Preamp - Universal Mono Preamplifier Kit This kit was designed to suit different audio-applications where an insufficient input signal is available.
40 Meter Transmitter Kit w/Case (Includes 7.040 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.	41-LED Star VU-Meter with Built-In Mic and Line-In (Fully Assembled) This LED VU-Meter incorporates a highly sensitive built-in microphone which allows the circuit to capture the ambient sound and to operate without requiring a wire connection to your stereo system.
