Was tuning around a short time ago (~2300 UTC) and now some sporadic QRM has set in, fairly strong repetitive static across LW & MW (different than the QRM earlier in this thread). With this much QRM, not much DXing tonight.

From ~2320 to ~2340, had some sort of data that is across LW, MW, and HF, with its signal every ~16 kHz. This one is periodic and has been going on for many years. Not the water nor power meters (those are 900 MHz).
Dear FCC, you want to revitalize AM? Start with cleaning up the spectrum. Yes, I've brought that up before and will continue to do so. I always thought jamming was illegal- regardless of its intentional or not. This sort of QRM interferes with the DGPS signals and could cause problems with navigation. Safety & all of that.
