[Repeater-Builder] Re: Kenwood Service Manuals (TOS/COS question)
No problem trying to help you out... And now a 50 cent plug. As a fully Authorized Kenwood Dealer AND Service Station (for repairs) and I should be able to provide access to available Service Manuals. Many of the Service Manuals for the older radios are/were only available in printed form (versus an available PDF version more easily sent by Email attachment). I probably have a shop copy for your radio and I could also check on an available printed version to sell if you really wanted one. I'd be happy to offer that service. But there are many similar sounding (written) model numbers for radios that are quite different from each other so you/I have to do the proper homework to ensure you end up with the proper manual. A Kenwood tk-860 is not the same radio as a tk-860g is not the exact same radio as a tk-860H. I hope you get the idea that I'd like to avoid ordering the wrong manual(s) where possible. One last item... I'm up to my arse in California Alligators right now... meaning (regardless of the posts you see here) my time is almost 100% on some very special high-level projects with really short time-to-complete deadlines. So I haven't been as accessible or replying to Emails and phone calls as I would like. So if you need to reach me, please be patient and pestering with Email is probably the best way. But I/we will be happy to try and help you as our available time allows. I guess I/we should be happy to report things are very busy right now. Thanks much, Resume ALL-SKATE, All skate slow and safe. :-) cheers, skipp skipp025 at yahoo.com J C jcar...@... wrote: Thanks Skipp! I will investigate further. The one thing I don't have for this radio is a service manual. I will try to scrounge one up. Thanks again! --- In Repeater-Builder@yahoogroups.com, skipp025 skipp025@ wrote: I replied to Jordan direct to say that I'll post some of the answers over here for all to see. First off, deal with the tk-860H, which is different from a tk-860g... and I believe the H is the higher power version of the plain tk-860. The labels on the KCT-19 pins/wires will change but the PTT and COR wires are KCT-19 pin 8 and 11 or 13. The function of the radio cor out logic being tied to CTCSS and/or Carrier Squelch is dependent on the specific radio. Some of the earlier 1995 era mobiles required a few internal hardware changes to bring out a Tone Detected COR function from the KTC-19 connector. Was not a problem in most all later model radios... So I suspect you'll have to do a bit of minor hardware modifications to change the COR output line from Carrier Squelch to CTCSS activation. One application note I have here regarding pin 13 operation for Radio COR Output: Solder the two anodes of D205 together to route the audio mute signal out to the KCT-19 cable. Refer to page 55 of the Kenwood manual for parts location. I suspect the pin 13 cor output label is wrong and you should investigate using pin 11 as the cor output as indicated on most other kenwood radio model. The TK-860H is an older radio and it's connection information to external devices (the outside world) is a bit vague. You'd probably need a Service Manual for that specific radio model to sort out the proper CTCSS routed to cor output logic/wire configuration. The TK-981 follows the convention of newer mobiles so its COR should be tied to CTCSS. Otherwise post a want or email me direct again. cheers, skipp ps: I have a ton of message from group members I'll try to respond back to asap... things have been nuts as of late, which I guess is a good thing.

[Repeater-Builder] Duplexer parts
I have an old Phelps Dodge VHF Duplexer that has a frozen air variable. The Duplexer is a part# 499-509 and covers 144-174. The air variable in question is stamped 167-202 and is split stator about 1 3/8 square. Anybody know where I might find a suitable replacement, I haven't had any luck where I've been looking.

Re: [Repeater-Builder] Duplexer parts
I already found that one, thanks anyway, the 167-205 is close but not enough plates, mine has 6 rotor and 6 stator. Physical size is right though, maybe this cap was made by Johnson also since the numbers are close.

[Repeater-Builder] Wanted: G.E. VHF HB UHS preamp
Bought one several years ago from Kevin @ the Repeater-Builder booth in Dayton. Works very well (~0.13 µV for 12 dB SINAD on the MVP it's in), but now I need another one. Got another one, Kevin? If not, does anyone else? BTW, I did the antenna-load sensitivity substitution test last night on 2 MVPs, one with one without the preamp. The MVP with no preamp showed ~5 dB SINAD degradation between the antenna load. With that much noise coming down the antenna, reducing the noise figure of the RX doesn't help much, maybe a dB or two. But once you throw in the duplexer loss, which in this case is 2.1 dB, the antenna noise is reduced to only 3 dB over the load. Now the preamp improves actual sensitivity by 3 dB, which is just enough to make it worthwhile to use IMO. In addition, this will be for a portapeater that will be deployed in a rural area so the antenna noise will probably be lower. Bob NO6B

[Repeater-Builder] STX Model Configurations / Nomenclature
Not sure if Nomencature is strictly GE terminology, but I used it all the time now when dealing with model number breakdowns. I have a room full of assorted Motorlola STX portables. I am trying to make sense of these sticks and want to get them in the right spot in our shop. In other words I want to separate them by bandwidth, and capabilities. I've tried several forums, including BatBoard, in vain. Google searches turn up Batteries for this thing, but nothing specific. Can anyone out there help me out, or point me in the right direction please? Thanks! John Hymes La Rue Communications 10 S. Aurora Street Stockton, CA 95202

Re: [Repeater-Builder] Cooling Fans, which brand?
At 4/12/2010 22:43, you wrote: Hello to group, Anyone have a brand they recomend for a no noise, reliable fan. I didnt know whether to go with brushless,ball bearing,AC, or DC etc. Also should the power leads be sheilded and have a separate supply if DC.. Any filters recomended also.. I prefer AC fans because they generate less noise. I do have some 12 V CPU fans on the backs of a couple of MVPs in service, but have had problems with low levels of fan noise on some of them. If you have a choice, AC fans are easier to work with IMO. Bob NO6B
