The ones at 710, 830, and 950 are exactly 120 Hz apart - 2x the US line frequency. The 350 and is 6x60 Hz away from 710 (and exact multiples of 120 Hz from all of the others as well).
You've got 950 Hz (the presumed fundamental), 950 - 120, 950 - 240, and 950 - 600. Missing would be the subharmonics between 350 and 710 Hz (. The second pair are almost 360 Hz apart. It sounds like there's some AC mixing going on. -- David Tiller Sr. Architect/Lead Consultant | CapTech (804) 304-0638 | dtil...@captechconsulting.com<mailto:dtil...@captechconsulting.com> On Jul 13, 2019, at 2:29 PM, Bill Barrett <w2pky...@gmail.com<mailto:w2pky...@gmail.com>> wrote: Hello Reino- 190708_224015 50.313 Rx FT8 -24 0.3 350 WC4H W4I R-13 190708_224015 50.313 Rx FT8 -12 0.3 710 WC4H W4I R-13 190708_224015 50.313 Rx FT8 -7 0.3 830 WC4H W4I R-13 190708_224015 50.313 Rx FT8 17 0.3 950 WC4H W4I R-13 190708_224045 50.313 Rx FT8 -24 0.3 350 WC4H W4I 73 190708_224045 50.313 Rx FT8 -14 0.3 709 WC4H W4I 73 Thanks for the tip.

If so what was the frequency difference between those sub-harmonics? 73, Reino oh3ma _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net<mailto:wsjt-devel@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net<mailto:wsjt-devel@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/wsjt-devel
