I'm about 25 km LOS from W7RN. W7RN is 30 over S9 here on 160, 10 over
on 80, about S7 on 40 anytime. I can barely see it on the P3 [and it's
QRK2 in the noise on the headphones] on 20, and missing above 20. K2RD
in SW Reno is a bit closer, but the same prevails for the ground wave
for Ira.

confusing groundwave (usually up to 25 miles) with NVIS.
Yes, AND groundwave weakens drastically with increasing frequency.
With average soil, a station operating on 550 kHz will be 21 dB
stronger at 100 miles than a station running the same power than one
operating on 1600 kHz, assuming both are using a single quarter wave
tower.
