I just spoke to the factory about your hum problem.
They did have a bad batch of wall warts that over time,where the winding inside the wart(transformer) would loosen and starts to hum. The warmer it gets.....the hum gets louder.
They recommend to send the remote unit back to them so they can rectify the problem and in the mean time put the 7 pin din plug back into the socket on the rear of the tuner. If you lost the plug, they will send one to you.
Ask for Larry or Vince at Magnum Dynalab .

I hope this will help you out
