COMMERCIAL ANDREWS DISH SUITABLE FOR 5,7 GHz AMATEUR BAND – Pierre Holtzhausen, ZS6PJH, of Pretoria recently came into possession of an Andrews Dish antenna Model UHX8-59W similar to the type used in microwave networks. He has long term plans to use this on the amateur radio SHF bands. This is a 2,4 metre diameter Ultra High Performance Shielded antenna and dual polarized. Band One: 5,925 – 7,125 GHz, and Band Two: 5,725 – 5,850 GHz which almost covers the 5,650 – 5,850 GHz amateur band. The gain of this antenna is around 41 dBi. The current Tropo SARL record on the 5,7 GHz band SSB stands at only 151 km as established by Ivo Chladek, ZS6AXT, and John Sygo, ZS6JON, in 2003. The SARL EME record was recorded between Ivo ZS6AXT and W7CNK on CW in 1999 over a distance of 14 745 km. What has happened to all those dishes used by the GPO on their countrywide microwave network during the pre-satellite era?
CHINA SUCCESSFULLY LAUNCHES NINE AMATEUR RADIO SATELLITES – Nine Chinese satellites carrying Amateur Radio payloads were launched on 16 September 2015 at 23:00 UTC, separating from the Long March launch vehicle about 15 minutes later. China Amateur Satellite Group CAMSAT CEO Alan Kung, BA1DU, has said that four of the microsatellites and two of the CubeSats included in the launch have been designated as XW-2A through XW-2F. The other three satellites — a CubeSat, a nanosatellite, and a picosatellite — carry the designations CAS-3G, CAS-3H (LilacSat-2), and CAS-3I (NUDT-Phone-Sat), respectively. All of the new satellites have downlinks on 2 meters and uplinks on 70 centimeters. Satellite enthusiasts have been enjoying the sudden surfeit of spacecraft to work.
THE SECUNDA BACAR III BALLOON LAUNCH – The Secunda BACAR III balloon was launched at 06:34 CAT on 3rd October 2015. It reached a maximum height of 33 212 metres at 07:50 CAT before the balloon burst. Pravin Kumar, ZS5LT, reports: “I worked the parrot repeater from New Germany Nature Reserve, KG50ke, using an arrow antenna and my FT817 set to 3 Watts (really small battery pack). I had two full QSO’s (ZS6BWW, ZR6LJK and a Div. 4 station came in but was lost) then the parrot repeater went down, seeming like it was resetting. Any further QSO’s were impossible. The signals from the repeater when it was on was a solid S9+20 dB. I did not get any RTTY on 434,650 MHz USB/LSB – zero signal present, I dont know if it was on. Well done anyway guys, was the ayload recovered? Gavin ZR6LJK it was good to work you from KG50ke to your QTH KG43bt, a distance of 484 km with 3 Watts!”
FIRST TEP REPORT OF THE SEASON – Ian Roberts, ZS6BTE, says: “Seems there was a TEP opening last night. I listened around 7:30 pm SAST but heard nothing. IK0TA 50,050 MHz ZS6JON/b 18:12 on 28 Sept. 419 in JN61 South Africa EA5/G3XG etc. Several other reports from Portugal (VHF DXer): ‘Hi Ian, hearing the ZS beacons on 50,044 and 50.050 MHz tonight. Cameroon E2 noisy one and the 2 E4’s around also.’ Question – did anyone in ZS hear anything last night on 6m? Strange propagation. Ian ZS6BTE.”
GOOD VHF SIGNALS BETWEEN ZS2 & ZS5 – “Hi from East London. I had a phone call last night Wed. 29th from Dave, and was told/asked to get on to 144,300 MHz SSB. I heard John ZS2AH in E.L. talking to Dave ZS5DJup the coast in Ramsgate Natal. I broke in and joined the QSO. Signals were ranging from 59++ down to just hovering in/out of the noise. The RX signal strength varied between John and I and we are only 6 km apart, John being the one nearest the sea. It shows that RX conditions are very variable depending on your exact location/height. It is not always who has got the largest antenna. John has the larger aerial, but I was copying Dave far better. Then at other times in the past, John copied Dave better than I. Sometimes Ducting seems to only hug a narrow strip along the water edge. So keep calling and trying you never know who you may hear. Cheers Peter ZS2ABF.”
ZSEFN IS LOOKING FOR A VHF/UHF SSB TRANSCEIVER – Etienne Naude, ZS6EFN, is looking for a used but in good working condition VHF/UHF all mode transceiver. Can anyone help? His Cell Number is 082 553 0542.

Jan “Pine” Pienaar, ZS6OB, skryf: “Hier is 'n brokkie nuus net vir interessantheid. ZS60B was een van die 3e kleinste stasies wat deelgeneem het, al die ander stasies het met groter antennas stelsels en groter krag meegeding. ZS6OB is ook die lokale verspreider vir die DUBUS Internasionale Tegniese tydskrif, Lokale amateurs wat die tydskrif in 2016 wil ontvang kan my kontak voor die einde Desember 2015. ZS6OB plaas ook van tyd tot tyd artikels in die DUBUS tegniese tydskrif oor lokale ZS AMA aktiwiteite in die RSA. As daar ook radio amateurs in Suid Afrika is wat aktief met AMA [EME] aktiwiteite besig is kan hulle my gerus kontak ek sal graag die inligting in Dubus laat publiseer.”
