Mixed, at least in my neck of the woods. I was stationed at an LP-1 station which was monitoring a PEP station directly. On my end, the test went fine without intervention. Please excuse the cellphone video, I am used to my good camera, which I left at home.
Many others in the New York area had problems. Stations with newer SAGE (Blue front) CAP-capable EAS ENDECS had issues, even the ones that were also monitoring the PEP stations directly.
Many of those stations broadcast the header tones and about 10 seconds of audio. The audio abruptly stops and is followed by twenty seconds of dead air followed by the EOM. I can speculate that the SAGE EAS units should be checked for proper configuration and be tested back to back while receiving duplicate messages from different sources spaced apart by ten seconds.
Several stations downstream from the LP-1 stations did not receive anything at all. Others received the alert tones but no audio, some had high levels of background noise, thirty seconds of static, audio cut off, etc. All in all, most would look at this and say “Thank God it wasn’t a real emergency.” Silver lining: For all those that are concerned that the federal government will attempt to diabolically take over the entire broadcast spectrum and say evil things; Doh! foiled again.
