What is the BEST way for one to try to do this again. I would like to give
ti a try but have no clue as to how to make this happen.

Either I've been kicked off the list or there may be distribution
problems. This message is just to see if I get an acknowledgment from
Lyris.

Nope. It looks as if Stan, WA1LOU, has changed my settings to receive no
email and he changed my password. Now, I don't mind him suspending me
from the APRSSIG list if he feels there's a need for it, but he should
at least inform the folks he does that to. These type of games are,
well, rather childish, no matter what you think of the folks he does
that to.

What's available out there for low-cost, lightweight 2-meter FM
transmitters? I've seen kits for $70 or so, but I can get an Alinco DJ-S11T
on eBay for $50 that weighs less and has more features. What I really want
is something on the order of 50-100 mW output in a matchbox size package.
It only needs to operate on one frequency (crystal controlled?) and handle
Bell 202 AFSK. Any suggestions?
I was looking at Analog's direct digital synthesizer chips a while back...
the AD9851
(http://www.analog.com/UploadedFiles/Data_Sheets/41539448AD9851_c.pdf) has a
maximum frequency of 180 MHz and as I understand it can be used as a FSK (or
CW, AM, FM, or MSK) transmitter. What would be needed besides a final
amplifier stage to make a usable data transmitter out of this? At $25 a pop
it's not the cheapest way to go, but it'd be more flexible than a crystal
rig.

Where it actually landed depends on the altitude of the landing point.
Here are my guesses of the landing spot relative to the last reported
position of 3831.94N and 8012.77W:
Altit DR dist Estimated position
----- --------- ------------------
3000' 1.5 mi NW
2400' 2.0 mi NW
1800' 2.5 mi NW
1200' 3.0 mi NW
Another crisis came up, and so I dont have time to do the calculations to
give the exact LAT/LONG coordinates. Maybe someone else...

Icom 2AT's, RadioShack HTX-202's are pretty cheap (25 dollar range)
Motorola HT220's in the 10 to 15 dollar range, MT500's in the 25 to 30
dollar range..
Depends on what you need.

A gentleman in the area (Bruce - W8AOK) did some RDF today in an attempt to
find the balloon and his very detailed summary is at:

If anyone on the list knows of someone who might be able to use this
information and assist in the recovery, please let me know!

The GPS batteries should have died late last night, so now it is only the
status beacon (which contains my email address and telno) that is going out
every 6 minutes or so (time interval equal to four of the original posit
transmissions). Also, the guy who is searching doesn't have any packet
equipment at all, but has a 2m radio in the car. So he's hearing the data
burst every six minutes and from that we're assuming that it is the balloon.

If the system is still sending out a beacon, all that is needed is one
decoded packet to get the Lat/Lon coordinates. If the person searching does
not have a TNC, then a good clear recording of the signal using a tape
recorder could possibly be used to decode that needed information. With the
Lat/Lon from the payload, it then becomes easier to identify the location
provided it is still sending valid packets with positional information.
Without a TNC or something to decode/record the data there is no way of
telling if you are listening to the correct transmitter or not. There are
other APRS signals to be heard along those ridges on CR15. Just one good
decoded positional packet is all that is really needed to get a good fix on
the location.

Fine job and wonderful report, Bruce W8AOK! Great work (and FB on the URL
for your fine website showing at http://www.qrz.com/detail/W8AOK ).
I have Delorme 3-D Topoquads (for California) here, and I'd be happy to be
able to produce even half of Bruce's great report. That stuff from Scott
N1VG last night was awfully spectacular too!
Now, all you guys need are a few reinforcements on the ground. hi I hope
those hams can arrive soon enough.

I'd be very interested in HT220's for $10 each, I'd take several right
now. Your prices seem pretty low.

"What I really want is something on the order of 50-100 mW output in a
matchbox size package."
Ya'll must be talking about the BIG matchbox, I was thinking the smaller
one was what he was after.
MANY years ago there was a product advertised in 73 magazine designed to
plug into the back of your HF rig and let you wander around the house
listening to the audio on your HT. The whole thing was built into a
1/4" phono plug with a wire antenna on the back of it. I tried and
tried to track down the former manufacturer to no avail, nor could I
find one to tear apart.
There are some fox hunt kits you might look at, I've seen some of those
very low power and small enough for a matchbox, of course I can't
remember where now....
