All,
on 435.315 MHz (FM) you can hear RS-30 APT transmission.
It looks like test pattern. See here: http://www.dk3wn.info/images/rs30_apt_test.jpg
I used WXSat for decoding. Here is the section from wxsat.ini for decoding:

Thank you very much, David (GM8ARV) for pointing me in the right direction :-)

There was some conversation about this transmission on the HearSat mailing list...
Its not clear if this is a test pattern, or what, but it probably won't come down like a normal APT image (e.g. Visible and near-IR bands).
