OK, thats a fine figure to be going on with; but that's a sum total of all the towers and all the bands they're using and is going to look a lot like broadband noise, even when it can be seen, right? Anomalous in many ways but like listening to the conversations of the entire flock of geese: hard to see the data without more context.
Anybody with instruments sensitive enough to perceive us prolly has better things to watch anyway. The soap operas out of Betelgeuse are getting tense about now i bet.
- PaulHoule 4y agoThe 1970s analysis was that the most visible transmitters on Earth were television towers which broadcast a narrowband repetitive signal which would have been unmistakable for any natural phenomenon. More recently the conventional wisdom is that it would be pretty hard to detect modern digital signals that are approaching the Nyquist limit since these look more and more like "broadband noise". This paper is suggesting that the broadband noise is detectable as noise, not that the signals could be eavesdropped on as they are encrypted, scrambled with a chip code, etc.
