all libs but i seem not to get any dlls and programs back.
used the normal cmake and the method using a configure script.
greetings,
simon
