Hi,
I need to align the audio switching network of my ham radio repeater db0fue,
and it would be nice to have some GRC GUI element that allows me to switch

I guess finding it out myself probably would take too long :) Jus
Question 3: AES is indeed a common system for voice encryption, widely used
for example in US police / public safety radios (APCO25 standard). Older
systems used often DES, but not with a neat linear predictive voice codec,
but just a CVSD digitizer, DES box and FSK radio link (Motorola SECURENET).
I really would recommend some x86 tablet; I am using gnuradio on a MS Surface
pro, and this is really fun!

Hi,
I am using bladeRF with gr-osmosdr, gnuradio 3.7 and gqrx, so far a fine
radio. One thing, when using gqrx...I am limited to USB2.0 at the moment, so
I use a sampling rate of 8 Ms/s, and in this mode I have big problems with
images from the neighbour frequencies that are still within the 26 MH
TCXO needs some alignment before it could be used for OpenBTS; but as
this is not yet supported, this is not very urgent for now.
Ralph.

Hi,
Are there any out here with experience in getting bladeRF being usable with
gnuradio/grc? So far I followed the usual steps, bladerf and gr-osmosdr
compiled, but as documentation is being far from getting finished, I only
reach the point of loading manually the FPGA image, nothing more :(

Yep, brute forced it should be possible :-) Not really the same like with UMTS
or LTE...

AFAIK.
I would rate GPS as invisible, with normal receiver technology. They are
using a low bitrate, spreaded over a very large frequency range. The only
way to "see" something should be correlating and decoding the stuff.

Hi,
At the moment I am stuck with trying to install OpenBTS in an VMware
environment, while the "real thing" is a Windows 8 PC. Everything installs
and compiles just fine, the USRP gets set to the assigned frequency, but
then the whole thing hangs with strange messages. I have similar effects

Hmm, it _was_ a new copy, last one one hour ago...or any changes since then?

Aah, gras still is 3.6, no 3.7 support? Or does 3.7 need an additional
option?

Hi,
Will it be possible to install gras into a system that already has an
installed gnuradio version, latest 3.7 build, or is it recommended to remove
the single gr 3.7 installation before building gras? If the latter is
recommended, will I run into trouble with other tools that depend on
gnuradio
