The other day I picked up a small LFP-based power station for cheap. Curious of what noise it spews out, I decided to power a receiver though the built-in inverter. It spews out some nasty noise, particularly strong on the AM broadcast band and 80. Doesn't appear to be as bad on higher frequency bands. There appears to be both conducted and radiated noise. I plan on experimenting with an extension cord to place it further away to mitigate the radiated emissions. I have a few split ferrite beads on hand, but It'll be a challenge getting multiple turns with an extension cord. Might have to shop for some larger ferrite beads. There is a 12 volt output that may be a bit better behaved, but it is limited to 8 amps.
Powering a radio wasn't the primary reason for buying the unit, but it would be nice to suppress the noise enough to be usable for such a purpose.
Curious how others out there dealt with a similar situation.
