The payload will provide resources for radio amateurs worldwide to make contacts with onboard astronauts or to communicate with each other. The first phase of the payload is capable of providing the following functions utilizing the VHF/UHF amateur radio band: 1. V/V or U/U crew voice; 2. V/U or U/V FM repeater; 3. V/V or U/U 1k2 AFSK digipeater; 4. V/V or U/U SSTV or digital image. The following frequencies have been coordinated: - V/V crew voice NFM 145.850, 145.985 - U/U crew voice NFM 435.050, 436.510 - V/U FM repeater NFM 145.875, 436.510 - U/V FM repeater NFM 435.075, 145.985 - V/V digipeater AFSK-FM 1200 145.825, 145.825 - U/U digipeater AFSK-FM 1200 437.550, 437.550 - V/V imaging SSTV-FM 145.850, 145.985 - U/U imaging SSTV-FM 435.050, 436.510 A launch to the Chinese Space Station is planned for the third quarter of 2022 from Wenchang.

Telemetry antenna suggestion
by z man 05 May '22

05 May '22

Hi all, I am in search of an antenna that I could use to receive the 2 meter telemetry signals from AO-73, Nayif-1, etc. While I am having good success with my Yagi setup, I would like to eliminate any computer control of the antennas. My question is what would be a suggested antenna I could possibly build? I'm testing out a Lindenblad in RHCP, but so far (2 days in the air) I'm not seeing any decodes. Would receiving the 460mW beacon from EO-88 require a steerable antenna? Thanks for your help. Larry N1MIW
