Looking for one..

Kenwood TS-430S optional filter YK-88A (AM 6KHz bandwidth)

Need for shut-in listening to SW broadcasts and the occasional AM
ham transmission.

The standard Kenwood AM filter is really the SSB filter which is
too narrow for AM BC SWL.

I realize this is an old part (1986), but maybe there is one out
there in a '430 that is only used for listening to SSB or CW (AM
TX does not require this filter, it's only used for wideband RX),
or maybe a junker TS-430S available I can rob one from.

Filter is plainly labeled and can be seen by removing the top of
the radio. May be marked "Trio" or "Kenwood" and will be marked
"AM FILTER YK-88A".

center frequency = 8831.5 KHz
passband = 6KHz @ -6dB
attenuation bandwidth = 11KHz 60dB

Thank you, any help would be appreciated, Please decode my e-mail
address below by removing spaces and subtituting @ for AT and .
for DOT (sorry spam is a real issue.)

These guys do nice work. I will suggest getting an 8 KC filter instead of
the 6 KC one, though. Noisier, but better-sounding.

I have a 4kHz one in my R5000 (compatible with the TS-430). I prefer that to
the Kenwood high qaulity 6kHz one.

My 430 has the filter so I can't test it, but if you look on the mods pages
you find a way of twisting knobs to get it to work without a filter.

You could also try the ts-430 yahoo group.
