Default Re: Homebrew transmitter project (Frank vs. Oskar :) )

Gaah! Frank is allready way ahead of me!

It's looking really good Frank! I want one of those transformers too, have I mentioned how much I like heavy metal?

I'm still wondering how I should do with the RFCs' for the oscillator and final valves. I only have one proper, section wound, RFC. I was thinking of making my own coil form with sections, I bought a plastic rod for this. But how the heck does one do the math for such a thing? And winding it by hand?

I'll at least be winding the oscillator and 807 grid tuning coil myself. But those are easy.

For those who haven't seen it already, I'll link to my schematics:
