Hello All:

All three receiving programs in gnuradio-examples/python/usrp are working fine 
with my new usrp. The ones tested are usrp_oscope.py, usrp_fft_simple.py & 

The fragility I obseverved yesterday is in my computer setup, and not the 
gnuradio software.

I can setup a signal generator with both usrp_fft_simple.py and usro_ft.py and 
see a modest 1-2 Mhz signal down to -70dBm. If I phase modulate the signal 
generator, I can see the sidebands in the fft display on the computer screen.

The fft program ran all night long and this morning were still displaying the 
spectrum just fine.

Kudos to Matt & Eric for a solid piece of hardware and software.

p.s. The next step is an in depth study of the classes beginning with 
usrp_basic and its subclasses usrp_basic_rx, usrp_basic_tx, usrp_standard, 
usrp_standard_tx and usrp_standard_rx, all of which are in usrp/host/lib.

p.p.s I guess I will need to setup an audio device on my test computer soon.

p.p.p.s I also guess I will need to bring out the IF on one of my ham radios 
also soon.
