It's definitely nice knowing that I'm only a few steps away from the machine
running UI-View, but it's more reliable than the Energizer Bunny. It just
keeps on going and going.

Hmmm... I'm having a bit more success. The desktop machine that's running
the IGate performs quite a few other functions, but I'm probably not working
it too hard. On the other hand, I also run UI-View on a laptop that I
routinely run way too many programs on. I've sometimes had to do a reboot on
the laptop, but I don't blame it on UI-View. It's probably more to do with
the dozen to two browsers I'm running (pre IE7), a database or two, a few
other programs, a text editor, an HTML editor, a few copies of PuTTY, an
email client or two, a mapping program occasionally (in addition to UI-View
which us using PMapServer 7 / PM7), sometimes a terminal program or config
program for a TT3 or OT etc. I don't complain too much if I have to reboot
the laptop every week or two whether it needs it or not. Of course, if I
take it somewhere, it usually gets shut down for a few minutes while it's
going out to the truck.

That sounds reasonably stable!

I know what you mean there. They can go months without needing a reboot, and
that's usually because of some update that was needed.

Hmmm... if they are identical in other regards, it sounds like you might
have some hardware issues.

That's too bad about the radio, but it sounds like you got quite a few years
out of them. The next one will probably have a time-out timer.
>So the path should not be able to alter...
For flexibility, it would be nice to adjust the path, but if it's generating
an object to advertise a repeater, the ideal would be (as Bob mentioned) if
it was up at the repeater site or right at a digi site with similar coverage
to what the voice repeater has.
>Anyhow people can still send out objects with i.e ui-view
>and APRSTracker.
Yes, but as Bob mentioned it would be at the path as specified in the
station setup. I sometimes put out objects from here with my usual one hop
path of WIDE2-1. There are occasions when it would be better if they went
out with no path.
>So maybe LA3QMA to APU25N via QRT is the way to go...

The destination isn't going to make any difference how far the object goes,
but the path will of course. When it comes down to it, if an existing digi
has a similar footprint to the voice repeater, it would be the ideal place
to beacon the advertisement with no path. As Bob also mentioned, a tracker
right at the repeater site could also be used. An add-on to do it from a PC
will sometimes be the right solution in other places. As you pointed out,
any UI-View (or other client) can put out an object, but at the station's
default path.

Subject: [aprssig] Feeding impedance QUAD antenna
Gudday
I am now up to the stage of feeding my 8 element quad for 145.825 MHz.
I have been doing some reading and I see that most talk of a 100 ohm feed
point.
The most popular seems to be a 1/4 wave section of 75 ohm cable in series ?
Does this look right:-
Freq = 145.825 MHz
1/4 wave in coax = (200 / 145.825 MHz) /4 = 34.28 cm's of 75 ohm cable.
Cheers

Depends on the velocity factor of the Q section.

yes but remember no upgrades etc its better to close security bugs in
the firewall between the windows machine and the net. not sure if this
stability had been so high if i was using the machine for other things.
But i had one or two times the TNC on the TM-D700 stopped. Overkill to
use the tm-d700 but as i'm using the radio from work then the main band
can do some work when i'm not using the UHF hehe
Running UI-View as a DIGI and IGATE. But now we got some snow :o( so the
planed digi is postponed yet again.

Have found out that the upgrade on windows doesn't use the same drivers
on the hardware.
Strange... But a stable windows is stable... but when its start acting
veird then its no hope and i think its faster to reinstall a Ghost image
than to try to fix drivers etc.

hmm
think i'm going to ask the Elcom dudes if they can implement something
like this in the DIGI.
Its possible to enter 4 different DIGI comments and with 4 different
paths. So maybe a beacon with another symbol could be possible.
Offtopic: hows the status on TM-D700? Here in Norway its not possible to
get one due to some new "eu" rules. They are allowed to sell what they
had in the shop in 2006.Probably have to buy from US but even with taxes
and transport its cheaper that way.
