Description

Many radio amateurs use PC with a classical transceiver. In one case it is a notebook, in other – a desktop computer. A connection between those two devices every user solves according to its own preference. The perfect solution is MB1!

The MB1 transceiver - is a new trend in amateur radio, a transceiver and a PC 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 onboard. The workstation is switched on with one button.

• Two independent receive channels with a bandwidth of 312 kHz
• Broadband overview of up to 80 MHz
• High-quality IPS 7" touchscreen display with a resolution of 1280x800 pixels
• ExpertSDR2 software in two versions: for Desktop and for integrated GUI display
• Opportunity to install any other software (applicable for Windows 10 OS) by the User
• Record and play on air fragments (IQ files) with a bandwidth of up to 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)
• Full duplex or half-duplex modes*
• Two independent receivers with panoramic bandwidths up to 312 kHz plus two sub-receivers
• 4 HF antenna connectors and 2 VHF
• Four separate programmable PTT outputs for external power amplifiers
• ALC connector for external power amplifiers**
• The ability to connect VHF transverters
• The ability to use the transceiver as a frequency measuring receiver
• The ability to use the transceiver as a signal generator (DAC OUT)
• A minor delay in CW mode (about 10 ms)
• Ability to use the transceiver in SO2R mode
• Remote control mode

* 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.
