Sorry no recording at the moment but was tuning through longwave since conditions were nice and quiet tonight and stumbled onto an AM voice signal on 407kHz. Couldn't make out much of the words but lots of numbers mentioned and heard the word "visibility" followed by more numbers. I don't recall ever hearing this before. Any info welcomed.
Could have been any one of these guys in maintenance mode...
