[Kenwood] Knwd filter question

[Rick May]

Hello,

    The YG-88X filters are larger than YK-88X filters because they are 
discrete 8 pole crystal filters while the YK-88X are monolithic (Some 
say equivalent to a 6 pole others say only a 4 pole discrete crystal).  
You will notice that the word 'Crystal' does not appear on the YK-88X 
filters.  The YG prefix is used on the 455 'CRYSTAL'  filters.. I use a 
YG-88S filter filter in one of my TS-830's and there is a noticable 
improvement over the stock YK-88S. They are both 2.4 khz filters. The YG 
is much too large to simply solder in so I had to use RG-174 and .01uF 
decoupling caps.  Same center frequency.
