[amsat-bb] EnduroSat One and EQUiSat identified

Hey there, Milen!

Yeah, if they haven't changed anything, the HS_Soundmodem from UZ7HO will 
decode it when set to 9600 ("FSK G3RUH 9600bd").

You should end up with something like this:

Hi all,

Could anyone advise on what software I should use to decode the telemetry
from EnduroSat? I should have an overhead pass tonight and would like to
give it a try.
The website lists this:

> Modulation: 2GFSK(GMSK), Frequency deviation 2400 Hz, Speed 9600 bit/sec
> Preamble: 5 x 0x55, 0x55, 0x55, 0x55, 0x55
> Sync word: 0x7E
> Packet format: AX.25 UI-bitstuffed, NRZI-encoded, G3RUH-scrambled,
> CRC16-CCIT


Would something like UISS with the High Speed SoundModem by UZ7HO work or
is special software required?

Best wishes,
Milen KG2C
