George,
  The hum is probably the result of the local oscilator being radiated in
to the house wiring, modulated by the AC ( rectifiers, light dimmers
etc.. ) then being picked up on the antenna.  This is common with direct
conversion receivers.  Shield the oscilator, put chokes in the power
leads etc...
