Thanks Don - I will do that. I am using the K1 without the tuner now, to see what happens for a while. Another list member reminded me to change the power meter jumper on the RF board. That took care of the power request and display problems. Now to find the 20 and 15 M power out problem. I am having trouble with the problem being in the tuner as I don't see any band specific circuitry there. I had assumed the problem would have to be in the high freq. half of the filter board. Being intermittent greatly increases the difficulty in troubleshooting. Banging the K1 on the table has no effect. Neither does course language. 73 Rick K7MW ----- Original Message ----- From: "Don Wilhelm" <[EMAIL PROTECTED]> To: "Rick Dettinger" <[EMAIL PROTECTED]>; <elecraft@mailman.qth.net> Sent: Sunday, April 23, 2006 5:21 PM Subject: RE: [Elecraft] Need help for sick K1
