The MB1 transceiver is a game-changer, it's a transceiver and a PC in a single package. It has a classic design, developed over several decades, with the most advanced DUC/DDC SDR technologies - Direct Down Conversion (DDC) and Direct Up Conversion (DUC) and a fully-featured high-end personal computer with an Intel Core i7 processor onboard.

The SunSDR2 DX transceiver is based on the well-known SunSDR2 PRO transceiver with several hardware improvements. It is very compact for a 100W format, has active cooling, and an improved supply system, meaning it’s perfectly suited for DXpeditions. Also, it has a separate connector for an external ATU, thus SunSDR2 DX has all the functionality you got used to in our radios and even more. Improved hardware along with the ExpertSDR2/3 software makes this high-performance SDR transceiver the perfect base station. The evident choice for a true contester!
