[Kenwood] Heath CW filter in a TS-520S

[Rob Frohne]

Hi All,

I looked at the schematic and it appears that the Heathkit CW filter I 
had kicking around would work in the old TS-520S that I recently picked 
up.  The termination impedances look the same and the frequencies are 
the same if I can believe ICM's web site.  I tried it and it has about 
30 db loss.  I kind of think that the filter has something wrong with 
it, but I'm not sure.  Does anyone else have any experience with this 
substitution?

73,
