Hi Ron, thanks for the suggestion. Yes, I've checked the diode, it's series resistor and the capacitor - all fine. I've checked and replaced some R's that have gone high value - with no improvement. The manual suggests connecting a 8.2k R across C9 to reduce the sensitivity for alignment, and that seems to make the radio work Ok. The local oscillator waveform is not a good sine wave - is that a problem? - Dave
