It was interesting to see the delay from when 160m closed in the morning… to 80m CW
closing… and then finally 75m SSB. The 10%+ difference in frequency between 80m CW and
75m SSB was obvious.
Thanks for posting about this, Eric. Far too many DXers, contesters, and
DXpeditioners fail to have a clue about enhanced propagation on the
daylight side of the terminators -- that is, both sunrise and sunset.
On 160, it's typically 30-40 minutes, about an hour on 80, about 2 hours
on 40. I've lost a LOT of shots at difficult Qs with expeditions who
abandoned a band at the first sign of sun in the morning, or to go to
the band before sunset.
