We start the bulletin with news of 2silent keys

It is with regret that we learnt that Paul Potgieter ZS6PSP, passed away earlier in this week. Paul was known as an active amateur but struggled with his health in recent years. We extend our deepest condolences to his wife, his family and friends.

It is with sadness that we have to announce the sudden passing of OM Jopie van Lill, ZS6JVL last week. He was involved with the East Rand Radio Club for many years. Our deepest sympathies goes to his wife Anett.


In the news today





Stay tuned for more on these and other interesting news items.

** HAMNET is planning a national 24 hour communications exercise late October 2015. This is the fourth edition of the HAMNET Communications Exercise, which was previously held as a "Winter Exercises" The exercise will be held from 12:00 on the 24 October until 12:00 on 25October 2015.

As in the past, teams will consist of at least of 4 members, of which the leader and at least half the team must be HAMNET members. Teams may deploy themselves at any location and HAMNET are again hoping to activate as many Disaster Centres as possible. Entries will be accepted on a "first come, first serve basis" for locations, to avoid having teams too close to one another. Teams are encouraged to find locations that are of some interest and remote to their normal points of operation.

The theme of the exercise will be "black out" where all stations are required to operate all activities off the power grid. This will include radio equipment, lighting, cooking and any other related activities. Remember that this is not a competition or contest, the exercise is held to afford teams an opportunity to learn about their capabilities and very importantly their shortcomings.

The overall success will be judged on how teams co-operate with each other. Another new concept this year will be the "priority" messaging. At various times a random team will have to get a message through to another team. The messages and times will not be disclosed before the start of the competition and the teams must use all resources at their disposal (except telephones or cell phones) to get the messages through to another team."

The closing date is the end of September to allow the organisers to make their final preparations and distribute the information packs to team leaders. The entry form must be completed and sent to Entry forms will be available on - click on HAMNET in the left-hand side column.

The heartfelt thanks of the management and members of the HAMNET Gauteng South division is herewith expressed towards Martin Nortman ZS6TMN and his XYL Mina ZS6MNT for the donation of a new axle and wheels for the HAMNET trailer to the value of R6000-00.

Thank you Martin and Mina for the generous contribution to emergency communication.

HAMNET Gauteng South meets on the first Thursday of each month at the East Rand Radio Clubhouse at Arrowe Park in Benoni.

For more information contact Chris Gryffenberg ZS6COG.

HAMNET is a public benefit organisation.

**At the 50 year amateur radio festival of the Sasolburg Radio Club, a monster loop antenna was erected. This loop antenna is one of the largest loop antennas recorded in South Africa.

**Leon Korkie, ZS1MM, of Denel Overberg Test Range informed us about an interesting EME test conducted on 1296 MHz with Dr. Lindsay Marcus on the KAT-7 radio telescope with a gain of 44,3 dB.

On the transmit side Leon programmed his call sign on a PIC at very slow Morse with 2 to 3 seconds per dot, as this is the shortest integration time of their receivers. Leon used this to key a Rhode & Swartz signal generator, which was fed into his 10 Watt solid state amp via about 25 metres of half inch Heliax so that he could have the amplifier as close to the antenna feed as possible. This feed is mounted on a 15 foot auto tracking antenna that was slaved onto the Moon at a time when there was very little Sun on the Moon so as to have minimum noise. They used the central computer system of the test range to do the slaving. There was a beacon pointing at the Moon aswell causing some interference so Leon QSY a little up in the band to get rid of that.

Dr. Lindsay Magnus confirmed the reception of the signal with full scale chart recordings and also referred to the interfering signal that turned out to be the EME beacon on 1296,000 MHz radiated from Ariceibo, Puerto Rico.

How many are aware that after Karl Jansky accidentally discovered radio emission from the centre of the Milky Way on 20 MHz, it was a radio amateur who pioneered radio astronomy in the early days. Grote Reber, W9GFZ, mapped the radio skies in the Northern hemisphere and continued throughout WWII. He used a homebrew dish antenna on a frequency of 160 MHz.
