MB1 High End HF, 6m & 2m SDR Transceiver

MB1 is a modern, high performance direct conversion SDR transceiver with a classic design for HF, 6 meter bands and 2 meter bands. It has an Intel Core i5 PC onboard making it a fully functional workstation in a single physical unit. No more hassle with cables between you high performance SDR and computer, all connections are done internally using virtual audio cables and virtual COM ports. The MB1 is the future of ham radio.
