A Comprehensive Guide to Ham Radios: Licensing, Uses, and Experiments

Ham radios, also known as amateur radios, have been a fascinating and essential tool for communication, particularly in remote or disaster-prone areas. If you're curious about owning a ham radio, this guide will help you understand the procedure, the cool things you can do, and the complete details about these versatile devices.

About Ham Radios

Ham radios are used for personal, non-commercial, and technical purposes. They are particularly useful in areas with limited or no telephone lines or cell service. I got into ham radio a few years ago when I lived in a sparsely populated mountain community in Colorado, USA, where there was no way to call 911 in an emergency without driving 45 minutes to the nearest area with cell service. A local ham radio repeater on a mountaintop provided a more reliable solution.

The Procedure of Obtaining a Ham Radio License

In the USA, obtaining a ham radio license from the FCC requires passing a written exam. Here are the steps:

Exam Costs: The exam costs about $15, plus a fee for the testing organization for the venue and time. Offline Testing: You must take the exam in person and present a government-issued photo ID. Exam Content: The exam covers rules and regulations, some simple math about frequency and wavelength, and how to design antennas for different frequencies and repeaters.

There are three license classes:

Tech (Technician) Class: Allows operation in FM only on UHF, VHF, and 6 meters. These frequencies have a short range but offer many local repeaters to extend your range. General Class: Opens up more frequencies and AM operation, requiring basic Morse code proficiency. Extra Class: Offers the most frequencies and AM operation, without any Morse code requirement.

I am Technician class, and there is plenty enough for me to experiment with!

Uses of Ham Radios

Internet Interfacing

HAM radio enthusiasts have access to various online services like EchoLink, which interfaces ham radio with the internet. This service allows you to talk to anyone in the world via internet rebroadcast.

Emergency Communication

HAM radio repeaters can be used to call 911 during emergencies, providing a way to communicate when other methods fail.

Automated Packet Reporting System (APRS)

APRS is a system that can post your transmitted GPS location and other data to an online map. It also allows you to transmit output data from your weather station and view the weather from anywhere in the world. This is particularly useful for those with off-grid homes where wifi is not always available.

Contacting the International Space Station (ISS)

Ham radio enthusiasts have attempted to contact the ISS, which has a full ham radio station on board. Although it is not always possible, many hams enjoy the challenge and the novelty of it.

Long-Distance Communication

Transmitting "CQ" (meaning "anyone who can hear me please answer") is a common practice among more advanced hams who talk over long distances on lower frequencies and higher power. This activity also allows them to receive "QSL" postcards from all over the world, which are used as proof of their communication.

Important Reminders

Never transmit illegally on the ham frequencies! You are subject to fines and the seizure of your equipment. The FCC doesn’t actively patrol for this, but local ham radio operators take pride in patrolling and reporting illegal transmissions. Many reputable ham radio shops won't sell you a radio unless you have an FCC license or at least make you sign a waiver saying you haven't taken the exam yet.

Getting Started

A handheld HT (hand-held transceiver) with a 5-Watt transmission power can be purchased for under $100 after obtaining your license. I have a mobile unit at my house set up as a base station, which doesn't travel. I paid about $150 for the radio, $100 for the 3-band antenna, and about $50 for cabling. I also use an SWR meter to tune my antenna.

The essential equipment is usually tucked away in a corner of a bedroom. All you can see is the antenna on the roof and a radio front plate, microphone, and speaker in the living room.

Ham radio operators are generally friendly and helpful, with a public service state of mind. They are proud that they took the time to study for and pass the exam.

Have fun with ham radio after you get your license!
