Background : There is another Kenwood IF Filter that is design for one or more of the Kenwood Transcevers that is Listed as a YK-88S2. The YK-88S2 is a standard "Can" Solder-In type Filter and -only- and needs to be mounted on the Dash-One (-1) "Plug-In" Filter Circuit Boards used by Kenwood in some of their Transcivers and the R-5000 Receiver. The YK-88S2 Filter can be used by swapped-it-out with an existing Filter that is mounted on the Circuit Board of the Drop-In Filter for the Kenwood R-5000 Receiver. IIRC - The YK-88S2 is designed to work on 8.83 MHz and has the same size and circuit characteristis as the other Filters designed for the Kenwood R-5000 Receiver. Reference Link/URL for the YK-88S2 Filterhttp://jg1xlv.jp-au.net/yk88s2.htm My reading of the Numbers for the YK-88S2 Filter : The -6 dB Bandwidth would be 3 kHz (2x1.5) The -20 dB Bandwidth would be 3.8 kHz (2x1.9) The -60 dB Bandwidth would be 5.5 kHz (2x2.75)http://jg1xlv.jp-au.net/yk88s2-spec.htm Now comparison this to the KY-88A-1 Filter The -6 dB Bandwidth would be 6.0 kHz The -20 dB Bandwidth would be ?.? kHz The -60 dB Bandwidth would be 11 kHz My Conclusion is that the Kenwood YK-88S2 (3.0 kHz) would appear to be usable as a Very-Wide SSB IF Filter -and/or- a Very-Narrow AM/MW IF Filterhttp://jg1xlv.jp-au.net/yk88s2-spec.htm The reason for this posting is -if- the Standard Solder-in IF Filter Board Mounted of the Kenwood R-5000 Receiver will take a Kenwood YK-88S2 IF Filter : It should -but- has anyone had a problem ? ? ? ? ? =IF= The Kenwood YK-88S2 IF Filter is a Drop-in-Fit -then- I would like to configure a Kenwood R-5000 Receiver with the following Filters : 1st IF Filter = YK88-A1 - AM 6 kHz for Wide AM 2nd IF Filter = YK88S2 - AM 3 kHz for Narrow AM 3rd IF Filter = YK88S-1 - SSB 2.4 kHz for Very Narrow AM This Receiver would be "Set-Up" specifically for Shortwave Radio Broadcast Program Listening and not for Amateur Radio SSB Reception. Once Again - Two Questions : # 1 - Has anyone any more information on the Kenwood { Trio } YK88S2 IF Filter ? # 2 - Has anyone any used the Kenwood { Trio } YK88S2 IF Filter in any Rigs ? some say - i would if i could . . . -while- i simply say 'kenwood' ~ RHF *.

The R-5000 has four filter slots with designated R5000 filters giving 6khz (YK88a optional), 4khz (YK88S), 1.8khz (YK88SN optional) and CW (two filters available). YK88S2 might make sense in filter position 2 if it fits and if a really narrow AM filter was needed. YK88S1 would appear to largely duplicate the YK88SN filter and I doubt any noticable benefit would be gained in that swap. I've got the full complement of optional R5000 filters and find them to be a good mix of widths. Nice to see that something else is available though. |

, RHF wrote: YK-88A-1 = 6 kHz "Optional" AM Filter - Plug-In YK-88A = 6 kHz "Optional" AM Filter - Solder-In My old TS430 had the solder-in filters. The newer TS-690 (450) has plug-in filters. I understood that the only difference between older and newer YK-88 series filters was the circuit board, denoted by the -1 suffix. So, if you need a solder-in YK-88SN for example, you should be able to unsolder the filter from the YK-88SN-1 circuit board and use that. Are there some matching components on the circuit board that I missed? Fred K4DII |
