Been on the air since '84 and although there was only bbs's and no Internet and radio coming out WAYYYYY before computers you are correct. You can look at beacons as websites that are static ( you mention IP addresses ) and DDOS would be as for example with CB we used to make RF bombs with ol Tyco RC Car remote controls since they are at 15A ( there are alpha channels where there is 20khz space vs 10 and 1 is between 15 and 16 ) and RC car's use tones on the frequency for control so we would unpack the guts and use plastic containers and sometimes depending on your skill solar panels to charge the batteries ( easier with 2 x AA @ 3v vs a 9v ) and use some fishing line and a hook and throw it up in a tree near whom we wanted to shut up and all they could hear was a constant carrier with a tone and when they would key up it would screw up their TX too. Also , radio waves are sparks but controlled I wanted to say look at early transmitters like what was used on the Titanic its like a massive wood lathe that sparks @ 60hz. We need more radio posts on steemit vs just crytpo coins and porn so I was glad to see your post and read threw it briefly and my comments built up hence all over the map. Also if we had a nuke strike no it would not just kill the Internet and ham radio be left. Transistors and the use of geranium would put us back to the days of vacuum tubes ( i keep a boat anchor Cobra Cam 88 and Uniden 2020 just for this reason ) and the only reason the Internet would be dead is because transistors and IC's would become useless and actually most would literally short out internally and the small gold wires less than 1/100th that of a hair that connect the silicon wafer of an IC and they would burn up. Ham radio would not exist as you are thinking of it , we would all become pirates and rules and regulations world wide would not matter what so ever it would be about survival and trying to branch out to expand small groups of people and supplies. It would be more underground than how linear amplifiers transistors started getting referred to as pills , it was people selling cross tops and Valium and literally selling narcotic pills and it was just a cover up because cop car's actually had CB radios and monitored channel 9 along with scanning the local used channels to catch the pot heads and pill heads using the CB radio to deal drugs.
