Oh yeah Start punching holes in other peoples vehicles. THATS going to
make us popular! And gee, what if the Intergalactic Confederation sends
a ship to help, and their Anti-matter generators don't use APP's....
Nothing is going to cover all situations, but going with a standard
_minimizes_ the amount of in the field jury rigging you have to do, (and
under those conditions, it's a matter of WHEN not IF you're going to
wire something up backwards). In your scenario, run the wire, crimp on
some APP's at the radio end, (or wire nut a pre-wired pig tail with APP
on one end and bare wire on the other, and yes, I carry the stuff to do
this in my kit) and the guy with an APP adapter wired into his radio
that relieves you can unplug your stuff and plug his in with no further
wiring.
Gang, this is way off topic, suggest we move it to something like the
ARES/RACES list before Stan makes US non-standard!

About the only online balloon FAQ I know is here:

There's also another good write-up here:

Forgive what may be a naive question ..
what's the best way to afix a wire to the power pole contact? solder,
crimp, solder and crimp?
I guess it depends to some extent on the wire gauge, e.g. 12 vs 18, right?
For example I have a tough time trying to get solder into the barrel when
working with 12 gauge.
I've also been told that doubling over the end of a small gauge wire helps
fill the barrel more completely and makes for a tighter fit. Yes?

There are several groups on Yahoo devoted to Ballooning. Do a search on
Yahoo for ballooning and there are several groups on near space ballooning
etc. Too many for me to list right now. Also check out www.nstar.org they do
regular balloon launches with APRS packages.

I've bought a cheap $5 crimper from our local "chinese tool store". Works
like a champ, very heavy cast parts (not your typical "stamped from a flat
sheet" crimper. I use this for 12 and 14 gauge wires. One problem I've
had with 12ga wire is that the jacketing is so thick it doesn't want to fit
into the PP housing. This has caused me to not be able to push the contact
in far enough that it catches on the hook. When mated the contact will
slide back into the housing and make intermittent contact. This particular
problem caused me to have intermittent GPS resets (particularly on bumpy
roads).... moral of the story: push the contact in until you hear the "click".
For smaller sizes, I use a pair of vise grips. You have to be very
careful... but you can squeeze the power pole contact along the edge of the
seam of it's barrel causing 1/2 of it to collapse onto the wire. It will
change from looking like an O to looking like a G when viewed from the
end. Then, switch the vise grips to the other side and collapse the other
1/2 on top of the first 1/2. from the end, it ends up looking like the @
symbol.
For god measure, I *always* heat and flow some solder on any sized
wire. My belief is that it prevents corrosion from interfering with the
wire and the contact. Those contacts flow solder like crazy, so be careful
not to let it flow out onto the contacting surface.
Just to contribute my bit 'o noise to the thread... a pair of power poles
w/ LED and resistor to indicate polarity is a good idea to keep in junk,
err jump box. Cigarette lighter with 12ga wire and power pole is a life
saver, ring lugs and power pole on a short length of wire are another way
to get power... most cases it is possible to run a wire along side of
engine compartment out behind the back of hood (near windshield), over to
the passenger door and in via the rubber seal on door. (watch out for
wire pinch hazard around the hinges)
I saw one ham here questioning the usefulness of a "standard connector". I
have to wonder if this is the same sort of person who has a nut driver for
each size socket. Myself, I prefer to carry a ratchet , some extensions
and a set of sockets. And if I don't have the right socket, I know that
since 3/8 square drive is a "standard" I can borrow one from someone....
same goes for power connectors.

Get a Klein Tools crimp plier (model 1006). ~$20. MAKE ABSOLUTELY SURE you
push the indent in on the side OPPOSITE the 'seem' in the anderson lug..
WORKS GREAT.. I've made hundreds with this tool. No solder necessary.

I always solder. You can't re-use a crimped connector.

Heat the pin, then touch the solder to the wire, just behind the connector.
It will flow in and fill nicely.

Yes.

Does anyone have an up to date copy of symbols.bmp and symbols2.bmp that
has the new NWS icons and other updated icons for APRS+? I was advised
I can manually edit them, but I thought I read someone was keeping up to

Many times, a crimp and solder connector is required for many mil spec
applications. Although soldering makes
a good electrical connection better, it can lead to hard joints which can
fatigue and fail....just something to be aware of
and in many applications, not a problem.
Telcos have gone away from clamping type connectors and now use crimp
connectors with properly sized crimp dies that fit the connector and wire
gauge. None of these connections have been soldered and 15 plus years
(after the spec change) proves it is not a problem to just crimp this type
of power connector. I must say that this in a clean, none moving
enviroment.
