Thanks Gwyn,
Fascinating plots. I just lowered my RF output power to -13 dBm (50 microwatts)....i.e. effective 1527 UTC on 5 October 2021.  I've attached a screen shot for the past 24 hours at -10 dBm (100 microwatts), with 9 stations still able to spot me.  By the way, the antenna I'm using is quite simple - just an EFHW cut for the 40-10 meter bands, horizontal at about 12 ft. above ground level.  We'll see what happens next.
