Did you check the front end for tin whiskers like someone else posted? They 
can easily destroy sensitivity.

Hi Jim,  I am using a Wavetek 3001. I also have a MVP here with the same 
helical filter and it doesn't exhibit this.  Hence fairly convinced that 
something is going on with the Exec's filter.  It seems like the signal is 
getting better because were loosing the loss of the filter stage.  Update 
now is that I have resoldered the base of the first coil and ant connections 
and it has got a lot better. I don't see the change near as much, but moving 
the cable around still does impact the signal.. The RX freq is 448.625 and 
sensitivity seems to be .72uV for 20db of quieting versus spec of .5uV.  So 
still fighting it.
