Using the Pluto and RPi4 for Amateur TV and narrowband  –  Noel G8GTZ.

Following on from his “Advances in Amateur Television” talk at the 2017 RSGB convention, Noel Matthews, G8GTZ will be presenting on the latest developments in the ever-evolving world of Amateur TV.

Noel will give an overview of ATV activity in the UK and in particular how the use of Reduced bandwidth (RBTV) signals has enabled ATV QSOs on the lower VHF bands. He will give 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 will also be describing 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 will describe 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.

=========================

All you need to get started in Software construction is a personal computer (Windows, Linux, Mac – they’ll all do), some spare time and, if you want to make a ‘thing’ then some loose change.

There are three easy and virtually free routes into writing your own programs: develop applications that run on your PC using the free Qt environment; write programs to run on one of the Arduino boards (£3 from China plus a USB cable) using the free Arduino application; or go for the middle ground with a Raspberry PI (around £40) and a wi-fi connection.

Heather will take you through the setup for each of these and show you just how easy it is to go from flashing an LED through developing an ATV receiver to producing a fully-featured windows PC application such as her Mapper entry in the RSGB construction competition.
