HF UPDATE WITH ZS4BS (updated 20 October 2014) 

3B8 & 3B9, Mauritius and Rodriguez Islands. Olof, G0CKV, will be active from both Mauritius (AF-049) and Rodrigues Islands (AF-017) starting mid-week through late November. His tentative schedule is as follows: 22 October to 12 November - Mauritius; call sign 3B8HA 16 to 22 November -

Rodrigues Island; call sign 3B9HA- Olof will use a basic setup (dipoles for 20/15/10 m) at Mauritius, operating mainly CW, but will be active in the CQ WW DX SSB Contest (25 and 26 October) as a Single-Op entry before he heads to Rodrigues Island. QSL via G0CKV, direct, LoTW or eQSL. On Rodrigues Island, he will take a different approach and use his K3 radio into SpiderBeam poles and beverages for the lower bands. Activity will be holiday style. He will return to Mauritius to be part of the 3B8MU team for the CQ WW DX CW Contest (29 and 30 November) in a Multi-Op entry. The 3B9MU operators mentioned are Olof, G0CKV, Kazu, JK3GAD, Seppo, OH1VR, Jorma, OH2KI andOlive, W6NV. 

3Y/B, Bouvet. The is reporting, "Last Wednesday (a well known op) received word from the Norwegian Polar Institute, that, 'It's a go for a one man DXpedition for 3 months, time frame half January 2016 through half April 2016 to Bouvet Island." Bouvet Island (AN-002) is ranked number 3 in the DX Magazine's 2013 Most Wanted Countries Survey (the results of the 2014 survey will not be known until January 2015). The last two operations from Bouvet took place - December 2007 - by Petrus, ZS6GCM, as 3Y0E and December 2000 - Chuck, N4BQW, as 3Y0C. Both operations were one man operations. The last large DXpedition that took place there was 3Y5X (December 1989). Stay Tuned For Updates!           

5R, Madagascar (5R8M Press Release #001). Mediterraneo DX Club reported on Friday 17 October [edited]: "In less than few days, 5R8M, Nosy Be Island (AF-057) the DXpedition organized by the Mediterraneo DX Club, in Madagascar from 21 October to 4 November, will be on air. Recently we have had new great arrivals and now our complete team, with so many well know and experienced guys, is the following - Antonio, IZ8CCW (Team Leader); Jean-Jacques, F5NKX; Gabriele, I2VGW (co Team Leader); Marco, IZ2GNQ; Francois, ON4LO; Michele, IK5ZUI; Eric, ON7RN; Mario, IK4MTK; Alain, F6ENO; Fabio, IK4QJF; Patrick, F2DX; Karl, OE3JAG; Michel, F5EOT; Ovidio, YO9XC; Henri, F1HRE, and Feri, YO5OED

The whole team is very motivated and so ready to work hard 24/24 hours each day to give the greatest number possible of DXers from all over the world the greatest number of possible new ones, bands/modes, with four stations (2 CW; 1 SSB and 1 RTTY) plus maybe a mixed station more and really daily time monitoring Six metre propagation. If, as all of us wish, the internet connection will allow it on our official Web-site, we'll keep in touch every day with the DX community and we'll update our log in real time. During our permanence on Nosy Be, we kindly ask you to send any question only to our  pilots IK7JTF (for Europe), N1DG (for USA) and IK0FTA for Six metres. 


African Tours (Update). As mentioned last week, Nick, G3RWF, is heading back to Southern Africa for a 5-week holiday starting in Lesotho and being active as 7P8NH between 11 and 14 December. Nick informs OPDX that this is "real holiday" with the entire family coming to Southern African between Christmas and the New Year. However, he will be there longer with his wife, Liz. Nick states [edited], "I shall be on the air from South Africa from about 18 December to 5 January as ZS1/G3RWF, and then from Namibia from about 6 to 13 January as V5/G3RWF. All CW only (taking my K2)." Listen for him on the higher bands on CW (no SSB). He "doesn't anticipate any 80 or 160 m (and not 6 m for those who always ask)." Nick also mentioned one other thing to OPDX that his 7P8 license is good for a year and he may well return there sometime not too far off. QSL via G3RWF.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM (19 October 2014) 


AMATEUR RADIO 100 YEARS AGO! – World War I began on 28 July 1914, and all amateur spark transmissions with its damped waves, using Morse Code, came to an end. In 1904 the first spark transmitting licence was issued to W. E. Dixon Bennett, (FO-A3V, ZS4F, ZS4W, ZS5EG) in Pretoria, and amateurs could choose their own call signs. During the war years Edwin Howard Armstrong invented the regenerative and super-regenerative receivers based on Lee de Forest’s triode tube. Many years later he developed the superheterodyne receiver as well as Frequency Modulation. His continuous wave oscillator formed the basis of all future transmitters. With amplitude modulated (AM) broadcasting looming on the horizon on long and medium waves when the war ended, governments began to realize the true value of the radio spectrum. There was no place for radio amateurs on the air anymore. Hiram Percy Maxim, president of the ARRL, made many trips to the US Congress to persuade them to reallocate some radio spectrum for amateurs, and they finally acceded to his request by granting all the useless wavelengths below 200 metres for amateur use. This is where radio amateurs made their greatest contribution to radio science by discovering F-layer DX propagation at night on 160 metres. John Samuel Streeter A4Z (FO-A1A, ZS1W) who in 1919 became the first licensed amateur in Cape Town, experimented with AM and made weekly musical broadcasts to the public. He also had the honour of working the first DX station, a US ham 1CMX at Fall River, Connecticut, on 36 metres. In 1922 he received his new call sign FO-A1A. The South African Radio Relay League (SARRL) was founded in 1925 and all S.A. amateurs were members. The FO series of call signs was changed four years later to the ZS series by the Government of the Union of South Africa. Those were the days! (Read more in “ The Dawn of Amateur Radio in South Africa” on the General Forum). 

WSPR DX ON 50 MHz – Johan Visagie, ZS6AF, at Nelspruit reported about experiments conducted with the digital mode, WSPR, on 50,293 MHz with Gideon Grobelar, ZS6GJG, at Phalaborwa about 180 km way, and that with a dipole. Gideon runs 20 Watts and Johan received him at –12 dB to –13 dB, but they cannot communicate with each other. Both of them heard KD4YDD over a distance of 13 800 km, as well as VA3XCD at 13 500 km during last week. 

EME NEWS BY JAN “PINE" PIENAAR ZS6OB – Moon conditions during the past 2 weeks have varied from good to challenging and sky temperatures went from very high reaching a maximum of 303,8 Kelvin on the 1st October to a low of 231 Kelvin on the 7th October. Sky temperature is currently on the increase again and today we have 415 Kelvin High sky temperature occur when the moon travels through sections of the sky where there is noise caused by terrestrial constellations and stars. Degradation is fair at –4,4 dB. Moonset today will occur at 06:32 UTC. Declination is at 17,7 degrees north of the equator. The Moon position will continue moving further north of the equator during the next week. Local operators active during the past 2 weeks were ZS6WAB, ZS6JON and ZS6OB There was activity from LU, CX, VK, ZL, Europe and State side. Conditions varied from only working the big guns to single antenna, low power stations. 

VHF IN GAUTENG – “After being away for 2 weekends in a row I am glad to say that I fill up more than a page in my logbook this weekend, a total of 27 contacts. Conditions were good this morning (12 Oct.) and most stations could work Jerry ZS6BTL with his 12 G2BCX antenna. Jan ZS6HA from Ermelo was on his post but QSB made contacts with Jan difficult. Thank you Theo ZS6TVB for activating SOTA ZS/GP-012 on Sunday afternoon and made use of 144,300 MHz USB to log stations in Gauteng. Please remember that VHF/UHF Meeting and Braai will be on 1st November at the Westrand Club House, everybody is welcome. So far it looks like we will have a good turn-up for the day. I am also pleased to report that the activity on 144,300 MHz is not just limited to week-ends, stations were active on the frequency just about every evening. Most of the stations I heard were from the Kempton Park and Johannesburg area. Come and join us next week-end from 06:00 to 08:00 CAT or give a call on 144,300 MHz when you have time. On Tuesday morning (14 Oct.) the ZS4N beacon (144,415 MHz) at Bloemfontein was 5/9 over distance of 371 km, and the ZS6WAB beacon (144,410 MHz) at Polokwane was also 5/9 over 300 km. 73 Carl ZS6CBQ”. 

NEWS FLASH! COMET PASSING MARS ON SUNDAY – A comet as hefty as a small mountain will pass mind-bogglingly close to Mars on Sunday, approaching within 140,006 kilometres at a speed of 202,767 km per hour.

What is Amateur Radio ? 

Tell me more  about Amateur Radio

Radio Amateurs, or "Hams" use two-way radio communication to make contact with other radio amateurs all over the world. They are even able to use satellites and on occasion speak with astronauts. Radio Hams can do this from home or while mobile in cars, boats or on foot.

Radio Hams have a full range or communication modes at their disposal. These include plain voice, Morse code, numerous digital computer modes and even graphical modes like television. As a licensed amateur radio operator you will be able to join in experiments using all these modes.

mateur radio can be enjoyed by young and old, male and female, even the most severely disabled can make friends around the world from their own home. This hobby knows no boundaries.
