Re: AO-51 PBBS OPEN !



Thanks Drew,
I apprecaite your response.

I could only copy a few lines of the directory at 45 degrees.No trees 
impeding the signal at that elevation or azimuth. Using 30 foot of LMR600 on 
the downlink UHF Yagi with SSB preamp. Using  30 foot of Andrews 1/2 Heliax 
on the L band 22 element M2 Uplink Yagi.

GO-32 passes above 20-30 degrees pegs my s-meter.

I will try again on future passes. I see an 82 degree pass coming up tonight 
and will give that one a try.

73, Jeff - K7WIN
