Early in the contest I made a QSO with RT6A, with 410 mW on 20 meter. When I heard RT6A again on the same band, about an hour later, the band had changed, so the signal was very strong, about 20 dB over S9.
So I decided to try to make a dupe with a power of 4.1 mW, using the FT-817 and a homebrew attenuator.
I expected to get the usual ”sri QSO B4 TU” but to my surprise, I received an immediate response. I logged the exchange and went to the next station on the band.
After working two stations (K5 and K3 both with 1 Watt), when I was turning over the band, I heard RT6A again.
