T hey were first used around 1888 and remained legal until the 1920s when their use became greatly restricted. World War II delayed their complete ban outside of emergency communications for a few years. Now the only way to use them legally is inside a faraday cage. They operate as jammers for the same reason they were banned, they take up a lot of the radio spectrum. A spark gap transmitter is fairly simple. Send a high voltage current through an air gap, when the resistance of the air breaks down a spark will cross the gap. When this happens electromagnetic radiation is emitted. You can test this in your house fairly easily. Turn on some speakers so they are powered but nothing is coming out of them. Computer speakers that are on will work as will a stereo set to CD or tape with no CD or tape playing. Flip your room lights on and off in rapid succession, you should hear a clicking from the speakers. The clicking is RF energy that is being picked up from the light switch. |

I have in front of me as I type a copy of Fundamentals of Radio for those preparing for war service. Published by The American Technical Society 1944 edition. It's got a whole section on different types of radio jamming. |

Quoting: Judethz That's cool! Maybe if there were easier ways you know of, you can make a thread and share them? I used to be a Radio Teletyle Communicator for the Pershing II missile and we had to encrypt and decrypt radio waves from enemy receiving our information. That's why I thought this was cool information. |
