What use is an F-call? Man-made interference is a wonderful thing. It allows you to appreciate that there are both people and morons on air. Some people become morons, either by accident, or on purpose, but every now and then you have special people who share our airwaves. In case you're wondering, a moron is someone with the intellectual age between 8 and 12. In the past we as amateurs have chosen to ignore them. In general that works pretty well. The moron doesn't know that they're having any effect and they soon move on to greener pastures, hopefully one six foot under, but that's a story for another day. I have a special friend. He's special because he thinks it's particularly funny to disrupt a weekly net that I host called F-troop. He likes to send DTMF tones, play audio tracks and generally be a pain in the rear. This isn't a new thing. I've been logging activity from this moron since April 2012. He comes in every now and then, completely disrupts the net and then pisses off. You could infer from this that I'm angry. That's not true. I'm annoyed that other Amateurs bear the brunt of this particular moron's fetish for my on-air activities. It's a sad day when you cannot run an introductory amateur radio net without special attention from people who clearly haven't understood that large fines exist specifically for the likes of them. I'm glad to report than when we do actually catch this particular moron, there will be a long list of his behavior and if we're particularly fortunate their fine will cost them their house. We can only dream. Got any morons on your repeater? Got any tips. Share them with the community. I'm Onno VK6FLAB
