Re: [Elecraft] T-1 tuner stopped tuning
Re: " I have excactly (sic) the same problem with the big MFJ-927 tuner and the preprogrammed chip replacement from the company made no cure" No, wait, what??? You have the same problem with a tuner make by a different manufacturer? It is time to start looking for items that are in your system no matter which tuner or antenna you are using. Don't ignore the radio side of the tuner. An intermittent short or open in a connector or coax on the INPUT side of the tuner will cause the tuner to be unable to figure out what frequency you are on since it can generate square waves with harmonics well above HF. Look for items that are common no matter which tuner you are using, and don't forget the radio itself.

Re: [Elecraft] T-1 tuner stopped tuning
Don, Jim, thanks. Could be a processor, agree. Paradoxically, I have excactly the same problem with the big MFJ-927 tuner and the preprogrammed chip replacement from the company made no cure, :). The buttons seems like working for they do switching during the test mode. I'll definetely write to the Electaft tech support, they are quick and friendly, once have helped me a lot by guiding through the fix of the K3 I/O board.

[Elecraft] T-1 tuner stopped tuning
Hello, My Elecrat T-1 mini-autotuner stopped working after some 10 years of flawless service... It started behaving erratically , it either does not react to the RF input , or if it does then never finds the tune ending up with the red LED on. It is not related with the antenna type, it is all the same even with the perfectly tuned R-8 on. The self LC test procedure as described in the manual , though went ok. Disconnecting and re-connecting the battery doesn' help. I also tried to eject and reinstal the microprocessor chip to no avail.

[Elecraft] T-1 tuner in kit form
Hello all group members merry xmas and happy new year to all I will be shortly building the T-1 atu kit and would be gratefull to know if there are any build tips that i should look out for that are not covered in the instructions. Also my aim is to use the T-1 on 20/15/10m with my K2 and was wondering what antenna's have worked for others on these bands 80/40m are not going to be used at the moment and I only have 35ft of space to play with,also i have a elecraft balun built as 4-1 and i notice it has a earth terminal does this mean i can use it with a long wire if so what side do i connect the main wire to or does it not matter,i was thinking of a half wave wire 33.42ft on 20m with a quarterwave counterpoise this should also work on 10m but it is 15m that i am not sure about. Thanks the kit should arrive in the uk next week. Mick M1MGD K2 #4785K1 #1532 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] T-1 Tuner
I went to the suggested website and looked at the pictures. However, there is no more information about this tuner. Can anyone tell us when the T-1 will be available and what the price is expected to be?
