Re: [Elecraft] T1 not tuning

[William Hammond via Elecraft]

Hi Fred, when you operate bypass do you hear a relay click (K8)?  If so the MCU 
is working and you eliminate a good bit of circuitry,

Have you read this?  There is a schematic on page 12.

I changed the battery out and still the same issue from 6-80m. Tuner just stays 
on yellow light. Have tried bypass off and on and still seems like same results.

Re: [Elecraft] T1 not tuning

[Paul Jewell]

Not sure if you are referring to my post from a few weeks back. When I finally 
spent time diagnosing my problem, I can confirm it is doing everything as 
expected, except it continually flashes 4 yellow. Based on a very helpful email 
from Elecraft technical support, it is clear that something is keeping the 
on/off transistor energised. I haven’t yet had a chance to diagnose further 
(due to work commitments). 

For your case, I recommend trying with a new battery before deciding it isn’t 
working. Then make sure it isn’t in bypass mode before tuning. If this doesn’t 
work, post more details about that happens when you try to tune.

Good luck!

Best regards,
Paul

[Elecraft] T1 not tuning

[Fred VE3FAL]

I had just read a post from someone who said their T1 had quit tuning. I pulled 
mine out of my qrp go-bag only to find mine has also stopped tuning. Now, with 
that being said. I have not changed the battery out for a new one as of yet. 
But wondering if the other person who had issues came to a resolve?
