Reviews Summary for Elecraft T1 Miniature ATU for all Low-Power Transceivers
Elecraft T1 Miniature ATU for all Low-Power Transceivers Reviews: 52 Average rating: 4.7/5 MSRP: $135
Description: This may be the world's smallest high-performance, stand-alone ATU. At just
4.4 x 2.5 x 0.9 inches, and weighing only 5 oz., it's about one-fourth the size
and weight of other compact automatic antenna tuners.

The T1 has 7 inductors and 7 capacitors to provide a wide tuning range. It
can be used with any 0.5 to 20-watt transceiver or transmitter, and can be
tuned in any mode, even SSB voice. Many L-C settings are saved in the unit's
EEPROM for quick re-tune (typically 1 to 2 seconds).

An internal 9-V battery powers the unit, and battery life is excellent thanks to
the use of latching relays and auto power-off after each use. There's zero
power consumed except when actually tuning.

There's a "smart" adapter cable available for the Yaesu FT-817. This
convenient accessory allows the T1 ATU to track band changes made at the
transceiver, recalling per-band L-C settings without the need to transmit.
Product is in production.

Nice little tuner, easy to build  Time owned: 0 to 3 months
I built mine from a kit a couple of months ago, and use it with my Xiegu X1M Platinum. It was an easy kit to build (all components that need to be installed are through-hole, you just need to make sure the leads are clipped off FLUSH with the board surface after soldering). All SMD components are already installed when you receive the kit. If you assemble it properly, it tunes up very quickly and accurately. We'll see how it holds up later this summer when I use it for portable work!

I like it  Time owned: 0 to 3 months
Ive had mine for a few days. They have been around for a long time but I just got around to getting one.

I put her through the paces with my MFJ-9296 on 80M through 15M. I used a few different configurations of antenna and ran the rig at around 8 to 13 watts output (13.3V from a LiFePo gives me that output range over the 6 bands tested).
The EF Random wire was around 80 to 100 feet I think... truly random... Fed from a banana plug to bnc adapter directly on the T1. The rig and T1 were sitting on the ground and the wire went inverted vee at around 40 something feet. It found a 1:1 on all bands with a little loss on 80m but not much. I would retune until the swr went as low as possible. I was still putting out around 12 watts and made several qso's. A counterpoise made no discernable difference after trying a few different lengths...

Then I tested a 40 -10M Windom that was used in EF vertical and inverted L configurations (weird I know, but it works great when trees are limited). The short leg was set up as the counterpoise stretched out at 2 feet AGL, balun at feed point which was also 2 ft AGL, and fed with 25 ft of RG-174. Inverted L config had 35 ft or so vertical and the remaining 5 to 10 feet was horizontal. The T1 tuned to 1:1 on 80-15M with very little loss as well. I had a 6 inch RG-174 jumper from the MFJ-9296 into the T1 for all antennas.
I made two cross mode (cw to phone) qso's and several cw only contacts during my 1 hour test.

I'M IMPRESSED... I got tired of messing with the little, manual, kit tuners for my EF wire antennas, so I sprung for this T1 in pre-built version. I dont regret it at all. I guess I'm getting lazy.

I know a transmatch will always Introduce some loss based on match differences, but they did a good job with this tuner. Latching relays I believe...

I'm really happy. I purchased it specifically for my portable kit that runs between 3 and 15 watts depending on the supplied voltage. Git'r Done!!!!

Additional review  Time owned: more than 12 months
In my previous review I gave this thing a 0 and I'd like to slightly revise that. I borrowed a friends unit and that unit actually worked fine.
Just to comment HB9PJT: Nothing wrong with the antenna, I can tune it using an Icom AH-4 or a manual tuner. Indeed, the borrowed unit worked.

Very happy  Time owned: more than 12 months
I built my T1 more than a year ago. It wasn't the most complex of builds, but was rather a rather tight fit in it's compact case.

It's worked well since day 1. I've used on multiple SOTA activation's with some pretty ordinary antenna's.

I'm very happy and would spend the money to buy the kit again.

Superb  Time owned: 0 to 3 months
I have had the T1 for over a week and so far it has tuned everything I've connected from end fed random wires to doublets. I'm using it with a FT817ND and Anker Astro3 battery pack and it's small size make this an ideal combination for QRP operating. So far the W3EDP -,85ft wire + 17ft counterpoise is proving to be the best compromise ant but it's early days yet. Very happy ham!

Broke after 2 years  Time owned: more than 12 months
My assembled tuner was bought in 2009 and was lightly used with 817ND. It tuned fast and it worked nicely. I loved the tuner. In 2010, I ran into family issues and health problems. I stayed away from my radio activities for 2 years. When I tried to use my tuner in 2012, it just would not tune. The green light would flash and I would hear the chirp that the tuner made while tuning. Around the same time, I started to go blind due to diabetic retinopathy. After about a dozen surgeries in both my eyes, I am back to the point where I want to play with my radio again. So I tried to tune again, and of course the tuner still did not work. I tried a new antenna. Maybe the antenna is bad, I thought. But no luck. I contacted Elecraft, and they wanted $99.00 to fix the tuner + shipping charges both ways. I went ahead and ordered another T1(assembled) and I am hoping to be luckier this time.

Very good Tuner  Time owned: more than 12 months
This tuner is very fine. It has a good tuning range and tunes very reliable. It is supersmall. A jewel of electronic device. Battery consumption is very low. I can't remember when I changed the battery last time.

The last reviewer SM0RWO seems to me not to be an experienced ham because he knocks a very good product for a defect in his antenna wiring or antenna or maybe his T1 is not ok.

Matches Just About Anything  Time owned: 6 to 12 months
I use the Elecraft T1 with my portable QRP set up. It's small, light and I haven't come across anything that it won't match. I was leary, at first, about laying out the money for this thing but now I'm glad I did.

Excellent kit  Time owned: 0 to 3 months
This is an excellent ATU and very good as a kit. Anyone contemplating buying the kit, should be good at reading and following directions. Failing that you need to be good at desoldering. I fall into the later category. The direction are very good but must be followed exactly. I had to go back and rewind the sampler transformer cores. You can buy the transformers/inductors factory assembled from Elecraft, but with a little care and reading the directions they can be successfully hand wound.

Either factory or home assembled the end result is very good little ATU and should be suitable for QRP or mobile use.
