Ozark Patrol

Kitted and Offered For Sale By
The Four State QRP Group

Designed by David Cripe, NMØS

Introduced at OzarkCon 2014, this kit was designed in homage to simple beginners regenerative receivers of a generation ago.   Many current hams and radio enthusiasts were introduced to the hobby by building and listening to such classics as the Radio Shack Globe patrol, or the Knight Ocean Hopper.   It has been many years since there has been a simple shortwave receiver kit on the market, so the Ozark Patrol is offered so that the builder of today can relive the excitement of tuning in the world on a simple receiver circuit.

The Ozark Patrol circuit is a two-band shortwave receiver, using only three NPN transistors in its circuit.   It employs a reflexed regenerative detector to maximize gain from its simple design, followed by a two-transistor audio amp.   It is capable of operating from a simple wire antenna.

This kit features a pre-drilled and silkscreened circuit board front panel with a total of 38 through-hole components mounted on pads etched on the opposite side.   Component values and reference numbers are silk screened by each part location for fool-proof assembly.   This style of PC board was invented in 2003 by our own Joe Porter, WØMQY as an optional board for the NJQRP RF Sniffer, a field strength meter designed by Joe Everhart N2CX.   Click here for a picture of that board Since WØMQY lives in Pittsburg, KS, the board design was dubbed the "Pittsburg" style.

NMØS has previously employed silk screened panels in the Cyclone, QRPometer, and the 4S-Link.   Refer to the Ozark Patrol photo page for more details.

First time builders please note: With a very low part count and the Pittsburg style pc board, this kit is easy to build.   There are NO SMT parts, and the components are widely spaced on the board.
