Re [Elecraft] K2 Resistor Question...
Hi David I do not see any problem, at least for R6, 7 and 8. You have an M 10 db attenuator and mesuring R6 or R8 you have 100 ohmswith 168 ohms in parallel. So the result should be 62.68 ohms on you DMM! R7 is 68 ohms with 200 ohms in parallel so you should have 50.74 ohms! So as the series of resistors are 5% tolerance what you got on your DMM is largely within this parameter! 73 regards F5UL/Bob ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 20 wpm OT
In a message dated 7/7/07 12:10:10 AM Eastern Daylight Time, [EMAIL PROTECTED] writes: I remind people that before the FCC became involved, there was no test. No, that's not true. Mandatory testing for radio licenses in the USA began in 1912. The FCC began about 1934. 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 QA 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
[Elecraft] K2 - KBT2 and solar power?
After using my K2 for its first Field Day, I now see a reason to install the KBT2 built-in battery. But, I particularly liked using solar power -- a 10-watt panel running through Don Brown's solar charge controller to a gel-cell battery in parallel with the radio while operating. Worked really well. Can something like that be done with the KBT2? The charge controller cuts off the solar panel when the battery gets to about 14 volts, but it needs to be near the battery to sense the voltage correctly. The solar panel can generate 20 volts at 1/2 amp -- what happens if this particular charge controller is plugged in between the K2+KBT2 and the solar panel? My guess is that the controller would keep the voltage down to 14 volts, but would never see the battery as fully charged. Do the diode and resistor in the KBT2 prevent overcharging? It sounds less controlled than the KBT2 is designed for. Anyone have experience with this?

Re: [Elecraft] K2 - KBT2 and solar power?
Hi The resistor and diode in the KBT2 limit the charge current to the internal battery but really do not prevent overcharging. If the input voltage to the K2 id about .2-.3 volts greater than the float charge value of the battery (13.8V) then all is well but if the voltage is higher you may overcharge the battery. The switch off point on my solar controller is set at 14.1 volts. With the duty cycle the average voltage to the battery will be about 13.8 volts or equal to the float charge rating of the battery. If the charge controller is connected to the K2 power input the diode drop in the battery charging circuit would lower the voltage switching point to the battery and the battery will not come up to a full charge. There are two ways to solve this problem. The best way is to install a fused connector on the back of the K2 that connects directly to the battery terminals. The solar controller would connect to this connector when using a solar panel to charge the battery. A power supply will still operate the K2 and charge the battery through the normal power input when not using the solar panel. The other way to solve the problem is to increase the controller switching point to about 14.5 volts by installing a 220K resistor at R9. I have not tried this but should work. The controller would plug directly into the K2 power connector to charge the battery. If you use this method then the controller should not be connected directly to the battery.

Re: [Elecraft] K2 Resistor Question...
Thanks to David, Don and Gary for making me feel better this morning about my resistors. I have been testing each prior to installation but when came to that group, got lazy and decided to only check them AFTER installation...which then made me wish I hadn't gotten lazy!!! Great object lesson here...don't take shortcuts! It just didn't seem possible that measuring on the leads directly on either side of the component that there would be that much resistance draw after mounting...but the fact that it was so uniform on both of them, plus the third one (68 ohm) being down that much as well made me curious! I really appreciate the explanations...that's why I joined this reflector and am assembling the K2..to learn! I'm already dreading the empty feeling that will come about when it's done and I don't have it to retreat to in the evenings! But, I've got the SSB board setting in a box to assemble, and keep pouring over the options on the website, so as long as the XYL doesn't completely pull the purse strings shut, I'll be able to keep on building! Thanks. Quoting David F. Reed [EMAIL PROTECTED]: David, I am not sure how best to put this... Imagine you put a resistor of infinite value in parallel with your 100 ohm resistor and measured it at the ends of the 100 ohm resistor; of course, you would see the 100 ohms; what if the two resistors were 100 ohms each? well, being in parallel, you would see 50 ohms; if you put a 0 ohm resistor in parallel with the 100 ohm, what would you see? so anything with some resistance to it, a resistor, a trace, a relay coil, will affect the resistance you measure. A nice mental exercise you can do with a handful of resistors is to tack solder them together into a cube, and start measuring across different points; maybe even make it simple, and do just a square first (4 resistors); you might start to develop some intuition about how this works. try it with same value resistors first... I think you will find your resistors are fine; when you get to a test sequence in the manual, you will see they tell you what to look for in resistance that is quite different and that this intuition gained will help you feel more comfortable. Alternatively, if you are more accustomed to math, you might just learn some of the associated applications of Ohm's law, or do both what the heck... [EMAIL PROTECTED] wrote: R6 and R8 are both listed as 100 ohm resistors (BRN-BLK-BRN), but after installation, both show 61.6 ohms on three different DMM's..while R7 which is a 68 ohm resistor is showing 50.1 I recognize all of them read slightly lower than their listed values...but these seemed at such wide variance I didn't want to continue until I knew whether I should be replacing them or not. These three resistors all form a U around relay K12...so I didn't know if the relay would be sucking down my readings...but I'm placing the probe on the resistor wire on either side of the body of the resistor...so I can't see how something else could be causing that great of a difference the rest of the circuit that is in parallel with the resistor is responsible for that variation. Another identical 100 ohm resister still in the paper ladder to be installed later in the sequence is giving me a 97 ohm reading... And if you removed the ones you already soldered in, they would measure close to the same 100 ohms (or 97 in your case. Any advice would be appreciated.

Re: [Elecraft] K2 - KBT2 and solar power?
While Don Brown has offered an alternative to increase the voltage of the controller, I would not recommend doing it that way - what you end up with is a solar controller that is specifically modified to use with the K2 only. I would want the solar controller to work with any 12 volt Lead Acid battery and the charger modified for this K2 use would overcharge a battery connected in the normal way. If I did modify a controller to have a higher output voltage I would mark it in BIG BOLD letters to serve as a caution against connecting it directly to a battery - I know such mistakes do happen. Don B. did say that the direct battery connection inside the K2 is the best method, and I fully support that. 73, Don W3FPR [EMAIL PROTECTED] wrote: SNIP...

Fw: [Elecraft] Hate the word HAM
I have a different perspective on the code requirement... I was really into Heath Kits when I was in h.s. (~1977). I _so_ wanted to get my Novice license; however, I didn't have an Elmer. I would look at the Heath catalog dreaming that some day I would. I tried learning the code by myself (as I had to learn it for Boy Scouts anyway (it was a first class requirement back then). The problem was that I learned it wrong. Without mentoring, I learned it via mental look-up-lists. I am still struggling with that today. When the code requirement was reduced to 5wpm-- I was able to get my extra license and I have been very active in amateur radio and scouting (I am actually running a JOTA event for the Boston Minuteman Council this Oct.). There were a bunch of people that were just as I. Now I am seeing a big uptake in amateur activity with the dropping of the code requirement. Ironically, I am seeing more people get on CW. IMHO-- CW is more _popular_ now that there isn't a requirement. I _love_ the idea of CW! I wish I were more of an audible communicator (I am very visual)-- it is just something my brain doesn't do very well and I struggle with it. I have one of those MFJ code practice appliances and I struggle 12wpm. I have vowed to master it (well at least 20wpm) just because I will not let it beat me! :) (:I am a stubborn Swede and the only way to get me to do something is to tell me I can't do it:) Youth today have too much on their plate to do what we did. My daughter had a blast at field day! There were 3 other teenagers there and they ran the GOTA station. She made 96 contacts and was psyched to take the test. Now back in the day-2-day, I can't get her to spend the 4h coaching enough to take the exam. They will not invest the time to get on the air as it is too easy to get involved with other things that give immediate gratification, e.g., photography, web design, programming, gaming, etc. I have had some moderate success getting some scouts interested in radio enough to take the test (but I have to bring it to them rather then them being motivated enough to seek out an exam).

Re: [Elecraft] K2 - KBT2 and solar power?
Don and Don are more qualifued than I am to answer this, and they already have, but I wanted to point out another option. With the KBT2, the 10W panel may be too big, and you can use a 5W solar panel and the KBT2 without a charge controller *if* the K2 is on and the current draw is about the same as the panel output. For example, the Northern Tool flexible folding panel for $40 puts out 340ma at noon, and my K2 with all options (DSP) on, pulls 320ma. I monitor the battery voltage and plug in the panel directly to the extra battery connection Don mentioned. When the K2 is off or if I want to charge the battery and turn off options, I use Don's controller inline. Result: after my FD operation 1B2B/WNY (we were driving to Canada from Syracuse) I found my KBT2 fully charged. 73, Leigh/WA5ZNU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Another suggestion in regards to providing the fused connection to the KBT2, as recommended by Don Wilhelm, is that you make the DC input connector a 2.5mm connector to differentiate it from the 2.1mm power input jack on the K2. As Don pointed out to me, it may do no harm (or it might) if the charger (solar panel controller) was plugged into the supply jack or supply voltage applied to the direct connect, but it will keep them straight and separate. I've tried plugging my Smart Charger in blind a few times and it does help in getting it into the right connector. BTW - would you mind telling me what the 10w panel and controller costs were?

[Elecraft] K3 Panadaptor Question
I was thinking (dangerous activity and very difficult at my age) about the K3 Panadaptor/Band Scope. I realize the Panadaptor is downstream (2008?) and these questions may have already been broached and are in the archives but ... 1) I wonder if it would be possible to mount the Panadaptor as a flip-up device on the top of the K3 cabinet? In use it would be up and in my line-of-sight; down, the face would be protected and out of the way. 2) Are there plans to allow the decoded PSK/RTTY/CW output to be routed to the Panadaptor screen (while turning off the band activity display of course)? 3) Similarly, will it be possible to route the echo output from the (mini Elecraft) keyboard (K3KBD?) to the Panadaptor screen? Split screen between input/output. Questions (2) and (3) are partially in deference to the average K3 buyer who, I suspect, last saw the age of 25 several decades ago. Mostly I am thinking more characters with bigger fonts. MikeW5FTD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] RE: K2 - KBT2 and solar power
Thanks for all the responses. I guess I could run a battery charging cable out one of the unused holes -- not perfect, but certainly usable. (I'm not willing to drill another hole). It seems to make the diode-resistor arrangement in the KBT2 irrelevant, though, particularly since my normal power supply is a gel-cell. My solar panel is the experimenter/budget 10 watt panel from Connecticut Solar. It's very nice -- gives over 15 volts even in shade, and folds up in a zippered nylon cover. It was about $100. The charge controller is a nifty little kit from Don Brown, about $25, I think. It's not a way to save on electric bills, but it is interesting and fun.

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: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 coming next week, have questions...
Hi, I got on this list a few weeks ago and asked about K2s. I have a used one coming with a lot of options, but 100 watts NOT being one of them. It is CW only, which is fine, as I am about 95% CW these days. It is an older one. The SN is in the 22xx region, but has all the updates. I downloaded the manual: K2manRevC.pdf. Are there any other docs I should download? One of the first options would be the KPA100. But I wonder if there are other amplifier options I could use at home. Even 30 or 40 watts would make a big difference. I kind of want to keep the rig lower power for portable work. Full QSK is definitely important. I'll probably end up using the KPA100 anyway, especially if it separates easily. What is the typical build time for the KPA100? It already has the KAT1 internal antenna tuner. I don't know how that affects the KPA100 upgrade. Obviously, it has to be before the amplifier. I have heard the KDSP2 option is not needed. Of course opinions vary. My main concern is having enough audio to drive headphones. I have the Heil Quiet Phones and some cheap Koss UR/29s. I use the Heil with my Pro 2 and the Koss with my FlexRadio SDR-1000. The choice appears to be an impedance matching issue. The Koss's won't put out enough audio from the Pro 2. I have a moderate hearing loss, but don't use my hearing aids with headphones due to feed back. I posed this question a few weeks ago, but don't remember the responses. 73, Steve N6VL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] 13 wpm (was 20 wpm)
Yes, I remember Mr. Cigar out of NYC very well. In late 1966 (or Jan 1967?) I approached the NYC Federal Bldg with my mom (I was 14). There was a female guard/receptionist just inside the entrance. She looked at me, my mom, and said, Here for your FCC test? and told us the floor - which I forget now. It was a long elevator ride up and the sissors-gated pathway finally opened up. The place was old and filthy with long hallways (at least that's how I remember it). Walking in, there he was (others had warned me). There was a row of desks along the wall opposite from the windows (which had 100 years of filth on them). I was seated at the first desk with a straight key. I copied what was sent and after some waiting, got the nod. Then it was my turn to send. I touched the heavily patina-ed key, but it didn't send anything. I mentioned this and was moved down a few desks. I touched that key and whomever was there before me, had it set to one molecule spacing. Just breathing on it caused it to key. I mentioned this (again) but now was told, This is the standard key. Either send on it or you fail. I grabbed the knurled, brass set screws and, with all of my might, tried to loosen it up. Nothing. I tried again. Nothing. Mr. F was getting annoyed. I gave it one last try. POP! the thing loosed up a mile wide. He said, SEND. So I starting sending the text. The gap must have been 1/4 inch..I was REALLY pounding the brass and it sound like I was hammering a nail. I clearly recall EVERYBODY in the room stopping what they were doing and looking at me. Gawd! But I kept sending. Mr. F was not happy with my L's and told me so. It was the spacing, I said. He said, Let me hear 5 L's. UGH! I managed to get them out and he said OK. I'm sure I was sweating to death. Looking around, everybody was still starring at me but they soon went back to their exams when they saw that I was finally done bothering them. A day I shall never forget. Of course, after passing (on my first try), my mom swung by Harrison Radio.

(you do have the KSB2 plugged in correctly do you not?). The only other signal that must be present is the TX VFO which should have at least 70 mV RF on U10 pin 6.

Re: [Elecraft] 20 WPM
I had to get a new 2nd Telegraph a few years back and the FCC gave me 20 WPM credit -- not for having had a prior 2nd Telegraph but for having had an Amateur Extra since before 1980-something! But the FCC accepting a ham 20 wpm test result, even one from the 1950s, as qualifying one for the Commercial Radiotelegraph license Morse exam was a really bad joke. The real commercial second class code exam required receiving and *sending* at least one minute of perfect copy in a five-minute session at 20 wpm plain language *and* 16 wpm random code groups. That 16 wpm random code group test is for most folks far far harder than the plain language test. In five minutes you hear 400 random characters, including numbers and punctuation (count as two characters). You can flunk the random test if you have as few as six copy errors out of 400, if the errors are spread out such that you have less than 80 consecutive characters correct. Been there, done that!

[Elecraft] Ham Radio Nostalgia and Silicon Valley
All this reminiscing reminds me of an excellent book I recently finished, Bill Dave by Michael Malone. It's the story of Bill Hewlett and Dave Packard, founders of Hewlett-Packard. It's so well written I nearly read all 400 pages in one sitting and because I was privileged to work there even while Bill and Dave were still in charge. The first chapter has numerous references to ham radio and the role it played in shaping the lives of many early electronics pioneers. The only call I know for sure was Dave Packard's (9DRV during his boyhood in Pueblo, Colorado). http://hamgallery.com/qsl/Antique/USA/Colorado/9drv.htm Some others mentioned in the first chapter are: Fred Terman, head of Stanford's Comm. Lab Bill Hewlett, co-founder of HP Lee de Forest, triode tube inventor William Shockley, co-inventor of transistor Vannevar Bush, later MIT president Charlie Litton, Litton Industries founder Herbert Hoover, Jr. etc, etc. In retrospect, ham radio was the first Silicon Valley boom, and, because the cost of entry was so low and the technology so simple, it was more open to newcomers and technology amateurs than any that followed up until the dot-com boom almost a century later. And, like the latter, ham radio also showed many of the characteristics of a bubble. In the beginning, it was filled with maverick characters, overnight sensations, quick fortunes, and starry-eyed young players. Fred Terman would recall the happy days of running around the residential streets of Palo Alto, looking for the telltale antenna towers in backyards and knocking on the front door, knowing that a kindred spirit lived inside.

Re: [Elecraft] 20 WPM
I took my Novice exam in late 1952 and General in early '53 in NYC. The descriptions of the venue are certainly accurate! The exams I remember did either require drawing circuits or fixing pre-drawn ones. Fortunately the code was never a problem for me and I was even congratulated, although grudgingly, for perfect 5 min copy by He Who Was the FCC God. I took my Extra, 2nd telegraph and first 'phone in St. Louis on one of the visits from the KC office. CW still my favorite mode and if they ever should decide to shut it down they'll have to pry my key from my cold dead hands, to paraphrase some other zealot.

Re: [Elecraft] RF Probe again
Gary, You should have signal at U10 pin 1 but you don't - you had a signal at the BFO output if I recall correctly, so something is broken between those two points.

Set the K2 to TUNE and recheck to be certain you have RF at the following points (in order): U11 pin 6 Q24 gate TP2 D36 anode (small fragile glass diode on the bottom of the board) D36 cathode J11 pin 12 J11 pin 7 U10 pin 1 That is the entire path between the BFO and the transmit mixer input, and you should be able to locate the point where the signal disappears. 73, Don W3FPR Gary Montalbine wrote: Don Wilhelm wrote: Gary does not work weekends, and you can likely have it isolated by then.

[Elecraft] Elecraft CW Net Announcement
Good Evening, I think summer has officially arrived in Oregon. No rain for almost a week and the temperatures are reaching the 90s in the early afternoon. After dusk the temperature drops into the 50s. On the 4th of July I hiked up the mountain to an open area with a panoramic view. I could see the fireworks from many communities over a range of 270 degrees. However, the wind was at 40 mph and the temperature was dropping quickly. I had a coat and hat on and dug out my gloves before I was comfortable. Since most of the cities within my view had no public displays I was treated to the many families shooting them off. Banks, a nearby town, was the only community with fireworks other than Vancouver, Washington. Only the highest shots from Vancouver were visible to me but I could hear them quite easily. Yesterday I worked into Oklahoma on 20 meters. We chatted for an hour but the band seemed weak. There was a little QSB and some QRN from summer storms but the band was just not very strong. Today I am hoping to catch the folks in New Mexico running the N5C special event station commemorating the UFO crash of '47. That will be a good test of twenty meters because they'll be running voice. Last night I was able to check in to the MARS nets on 75 meters but it took a couple tries. Being at the bottom of the sunspot cycle is not helping voice operations. MT63 worked its magic as it usually does. Some folks forego voice check ins and simply use this digital mode to announce their presence. A little after noon yesterday I heard some odd squeaking in the kitchen. It sounded like an angry hummingbird. When I got there I found a male Allen's hummingbird in attack display (or should that be annoyed display?) up in the skylight. Other than cleaning out the cobwebs he was not making much headway so I got my ladder. After chasing him around a little with my hands he settled down and stayed in one spot. This allowed me to catch him. He calmed down as the light went away from my closing palms. He sat on one hand as I navigated down the ladder without the use of my hands. I got him well away from the house and opened up my hands. He gave me a funny look, sat for a couple of seconds, and then flew to a nearby fir tree. He sat there looking at me while recovering his wind. This is the third time in my life I've held a hummingbird. They feel like one is holding a running electric motor!

Re: [Elecraft] RF Probe again
Gary, Possibly Q24 could need replaced, but it is too quick to judge. Certainly V ALC is not up to the normal DC level - BTW, that listed voltage is nominal for a setting of 5 watts out with the K2 actually delivering 5 watts. Since you have no power out, the voltage on V ALC should be quite a bit higher. If the K2 senses no ouput, the V ALC voltage should increase in an effort to increase the power - that is not happening in your case. V ALC comes from the Control Board - the emitter of Q8 drives that signal. Check the 2 capacitors added on the back of the Control Board (this circuit deals with the keying waveshape control). With the information you have provided so far, Control Board U10A, Q8 and their associated components are the prime suspects. 73, Don W3FPR Gary Montalbine wrote: Don Wilhelm wrote: Gary, You should have signal at U10 pin 1 but you don't - you had a signal at the BFO output if I recall correctly, so something is broken between those two points.

I was sort of rattled going for my Extra and got to the FCC several hours before the exam. The examiner [nice but likely expecting a little more maturity than the 16 yr old possessed] said, I'm giving the 2d Telegraph. Fill out the app and take the code. If you pass, I'll give you credit for the 20 for the Extra this afternoon. I did, I passed, and he did. He also told me I had nothing to lose by taking the 2d written. I passed -- exactly. I didn't get credit for that in the afternoon, but I passed the Extra written by a slightly larger margin. Apparently the FCC was enamored with the Colpitts oscillator in those days ... I too had to draw the circuit, and then answer a couple of questions about its characteristics. Here's a tip, BTW ... many can write faster when copying CW by using longhand. I'm a genetic southpaw who was required to learn to write right-handed in public school. As a result, I couldn't write legibly with either hand and still can't. The nice examiner looked at my paper, said, Why don't you print this out below each line for me, I did, and he passed me.

She later married a doctor with no connection to ham radio! g The popular appellation of Uncle Charlie for the FCC referred to him although he never had any enforcement function in his long career with the FCC. In late 1966 (or Jan 1967?) I approached the NYC Federal Bldg with my mom (I was 14). There was a female guard/receptionist just inside the entrance. She looked at me, my mom, and said, Here for your FCC test? and told us the floor - which I forget now. My last excursion to 641 Washington Street was a week before Thanksgiving 1967 to pick up my travel orders to report to duty at the San Francisco office, and I didn't remember a guard. I had been in that building many times between 1952 and 1967, not always to go to the FCC - a close family friend and my mentor to join the Federal service was a claims examiner at the Department of Labor and I would occasionally drop by to let her take me to lunch and bend my ear about the benefits of the Federal civil service! Ten years after I graduated as an EE I took her advice! It was a long elevator ride up and the sissors-gated pathway finally opened up. The place was old and filthy with long hallways (at least that's how I remember it). In the 70s the rats finally conquered the building, and all the Federal offices moved out. The building was gutted and fumigated, sold on the private market, and AFAIK expensive condo lofts were built inside the old shell. I clearly recall EVERYBODY in the room stopping what they were doing and looking at me. Gawd! But I kept sending. Mr. F was not happy with my L's and told me so. It was the spacing, I said. He said, Let me hear 5 L's. UGH! I managed to get them out and he said OK. I'm sure I was sweating to death. Looking around, everybody was still starring at me but they soon went back to their exams when they saw that I was finally done bothering them. Very classic Charliehe would also take his phones off, stroll to the window, and listen to the sending by copying the key clicks by ear! A day I shall never forget. Of course, after passing (on my first try), my mom swung by Harrison Radio. Wow Didn't we all !! We used to remark that the double entrance doors of that store - necessary to keep out winter weather - were of course arranged in push-pull (what else). I got my first receiver there - a well-used National HRO Jr. Although it was the top of the line in ham gear for its pre-WW-II time, it couldn't hold a candle to any of today's Elecrafts.

My Elmers call sign was 2CGI. His name was actually Elmer Carter. I still have his QSL and on it as a receiver it says 1 MO low loss, Ant. 4-wire fan. Under Transmitter there's a place for watts and Volts on Plate. Note on the bottom reads Always Glad to QSR No Messages Die Hr., We Always QSL, Do U? I can vaguely remember some of his equipment which was all homebrew and tubes and wires mounted on I think maybe bakelite. My apologies for getting off topic of the forum but thought some of you ol'timers might find it interesting - and may have contacted him. Cheers, Jim/k2hn Building a website is a piece of cake.

[Elecraft] Cut off date for K3 options?
On the Shipping Status page it states /At your option we will ship your K3 with the standard 5 PPM TCXO and then ship you the TCXO3-1 when it is ready - no additional shipping charge. /Should I have been contacted to ask what my option will be? Also, is there a cut off date for ordering (and perhaps swapping) extra options, e.g. filters? There seems to be a lack of information/instructions for those of us with K3s on order! I haven't received a receipt for the deposit either... But get receive an acknowledgement. I assume there will be an invoice for the final amount arriving soon... 73 Dave, G4AON/ / ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
