Subject: [aprssig] RE:Solar Powered Digi
I used an HTX-202, KPC-3, and a Peet Bros. WX station all solar powered for
years until I upgraded, by building an 8'x12' shed to house the voice
repeater and associated gear... all of which is still 100% solar powered.
HT's use less the least amount of power when idle (30-50mA) compared to a
genuine mobile rig (+500mA). I installed all equipment in a box the size of
a large birdhouse mounted to a piece of black iron pipe imbedded into the
ground. Atop the pipe was a Diamond X-200 antenna, at 10' above ground
level was the enclosure and the solar panel was mounted overhead at a 55
degree angle. The battery was a 17A/hr gel cell and was charged w/a 30 watt
flexible panel rigidly mounted over the enclosure to keep rain/sun off the
enclosure. A small solar charge controller was also squeezed into this box.
For just a few days, a simple HT, TNC, known good charged battery and
simple verticle antenna should do just fine. If you want to keep out all
the unwanted packets, use a different frequency than the APRS standard.
That way you won't QRM the network, and they won't QRM your event. I do the
same thing for Tour de Cure (American Diabetes bike tour in SE New
Hampshire). I issue Open trackers to participating vehicles on a discrete
frequency, crank up their TX rate so net control has updates every minute
on their positions throughout the event while they are in motion. I also
change the frequency of the two local digipeaters to match them for the
weekend. Works great, and gives net control much better SA when things go
bad.
Good Luck!

What I have are Yaesu Ft-2600 mobiles and KPC-3's so I'm kinda stuck with
that. Have some fiberglass 30ft poles (like they sell on E=Bay) and Diamond
X50 antennas. I like the idea of the box for all the electronics. I have
the batteries but not the solar panel or controller... got to look and see
what is available on the cheap. Problem will be the setup and takedown since
the route is 100 miles on the Sat then 100 miles back on another route
(pretty close to the first one) on Sunday. We did it last year with a couple
of RV's serving as the temp digi's but we are minus one this year and we
could have had better placement of the temps as we analyzed the route after
the tour. Here is the URL of the tour: http://cccyclists.org/tosrv.php

Sounds like alot of work changing freqs. Seems to be easier to change the
digi's to only respond only to the tactical path (remote in to change) so
they won't hit any other digi's out of the area. Not too much a problem here
in FL/So Georgia with the traffic that we have unless the band opens.

Subject: [aprssig] Stupid D7 tricks
I was experimenting with GPS pass through in packet mode on my D7 and D700
and had a little bit of fun with this command:
GPSTEXT $
Yes, it's just a dollar sign and nothing else. Watching the stream with
LTMONITOR set to 1 second, more than one NEMA sentence was making it
through the pass through.
Like I said, stupid D7 tricks but I thought I'd share just for the fun of
it.

Thanks to everyone who has replied to my enquiry re routing.
Given that my DigiNed digi (vk2tv-10) will become almost transparent when
the remote digi is installed, I believe that WIDE1-1 is an appropriate
alias.
As for the remote system for which I suggested WIDE2-2, I'm still not sure.
I seem to be missing something with regard to WIDEn-N routing and have been
doing lots of reasearch to defuddle my brain. I understand how the SSID is
decremented after each hop, but what yardstick is used to determine the
initial numbers used for n and N?
Keith VE7GDH asked about the trend in VK re routing. The answer is I don't
know. I enquired through some local APRS web pages but didn't get replies.
But that's a bit irrelevent anyway because I'm more interested in doing it
right, rather than doing it just because others do it a certain way.
Given that the first remote digi is still to be installed, much of this is
hypothetical. If I start with WIDE2-2 and no other systems are installed,
there will never be a problem. Even if a second system is installed,
WIDE2-2 still can't propagate beyond that second system. By the time a
third system is installed I'll be using a walking frame to carry out
maintenance :-)

Subject: [aprssig] Re: Vista and UI-View32
Hello Roger,
when Microsoft offered the ability to download the Beta 2 version of
Windows Vista, I got my copy and installed it on a DELL Inspiron Notebook
with 1.2 GHz Pentium M and 512 MB Ram. The OS itself worked without
problems and so did UI-View32. I tested UI- View32 V2.03 with FlexNet for
several days and did not experience any problems. I don't own the final
release of Vista, so I could not test APRS with the official version though
I don't think it will make problems. If so, you could test the
"compatibility mode" (which is known from Windows XP).
After installing I just had difficulties with serial port or soundcard
allocation and besides, UI-View could not connect to any APRS-IS server
because I didn't start UI-View32 and FlexNet with admin permissions.
Hope I could help.

I think that I would disagree a bit with your logic. If the DigiNed (or
other) digi was a "low level" digi that could help mobiles make it to a
higher elevation WIDEn-N digi, then I would agree with making it a WIDE1-1
only digi. I believe your intention was to move it to a higher location a
few hundred metres up. For now, it will be the closest thing to a "big
footprint" digi that you will have around there. Looking ahead to when it
is in use and mobile stations are passing through, if it was a WIDE1-1 only
digi, it would ONLY help out those mobiles if they started their path with
WIDE1-1. If you make it a WIDEn-N digi, it will help out mobiles that start
their path with either WIDE1-1 or WIDEn-N.
