The Minima transceiver
19 January 2015 | by See http://www.phonestack.com/farhan/minima.html
This is the latest project from Ashaar Farhan. Component cost is said to be less than $100. This is based around a Si570 sythesiser and a programmed Arduino micro-controller IC. It looks a simple to duplicate rig covering up to 30MHz. It is the successor to the BITX rig I think. The IF is 20MHz. If you only want 0-15MHz or 15-30MHz (i.e. not both) the rig get even simpler.
As it stands it produces 1W pep but it is easy to add a further PA.
Although a kit of parts is available, I am not aware of a full kit with enclosure and a PCB being available as is the case with the BitX from Hendricks Kits.

I am trying to build Minima transceiver. I have Arduino, digital dial/LCD and do have Si570 but I don’t know the step by step programming etc. My desire is to make this digital control device but I can’t find anyone to guide me from the start.
Also I have DDS kit but the hookup would be a challenge because Chinese made DDS doesn’t have good instructions. They
just sell the unit. If you could please help. I live in Dallas, Texas USA. My email is [email protected].
Thank you,
