Our first honoree is KXRY 91.1/K296FT 107.1 beginning at 4:57 AM ★★★★★
Had to make a drop off at PDX this morning. Listened to 91.1 on I205 on the way there, but at the passenger drop off area Rocky Butte blocks the signal so I listened to 107.1 on the way home along SE 82nd. Reception of K296FT isn't bad along SE 82nd except behind Mt. Tabor it suffers. Anyway, at 4:57 the audio stopped abruptly (not at the end of a song) and 107.1 went dead carrier. I checked 91.1 and it, too, was sans modulation. When I got home I checked their stream and it, too was dead. At the time of this post, all three sources are still without audio. I have full quieting on 107.1 (can't get 91.1 inside). It is now almost an hour, for which I propose a 5★ rating.
A guideline for the thread might be one ★ for every twelve minute period with dead air or off air up to a maximum of 5★.
Dead air (aka DFQ) is an old radio term not to be confused with "off air" or "off the air." Dead air means the transmitters are on air but there is no modulation (audio). You can tell the difference when you are in the primary coverage area because when you are tuned to the proper frequency you will have full quieting, a radio term which describes an FM radio signal reception good enough that it creates a static free silence when no voice or music audio is being sent over the frequency.
A properly engineered station will have alarms that notify the chief operator that there is no modulation (audio). Since KXRY has no subcarrier information, dead air for over an hour is in violation of 73.1201 (http://tinyurl.com/n75kf4g). There was no ID given before the audio stopped at 4:57 AM.
Nice job, KXRY.
