I have no way of verifying this, and I only date back to the 1950s as
both ham and commercial operator. But always understood that the N (as
in QRN) meant the interference was from 'Natural' sources and the M (as
in QRM) meant that the interference was from 'Man-made' sources.
Guess only those who formulated the original Q-codes could tell
us.....and they will all be SK by now!
