Protecting ALMA’s skies Whitepaper: a study of the risks posed by radio frequency interference (RFI) to ALMA today and in the near future, from both ground-based and space-based sources of radio emissions. The paper identifies the vulnerable points eof the observatory, and discusses and evaluates potential mitigation measures.

Well I finally managed to get a case opened about PG&E's ridiculous powerline RFI in our neighborhood. Their spew extends from 690kHz all the way to 54MHz and possibly beyond, with the strongest signal around 3536kHz.
I suspect what they have is effectively an accidental spark-gap transmitter. Not much range (about 200m) but inside that radius, a massive smothering of absolutely everything.
Someone is supposed to get back to me within 5 business days to troubleshoot it.
I guess given it's PG&E I should be grateful nothing is currently ablaze.

This is a worrying development: the impact of large satellite constellations, and of multiple ones of them will be strongly felt by radio astronomy…
