Perfect, thank you.
I got the spool of red baby hair today, and tried to wind the coil with teflon tape. The stuff is really hard to work with, and once you lay down a turn, it sinks in and won't move again. Once again, I ended up with some tiny gaps and maybe one overlap that I couldn't fix. I soldered it in, and it seemed to sort of work, I got a station at 560kc, but I had to leave shortly after. Came back, and it's the exact same thing. Stops working at 1100 or so.
I was hoping to be celebrating with Greg tonight Oh well. Next plan, redo it again with the polyethylene plastic to insure there are no irregularities whatsoever, and maybe add a turn or two.
Edit - I got it to oscillate. I pulled the 42 audio tube to try to see what is causing the 'thunder' noise, when I put it back in it worked fine across the dial... Heard Atlanta, New York, Chicago and Nashville. It worked for 5 mins or so, then died again. What a terrible headache of a radio. At least I know that coil seems to be responsible, it didn't do this before.
