[Discuss-gnuradio] USRP 1 Gnuradio

[Walter Barmak]

Good morning,

I have a USRP1 with 2 RFX1800, Ubuntu 11.04, Gnuradio 3.3.0 and
openbts2.6Mamou, stock clock (64MHz).

when I write:
usrp_fft.py -f 1800M 

a flat spectrum appears. which I think is correct, but when I write:
usrp_siggen.py -f 1.8G
the command prompts:
Press Enter to quit

Shouldn't a spectrum appear at 1.8GHz? What could the error be?
Thank you in advance,
Walter
