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 ...
To begin, report the frequency, date and time the station was heard. For medium-wave (AM) stations, the time should be that of the time zone in which the station is located. Thus, if a listener hears stations from the Eastern time zone of North America (such as Ontario and New York), EST or EDT should be given (depending on the time of year).

Global-IV: 2012: Leased for a shortwave propagation study [5] WWRB was last listed on the FCC frequency schedule in northern Summer 2021: 5.05 MHz from 2200-1300 UTC. [6] In February 2023, the 5.05 frequency was reallocated to WRMI, where it is used by Ted Randall (former engineer of 5.085 WTWW) for his "WRMI Legends" oldies service.
The 15-meter band (also called the 21-MHz band or 15 meters) is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications, and such use is permitted in nearly all countries.

To change this template's initial visibility, the |state= parameter may be used: {{Frequency list | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Frequency list | state = expanded}} will show the template expanded, i.e. fully visible.
The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal's readability, strength, and tone.
