Hi Joe
Of the two options you've outlined, I'd definitely recommend the WBX instead of LF
or Basic RX. If you later decide to use the R-7000 you could hook up a hamitup or other
converter. (Note, you'll need to perform the R-7000 AGC mod). With the WBX it will
open up a lot of things in the spectrum that would otherwise pass you by, and the full
stature of the USRP would otherwise be wasted on a narrowband source...
