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.
