elecraft K1 The K1 portable CW Transceiver
HF operation is more fun than ever these days–five watts is all you need to work worldwide DX. That's why we've packed two bands into our affordable, easy-to-build K1 transceiver. With your choice of  *two* HF bands  (80, 40, 30 20, 17  and 15 meters available) you'll be able to go where the action is, day or night.

I Can´t Believe It´s a Kit!

As suggested by the 9-volt battery in the photo, the K1 is small–only 2.2"H x 5.2"W x 5.6"D, and weighs 1.4 pounds. Yet we've included many features you'd expect in a desk-top HF transceiver, including RIT and XIT, full break-in CW, memory keyer, three crystal filter bandwidths, configuration menu, speaker, and digital display. The K1 is styled to match our all-band K2 transceiver, with the same “look and feel,” attention to detail, and operating mojo you'd expect from Elecraft.

Mike Elliot, W8KKR:  "My son, KC8MIG, built a K1 and was very impressed. As the ex-chief engineer of Heath, may I offer my congratulations for a kit job well done -- and I should know!"

An HF radio you'll never leave at home

Looking for adventure? With its low receive-mode current drain of under 50 mA, the K1 is a natural for portable operation. (You really can power it from a 9-volt battery, in a pinch, thanks to our low-dropout 8-volt regulator.) Hikers will appreciate our unique Wide-Range Tilt Stand (model KTS1), which supports the radio at any desired viewing angle. (Photo shows ground mount configuration.)
