A Brief History of Ham Radio
Radio communication has
been around since the late 1800s when Heinrich Hertz provided evidence for the
existence of electromagnetic waves. This was picked up by Italian electrical
engineer and inventor Guglielmo Macroni who helped spawn a revolution in
telecommunications that allowed long-distance messages to be instantly sent and
received wirelessly. These innovations provided the foundation for what would
become the cherished hobby known as American Ham. “Ham” radio, as it’s called,
involves the use of amateur radios to communicate for entertainment purposes,
rather than for advertising or broadcasting.
There is a designated
frequency range reserved for amateur radio enthusiasts between 3 kHz to 300 GHz.
There are no restrictions or regulations governing the purchasing of amateur
radio equipment or the use of ham radios for listening purposes. However, in
order to transmit on ham radios, an FCC license must be obtained. This differs
from CB radios, in that CB radios do not require a license, have limited
channels and can only broadcast in the 11-meter band (27 MHz). American Ham
enthusiasts have literally thousands of frequencies from which to choose
ranging from 160 meters and beyond. Amateur radio operators also have AM
(Amplitude Modulation), FM (Frequency Modulation), CW (Continuous Wave) and
various other analog and digital outlets from which to choose.
Once radio
communications took off, there was an explosion of transmitters and antennas
set up to create a robust communications network allowing for the transmission
of ham radio messages across the country and around the world. This created
rampant interference with military and other radio systems. This caused the
United States government to create the Radio Act of 1912, which mandated that
radio frequencies and stations be regulated. With the designation of the
various radio bands on the electromagnetic spectrum, radio broadcasting has
become organized and efficient while still providing plenty of freedom and
enjoyment.
Today’s American Ham
enthusiasts enjoy a radio communications network so advanced, Hertz and Macroni
would likely not recognize it. The features and functionality inherent in
today’s ham radios far surpasses the knowledge and abilities of American Ham
founders with innovations and breakthroughs arising each day. Thanks to
technological advances and increasingly affordable prices, there has never been
a better time to get involved with ham radio communications. Working with ham
radios is fun, educational and keeps alive a valuable, cherished practice that
dates back over 100 years. With everything American Ham radios have to offer,
what are you waiting for?
