In the news today:




You are listening to ZS6SRL. Stay tuned for more detail on these and other important and interesting news items.


The South African Amateur Radio Development Trust has revised the 2007 construction competition to an open competition in which the entrant can decide what he or she would like to design and build.

Enter your idea in as much details as possible. Five entries will be chosen and provided with up to R1000 each to construct the project. The entries must have application in amateur radio. The five projects will compete for one of two FT2800M transceivers sponsored by the Overstay, the distributors of Yaesu. Visit for full details.


Recently Dick Stratford, ZS6RO, set up a server on APRS which can be used to obtain Call book information from anywhere in the APRS international network. APRS, the acronym for Automatic Position Reporting System, was developed by Bob Bruninga, WB4APR. The system uses amateur radio to transmit position reports, weather reports, and messages between users.

When querying a local South African callsign, the SARL database is used. When a DX callsign is queried via APRS, the QRZ.COM database is used in real-time. The same databases are used when querying from the packet radio network.

As the SARL Call Book is updated weekly, this database is searched first because its South African content would be more accurate. If the information is not found, a search is then made in real-time at QRZ.COM's database on the Internet.

To use this facility when operating APRS and assuming one is using the APRS program - UI-View, open the window to send a message and in the "TO callsign" field, type ZS6RO-WI ("WI" stands for "WHO IS").

Then in the "MESSAGE" area, type "F Callsign" and Enter. (The Callsign being any Callsign you wish to look up). ("F" stands for "FULL Information"). One can just type the Callsign and a one-line summary of information on that Callsign will be received via APRS.

Instead of a Callsign, one can type "F SARL" for example. This will give the phone number and email address of the South African Radio League. Other country's Radio Amateur Leagues' information can also be retrieved - for example, RSGB, DARC, etc.

To update your personal Call Book information, South African amateurs should send updated information to

A Fox hunt will be hosted at the East Rand Radio Club at their club house in Springs at 09:00 on 19 May 2007.

The fox hunt will be followed by an APRS Interest Group Meeting at 14:00 at the club house.


Hannes Coetzee, ZS6BZP, reports that the expected solar activity will continue at very low levels. The geomagnetic field is expected to range from unsettled to active levels on 20 May. The expected Effective Sun Spot number for the coming week will be less than 20.

20 m and 15 m will provide best opportunities for DX. There is a possibility of 15 and 20 m openings towards India from about 06:00 and again at 13:00 CAT. Conditions are going to be challenging towards Australia.

From about 16:00, there may be good 15 and 20 m openings towards Europe. Contacts to the USA are going to be very challenging. For the CW and digital enthusiasts it may also be worth monitoring 10 MHz.

Although the predictions may not be too enthusiastic, HF always has the capability to surprise you as was once again demonstrated with the ZS1 and ZS3 expeditions this past long weekend. You will never know what you are missing unless you switch your rig on, listen and also call CQ.

Please visit for further information.
