A ham license is very easy to obtain with the easiest amount of learning for most people. The "tech" class is the lowest or first step in the list of licenses and the easiest to learn. I stuck with that license because I loved 10 meters (28-29.7 mhz), 2 meters (144-148 mhz (VHF)) and 440 (440-449.999 mhz) and most aspects of the hobby i'm involved with are withing these frequency ranges.
I belong to the counties emergency services through RACES (radio amateur civilian emergency services) as a communications tech and disaster services worker (EMT/SAR) and 99% of all communications traffic occurs within the VHF and UHF range. 140 mhz vhf through 470 mhz uhf.
This radio in the link is a great radio for the price and covers both 144-148 mhz 2 meter ham band and the 440-448 mhz ham band. It also recieves a wide range of bands. the link covers the range. I have a license to operate within the ham bands only but when tshf my license I believe will be useless. It's supposed to be against the law but...........radios including the one in the link can easily be modified to operate on an extended frequency range, my wouxun is. Again, as a HAM operator your license gives you privelegdes on HAM bands only. After tshf who knows what will be legal or illegal.
This small radio can be operated continuosly with a simple solar panel then add a car battery, an antenna cable leading to a cushcraft multi-band vertical or even a 5/7 element dual-band directional antenna. It's quick to setup and mobile enough if your on the move or sunk away somewhere but come out and setup your simple radio setup. Just with the radio putting out 5 watts and connected to a directional say up at a low 15 feet you got alot going for you that the guy with no radio has. If I can reach a repeater 120 miles away on 5 watts with a rubber ducky antenna just imagine your capabilities with this simple setup.
You can purchase without a license and this radio is the lowest on the market today. Even single band HT's are more expensive and this one is dual-band.
When shtf I will be using ANY frequency I feel is neccasary for my survival and being able to listen to a wider range of frequencies is a great benefit. You will be more informed at least of what may be going on in other areas around you.
Having a handheld is just the start. check out more of the hobby and you may find other aspects you'll be interested in for survival.
