MiniTiouner hardware Version 2

The Minitiouner hardware is designed for easy home construction, uses only leaded components and consists of the 3 main components.

Whilst the project had previously used several tuner types and a version 1 PCB and adapter cards, new builders should only use the Serit tuner and version 2 PCB described on this page.

To build the unit you only need to buy the following and then download the free MiniTioune software.

• The USB interface is available ready programmed from the MiniTiouner category in the BATC shop.

• The version 2 main PCB can be bought from the BATC shop.

• The tuner or NIM. The Serit tuner covering 143 - 2450 MHz is available from the BATC shop

• The unit uses an MCP1826 1v regulator, which can be hard to find and is available from the BATC shop.

All other components such as Rs and Cs are available from normal suppliers.

MiniTiouner Version 2 PCB

As from April 2017 ONLY the version 2 PCB designed by Mike G0MJW is available from the BATC - new builders should use this version which takes the wide coverage Serit Tuner enabling coverage from 140 - 2500 MHz without any external upconverters.
