* 4 Transistor circuit, oscillator, RF amp chain, and clean keying stage!
* RF output approx 1 Watt (.75W for QRP-20)
* Pi-network output for good matching and harmonic suppression!
* Provision for two internal crystals, front panel switching!
* VCXO tuning, frequency can be tuned approx 7KHz around xtal freq.
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 included 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 or the optional AC125 power supply.
