[amsat-bb] Question from Newbie

[uli at df5sf-qrp.de]

Hello Don,

many thanks for your infos.
If I understand aright I have to change the TX frequency for AO-85, AO-91, AO-92 because of Doppler shift.
See https://www.amsat.org/wordpress/wp-content/uploads/2018/04/FoxOperatingGuide_2018_Lo.pdf
Opposite is SO-50. There I have to change the RX-frequency.
See http://www.amsat.org/wordpress/wp-content/uploads/2014/01/Work_FM_Sats-20131010.pdf

Antenna is ready. Now I wait for a good satellite pass.

Just ran across this handy guide from K6LCS's site, www.work-stat.com:
 http://www.work-sat.com/Home_files/FM-VOICE-SATS-1Q-2018b.pdf  Sadly
AO-85 is not on the sheet, but it should not be hard to figure out what to use following the same for the other Fox birds (AO-##'s).
