The short answer, Yes you will have trouble when it comes to transmitting and being useful not only to yourself, but to your family and others.
The long answer,
When I became a ham, I came from a public safety background of radios. I was use to the "program, install, forget" mentality on conventional radio traffic. After getting my license and putting some effort into learning, I discovered a great many things, such as different modes being used on different frequencies, how my transmissions on the radio can affect other transmissions, even when they are not on the same frequencie, even the general "emergency disaster drill" I particiated in was way different than I had expected. Through ham radio I found that just a simple car battery may not be enough to keep my HT going long enough to get through some incidents and made simple changes to better prepare myself for posible eventualitys. Heck I even merged equipment you may not think about, such as a weather station to help me follow my local weather patterns so I can be prepaired should a storm be comming when mains are down.
The fact is I have been around ham radio and I am still learning. APRS, TNC's, HF, portable repeater building, digital modes, the list goes on. Without a license all you have are the manuals to go by. When the time comes to actually use the equipment you wont know simple things like radio courtesy, (I dont know how many times during drills where "that guy" breaks in and just disrupts everything just because he feels hes more important,) or you'll find yourself transmitting conventional when others are using digital.
If you have the qualifications you claim, getting a license should be very very easy. The test is mostly common sense stuff, the rest has to do with electrical information, and a little about radio operation and safety. Go for it, even if you only use it once or twice a year, it will help you at least get familure with your radio and operating practices. Maybe you will even find a new hobby that will bring you beyond what you expected you could get out of your radio.
You never know till you try it!
Won't get very far? Why is that? I understand that operating a ham radio legally and keeping within the laws will require study time to become educated in the practice, but I'm not talking about that type of "its my hobby" situation. I am not interested at getting a license and becoming a radio operator.
In what preppers call a "SHTF" situation, I want to fire it up and be able to listen to what's being said about whatever national emergency is happening and to be able to call for help if my life depended on it.. or at the very least share information.
Lets face it, when the zombies are walking around the streets, federal FCC laws won't mean anything.
So, beyond the obvious hurdle of being legal, are you suggesting that I will have technical difficulties transmitting or receiving at some useful level that serves my purpose?
What am I missing or don't understand?
