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. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Richard Fjeld Sent: Friday, September 23, 2016 11:07 PM To: [email protected] Subject: Re: [Elecraft] Flex SDR panadapter 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.
