Already did -- the missing messages aren't anywhere that I can access.
Maybe Yahoo lost them or something. Again...

I donno, I'd probably not want to see these clutter up my radio's list and
my map. These are the kinds of things that should be in the local APRSdata
base so that they will show up from a Query. (Assuming someone is running
the APRSdata engine in the area, or the comparable APRSkiosk program.
Three Reminders:
1) There is only one Btext available in each digipeater. The best use of
this in every digi, is the locally recommended voice-repeater-object, which
is of great value to a traveler entering the area.
2) These local Btext objects are sent DIRECT so they cover only the area
of immediate interest that can hit the voice repeater, and since they are
originated by the DIGI, they add zero congestion load to the channel.
3) Conversly we generally do *not* want to see permanent local voice
repeater objects originated by home stations and other clients. These are
usually transmitted more than one hop (QRM), go outside the area where they
have any value (SPAM), and are originated at the home station where they
cannot hear what the digi hears, and so they add a load to the congested
channel (QRM).
We have a voice repeater object in our area 443.XX MHz, that is being sent
out by a local client via WIDE2-2 (which is almost 100 miles from where the
repeater is.. This packet covers 5 states and about 40,000 square miles of
the highest density APRS network in the world. Yet, a mobile can only work
it if it is within 20 miles of it.
And it is colocated with a digi at the same site. It would be better for
everyone and the network if only that digi transmitted that object as a
BText and only DIRECT to the same RF coverage area where it can be used.
Not the 5 states surrounding it.

Subject: Re: [aprssig] Lasting Compatibility of the D700a
Some of the Garmin updates (maybe half of what I've seen) are *bug fixes*
as well as bells and whistles. The Kenwood doesn't deal with compressed
objects, correct? It sure would have been nice to be able to update one to
comply with the published spec...
You talk about maintaining on-air-compatibility - that's something the
Kenwood lacks in some areas BECAUSE of it's lack of updates. On top of
that, we're now left with a spec that is catering to a device that can't be
updated. We're left with a system that will never evolve with the times.
