The New-N paradigm is a layer 2 convention for source routing of AX.25
traffic; it is an issue completely unrelated to the format of an APRS
packet in an AX.25 payload.

Bob, this is your personal web site, and the contents have not been
formally adopted by the community, or even seriously vetted for
technical inconsistencies and backwards compatibility issues such as
the one we are discussing.

Sorry, the only quirk I see is with a new piece of Kenwood hardware.
How much trouble would it be to apply the same terminology to Tnnn
(i.e. "anywhere in the comment") so that it does not break the
original formally adopted spec as well as the vast majority of
stations using altitude in a way that meets that spec?  The D710 has
field upgradable firmware so a change could be pushed out to this
device that represents a tiny handful of devices on the APRS network,
instead of declaring a large number of stations on the network broken
because the D710 can't handle it.

Maybe the reason we don't see more APRS radios is because the vendors
don't want to deal with trying to meet such ill defined and amorphous
"standards"?
