Hi,

I need some toroidal cores(powdered iron or ferrite) for general HF
use. So i guess i will be looking for cores in 3-30~ MHz range. I have
access to Philips toroidal cores in where i live and i need your advice
to find the suitable one. Waiting for your answers...

Thanks...

Suitable for WHAT? You say you "need" them, but what exactly causes
that need? What are you trying to accomplish?

Cheers,
