For One and All,
Need Info on the YK-88S2 IF Filter ? -for- Kenwood R-5000 Receiver http://groups.yahoo.com/group/kenwoo...0/message/2115 Also may Want-to-Buy [WTB] a YK-88S2 IF Filter -so- Does Anyone Have a YK-88S2 IF Filter : For Sale ? 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 Filter http://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 Filter http://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 |

I found Kenwood filters for my old TS-440S at International Radio 13620 Tyee
Road Umpqua OR for a reasonable price. I tried the more conventional sources such PartsStore.com but even though they listed the filters they were discontinued. The old radios from the late 80s through the mid-90s are hard to get parts for sometimes. The only draw back to ones from International were they were not direct replacement, they were mounted pn a circuit board mounted to my IF board with some double sticky foam tape. The orignal filters were hard to find without buying them off eBay as a used item for a premium price. Good luck, the filter do make a big difference, my Kenwood is used as a beater radio for our club Field Day and other outdoor events. The operators last year raved at how clear the SSB signals were over the previous FD. 73, Homer "RHF" wrote in message ...

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 |
