: : Question for Chris Tarr if he's here or another engineer: Would a DX'd signal be strong enough to register on a PPM monitoring device? That is, would the PPM signal DX to your device too??
: Yes it would. In fact you can decode a PPM signal by holding a meter up to a phone and have someone on the other end hold the phone handset to a speaker. The watermarking is that robust!
Okay now THAT is pretty cool. You could potentially see odd markets show up in the ratings of markets miles and miles away - think hold music at major corporations which is sometimes a radio station.
