Well,
thanks for all this, but the place where I live it is very difficult to find such things still, I'll try that, I was wondering if it will be better if I try first with AM, just for switching purpose, I'm thinking of making this (see the attachment )
Will this work ?, How far 100k carrier can go ? I just want to switch something in the next room (even the same room will do), BTW : Can any one provide a link that shows the calculation (derivation) of RC phase shift network's attenuation to be 1/29.
Why don't you ask in any radio club near you? At least to know what are the bands where, without license, you could experiment?
I would point you towards getting your hands on a copy of the latest A.R.R.L handbook and start reading...
It might already be in your local library, if not ask them to get it for you...
