Well, I got the audio transformer sooner than I thought, and have it in. It sounds very good, and I appreciate the suggestion Brenda. I had the same thought about the sqealing between stations on the upper bands being due to the audio problem, however it is still there. Of course the oscillation I was seeing in the audio section is now gone.
These birdies, or whatever you want to call them are not heard anywhere on the BC band. Now it's SW1 and SW2. I can tune in most SW stations and there is no heterodyne. I think have have something mixing with the osc, and the heterodynes are much stronger when I attach the antenna. It almost sounds like I'm listening on SSB as I tune up and down the band hitting carrier after carrier, until I find a strong station. I have moved wires around in the osc section thinking I've got one to close to something and causing the oscillation to start, but no luck. I'll keep looking.
Thanks Again
