Hi.

Sure enough, by carefully adjusting the two trimmers on the tuning cap to near minimum, the tuning cap swing is approximately 2 to 12pF which I'll settle for. The tuning coil will be 'adjustable' by compressing or expanding it slightly to attain the correct frequency coverage. I suppose I could try using the GDO to assess the coverage.

I'll report back when further progress is being made.

Regards
Symon.
