MB1 transceiver - is a new trend in amateur radio. This is a transceiver and a computer in a single package. It combines a classic design, developed for several decades, with the most advanced DUC/DDC SDR-technologies - Direct Digital Conversion (DDC) and Digital Up Conversion (DUC), and full-featured modern personal computer with an Intel Core i5 processor on board.
The operator gets a full-featured workstation in a single package, which can be switched on by pressing one button.
Two independent receive channels with bandwidth 312 kHz
Features of the transceiver
Independent receive path with Digital Direct Conversion (DDC)
* Full-duplex mode is supported by the transceiver's hardware, but is not implemented in the firmware and software yet. This mode will be implemented in future versions of ExpertSDR2 software
PC capabilities of your transceiver
Installing of digital modes software
Internal PC's parameters
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 to improve receiving quality and higher the stability of the software. Two OS are supported: Windows 8 and Linux Ubuntu.
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
Dynamic microphone MD15
Note: ATU is installed in the transceiver
