Default Adding Filters to R-5000 Receiver - Where to put them in IF board

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.

Jim

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.

Frankly Jim, I wouldn't spend a cent on upgrading the R5000. Even with
the better filters it'performence is so far behind modern DSP radio's
that I wouldn't waste my money. I had an R5000 with the upgraded
filters for a couple of years - it never performed very well and after
the keyboard started bouncing for the second time, I got rid of it.

If you want top notch CW performance you couldn't beat an Icom
IC-746Pro - it's CW filtering is awesome. I'm sure there are some good
ones on eBay.

Good luck
