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

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.
