More info

The MB1 transceiver is a game changer, it's a transceiver and a PC in a single package. It has a classic design, developed over several decades, with the most advanced DUC/DDC SDR technologies - Direct Down Conversion (DDC) and Direct Up Conversion (DUC) and a fully featured high-end personal computer with an Intel Core i5 processor on board.

Features of the transceiver

  • Independent RX path based on DDC (Direct Down-Conversion) architecture
  • Independent TX path based on DUC (Direct Up-Conversion) architecture
  • 2 software RXs + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz
  • ExpertSDR2 software in two styles: Desktop style and MB1 display (for integrated GUI)
  • Remote control operation, using it, you connect PTT and CW-key to the E-Coder panel. Microphone and E-Coder are connected to the remotely set up PC
  • TCI interface for seamless connection with third-party software like SDC (with its own Skimmer), LogHXSWISSLOG and RUMlog, more are coming
  • Professional TX processing module provides the most advanced tuning capability for voice operation
  • High-quality IPS 7" touchscreen display with a 1280x800 resolution
  • Supports any software applicable for Windows 10 OS
  • ExtCtrl connector to control external devices with 8 powerful keys with open collector
  • COM-port for connection of external devices, like PA, antenna switches etc.
  • ALC connector for external power amplifiers*
  • Has a special XVTR connector for VHF transverters**
  • 4 separate programmable PTT outputs for external power amplifiers
  • An opportunity to use the transceiver as a signal generator via DAC OUT connector
  • An opportunity to use external filters in the middle of the RF path, using RX IN and RX OUT
  • Small delay in CW mode (about 10 ms)
  • Input for external 10 MHz reference oscillator
  • An opportunity to use the transceiver in SO2V mode
  • Full duplex or half duplex modes***
  • 4 HF and 2 VHF antenna connectors
  • Internal power-meter for HF and VHF bands and SWR-meter for HF band
  • Record and play on air fragments (IQ files) with a bandwidth of up to 312 kHz
  • Internal ATU (Automatic Tuner Unit)
  • The embedded power supply unit

* ** *** These functions are supported by the transceiver's hardware, but is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.

 

PC capabilities of the transceiver

  • Installation of digital modes software

  • Installation of HAM and Contest logs

  • Two CW Skimmers may be used on different bands

  • The transceiver can connect to the LAN and the Internet

  • Use of Internet applications (e.g. e-mail, Skype, ICQ, TV, etc.)

  • Play video and audio files

  • Watch TV via USB-receivers

  • An opportunity to connect two external displays, keyboard, mouse

  • An opportunity to connect external speakers to the PHONES jack on the front panel

 

Application area

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+ATU supplied accessories

  • PTT-microphone MD15
  • Power Supply Cable to connect the transceiver to an AC mains network
  • Backup fuse 5A

Additional accessories:

  • E-Coder control panel for comfortable remote operation
  • HPF for VHF
