HF — CW & SSB

The original long-distance mode. No repeater, no internet, no cell tower — just a radio, an antenna, and the ionosphere carrying your signal across the state, the country, or the world.

High Frequency (HF) operating is what most people picture when they think of ham radio: a voice or a string of Morse code bouncing off the ionosphere and landing hundreds or thousands of miles away. It's the original wide-area communications technology, and it still works when every other network is down — no towers, no satellites, no internet required.

SSB — Single Sideband Voice

SSB is voice communication on the HF bands. It's the most accessible way to get on HF: point a radio at a clear frequency, key up, and talk. Band conditions change by time of day, season, and solar activity, so part of the fun is learning to read the bands and find where the openings are.

CW — Morse Code

CW is one of the oldest modes in the hobby and still one of the most effective. A CW signal takes up very little bandwidth and can punch through noise and weak-signal conditions that would bury a voice signal completely, which is why it remains a favorite for emergency and long-distance work. Many operators find copying and sending code by ear a rewarding skill in its own right — and it's a great link back to the roots of the hobby, the same code spelled out in our club's own callsign.

Getting on HF

A Technician license gives you limited HF privileges (mostly CW, plus some voice on 10 meters). A General class license opens up the vast majority of the HF bands and is the natural next step for anyone who catches the HF bug. Our club can help you study for the upgrade — stop by a meeting and ask.

Field Day

Every June, we put HF stations on the air from the field for ARRL Field Day — a great low-pressure way to see CW and SSB operating in action.
