Amateur Radio (Ham Radio)
History: This class of radio service was created to encourage experimentation with radios. The number of aspects of this hobby have grown to include, “purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication.”
Availability: Not as common as FRS radios and can be much more expensive. Radios are available at local/online radio shops, ham club events, and at Amazon/EBay.
License Needed: Yes. Free for 10 year license. $15 for test administrative fee.
Use: Personal Only. Cannot be used for any pecuniary interest (this is one of the test questions!)
Range: VHF/UHF handhelds 2-4 miles, mobiles 4-10 miles, repeaters 50-70 miles; HF radios signals can travel around the world
Equipment needed: Can build or buy any radio that transmits on amateur frequencies in your ITU region. This falls in FCC Part 97 Regulations.
Antenna: Detached. Can be a small Handheld Radio antenna to a wire antenna bigger than a football field.
Output: Up to 1500 Watts. But practice dictates that you use the lowest power you need to reach your contact.
Modulation: Any. You are encouraged to experiment and even create new forms of modulation.
Frequencies: Amateur frequencies allowed in your world region. The United States is in ITU Region 2 with multiple frequency bands. (Printable Version)
