Sounds like you might have a bad hetrodyne crystal on 40 meters.  If you 
have a general coverage receiver tune it to the oscillator frequency and see 
if you hear a strong carrier when you move the antenna near the crystals on 
the filter board.  If not you may have a bad crystal or a bad solder 
connection on the relays that switch then in and out. Next look at the 
solder connections on the filter board very closely.
