![]() QST for July 1960, page 54. "FCC Written Exam Procedure Changing" . This article describes the new FCC answer sheet that will go into use "in a few months". It shows the new answer sheet and describes how the "draw a diagram" questions will be replaced by questions about a diagram, such as "what should be done to neutralize this circuit" Back in 1976 when I took the general written at the FCC field office, I remember that question was on it. The circuit looked a lot like an IF stage of an early transistor radio, which also used neutralization. So of the other questions required knowledge of a few different points of knowledge to get right. "You have a linear which uses B+ of 800V. For use with SSB, what is the max current your ampmeter on the finals will show?" You had to know 1) The FCC dictated input "plate" power for power limits for hams, 2) What the power limit was for SSB, 3) and how to factor in PEP averaging. And 4) how to calculate plate power. Knew everything except I was hazy on how to do #3. SSB voice is full of short bursts of higher power; however an analog amp meter's needle isn't responsive enough to show those spikes. So does this lack of response compensate for the FCC permitting SSB spikes up to 2KW, where CW is limited to 1KW (back then in the good 'ol days)? I made the choice to assume that this is true, and selected 1.25 amps for the answer. No way of knowing if I got it right or not, but I did pass (though by a thin margin of one excess correct answer). Embarrising as I was an EE student in college at the time. :-) I did ace the code test, which I had not expected to do so well on. Sometimes wonder if they gave me an all dit suffix (ISE) because I did so well on code.. :-) I did ace my restructured upgrade to "extra lite" a few years ago. |
