Thanks for your reply and time. I also tried a similar experiment and found the same. There is just not enough output for the diodes to work properly. (On my TF144H/4S you have up to 2.0V to play with instead of 0.1V.) The TF1066B/1 carrier level meter uses a CS2A diode but this has more volts to play with, being connected closer to the main oscillator.

Apologies for preaching not needed, as it gives me reassurance on my own thoughts. Colin
