QTH is Portland OR.  So we seldom get hard freezes but plenty of rain and occasional snow and freezing rain by January.  Yesterday it had cooled enough in the morning that we turned on the heat.  Since the noise was present, I turned off our furnace and switched the thermostat as well.  Didn't affect the noise.  The funny thing is that the noise can be constant for hours--including very late at night and very early morning, seven days a week.  I can find no pattern other than the change in the weather.
