As explained on ARRL, US radio amateur emissions on our 60m channels must be precisely centered in the center frequency of each assigned channel, that is, 5332.0, 5348.0, 5358.5, 5373.0 or 5405.0 kHz. The five frequency channels that US amateur radio operators share on a secondary basis with US federal government users on 60 meters (5 MHz) pose unique requirements for CW and digital operators. Our decreasing solar activity and residential antenna restrictions have attracted increasing numbers of radio amateurs to operate CW and weak signal digital modes on our lower HF frequencies including 60 meters. Keep Our Digital Transmissions Legal on 60 Meters If you wish to assist in this enforcement and education matter, you may consider requesting your Official Observers to document frequency centers, call signs, dates and times of 60 meter signals in violation for submission to ARRL headquarters.īelow is a detailed write up on this matter (also posted at ARRL Sacramento Valley Section) for your reference. This matter may adversely impact the National Telecommunications and Information Administration's (NTIA) disposition to expand our access to 60 meter frequencies as proposed in the ARRL's Petition for Rulemaking. Despite repeated explanations of the regulation in public forums, some US amateurs continue these infractions either through ignorance or express disagreement with the rules. A serious FCC rules enforcement issue concerns the increasing number of US radio amateurs' radio CW and digital emissions on 60 meters that are out of compliance with Part 97.303(h) or on completely unauthorized frequencies.
