I think I know what your problem is with the funny noises from the mics. This is a new problem with the less expensive wireless mics. It's cell phone interference. The inexpensive mics don't have the proper filtering to fight the interference from cell phones. Take a cell phone and hold it next to a boom box while you are actively on the phone if that is a similar noise to what you heard from you mics, send them back because you'll never get rid of the interference. I had the same problem with some inexpensive wireless systems I bought about a year back.
This was not cell phone interference...I have experienced that before and with the VHF mics. The one I purchased was UHF...still...it wasn't the cell phone problem.
