What is Freeband?
“Freeband” refers to the spectrum immediately outside the legal 40-channel CB allocation (roughly 25–28 MHz excluding the authorised CB channels). Enthusiasts have long used modified CB or export radios here for long-distance (DX) contacts via ionospheric skip, mainly on SSB.
History
From the 1970s onward, operators frustrated by crowded legal CB channels or seeking longer range began modifying radios to reach frequencies just outside the band. A global freeband DX culture developed, with calling frequencies and informal networks. Enforcement has varied by country and era; many freeband operators eventually obtained amateur licences and moved to the legal 10-metre band.
Reality Today
- Some activity still exists, especially during solar peaks
- Legal alternative: get a ham licence and use 28 MHz (10 m) properly
- Modern export radios often include freeband coverage — that does not make transmitting legal
