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 up to four bands into our affordable, easy-to-build K1-4 transceiver. You can order the K1 as either a four-band radio (K1-4) or a two-band radio (K1-2). The new four-band K1-4 covers 40, 30, 20, and either 17 or 15 meters. (All band parts are supplied with the kit and 17 or 15M are chosen as the last band at build time.) You can also upgrade the K1-2 to a K1-4 by purchasing the four-band KFL1-4 module and replacing the KFL1-2 in your original K1-2. The KFL1-2 two band module covers your choice of two bands (80, 40, 30 20, 17 and 15 meters available). Combining a K1-4 with an extra KFL1-2 band module on 80 + (15 or 17M) gives you all six bands on your K1! Both module types simply plug in to the K1's main board, internally, and you can swap either type in at any time.
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.

An HF radio you'll never leave at home Looking for adventure? With its low receive-mode current drain of under 60 mA, the K1 is a natural for portable operation. Add the internal battery (KBT1) and internal auto-tuner (KAT1) to create a true, all-in-one-box station! 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.) |

K1
Backlight Mod Kit (manual,
pdf) |
Ideal
for first-time kit builders
We use only through-hole components in the K1 to make construction and testing a breeze. And our wireless design methodology eliminates nearly all point-to-point wiring. Finally, the front panel and filter boards plug directly into the RF board to form a clean, rugged assembly. You'll be tempted to leave the cover off to admire your work!
You also won't need a lab-full of test gear to align the K1. It includes a built-in digital voltmeter, wattmeter, and frequency counter.
You'll find the K1 manual easy to follow, with step-by-step assembly, clear illustrations and photos, and modular checkout of each major section. There's also a detailed theory of operation section, as well as a complete troubleshooting guide.
Strong
Customer Support
Our technical support via telephone and the Internet will get your Elecraft K1 up and running quickly. On-line manuals, frequently asked questions (FAQ), application notes and our user group e-mail list make building the K1 a great experience.

KFL1-2
Additional
2-Band Filter Module:
The original KFL1-2 gives you two bands of your choice (80, 40, 30, 20, 17, or 15 M). Combining the KFL1-2 with a K1-4 gives you all six of these bands. Swapping band modules takes only a couple of minutes, even with the antenna tuner and/or internal battery installed. |
|
|
KFL1-4 Additional 4-Band Filter Module: The new KFL1-4 upgrade packs four bands into your K1 (40, 30, 20, and 17 or 15 meters included. Choose 17 or 15M as the last band at build time). |

KNB1
Noise Blanker The KNB1 reduces impulse noise including noise from automobile ignition and noisy power lines. |
|
|
KAT1 Internal Automatic Antenna Tuner
The KAT1 packs a fully-automatic tuner into a small module that plugs directly into the K1's Filter board, with no wiring. It allows you to connect most end-fed, random length antennas directly to the K1's antenna jack--even with no feed line. Also works with coax-fed antennas. |
|
|
KBT1 Internal Battery Adapter
Ideal for those who like to travel light, the KBT1 packs 8 AA cells into your K1 and still leaves room for the ATU, noise blanker, and speaker. You can operate for 5 to 10 hours at the 2-3 watt level using either NiMH or Alkaline cells. |
|
|
KTS1
Wide Range Tilt Stand
The KTS1 allows you to set the K1 on nearly any rough or irregular surface and aim the front panel upwards for easy operation. You can also attach a lightweight keyer paddle directly to the stand, eliminating the separate heavy base. Includes short arms for regular desktop use. |

This attractive, modular project enclosure is the same size as the K1 (2.2"H x 5.3"W x 5.6"D). It has the same color and textured finish, and includes 8 of our versatile "2-D" fasteners, providing several ways to mount PC boards of your own design. |
