The aim of this demonstration is to give an insight into the need for alignment of radios or TVs and to show how to align a typical radio. I’ll also briefly mention TV alignment and demonstrate the use of a signal generator with a wobbulator function and, if time permits, the use of a spectrum analyser. I’ll be using the following equipment Philips PM5324 RF signal generator Trio CS5270 100MHz oscilloscope HP8558 Spectrum Analyser Black Star Meteor 600 Frequency counter Demonstration board with two tuned circuits Battery valve radio Vidor CN435Z Jasonkits AM/FM tuner Test loop Why do we need alignment?
