SSB Operation Tips

AO-51 [FM] and VO-52 [SSB] are generally the easiest and most reliable satellites to work.

AO-51: FM
Downlink power: Normal-400mW | High-1300mW [per AO-51 control operator group]
Uplink power: 5W ERP is plenty, but QRM sometimes requires full power to overcome
Strong downlink signal
Hang time: Keyed continuously during pass
Uplink: 145.920MHz FM
Downlink: 435.300MHz FM
Digital Uplink: 145.860MHz 9600 baud
Digital Downlink: 435.150MHz 9600 baud
BBS Call: PECHO-12
B'cast Call: PECHO-11

VO-52: SSB/CW
Downlink power: 1000mW maximum--shared across passband--Moderately strong downlink
Uplink power: Suggest 20W ERP (at W8SH, set TS-2000 to Power: 10)
Uplink passband: 435.220 to 435.280 MHz LSB
Downlink passband: 145.870 to 145.930 USB
Beacons: 145.860 (Telemetry) | 145.936 (Unmodulated)

SO-50: requires 74.4Hz PL for 2 seconds.
This starts 10 minute fixed timer--must be reset every 10 minutes.
Then, switch to 67.0Hz PL on uplink to open squelch.
Downlink power: 250mW--but spinning of satellite leads to fades and changes in circularity.
Uplink power: 5W ERP is plenty, but intentional QRM sometimes requires full power to overcome
Hang time: 1/2 second
Uplink: 145.850MHz
Downlink: 436.795MHz

AO-7: SSB/CW
Downlink power: Unstable and varying--FMing due to poor to no regulation of DC bus
UHF/VHF mode:
Uplink power: Suggest 40W ERP (at W8SH, set TS-2000 to Power: 20)
Uplink-432.125 to 432.175 LSB | Downlink-145.975 to 145.925 USB
Beacon: 145.9775MHz
VHF/HF mode:
Uplink-145.850 to 145.950 USB | Downlink-29.400 to 29.500 USB
Beacon: 29.502MHz
Note: The beacons are often several kHz off frequency (presumably, along with the passband)

ARISS: no PL required
Downlink power: 10W--Strong downlink
Uplink power: 5W ERP is plenty, but high usage sometimes requires full power to overcome
Packet bursts are heard about every 15 seconds when packet mode is active.
Packet Uplink: 145.990MHz
Voice/crossband repeat/Packet Downlink: 145.800MHz
Voice Uplink (for rare occasions when astronauts are on voice): 144.490MHz
Crossband Repeater Uplink (rarely active): 437.800MHz
Digipeater callsign (for "UNPROTO CQ VIA..."): ARISS
BBS Callsign: RS0ISS-11

ARISS Packet Parameters:
1200 baud AX.25 | UNPROTO CQ VIA ARISS | Auto LF OFF | Packet Length: 72 | MCOM ON | MCON ON
Kenwood TS-2000 UNDOCUMENTED COMMANDS: PASSALL ON | SOFTDCD ON
