[amsat-bb] Re: Circular polarization

[N0JY]

That has been my assessment and experience, too.  Signals are consistent 
and there isn't any fiddling or switching polarization to worry about 
although I do find different results in signal strength between RHCP and 
LHCP on the same satellite sometimes.
