Hi Julian,
You got me laughing there with your comment about Thursday, but seriously,
it is OK if you can enjoy APRS this way since you drive in the country.
When I also drive in the country I hook my GARMIN GPS and have a moving map
too, or maybe when I have the time I will stick somewhere in the dashboard
the special craddle I bought for my PALM last XMAS, but as you say it is
far too dangerous to do such a thing when driving in the city, so I think I
will stick with my D700 and blind GPS most of the time.
Same goes with my D7 and GARMIN GPS which I use when I take a mountain hike
or mountain cycling (I live nearly half way up Mt. Ymittos in Athens). I
just use the D7 on APRS mode and the GARMIN as a GPS and map display
device. Works FB and I am very happy about this setup and I would'n really
change it for anything else due to it's simplicity. Few things to go wrong
with this setup. Also I never need more accuracy than this system can
give.
It depends on the style of one's life I guess.
Regards

Sorry, I'm a few days late reading this. Why not just use a couple of 2
meter HT's set on a simplex channel other than 146.52 and use full PL on
it. If you use an odd Pl in the two hundred range, chances are other
folks won't get in on it. I would think that would be simpler, and for
the immediate time cheaper than FRS. Just my thoughts. 73. Keith.

All,
Are there any APRS programs other than APRSdos out there that support APRS
TT that Bob has developed?
I also believe that APRS TT did not take off because no one offered any
kits to build decoders/encoders. (At least none that I have ever seen.)
Thanks for any information.

That data was from over 13million packets, over a billion
characters, over several days. Several rush hours got in there, and
perhaps a weekend. The data is quite good.
You should be able to derive the subset of numbers you're looking

In my post, I specifically said add a new port to the existing servers that
would handle an expanded protocol for transporting the packets with a PID
designation included. I don't see a distinct difference in what you are
suggesting.
Adding port on an existing server doesn't imply that the existing software
would do anything with that traffic.
I'm not trying to take credit for you ideas Pete. I am just trying to make it

Be careful of generalizations. Not that it makes a difference in
all this "discussion", but I suspect there may have been a few
Xastir users in that area, considering that the area was so large
and had some major population centers in it. Those stations would
have received/decoded the OpenTrac packets.

A couple of hours. Most that have played with Perl any length of time

Please re-read my posts. I specifically said that the current APRS-IS
servers can NOT support such a port. The APRS-IS server design
requirements specifically preclude adding other protocols to their
architecture due to the requirements of the APRS-IS network design and
operation.
This is a point that you apparently are having a hard time grasping.
Simply put: the proposal for a "universal" interconnect protocol as
presented by me in my previous posts will not have any direct affect on
APRS-IS servers, IGates, or clients.
The "universal" protocol will be available, if the software authors
desire, to interconnect, but the APRS-IS servers, IGates, and clients
will not process or present any other protocols. The servers will not
present non-APRS ports. It would make no logical sense for a piece of
software that is written for a specific network design to be "expanded"
in such a way as to break that network design which is what you proposed
would do. This does not mean that clients cannot process multiple
protocols. It means that the APRS-IS portion of what they present will
be the APRS protocol because of the inherent design specifications of
APRS-IS.
To explain further, APRS-IS servers will NOT be routers/switches for the
new protocol; they will be simply clients. The new protocol will
dictate a completely new network design. As I said previously, this is
no small task and will not happen overnight.
I hope this clarifies things so you understand that your proposal has
nothing to do with what I described in my posts.

Hmmm. I really don't see it as outdated, since it works good for me and
the radio. and other folks communicate with my D-700 and me on a regular
basis. And, with my GPS attached I can view other stations positions and

I too, am just a user. I am a user of Kenwood, a user of APRS, and a user
of amateur Radio in general. I have no pecuniary interest in any. I do
not see where the logic in your assertions lie. I believe that a VAST
majority of the Kenwood users that use APRS with their D-700 or D-7A are in
fact at least nominally satisfied with the performance, or would they not
sinply find another means of doing APRS. Is this not at least a minimally
logical deduction?
One other question. Do you own and/or operate a D-700 or D-7A?

Actually, it's not really incredible. One for the second vehicle (will
probably be in my better half's callsign since she uses it regularly, one
for the house to play standalone digi and also allow me to use the other
side for reg 2M and 440 (I know Bob would probably think it a waste of a
good radio ;-) ), And a D-7A for each licensed amateur in the house
(currently 4) as the local messaging capability to each other will pay for
itself as opposed to one of those fancy messaging phones in a year. No,
not all of them will be on the air at one time for the most part, but I
would say at least 2-4 will be at any given time. :-)

My apologies on this then. I'll go back over it, as this is one thread
I have been following. But yes, I'm not really ready to leave DOSAPRS
as my mobile laptop, which I hook to my d_700 sometime for full screen
capability, is a DOS based computer with only windows 3.1, and let me
tell you, DOSAPRS works great on it. Now I will admit I've upgrade to
the more recent version of the software, but I'd prefer to keep getting
the most out of that old laptop. Want to get my 5.00 out of it that I
bought it for <grin>. Enjoyed the discussion. 73. Keith.

It wouldn't have been your negligence anyway if that PID check stuff hadn't
been enabled: It's obvious that many people on the SIG didn't know about
it at all, and the spec can be read in a way such as to give the impression
that it might not be necessary to do that filtering. Without that
filtering though, any AX.25 packet with a different PID (and not just
OpenTrac) can cause serious problems with APRS clients. Best just to
enable the filtering and go on with life (and I'm sure we all understand
that now!).
I find it very interesting that the non-APRS PID packets didn't affect
anyone, not even the HamHUD. Now we're down to what has been described as
an annoying APRS bug in the HamHUD, which was probably triggered by the
longer APRS-format packets (not OpenTrac, 'cuz it never came out of your
TNC that had PID filtering enabled).
Hopefully Scott and the hard-working HamHUD team can squash that bug that's
been plaguing you guys for some time. I know what it's like to have a few
annoying bugs that take a while to find! Good luck.

I believe he meant Kenwood owners that are not using the APRS features. I
know several Kenwood owners that are in this category. Most of them
intended to get on APRS, but just aren't there yet, so they're using them
strictly for voice rigs.
Doesn't matter though, I've posted real numbers from captured packets. Perl

I'd like to amplify on Steve's comments about the FLASH in the Kenwods:

AND only 10% of users ever upgraded, so that Kenwood never even recouped
their investment. THEY LEARNED THEIR LESSON:
1) Hams are too cheap (as a group)
2) Will BITCH no matter what you do
3) Some Hams insit on perfection or shouda/coulda/woulda
4) All it takes is one constant complainer like Jeff King (who doesnt even
own one, but who lambasts the (1994 product endlessly for not having
user FLASH] (which wasnt mainstream until later)
5) ANd with the internet, one loud complainer can sour the whole pot.
The D7(g) model upgrade was a BIG improvement. It brougth the D7 up to
APRS SPEC compliance (The first D7 was finished in 1998, 2 years before we
even had an APRS SPEC). Yet only 10% ever upgraded. Apparently even those
users are HAPPY!
That is why (in my opinion) you will not see an upgrade until there is a
compelling reason. And just making programming easiler for programmers
(OPENtrack) is not a compelling reason... to ABANDON all existing users,
or to go the expensive upgrade route and have a Public Relations LOSE/LOSE
situation...
Complain all you want. But until you can show a business model of how a
company that can only sell say 5000 APRS radios to a very tiny niche market
where it costs $60 to upgrade and only 10% of them would, dont hold your
breath.
Save your breath. Find ways to USE WHAT WE HAVE in HAM radio to serve our
Ham radio mission and not job-security for programmers... I sure wish
those programmers would use their energy to send to me, in my car, onto the
front panel of my radio (Kenwood) usable real time information (APRS) on
thinkgs like Traffic speed, wrecks and backups. Where the Fire and
Emergency vehicles are, etc...

Drew,
Fantastic work!
It sounds like you are adding greatly to Hams knowledge of the D700. Now
let me toss this out:
1) I assume the D700 DISPLAY head is completely programmable. Thus, it is
only a display and the radio tells it what to do.
2) Reason I say this is because the SAME control head can work for the
TS-2000 and do totally different things and the TS-2000 was developed after
the D700.
And it is just a single serial port between the control head and the radio.
Thus, hacking it should be TRIVIAL. Just tap the serial data line to the
control head (1 of 4 wires) and WATCH what happens.
Turn a knob (look at the response)
Push a button (look at the respons)
Watch a packet (look at the response)
Then having done that enough, build up a table of the protocol and then we
should be able to send anything to the front panel.
Just what HAMS like to do.
So much fun, so little time....
But great work!

Telnetting into my e-mail server and checking my mail with Procomm works
good too.. But I would like something better.
I think the one thing that the powers at be keep missing is this. If we
HATED APRS, we wouldn't be here. APRS is great. My wife gets sick of
everything in my house being APRS this, APRS that.
The issue a LOT of us have is that the system for improving APRS sucks. We
can't update the protocol because, as Bob argues, "The kenwoods would
become obsolete" and "we would obsolete 20,000 users". There are
provisions for custom extensions to the protocol, but there is no working
group to decide what is added and what isn't. Bob just slaps what he sees
fit on his addendum page, and that's all there is to it. What if Bob
doesn't like my addition but others do? Too bad! What if we don't like
Bob's addition? Too bad!
Most of us just want APRS to be the system it CAN be. But right now, we
are stuck in 1999 and forever will be until something dramatic changes
things.
KA> One other question. Do you own and/or operate a D-700 or D-7A?
No. I guess since Jeff got asked this question, I get it too, huh?
I have purchased a few radios since the kenwoods came out and have steered
clear of them. I try to never buy 1.0 of anything, hardware or software.
The kenwoods are a perfect example of a "work in progress" as even the G
models have flaws that remain.
Of course, the biggest flaw of all is that the version of the APRS protocol
in these radios is set in stone. I don't need to go into this again. It's
a fact, and there is no way around it.
