Another way is to use a scanner and a scope. In my case I installed a jack
in my old RS scanner connected between the top of the volume control and
ground. That way the output is not affected by the setting of the control.
To use it, monitor a station thought to be reasonably close in deviation
(someone suggested a police station) and note the signal level on the
scope. Now set your equipment to the same level. Two way radio shops have
FM signal generators/service monitors that would be ideal for calibrating a
scanner/scope combo, perhaps you know someone that would do it for you. I
wish I did.

It's easy for UI-View32 in KISS mode to be setup as a digi, a fill-in digi
or a full digi (instructions below). But yes, that full digi sysop does
have to choose between whether WIDEn-N or TRACEn-N will be fully traceable
in their UI-View32 digi, but the other choice can still _operate_ correctly
too (except for producing the traceability in the digipath history). That
change of which (WIDEn-N or TRACEn-N) is traceable can then be readily
phased in as more and more users use WIDEn-N. hi

Commercial AVL is insane, this thing was still $1,800.00 the last time
I checked into it, and the digipeaters, and base receive units cost the
same too.

Sorry, no, you can't.
Your RELAY packet might not be processed by any digi in some areas, because
the sysops in that part of (somewhere) have set WIDEn-N and SSn-N only, no
ALIAS of RELAY.
Some sysops have decided that we don't care that the neighbourhood (on the
same or the other side of an international border) are supporting RELAY
(maybe also WIDE1-1) as fill-ins, and that visitors coming by car, crossing
international borders without any delaying stops (unlike at the US/CAN
border), don't change their settings while driving.
I don't know how things are in SP, but I know that TF and some western
parts of LA are using the new north american system, the rest of LA and
probably SM and OH, and probably most of continental Europe, are accepting
both TRACEn-N and WIDEn-N, and RELAY, but OZ sysops are insisting that any
WIDE packet isn't retransmitted (i.e. RELAY,TRACEn-N or TRACEn-N only).
This is in my humble opinion a matter for IARU region 1.

No, WIDEn-N doesn't necessarily work here. I referred to Denmark (OZ)
where they actively STOP any digipeating on WIDE (quite a few OZ digis
beacon "NO DIGI ON WIDE")

Hi All
======================
European APRS Guidelines
======================
http://www.apritch.myby.co.uk/uiview_neweu.htm
This page contains guidelines on maximising the capacity of our European
APRS network (144.800Mhz).
======================
Fixing the APRS Network
======================
http://www.apritch.myby.co.uk/uiview_newn-n.htm
The APRS network in some parts of the USA suffer from major congestion.This
is mainly due to the nature of the original design of the APRS network
combined with a dupe check issue found in stand alone KPC3's (apparently).
I hope that helps...

I would opt for US standards in EU, i.e. WIDEn-n, SSn-n and just WIDE1-1 for
fill up digis. Main reason is to keep some standards for all kinds of APRS
software and hardware. With such universal standards is much more clear how
to setup station.
In Poland we use WIDEn-n (traceable), SPn-n and still RELAY because of
compatibility with neighbor countries, but we are ready to switch RELAY to
WIDE1-1 any time.

Subject: Re: [aprssig] APRS For EmComm ?
I've written a scipt that runs in linux and coverts rino gps data to aprs
data. It acts as a go between between rino and xastir. It requires that
you have one rino unit as a base station that collects position reports
from over the air. They are then downloaded and sent forward to xastir.
We were able to track 5 users during a recent fire in a textile plant that
took DAYS to put out and required the town be evacuated.
I also expect (but have not used in a drill yet) to be able to create an
object in aprs that represents a truck heading into an area by giving it a
speed and heading. This way we can keep tabs on where that truck with
generators and water is after the hurricane.

I've tried from two different TCP/IP connected Xastir systems and gotten no
response. Does your system parse Base-91 compressed positions? Perhaps it
doesn't know where I am.
