[amsat-bb] YUBILEINY: Some CW decode, some FM packet

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:
(fm key) *3
(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:
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.
