Writing for Radio ZS

Do you have a story that will be interesting to other radio amateurs? Have you recently discovered something interesting by experimenting? Do you have a special interest that makes you an expert on some or other aspect of amateur radio? Do you have some amateur radio related photograph for the cover page of Radio ZS? If so, and you wonder about the writing of an article or the presentation of the material, please contact the editor. Contact details are given above.

Here are some helpful guidelines for those interested in submitting articles for Radio ZS.

Electronic Text

Study the articles in Radio ZS and follow the format of titles, subtitles, etc. Radio ZS uses 12pt Calibri for ordinary text. Select English (South Africa) for English articles. En Afrikaans vir Afrikaanse artikels!

Please do not underline titles and remember that tables have to fit an A4 page. The preferred formats are MS Word, Open Office or RTF, but ordinary TXT files can also be processed.

Please do not include graphics in the text but do indicate where it is intended to go. Submit graphics as separate files. It is difficult for the editor to devote five or more pages to one article – 3 to 4 pages also better hold the reader’s attention.


Try to submit clear photographs – photos of groups for example, often print so poorly that individuals are not even recognizable. Take photos against a light background – especially photos of electronic equipment.

The format of graphics files can be .jpg. This format creates small files and is suitable for the black and white photos used inside Radio ZS. It is not suitable for cover photographs – these should be in bitmap (BMP) or TIF format. The resolution of photos is to be no less that 300 dots per inch. Line drawing will probably be decreased in size to fit the A4 format, so use thick lines and large captions to keep it legible.


Material taken unchanged from other magazines or books cannot be used without permission. When submitting such material, please include the letter from the original publisher giving permission for re-publication of the material. Should you, however, rewrite the article, say to adapt it for local conditions, it can be used without permission.

Other IARU Member Societies may on written approval from the author and the editor of Radio ZS, reproduce material published in paper or digital form, for which the publishing author holds the copyright. Such approval shall not unreasonably be withheld. Material taken for other member societies’ publications in this way shall have a source and originator acknowledgement included on publication.

Large files

Large files are difficult to e-mail and travel through the net slowly. Consider zipping large files to decrease transmission time or send separate message each with one file attached.

Should you have any other questions, please contact the editor. He will gladly help you, as it is much easier than getting another contributor.
