	Radicon, Radicon, Radicon!!  My keyboard was full of typos last night.
As for building devices in the past couple of years I've built several
different coherers and spark transmitters which worked and I seem to
remember that others here reported doing the same.  I also have a
Radicon Bus which works quite well for distances of thirty feet.
Receiver is a coherer which activates a meter-type sensitive relay and
transmitter is a small spark coil which runs from 3 D cells and has an
antenna about a foot high.
