Development of the radio in africa

We have been hearing a lot about long range contacts, all being made on SSB. Well FM is now days the most popular mode and it has become popular as a result of all the repeaters which that work on FM. These repeaters are there to extend the operating range on VHF and UHF and of course FM can also be used to make simplex contacts as well without using repeaters. Single Sideband on 2 Meters:

I have had folk in passing tell me topics that I should present on VHF and above, but no one has sent me information that I can compile and edit so that it can be presented on AR Today.


What about the newbies? Why not drop an email to vhfnews sarl. Let us now have a look at some news about the VHF and Above bands There is again very little in the way of VHF news being reported on the forums and elsewhere, but if you follow the activity of the 46 group on WhatsApp they are trying every day to establish long range VHF and UHF contacts.

All these contacts were made between These guys will also very quickly exploit a passing aircraft if they can, in order to make a contact. For this group the reception of the beacons is the first indicator whether the bands are open or not. In the absence of a beacon they will transmit CW and then wait for a reply that they are being heard, before changing to voice and attempting to make a contact on either SSB or FM.

Good progress has been made on this list. Please send information of the beacons to vhfnews sarl. The guys on the 46 Group also reported the beacons on WhatsApp. The VHF working group has a Skype meeting every 2 weeks and is progressing well with the quest to get a beacon operational in the centre of the country in the vicinity of Van Der Kloof.

A suitable site is being sought. A radio and a keyer are also being finalised.

If you would like to join the VHF working group at their next meeting on 29 November at The Noise workshop that took place yesterday was well attended and the highlight of the day was the very informative presentation by Paul van As of SurgeTek.

At least they now have a good idea of what they need to do to make their stations more lightening resilient. Proposals for papers and presentations are invited and should be sent to vhfnews sarl.

Thank you, Dick for being the first to volunteer to do a presentation at the workshop in February. Put the date 9 February in your diaries and come and enjoy the presentations provided and the knowledge shared.

You will be surprised and the number of old hands who attend these workshops, eager to learn something new. That is the beauty of our wonderful hobby. There is always something new to learn and experience. Well that is all the VHF and Above news for this week.

Please send your news snippets and information about activities on VHF and Above including information for the tutorial to vhfnews sarl.

The contest takes place on the second full weekend of October each year. A station may participate in all three periods. For amateurs around the world to contact as many other amateurs as possible during the three periods of operation using RTTY.

No RST report is required. Aim of the contest: Scandinavian stations will try to work as many non-Scandinavian stations as possible and vice versa.

For amateurs around the world to contact as many other amateurs in as many CQ zones and countries as possible. Observance of established band plans is strongly encouraged. RS report plus CQ Zone number of the station location e.

RaDAR operators are encouraged to be self-sufficient during each challenge, with not only power supply and communications equipment but food, water, protective clothing and shelter. All amateur bands are allowed including cross band contacts via amateur radio satellites.

The RaDAR challenge requires more than a minimalistic information exchange. Accurate information exchange is considered more important than a large QSO count. Call sign, name, RS T report and grid locator.

The grid locator of six characters is acceptable but should preferably be accurate to 8 or 10 characters for higher position accuracy especially for moving RaDAR stations. Contacts must be two-way point to point.TEA Bernard Sunley Foyer and Junior Common Room Foyer March 18, to Tea, Bernard Sunley Foyer and Junior Common Room Foyer.

South Africa as a hub for community radio development research Despite these challenges, South Africa is a leader in the media field. The AMDI reports that, among African nations, South Africa is by far the best served by local and national NGOs (with 36, such organizations, next to Uganda’s 6,).
