I also tried a 5m length of wire draped over a curtain rail, using the central heating system for a ground. The developers at Elecraft did really go a long way to take full advantage of 1t a microcontroller in this kit. The band is sent to the T1 as a number between 0 and 12 by encoding the four bits and sending them via the tip of the connector. The most interesting question is, of course, what can the T1 tune and how fast?
I made two cross mode cw to phone qso’s and several cw only contacts during my 1 hour test.

Moment of truth The T1 is controlled through two push-buttons on the top panel, and gives you information through three LEDs. Elecract T1 always tries to find the best SWR and does not stop at 1.
I was still putting out around 12 watts and made several qso’s. 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. I will post the files on Thingiverse shortly. You’ll see the SWR displayed and hear the relays clicking through different combinations to find the best match the manual claims there are 32, possible combinations.
I have the same setup, and I just send a string of dits. Technical Description The T1 uses 7 inductors and 7 capacitors in an L-network. All SMD components are already installed when you receive the kit.
Hope to make my first SOTA this weekend!

Then I tested a 40 M Windom that was used in EF vertical and inverted L configurations weird I know, but it works great when trees are limited. 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. One should keep in mind that the T1 is intended to be a portable or mobile equipment.
It is really important to not loosen the simple nut directly at the T1 enclosure, because you will have to open the enclosure to tighten it again. I found this to be very, very close to the maximum number of turns there is room for on a T One of the things about Elecraft products is the enthusiastic customer base and the company’s responsiveness to criticisms and suggestions for improvements.
Automatictuner Elecraft T1 ready built
There were very minor circuit changes between the first and second edition 2Bs, nothing of any significance. I built mine from a kit a couple of months ago, and use it with my Elecrraft X1M Platinum.
I dont regret it at all. InI ran into family issues and health problems.
Latching relays I believe Using band data via remote control can, however, reduce this time by eliminating some L elwcraft C values based on the operating band. If you assemble it properly, it tunes up very quickly and accurately. Elecraft recommends that a power of 2 to 5 watts is used for tuning, but the T1 will tune using as little as half a watt. When the band changes, it turns on the T1 and sends it band information, allowing the antenna to be automatically tuned to the new band.
The same goes for power reading. Elecraft T1 Tuner failing to tune Equipment. The green light would flash and I would hear the chirp that the tuner made while tuning. Radio amateur and SDR hacker during the night.
The T1 is the first Elecraft product that is available both wlecraft and as a kit. Each inductor and capacitor has its own DPDT relay, with the individual sections of each relay placed in parallel for reliability.
The assembly manual is very detailed. To give elecrzft an idea of how small thing are look at this picture:. Otherwise the control board may not fit onto the main board without scraching the MCU.
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 caused by the extreme mismatch conditions encountered using certain tuning combinations. The space is even tighter here than on the main board and one must pay special attention not to make any mistakes. The idea was to be able to position the tuner directly at the feedpoint and have the feedpoint 2 – 3 feet above ground level. It’s also worth bearing in mind that, because it uses the FT’s CAT port, you can’t use this adapter and connect the radio to a computer at the same time.
Had the top off my old MTR-5B tonight as I thought it might benefit from a back up battery change before g1 winter bonus activation period really kicks off.
I prefer big control panels with big, easily reachable, one-function buttons and knobs and I hate multi-function, multi-purpose, multi-level submenus. Fed from a banana plug to bnc adapter directly on the T1.
I have had the E,ecraft for over a week and so far it has tuned everything I’ve connected from end fed random wires to doublets. It can be used with any 0. They have been around for a long time but I just got around to getting one.
I built this as a daughter board that the Arduino Nano can plug into.
