Radio Stations Attitude - Writing Useful Reception Reports @ DX Guide - DXing Info

Name and address

m1494_thmSo obvious in a printed report and yet it is amazing how many people forget to include it. In many cases your reception report may be processed by more than one department within the radio station. (i.e. the Engineering and Programme departments), so we advise you to include your name and address on each sheet that you use. Either print your name and address in block capitals or type it. Many replies have failed to reach their destination because it was impossible to read the name and address of the sender. Signatures are often very difficult to decipher.

The station address
Always address your letter to the correct person. Avoid the use of titles like 'The Director General', 'Head of Programmes', etc, if you want a QSL or wish to make programme suggestions. It is very unlikely that the station director or the general management will be the people responsible for answering the letters. If a particular programme presenter made a point on the air that you wish to take further, then send the letter to her/him by name, c/o English Section, Radio XYZ, etc. This should ensure that the right person opens the letter. Alternatively writing to the programme by name: 'Research File', English Language Service, Radio Netherlands, P.O. Box 222, 1200 JG Hilversum, Holland', increases the chances that the producer of that programme will see that letter.

Date
It is best to write this out fully (i.e. January 11th 2002) since European shorthand notation, such as 11.01.02, has different meanings depending on where you live. Naturally, it is usually obvious which meaning is implied, but writing the date out in full ensures there will be no mistake.

Time
This should be stated in "Co-ordinated Universal Time" (usally shorted to the French version of the abbreviation, i.e. UTC), which is the standard used by the majority of international broadcasters. The term "Greenwich Mean Time" (or GMT) is still being announced by a few stations, e.g. BBC World Service in London. But no conversion is necessary as both terms are interchangeable. Unless you're a scientist interested in accuracy to milliseconds, just assume that 1000 GMT = 1000 UTC.

If you are in doubt as to the time difference between your own local time and UTC, simply listen on the hour or half-hour to most international broadcasters (i.e. Radio Netherlands, Deutsche Welle, VOA) who will announce the time in UTC. Simply work out the difference in hours between your time and UTC. Use this information to make a conversion table to keep by your radio for handy reference or check out the table in publications like "On Target". Alternatively, set a clock by your receiver to work on UTC. Note that UTC is always the same and is unaffected by local changes, summer or winter time . All stations use the 24 hour clock system, so when you compile a report, avoid the use of AM and PM which can lead to confusion, e.g. 18.30 = 6.30 pm.

Frequency
This describes the point on the dial that the signal came in, usually indicated in kilohertz (or kHz). The frequency that you quote should be accurate to within about 5 kHz, i.e. saying 'I heard you on about 6 MHz' is not sufficient. If, however, your set cannot give accurate frequency read out from the shortwave dial, say so in your report. The term kilocycles (kcs) is an older expression, but means the same as kHz. If you know that a station is using more than one frequency at the time you're listening, check as many of these as possible, and note how well each of them is received.

A report on one single frequency on one day has little value these days, though the station will probably still send you a QSL card. The experienced listener does one, or both, of the following:

  1. Notes the reception quality of a number of frequencies carrying the same programme over a period of three to six days.
  2. When a particular channel is blocked by interference, a check is made to see whether another frequency nearby is more suitable as an alternative (but see later notes).

Metre band

Not really necessary if you have noted the frequency correctly. If you only have 'metres' marked on your set, then quote this in your report, though few listeners quote them these days. If you need to convert metres to kilohertz, then use the following formula:

300,000 =

Frequency in kHz
_________________

Wavelength in metres

Receiver
This is a useful piece of information to the frequency department, so don't forget to include it in your report. If you are suffering bad reception, one of the first things that will be checked is the type of receiver that you're using. Remember that the brand name and model may not be known in the country where the report is received, so decide whether your receiver is a "domestic" type (i.e. has mediumwave, or VHF/FM on it as well as shortwave?) or is it a "communications" type (i.e. made primarily for listening to shortwave broadcasts between 3 and 30 MHz?). If you can quote the description given in the manufacturers brochure, this is usually sufficient, (e.g. 8-band SW dual-conversion portable).

Antenna
cobj003_thm
Also a useful piece of information and frequently forgotten. Transistor portable radios usually perform adequately on a built-in antenna of the 'telescopic rod' variety. If you are using a piece of wire or a random length hung out of the window, the best description is a 'random longwire aerial'. Specially built antennas such as 'magnetic long-wire balun', 'inverted L' or 'dipole' should be mentioned by name if possible.
