Why I think Ham Radio & Preppers is a perfect fit...

While it is amazing that recent events in Iran are showing how the internet can aid in getting information to the outside world, it should be noted that the rest of the world is not under any form of turmoil that is effecting communication at the moment.

But if you consider a situation effecting a global crisis, the use of twitter, cellphones, youtube, and the lot would be severely impacted or eliminated.

All the current popular modes of communication are three-legged stools. Pull one leg out, and it can't support itself. Phone systems are at the mercy of power grids and the phone company, the internet is literally a network of outside supported and controlled databases which can be turned off in a instant, the same with cellphone, broadcast, satellite, and cable TV...all controlled and monitored by outside influences.

But Radio is different. A power source is it's only requirement, it is a independent entity.

And as a preferable mode of radio, the clearest front runner would be Ham Radio, it offers the most versatile, effective, long reaching, and accessable mode around.

Just consider all the Modes of Communication Ham Radio offers...

(The following is from WikiPedia)
Analog

* Amplitude Modulation (AM)
* Double Sideband Suppressed Carrier (DSB-SC)
* Independent Sideband (ISB)
* Single Sideband (SSB)
* Amplitude Modulation Equivalent (AME)

* Frequency Modulation (FM)
* Phase Modulation (PM)

* Continuous Wave (CW)

Image Modes

* Amateur Television, also known as Fast Scan television (ATV)
* Slow Scan Television (SSTV)
* Facsimile

Digital

Most amateur digital modes are transmitted by inserting audio into the microphone input of a radio and using an analog scheme, such as amplitude modulation (AM), frequency modulation (FM), or single-sideband modulation (SSB).

* ALE Automatic Link Establishment
* AMateur Teleprinting Over Radio (AMTOR)
* D-Star
* Echolink
* Hellschreiber, also referred to as either Feld-Hell, or Hell
* Discrete multi-tone modulation modes such as Multi Tone 63 (MT63)
* Multiple Frequency-Shift Keying (MFSK) modes such as
o FSK441, JT6M, JT65, and
o Olivia MFSK
* Packet Radio (AX25)

* Automatic Position Reporting System (APRS)

* PACTOR
* Phase Shift Keying (31 baud) (PSK31)
* Spread spectrum
* Simplex Teletype Over Radio (SITOR)
* Radio Teletype (RTTY)
* 8FSK Frequency Shift Keying

Modes by Activity

The following 'modes' use no one specific modulation scheme but rather are classified by the activity of the communication.

* Earth-Moon-Earth (EME)
* Internet Radio Linking Project (IRLP)
* Low Transmitter Power (QRP)
* Satellite (OSCAR)



I'm going to be getting my "shack" ready to move it to the local Field Day site for this weekend, but I'll be up on 7.245 at 9PM EST ready to join the APN.

I'll see you on the radio.
