I have just put up a wide digi in Quincy Illinois. We are not sure if
it is doing its thing.
Here is some input that I am seeing when I do a query.
20030805053337,W9MDO-1>APS221,RELAY,WIDE*,qAo,AB9KF:>041229z[221]Quincy,IL
The W9MDO-1 station is in quincy. I am AB9KF .. does the RELAY,WIDE* mean
that W9MDO-1 came to me via a wide digi and then I put it on the internet??

via a relay, then a wide, and then through your IGate.

That's already happened, to some extent, in evaluations of critical
infrastructure mapping. Don't get me started about what's "critical
infrastructure" in Texas, and I'm on that committee...
The majority of exclusions are voluntary with some limited guidelines.
Most have already been implemented. I do not expect to see any more
major deletions.

I've been running a 100% Solar Powered WX station and Digi for several
years. It's now morphed into a full fledged solar powered 2M repeater
co-located w/a WX Digi.
It originally started out w/an HTX-202,Diamond X-200, KPC-3, 17 aHr gell
cell, and a 32 watt Solarex Panel. The electronic equipment was installed
in a wood box that was the size of a large birdhouse (but WX proof). The
box was installed on a 1.5" black Iron pipe high enough to be out of reach
of vandals. This worked well for years, despite having to reset the TNC
every once and a while because it was sending the same WX report
everytime.
If the site you have is WX output only (not a digi), then power save
feature will only help you conserve battery. My site is atop a hill, and
works as a digi, so the powersave feature will ignor many packets incoming
to the site.
See W1WQM.org and look under photos for what it has become today, an 8x12
shed w/a 75' tower!

I'm wondering .. would FINDU track an OBJECT of "146_895" (info on local
repeater)?
I'm not seeing it in Findu, but that's not a surprise: It has no digipeater
in it's PATH, so it might not be making it to an Igate .. or maybe
FINDU or the IGate software filters it out since a.) its an object or b.)
its probably not a unique name (as a call sign is; there might be several
such objects in the US with that name; how would you differentiate them?).
Anyone know the answer? Just curious ...

Hey Rod,
These are the settings I used on my Pico-Packet as a
tracker:
MYcall N8DEU-12
UN APRS VIA RELAY,WIDE2-2
LPATH APRS VIA RELAY,WIDE2-2
LOC E 6
MYP N8DEU
CTEXT >Send reports to N8DEU@N8DEU.#HSV.AL.USA.NOAM or n8deu@amsat.org
CMSG ON
CMSGD ON
BTEXT >Send reports to N8DEU@N8DEU.#HSV.AL.USA.NOAM or n8deu@amsat.org
B E 60
TXD 30
This sets the Pico to transmit every 60 seconds when I am on the road. I
use the CMSGD setting to prevent folks from connecting to my Pico and
disrupting my tracker beacon and they get the CTEXT message as they are
immediately disconnected. Somebody once connected to my tracker and it
would not beacon until they disconnected which never happened. That is why
I added the CMSGD parameter setting to my tracker.

Yes, it does, I just tested using xastir to create an object in S. Florida
with that name. To see if any of your packets got to the internet system,
you could use the raw cgi with the callsign of the sending station:
http://findu.com/cgi-bin/raw.cgi?call=k4hg-1
>I'm not seeing it in Findu, but that's not a surprise: It has no digipeater
>in it's PATH, so it might not be making it to an Igate .. or maybe

You wouldn't. The design of APRS is such that no one owns an object. Anyone
choosing to can "take over" any object, and move it. This is by design, and
is considered an important feature. If the object you are sending ever
makes it to findU, it will move the object I created.
If you want to use an object on findU, you need to make sure it has a
unique name. Before I placed the object, no one had used that name in the
last 10 days, there a couple other frequency objects starting with 146, use
this URL to see:
http://findu.com/cgi-bin/find.cgi?146*
You cannot stop someone from moving that object, but if someone were to
want to place that frequency on the map, and cared about using findU,
hopefully they would check forst to be sure that object name is not already
in use. If they don't, and start sending object reports, the position of
146_895 will ping-pong between the two positions depending on which got to
findU most recently. If you want something no one will accidentally reuse,
you should use something starting with your callsign.

This is a good point. A possible solution: use the repeater's callsign
with a -R suffix (if multiple, -R1, -R2, etc.). Then, in the text of
the packet, put the frequency, tone (if any), and offset. Same
principle could be used for the various Internet link systems but maybe
using I instead of R. Then, you have unique names which are readily
identifiable as repeaters.
For instance, our local club repeater object would be:
AE5PL>APRS:)W5MRC-R!lat/lon/symbol 146.74- no tone
Note, I am using an Item here as the repeater is not time sensitive. An
Object could be used as well.
Just a thought.
