However, they were still giving the old 2nd class exam, which was mostly about tube technology and which shared nothing in common with the Extra Class amateur exam of the time. I did 2nd Phone in the late 70's and there was tube, transistor, RTL and TTL logic theory, and 'complete the schematic' type questions but less of that and more general types of engineering and circuit theory, AC/DC theory, RF and transmission lines and most of it involving Electronic Math. Trig, Vectors, no Smith charts or Calculus. Very little of it had anything to do with tubes specifically. The rest was FCC parts. It was said at the time, that it was more like the Advanced Ham ticket. I got my Advanced a year or two before, and I agree the technology level was equivalent and it was about 200 questions or so. Later when I did the Extra, (90's) there were questions well beyond the 2nd Phone but only 25 of them! The code test and the noise floor equations made me strain. I wish the bandwidth and modulation questions were on the Technician class test though. ------------ Yep, the solid state and basic computer theory were there too, but I was surprised that they used a schematic of an RF tube amp for diagnostics purposes. I was sure that they were going to use solid state equipment for diagnosis. I was wrong. As it turned out, tubes are always easier for me to figure out, so it ended up being a plus for me. The Advanced Class amateur license test was definitely the pinnacle of amateur radio technical testing, but I didn't feel it was up to the 2nd Phone test that I took for the General. In fact, I even found a few mistakes in the Advanced test. The Extra Class test (I took it in 1985) did include a question or two that required some trig, but I figured out the answer in my head before finishing the equation. It was obvious that the conjugate impedance was going to be capacitive. There was only one answer with a -j, so it was obvious that that would be the correct answer. Ed, NM2K |
