I are an engineer and I know which end of the soldering iron to grab. Eg. 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. Unless you were in a very small operation or talking about REALLY ancient times, engineers as a general rule never did mundane tasks. Those were left to other, lesser paid people, like technicians, draftsmen, and typists. No one in their right mind would pay an engineer to build and test a prototype, draw up the formal schematics, or type up the documentation when there are other people who could do that faster and at a much lower hourly rate. 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. Most of the places I worked, the testing was done by techicians who wrote up a test results report for the engineers and the engineers only got involved if something was hinky in the test results. |
