DXpedition to Kiritimati (Christmas Island)

28 September to 26 October 2011


T32C Equipment

Yet again FSDXA are proud to have the sponsorship and support of Yaesu.  All FSDXA DXpeditions to date have been powered by Yaesu transceivers and amplifiers.  As you will have read elsewhere on the site, the original plan was to use 16 FT DX 5000 transcevers with 16 VL-1000 linear amplifiers - however these remained in a sea container at Tarawa during the DXpedition.  At very short notice Yaesu offered the use of 10 FT-450D transceivers so that the DXpedition could continue - these were used with a variety of ACOM, Expert, Tokyo and home built linear amplifers, all of which were hand carried to the Island.  Usually there were 9 stations operational, some of which were reconfigured between low and high band operation depending on the time of day.

10 X FT-450D HF/50MHz 100 Watt transceivers

The FT-450D is a compact yet superb HF/50MHz radio with state-of-the-art IF DSP technology configured to provide World Class performance in an easy to operate package. Suitable for all applications; beginners, casual operators, enthusiasts, portable/field users and emergency service providers

The DXpedition used primarily vertical antennas constructed using fibreglass poles and positioned at or close to the high water line on a North facing beach.

160m - 18m tall T antenna with 32 radials
80m   - Quarter wave vertical with 32 radials
40m   - Quarter wave vertical with 2 elevated radials. A reflector was added mid DXpedition
30m   - Quarter wave vertical with 2 elevated radials
20m   - 2 off 2 element vertical dipole arrays
18m   - 2 phased 2 element vertical dipole arrays
15m   - 2 off 2 element vertical dipole arrays
12m   - 2 element vertical dipole array
10m   - 2 element vertical dipole array and dipole at 50 ft
6m     - 8 element 6M8GJ M2 Yagi
