American Novice and Technician class licensees were granted CW and SSB segments on the 10 meter band as of 21 March 1987. [ 4 ] With the elimination of Morse code testing requirements for U.S. amateurs in February 2007, Technician-class licensees who have not passed a code test may operate with up to 200 Watts PEP using CW and SSB modes in a ...

The list of frequency ranges is called a band allocation, which may be set by international agreements, and national regulations. The modes and types of allocations within each frequency band is called a bandplan; it may be determined by regulation, but most typically is set by agreements between amateur radio operators.
Most high frequency radio propagation beacons are found in the 10-meter band (28 MHz), where they are good indicators of Sporadic E ionospheric propagation. According to IARU bandplans, the following 28 MHz frequencies are allocated to radio propagation beacons:
The digital segment is 10.13-10.15 MHz. The current band plan has telephony from 10.12–10.135 MHz, with CW only below 10.12. These are WIA [ 13 ] recommendations only as ACMA does not restrict Australian amateurs' modes within HF allocations beyond requiring less than 8 kHz occupied bandwidth per channel below 28 MHz.
Peak envelope power (PEP) is the average power over a single radio frequency cycle at the crest of the modulation. This is a Federal Communications Commission definition. PEP is normally considered the occasional or continuously repeating crest of the modulation envelope under normal operating conditions.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...
FCC amateur radio station license of Al Gross. In the United States, amateur radio licensing is governed by the Federal Communications Commission (FCC). Licenses to operate amateur stations for personal use are granted to individuals of any age once they demonstrate an understanding of both pertinent FCC regulations and knowledge of radio station operation and safety considerations.
