Re: [Discuss-gnuradio] Broken WBX?

[Matt Ettus]

Mike,

Doe your USRP have a serial number below 500?  I know you've been a 
longtime user, so yours may be that old.  If so, the WBX won't work for 
you since USRPs under #500 do not send a clock to the daughterboard, and 
the WBX needs one.

Also, note that in the following command:

 WBX (RX antenna): ./usrp_fft.py -R A -f 940.2M -d 64 -g 35 -A RX

it should read "-A RX2" on the end.
