Interesting discussion which reminded me of reading about a rather 
remarkable case of RFI into a professional audio system.

In 1972 Mike Oldfield recorded Tubular Bells at a studio about 40 miles 
from the Rugby 16 kHz VLF transmitter running c. 500kW. If you attach an 
SDR to the audio from a good quality copy of Tubular Bells (e.g. CD) - 
you can read the CW being sent.

No originality claimed - details at GBR in Tubular Bells - 16 Khz makes 
it onto CD who wudda thunk!? : r/amateurradio (reddit.com)

- but rather cool I thought! Clearly someone needed to learn about pin 1 
problems - though I suspect this was long before XLR connectors were 
common..
