EXTRA DON'TS
Don't think you have an up-to-date transmitting station unless you are using C.W.
Don't use a wire from your lightning switch down to the outside ground that is smaller than No. 4.
Don't try to operate your spark coil with 110-volt direct lighting current without connecting in a rheostat.
Don't try to operate your spark coil with 110-volt alternating lighting current without connecting in an electrolytic interrupter.
Don't try to operate an alternating current power transformer with 110-volt direct current without connecting in an electrolytic interruptor.
Don't--no never--connect one side of the spark gap to the aerial wire and the other side of the spark gap to the ground. The Government won't have it--that's all.
Don't try to tune your transmitter to send out waves of given length by guesswork. Use a wavemeter.
Don't use hard fiber for panels. It is a very poor insulator where high frequency currents are used.
Don't think you are the only one who doesn't know all about wireless. Wireless is a very complex art and there are many things that those experienced have still to learn.
