Hi Mike

Don,W3FPR just gave you very good tips to look at your problem.
Another one may be the BFO frequency not in place in respect of the filter 
bandpass.
Look in the technical part of the filter alignment and see if your BFO 
frequency follow (at some 10th of Hz) the values given in the book.
If you are in CW (normal) and if the BFO is on the other side of the 
bandpass you will not hear anything !!!
Good luck Mike in your hunting! 73
