Who, What, When, Where and Why.
This is NOT an end all be all post, but I think I'm building a small habit of long posts. Whether or not you're already familiar with radio or not even sure that you want to it's important for a member of the family, team, unit to know how to ascertain and deseminate information. What information? All Available, as the old saying goes, the more you know! Or my favorite from morning cartoons, KNOWING IS HALF THE BATTLE.
The five W questions are just that, they're questions, they should be answered.
WHO, do you listen to/for. Public emergency services, ham radio operations, broadcasters, Citizen radio networks, etcetera.
WHAT, what are you listening to/for local information, regional situations, entertainment, world response, what are the group members doing?
WHEN, do you monitor in the morning, day, afternoon, evening, night. Do you listen at scheduled times for a particular thing like radio nets, or some other reason maybe your power is limited so keeping radios on all the time is not feasible for you.
WHERE? do you listen for the information. A shortwave radio will not pickup local police departments.
WHY, are you listening to police, or ham radio operations, is it a valuable use of power and time?
Now for the main dish, red meat and red potatoes. One of the more difficult is the WHERE answer. You cannot find information until you know where to start looking for it. The radio world is a vast, cavernous place and stumbling around it you'll surely find your way around but it's much better to have a flashlight and or a map. Enter the Radio Spectrum allocation and band plans.
Allocation of frequencies means there's certain sections of the radio spectrum where certain activities take place based on the properties and characteristics of the particular part of the spectrum and consideration for the intended use of it. Low frequencies such as AM broadcast frequencies and many ham and military units use low frequencies for wide areas state, regional, or international Communications. These can range from 1.3MHz to 30Mhz
From 30Mhz to 300Mhz you'll find local radio services such as FM radio stations and the Top 40 Countdown amateur radio stations, MURS radio service, police fire ems, the VHF AM airband, and more.
From 300Mhz to 3000MHz you'll find a trail mix of radio from businesses, FRS/GMRS, amature radio, trunked police systems, cellular phone signals (Civilian scanners have these blocked) security wireless systems, WiFi networks, data point to point . Below is an image of the Amateur Radio band plan and frequency allocations for the United States. If you have ANY questions, comments, additional information don't hesitate to post it.

Thank you for a comprehensive overview. I’m not sure if you answered my question. Since it is so vast, and there are so many options available, after I answer the five questions are there Ham operator clubs? How can I find local groups or even just one Ham to learn from? I Love to learn new things. Especially practical ones that have utilitarian applications and may be life saving. Thanks again P.T.
For local communications You basically need to study to get your technician license first , you can find pdf print-outs with all the answers you just have to memorize it to take the test.

Great channel on youtube is "The Ham Whisperer" he has videos for each section of the technician exam and he gives you little tricks to remember the answers when he can..
@Cherie that's awesome. You're in luck right here on the @Bear Independent forum there's a multitude of licenced and future licenced ham operators here already. Myself, @TyMoore and @KD9PREPPER are known verified hams, and @JS Badger and @Big Squirrel are possibly future hams and at least in regards to Squirrel, a former military Radio-telephone operator (RTO)
Right on, excellent post. I have an icom5100a radio and i love the thing. im more new to HAM radiio but learning slowly here and there as I can. I listen to the local repeater systems etc.... working on getting my rig to run on solar... 73's.
Thanks for the info. I'm a HAM operator and have a shortwave. It's hard still to find good info.
