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.
