Powdered Iron Slug Source for 27MHz Circuit

(1/2) > >>

fuzzoli:
Does anyone know where I could find a source of threaded powdered iron slugs for a simple 27MHz transmitter circuit?  The dimensions are:

   3/16" Dia. x 5/16" Long (for the crystal controlled oscillator)
   1/4" Dia. x 1/2" Long (for antenna matching)

I'm in a cloning mode...more details of the project to come as I take more pictures.

Thanks!

At 27 MHz, it's certainly not powdered iron, but ferrite.

Apart from that, you need a better camera :)

That looks like a picture of a page in a 1970s ARRL handbook.

slug inductors come with those kinds of cores in them. They can be removed. They must be standardized.

Conrad Hoffman:
You can find them surplus-

The best bet is usually buying complete coil forms with slugs. I also find them at hamfests and such, though there may not be any hamfests for a while.
