Thanks to everyone who is helping to follow up this topic .
I have received information from SM2EKM; K3MM; K0ZZ; G3XSV; N7RT among
others ! I will get as much information together and post it here as
soon as possible. 
Any more info regarding Pin diode and 2nd order or is it 3rd (!?)IMD
greatly appreciated.

This is a great system for useful information dissemination .....!
