General description of radio:
Designed in Russia. Assembled in Taiwan (R.O.C)
Many radio amateurs use PC with the classic analog transceiver. Connection between computer and radio requires USB cable and other interfaces . SDR MB1 transceiver elegantly solves connections problem. No more wires!
The HF, 6m and 2m DUC/DDC transceiver MB1 - is a new generation of amateur radio. Transceiver combines a classic design, accumulated over many decades, with the most advanced DUC/DDC SDR-technologies - direct conversion and synthesis of radio signals, and full-featured modern computer with a Intel Core i5 CPU. Operator receives a fully functional workstation in one box, which is started by pressing just one button. All the peripherals connections are internal with virtual audio cables and COM ports; Simply connect second monitor, mouse, keyboard and you may control SDR radio with knobs and buttons from the transceiver's front panel.

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 Expert Electronics allow to improve receiving quality and increase stability of the software. Supported OS: Windows 7/8/10.
MB1 set includes:
- MB1 transceiver + ATU
Note: internal Automatic Tuner Unit is installed in the transceiver
- Power supply cable for connecting the transceiver to AC mains
- Two audio adapters JACK 6.3 mm to JACK 3.5 mm for connecting the headset to the transceiver
- Latest version of Software is available at the Expert Electronics website
