Features

The whole station in one case

Usually a computer sits next to the transceiver, with USB interfaces and cable looms in between. In the MB1 the links are virtual audio cables and COM ports, and you take one unit to the contest station.

A new-generation computer

  • Intel Core i7-9700 processor, GA-IMB370TN motherboard.
  • 16 GB DDR4 and a Samsung 970 EVO 500 GB SSD.
  • Any Windows software: digital modes, logs, two CW skimmers on the two receivers.

The transceiver

  • Separate paths: direct sampling on receive (DDC) and direct digital synthesis on transmit (DUC).
  • Two independent receivers with panoramas up to 312 kHz and a sub-receiver each, a band scope up to 80 MHz.
  • Transmit IMD3 around 37 dB on HF at 100 W, CW sidetone latency of 5–6 ms.
  • Built-in power and SWR meters, an optional automatic tuner, four programmable PTT outputs.

Use Cases

  • 01

    Main station

    A full-featured transceiver without a separate PC.

  • 02

    Mobile contest

    One unit instead of a transceiver, a laptop and a cable loom.

  • 03

    Remote receive site

    For contests and more, through ERS.

  • 04

    Spectrum analyser

    Up to 80 MHz of spectrum at a glance.

ExpertSDR3, TCI and ERS

Free ExpertSDR3 with free updates. The open TCI protocol connects loggers, skimmers and digital-mode programs without virtual COM ports or audio cables; programs without TCI use the RadioSync bridge (CAT, OmniRig). Expert Remote System (ERS) is included: control from a browser or ExpertSDR3, directly or through the ExpertCloud service.

About the software
  • ExpertSDR3Free software for operating on the air
  • TCIAn open protocol for loggers, skimmers and digital modes
  • ERSRemote operation from a browser or ExpertSDR3

Hardware headroom

  • ALC*

    Input for external power amplifiers.

  • XVTR*

    VHF transverter connection (SMA).

  • Full Duplex*

    Full-duplex operation.

* The hardware supports these functions; software support comes in ExpertSDR3 updates.
