Hi Bob, I use the Sun, late in the afternoon. The satellite program tells me where the Sun should be, and I aim the rotor to match. Then up on the roof I go, to align the rotor mount so the shadow runs down the beam. Worked quite well for aiming at AO-40. Of course in the Pacific Cloudy West, you may have to wait awhile for a clear day... Greg KO6TH

You'd think I would have this figured out by now. I never paid very close attention to exact antenna direction until now. I mean the satellite was always within the beam pattern. I tried the SuM part of Satpc32. I am thinking of trying some EME, and I looked up the boom of the yagi' and I was about 8* high and maybe 10* to the right of the moon, still probably within the half power point of the beams. This is where the obsessive part comes along, should I use the moon as the "grand phooba" of calibration? Or compass true/mag. I mean the moon is "pretty" consistent. As always the collective thoughts of this bb are never wrong. 73 Bob W7LRD Seattle _______________________________________________ Sent via AMSAT-BB@amsat.org.
