And of course, 2M WSPR helps you also figure out if tropo propagation is occurring between any two (or more) given points.
During the Spring FD yesterday afternoon, I heard ZL1IU weakly on 144.170 , around S0-1, and he knew someone was calling when I called him but he didn't get my callsign.
The guys portable at Mt Mowbullan (the old VK4RTT site) reported him at something like S7 given their height advantage, so probably tropo.
Was it confirmed as 2M Es or tropo ? Don't know - but I worked Alan ZL1RQ on 6M SSB (along with VK1, 2, 3 and 5s) via Es earlier in the day so it could have been either.
I was reminded again about one of the peculiarities of Es on 6M too. I could barely hear a given VK3 or VK5 while others 70-100KM north of me were giving good signal reports. Other times the southern signals were strong with me and those to the north of me weren't working anything : Narrow-ish and changing skip zone areas.
