Technician Class Frequency Privileges in Ham Radio

When you’re getting started, remembering where you’re allowed to operate is important. As a Technician licensee, you have free access to all amateur frequencies above 50 MHz, but what about on the shortwave high-frequency (HF) bands? This chart helps you follow the rules. A band-by-band plan showing where to find different types of activity is available from the American Radio Relay League (ARRL).

Band Frequencies (In MHz) Modes You Can Use
80 meters 3.525 – 3.600 CW
40 meters 7.025 – 7.125 CW
15 meters 21.025 – 21.200 CW
10 meters 28.000 – 28.300

28.300 – 28.500

CW, RTTY/data, 200 watts PEP maximum power

CW, phone, 200 watts PEP maximum power

Above 50 MHz All amateur privileges

CW = Morse code; PEP = peak envelope power; RTTY = radioteletype.

General Class Frequency Privileges in Ham Radio

Soon, if you haven’t done so already, you’ll be thinking about upgrading. You have many more frequencies to use on the high-frequency (HF) bands, as shown in the following table. A complete chart of the U.S. frequency and mode privileges for all license classes is available from the American Radio Relay League (ARRL).

Band Frequencies (in MHz) Mode
160, 60, 30 meters All amateur privileges
80 meters 3.525–3.600 CW, RTTY, data
