Hi Folks, I have analysed the logic of the anomaly in this report These forms of anomaly - though rare – are something that we may have to watch for manually … Hence “grit and bare”.

Do NOT consider this a “knock” … it is just a report ! I am recording approximately 1 serious “false decode” every 12 hours on average. Note that I am using “AP” mode: i.e. 200514_032030 18.100 Tx FT8 0 0.0 700 CQ VK3VM QF11 200514_032045 18.100 Rx FT8 -16 0.3 763 JA2ATE N4QS RR73 200514_032045 18.100 Rx FT8 -24 2.4 2463 VK3VM 1P4ZBI/R R JH60 ? a2 200514_032100 18.100 Tx FT8 0 0.0 700 1P4ZBI/R VK3VM RR73 200514_032115 18.100 Rx FT8 -13 0.3 763 JA2ATE N4QS RR73 200514_032115 18.100 Rx FT8 -15 0.1 2016 JF7ELG YB0AA -15 This responded with an attempt to log. I now have recorders on and hopefully can catch a snippet of the audio stream for analysis. Perhaps a “catch” for such grossly out-of-sequence false decodes may be needed? 73 Steve I VK3VM / VK3SIR
