The Elecraft T1 is a stand-alone, miniature antenna tuner unit specially designed for use with low-power HF/6m transceivers. Despite its small size, it uses a built in 9V battery, provides a wide matching range and can handle powers up to 20 watts SSB/CW or 10 watts in FM/AM/digi. It is a very cool general-purpose ATU for mobile and portable use. The T1 is available either ready built or as a kit.

Tonight I have tried to use the FT-817 remote cable that I bought together with the T1. First, I wanted to find the leaked RF info signals sent by the T1. According to the manual, there should be at least one signal on every ham band and I found one around 7024 kHz.

I have now done som basic tests of the T1. I decided to tune the MP-1 to somewhere in the 40 meter band and then try to match it with the T1 on the other bands. The initial setting of the MP1 was as follows:

I have just completed the assembly of the T1. The power on tests from the assembly manual are all all right. I must wait with the functional tests till I am back in LMX, because I have no 50 ohm calbes here.

I have now finished the control board as well. All resistance checks passed. I can not do the LED test, because I do not have the diode tester here, it's in LMX. In any case, I have been very careful when mounting the LEDs, so they should be all right.
