High-end SDR amateur radio
Many radio amateurs use PC with the classical transceiver. In one case it is a notebook, in other – desktop computer. A connection between those two devices every user solves according to its own preference. Somebody connects additional USB interfaces, somebody solders the wire harness. So when you want to go to the contest with the tuned working station, moving the equipment becomes “the pain in the neck”. In this case, you dream about having all that in one box and MB1 becomes a perfect solution for that.
The MB1 transceiver - is a new trend in amateur radio, a transceiver and a computer in a single package. It combines a classic design, developed over several decades, with the most advanced DUC/DDC SDR-technologies - Direct Digital Conversion (DDC) and Digital Up Conversion (DUC), plus a fully-featured high-end personal computer with an Intel Core i5 processor on board. The workstation is switched on with one button
Two independent receive channels with a bandwidth of 312 kHz
Features of the transceiver
An Independent receive path with Digital Direct Conversion (DDC)
A Separate independent transmission path, constructed on the basis of Digital Up Conversion (DUC)
Two independent receivers with panorama's bandwidths up to 312 kHz plus two sub-receivers
* Full duplex mode is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
** ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
PC capabilities of your transceiver
Installation of digital modes software
A version of ExpertSDR2 software with adapted GUI for 7" display was specially developed for the MB1 transceiver. At the present time software works in RX/TX mode and supports two independent receiving channels with the bandwidth up to 312 kHz. A DSP library developed by company Expert Electronics allowed improvement of receiving quality and higher the stability of the software.
MB1 supplied accessories
The transceiver may have an additional option: Automatic Tuner Unit (ATU) for impedance matching antennas with 50 Ohm output path of the transceiver.
Note: ATU is not installed in the transceiver in the Basic configuration
Note: ATU is installed in the transceiver in Maximum configuration
