Re: AO-10 frequency unstable again ??

Yes, the solar panel angle must be increasing if for no other reason than
the frequency shift is gradual and all in one direction--lower in
frequency.  AO10 remains a superb bird especially near apogee as Ib has
noted.  We might ask the Europeans to stay in there just a bit beyond 2200
UTC so that those of us in the Western USA can QSO you!  Cliff K7RR
