A friend of mine is trying to build an oscillator that has
a frequency range is the terra cycles, that is well over one
trillion cycles per second.
But that will not be easy. We are currently looking for information
of what components that would be necessary to make such a device
or if such a device can be bought somewhere...
If anyone have information that can be of help, don't hesitate, but instead
let me know....
Thanks,
Lars
