Re: [AMRadio] RE: Average Age etc..
Here goes - don't tell this one often, but it is true. I am 58 (not the story), and took my general test in December of 1964 at the Federal Building in Cleveland. I was pacing in the hallway with about 50 other people waiting for the examiner to let us in. As we were milling around an older fellow seemed to stumble into me and instead of rebounding with the apologies he kept sliding down my chest then onto the floor. His glasses broke and there was a small pool of blood. Others quickly gathered and there was a doctor who took over the scene. The examiner came out and ushered us all into the room. Passed the code -flunked the theory (retook it in February and passed both). According to the staff in the building the gentleman apparently did not survive.

How many more of the Channel 90 bunch, other than Jim/K5BAI are 70+? 50, eh? Well, you've only got -a- year on me, Brian :-) I'll be 49 (I can hear the scuffaws, and the throat clearings, now!) in December of this year. And, you know.. in this thread, I need to tell this story, about the last time the FCC was at Brooks AFB... I had gotten my Novice from (and I can't believe I don't remember his name - but I can see his face, and know where he and his wife live) the guy who was giving Ham Radio Classes, via the San Antonio Radio Club. He was an Advanced, and his wife was a General. After the first class (once a week, and thanks, Dad, for sending me!) I went home and got out my old J-38 on a peice of 1x6 that I built as a Cub Scout project, when I was 8 years old. Hmmm... seems to me that's also the time I was introduced to threaded screws, vs using nails on lumber. You think it was in preservation of the J-38? HA) Got Dad interested in helping me build the code practice oscillator, and started going through what I remembered from learning the code some 18 years prior. After the next 'class', I told the code instructor I wanted to take the Novice test. We set up for the following Friday night, I went over, he and his wife administered the test, and I PASSED! I missed 'one' question on the CW test (5wpm) and 2 on the written test, and that was only because a couple of rules had changed on the frequency allocations less than a year prior. I don't remember exactly, but it was something to do with the novice sub-band on 15m, I think (at least that was -one- of the questions, and I didn't care about 15m... I wanted to work 40m CW, just like my ol' man!) So, the wait was on. And, it was 3 weeks to the day, on Friday, when I got the ticket from the FCC - KA5THB. In the mean time, I had gone out and created an operating position. National NCX-3, borrowed/handed down from Dad (then W5OMR -R.I.P.). After a frustrating night of calling CQ and not getting any answers on the 40m Novice frequency of 7.110, I started tuning around... and listened to someone called 'ME'! I got him at a comfortable tone, and answered. It was W5OMR (at a different location), but when he came back, he wasn't the perfect 800Hz he had been, before. That's when we discovered that the National NCX-3 didn't have a 'shift' for CW. So, my solution to that was, use a different receiver and a TR relay. Out comes the Heathkit Twins... Commanche and Cheyanne, mobile radio. We're in business. That was February of 1984. That Fall, in September of 1984, was the last time the FCC came to San Antonio. I took the General test, CW and Written. Nervous as I could be, we were seated in a -huge- auditorium, with no good way to write on a table or desk-top, and the CW test was given via 2 big speakers on the stage. Echo, reverberation, acoustical bouncing, etc... I managed to miss -1- too many, BUT, I *ACED* the written test. Back then, going from Novice to Technician, meant passing merely the General Written Test. Got that. General Class? No.. I missed 1 too many questions on the 13wpm test. Drat. When I got home, dad asked "Well, is it this? (with a hand stuck out for a congratulatory hand-shake) or This?" (and he doubled up his fist, with the same hand). I said... 'somewhere inbetween'. He looked confused and I explained what happened. After consternation, he finally said "well, at least you're moving up". :-) Indeed! the follow January, the Austin Radio Club had their very first VE session. Brian Battles, N5BB, Dave Wall/NV5I signed my Certificate of Successful Completion Exam, for having passed the 20wpm code test. I only -went- there for the code test. They handed me the advanced test material (which I had never looked at prior) and got half of those right, simply by -guessing-. Got the upgrade to General, by passing the 20wpm code test. To this day, I've never taken the 'official' 13wpm test again. I kept KA5THB, from Novice, to Technician, to Advanced (1988, I believe with Danny/then N5CED now KE5ZS), to Extra (with Randy, then WA1GZV and Jerry, then KG5EJ (sk)) in 1992, and didn't change calls until the two year grace period expired on upgrading calls for W5OMR (who went SK on me, in September of 1988).

Kansas City the day before Thanksgiving way back when. I show up and only one inspector was there, no one else. They only give the test on certain days but because I had come from Springfield (200 mile away) and he wanted company I guess, he gave me the test, graded it and I went home with a First Class License.

Re: [AMRadio] RE: Average Age etc..
That was interesting reading Ken. Up until you started with high power, I was with you. I licensed in late 1955 and got on 80 meter CW as a Novice about 6 months later. My parents would not let me order anything until I knew I had passed the test. ARC equipment followed for about a year and a half. I did not have a high power AM signal until 1992 when I found this Globe King 500A. I do wish I had my old Novice license, but I know that is long gone. The best I can do is a QSL card from my elmer dated early 1957. You have made me wonder if anyone here has a QSL from KN5MDQ or K5MDQ, especially the Novice one. I would like to find a copy.

I was real lucky in that when I got my commercial license (before my general ham ticket), the questions were all about tube stuff I was interested in building. The questions were actually very interesting (and easy)! The general test was also easy (at that time). I would get about a 50% on the current extra test...

Since we are going down memory lane, I thought I would put in my 2 cents worth: http://w2dtc.com/w2dtc-radio-history-page.htm 73, Ken W2DTC __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
Re: [AMRadio] RE: Average Age etc..
I gotta get in here, too. I turned 70 yesterday and my next project, if I ever get the time, is to recreate my old P-P 6L6 Novice rig and PS. I have all the parts ready to go, including the exact same power supply trannies that I got from an old radio store. BTW, If anyone had my original rig or PS or any parts thereof, I will be more that happy to buy them from you. That rig was sold in the early 60s at I believe, the Shelby hamfest. The buyer was one Bobby Dees, but I have never been able to locate him. If it is still intact, you will know it because it is built on a sheet metal chassis 8 X 12 X 3. There were 2 chassis, with the PS on the bottom and the RF deck on top, separated by Erector Set "L" shaped girders. The chassis were made of heat duct shgeet metal and look like the old furnace duct work. 73 and keep 'em lit!

Re: [AMRadio] RE: Average Age etc..
Central Electronics 100V and 200V (50's stuff) transmitters had no transmitter tuning on the front panel. Once you aligned them properly, there was no dip the dipper or peak the peaker or adjust the grid or diddle with the buffer, etc. Pete, wa2cwa On Mon, 23 Jul 2007 18:41:48 -0500 "Rick Brashear" <[EMAIL PROTECTED]> writes: > Yep!

RE: [AMRadio] RE: Average Age etc..
Yep! You're right, Ron. I know there was at least one schematic that had to be drawn and you certainly had to have a working knowledge of current flow and basic circuit design. I guess there were more questions then relating to the type of equipment we used in those days. When I got my General there was no such thing as a "no tune" transmitter or amplifier. You had to know when, how and why to dip! I guess progress has moved the test beyond the need for such knowledge, but I can't help but believe it was a good thing to know then and would be a good thing to know now. Of course, I'm an old coot and live in the past. Rick/K5IAR Hey! I'm 62 but whose counting? I seem to recall that when I upgraded my Novice license I actually had to draw a Hartley oscillator and label the component values There were some multiple guess but they were rules etc as I recall... K3PID ( was KN3PID at the time..)
