Dear all,

Encouraged by the RS-15 results earlier today I also wanted to try to receive RS-22. I downloaded the lastest keps and tuned a few KHz above 435.352 MHz. Already a few seconds before AOS I could hear the FM data signal. Signals became very strong - stronger as the AO51 435.3MHz downlink. During the middle of the pass I switched to 145.818 but did not hear anything.

At the time NOVA calculated max elevation, frequency was exactly 435.352MHz (in line with web documentation).

Almost the entire pass an FM data signal was present (documentation says this is typically done while flying in range of Russian command). Only at the end of the pass the beacon switched to CW telemetry, but at a much lower rate as earlier samples I found on the internet. Distance between each packet (packet lengths varied from 5..7 seconds in length) was quite large (13 seconds).

MP3 recordings are available at: http://www.qsl.net/pa3guo (click on LOG in the top-menu, then on RS-22 in the left-menu)

Equipment used: 7 elements beam, no pre-amp, TS2000.
