The first thing I would check is the INT / EXT antenna switch, on the back of the radio next to the RCA antenna socket. If the switch oxidises, it will affect reception on SW, and maybe MW as well? (don't remember if it affects MW).
Hope this helps,

One night I plugged it in (I never plugged it or the antenna in until use)and...nothing. It powers up, with the display, changes bands, appears to tune, (you can actually hear a little "pip-pip-pip" noise in the speaker when dialing frequencies) but no program audio from the speaker or earphone. And, yes, although always used with AC, it always had backup batteries. I have opened it, and can't seem to find anything in the realm of loose wires or connectors. Ironically, a DX-160 that I bought at the same sale and gave to a friend, is still working. Hey, my R-7000 Trans-Oceanic is fun, but the 440 had great performance AND the digital freq. Does anybody have any ideas on how to approach this thing?
