[CW] Spark

Thu, 4 Sep 2003 00:02:46 -0400

Dear CW Reflector,

Our Canadian brothers are rightly proud of the part their country played in
international communications and the birth of trans-Atlantic wireless
communications.

There are several sites on the web giving some information of VE3BBN's
transmission on 80 meters with a spark transmitter - including a recording
made at 150 miles distant (at the first mentioned page).

Here is some of the information from the web:

>From the page:  http://www.qsl.net/g4rfr/marconi.htm

Spark Gap Transmitter Signals for Marconi Centennial
12 December 1901 to 12 December 2001

 Spark gap transmitter signals in today's radio spectrum could be considered
analogous to horse and buggies on our motorways, but during commute rush
hour they may actually out perform rival cars with their impatient drivers.
There are legal equivalents as well. However, exceptions for the banned
Spark Gap Transmitter apparently are being made for the Marconi Centennial
where under controlled conditions they may be used. One such transmitter has
been constructed, tested by David Wilson VE3BBN and given the green light in
Canada. The background sound is a test signal heard and recorded by Dave
VA3ORB 150 miles away on

And here:

Final Report - Operation "Marconi 100"
http://www.qsl.net/ve3bdb/marconi100.html

>From that page:

[A] low-powered, rotary spark-gap transmitter that had been designed,
constructed and operated by David Wilson (VE3BBN) of St David's, Ontario.
Operation of this transmitter had been approved by Industry Canada for a one
hour period during the evening of 12 Dec '[20]01. This was limited to
broadcasting the words "MARCONI S". Two-way communications using the spark
transmitter were not attempted during this demonstration.
