These little rigs are burning up the airwaves as young and old alike are rediscovering the fun in building their own equipment! Our detailed, step-by-step instruction manuals make building an enjoyable and rewarding experience. You‘re guided carefully to the completion of a unit that not only works, but will provide hours of operating pleasure. These trusty and proven Ramsey all mode mini rigs are routinely used worldwide by hams of all ages. You‘ll find you don’t need high power - K71RK worked and QSL’d all states, plus global DX QSOs from Argentina to the former USSR—with only 2 mW! You don’t need hundreds of watts, thousands of dollars or massive equipment, you‘ll find it’s more fun with less! These little receivers are based upon the hot Signetics NE-602 that we read about almost every month in all of the ham magazines and handbooks. The receivers are true superheterodyne direct conversion - a simple design that does not require the use of fancy IFs, RF filters, or exotic mixers, in short, the ideal design for easy hobby building. Only recently have high performance ICs become available that enable such circuitry to be constructed. Beginners can easily build these receivers. And, experienced amateurs and QRP enthusiasts can use them as a reliable, economical, basic foundation for modifications. Our single PC board has plenty of room for lots of modifications and hook-ups, tinker to your hearts content. Suggestions and technical info are included in every receiver manual. Isn’t this what ham radio is all about? Operates on 9 V battery (not included). Optional case size: 5”w x 5 1/4”d x 1 1/2”h.
