Hello All LFers
I just thought that I would add my two pennyworth to the debate regarding 
RadCom 500kHz constructional articles. There must be many of us who design 
and build our own equipment, but do not submit it for possible publication 
because, state of the art technology it is not, the design is not 
particularly elegant, and the Technical Editor and the more accomplished 
contributors would fall over laughing when they saw it. But most of these 
projects are practical and they work. I work on the KISS (Keep It Simple 
Stupid) principle, don't use three components when one will work just as 
well. My 500kHz TX does not have any fancy CW sidetone circuit on transmit, 
just a piezo buzzer wired across the keyed 12v line to the driver board, the 
most complicated bit is the LCL output stage, which delivers 23W into a 
50ohm dummy load and 900mA up the antenna, the TX/RX switching is like the 
old days, a simple toggle switch.
On the subject of circuit symbols, for the Admiralty, resistors had to have 
a set number of points on the zig zag, wires crossed using bridges, and 
capacitors were called Jars.
I am now preparing to travel to China to view the Total Solar Eclipse on the 
1st of August, when I return I expect to find messages calling for me to be 
burnt at the stake for such heresy.
