EN ÇOK KULLANILAN UYDULAR - TA7OM - 29-12-2008 02:32 PM En Çok Kullanılan FM Ve SSB Amatör Uyduların son durumları: Operations: FM Operation Tips 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 Hear Contact 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 Hear ISS Astronaut making contact with school on 16 Nov 2005 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 |
