As Alan says.
?
If the QCX has recently been built by you:
?
1. Make sure C1 is not at either maximum or minimum at the signal peak...if it is then you will need to make alterations to the input BPF ...either capacitance or inductance.
?
2. Adjustment of the three variable resistors interact with each other slightly, repeat several times to make sure you have the best results.
?
If you have a fault don't automatically assume it needs re alignment...check it through logically...altering the above may make it harder to find the fault.
