Subject: [aprssig] UNPROTO TOCALL for Kamtronics KAM XL
If I was using a KPC-3 for my digipeater I would use APN3xx.
What is recommended for the TOCALL field in UNPROTO and LTP's, when a KAM
XL is the APRS digipeater?
Thanks, Clem -nr3u

How about APNXLx
How many different ROM versions are out there? A single digit x is not
sufficient, but maybe the best we can do. There wont be many, anyway...

There is a service bulletin on this modification on the Kenwood USA web

10 digits plus 26 alphas give you 36 entries. That's not an unreasonable
namespace, even if it doesn't correspond one-to-one with ROM version
numbers.

I wouldn't be able to hear a UT station in IL terrestrially. I'm guessing
there are bunches of these if it's a standard config in a KPC3.
Would actually be interesting to hunt it down. I think I determined it's
north of me because stations that were south of me couldn't digi through
it. I can compell it to transmit because it digipeats on the DISABL call
as well.

You're right... Utah would be some pretty good DX! Thanks to Steve for
suggesting the raw data at www.findu.com/cgi-bin/raw.cgi?call=disabl
You might be able to run down the list and see if you recognize any of the
stations that gated it narrow it down a bit geographically.

That's a good idea to attempt digipeating through it. If you went mobile
with a laptop you could try driving in various directions and observe if the
signal gets stronger or weaker. On the other hand, if you could get others
to try from their home QTHs and either listen or try digipeating through it,
you might be able to narrow it down without going anywhere. Guess that would
be what Bob calls Omni DFing. A directional antenna could also be used to
try and narrow down the direction.
Good luck in tracking it/them down. Hmmm... that could make it interesting
if there was more than one DISABL in your vicinity. It would just make it a
bit trickier to track it down.

Ah - good info! I looked at findu.com, but only for position. Perhaps adding
the time stamp www.findu.com/cgi-bin/raw.cgi?call=disabl&time=1 might help
Pat KA9SCF look at what he is hearing and compare the times shown for the
raw data, but the IGates should be a pretty good hint too. Pat appears to be
just west of Chicago. Looking at nearby activity,
www.findu.com/cgi-bin/near.cgi?call=KA9SCF and the list of DISABL stations,
I didn't spot any callsigns associated with gating the DISABL but I was
going back and forth between two lists that both contained callsigns that I
wasn't familiar with, but Pat would probably look harder than I did!

Subject: [aprssig] Documenting Interface - Trimble Placer 450 GPS
Greetings List:
This maybe off topic a little.......... but I built an interface (using the
Digital I/O port of the Trimble Placer 450 GPS) that shows GPS status, power
etc. I have had several folks that want the info on how to build it so I
would like to document the parts etc. It's not hard to build since it just
uses a project box, 5 LED's and some limiting resistors but I guess I need a
schematic and layout for someone else to copy.
My question is.... what are folks using to show the design of a circuit....
not a PCB, but parts layout etc? Technical docs is not my forte yet....
[GRIN] I do have MS Visio. To see a picture of what I am talking about you
can see the pic at www.ferrell.cc/motorola pretty raw since it was done
just for my troubleshooting........

Note that disable never sends a position, so things like near.cgi have
nothing to work with. As has been pointed out, these are often telpac
nodes. The damage here is also quite minimal, a short packet every 20
minutes.
If you really want to track down the most likely culprit, look for a telpac
node within range of the IGate.
http://www.findu.com/cgi-bin/telpac.cgi?n &call=k4hg
If you make contact, please do so VERY nicely, as they are not causing any
significant damage or breaking any rules. (At least in the US, they send
with their callsign at appropriate intervals, the callsign is required once
every 10 minutes, NOT in every packet).
