Welcome, and many thanks for reporting in.  A bulletin of news and information is normally broadcast every Tuesday evening at 19:00 on our Centurion 2-meter repeater, which is situated at our Rooihuiskraal site, on a frequency of 145,775 MHz with a regular simultaneous broadcast on our Centurion 70 centimeter repeater, which is situated at our Keevykop site, on a frequency of 439,050 MHz.

HAMNET REPORT 11TH OCTOBER 2020 – quick summary

This is part of the report of Dave Reece ZS1DFR reporting for HAMNET in South Africa.

Greg Mossop, G0DUB, has reported on the IARU Region One virtual meeting held 2 weeks ago. He notes that 17 countries were represented amongst the attendees. Attention was given to possible applications for space at 40 and 60 MHz for emergency communications. Data modes are being explored, especially JS8Call, FSQ, ARDOP and GARIM on HF, and New Packet Radio using higher speed data modes. IARU Region One is very diverse, with large organizations of up to 1700 members in some countries, while others have 10 in their whole country. Hamnet in the Western Cape was invited to participate in a City of Cape Town Disaster Simulation Exercise again this year, yet again practising the management of a nuclear power station disaster at Koeberg. This took place on Thursday the 8th, and we had operators stationed at Koeberg power station, as well as at the Disaster Management Centre at Goodwood. Our mobile UHF repeater was installed on a high site in Green point, and was accessible from both operations centres, while the 145.750 repeater on Kanonkop in Tygerberg was also used. Useful experience was gained, and valuable input from our operators provided to the City.

Four CW Contacts per Day Certificates

Just a reminder…..The ZS-CW group have started a new initiative to get more people active on CW on all bands, this will get you a certificate at the end of the year. Make four CW contacts per day and qualify for the following certificates: 200 to 250 days – Bronze certificate, 250 to 300 days – Silver Certificate and 300 plus days – Gold Certificate. Send proof of your contacts by Excel log submission to Mike, ZS6MSW ( or Andy, ZS6ADY (

Other CW news…Mike ZS6MSW reported on Facebook that so far 27 Hams consider themselves very regular ops, within our country. He is doing this Census to determine the positive, and if any decline of CW, so we know where to focus our efforts, to get up to speed with the rest of Europe and the USA. They are currently holding CW classes on the ZS6TJ repeater 145.650 88.5 tone, every Monday 7pm SAST and hosted and Tuesdays are hosted by Steve ZS6XU on a  less formal basis. Two operators wanted to know if they qualify to be on the CW data base, as PC CW driven ops, and sorry the answer is no. You must be physically using a key, and be fairly regular. You can email Mike  @

For the Sattelite enthusiasts….. Reminder! On September 1, 2020, an FM transponder was installed on the International Space Station in the Columbus module. The transponder consists of a modified JVC Kenwood D710GA. On September 2 at 01:02 UTC the system was activated. Frequencies: UPLINK: 145.990 MHz Tone: CTCSS 67 Hz, DOWNLINK: 437.800 MHz. I had feedback that it is working but qso’s are short as if the squelch seems to be a bit high.
