Bob,

Be wary of AO7!  It is my old standby, and I do a 
lot of listening...In attempt to determine a 
pattern, but my efforts have been fruitless..

Today, 1feb08z, I chased the band and NOTHING 
until about 30°, then the sigs were erratic...made two contacts...

Sometimes it is loud and clear AOS to LOS...

Not suggesting that is YOUR problem, but be wary, 
my friend....And I have nothing but sky from 
horizon to horizon...with my sat antennas....

                    Disagree: I learn....

               Pulling for P3E...
