Cannot find peak bpf on qcx #alignment #40m

Hi all.

I have a problem with my QCX where I can't find the peak BPF at all when i'm turning the trimmer capacitor. All it does is switch back and forth from 1 to 2. I have nothing connected to the antenna port. I have noticed that if I press down on the trimmer screw it will sometimes jump and get a good peak. What do I need to do?

Thanks, Hawth
