I should have proof read this first. That is the source voltage on Q19 that is off. Chuck ___ No banners. No pop-ups. No kidding. Make My Way your home on the Web - http://www.myway.com ___ Elecraft ma

Chuck, You are on the right track, but I don't believe you can conclude that Q19 itself is at fault. The higher voltage you find at the source is caused by Q19 conducting more than it normally does, and that indicates the gate bias is running too high - this JFET (like many other oscillators) use

Greeting to the List, This is my first post. I'm building K2 sn5939 and have hit a snag at alignment and test part II. It actually went through all of the tests and alignment OK, but when I hooked an antenna up to try the receiver I notices some unusual symptoms. To cut to the chase, what
