THAT is exactly it. I think I have a scenario where it happens:
You've done some stuff with usrp so that it and daughter card gets
loaded up.
You finish up, exit, rip out the power cable, plug in the power again
and the usrp USB gets re-registered.
Then, (with the verbose flag turned on) I see th

thanks for the solution, maybe i'll try with a different transformer
to shift the cutoff.

Actually, the differential amps are _cheaper_ than the transformers. I
went with the transformers because they
Gang - Yesterday I finally figured out how to create a rudimentary

see they actually (somewhat) work - at least it's something to work with
and play with parameters and see what happens. Currently using psk31
and gmsk signals,

Count me as interested, and actually wondering why your diff-amp solution
wasn't the default? I wonder what the cost differential between the AD8132

Speaking of, what is the
How is your RX mux register setup? If there are two ADC connected to the DDC,
then the second ADC will be the imaginary channel.

Hi,
I have a simple question on the USRP. When setting fpga digital
down-conversion frequency to zero via set_rx_freq method why do I get
nonzero (and changing) values in the imaginary channel? Seems like
these should all be zero since sin(0)==0 ??
Thanks,
Viktor

PortAudio looks interesting because it has a Windows port too. Anyone
have any experience with it? Interested in
FWIW the version of jack that runs on OSX appears to have
matured quite a bit. PortAudio also has an OSX version, but
given a choice, I'd bet more on jack.

I was under the impression that OS X offered OSS (Open Sound System)
emulation, in which case our gr-audio-oss module would work.
Can someone confirm this?
If not, is there a good reference online about sound programming for OS X?
