Rod, I had checked out your suggestions but did not help. I did solder the ground rivets to the chassis as Chas suggested.
Good news! The squealing is gone, now that I have corrected my wiring mistake. I had the oscillator grid wire connected to the top connection of the the antenna coil and the pin 5 of the antenna coil connected to the top connection. So basically backwards I guess. I didn't think I was going to solve this one.
My radio has what is called a wave trap but the alignment instructions don't say what to do with it so I just peaked it for the best signal at 600. Hopefully that is correct.
