T1 no longer tunes.

[Elecraft mailing list]

Hello,

My T1 doesn't tune anymore. I built it only a few weeks ago. It used to
work just fine. Now the tuner no longer goes through the relays clicking
routine and only shows SWR with the LEDs.
Any suggestions? Thanks guys!

Hi Gil,

Make sure you have not accidentally put it in bypass mode. That is the most common mistake made on the T1.

Well, it looks like the bypass button is no longer working. Neither
tapping or holding the button does anything...

It also will not tune if the radio is not sending out an RF.

Have you turned down your RF output to Zero?

Failing that, try resetting.

If that doesn't work, if you don't get any RF out with or without the tuner
in line, then either the finals have failed or you have a RF lead that has
failed internally between the RF board and the tuner.

I would also open it up and have a look to see if everything is firmly
connected.

Is your output power to low?
I built a T1 a few weeks ago and at first it worked good, Then it started acting up... 
I had turned my output power down, turning it back up solved the problem.

Note: As per the manual 2-5 watts is the recommended power setting.
