Detailed doppler measurements show that EnduroSat One (downlink 437.050 MHz) is object 43551 (1998-067NZ) and EQUiSat (downlink 435.550 MHz) is object 43552 (1998-067PA).
No signals received from MemSat (downlink 437.350 MHz) and RadSat-g (downlink 437.425 MHz).

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

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:
