During the Boston Marathon bombings, news coverage from WRKO 680 and WBZ 1030 was simulcast for a time on FM (incl. WEEI FM 93.7 and four different CBS-owned
music FMs).The city was basically shut down one day and a manhunt was on. Much like during 9/11, there were FM simulcasts of the news/talk stations, though it went away
after the crisis ended (for the record of course Boston does have news/talk on FM via two NPR stations).
Boston like NY does have powerful news-talk stations on AM and WBZ 1030 especially can do well in the ratings. The stations I mentioned are on FM in one way--if you have an HD radio. WRKO is on the HD2 of WEEI-FM while WBZ is on the HD3 of WBZ-FM 98.5 (a sports station that tends to do well in the ratings). But how many people have HD
radios? One Boston FM talk station gave it up a couple years back and went hip hop. On the Boston AM dial there are the stations I mentioned plus the likes of ESPN,
foreign language, Radio Disney (for a couple more weeks) and so on. There are some "hometown radio stations" that cover the community with AM.
But AM in many cases won't make money and it's said 80 per cent of people listen to FM. These days you do have some listening to radio via their smartphones and computers.
It can help especially in bad reception areas due to interference, signal limitations, and so on.
These days you do have some mega news-talkers on AM but many stations have gone to syndie sports, oldies-standards, foreign. religion (often birdfed) etc. And there are those who run pirate stations on AM.
Pros--some signals range far at night. Cons--Some have to go off or reduce power; powerline and thunderstorm interference; audio quality.
It varies...with a half decent radio AM can sound fairly well, but people do prefer FM.
Maybe someday the big news/talk operations will have maybe one or two spots on FM; sports stations have moved there (WEEI and WBZ--FM Boston, and the NY ones)
and AM may be relegated to the formats I mentioned above, surviving but not necessarily thriving.
Look at what will happen with the sales of the Radio Disney stations. Will owners find having AM stations worthwhile...or will it be shut off and sold, the land the
transmitter is on being developed into something else?
Yes FM gets the attention and makes money but there's still some life on AM. (Note of course more and more car manufacturers may put on car radios without AM...)
And more on reception: I was at a Bos Red Sox game last night and found I had trouble picking up their flagship WEEI FM 93.7 on the DX setting of my Walkman.
It did come in on "local" but it mixed with music stations...overcrowded FM dial. Had the Red Sox still been on 850 I might have gotten it half decently.
But it all depends on where you are; if you work nights, say, at a factory causing interference, that ballgame will come in for you on FM. But not AM.
Or you could listen via a smartphone...but data charges can add up
