Re: [Elecraft] K3: birdie on 50.045?

I have found the 50.046.96 birdie on my K3 #732. In CW mode it does disappear when I switch the preamp off. However, in USB the tone is there with the preamp on or off. In only have the stock 2.7 KHz filter. Russ, N3CO - Original Message - From: "Dr. Werner Furlan" <[EMAIL PROTECTED
