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.

MB1 Prime 2021, its main advantages in comparison to the previous MB1 Prime model:
1. New PC hardware:
Motherboard - GA-IMB370TN instead of MDH11HI
CPU - Intel® Core™ i7-9700 instead of Intel® Core™ i7-7700T
RAM - 16 GB DDR4 instead of 16 GB DDR3
SSD - Samsung 970 EVO 500 GB instead of generic SSD

2. Improved TX IMD3 up to ~37 dB across all HF bands, with 100W output power

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

  • 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** (SMA connector)
  • 4 separate programmable PTT outputs for external power amplifiers
  • An opportunity to use the transceiver as a signal generator via DAC OUT connector (SMA connector)
  • An opportunity to use external filters in the middle of the RF path, using RX IN and RX OUT (SMA connector)
  • Monitoring delay in CW mode is about 5-6 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 (UHF (SO-239) connector) and 2 VHF (N-type connector) 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.
