This "Prime" model - the latest development of Expert Electronics is an alternative version and will be available with the MB-1.

The features of this release include the following differences:

- CPU - i7 instead of i5

- RAM - 16 GB instead of 8 GB

- SSD - 525 GB instead of 120 GB


The MB1 DUC / DDC transceiver is a new generation of radio amateurs. The transceiver combines classic design and accumulated many decades with the most advanced DDC / SDR technology - DUC direct conversion and synthesis of radio signals and the complete modern computer with an Intel Core i5 processor. The operator receives a fully functional workstation in one case, which is started by simply pressing a button. All connections can be made with the help of virtual audio cables and COM ports, the connection of the second monitor, mouse, keyboard, and also to control the radio from buttons and push buttons on the front panel of the transceiver.


Many radio amateurs use their PC with the common transceiver. The connection between the two devices is done according to the user's preferences. Someone connects additional USB interfaces, wiring some solder. When there seems to be a question to go to the contest station with the tuned workstation, moving equipment becomes a big deal. In that case it is desirable to have everything in a compact box.The SDR MB1 resolves this problem a lot of trouble!


ATU to Part
