73-Mix Ferrite

This is a BN73-302 Binocular Ferrite Core.

73 mix ferrite is suitable for applications in broad band transformers up to around 10MHz.

Exactly what I need for my forthcoming (if I ever get time) ground loop antenna experiment.

Another in a long line of geeky blips taken of things I find lying around at the end of the day after being far too busy with work!
