Apparently I never wrote it into the spec, just asuemd everyone agreed it made sense.
So I did add it to the APRS1.2 page in April of this year.
THe original spec was clearly defined as 5 channels of fixed 3 digit values. It became obvious that 000-999 also fit within the fields and so it made no sense to limit values to 000-255
All of my APRS satellites have assumed that 000-999 is perfectly legit in the standard telemetry format.
And other telemetry projects of mine. I think I changed the spec in about 2004, though AE5PL refuses to acknowledge it in his decoders.

Nope. I don't remember that, but Hessu has proposed extending beyond
the 0-255 values and there's also a Mic-E version of telemetry that goes
directly in the position packet comment.
Do you have a reference for Bob's proposal?
