High-end SDR amateur radio
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.
Intel Core i7 6700T
Features of the transceiver
An Independent receive path with Digital Direct Conversion (DDC)
A separate independent transmit path, constructed on the basis of Direct Up Conversion (DUC)
* Full duplex mode is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the next ExpertSDR2 1.3 software release.
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
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.
