20 Meter Transmitter Kit w/Case (Includes 14.060 MHz XTAL)

These nifty little CW transmitters are practical and economical take-along rigs for trips, camping, teaching or just amazing yourself with just what a watt will do! With exceptional manual of over 20 pages, the detailed step-by-step instructions guide you to a perfectly operating finished transmitter. The rigs use a standard crystal that is connected into a VCXO circuit - which means that you can tune around the crystal's frequency by up to 20 KHz - thus giving you stable crystal control while still being able to tune around! A front panel switch lets you choose between two crystals, we include one, you can add another of your choice. A built-in T-R switch allows break-in operation. Of course, these transmitters interface perfectly with our QRP Mini-rig receivers and our CMOS CW keyer! And for the real ham, there's plenty of room inside the custom case for your own circuit modifications and experiments, these little rigs are often the heart of many QRP operator's stations. Modify till-the-cows-come-home, or just use em as they are - these little rigs pack a lot of performance into an economical package. Runs on 12 VDC at 200 mA.

You get a lot for your money with any one of these dual-conversion FM receivers. In just one evening of building fun, you can be snooping around the band monitoring the local repeater, checking-out new bands, or even eavesdropping in on the local police and businesses. 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 are 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 FR-146 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 can't be beat. Kit includes detailed step-by-step manual of 28 pages that carefully guides you to a finished working radio. Runs on 9V Battery.

Need a little extra boost for your QRP rig? This nifty little amplifier may be all you need. Believe it or not 20 watts is only 7db (about one S unit!) less power than a full sized commercial transceiver. These compact amplifiers are easily driven by any of our QRP transmitters or any other unit in the 1/2-2 watt range. Advanced power MOSFETs are used for the utmost in efficiency and purity, while a multistage low pass filter is used to assure a clean signal output. Power required is only 12 VDC at 2 to 4 amps, depending upon power output. Complete step-by-step instructions are provided which makes building the kit a breeze. The amplifier works well for all modes: CW, SSB and AM. Select the band of interest to you and don?t forget our custom matching case set for a complete station look.

Put some new 'ears' on your rig with one of these hot little preamp kits. Their high gain combined with low noise will improve most any receiver. Fully protected against overload and designed for low current and stable operation. They employ high Q tuned circuits which restrict out-of-band signals which can cause intermod blanking and over load of your radio's front-end. Don't be misled by GaAs FET claims! The cheap dual-gate FETs (manufactured for TV tuner usage!) used by others just don't come close to the performance of these preamps designed with NEC microwave transistor devices. Gain is typically 16 to 20 dB and noise figure is 1 dB @ 2 Meters, 1.2 dB @ 220 MHz, and 1.4 dB @ 440 MHz. Compact design or easy installation into most any rig. Operates on 12 to 15 VDC.
