What makes me think GM is in his element with this old technology ? 

No offence Mike, I'm one of your biggest fans really.

Crystal sets were old technology when I was a lad.   :)

I used to sell crystal sets to people when I was at school. That is where I came up with the ferrite rod tuning method, it was a cost down on the variable capacitor. I made the boxes out of cardboard and used to sell then for three and six ( 3/6 ) and it cost me about two shillings to make. Not sure what that is in new money.

When nobody else is listening preferably... my landlady just gave me a O___o look as though I'm an escaped mental patient ;)
