In this video I’m taking a more detailed overview, showing some of the features it will do, and my overall opinion about what I think about it.
Expert Electronics MB1 PRIME (2021 Version)
The MB1 PRIME 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 i7 processor onboard.
The main advantage of the MB1 PRIME 2021 over its predecessor has improved TX IMD3 AND all-new PC hardware:
- GIGABYTE GA-IMB370TN Industrial ITX Motherboard
- Intel Core i7-9700 3.00GHz 8-Core/8-Thread CPU (4.70GHz Turbo Freq)
- 16GB DDR4 RAM
- Samsung 970 EVO 500GB SSD (Solid State Drive)

- 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
- Full-function radio amateur transceiver
- Mobile contest-station
- Remote receipt point for the contests and other applications
- Spectrum analyzer with the bandwidth up to 80MHz
- Work with the external programs of digital connection types, CW Skimmer, etc.
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.
