The FCC made the test for the extra class didn't they?
There is responsibility that goes along with having a ham license in the first place. The FCC is not going to let someone operate their equipment without knowing how to operate their equipment.
HAHAHAHAHAHAHAHAHA!!!!!!!!!!!! OMG that was funny. Say it again please. Just one more time to make my day!! Puuuulleeeeezze say it again.
Now on a slightly more serious note, you have NO idea how poorly qualified a lot of people are when they get their ticket. Memorizing the answers to the posted question pool does not in any way, shape, or form even remotely qualify as actually having gained the proper knowledge to be turned loose on the bands with 1500 watts of power.Nor does it ensure knowledge about RFI, not IMD, nor proper modulation, nor anything else really whether radio related or not. Memorizing answers is just that. It is far different than learning the background behind those answers and why the answer is what it is rather than just simply IS.
