Mike, Your problem is most likely the front panel connectors. This is a known problem for early K3s. Early K3s had tin connectors between the front panel and RF board. Elecraft switched to gold connectors around serial #4000. I just had my serial #3505 in for upgrades and they switched the connectors while they had it. You can contact Elecraft and they will send you the gold connectors for you to switch out yourself or send the radio back to Elecraft and they will change them for you if you are uncomfortable doing it yourself.

I have noticed recently that occasionally when I hit the band up switch the mode changes but the band doesn't. Seems to be getting more frequent. Is this a common problem and is there a fix?
