Re: AO-51 PBBS OPEN !



Hi Gould,

Thanks for your response. I saw your callsign on both passes.

I will try again when the pass is higher. Seems that 45 degrees is not 
enough from here. Using M2 Yagis with Preamps and polarity switching and 
downlink seems low. Doppler corrected by SatPC32 and antennas rotated by 
G-5500 and GS-232B.

73, Jeff
K7WIN
