Hi Andrew, and welcome to the forum. I too have a Signal R535 and it does look like you are receiving an image from the FM broadcast band. Assuming the IF is 10.7MHz (I can't be sure without looking at the circuit diagram) and you are monitoring Newcastle on 124.375, this should give a local oscillator frequency of 113.675MHz (124.375MHz-10.7MHz). If you have another receiver such as a scanner, try tuning it to this frequency, and if the local oscillator PLL is locked and functioning correctly, it should be possible to pick this up if held near the R535. If not there is something wrong with the oscillator.
Alan.
