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) 


AMATEUR RADIO TO CIRCLE THE MOON – A lunar flyby with a ham radio payload transmitting JT65B mode on 145,990 MHz is expected to take place toward the end of this year, giving earthbound radio amateurs the opportunity to receive some otherworldly DX signals as the payload flies around the Moon. China has announced plans to launch a lunar orbiter carrying a 14 kg battery-powered payload known as 4M-LXS, which was developed at LuxSpace. Signals from the Amateur Radio payload can be decoded using the free WJST software by Joe Taylor, K1JT. The orbiter is one of the test models for Beijing’s new lunar probe Chang’e-5, which will land on the moon, collect samples, and return to Earth. The launch, planned for 4th quarter 2014, is aimed at testing technologies that are vital for the success of the spacecraft. The orbiter will be launched into Lunar Transfer Orbit and then perform a lunar flyby before re-entering Earth’s atmosphere after 9 days. The orbiter, which arrived by air in Xichang, Sichuan, on Sunday, August 10, has been transported to the Xichang Satellite Launch Center. — Thanks to AMSAT-UK 

UHF NEWS FROM DIVISION 3 – Charl Krapohl, ZS3K, describes their 70 cm skeds between Strydenburg and Bloemfontein over a distance of 266 km. He says: “Me and ZS4PV are running a sked on 432,200 MHz at 20:15 CAT on Mondays. Work and other commitments keep us from more regular skeds. Equipment: ZS3K – 25 Watts no preamp, heliax feeder and 15 element NBS Yagi 14 metres high. ZS4PV – 80 Watts with preamp, heliax feeder and I think 17 element NBS Yagi 8 metres high. Results: There are not so many openings with good propagation at the moment, but I can sent you the dates we had good openings with S9 signals. We kept a sked going for a few years on 2m on same path and it seemed that it was possible to communicate with above average signals most of the time with10 Watts and single Yagis. If you need more info I would gladly provide it.” 

Z21EME DX-PEDITION PLANNED – There will be a multiband VHF station operational from Zimbabwe from the 1st November to the 7th November 2014 by John Sygo ZS6JON / Z21EME. He says: “We will be operating on the following frequencies. 50 MHz 11 element M2 Yagi – 144 MHz 4 x 9 element Hor & 4 x 6 element Ver Yagi's – 432 MHz 1 x 38 element M2 Yagi – 1296 MHz 1 x 67 element Wimo Yagi. We will be primarily concentrating on EME but when there is no Moon we would be available for local contacts back to SA. Our location is 70 km into Zimbabwe and 550 km from Johannesburg. Grid: KG58fg. We should have Internet to be able to make skeds. HF may also be possible, to be announced at a later stage. You have two months to get you antennas ready. Hope to hear you.......73 John & the Z21 Team.” 

MICROWAVE TESTS BETWEEN DIVISIONS 2 & 6 – Etienne Swart, ZS6Y, has informed us that he acquired a 1,2 metre dish with a gain of 22 dB for his 1,3 GHz equipment. He is planning to run skeds with Alex Gogos, ZR2T, of Port Elizabeth at the end of the year or early next year, and who is now the proud owner of a 4 metre dish. The idea is to operate from a high site at each end when Tropo Ducting is possible, and establish new records. The current IARU Region 1 record for Tropo on this band stands at 2651 km established on 10-07-2010 by D44TXV and CT1HZE. 

NEW ACTIVITY ON 70 MHz (4 METRES) – Ian Roberts, ZS6BTE, from KG33xv reported 70 MHz two-way contacts on Saturday afternoon 17 August at 15:30 CAT. He worked Willem ZS6WAB on 70,02502 MHz over a distance of 291 km with signals varying with QSB from S1 to S7 via Tropo Scatter. This was followed by a local contact with John ZS6JON at S7 on a frequency of 70,00977 MHz. He is using a 7 element high gain Yagi on this band and a MOSFET front end to a transverter with output on 28 MHz. 


FM ON 1296,250 MHz – Willem ZS6WAB conducted tests on 1296,250 MHz FM during the week from KG45pu, but we have not heard about his results. He also intended to run his normal skeds on Saturday morning on 1296,200 MHz SSB.

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.
