@xenon Broad-band interference would suggest potentially something arcing; is there a theatre nearby that might be using a xenon arc lamp for a projector or something, maybe?

@Felthry i don't think so. we've been assuming there's a powerline or box somewhere that's arcing. the sound would be similar, right?

@xenon yeah, just a xenon arc lamp would be less of a concern
if there's arcing in a power box it would be a good idea to figure out where it is and fix it before you get a house fire

@xenon i'd be mostly concerned as to whether it's coming from inside your house/apartment/what-have-you right now--i'd suggest turning off breakers one by one and seeing if the interference goes away. It's probably not from your place but it's simple enough to check that it's not worth risking it

@Felthry yeah we can check that out. thanks
