"Closed" Bands

It's early evening, and everyone seems to have deserted 10 metres down to 17 metres. At least in the portions of the bands I inhabit. TG9AHM was calling CQ in PSK31 vainly on 10 metres. I tried him (even upped the power to 70 watts once...) but he can't hear me. A station in the Southern States popped up as hearing me on pskreporter, but it's no Guatemala for me tonight. On the other hand, WD8VN in Ohio on 17 metres provided a nice cross-Atlantic QSO. No-one else audibly on the band, so I had him to myself. Not easy - some QSB - but always good to work over the puddle.
