3B7A DXpedition | Equipment

Equipment

We’ll have at our disposal 5 x HF stations. Each one  will have an amplifier and will be able to communicate in the 3 different modes (CW, SSB, RTTY). Logging software will be Win-Test.

In order to maximize the configuration of the location and more specifically the proximity of the ocean we intend to use monoband vertical antennas as well as VDA that have proven to give excellent results during top DXpeditions in the past few years. This type of antennas are quick to setup even by windy conditions and fits perfectly with the restrictions we have.

All 5 stations will have the same equipment (from the keyboard to the amplifier). It will be much easier to replace any part in case of failure. We want also to have the operator focused on the pile-up, not on trying to get familiar with unfamiliar rig or amplifier.
