Information on equipment & support that is available on the DXpeditions in Africa

Daniel ZS6JR is tasked with the technical portfolio.

CQ-DX African Safaris offers a number of packages…..single operator single tx, multi-op single tx or multi-op multi tx.

Radios that can be used include:-

  • Elecraft K3
  • Yaesu FT1000MP
  • Kenwood TS850
  • Icom IC765.

Amplifiers that can be used are:-

  • Icom IC2KL
  • Kenwood TL922
  • Tokyo HL1K.

For the multi-tx dxpeditions Dunestar and ICE band pass filters can be used together with stubs.

CQ-DX African Safaris has 2 portable trailer towers that are used to support the antennas.

There are several choices of antennas.

  • Cushcraft A4S,
  • A3S tribanders,
  • A3WS warc duo-bander,
  • Tennadyne T8 lp and a Minibeam 2 ele for 17 and 12m.
  • A 2 ele wire beam,
  • 10m long vertical with elevated radials and a wire 4 square is available for use on 40m.

A 20m long aluminium mast is used for 30, 80 and 160m. Switching is done remotely via the coax cable and either 20 or 40m long radials are run along the ground, location dependant.

On arrival Daniel ZS6JR will assemble the tower and antennas as well as the station configuration with help from the customer concerned.
Time taken is 1 day and perhaps another morning dependant on the specific requirements.

Swaziland already has a permanent tower installed and has a Cushcraft A4S at 24m, an A3WS at 20m as well as a wire 40m 4 square around the tower. Thus minimal installation time at this destination. A small selection of tools and spares are taken along to enable running repairs to be undertaken.

Daniel ZS6JR will be on hand to affect such repairs. Operators are requested to bring along their own preferred headset, footswitch and key, as well as a suitable laptop and logging software and necessary connecting cables and connectors to attach to the chosen radio..

  • Elecraft K3

CQ-DX African Safaris is pleased to announce that we are able to offer 2 Elecraft K3 radios to the multi-operator dxpeditions. The older Yaesu FT1000MP’s have offered fine service over the last 4 years….however, apart from the better dynamic range the Elecraft K3’s offer lower phase noise characteristics, relay switched front-end filters resulting in better receive immunity to intermod especially in the closer station proximity found in dxpeditions and better DSP functionality. They are also smaller and lighter than the older radios. With the improvement in the solar conditions the radio will also permit operation on the 6m band, a feature the Yaesu’s did not have.

The K3’s are fitted with 8 pole 2.8 kHz 8 ssb and 400hz cw filters. I am particularly pleased with the announcement and look forward to the next big group to put the radios to the test……..73 Daniel ZS6JR
