How many of you are regularly using the electronics material found in the tests? And I mean those that weren't already doing the same in your job or other hobby before you aced the Extra. Me, after the tests, I couldn't even tell you Ohm's Law without looking it up. I've never needed it, and can google it in a few seconds if I ever did. You'd need more test/repair gear than the rest of your station is worth to work on today's micro-sized board components. I see at least half a dozen "vacuum tube" questions on the Extra. Who the heck but the nostalgic are still using tubes? Those who prefer the "warmth" of AM phone? Yet I can think of at least twice as many questions more relevant to gear and operating that I'd wager would be more apropos to today's recent licensee. I figure there are better things to test for than whether or not you know what an L/C circuit is. Say, better familiarity with the 100s of modes available at our fingertips, software, SDRs, etc. Something from THIS century. Having reviewed the Extra Class test recently, 90% of it has nothing directly to do with what I use in this hobby.
