Noted this evening that a few calls are duplicated at different frequencies. See below. Not seen this problem before, but setup here seems ok. The strongest signal in each group is clearly the the fundamental (so to speak) Not every station is being duplicated. The 4 calls listed seem to be most common, but even then not every call. Setup here is Flex3000 with HP6735S laptop and 9mtr vertical at 3mtrs, WSPR 2.20 and PowerSDR v2.20RC2. Any suggestions or observations appreciated.
