FO&A,

Has anyone tried the Kenwood YK-88S1 or YK88S2 in a Kenwood R-5000 ?

The normal IF Filters used in the Kenwood R-5000 are the
'stock' YK-88S (2.4 kHz) Wide SSB Filter and the 'optional'
YK-88SN (1.8 kHz) Narrow SSB Filter.

However there seems to be two other Kenwood SSB Filters
that 'appear' to be Drop-In-and-Solder (Size and Wiring)
of the Kenwood R-5000 ? {Now is that True}

* Kenwood YK-88S1 (2.6 kHz)
- Wide SSB IF Filter

* Kenwood YK-88S2 (3.0 kHz)
- Very Wide SSB IF Filter
- Very Narrow AM/MW IF Filter

Any Comments & Opinions ?

I don't know about those, but when I had an R-5000 I put a better 6kHz filter in
it. The stock filter had pretty broad skirts.
