What exactly is radio

An engineer can design the complete working schematic for a ham radio, but when it comes to putting it together, he may have the hardest time stripping the wires, soldering the connections, etc. Nope. These daze, engineers do all their design work on a computah. The design process is called direct to manufacturer. There is no hand built prototype stage. They don't need to strip wires or solder anything. Worst case is they might use a hot air SMT rework station to replace a part, or fix a layout error. If it doesn't work right, the engineer goes back to the computah simulations, fixes it, and has the prototype shop robots build another revision. These are todays engineers, not the cave man variety (like me) that had to build their own prototypes, strip their own wires, and steal parts from production to build prototypes. Those days are long gone, except maybe in garage operations. Open a cell phone and tell my you can build it by hand with your soldering iron and wire stripper. But gosh darn it, once it's completely together, and fired up.... The engineer would then listen carefully and hear a distorted sounding voice and insist that the antenna wasn't working to full potential, Baloney. It's the marketing and sales guys that evaluate how something sounds. Engineers use test equipment that measure how it sounds, how well it works, and whether it complies with a multitude of specifications. The numbers are far more sensitive to anomalies than a talk test. On a rare day, there may actually be a talk test, but that's unusual. Incidentally, you can see distortion on a scope long before you can hear it. while the newly licensed short order cook steps up and turns the clarifier slightly and hears a much clearer voice, then tells the Engineer "You go tune the antenna, while I make a connection to this operator!" What's a clarifier? Is that one of those things found on a CB radio? -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
