Why ham?

Sometimes you get bored of using standard communications (internet, cell phone, walkie talkie and want to step up your comms game. Well this is where ham radio comes in handy! Ham radios tend to have a range of several miles with access to dozens or hundreds of frequencies. Better yet, if you connect to a “repeater,” your transmission can be boosted for anywhere between 5 to 50 to hundreds of miles. Let's imagine SHTF, ham radios are great because they all transmit peer-to-peer. Along with audio transmission, you can even use ham radios to transmit images, video, or use them for internet communications – imagine wifi on steroids!

Legally – you need a license to broadcast at all and you're only allowed to broadcast on certain freqs. You need to identify yourself via callsign every time you transmit, which is publicly linked to your name and address. If you commit a radio violation, expect big fines from the FCC! Getting a license is fairly easy and costs about $15.

Illegally – as long as you don't identify yourself or transmit for too long, the worst that can happen is someone tapes your voice and tries to snitch on you. Experienced hams will ignore you or try to jam your freq if you piss them off or refuse to identify. What's really naughty is if you steal someone else's callsign – which will allow you to interact with regular hams!
