[Elecraft] Flex SDR panadapter

[Ron D'Eau Claire]

If you don't have a second receiver in the shack to listen for yourself, how
about asking someone else to listen for the spur?

If you use a local receiver, be sure it has a dummy load connected and the
main signal on the intended frequency is NOT overloading it - a maximum
reading of 10 or 20 dB over S-9 is a good top limit. Too much RF can produce
lots of false signals in the receiver.

Maybe, but consider that some SDR pan adapters exhibit false images if not
properly 'set up'.  I can't think of a better description for it.
