A while back I asked about the outputting of wireless data on antennas. Now I understand how the data is transmitted, but how exactly do the receivers work? Also, could I make a simple device very cheaply for sending 1 bit of data ~1 ft. without buying a pre-made transmitter/receiver package? the response needn't be that fast.

Are you asking permission? If so, it's granted. Let us know how it goes.

No! I want to know HOW I could make one. All I need to do is send 1 bit of data about 1ft.

Breakdown voltage of dry air is about 30kV per cm, so around a million volts should do it.

That's not a radio. I was thinking something like this:

But I was wondering if I could easily build something like that myself.

But all the comments say that it generates excessive noise.

No, it says you have to keep the link busy so that the AGC doesn't bring up the noise.

But If I want to when a button is pressed to the receiver, how would I keep the link busy when the button is not pressed?
