[Kenwood] Kenwood filter

[Tom Osborne]

Hi all
I found a Kenwood CW filter in my stuff here.  It is a International 
Radio/Fox Tango number 103 400 cycle filter.  I looked it up on the Inrad 
site and it is supposed to replace the YK-88C 500 cycle filter, which is 
what is in my radio now.

On the Inrad filter though, there are 5 holes on one side and only 3 on the 
other.  How is that supposed to fit, as there are 5 pins on each side of the 
mount for the filter.  Thanks and 73
