[Elecraft] K1 Band Display Problem

[Mike WA8BXN]

It sounds to me like a menu setting for band 3 and not a hardware problem.

K1, SN 1976 with 1.09E firmware, 4 band module and ATU. It's been 

working flawlessly since I built it around 2005 or so. 

 

It works fine on receive and transmit on all bands except that when 

changing bands it displays 7, 10, 10, 21. Though indicating 10 mhz, it 

works fine on 14 mhz, but the display is obviously wrong. Probably a 

solder joint that decided not to work, but the LCD and added backlight 

obscure pins on the firmware socket. I've resoldered pins on the LCD and 

the firmware socket that I can reach. I've also removed the firmware 

chip and reseated it. Problem surfaced suddenly on a camping trip a 

couple weeks ago. 

 

Am I at least in the right area? If so, the next thing I'd do is try to 

desolder the LCD and touch up solder joints on the firmware socket.
