World’s Smallest Stand-Alone ATU!
The Elecraft T1 is the only automatic antenna tuner that’s sized to match today’s small QRP rigs. It’s one-fourth the size of most other compact ATUs. And at just 5 ounces, the T1 is the ideal backpacking accessory.

Use with any Low-Power Transceiver
The T1 can be used with any 0.5-W to 20-W transceiver covering bands in the 160-6 m range. This includes kits, home-built rigs, and commercial transceivers such as the FT-817, IC703, Ten-Tec Argonaut, SG2020, etc.

Quick, Convenient, and Accurate
The T1’s 7-inductor, 7-capacitor L-network provides a wide matching range, and its re-tune time from memory is just 1 to 2 seconds. Equally important, the T1 always tries to achieve a 1.0:1 SWR—it doesn’t stop at 1.5:1 or 2.0:1 like some tuners. You won’t even need to change modes to tune. You can use SSB voice or a keyer as well as a constant carrier (AM, FM, CW, etc.).

FT-817 Remote-Control Option
For even greater convenience, we offer a "smart" remote control adapter for use with the Yaesu FT-817 . On any band change, the adapter's microcontroller sends band data to the T1, which quickly recalls the appropriate network settings. Imagine instant QSY without the need to transmit-less QRM, less hassle! (See drawing below.)

Factory-Assembled or Complete Kit
You can purchase the T1 assembled and tested, or as an easy-to-build kit. Our professionally written, fully illustrated assembly manual provides step-by-step instructions, and no alignment is required.

Unsurpassed Technical Support
If you have any difficulty, our technical support via telephone and the Internet will get your T1 up and running quickly. You can also get answers to nearly any question day or night from the helpful, tech-savvy hams on our e-mail user group.
