[crackle]

I am thinking there may have been a fault with the original red CT2 trimmer cap. I was trying to test it to measure the value and could not get a steady reading.
Anyway I have taken a green trimmer from an old chassis and fitted that.
The frequency can now be set precisely to the correct value for the channel, so all good there.
The signal on my adjacent radio is now a lot stronger, with no aerial plugged in before it was reading S9 it is now reading S30.
Just need someone now to pop up on the band so I can give the radio a final check for quality.

Thanks for your advice and help, I know a bit more about the process of Delta Tune now.
