A reception report is a means by which radio stations receive detailed feedback from their listeners about the quality and content of their broadcasts. A reception report consists of several pieces of information which help the stationverify that the report confirms coverage of their transmission, and usually include the following information:
The listener's location relative to the station is also useful; this indicates how well the station's transmitter is performing and in which direction its antenna is beaming the signal. The station also evaluates a reception report in light of the listener's receiver and antenna. Upon receipt of a correct report, a broadcaster sometimes issues a letter or postcard to the sender, thanking them and confirming that the details are correct. "QSL" is part of the amateur radioQ code, meaning "I acknowledge receipt". One aspect of DXing is collecting QSL cards and letters from stations heard. QSLing a radio station involves writing an accurate reception report, mailing it to the station and awaiting a reply. Since QSLing is a voluntary act on the station's part, several techniques are used to improve a listener's success rate.
Useful reception reports
Station engineers and other personnel are primarily interested in whether or not their station is heard, and how well; therefore, a complete and accurate reception report is generally appreciated. To begin, report the frequency, date and time the station was heard. For medium-wave 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, EST or EDT should be given. Stations in the Central time zone use CST or CDT, which is one hour earlier than Eastern time. If a listener is uncertain of the time zone, they should clearly indicate their local time or even better use UTC It is helpful to jot down programming as it is heard. Useful details include:
Station identification
Program name
Names of station announcers
Commercials is usually sufficient. International shortwave broadcasters are familiar with the SINPO code:
Signal strength
Interference
Noise
Propagation disturbance
Overall reception quality
Each letter receives a value between 5 and 1, where 5 is the best and 1 the worst. Many shortwave listeners desire nothing more than music and news from a broadcaster; however, for DXers a QSL collection is tangible proof of what they have heard. Some listeners use pre-printed forms if they are unfamiliar with the language spoken by station personnel. While major international broadcasters have not required return postage for a QSL, the growing popularity of e-mailed reception reports and e-QSLs has largely eliminated the necessity for international reply coupons, mint stamps from the verifying station's country or "green stamps".
