USA’s FCC changed its rules for the Amateur Radio Service at 5MHz.
Here is a basic overview of the changes and rules in plain language, as they apply to the Amateur Radio Service in USA.
The new rules take effect at 0001 hours Local Time in each of the USA time zones, on 05 MARCH 2012. Note: This is late at night (just after midnight) on the evening of Sunday 04 March 2012, early morning Monday 05 March 2012.
The FCC adopted the use of the name “60 meter band”, to refer to 5MHz amateur radio in the frequency range 5330.5-5406.4 kHz, but USA hams are still only allowed to transmit on 5 specific channels in the band.
The FCC changed the rules to allow: Phone (Upper Sideband), RTTY, Data, and CW; with specific new limitations on the use of these modes.
Amateur radio is a “secondary user” in this band, and must not cause harmful interference to other services! Amateur Radio Service must accept interference from primary, other services, and other nations services.
Operators transmitting data or RTTY must exercise care to limit the length of transmission so as to avoid causing harmful interference to US Government stations.
General, Advanced, or Amateur Extra Class license only.
The maximum allowed power level is 100 Watts PEP (ERP) effective radiated power referenced to a halfwave dipole. If another type of antenna is used, the station licensee must maintain a record of either the antenna manufacturer’s data on the antenna gain or calculations of the antenna gain.
Upper SideBand Phone, Data, or RTTY transmissions may use dial (VFO) USB suppressed carrier frequency as listed. Transmissions must not exceed the 2.8kHz bandwidth channel. RTTY modes such as PSK31 must not exceed 60Hz necessary bandwidth. Data modes must not exceed 2.8kHz bandwidth. CW bandwidth must not exceed 150Hz bandwidth and the CW frequency must be at the center of the channel.
Section § 97.221 automatically controlled digital station, excludes the 5MHz channels.
For compliance purposes, please rely only upon the actual FCC rules.
