Hi ULF,

I've ordered some components to build a mains transformer (actually just a coil) for further 970 Hz experiments. It has an EI core, to allow adding an air gap to align the inductivity!

It is very nice, the quality is very good and it is not so expensive. Worth to play with.

The idea is to build a few identical coils for 970 Hz (magnetically isolated to each other) which allow to run more voltage and antenna current down on 970 Hz...

73, Stefan
