SVG is extremely available, and extremely useful because it
allows you to scale the picture to any size you like, and retain
all of the detail. It provides a lot more functionality than just
that, but I am sure that you can use

The video is 1/2 hour. I thought it was good. He's a colorful speaker.
Anybody know how they made gears back then? Or machinery in general? What
did they use for a file?
yes for transmitter antennas, but not for receiver antennas in Austria

long as he want, but the height is limited similarly as in the US

Hal,
Gear wheels have been cut by hand for many a century. A simple dividing
head made from wood and fixed to a mandrel would index a blank wheel and
allow the teeth to be cut by a saw and then rounded up to a cycloidal
shape with a file. As time progressed shaped files were used and later
Good question. I intrigued me so I researched it. To make gears the Greek
craftsmen made a circular blank, then marked it out for the correct number
of teeth, probably using dividers, then filed the teeth with a triangular
needle file Analysis of the Antikythera Mechanism shows the sort of
Yes, flexibility is the key. Once upon a time I could hack hardware and

On most of these “buried” systems, the *intended* output is an audio ( 15 KHz)
signal. Since the carrier is below the bottom end of the regulations, you are
in “who

The problem comes from the fact that they modulate the carrier in ways the

Yes, but in the case of the lawnmower fence, and the
invisible dog fence, the transmitter drives the fence
as an antenna.
In the US, the antenna size for free bands is seriously
limited. As an example, the so called Lowfer band at
136KHz is limited to antennas no larger than 15m in length.
In practice it seems to be hard to fight interference issues at lower
frequencies. A local 50,000 watt AM (medium wave) broadcaster, put up a FM
(VHF) transmitter several years ago. One of the reasons they gave for going
to FM were the interference issues on the AM band. I noticed the
