This is KB1JOY. Welcome back for another installment of our Throwback Thursday blog!

As part of our National Electrical Safety Month coverage, the NFPA Research Library & Archives thought we would share a piece from the archives relating to Amateur Radio and introduce some of our readers to a popular hobby at the same time.

Amateur Radio enjoys a long and rich history. Over the years, Amateur Radio enthusiasts (or Hams) have made a number of significant contributions to their local communities and to the sciences. Today Amateur Radio (ham radio) is still a popular hobby that allows people to experiment with electronics and communications in a fun way.

“Although Amateur Radio operators get involved for many reasons, they all have in common a basic knowledge of radio technology and operating principles, and pass an examination for the FCC license to operate on radio frequencies known as the “Amateur Bands.” These bands are frequencies allocated by the Federal Communications Commission (FCC) for use by ham radio operators.”

We hope you enjoy the following story and image!

From The NFPA Quarterly v.16, no.2, 1922:

The radio signaling apparatus in the home of Mr. Hiram Percy Maxim, Hartford, Conn. Mr. Maxim is president of the American Radio Relay League. Most amateur experimenters locate their station in their home, and inasmuch as they are unable to change the surroundings they must, to a certain extent at least, take things as they are. A careful study of the conditions will, however, often enable one to overcome and seeming handicap which may exist. This is just what Mr. Maxim has done. As a result, he has an efficient equipment without some of the unfortunate hazards which surround other amateur stations. Mr. Maxim made frequent grounds inside and outside of his home. He made at least twenty driven pipe grounds, running the ground conductor from the pipes to a water pipe outside of the foundation wall. Inside of the house, Mr. Maxim connected, electrically, all soil, gas, heating and other metal conductors by means of a copper bonding wire, and connecting this bonding wire to a water pipe, thus providing means for “draining” any static accumulation within his home.
