Single-channel FM Satellites in operation:

AO-27 - Mode J, 145.850 mHz up/436.795 (+/- Doppler) down 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,

New to SAT – BB (one week) Could I please ask – how many SATs are currently active carrying transponder for amateur radio voice communication. And the designators as called (such as AO-7, AO-51 etc) and which SATs are linear (SSB / CW) and non linear (FM)

Regards, Stephen ZL1TPH
