Patrick,

Check that R2 is definitely 220R. This is in the path of the FM MPX signal


I am just about to check all that you suggest, but have noticed that the above contradicts the tuner instructions that give R2 as the 22K resistor (R13 is the 220). Is this just a typo above or is this the problem?

Paul,

I would say that we have the same problem - quiet, poor reception more like a distorted signal rather than just a weak one. I don't know if mine clicks when changing frequency as I tuned it in to known stations on the bench before I had any speakers connected and have left it tuned in ever since.
