Let's say you want to add the following filters to the R-5000:

YK-88SN Narrow Sideband

YK-88C 500 Hz CW

YK-88CN 250 Hz CW

YK-88A1 AM Filter

Where would you install the 88C and 88 CN, as the instruction manual
shows the installation of EITHER 88C OR 88CN. Is it possible to
install both? If so, where would you put them?

Also, are the 88SN and 88A1 worth the cost, do they materially improve
selectivity?

Anyone having hands on experience with these filters could you please
advise me?

Thanks for your help.

I have no idea what to do with the CW filters, but do know that the stock 6 kHz
filter had lousy skirt selectivity. I replaced the one in mine at the time with
either an International or Fox Tango filter, don't recall but it was a vast
improvement. So if you go with Kenwood's improved 6 kHz filter you'll be happy.

I just looked up the following:

If you've not seen it it may be of some interest to you.
