Re: [Discuss-gnuradio] What impedance are the wires and antenna?

I will try and get a hold of the TVRX board, but in the meantime, are there any workarounds? Is this because the BasicRX doesn't have a filter and whatnot in it to specifically target the radio frequencies?

It will work more-or-less, but it's not really the daughterboard to
use to receive broadcast FM.  The TVRX is a much better choice.

The USRP1 samples at 64MHz, which means that when using the Basic Rx
to attempt to receive the broadcast FM band, you'll be "bandpass
sampling" and there'll be a fold at 96MHz (3/2 fs), right in the
middle of the broadcast FM band.  You won't be able to separate out
96M-f from 96M+f for any frequency offset f.
