| I don't have a lot of time, but this was an interesting question. If you message me I'll dig up references. There are nuances and exceptions to almost everything I list below. The radio spectrum is a scarce resource. Two of the main reasons amateur radio users are given access to the spectrum is to help with disaster recovery and to advance the art and science of radio. Callsigns are public - you can look up anyone's to see who they are. You're required to give your callsign at the end of your transmission, and every 10 minutes. There are some limitations on content. No music, no profanity, no commercial uses, and no encryption. netiquette varies based on what you are doing. In general, shorter range bands have better sound quality and are more casual. Longer range has worse sound quality (or no sound like morse or ft8). If you're on one of the shorter range bands (e.g. 70cm) you'll often find people who are keeping in touch with friends, or just looking for someone to talk to. On the longer range, you'll run into stuff like contests - all the other person wants to know is who you are, and where you are. They're trying to see either how many contacts they can make in a period of time or how far away they're able to make contacts. There are "formal traffic" nets - which pass messages. Local nets will route traffic they can't deliver to regional nets, and then back down to local nets. Usually they just pass practice traffic around - until a disaster occurs and they are needed.

You can find the Technician exam pool online in several formats. https://www.arrl.org/files/file/VEs/2018-2022%20Tech%20Class... Edit: I forgot about you abuse question. Hams tend to police their own or will work with the FCC to report people misusing the airwaves. The practice version of this is called "fox hunting" - where someone places a transmitter and you try to find it. Most hams care about keeping the hobby alive. If they find someone who's broadcasting with too much power or without a license usually they'll try to work with that person to correct the behavior. If that doesn't work, they'll often work with the FCC. |
