Found it. It was the fridge, just as I'd suspected. It's in direct LOS of where I read from.

I folded up my tripod into a monopod, turned on the H4, and walked straight into the kitchen with the recorder pointed directly at the fridge. Recorded that for ~20 seconds, then turned around and walked back to my seat on the couch and turned the H4 back to its normal position.
Here's the spectrogram: (Note that none of this noise has been present in my previous recordings, that I can tell.)



Later this weekend I should be able to post some fore- and aft-facing pics of my recording environment.
Now, when I am gonna do some reading, all I need to do is turn off the HVAC (which I have already been doing), turn off the fridge, and teach the kids upstairs how to levitate.

I'm still thinking about picking up a pair of the furniture blankets, to deaden the wall directly behind me and the one in front; maybe try some other configurations. I've seen them in 3 different weights: 35, 40, and 65 lbs/dozen. I'm guessing the 65-pounders are what I'm looking for?

Thanks mucho, as always,

Heavy is good. You're not shipping a gift where they charge for each ounce. You want the sound to have to move the most mass.

You're already close. We could probably force your existing readings to work with clever use of filters and effects, but that's desperation method. Filters affect the sound quality and you have to remember to use them each time and for every shoot. That and the fridge goes on and off. Much better to start clean.
