MB1 SDR Transceiver

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

• Broadband overview of up to 80 MHz
• High quality IPS 7" display with resolution 1280x800
• ExpertSDR2 software in two versions: for Desktop and for integrated display GUI
• Opportunity to install any other software (applicable for Windows 10 OS) by the User
• Record air fragments (IQ files) with bandwidth up to 312 kHz and an opportunity to play it later
  
  

Features of the transceiver

• Independent receive path with Digital Direct Conversion (DDC)

• Separate independent transmission path, constructed on the basis of Digital Up Conversion (DUC)
• Full duplex or half duplex modes*
• Two independent receivers with panorama's bandwidth up to 312 kHz and two sub-receivers in each of them
• 4 HF antenna connectors and 2 VHF
• Four programmable PTT output for external power amplifiers
• Ability to connect the VHF transverters
• Using the transceiver as a measuring receiver
• Using the transceiver as a generator (DAC OUT)
• Minor manipulation delay in CW mode (about 10 ms)
• Ability to work with the transceiver in SO2R mode
• Remote control mode

* 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

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 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.
