I recently bought a Zenith 3000-1 on eBay a few months ago. It works well on all bands except the AM Broadcast band. I should say it's only a problem on a small segment of the AM Broadcast. I get wonderful sensitivity on most of the band, however at the lower end between 550-570 the radio goes deaf. When I turn the tuning knob I do hear strange static, ( like the tuning knob is causing the static ) so I am not sure what the problem is.
For example, I can tune all the way to the left, around 530 khz. ( we get a cuban AM station in FLA ) I get that okay, then I can tune up to 540, which I get sometimes, then after that the radio goes deaf, so 550-570 is deaf. But again I can hear static when I turn the tuning knob. Once I get to about 580 the radio springs back to life.( from 580 -1610 it's okay ) I can't figure out why. Does anybody have a suggestion ? I have used de oxit....pulled out the tuning knob and sprayed, didn't help. I have not removed the Chassis, because I don't think this is too big an issue for about 30 khz. All other bands work beautifully. FM is good, and so is any SW band. Any suggestions ?
