I've gotten tired if the Internet because people abuse the privilege and perpetuate incorrect information repeatedly. But today I learned something and I want to share it with the hope that hams everywhere will perpetuate it instead of some of the wonky unverified tomfoolery that gets passed around. By the way: I have passed around my fair share if tomfoolery. I'm trying to do better. And so, I give you: 2m simplex information that doesn't suck. I'm a couple hundred dollars into fixing a path problem that can't be fixed. It started with a weak copy on a real nice and very funny fellow 22 nautical miles from me. He hates repeaters and so do I. We get on great. Well, when we can talk. I knew my station was marginal. His equipment is top shelf. I'm at fault so I started upgrading. And the net result is abysmal so far. New low loss coax and gain antenna. I also have a rotator and a beam in my collection of parts but they aren't in the circuit yet. After the first round of mods I'm irritated. I don't like guess-work that costs $$. And so: I went googlin'. I learned to place dots on maps and drone lines between them. Then I learned to evaluate the terrain along that line (actual line of sight!) Holy crap no wonder we need so much power. We are working directly into the dirt (plus a stadium and several overpasses). It's a thought twenty miles right? Our height difference is only about 75 ft over rolling terrain but boy does it matter. This all made e curious for a fix. I read all kinds of vhf propagation writings before something finally occurred to me: I don't know where the horizon is and I'm not alone. According to google earth, the horizon is about three miles from my house (relative to my friend house). His horizon is close to his house (relative to my house). So you see: the horizon isn't some thing way out there on the horizon. It's some thing between you and your friends house. It might be several things. As it happens RCA figured out that horizontal polarization works better than vertical over-the-horizon. So someone wrote in a ham book/website/forum that horizontal is better for weak signal work over-the-horizon and a lot if people (including me) just really didn't grasp what that actually means. Nevermind the modulation. Forget it. Use horizontal polarization with fm all you want. Those crossed yagi beams are starting to look like the ticket. Anyway: find your horizon. The real one. It's kinda important.
