ATU option now standard - you cannot buy these without ATU now as it is included as standard. 

Many radio amateurs use PC with the classical transceiver. In one case it is notebook, in other – desktop computer. Connection between those two devices is done in accordance with the User's preference. Somebody connects additional USB interfaces, somebody solder the wire harness. When there appear a question to go to contest station with the tuned working station, moving of the equipment becomes “the pain in the neck”. In such a case it is desirable to have everything in one box. SDR transceiver MB1 solves this problem by 100%.

The DUC/DDC transceiver MB1 - this is a new generation of amateur radio. Transceiver combines a classic design, accumulated many decades, with the most advanced DUC/DDC SDR-technologies - direct conversion and synthesis of radio signals, and full-featured modern computer with a CPU Intel Core i5. Operator receives a fully functional workstation in one case, which is started by pressing just a one button. All the connections can be done with a help of virtual audio cables and COM-ports, connecting the second monitor, mouse, keyboard and also to control the enjoyable radio by knobs and buttons on the transceiver's face panel.


Opportunities 

  • Uses ADC with sample rate 160 MHz and resolution 16 bit
  • Two independent receive channels with bandwidth 312 kHz
  • Record air stations with the bandwidth up to 312 kHz and an opportunity to reproduce it later
  • Opportunity to receive in Nyquist zones up to 800 MHz (necessary to set additional external filters )
  • Broad band view up to 80 MHz
  • High quality audio DAC with the precision 24 bit fro decreasing signal delays
  • Qualitative IPS 7" display with the resolution 1280x800
  • Connector for controlling external devices, 8 programmable transistor switches
  • Interface with PC – local network 100 Mbps
  • Power voltage 220V, consumption current up to 1.5 A

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.
