From the sounds of it the microprocessor is scrambled, this can be caused by a power surge or thunderstorm, unplug unit, press and hold power button for 60 seconds in an attempt to clear the processor, if this fails this will be a job for a Bose factory trained technician.
The antenna is built in. The buzz you're hearing is a 60cycle hum (electricity from a nearby appliance) Try this, put an extension cord on it and walk it around your listening room for best reception. You can also find the culprit appliance by turning items off 1 by 1 until buzz subsides.
Need to know is ti a first generation of the bose wave radio or second, could you tell what battery it has?
Also does it have an external AM antenna?
With old radio, first generation, you will need to replaced all capacitors, And I mean ALL. Radio will be good as new.
Unless radio suffered a some kind of liquid damage and then it could be anything.

there is a short in the speaker wires somewhere inside, which is not as bad as it sounds since a qualified or experienced person can just take off the case and make sure there's no wires touching and get them out of each others way.
The other cause can be electrical cross interference in your homes wiring. I like to think it's the first thing... Hope it works out, awesome radio- have a nice day!
First off how long have you owned the unit? Bose has pretty good manufacturer warranties. Usually several years up to 5 or 10 sometimes. Once I have more information I will assist you further. It sounds like either the amp or something else may be defective inside the unit. Thanks, Lee
I am having the same problem. I tried to isolate it - unplugged the charger and the buzz got much better. So I'm thinking mine must have something to do with the transformer causing interference. But I haven't solved it yet.
The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.
