True. I agree. PHG is not supposed to be interpreted as a line in the
sand where RF from a station just ends. PHG is just a way of reporting
relative station capability. Just sort or providing information that is
available. Interpreting the overlapping signal contours and deciding
what is the most probable emitter of interest remains a human intuition
task based on all of these and other relative data inputs on the
interferring jammer or signal.
For packet you are absolutely correct, that the easiest thing is to just
decode it.
But the reason I mentioned the APRS signal localizing technique is because
so far no one has been close enough to the signal to decode it. ANd the
APRS Omni-Signal-Strength method can solve that part of the initial
problem. it can almost instantly tell where the signal generally is so tht
someone can drive over there and monitor for one good packet and end the
problem.
Thanks for letting me clarify how to use this technique. Also, DFing it is
good practice. THink of this as an opportunity to practice signal
location for those times when it is not as easy as just decoding the
packet...
Just some thoughts...

I tried using the terminal prgms since there is some Telpac/Winlink
activity here (just getting started) and the packets might not have been
aprs. So I was trying to monitor the raw packets....

APRSDos will do that just fine ;-)

Thanks for the suggestion... but unfortunately all those were on as well as
Monitor.. must have been a handheld or low power mobile since I couldn't
hear the signal on the input (and I can hear most city stations direct).
What is really weird, one of my digi's was a culprit about 5 years ago. At
the time I had left the microphone connected to the FT-2600 and someone
decided it would be nice using a 400 foot tower to talk to repeaters...
they left it on a repeater channel and someone did decode my packets at the
time to let me know.
I have since locked the radio and removed the mic!

Hey, this looks like fun!
I'd like to put out a request for one other thing, though -- I recently
acquired a bug -- see it at
http://s3.photobucket.com/albums/y72/elsie1/Ham_Radio/ -- and I wish I had
a simple way to connect it to my computer so I could practice with it. Is
there such a program???
Thanks,
Earl

How about with PASSALL on... can you decode anything on the output?
How accessible is the repeater site? Could you go there with a laptop,
radio & TNC and try decoding the packets there? If you are going to go to
that trouble... how often is it beaconing?

Subject: [aprssig] Miniature digipeater controller?
Has anyone come across a miniature digipeater controller similar in form
factor to things like Scott N1VG's OpenTracker or the like? A KPC3+ is
actually a bit too large for what I want to accomplish.
I'm trying to fit a digipeater into a very small container using just the
controller and an HT. The HT will be one of the thin Alincos (it's
something like 3 x 2 x 0.5 inches). The controller, ideally, would not be
much bigger than the HT itself to make this thing very compact and light.
Thanks,
Alex

How does one eliminate the H2O Gage objects from the maps while connected
to the UI-View inet. Here in Wyoming it's filling up the whole map and
covering the APRS stations.

Scott's Tracker2, which is in beta (I think). Not sure of the final form
factor(s) to be available, but the beta version board is about the same
size as the radio you've got (maybe a bit wider) and can digipeat in a
smart manner, somewhat like the Xdigi.
IIRC, Scott has an OT-sized T2 in the works, but I'm not sure how far out
that is.
Oh yeah, the Xdigi isn't much bigger, but the T2 has a _lot_ more features.
