So your saying that the APRS-WG charter is not the proper mechnism?
Why don't you just cut through all the shucking and jiving here Bob, and
declare yourself the absolute dictator of APRS. I really don't think there is
anything wrong with this, it really brings some clarity to something that

Last-fix handling needs some work. In fact, it got a lot of work last
weekend, but it needs more. For one, I need to find RAM for a fix age
counter. And I really need to come up with a formal state chart that
defines the fix / transmit behavior - it's critical to reliable operation
and it's getting a bit complicated.
I did a quick attempt at a powersave mode last night, too. Seems to work -
I think it drops the average power consumption by 30 - 40%. That's in
'wait' mode - I'm having trouble with the 'stop' mode. If I can get that to
work right, it ought to reduce power consumption even more. All this comes
at the expense of timing accuracy and a slowdown in response time.

You mean like the APRS Charter & spec? If you care to read it, you'll see a

OpenTrak still uses CSMA. Basic layer one stuff Bob just like APRS. TAB put out
a really good book on packet radio, I think it was called "Packet Radio" that
explains some the basic stuff in packet, much better then current books.

The OpenTrac'rs are demanding that the perpetrators be praised and the
victims be punished.
They are using a protocol that is not fully defined, and obviously never
tested in the real world until now. Unfortunately the test platform and
path they used caused us to be bombarded. So bear with them while they
re-invent the wheel. Hopefully, they will do this on another frequency to
minimize the harm to others, but don't count on it.

More OPENTRACK propaganda. Open track doesnt do any of those:
1) It is not readable by Kenwoods
2) It doesnt clutter, because they cannot even see it!
3) Opentrack introduces an entire protocol! what do you mean it
doesnt introduce new parsing rules!

Yes, Ill answer your challenge, but you post your OPENTRACKpacket first. Im

what kind of gobbldygook is this. In the first paragraph you make all

it wont work unless Kenwood recalls all their radios and changes them to
match your new and better protocol.

I never intended to imply anything otherwise. You are a fantastic
programmer and asset for the community, I only said you were new to APRS.
I just wish you were using your excellent tallents to make positive
contributions to the APRS that is, rather than trying to obsolete
everything so that it looks clean on paper..
There is so much you could do that would benefit everyone, instead of
trying to wreck the train so that you can re-build a network of your own

WOW.... catching up on some of the posts, and talk about DejaVu! Those are
EXACTLY some of the complaints when our group first started running TCP/IP
on the amateur bands back in the mid to late 80's, using Phil Karn's "NET"
and then later NOS and all its varients.
Somehow, we got by all that, and the hobby was much better because of it.
This exercise (NET/NOS) even spawned quite a few commercial spin-off's,
such as Tetherless access, numerous PPP stacks, and other things that hams
gave back to the world.
What heady days!!
All I can say, to Scott, Robert, you and all the other experimenters, is
keep at it! This is what this hobby is all about, experimenting and
advancing the state of the art.

APRS is a distributed network, with everyone on the channel sharing
tactical-real-time data of value to everyone on the net. It is not a
me-first-screw-everyone- else channel....
>What difference does it make to anyone whether that
>packet is APRS or OpenTRAC?
Because it is just not gentlemanly behavior on established networks to just
jump in and start transmitting data that is not for the general benefit of
the net or within the stated purpose of the net, or which is encoded such
as to deny others on the net to see it.
>Other than the fact that the OpenTRAC packet is only

That is pure OPENTRAK propaganda. Please show me your packet that contains
LAT/LONG/CSE/SPD/ICON and does it in less than the 25 byte APRS packet

None of those have anything to do with running incompatible OPENtrack

No, but I would NOT WELCOME an SSB station on a designated National AM

No it was not. There is nothing in the APRS protocol that permits non APRS
PID packets on the national APRS channel. Inventing your own non-APRS-FLAG
and then complaining that people dont recognize it as a non-APRS-FLAG is
not fair to your fellow hams.
>2. An APRS packet needs a lot more than a single

When you start throwing binary data onto a channel that has a clear
protocol, then almost any possible occurrence of valid bits can occur. It
is for this reason that we receommended that you not use Binary and that
you not transmit incompatible protocols on the National APRS channel.
>So tell me again why Mic-E was considered a good

There aren't any incompatibilities. Sure people can screw up just about
anything. But there are no TNC's that don't pass Mic-E packets just fine
when properly configured to pass standard ASCII.

Yes, all of which are incompatible with the very fundamnental basis of
APRS. Hence our suggestions to not try to shoehorn it on to the existing
APRS structure but to begin a parallel network which can then efficiently
support your ideas instead of being encumbered by all the problems you
claim the APRS network has.
>Stuff that'd be hard to do in APRS, and that you've

>within the context of APRS.
I wouldnt say "vehemently opposed", but simply "vehemently explained" why
it is a bad idea or won't work:
1) store-and-forward: Not applicable on APRS which is a real-time system
for tactical real-time local events.
2) backbone routing: No one ever opposed this. APRS can do this just fine.
In fact, we have propsed many methods that will work. In fact, Steve's
APRS-IS does that very well right now...
3) digipeater-maintained objects: Crazy idea. OBJECTS in APRS are
supposed to be live, vibrant, moving things like everything that is moving
at an event but doesnt have a tracker. If they are so static that you can
upload them to a digipeater so that it can keep repeating the same
non-moving objects, then they probably shouldnt be APRS objects but should
be map features that should be applied with local map overlays.
It is poor design to take up air time repeating the same non moving,
non-changing objects over and over again on the air? Put them on the map.
Or let the person with the latest info post it. The last thing we need
are digipeaters spewing out more non-real-time packets.
Not vehement opposition, just common sense in good network design...

Bravo and Mega-dittos, Bill.
All RF networks are local. If forced to, we can eliminate the intruders as
needed. We can prevent their access to the infrastructure. No digipeating,
no network.
Others (who manage and maintain) can and will decide for themselves.
At worst this is an attempted hijacking, at best it is a parasitic
infection. It contributes nothing to the aprs network, it merely steals the
resources of the infrastructure, for its own self-serving ends. Go
experiment somewhere else. Some (perhaps most) of us who built and now
maintain these networks are not interested in being "used" as a test bed by
a non-APRS compliant protocol. It's just that simple.
Get over it.

(On its own network, I would consider OpenTrack a an interesting and even
worthy innovation.)

I have no intention of doing anything with any Kenwoods. I'm making a point

not going to ask them to recall all those radios either, are you?

You can do it yourself easily. Just do a scan of the APRS-IS and capture
every digipeater that is running UIDIG code. That will give you a list of

Or scan for all kenwoods, That should give you about 3 thousand on any

And since you can do just about anything within the APRS protocol, I dont
see why you need to invent your own and insisit on obsoleting everyone on
the air...

Yes, too bad you can't seem to understand it.
READ THE SPEC and read my lips:

Nothing selective about it: And I say again:
>>The specs say nothing about how a PID is supposed to
>>be monitored in a TNC.
>>The specs say nothing about how a PID is supposed to
>>be monitored in a TNC.
>>The specs say nothing about how a PID is supposed to

None as I was not running a client at the time, maybe my D700, but
I was not mobile.
I have constrained my discussion to subjects relative to impact on
existing infra-structure hardware, I do not intend to get into a
dissertation regarding coulda woulda mighta dida relative to what happened.
I am not critiquing the Balloon flight I am critiquing the entire concept
of the non-APRS overlay..The balloon flight merely brought it all to the
top of the list..

Sorry, thats about as logical as saying that because all CARS are required
to have wheels, that since your JET FIGHTER doesnt use wheels, that it can
do anything it wants on the public highways...
What arrogance!
