    Ham does require that one studies electric engineering (to a some level) and passes a test to acquire a license. Some of the equipment can either kill you or cause way too much interference potentially killing others indirectly

      Not for nothing but I got my novice and tech license in grade school.

      I didn’t know what the hell I was doing. Looking back it was basically brain dumping (and learning code well enough to pass the 5WPM test).

      Ended up getting 13WPM and general and advanced in 7th grade.

      I still have my license, just renewed it a couple months ago. But haven’t keyed up in maybe 15 years. Ain’t nobody got time for that. I just got a little handheld transceiver on temu and haven’t used it at all.

      Huh. I wonder how you do that. If the wind knocked down a tree and the tree killed someone, would the wind indirectly have killed someone? That’s kind of like the old adage “speed doesn’t kill, it’s the sudden stop”

        If you’re fucking around with your radio equipment doing something you shouldn’t and end up causing interference on, for example, aircraft frequencies or emergency service radio systems, you could be a contributing factor to an airliner crashing or an ambulance not being dispatched in a timely manner and a patient dying because they didn’t get to the hospital in time.

        You didn’t directly kill anyone, but you set up the circumstances that resulted in someone dying.

          Uhhh, no. I can’t speak to the ambulance comms, but a plane isn’t going to fall out of the sky because they can’t hear the radio. Even if they have to fly VFR and make an emergency landing (which would be the worst case). Waaay too many safeguards in place (including the pilot themselves being trained for loss of comms).

          The radio in the plane could melt and you’d still be able to communicate with ATC via light guns.

            Radios are used for more than just comms like hearing other people talking on the radio. Gps, transponders, radar, and other systems rely on radio waves to operate, and so are potentially (however unlikely) susceptible to interference from other radio equipment.

            There’s a reason we have so many safeguards built in, sometimes those systems fail, sometimes multiple systems fail at once, and you don’t want whatever you have left to go down too.

            And yes, it can certainly interfere with ambulance comms, I work in 911 dispatch, we have some redundancy with the MDTs in their vehicles and smartphone apps and such, but those systems have been known to fail on us, leaving us with just radios to communicate with our field units. My agency’s systems are a bit more advanced, but I’ve been to some rural areas where they’re using pretty basic VHF/UHF radios that I could listen in and even key up and transmit on with a $30 baofeng (the frequencies they were using were a bit outside of what’s legally permitted for ham radio use, but still within the capabilities of my radio)

              So when I said “VFR” and “light guns”, and you totally ignored it, it proved to me that you’re spouting some armchair opinions, and have never flown a plane. Nor did any of the people who downvoted me. Looks like the reddit crowd is in full swing in this thread.

              Also, I said I couldn’t speak to the ambulance radios. I have no experience with those systems, and said as much. Everything you said about them is beside the point I was making.

              You don’t need radio comms to fly or land a plane. Could a shitty ham screw up the instruments? Yes. Is that a headache for ATC and pilots? Yes. Will they crash a plane? No.

                No, it’s not besides the point because you can have issues with poor visibility and those light guns are not immune from breaking down, and then you’d really want your other communication and instruments to be functioning as they should.

                Look, I know we’re talking one in a million, worst case scenarios here, not situations that are at all likely to happen, just ones that theoretically could if Murphy’s law goes into full effect, multiple people at every level drop the ball, and the planets and stars are all aligned just so, etc.

      No, not really. You just need to memorize a few symbols, remember like two equations, and know metric prefixes. You could learn it in a week or so just doing practice tests.
