I suggest that you join the Yahoo Group and post your question there. I
have virtually no AM broadcast QRM out here in the Santa Cruz Mountains. :)

I have one, thanks to a group purchase, with the TG. The spectrum
analyzer is quite nice. TG is a bit lame, but quite functional. TG
shortcomings are badly segmented sweep levels (jumps of a dB or two) and
a limited range of output voltage (-20dBm to 0 dBm). I'm told by another
engineer who bought in the same group that there's a "normalize"
function that gets around the segmentation issue. Last I heard,
Elecraft is likely to move to these units for production test. I share
your concerns re: support.
