Great pictures. I think I can answer all of these, more or less as memory permits.
1. Yes – This was one of my best ever FDs!
3. John Petrich’s vacation home on Whidbey Is.
4. Wire Yagi antennas on 20, 40, 80m in trees high above house. Great take off over salt water to the east.
5. Line shot over tree limbs with bow and arrow.
I’ll always remember grinding out QSOs with east coast stations on 80 meters CW in the middle of the night. We had multiple stations calling us that we had to dig out of the noise, but they were hearing us. That Yagi really worked well!
