On the other hand, because of the pocket-sized design of this device, there is very little space and one must also be very careful when soldering. Yaesu should have built something like this into the FT in the first place. I found this to be very, very close to the maximum number of turns there is room for on a T Email Subscription You are not subscribed to this review. Moment of truth The T1 is controlled through two push-buttons on the top panel, and gives you information through three LEDs.
Combining 7 inductors with 7 capacitors in 2 network types, the Electaft has a total of possiblities to try.
Elecraft T1 ATU – Amateur Radio Station M0OBU
The coarse phase takes the longest time because the impedance is an unknown. The green light would flash and I would hear the chirp that the tuner made while tuning. Elecraft cautions FT users against tuning using the full 5 watts, as the early FTs not the FTND model seem prone to blown finals, which might be elecarft by the extreme mismatch conditions encountered using certain tuning combinations.
It matched my small non-resonant attic loop, which has an SWR of more than To give you an idea of how small thing are look at this picture: It’s worked well since day 1.
The tip carries the data about the band, the ring is used to trigger a retune of the ATU and the sleeve is the ground. There’s only a small difference in price. Symptoms checked included the bypass feature, excessive RF, different antennas, leads, battery etc. It was an easy kit eleceaft build all components that need to be installed are through-hole, you just need to make sure elecrat leads are clipped off FLUSH with the board surface after soldering. The connection to the T1 is made using a 3.
Surely you can have it lying anywhere, but if you want to see the front panel and access the controls, you will have to make some sort of mount for it.
When that is done, the green LED begins to blink for 3 seconds and, if one begins to transmit during this time, the T1 will start to re-tune. Web Hosting by iPage.
The IF command contains the frequency that the radio is tuned to. The user must manually initiate a re-tune if required.

One should keep in mind that the T1 is intended to be a portable or mobile equipment. The elecraaft files are now online at On masts with a very smooth surface, it may be better to use rubber band without a textile coating so that the tuner does not slide down. About the size of a e,ecraft of playing cards, weighing next to nothing well, less than grams and powered by an internal PP3 battery, it’s the perfect companion for anyone who likes to take small, low-powered radios out into the country or up into the hills.
Using the Info feature one can obtain detailed information about the full state of the tuner and this includes which coils and capacitors are currently used. 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.
The kit shipped on the day Elecraft promised, and a fortnight later a man from ParcelForce was knocking on the door asking for money. I’m very happy and would spend the money to buy the kit again.
Having the T1 in the familly for some weeks now it is really difficult to say anything bad about it. I tried a y1 antenna. So detailed that even people with not much electronics experience can follow it at do it right in the first attempt. I think the circuitry ramps down the power too low? With only two buttons, operation is extremely simple: Elecdaft developers at Elecraft did really go a long way to take full advantage of having a microcontroller in this kit.
Elefraft T1 can also be turned eecraft using the external control flecraft, which can provide information about the band selected on the transceiver, allowing the T1 to automatically tune the antenna using the previously stored settings. I got tired of messing with the little, manual, kit tuners for my EF wire antennas, so I sprung for this Elecdaft in pre-built version. The most interesting question is, of course, what can the T1 tune and how fast?
The assembly of the main board took me approximately one and a half day including winding the coils. The adapter is a great boon, allowing you to switch from band to band without tempting you to send a burst of spectrum-polluting RF to re-tune the antenna. It’s only slightly bigger than a pack of playing cards.
I dont regret it at all. I made two cross mode cw to phone qso’s and several cw only contacts during my 1 hour elevraft. The T1 always tries to find the best SWR and does not stop at 1. Fed from a banana plug to bnc elecratf directly on the T1. This board contains the NPN elecrwft, a current limiting resistor and a three pin connector that is used to connect the cable that carries the signal to the T1.
I know a transmatch will always Introduce some loss based on match differences, but they did a good job with this tuner. It is very important to mount the parts in the same order as specified in the assembly guide, otherwise you may find yourself having a hard time. I have the same setup, and I just send a string of dits. One must keep in mind that this is a pocket size tuner and the space is really tight, so it is a little difficult to solder at many places.
I’m looking forward to putting this little tuner into elrcraft in the coming years. The first two versions were two band, the first one was board only, the second version included a steel and aluminum enclosure made by TenTec.

Hi all, last weekend, I tried several 3D-printable designs for a mount for my Elecraft T1 tuner so that one can directly attach it to a fishing pole or other antenna mast solution. It is, however, different with the T1. My 5W signal received good reports, suggesting that the power is being radiated by the antenna, not dissipated in the tuner. A jewel of electronic device. The second button is used in combination with the first to switch the tuner in-line or to bypass it, or if you press, hold, and release, it will give you detailed power and SWR information by blinking the yellow LED in slow Morse.
