Get in on the fun of radio direction finding (RDF) with this
super kit ! The latest in affordable Doppler direction find-
ing equipment available in a complete kit form ...this one
even includes the receiving antenna assembly!
A must for the “fox hunter” at an unheard of price! Radio
direction finding is a fascinating hobby and is becoming
more and more popular in today's portable world.
With the increasing number of intentional jammers and other unknown transmitters around, Doppler DF locators have
become the rage with a display that gives you a direct bearing on the location of the transmitter. Pretty neat trick consid-
ering you don’t need multiple separate receivers at different locations to triangulate on the mystery transmitter!
The kit includes the Doppler Direction Finder display unit and all the parts necessary to build your own four point, 5 piece
magnetic antenna assembly for easy setup and use. Operates on 12-15VDC and includes a matching 12VDC power plug
for custom integration and connection into your vehicle or portable power supply. Easy to hook up to any FM receiver.
Transmitter (the object of your DF'ing) need not be FM, it can be AM/FM or CW.
Requires only a connection to your receiver's speaker jack and radio's antenna. The whips can be cut and optimized for any frequency from 85-1000 MHz. An easy to build, reliable
kit that compares most favorably to commercial units costing upwards of $1000.00! Comes complete with matching case, 12VDC plug, magnetic antenna kit with cables, and a com-
prehensive instruction manual.
(Editors rule of thumb: always look across the street for a guy on a lawnmower before you take the picture!)

Doppler Direction Finder
There are no short cuts taken in the design of these units, sensitivity is equal to full size monitor receivers or scanners. Schools,
scout troops, clubs and hobbyists use these receivers for teaching, monitoring, and just plain building enjoyment. Any one of
these little receivers is ideal for easy chair listening and with no big clunky box and wiring to aggravate the XYL!
All four receivers can be tuned outside of the intended amateur bands. For example, the FR146 two meter receiver will tune any 5 MHz segment
from 130 to 180 MHz. Choose your band and enjoy FM repeater and simplex monitoring on a budget! Help a newcomer discover the 220 MHz novice
band. Listen in on exciting 10 Meter international FM action. Rediscover the fascination of 6 Meter sporadic E band openings and uncrowded new FM repeaters. For a professional
finished look, our matching case and knob set is included. Kit includes detailed step-by-step manual that carefully guides you to a finished working radio. Runs on a standard 9VDC
battery (not included). Case measures 5”W x 1½”H x 5¼”D.
