Hey, thanks for the replies. I didn't know people were replying. I also posted this on tapeop forum and I have been following that more closely.
I do have a bunch of updates for you all though. If you want to see the tapeop thread, here it is:

A brief catchup. These mics seem to operate correctly almost everywhere but my apartment(Ridgewood NY, on the queens and brooklyn border). They even work almost without flaw just a short way down the hall from me. And they work perfectly in an apartment on the other end of the building.
It seems to me that it is related to the freight elevator across the hall from me. It gets really loud in places near that. It really depends on what point in space its in, not what direction I'm facing. It has a low ground buzz in one place, take one step forward and it reduces in volume a lot. Also, when pointed staight up, a high rf buzz is heard.
I have checked all the pins, and everything is hooked up properly, no shorts.
Grounding the XLR ground to the chassis is something I will try this weekend. Thanks for the tip.
So is this something you think nuemann can fix? Or should I just sell these and buy different mics, or keep them until I move?
