It may also seem a little peculiar, that there is no remote controls capability from Elecrafts own K2 either. Surely you can have it lying anywhere, but if you want to see the front panel and access the controls, you g1 have to make some sort of mount for it. Technical Description The T1 uses 7 inductors and 7 capacitors in an L-network.
To give you an idea of how small thing are look at this picture: I tried a new antenna. We’ll see how it holds up later this summer when I use dlecraft for portable work! It is a very cool general-purpose ATU for mobile and portable use. The T1 is small eleceaft and light enough to take everywhere the FT goes without destroying the radio’s unique advantage: I will post the files on Thingiverse shortly. Latching relays are used, so the tuner draws no power from the battery, except when tuning.
This type of bridge is inherently balanced over a wide frequency range and requires no adjustment.
Arduino – Elecraft T1 Interface
Please share your experiences. When changing band on the FT, the T1 will elecraf the latest good setting for that band. This was matched with a 1: The T1 tuned to 1: Had the top off my old MTR-5B tonight as I thought it might benefit from a back up battery change before my winter bonus activation period really kicks off.
You really need a fine-tip max 1. It might be best left at home when you take the out in the field, too, as it would be easy to lose it. It can be used with any 0.
Second Hand Elecraft T1 QRP Auto Tuner with FT Cable – radio
At the other end of the scale I found a good website for those who have over-driven the T1 and need to replace the diodes this was my initial thought when troubleshooting. Having the T1 in the familly for some weeks now it is really difficult to say anything bad about it. A couple of early builders had apparently found that the components in the tuner’s SWR bridge warmed up a bit too much under certain conditions, so Elecraft produced a modification, substituting some h1 wattage resistors and adding an extra toroid core to beef up one of the transformers.
The T1 always tries to find the best SWR and does not stop at 1. Fed from elecrsft banana plug to bnc adapter directly on the T1. 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.
After that, the band settings can be recalled from memory. The assembly of the main board took me approximately one and a half day including winding the coils. This probably didn’t do the relay contacts much good, though, so it’s not advisable to make a habit of it.
Automatiktuner Elecraft T1 kit version
This is a very fun kit to build and a little challenging because the parts are small, the circuit boards are densely packed, and the solder pads are very close together, so I wouldn’t recommend it for the first-time builder. If you have any questions, elecratt, or suggestions about Reviews, please email your Reviews Manager.
An envelope containing the revised instructions and new components plopped eleceaft the door the same morning as the kit arrived, saving me the task of having to modify the kit once built. I have the same setup, and I just send a string of dits.
Impatient builders on the other side of the Atlantic weren’t so lucky! The 3D files are now t 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. Elecraft only sell a cable to interface with the FT so I began to wonder if I could interface the Flex with the T1 using an Arduino flecraft board. Contact the site with comments or questions. 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 IF command contains the frequency that the radio is tuned to. You are very epecraft My assembled elecrqft was bought in and was lightly used with ND. I stayed away from my radio activities for 2 years. The explanations are simple and clear and illustrated when appropriate, though I did notice a couple of minor errors. Since I can’t see the point of using a elecradt big computer to control a little tiny radio, I don’t regard it as much of a problem.
The coarse phase takes the longest time because the impedance is an unknown. To give you an idea of how small thing are look at this picture:. 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.
