Don't get me wrong - there are hams that really know electronics and rf. But it seems more and more just don't have a clue. You don't have to understand electronics to be a ham, nor much of anything other than being able to memorize test answers. You could pass the Amateur Extra Class exam and know NOTHING about how to operate a real radio. But buy a radio and an antenna ... presto you are an Extra Class ham!
In fairness, in the old Australian AOCP, if you could answer the reasonably hard Theory & Regs papers, plus send & receive Morse code at the required speed, you were a "Full call", with all the benefits that implied.
Being able to actually operate a radio was not tested, so you could pass everything without ever having seen a ham radio.
In practice, it was never a problem, but interestingly, the modern "Foundation' licence requires the applicant to, under supervision, carry out a real contact with another station.
They now have a microphone and a radio. They breathe in air and blow it past their vocal chords and out come words yes ... but even smart birds can say words. So they seem to be instant experts on any subject among the following: medicine, engineering (of any kind), personal relationships, construction, oh and politics - they are the world's best political analysts!. You should listen to the local 2 meter simplex frequency for a couple of hours. You'd slit your wrists.
I could listen on our local 2 metre simplex frequency & hear "crickets", unless there was some sort of VHF contest on.
