Hello,

I’m trying to receive a 6 MHz TV signal. What frequency should I set  
my UHD: USRP Source in the GRC?  
Thanks.

Hello Gerome,

to the center frequency of your TV channel, probably. You’d set the  
sampling rate to 6MHz, or something higher, depending on what bandwidth  
you want to observe and which sampling rates your USRP support.

Greetings,

Marcus
