This above analysis is wrong becauce of according to the old CW format,
so please analyze rightly again by using the following new CW format.

Dear Mineo,

I'am a little it confused about this telemetry.

HIT2 the first char is month (ok, you assume the 9 is for September ->
what's with October, Novemer an December ?)

The next twice chars are DD HH MM SS but the last two characters?

HIT3 the values are hex values in [C] ?

HIT4 the battery values are VVVV and WWWW, but divided by 10000 ?

There are some open questions to the telemetry values. Could you help
me, please?

Best regards,
Mike
