Understanding ham radio frequencies
Just like most wireless technologies, ham radio works using electromagnetic radiation. With the right frequencies, you send Morse code, voices, and data around the world. The more you know about antennas, receivers, and transmitters, the more you can do.
Ham radio, like most radios, operate on the radio wave spectrum. The radio spectrum has huge wavelengths that can travel as far as 62 miles. Some experts even know how to use ham radios to bounce frequencies around the globe, as mentioned above.
Because radio frequencies are so versatile, the spectrum is divided into multiple bands. This ensures that certain frequencies are reserved for a specific technology.
Maritime radio communications often operate in very low rates. Meanwhile, extremely high frequencies, or EHF bands work best for satellite conversations.
Ham radio frequencies aren’t the same as the normal radio channels you’re used to when listening to commercial stations.
Frequencies for ham radio often sit on the very high radio and high radio frequency wavelengths. The VHF (extremely high frequency) environment provides an easy communication system for multiple ham radios.
Ham radio operators often take advantage of repeaters for VHF that radio clubs have located all around the country. Many of these repeaters even come with back-up power options, like solar power, making them ideal for keeping communications going in emergency circumstances.
Ultra-high frequency radio waves also play a part in ham radio. These frequencies range from 300Mhz to 3Ghz. UHF systems have much shorter wavelengths than VHF. However, you do get a higher bandwidth and audio signal quality.
Do you need a ham radio license?
If getting to grips with ham radio for beginners leaves you curious about being more involved, there are some extra steps to take. If you want to experiment with short or long-range ham radio, you need the right license.
