MiniTioune

MiniTioune is a USB connected hardware project for receiving digital TV transmissions on the amateur radio or broadcast bands. When used with the Tutuione DVB-S receive and analysis software from F6DZP it can be used to receive DVB-S QPSK transmission from broadcast and amateur TV transmissions with symbol rates (SR) from 30 Msymbols down to 112Ksymbols per second.

The very wide symbol rate range means it is capable of receiving all amateur TV transmissions, including the Reduced Bandwidth (RB-TV) transmission below 1 Msymbol and the HamTV signals from the ISS. It can also be used to receive domestic sateliite transmissions. Whilst the hardware is capable of recieving DVB-S2, the Minitioune system currently only receives DVB-S QPSK transmissions, but may receive other modes in the future with further PC software development.

When used with the Sharp or Samsung tuner or NIM component, frequency coverage is from 650 MHz through to 2600 MHz. This extended frequency coverage gives greater flexibility when working with upconverters from the VHF bands and enables the 10 GHz band, including eshailsat down link, to be received on a standard domestic PLL LNB.

Hardware

The hardware consists of 3 major components – the Tuner or NIM, the USB interface and power supply components.

The extended range Sharp tuner and pre-programmed USB interface module and a blank PCB are available from the BATC on line shop https://batc.org.uk/shop/hardware-and-kits – all other components are available from normal suppliers.
