Hi

Please disregard the info I gave in the previous post regarding the tuning capacitor, I've confused myself over the required value which should be 2 to 10pF according to the circuit diagram. I am not sure how this can be achieved with the supplied cap, not to mention stray capacitance as well. I may use an air-spaced Jackson type for initial tests.

Regards
Symon

EDIT: Maybe the trimmer caps on the tuning cap may be the answer. I'll have a look tomorrow. S
