Amazing what you learn here, innit?
After all these years of fiddling around with various comms. receivers, I've never heard of a 'PTR' receiver, let alone as a variant to the PCR. I've always been led to believe that the abbreviation 'PCR' stood for 'Personal Communications Receiver'. On that basis, anyone know what the abbreviation 'PTR' stood for?Al.
