Is anyone using the USRP with MacOSX? I have followed the threads
regarding issues getting gnuradio up and running on OSX, but have not
seen anything specific to the USRP.

Can someone give a general overview/recap of the current OS X status?
I have done my best to follow the list traffic and search the
archives.
What are the general steps to compile? Are all relavent patches, etc. in CVS?
USRP is working but at slow speeds?
Audio support is under development but n
I followed your instructions with absolute success. Thank you for the

I got an error building the DarwinPorts sdcc and after I added an
include to get sdcc to compile, sdcc errored out while building USRP.
Are there any nonstandard procedures there?

FWIW, to get SDCC to compile and link the USRP I had to set in the environment:
SDCC_LIB=/opt/local/share/sdcc/lib/
SDCC_INCLUDE=/opt/local/share/sdcc/include/

Currently in response to a message in a message queue, I am opening a file

keep this file sink open until I receive another message in the queue to

Ideally, the capture would

We are successfully using the PFB filterbank to channelize 1-6mhz into a

In one application, we have 25K channels which are then resampled using PFB

In this case, we may have 20-40 ports "active"

I'm currently trying to extract a relatively small number of narrowband

My RFX900 has stopped transmitting. Nothing else has changed and it still

Anything I can look at short of ordering a new board?

Finally having all the pieces in place I need, I want to use the new
GMSK code to decode an EDACS trunked radio control channel.
Given my rudimentary knowledge on the topic (and gnuradio in general)
