So, I had pretty marginal copy in both SSB and CW, neither of which were quite good enough to hold a QSO. The odd thing is that CW did NOT improve things, even with the narrow filter on my FT-736R.
The antenna is a 2x16 CP thing I picked up at a swap meet (so I don't know the brand). My copy was better with the CP relay UN-energized, so either it's wired backwards, or something is broken. On the man-made satellites, I have used both polarization settings, so I know they both work. Puzzle. There's also a no-name preamp up there, after a bit of coax to get around the rotor. Below the preamp is mostly hardline. Turning on the preamp results in a small but noticeable rise in the base noise floor, so I believe it is working. And I Just got down from the roof, after checking the aiming using the sun. No problem there. I even played with my W9GR DSP box, trying to pull out the signal. Didn't help much. Don't get me wrong - it was a thrill just to hear the moon. But what's wrong with my setup? The only other thing I can think of was that the moon was north-east of me at the time, and that means aiming through a bit of oak tree. Is that the problem?
