Ed, No Spectrum Analyzer? You do have your SDR-IQ that will do that task on a narrowband segment. For a more detailed analysis take a look at G4AON's Simple Spectrum Analyzer at http://www.astromag.co.uk/ssa/. While the mixer should have a +7 dBm LO input, it should be usable with the XG3 0 dBm output (or build up an MMIC board with 7 dB gain.)
