Gary,
I think -110 dBm sensitivity is marginal for RFI detective work, especially
while working with low gain loops when trying to localize switch-mode
interference. Some of the loop preamps I've used produce much more
gain/noise than signal. For the money, I would look at one of the new,
compact SDR receivers that contain a basic spectrum analyzer function.
These will measure a -140 dBm noise floor. Of course, you don't have the
ability to change resolution bandwidth as one would have with a true
spectrum analyzer but that's perfectly adequate for RFI work.

This might be a useful RFI fighting tool. Probably only a matter of
time before the price comes down.
