Why Do I Need a GMRS License & How Do I Get It? - https://midlandusa.com/blogs/blog/why-do-i-need-a-gmrs-license-how-do-i-get-it?gad_source=1&gclid=Cj0KCQjwwYSwBhDcARIsAOyL0fiDdTwT1WprQwT6vC3ISttiFaJd-Qs27lPnl0DY4MnpZ6eTJzNIwYUaAkMuEALw_wcB
you navigate the FCC web site, pay your fee and you get your license.
The HAM test takes maybe a day of taking practice tests to get the answers as the test uses the same questions. You just keep running through the practice test until you get above an 85% several times. Really not hard. Nothing you really need to know much after you get your license. Once you have one, you renew for free every 10 years by just visiting the site.
I personally consider these key tools of our hobby and why I have both licenses. Everyone is different. My daughters got their HAM licenses when they were 16, 17. You don't have to know the background, just what answer matches which question. I say that as an Electronic engineer who understands the material as none of it is really needed once your radio is installed. You won't ever worry about antenna lengths etc again, but you get all the answers from taking the practice tests. The key item to know when working the HAM is verbal skills. What you can say and can't, how you identify your self and how often and other communication statements like "K0ROM mobile and Monitoring" if you want others to know you are on the net
