You other post you say you have 10 watts.

This is probably why you have not add an answer.
I think you need to have you power meter check as 10 watts is a lot to get from a UK FM rig even with a 1969.

Never spread any coils in any radio, it may look like you are increase power but all you are doing increases harmonic.

This is bad practice and should be stopped.

I know there are web sites, which tell you to spread coils but person how, wrote such an article had no technical knowledge of RF.
