[EAS] NWS/CG Interference in NY area

[John Willkie]

Co-location generally limits interference issues to a small area surrounding the tx site; it's a relatively well-known technique to minimize intermodulation.
 
If multiple receivers (particularly monitoring receivers) have problems, the issue most likely would be on the transmit side.
