Maybe the old transmitter has an input jack for a microphone. With a tube preamp? And how many people will have vacuum tube portable AM radios with fresh batteries? I would assume that the poweline would be dead. |

Most Basic Receiver?
No way I could connect this post to color TV so I'm not even going to try
The most basic non-active non-germanium non-silicon diode receiver I can conjure up is from my youth: a 50-foot length of antenna wire coupled to a hand-wound inductor grounded to a water pipe and feeding a razor blade/graphite detector (pencil 'lead' touching a Gillette razor blade -- Bright Star brand worked best but Gillette's were easier to get) with a single 'high impedance' earphone.

Also, I remember a college professor of mine talking about this very issue of what would happen to the solid state equipment, and he stated that equipment could be protected from the pulse if it was enclosed in a "faraday cage," which is a type of RF shielding. |

Hollow state and EMP Protection
As a communications engineer, I began to look into what might happen to a modern emergency communication system in the event that *something* went down.
I came across a paper at this site which tweaked my interest in EMP: http://www.fas.org/spp/military/program/asat/haleos.pdf Here's a reference for EMP protection: http://www.aussurvivalist.com/nuclear/empprotection.htm It would be hard to verify if these methods of protection really work though. I guess my Toyota BJ-73 would probably be dead after something like an EMP. Sigh... |

I'm a little dumb on this stuff, but...my old '67 Chevy has points/condenser-but how about the survival of the voltage regulator?
There was a bad ice storm around here about 10 years ago-no electric anywhere around. And no gas stations open. But there was an old store with a hand crank kersosene pump and that kept my grandfather from freezing. I tried to give the old storekeeper $20 for a 5 gallon can of kero but he refused to take the bonus.

I'm in BC, Canada. Anything 15 years or older can be imported with little or no problem. Right hand drive Land Cruisers from Japan abound here, but they really suck when going through a drive through or the border...
There are some form of electronic controls on the truck (turbo timer, timing belt alarm, etc), but I haven't had the time to tear into it. |
