Default Re: No LW/MW receive - Sony ST-S311

oh, well, it seems the signal I was tracing through the IF and onwards was in fact just the IF oscillator! Turning the modulation on and off made not the slightest difference to the signal on the IF! So whats coming out, distorted, from the AM subsystem IC is just a badly distorted IF oscillator signal!
