content: Title says it all. An old unit I have, that receives but does not transmit.Had no luck finding schematics on the net. Only the operators guide.Are Uniden one of those companies that publish no technical information for their products?

I have shelves full of those great HP and Tek manuals, and that excellent documentation is a major reason why I prefer equipment from that era.To me it seems outrageous that companies today expect you to buy hugely expensive gear, and give you *nothing* in the way of technical information that you'd need to service it.

content: Quote from: aargee on August 14, 2013, 09:33:03 pmThanks! Replied to your email.Annoying isn't it? I have an old Trio (Kenwood) CS2110 scope, that's still my standard workbench unit. Had it since sometime in the 80s. I've been trying for decades to get its service manual, though so far nothing went wrong with it. Just recently found a copy with one of the manual sellers, but on arrival it turned out to be a photocopy. Good enough, and they dropped the price when they discovered the thing listed in their stock database wasn't an original. But still disappointing.Edit: And thank you very much, those are the UH040XR circuits all right.Hmm... I suppose the absence of these on the net suggests Uniden is a grumpy spoilsport and will issue copyright takedown demands if, for instance, I posted them here?
