All.

I read up on hertz in the book, and built one of his early experiments,
because he promises up to 2cm (1")long sparks in the receiver circuit.

The setup that I have dublicated is one, where there are 2 large copper
balls  3 meters (10`)apart. connected with 2 wires, each 1.5 meter long
(5`)and meeting in the midle in a spark gap made from 20mm balls(1").
the gap is 10mm long(3/8"). An induction coil is connected across the gap.

A receiver coil is made into a rectangle 1.2meter by 80cm (4`by 3`), and
with a sparkgap in the midle of one of the long legs. the gap is made
from a 12mm ball (1/2") and a piece of 1mm wire (18AWG). the receiver
coil is positioned 40cm from (1,5`), and parallel to the transmitting
antenna.

The gap in the receiver coil is 3mm long (1/8").
Mr. Hertz is accurate to the fact, end even the description of the sound
from the spark gap is informative, and has to be reproduced for results.

When the sparks dance in the transmitter antenna gap, there is corona in
the receiver coil gap.

The picture that I took does not offer justice to the real thing, but my
camera does not fare well in the dark.

This has been a fun and rewarding experiment, and I thank all who helped
me in setting it up.
