I almost hesitate to contribute to this pissing contest, but....
I'm sorry...did I mean "Spirited Debate" (LOL)
I am next to Houston, TX.
During the three weeks without electricity we experienced here from IKE,
not one friggin radio station had ANY information about ANYTHING.
I know because we got sick of TV repeating the same crap over and over
and resorted to music for entertainment often...
DO NOT rely on radio for shelter listings, FEMA food outlets, any usefull info at all!
They have a fixed budget is my guess, all I know is except for a sentence once an hour or so,
they offered no help whatsoever.
We jumped across about six stations trying to find music to match our taste's,
so I am not saying that about just one radio station.
I have a huge battery bank and effecient inverters with a generator to charge them every four days.
So perhaps I don't coun't as a good power outage example.
But a CECB that uses an external wall-wart/power-brick,
with a aftermarket/home-made cord to feed 12-Volts to it.
Paired with one of those laptop DVD players with A/V inputs
would last a fair amount of time on the average car battery.
Only the DVD motor uses anything substantial on them...
eBay is flooded with super inexpensive portable TV's right now.
They are analog of course, but that is fine to feed a CECB into.
Still to this day there are no emergency radios that receive the new ATSC digital audio like the old emergency radios do.
Sure the AM/FM part works, but they still include analog TV.
So if your relying on a radio in a crisis, your basicly screwed!
Don't do it, just don't do it.
Have a radio too of course,
but get a TV setup of some kind!
An amplified indoor antenna can run off of 12-Volts too.
Those little round inline preamps (~10-Db Gain) from RS are negative ground and handle 12-Volts nicely.
Their gain is meager and shouldn't overload your CECB if your rural like us.Radio Shack Catalog # 15-1170
Please note RS is now way overpriced on them, they are about $10 on eBay or if you google them from anywhere else.
They are imported from one manufacture,
so just note the picture of the aluminum barrel and purchase accordingly.
The "Injector" will differ a lot, but the barrel is from one manufacturer.
The "Injector" has only one DC-Blocking ceramic bypass capacitor in it by the way...
You can get two 1" long male-to-male- couplers to attach both the preamp then the injector right to the back of your CECB and plug almost anything into it for an antenna if your resonably close to your cities antenna farm.
Don't forget to check that all products are negative ground before connecting them all to each other.
If one is positive ground you'll just make smoke...
