Re: AO-27 Telem



Hi,

You can analyze this AO-27 telemetry (KISS frames) and you see the simple
structure 

1 Byte channel number + 1 Byte channel value (starting with Channel nr 07)

ctrl: 6 {I03^}  PID: 2 {UNKNOWN}  Total Frame Bytes: 131
   1 > 07 00 08 AB 09 00 0A 98 0B 98 0C 00 0D 00 0E 00 0F 39 10 04

I found this but I believe it's not all (missing channels 07-15)

AO-27 is similar to IO-26 (or the other microsats AO-16 ... AO-19).

If someone of the AO-27 team could check this?

 Hi Chris,

 I think it's impossible the receiving of TLM without a TNC (hardware).

I tried also with "standalone" 1200Bps AFSK softwares for  packet radio
(like MIXW etc) without success.

 And yes, the TLM is "ON"  just for a few seconds at the beginning
(and at the end) of each "active" pass.
