[amsat-bb] RS-22 beacon is very strong

[Henk, PA3GUO]

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).

(click on LOG in the top-menu, then on RS-22 in the left-menu)

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