AO-51 - Mode J, Active frequencies change. Check the AMSAT-NA Web site for current configuration.
SO-50 - Mode J, 145.850 mHz up/436.795 (+/- Doppler) down with a PL tone of 67.0 Hz.
International Space Station (when active) - Mode B, 437.800 mHz up/145.800 mHz down.

CW/SSB Satellites in operation

AO-7 - Mode B mid-passband is 432.150 mHz up/145.950 mHz down.
FO-29 - Mode J mid passband is 145.950 mHz up/435.850 mHz down.
VO-52 - Mode B mid passband is 435.250 mHz up/145.900 mHz down.

Doppler, of course, also will affect the CW/SSB satellites.

Welcome to the satellites! Very best 73s,
