Most of my long haul contacts on AO-7, FO-20 and 29, and now HO-68, are right after AOS or just before LOS, certainly not at TCA. Use my recent QSOs on HO-68 with Argentina as an example. Even when I work Europe on AO-7 it is at the beginning or end of a pass...not the middle.
Bob, SatPC32 will show you the frequency with Doppler shift, and the Doppler shift. A little subtraction or addition and you have what you want. 73, Drew KO4MA _______________________________________________ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
