via the RSGB: 6 December 2021 – Using the Pluto and RPi4 for Amateur TV and Narrowband use by Noel Matthews, G8GTZ

Following on from his talk Advances in Amateur Television at the RSGB 2016 convention, Noel Matthews, G8GTZ presents the latest developments in the ever-evolving world of amateur TV.

Noel gives an overview of ATV activity in the UK and in particular how the use of reduced bandwidth (RBTV) signals enabled ATV QSOs on the lower VHF bands.

He gives an introduction to the QO100 geostationary satellite which has enabled QSOs with fellow DATV operators as far away as Brazil, India and South Africa.

Noel also describes how the development of software-defined radio (SDR) based hardware and powerful single board computers such as the Raspberry Pi has revolutionised the development and capabilities of amateur radio dedicated products.

He describes how it is possible for radio amateurs to build an advanced touch screen multimode narrowband and digital ATV transceiver covering 50 MHz to 10GHz, for under £350.
