Anybody else have one? Anybody have a complete service manual for one? I bought this one a year or so ago and it's been working fine. When I turn it on now, I get an 8 and then an 823 on the frequency display window. The 8 stays there. So if you input the frequency 27.185, it shows as 27.885 but it's outputting at 27.185--- and seems to be working correctly. I can't find a complete manual though that explains what that code is, let alone how to fix it. In the event that it can't be fixed by me, should I just toss it out or let it run until it just gives up completely?
