Walston radio locator for planes/rockets

Sold pending payment

Walston radio tracker for model airplanes or rockets

The receiver with the directional YAGI antenna allows you to locate the
transmitter by listening to the volume of the chirping signal as you turn
the antenna.

It has a range of 2+ miles on ground and 20+ miles line-of-sight in the air.

This is an older model that I had stored away for about 10 years. New
Walston systems have slightly smaller receivers, but their operation is
essentially the same.

The transmitters are about an inch long and weigh 3.5 grams with
batteries. Each transmitter has a 19" long braided wire antenna. One
transmitter is channel 1 (219.596Mhz), the other is channel 2 (219.49Mhz).

I used this system on several occasions to locate high-power rockets in the
Arizona desert. One time, I didn't secure the transmitter inside the rocket
very well, and it got separated from the rocket. I located the transmitter,
but lost the rocket. After that, I made a carrier from a .5" diam. launch
lug, which I glued inside the body tube, to hold the transmitter.

This would be ideal for a rocketry club to loan to members when launching
high-altitude rockets. Or for RC aircraft/soaring/FPV enthusiasts who have a
lot invested in an aircraft and don't want to lose it. I have been through my
born-again rocketeer days, and I have moved on to RC helicopters now, so I
don't need a long-range locator anymore.

Includes:

1 3-channel receiver with built-in speaker (1.5"x2"x5")
1 Battery Holder - 6xAA cell
1 Black leather carrying case with belt loop, for receiver and battery holder
1 Earphone for optional private monitoring
1 Folding hand-held YAGI directional antenna (about 2'x2'open, 2'x 6" folded)
1 3-ft coax cable to attach antenna to receiver
1 Canvas carrying case for antenna (not shown in photos)
2 Transmitters, one channel 1 and one channel 2

Included instruction sheets:

-Folding/Unfolding of the Antenna
-Battery installation
-Receiver operation
-Transmitter operation
-Directional orientation of the antenna
-How to Get the Most from your Retrieval System

I just now tested the receiver and both transmitters, and their signal is as
strong as when I first used them.

No batteries are included. You need 6 AA cells for the receiver and
2 x #392 button cells for each transmitter.

If you buy this and you are not happy with it, I will gladly refund your money,
minus shipping cost, upon its return to me, within 30 days.

A new system like this retails for about $800.00. See the Walston site here:

http://www.walstonretrieval.com/section-1.htm

I am asking $395.00 shipped, to anywhere in the U.S. only.

PayPal preferred, but I will accept a check if you can wait 10 days for it to clear my bank.
