Reception report

Last updated

A reception report is a means by which radio stations (usually short- and medium-wave broadcasters) 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 station verify 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(s) 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 (known as a QSL card) to the sender, thanking them and confirming that the details are correct. "QSL" is part of the amateur radio Q code, meaning "I acknowledge receipt". One aspect of DXing is collecting QSL cards and letters from stations heard (similar to a birdwatcher's "life list"). 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 (whether by postal or e-mail) is generally appreciated. 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). Stations in the Central time zone (such as Chicago) 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:

The purpose of providing this information is to prove to the station that you heard their program and not that of another station. The more detail a listener can provide, the better the chance of eliciting a QSL. Include information, also, about how well the signal was received. For medium-wave reports, an indication of signal strength and any interference (co- or adjacent-channel interference, with identity of interfering station if possible) is usually sufficient. [1] International shortwave broadcasters are familiar with the SINPO code:

Each letter receives a value between 5 and 1, where 5 is the best and 1 the worst. Many shortwave listeners (known as "program 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. [2] 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 (IRCs), mint stamps from the verifying station's country or "green stamps" (US dollar bills).

Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz ; above the medium frequency band (MF), to the bottom of the VHF band.

International broadcasting, in a limited extent, began during World War I, when German and British stations broadcast press communiqués using Morse code. With the severing of Germany's undersea cables, the wireless telegraph station in Nauen was the country's sole means of long-distance communication.

<span class="mw-page-title-main">Medium wave</span> Radio transmission using wavelengths 200-1000 m

Medium wave is the part of the medium frequency radio band used mainly for amplitude modulation radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than frequency modulation stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals. This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet.

<span class="mw-page-title-main">Longwave</span> Radio transmission using wavelengths above 1000 m

In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'.

<span class="mw-page-title-main">Radio broadcasting</span> Transmission by radio waves intended to reach a wide audience

Radio broadcasting is the broadcasting of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (radio). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM, FM radio stations transmit in FM, which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB, HD radio, DRM. Television broadcasting is a separate service that also uses radio frequencies to broadcast television (video) signals.

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. The code was developed in 1934 by Amateur radio operator Arthur W. Braaten, W2BSR, and was similar to that codified in the ITU Radio Regulations, Cairo, 1938.

A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report formats are usually designed for only one communications mode or the other, although a few are used for both telegraph and voice communications. All but one of these signal report formats involve the transmission of numbers.

Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz. Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of radio reception and collecting official confirmations that document their reception of distant broadcasts (DXing). In some developing countries, shortwave listening enables remote communities to obtain regional programming traditionally provided by local medium wave AM broadcasters. In 2002, the number of households that were capable of shortwave listening was estimated to be in the hundreds of millions.

Radio jamming is the deliberate jamming, blocking or interference with wireless communications. In some cases, jammers work by the transmission of radio signals that disrupt communications by decreasing the signal-to-noise ratio.

HCJB, "The Voice of the Andes", was the first radio station with daily programming in Ecuador and the first Christian missionary radio station in the world. The station was founded in 1931 by Clarence W. Jones, Reuben Larson, and D. Stuart Clark. HCJB now focuses on Ecuador with unified programming on FM at 89.3 MHz in Pichincha, at 92.5 MHz in Manabí, at 96.1 MHz in Tungurahua and Cotopaxi, at 98.3 MHz in Esmeraldas and with separate programming on AM at 690 kHz. Broadcasts in Spanish and indigenous languages on 6.05 MHz (1 kW), continue on an intermittent basis with a new solid state transmitter which in 2017 replaced an older (5 kW) transmitter. These broadcasts were not listed on the HCJB English website as of February 2016.

DXing, taken from DX, the telegraphic shorthand for "distance" or "distant", is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens band radio or other two-way radio communications. Many DXers also attempt to obtain written verifications of reception or contact, sometimes referred to as "QSLs" or "veries".

SINPO, an acronym for Signal, Interference, Noise, Propagation, and Overall, is a Signal Reporting Code used to describe the quality of broadcast and radiotelegraph transmissions. SINPFEMO, an acronym for Signal, Interference, Noise, Propagation, frequency of Fading, dEpth, Modulation, and Overall is used to describe the quality of radiotelephony transmissions. SINPFEMO code consists of the SINPO code plus the addition of three letters to describe additional features of radiotelephony transmissions. These codes are defined by Recommendation ITU-R Sm.1135, SINPO and SINPFEMO codes.

MW DX, short for mediumwave DXing, is the hobby of receiving distant mediumwave radio stations. MW DX is similar to TV and FM DX in that broadcast band (BCB) stations are the reception targets. However, the nature of the lower frequencies used by mediumwave radio stations is very much different from that of the VHF and UHF bands used by FM and TV broadcast stations, and therefore involves different receiving equipment, signal propagation, and reception techniques.
