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.

Paul, W9AC

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