Someone (everyone) send/post suggestions on some kind of light weight
electronic recovery assistance device. (The wind is KILLIN' me here on the
mini dry lake) "UP UP and AWAY" is beginning to have a whole different
meaning!
It's gotta' be light weight (duh) C engine-able.
I can solder a little but would consider just ordering one if they are
available.
Where?
How much $?
Working distance?
Line of sight only?
Payload weight #?
Thanks in advance

I suggest you look at Pete Kerchkoff's tiny 70cm RDF.  I've built one and it
is small enough to fit inside a 29mm tube.  Smaller if you use a 6-volt photo
battery instead of the 9 volt radio battery I use.

Pete's project page is at http://www.tfs.net/~petek/RDF/70cm.html

I adapted the original design to use the simpler  oscillator circuit from
Pete's sonic beacon project instead of the morse code generating PIC chip.

Good luck!  This is a really cheap way to get into Radio Direction Finding.

The sonic locator beacon is also a good & simple project.

Transroc 2 will do if your rocket has a bt-60 or bigger body tube.They are
about $30.
It uses a beep to tell you whan you are close to your rocket.
You can find it at your hobbyshop or order it from Estes.
Any more questions? Range?

   The Transroc 2 is only a sonic device, ie: a glorified beeper.  WAY
over-priced for what you get.

Not exactly.  The "transmitter" is a simple
sound alarm beeper.  The "receiver" is a
simple microphone that picks up ANY
sound.  It's pretty bad in any wind and
has little to no range.  I've regretted buying
one.

Keep'em flying.
It's not what you got, it's what you do with it.
Try helping other's instead of hurting them.
Instead of fighting over an inch of ground
lets move out into space & live in peace.
Home is where the heart is.
Keep'em flying.

Oneal,

If you are among the electronically inclined you could build your own FM
tracking transmitter, check out the site at:

http://www.darkportal.com/cc/circuits/circ0054.htm

The parts will cost you less than $20.00 at Radio Shack,
including the circuit board.

Also, check out Jerry Baumeister's site at:

http://www2.crosswinds.net/oklahoma-city/~jbgizmo/

for a small model rocket sonic locator that you can build,
tips on making a directional locator from a small hand held FM radio
receiver, and radio tracking transmitter kits.

I also heard on RMR that pages 37-42 of the July 1999 issue of Popular
Electronics contains an article titled:
Experimenting with Small FM Transmitters.

I have been involved with model rocketry for many years now.  I really enjoy
participating in this newsgroup and reading everything that everyone has to say.
As discussion groups go, this one, I think is one of the better ones I've seen.
But, sometimes I get frustrated with the way these newsgroups work.  If I post a
message in DC, my friend in Boston rarely ever gets to see the post on his
newserver; moreover, I can't find any of my old posts on this server.  I don't
know what determines when, or if, my post gets to other newsgroup servers and
its very FRUSTRATING..  But, there is a new discussion on the subject of model
rocketry at a website at
http://uc1.groupserve.com/commentlist.jhtml?dn=2342
To me, its easier to use than a newsgroup, and, most importantly, everyone sees
your posts everywhere in the world at the same time as soon as you post your
message!
