    I wondered that, myself so I disconnect all grounds including the antenna and tested the grounds for the radio's ground wire and at the bracket that holds up the rear casing of the radio with a test light. I put the test light clip on the positive power source and touched the test light tip to the bracket and the light came on. Then, I touched the tip to the screw I am using for the radio's ground wire and it came on again. Since the antenna wire itself can ground it, I left the casing bracket and the ground wire disconnected and plugged in the antenna cable. The radio lit up and began to play. So, as near as I can tell, all 3 grounds are working properly.
    This really sucks but, like all other problems, I AM GOING TO BEAT IT! Somehow, anyway! :)

    You could be right about the increase of rpm changing the noise but stranger things have happened. When you do find the problem dont forget to tell us the cure.

    Is your radio wired direct to battery or key on circuit. Make sure your not tapped into the ignition circuit.

    Its wired to the fuse block. I'm gonna try putting it on a different terminal or run straight to the battery. I'm just gonna throw every suggestion at it and see what sticks.

    Well, nothing works. It has to be something with the distributor, I think. I unplugged the alternator. Made sure the blower is turned off, too. Only thing that is spinning is the crank and the distributor. If it was a problem with the radio itself, it would buzz with the engine on or off. Only buzzes with engine on.

    Is your ground from the cowl to the hood missing? It isn't a wire but a a flat horseshoe shaped piece of metal with jagged teeth on the end that makes contact with the hood. They are for radio noise and should be mounted on the cowl in front of where the antenna connects to the windshield. If you had a fender mounted antenna it would be mounted on the cowl nearest to the fender where the antenna is. Most of the time they are missing you can get them off ebay for about $12.00 just something else to check.
