Have you been following this thread and mention of TI DSPs, other low bitrate
codecs that run on TI DSPs (MELPe), etc?

Hello,
The DV Dongle device uses open source firmware. It appears the manufacturer is
not following the provisions of the GNU license a
I am using two TVRx modules on the same motherboard to write a 1 second
sample every minute for 30mins. theoretically I should have 60 sample sets,
collectively.
I am able to write the first sample set succesfully but all writes after
that fail!
Please take a moment to look at what I may be doing

Hi All,
I am using usrp_spectrum_sense.py 1400M 2000M -F 512 -d 16 --tune-delay 1e-3
--dwell-delay 10e-3 to sense the spectrum.
In main_loop(tb), I print m.center_freq and m.data.
freq_step = 0.75 * usrp_rate=0.75*(64M/16)=3M. So m.center_freq[0]=1401.5M,
m.data[0]~m.data[511] are 512 bins co
