Many thanks to SWLing Post contributor, Mike Hansgen (K8RAT), for passing along this press release from SunSDR:

The 3B7A Saint Brandon team is now active from Saint Brandon and we are exited! This is the first major DXpedition that will be using only SDR transcievers in its setup.[…]

SunSDR2 Pro

Using past experience from their successful FT4TA expedition to Tromelin island and FT4JA Juan de Nova island Expedition, the experienced team lead by F5UFX Seb build their St Brandon setup around the SunSDR2 PRO transceiver, the SPE 1.3K-FA amplifier and ModMic attachable boom microphone.

3B7A will have 5 x HF stations on air simultaneously. Each station will have a SunSDR2 PRO with E-Coder hardware controller, an amplifier, and a ModMic. Logging is done using WinTest in network configuration and all stations will be able to operate CW, SSB or RTTY.

All 5 stations will have will have identical configuration from the keyboard to the amplifier. This will keep the operator focused on the pile-up and improve redundancy in case of any equipment failure.[…]

Note that I believe the January 2018 Bouvet Island (3YØZ) DXpedition would have also been one of the first major ham radio DXpeditions to use SDRs (FlexRadio SDRs). Sadly, due to weather and engine problems, 3Y0Z were not able to activate.
