You have interpreted the AMSAT rules correctly. However, we are not in a
position to interpret the ARRL rules. I would suggest contacting someone
at the ARRL for clarification. Even asking another ham could lead to
that ham's interpretation and not the real deal.

Just listened to RS30 for the first time on 435.315 ish
There's an interesting data mode that follows the short periods of CW
telemetry. It appears to comprise of data being transmitted at 4800 bps in
some
form of 'packet' at around 4 times a second.
I'm not good with data modes but that's an assumption based on a
transmission which has a carrier in the center with peaks of energy at plus
and minus
2400 Hz but with the whole 4800 bandwidth occupied. Does that sound right?
(Recorded using spectran)
As the signal is transmitted you can count another 'rate' which works out at
250mS.
Too wide for my radio on SSB. If it's a picture, I wonder how it's
decoded?
There's an overhead pass in Europe with AOS at 17.09 and LOS at 17.32.
Will try FM next time.

Gary,
As I recall AO-7 and VO-52 are not FM satellites, hence exempt from the rule
so is FO-29

I found CW 435.315 and 435.215 MHz accidentally by chance.
I confirmed today that Yubileiny were transmitting both of
435.315 and 435.215. I decoded 'RS30' letter both of them,
using object C, 17:39:00-18:00:00UTC, 25May2008.

Yubileiny switched on when about 10 degrees elevation from northern Russia,
with intermittent FM bursts of a few hundred ms.
Then a few second bleeeps reminiscent of WEFAX synch bleeps followed by
continuous FM packet; could not decode the packet in WEFAX decoder however.
Will try again with mixW.
CW sent after the FM, seemingly on command:
eauset 4
ix 544
avu 54
usun 1
isun 0
itxa 6
(fm key) *3
rs 30
us 164
ibs 76
(fm key)
rs 30
(fm key)
rs 30
us 162
ibs 12
(long fm data - gone).
These are mostly the same as in RS22 (I've taken the decode from contributors
to Mineo's web site).
US seems to have replaced UBS in RS22 : On Board voltage /10
IBS On Board current /100
USUN Charge Voltage from solar battery/10
ISUN Charge current from solar battery /100 Amps
ITXA DC Current of the Tx (it was 145 MHz tx in RS22) /100 A
RS22 telemetry did not refer to:
eauset
ix
avu
however I recorded these from FM keying not cw so they could be incorrect.
Therefore the values we definitely have are:
On Board voltage /10 = 16.4 or 16.2 volts (my value yesterday was 16.3)
On Board current /100 = .76 or .12 A (the letter seems low)
Charge Voltage from solar battery/10 = 0.1 Volts (seems low)
Charge current from solar battery /100 Amps = 0
DC Current of the Tx (it was the 145 MHz tx in RS22) /100 A = .006
This suggests she's not charging.
