Decided to add ISS operations frequencies to my SDS200 connected to a Tram 1410 antenna. Knowing that hits would be few and far between because an antenna with circular polarization is the norm for satellite comms. I gave it a shot and below are the frequencies I added.
121.125 FM RS EVA from Orlan suit [Credit N5VHO]
121.75 FM Downlink from Soyuz-TM (voice). RS EVA from Orlan suit. Soyuz VHF-2. Progress Telemetry. [Credit N5VHO]
130.167 AM VHF-2 Downlink from Zarya (Service Module). RS EVA to Orlan suits [Credit N5VHO]
143.625 FM VHF-1 downlink. Main Russian communications channel. Often active over Moskow. You can hear air to ground conversations in Russian. Sometimes English when US crews talk to their NASA representative in Star City. [Credit IZ6BYY]
I finally got a hit around 0330UTC, 27 Sept 2023, as the ISS was directly over my QTH. For about 3 minutes I received coms in Russian on 121.7FM and 130.167AM. Eventhough my SDS200 would only tune to 130.175 the AM signal was still a very good copy.
After looking up what was happening on the ISS on the today. I believe I found out that what I heard. The crew were making preparations for the undocking and return of the Soyuz capsule that brought home 1 American and 2 Russians.
