这是一个开放参与的项目（但没有完全开源）。这种项目组织方式+牛逼的技术背景，产生了优秀的产品。该机构架为前级+SDR收发机+PC机构架（据说是I7的电脑），售价约3K欧元，低于目前同类产品。传统厂商有些招架不住啊。

Special for SunSDR-MB1 will be developed an ExpertSDR2 software version with adapted GUI.
Features of the software is very big. You can find it in user manual which will be released in end of this month.

Approximately price on first model SunSDR-MB1 in base variant: 150 000 RUB ~ 4300 USD, + option ATU 6000 RUB ~ 200 USD
Exact price will be known after finishing all works with the first preserial model, which you seen in video(a small part - front panel).
Also may be will be started a special offer with prepayment with discount ~20% for first buyers... will seen after HAM Radio 2014 at Friederichshafen in Germany.
Approximately date of starting sales - end of autumn.

The picture with back panel has some difference with the first serial model of SunSDR-MB1 transceiver.












At the present time we are working on new GUI for SunSDR-MB1. Usual an ExpertSDR2 GUI was changed to special GUI for monoblock. Half way already passed. Next step it is increasing a fonts on the frequency scale between spectrum and waterfall, and increasing fonts on PWR-meter, SWR-meter and MIC-meter. Touch panel installed on high resolution IPS 7" display, and gives to user possibility to choose any function or to set any frequency in one touch.
On next week I'll publish a new photo with a fully assembled SunSDR-MB1 and finished GUI.


Today was the first start of GUI for SunSDR-MB1.
