Ive downloaded most of these over a few years off the internet. Use utorrent and btjunkie.org and you can amass a huge .pdf book library i mean there are 100s of GBs of books out there in pdf format. Get what you think you will need. Im got things pertinent to my interests medicine, science, magazine.

Very good, we need more people like you: Just an interesting project that you would like to consider:

Downloading wikipedia:
en.wikipedia.org...

The 7z file takes a few gbs to download but when unparsed it takes a few 100GB of storage, with no pictures.

I think an external HD with entire wikipedia would be a good resource to have at home with no communications.

Two Essential books for radio communications especially if you have digital data. Imagine you can take screencaptures of your laptop and save it as a .jpg and transmit the file. Very Very critical in my opinion. I think this is very great.

Yes Ive been looking into this now. Recall anyone who has a wireless network card essentially has a 2.4 Ghz Radio unit that transmits digital data and is operated by a computer.

HSMM is an emerging field for amateurs that can use this to digitally transmit voice, video, images, chat in point to point communications, I am very excited about this.

Amatuer radio, is an excellent means of communication. I've been a licensed operator for going on 30 years. If you aren't licensed, I suggest to everyone that they take the testing and acquire one. These days, it's a matter of studying a book, and taking a multiple choice test, which is cheap, about $6.00. Most communities have clubs, you can get tons of information and help from them.

Just a couple of points though. Radios require a power source. In a disaster scenario, availability of electrical power is an unknown. Unless you own a generator, or have a VERY large hamster wheel.....well, never mind. Anyway, one solution is deep cycle car batteries, or RV types. You can even use solar for recharging them. You'll have to have something like that anyway, if you plan to put up a "repeater" site on top of a mountain or tall building.

You can run a handheld, or even a mobile radio off a car battery for a relatively long period of time. But, sooner or later, you need to recharge, or replace it.

The other thing you have to consider, what range or distance are you wanting to communicate? For "local", you'll have to use the higher bands, 50Mhz on up, preferrably the 2 meter band 144-148 Mhz, as a low point.

For further out, you need to go 50 Mhz or lower. Just the physics of wavelength. You talk around the world on lowband, but it's useless for reaching your buddy 30 miles away.

Lots of stuff to consider, and be aware of. Yeah, it would be handy in a disaster, as long as you cover the other issues, but I recommend it even in normal times. I've saved lots of money over the years by talking to my wife via radio traveling to and from work. Them there cell phones cost MONEY.

Once you pay for the radio, pretty much everything else if FREE. In fact, you can't charge for anything over the radio. The FCC frowns heavily on that. Thankfully.

Sorry to dig this up but I just saw a scientific american article talking about just what we discussed a few months ago...looks like i beat them...but here it is

www.scientificamerican.com...



In this era of Facebook, Twitter and the iPhone, it is easy to take for granted our ability to connect to the world. Yet communication is most critical precisely at those times when the communications infrastructure is lost. In Haiti, for example, satellite phones provided by aid agencies were the primary method of communication for days following the tragic earthquake earlier this year. But even ordinary events such as a power outage could cripple the cell phone infrastructure, turning our primary emergency contact devices into glowing paperweights.
