7Q, Malawi (Update/Postponed). Roger, ZS6RJ, and members of the Black Mamba Contest & DXpedition Team, have informed OPDX the following [edited]: "Due to work commitments, the team has changed the original timing of the 7QAA DXpedition from November 2014 to the following fixed dates in March 2015:   10 member CW team active between 11 and 21 March, and 10 member- SSB/RTTY team active between 22 March and 1 April.

Each team will operate 4 stations on the air together. Equipment will be 2x Elecraft K3's, 2x Kenwood TS-590's and 4x Expert 1K or 1.3K FA linear amplifiers. Antennas are 4x NA4RR hexbeams at 40 feet each with Yaesu rotators, 2x inverted L's with remote MFJ 1.5Kw tuners for 40 through 160 meters and K9AY receiving antennas. The SSB team will also participate in the CQWW WPX SSB Contest, and also operate some additional CW and PSK.

Both teams will be active from 160 through 10 meters. Daily free LoTW and Clublog uploads will be provided, and we will use the band-slot tracking feature in Clublog to promote a competitive spirit amongst the DX fraternity. They feel due to the extended 20 day operating period there will be ample time to work the "little pistols" as well as the band-slot chasers. QSL cards will be available after the event too - details of QSL manager route to follow.

9X, Rwanda. Gordon, K7TRB, will be active as 9X0VA until October 2014. Bands and modes of activity were not provided, but he will use a Yaesu 757GX into a wire antenna. QSL via his home callsign.

VQ9, Chagos Islands (Reminder). By the time you read this, Bob, N7XR, should be active as VQ9XR from Diego Garcia (AF-006) for the next 3 weeks as of 25 August. This operation will be followed up by a 1 week trip in October or November. Activity will be focused on CW and RTTY (some SSB) during these trips. Operations will be on 160-10 meters using an IC7600 with an amp into a SteppIR-BigIR, Spiderbeam and dipoles for 80/160m. No 6 meters this trip (no antenna). QSL via NN1N, direct only (No Bureau or LoTW). Look for possible updates on

ZD8, Ascension Island (Reminder). Steve, G3ZVW, will once again be active as ZD8N from Georgetown between 21 and 29 August. Activity will be on 80 to 10 metres using CW, SSB and the Digital modes. Look for him during the evenings, early mornings, and over the weekend. QSL via his home callsign, by the Bureau or direct.


ZD9, Tristan da Cunha and Gough Islands. Paul, ZS1S (ZD9ZS), and possibly another operator will be visiting Tristan da Cunha in September/October (the ZD9 callsigns will be announced in due course). Operators will be traveling to and from Cape Town on the South African Antarctic supply ship, the "SA Agulhas II". The ship is scheduled to depart on 4 September, arrive at Tristan da Cunha four to five days later depending on the weather and sea conditions. It will depart for Gough Island after a few days and return to Tristan da Cunha ready for the scheduled departure on 4 October. The duration of the return trip to Cape Town will again be four or five days. There may be an opportunity to operate as /MM. A six meter propagation beacon, ZD9SIX, will be installed during the time on the island. The complete details will be made known in the next two weeks.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM (24 August 2014) 


PLEASE NOTE: CELL PHONE NUMBERS OF VHF/UHF AMATEURS ARE NOW “STICKY” –Many thanks to Pierre van Deventer, ZS6A, for making the above item “Sticky” at the top of the VHF Forum. This will make it easier for amateurs to access the cell numbers of over one hundred active VHF/UHF amateurs in South Africa and the neighbouring states to arrange skeds or have a chat. 

BALLOONS CARRYING AMATEUR RADIO – A simple party-style balloon carrying a 434,500 MHz solar-powered Amateur Radio transmitter is nearing the end of its trip around the Northern Hemisphere. Launched on July 12 from the UK by Leo Bodnar, M0XER, the so-called B-64 balloon is expected to complete its final transatlantic crossing over Cornwall in the UK on July 31 or August 1. It then is expected to continue east into Europe. So far the balloon has traveled some 25 000 km over 17 countries. The tiny transmitter runs just 10 mW output and weighs 11 grams. This news was reported by ARRL. In South Africa Christo Kriek, ZR6LJK, supplied more info on the proposed BACAR II balloon launching: “We have programmed our APRS trackers, please follow ZS6SRC-11 and ZS6SRC10 on 4 October 2014 from 06:00 am. Since we are launching from Vryburg there are not a lot of digipeaters/i-gates close by. We will try to have an i-gate online at the Vryburg airstrip. We also had our official start of the BACAR II program and we were surprised by the initial uptake of the schools in the area, but had to restrict attendance to 10 pupils per school and 80 attended.” BACAR II will commemorate the launch of Sputnik 1 on 4 October 1957 by attaching an active model of Sputnik to the balloon. (Read more in “BACAR II” on the VHF Forum). 

AIRCRAFT SCATTER CONTACT ON 23 cm – Etienne Swart, ZS6Y, at KG33wu informed us that he made his first Aircraft Scatter contact on 1296 MHz over the weekend. He worked Pine ZS6OB, KG44de, via Aircraft Scatter on 1296 MHz SSB with a signal report of 5/2. After hearing Pine’s CW beacon at 559 he also worked him on JT65c. His antenna was consisted of a coffee can with 10 Watts and a co-axial cable with 3 dB loss. Etienne says that he last operated on Aircraft Scatter way back in 2009 and is very rusty on that mode.    

SATELLITE NEWS – According to AMSAT – UK a team of Russian cosmonauts has deployed the Peruvian Chasqui-1 Amateur Radio CubeSat into orbit during a spacewalk from the International Space Station (ISS). Expedition 40 Flight Engineers Alexander Skvortsov and Oleg Artemyev released the tiny, 1 kg spacecraft at 14:23 UTC on August 18. Chasqui-1 is a project of the Peruvian National University of Engineering (Universidad Nacional de Ingenieria or UNI), in collaboration with the Southwestern State University in Kursk, Russia. The CubeSat’s batteries were charged last week. It was launched in February 2014 on board a Progress cargo craft. As Peru’s first satellite, its main goal is improving UNI's satellite technology, its builders said. The satellite is intended to take pictures of Earth and relay them to the ground station. It carries two cameras, one operating in the visible light spectrum and the other in the infrared spectrum. Amateur Radio is a secondary payload. Chasqui-1’s beacon on 437.025 MHz (±10 kHz Doppler shift) can transmit either 1200 bps AFSK AX.25 or 9600 bps GMSK. As of August 19, the beacon had not been heard. 

EAST LONDON / PORT ELIZABETH SKEDS ON 144,300 MHz SSB – Nightly skeds on 144,300 MHz SSB, have been restarted by Hennie Coetzer, ZS2HC, and Peter Tottle, ZS2ABF, at East London with Ken Victor, ZS2OC, in Port Elizabeth. Their first tests over the weekend were spoilt by inclement weather. Ken says he will continue the skeds nightly from Monday 1 September as weather permits. 

AN EHF CONTACT ON 134 GHz – Chris G0FDZ worked Roger G8CUB on 134 GHz over a line-of-sight path of 6,72 km in March 2014. The grid locators were JO01el and JO01fk respectively. The CW signals were RST 559 and 549. The current LOS world record stands at 114,4 km established by WA1ZMS and W4WWQ on 26 February 2006. 

LATE NEWS! “All busy running JT65c tests from KG45pu on 1296,180 MHz TX first. SSB call also welcome  – ZS6WAB”.

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.
