Dear LF Group,
I had a nice QRSS contact with RN6BN last night, with "O" reports both
ways, and 'BN was a clearly audible S3 signal at my location. Several
others stations were also active, including IK2PII who I don't think I have
seen before.
It is interesting how there seems to be a division between paths up to
about 3000km, where good conditions are fairly commonplace during darkness
hours, and those over about 5000km, where good conditions are much rarer
and change very rapidly. Both must surely involve mostly sky-wave
propagation, but the longer distance paths just evaporate whenever there is
a whiff of solar activity. The shorter paths on the other hand seem much
less affected. So my guess is there is a change in propagation modes
somewhere in the region of 4000km - I suppose CT1DRPs beacon signals to the
eastern US are on the borderline, so make for an interesting comparison.
