In between, radio licenses were issued by the Department of Commerce, the FRC, and IIRC the US Navy. > > I took my General test in the Federal Building in > Cleveland Ohio, the pressure was on and the test was > tough. > > I'm now studying the Q&A for the Extra exam, which is > a far cry from even the General back in the day. > I have ARRL License Manuals from 1948, 1951, 1954, 1962 and 1971. Comparing the study guides in them (which were reprints of the FCC-issued study guides) to the current license tests tells a somewhat different story. The old exams covered a few subjects in detail, but avoided lots of stuff. For example, the old exams wanted you to know oscillator and filter circuits, frequency tolerances of xtals and frequency meters, modulation percentages, harmonic, key-click and splatter reduction, and power supplies. But they all but ignored things like receivers, transceivers, RF exposure, satellites, repeaters, transmission lines, antennas, and much more. Looking at the old exams, it seems to me as if they were written to address particular problems they'd had with the amateur radio service in the past. Spurious signals? Toss in questions about pi-nets, lowpass filters, and neutralization. T8 and worse notes? Add questions about DC power supply design. Etc. By contrast, today's exams cover a much wider range of topics, but in less detail. Compare the two study guides side by side and see. btw, FCC introduced all-multiple-choice exams in 1961. But they didn't just toss out the old exams. Each exam site first used up their existing supply of "bluebook" exams. So depending where you took the test in the early 1960s, you could have gotten the old or the new. Now for my 20 wpm story. Before about 1974, you needed two years' experience as a General or higher before FCC would even let you try the Extra. You had to pass both the code and theory at the same exam session. No retries, no CSCEs, fail and you had 30 days wait before retesting. For a kid in school, exam opportunities were limited to the summer and the rare school holiday that wasn't a federal holiday. I upgraded from Novice/Tech to Advanced in the summer of 1968, age 14. I'd failed the 13 wpm on my first try because The FCC Examiner couldn't read my "Palmer-Method" longhand well enough, so I went home and taught myself to block-print at 30 wpm, came back later in the summer and passed. Two years later, on the first day I could legally try for the Extra, I was back at the FCC office in the old Custom House in Philadelphia - 2nd and Chestnut, 10th floor. August, 1970, the summer between 10th and 11th grades. There was quite a crowd there to take exams, both amateur and commercial. At 16 I was by far the youngest person there. At exactly 8 AM The Examiner came out and asked if anyone was there for 20 wpm. I was the only one. "This way, kid." Followed him into the big exam room with its code table, one-arm-bandit student desks, code test table, and locked file cabinets. The Examiner pointed to a chair at the Morse Code table for me. He then unlocked one of the file cabinets and brought out the code test machine, 'phones, and straight key, and set them up on the table. The code machine was a small unit that read holes in a specially punched paper tape. Speed was changed by swapping drive spindles of different diameters. He then unlocked a second cabinet and brought out a yellow legal pad and the punched paper tape for the code test machine. The Examiner got it all ready to go and then gave the same instructions I'd heard two years before: "Copy exactly what you hear. You have 5 minutes of code, I need to find 1 minute of correct, legible copy for you to pass. When the code stops put the pencil DOWN." I nodded that I understood and put on the 'phones. "Ready, kid?" I nodded again and he started the machine. I started right off, copying in big block letters. It seemed easier than copying W1AW or 3RN traffic - the code was strong and clear in the cans, no QRM or QRN. This was easy - I was getting every letter with little effort! The examiner watched me closely, but I ignored him. He came around the table and stared over my shoulder as I copied. Then he went over to the code machine and shut it off. I looked up, startled and a bit scared. Less than two minutes had passed - had I done something wrong? "That was easy, huh, kid?" asked The Examiner. "Uh, sort of" was all I could manage. "It should be" came the reply. "That was only 13 words per minute. Here's 20" And he quickly swapped drive spindles on the code machine and restarted it. Now the code came a lot faster and it was all I could do was copy it and hope for the best. I got the full 5 minute test and somewhere in there he found 100 consecutive legible characters. The sending and written tests were an anticlimax after all that, and I went home to wait for the license to show up in the mail after six weeks or so. I will never know if he simply forgot to change the drive speed or left it at 13 wpm intentionally to rattle a kid trying for the Extra. I do know that in those days one did not question The Examiner or his actions. I found out later that The Examiner was a ham named Joe Welsh, nicknamed Joe Squelch, who was a really nice guy outside the office, but who was All Business when it came to the exams. Doesn't seem like 37 years ago. 73 de Jim, N2EY ************************************** See what's free at http://www.aol.com. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Does anyone know if you can use the K1 backlight kit (K1BKLTKIT) to backlight
the Wilderness Radio KC2 display? dt . _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

David,
I'm pretty sure I didn't use a transflective LCD in the Wilderness KC2 design. You could check by trying to shine a light through it. If you can't see the light, it's strictly reflective and won't work with backlight. You could attempt to edge-light it with an LED aimed at the left or right edge of the glass. This won't look as good as backlighting but could make the display readable in the dark. 73, Wayne N6KR On Jul 7, 2007, at 11:00 AM, David Toepfer wrote: > Does anyone know if you can use the K1 backlight kit (K1BKLTKIT) to > backlight > the Wilderness Radio KC2 display? > --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The SF office used the big old Bohme machine - the one with the variable speed and the dial indicating the speed - well into the mid-70s. We used the little ones only for the distant-city exams. They were all replaced by tape recordings in the late 70s, when the sending tests for hams were abolished, making it easier for non-code-qualified examiners to give the code tests rather than detail an engineer or technician to do that. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
