The ARRL Spectrum Defense Fund supports ARRL advocacy efforts in official Washington and worldwide to protect and enhance Amateur Radio frequencies.

Thanks to the support of ARRL members, ARRL has maintained constant vigilance and taken decisive action throughout the years, including:

Defeating the threat that Little Leo satellites posed to the 2-meter and 70-cm bands.

Removing high-powered international broadcasting stations from the heart of the 40-meter band - doubling the size of the worldwide band and making it more useful than it had been in 70 years.

Working with out colleagues in the International Amateur Radio Union to gain global allocations at 135 kHz and 472 kHz (domestic implementation is the next step)

Battling the Broadband Over PowerLine (BPL) interference for six years including successfully challenging the FCC in court on its prejudice that tainted the rulemaking process.

Defending microwave allocations against the onslaught of commercial wireless broadband.

Seeking an international allocation at 60 meters (5mHz).

Your contribution to the Spectrum Defense Fund ensures that ARRL will have the resources to meet future challenges when they appear and to protect your operating privileges.
