Be careful - there are probably drug dealers in your basement!

All kidding aside, You have some RF in the shack. You’ve mitigated a lot of it, but you are on the right path. 

You probably have some RF getting in through the thermostat. I’ve seen a lot that just have a couple of wires and no shielding on them. Ferrite’s at the furnace on the t-stat wires might help. Otherwise, just possibly getting in through the power line to the igniter transformer, but my money is on the T-stat lines.
