I'm not sure if you are serious or not, if you are serious you really are grossly out of touch with reality of what a disaster is. Say you are living down stream from a dam about to fail, wha tis the best way to get the message out when all other forms of communications are gone? (this should sound familiar if you are keeping up with the news).
so all other widely used communications are gone.. no TV, no cellular, no landlines.. ok, but why is it being taken as fact if a disaster wipes out all communication, that FM will somehow still remain? or why is it being assumed that if all communication is down, that the dude sitting behind the mic in a FM broadcast booth 30 miles away has the relevant information.. in the event you've outlined, the broadcaster is not going to warn you to get out.. no, he'll tell the living in about 4hrs from now that you have drowned.. she's reporting info that she has limited access to (the same limits you've been given).. definitely not warning you of any immediate dangers other than what she may see with her own eyes two counties over..
but ok, i'll play along..
what is the best way to get a message out? the freaking dam warning system..
e v e r y b o d y will know about it then.. not those that just happen to be tuned in to FM radio at that time..
or are we to just assume everybody (or even the majority of) would be huddled around FM radios in the event of emergency?
further-- you're coming up with such an unlikely scenario.. odds being
maybe a once-in-10,000 year event where you're downstream from a failing dam while
all communcation other than mouth-to-ear is gone due to disaster, the warning system has also failed, except FM radio which remains fine and the broadcaster has the relevant info?
it's just so completely unlikely, right?
but hey, just so we're clear.. if i happened to be in this event, i'd be glad if i could tune into FM.
If there is a nuclear event radio is the most useful way to keep people informed about fallout and where it will require that you take cover.
again, a highly (highly!) unlikely scenario..
one that involves being in a nuclear event... you're already in an area where one nuke wiped out communication (except FM), you're still alive... and thankfully, you have FM radio to know that you should take cover?
i'm sorry but these are very very weak arguments.
Actually two way communications is important but it isn't a useful way to get a message out to a large number of people. You see you are looking at a totally different need here, that is to spread known information to the widest number of people possible.
to get the message out to the widest number of people possible, you would use cellular.. because your phone doesn't need to be awake and tuned in to get a message out.
with a cell phone, nearly every single person with an active phone will get the message..
with FM enabled cell phones and an FM based message... maybe..
maybe, 5% of people will get the message.. those who have the phones awake and tuned in.. (but tbh, i think it would be
f a r less than 5%)
(or in localized areas, you'd use loud speakers.. probably will work the best to communicate a message to the most amount of people.. like, this is how emergency messages are being done in Puerto Rico.. but if the comparison is only cell or FM.. then cel)
You do realize that cell tower hardening is a recent development pushed by the FCC. Frankly for some of the reasons you expressed. However cell towers do nothing for one to many communications especially if things are changing rapidly. However there is a limit to how hard you can make cell towers and frankly some where wiped out, Florida got lucky too as the storm pretty much had burnt itself out by the time the mainland got hit. You can't assume that a more powerful storm would have left all those towers in operation.
make them hardened_er..
deploy mobile towers in event of emergency..
launch drones with internet/cellular transmissions.
seriously, if you're so concerned about these disaster scenarios, you should want more modern communication than was available in the 40s.. yes, keep FM around.. i don't think you'll find anybody in this thread saying otherwise.. it's possible you're not quite clearly understanding others' points because i feel it's come down to a simple cellular internet vs FM radio argument..
and if this is the case then i'll quit discussing now.. FM vs cellular is so much of a one sided argument that it would be ridiculous to partake in such comparison.. cellular/internet is
clearly superior to FM as a means of communication.. clearly.
FM can do a
tiny bit of a support role towards internet.. yes, keep it around.. let it be what it is.. but if you're going to improve upon something for disaster scenarios.. definitely improve cell/wireless data/etc.. it will be
f a r more beneficial.
In a nut shell you miss the most important feature of radio reception and the tis one to many communications that can't be accomplished any other way.
i'm not actually sure what feature was meant to be brought to my attention through your post but...
why in the heck are people sitting around here trying to describe what FM radio is?
do any of you all actually think anybody in this thread doesn't know what FM is, how it basically works, etc? i think it's safe to say, you can quit pointing out the benefits of FM radio... everybody already knows about it.
