I have a WJ-8716 with the  optional preselector.

With the preselector, intermod from local broadcast  stations is not a 
problem.

Compared to a 390A, the crystal filters in the  8716 are brick-wall type 
things.

Sensitivity of the 8716 is superior to  everything else I own.  


Hi Tim,
My impression of the crystal filters in the WJ 8716/8718 is the shape  factor 
is rather sloppy on the
3.2KHz 'AM Narrow' filter and the .3KHz 'CW Narrow' filter. The 3.2KHz  
filter is a 10.7MHz CF filter and sounds more like a 4 + KHz wide filter in my  
radio. The .3KHz CW filter is a 455KHz CF filter and sounds more like   600-700Hz 
wide  to my ears. The USB/LSB filters sound excellent in the WJ  though.
 
Those are my only complaints about the radio. Otherwise sensitivity,  
stability, readout etc. are excellent.
 
The 455KHz mechanical filters in the R-390A sound far superior in  shape 
factor to my ears compared to the 10.7MHz crystal filters used in the WJ  
8716/8718.
