Neil,
I would expect up to 300 km range using 100W and a modest antenna. See 
the attached plot. Stations ZL2AFP and ZL2EE are co-sited (same station, 
two consecutive days). These are mostly ping responses measured from my 
interrogating his station.

What we find interesting is that the downward fade in the morning has a 
different (and steeper) slope than the evening rise in signal. This is 
completely consistent.

ZL2AFP and I are 330 km apart (that's 206 old-fashioned miles). We both 
run the same 100 W home-brew transmitter design. His site and antenna is 
a little better than mine. We can QSO on 474 kHz WSQCall 24/7.

The plot was generated by WSQPlot from the WSQCall Heard Log. Times are 
local.

73,
Murray ZL1BPU
