[aprssig] APRS Telemetry Parameters

[Dave B]

Can't get near that APRS101.pdf doc, all our AV/antimalware screams at 
me, and blocks downloads of PDF's from that site!   Odd...  (Unless 
something has got in to that file?)

But get the overall drift of what is needed it from your summary.
"value = A x v^2 + B x v + C" where 'v' is the value sent in the 
telemetry packet.

Perhaps that info could go in the document too, to be complete, with 
perhaps a reference link to the APRS101 document.

Regards.
