The IARU HF Championship is taking place over the weekend of 14 and 15th July. The SARL takes part in this contest every year using the call sign ZS9HQ. The object is to contact as many other amateurs as possible, especially IARU member society HQ stations, around the world. This is an 24 hour contest so there are lots of slots available. The 24 hours are divided up into hourly slots. If you are interested in being part of the ZS9HQ team, you can operate from your home QTH, please contact Geoff Levey, ZS6C at

The Editor of Radio ZS thanks those members who contacted him following the SARL Communication about an article from 1981 required by a Dutch Radio Amateur. The article in question was found in the July 1983 issue of Radio ZS by Gert Botha, ZS6GC, who scanned it and sent it to the editor. Georges Schleger also provided a scanned copy, ZS1II. Thanks also to Neil Holmes, ZS2AI, Nico Oelofse, ZS4N, and Dudley Garner, ZR6AFT for their responses. The article has been sent to Stefan, PA3ADJ in Molenhoek.

On the Radio ZS download page on the League web site, you will find copies of Radio ZS from the July 1947 issue up to the June 2018 issue. But there are numerous gaps in the listing, for example the July 1983 issue, which we would like to fill. Have a look at the list and if you have any of the missing issues, please contact Geoff Levey, ZS6C to find out how the issue can be scanned and uploaded. Geoff can be contacted at


The RTL-SDR site highlights the work of Humpelstilzchen in getting a robot to drive towards a 433 MHz beacon transmitter. The experiment used a 433 MHz module to send out an FSK beacon. On the robot, two antennas are used for the time difference of arrival/pseudo-doppler direction finding technique and PIN diodes are used to rapidly switch between the antennas. A GNU Radio script running on a HummingBoard single board computer computes the TDOA/pseudo-doppler algorithm. Read the RTL-SDR post at


On 28 May, the IARU Member Societies completed voting on the admission of the "St Kitts-Nevis-Anguilla Amateur Radio Society" (SKNAARS) to the International Amateur Radio Union as the representative of the radio amateurs of the Federation of St Christopher St Kitts) and Nevis. SKNAARS ( does not claim to represent Anguilla, which is already represented in the IARU by the Anguilla Amateur Radio Society; the inclusion of Anguilla in the name of SKNAARS dates to an earlier time. With 56 affirmative votes required for admission there were 62 affirmative votes cast, with no dissenting votes. SKNAARS thus becomes a member of the IARU and of IARU Region 2.


Hannes Coetzee, ZS6BZP, reports that the solar activity is expected to be at low levels. Currently there are 3 sunspots visible with AR2715 being the source of C-class solar flares.
If you want to do your own frequency predictions, the expected effective sunspot number for the week will be around seven. The 20 and 30 m bands may provide lots of DX fun. Please visit the website for further information.
