On the other hand, if you have a bare K2 and plan to make it "Plug & Play Ready", then rev. G is something to consider since the headers will be installed permanently. --- - - - --- This redesign was initially undertaken to address "RF concerns" which recently kept one new K2 builder (a retired RF Engineer) from using our "Plug & Play Ready" assembly approach. In addressing this issue we added ground planes, re-routed the trace that replaces RF-W1, and shortened the signal paths on the UN-KNB2. We don't have the instruments necessary to determine whether there's a measurable improvement between rev. D and rev. G. If there were, it would likely only affect the two headers at the back of the RF board since they carry the un-amplified received signal. There is also a mechanical improvement in rev. G with the addition of an UN-KNB2 mounting hole. This might be an advantage if you operate portable/mobile. --- - - - --- There are some subtle changes that only affect assembly. Rev. G has fewer break-away tabs, a bottom silkscreen, and a built-in SIP connector separation aid. For our European customers, the rev. G UN-K60XV has a center ground pad for the Murata ceramic filter 40m narrow BPF mod. Lastly, there are a few things that we just wanted to improve upon in rev. D. All of the text is now right-side up, and the UN-K60XV no longer blocks the RF-L4 (80m BPF) adjustment slug. 73, Gary, KI4GGX K2 #4067 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

On Sunday 16 July 2006 at 2320 Ed (W0YK) wrote ... Gary, what is involved to upgrade? Just order the new Rev. G PCB blanks? Thanks, Ed - W0YK Hi Ed, Nice to hear from you. I recall that you were one of our earliest Plug & Play Ready builders. No doubt then, you have already built up your headers and are using them. In this case, you ought to get all of the parts to populate the rev. G board. This would be our rev. G Basic Header Kit. However, if you have a well stocked junk box and already have all of the required parts, then you might be able to get by with just the bare board. This would be our rev. G Bare Boards Only. Something else to consider is whether you purchased our printed Users Guide with your first order. If you did then you already have the neat color center-fold K2 un-module diagram. (It's far nicer when professionally printed, versus what an Ink-Jet printer can do.) If you didnt get it the first time, then you might want to consider getting the printed manual as well. This would be our rev. G Deluxe Header Kit. I hope this answers your question. Again, very nice to hear from you. 73, Gary, KI4GGX K2 #4067 P.S. The rev. G CAD images on our www.unpcbs.com/ website are now slightly out of date. A few days ago I changed our UN-K60XV making it more like the actual K60XV. These changes entailed swapping the copper layers so the ground-plane is on top, and the 4.7 pF cap is on the bottom. This subtle change makes the UN-K60XVs top silkscreen far less cluttered. Updated CAD images should be online within a few days. (I create these images manually, so they take a while to produce.) The next ones will have about 50% higher resolution. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2: Positive or Negative CW Keying? Again
Bernie; Winkey works just fine with the K2. Just hook it up. You should follow the connection diagram shown in the K2 manual, either connecting tip and the small ring together or using two 1N4148 diodes on each side to make sure the two circuits get shorted to ground at the same time. This eliminates the need to change the key menu setting when going to "hand key" mode, which Winkey needs. On Jul 16, 2006, at 7:40 PM, Bernard Gaffney wrote: Ignore last message -- an oops.

[Elecraft] Elecraft CW Report for July 16th & 17th, 2006
Good Evening Folks, The bands were a bit stingy this evening but that is how it goes sometimes. Unlike last week or the week before I did not hear Europe before the first net. My DX for the evening is Georgia :) That's OK, we had a good time. The weather here is warm but not like the reports I got from out East. There was more than one triple digit temperature report. Yesterday I spent walking around in the sun in mid 80 temperatures but we had a wind with low (40%) humidity levels. That made it comfortable. I spent the day drinking from my two liter bottles. The medical tents we visited refilled them as did our ARES tent supervisor. I've no idea how much water I consumed but it seemed to be enough because today I do not feel dehydrated; just stiff from walking and standing for so long. Tomorrow it is back to work for most of us. I'll be in downtown Portland where it gets much warmer than it does here. But, compared to you all, I feel lucky. With the mild temperatures and medium humidity summer is not so bad in Western Oregon. The reports from AB, OK, IN, and GA were not as nice. Only Rick in Palmer, Alaska had us all beat. Sounds very comfortable up there. However, I expect he has far more biting insects than me ;) That is one thing I do not miss from the Midwest. You can sit on your porch here and not be eaten alive. The lists => On 14050.50 kHz at 2257z: AL7N - Ed - AK KL7CW - Rick AK - KX1 - 798 QNI #50!!! VE6ITA - John - AB - K2 - 5384 QNI #15!!

W6BK - Dave - CA - K2 - 4910 QNI #5! KL7V/5 - Sam - OK - K2 - 3158 I think I have the above information correct but if not please email me. Thank you once again for your support. We will make it through the solar minimum and back to better propagation. It will not be long until the bands are filled again. I was promoting amateur radio while at the air show yesterday. It was surprising how many amateurs were listening to our health and welfare net while they were working in their booths making a little money. While my partner and I were scanning the crowd looking for children who looked lost a couple vendors walked up and introduced themselves. First by callsign and then by name. Not one of them broke our nets but they were monitoring our progress. The first lost child was around 1 PM. We had both parents to him in less than five minutes. The police and fire officials appreciated our eyes, ears, and comm skills very much. It makes my tired feet feel a bit better just knowing I could help.

It wasn't so much the formulas, some "crooks" were loading in the answers in the era of Dick Bash and the stolen Q&As. That eventually led to the public question pools. Eventually calculators were allowed if they were of the type that had no memory if they were turned off and on in the examiner's presence.

I took my Novice and Tech in the NY office in 1952, and then after college and grad school took the General (13 wpm code test was all I had to take) in the NY office in 1962. I took the Advanced written in 1968 in the San Francisco office just after it was restored to the "menu", and the Extra 20 wpm code and the written there in 1974. By that time I was a supervisor in that office so they had to get another supervisor to give me the test. After making sure that I did copy enough at 20 wpm to qualify, he started cranking up the speed on the machine behind my back, and lost me somewhere about 25!!

RE: [Elecraft] KPA100 Fan
Jim, The fact that you had the TPA parameter set to 11 degrees would explain the fan not coming on even with high heat sink temperatures - the firmware did not know just how hot the heat sink actually was because it was not properly calibrated. The temperature displayed in the TPA setting should always be the current temperature of the heat sink. The manual instructions indicating that it should be set to the ambient temperature is correct - provided that the heat sink has had enough time to aclimate to the surrounding temperature. If you need more proof of that, set the TPA parameter as described in the manual (after the KPA100 has been powered off for about 2 hours), and then transmit for a while. Afterwards, check the TPA parameter - it will have gone up to the temperature of the heat sink. IMHO, what the manual fails to make clear enough is the fact that the heat sink should be allowed to reach the temperature of the ambient air before you set the TPA parameter to the temperature of the ambient air. There is a temperature probe on the KPA100 - it is Q3 which is in contact with the heat sink. The firmware does the calculation of when to activate the fan based on your initial setting of the TPA parameter and the current temperature of the heat sink. I am not certain just what the trip point temperatures are - one could easily check by observing the TPA value at the time the fan turns on. It would be a good idea to check the TPA setting before using the KPA100 in high temperature environments. 73, Don W3FPR > -Original Message- > > Yesterday I participated with my K2/100 in the Pike Special Event station > here in Colorado Springs, Colorado.

[Elecraft] Legacy (WAS: Look what you've done to me!)
Sadly, Paul W. Klipsch is no longer with us and his company moves on into second generation. The famous Klipschorn corner horn is an amazing speaker. It was even more so in the 1950's when "Hi-Fi" was a new idea for most. His company will continue on, but like all companies it is no longer the same company with him gone. There may be others as great in the field. There may be others even better. But there won't be another Paul W. Klipsch. I had the privilege of working for Hewlett-Packard when "Bill" and "Dave" were still running the show personally. Recently I saw a piece about HP that showed how their private offices are still maintained at corporate Hq in Palo Alto, California just as I remember them. The office doors are always open, just as they were almost all the time when Bill and Dave ran the company. On Bill's desk was an assortment of coins. Employees leave them there. The coins are collected from time to time and given to charity. Like each and every one of us, people like them are unique. Like them, we each make our own contribution to our world in our own way. Some with things that are known around the world, some who change the world, some who only touch other lives quietly and whose names never become famous. Each one is amazing. It's what makes the world such an amazing place.

RE: [Elecraft] What should the power output of the K2 be?
The specified output of the K2 is at least 10 watts CW. The actual output varies with the band. It is a function of the overall transmitter path gain. It tends to peak about 40 meters, where most K2's will make 15 watts output, or very close to it. Up on 10 meters is where the overall gain is lowest and many K2's just barely make the specified 10 watts output. Since you're still getting familiar with your K2, here's a couple of things to remember: 1) The POWER control sets the "requested" power output. The K2 monitors the actual power output and adjusts the transmitter gain as needed for what you've requested. The control allows you to "request" any power up to 15 watts, but you can't get that much on all bands. 2) Because the POWER control circuitry is monitoring the power output to determine how much gain the transmitter circuits should have, the accuracy of the output power setting depends upon how accurately the K2 measures its output. A basic QRP K2 uses a simple RF voltmeter to monitor the output. It is highly-dependent upon an accurate, non-reactive 50-ohm load for good accuracy. Any significant SWR at the transmitter output will affect it, and the actual power output. The (KAT2, etc.) ATU's use a bridge circuit that is a little more accurate, but can still be thrown off by reactive terminations. 3) If you change the POWER control setting you have to transmit before the new power level takes effect, since the K2 must sense the output RF to tell how to adjust the circuits. That means that you may notice that the output is nearly zero when you hit the first dit or dah after turning the K2 on. It'll immediately jump up to whatever you have the control set for. The same is in reverse when you turn the power down. The first time you touch the key the power will still be up at the old higher level until there's RF for the circuit to sense. 3) The K2 is rated at 10 watts PEP on SSB, regardless of how much it will produce. That's because the distortion increases above 10 watts PEP in SSB mode. CW doesn't need a linear amp, so it's not an issue when you're pounding brass, but don't exceed 10 watts PEP on SSB on any band. 4) The Bargraph power display is in peak power, so it'll show flickers at the PEP peaks instead of the average power like most inexpensive external meters. That cause confusion sometimes when the opr notices that his external meter is wiggling around at 3 or 4 watts while his K2 shows 10 watt peaks on SSB. That's normal. The external meter is showing the average output, not the peak. Welcome to the K2-club John! I built mine in 2000. It's a FB rig. Ron AC7AC -Original Message- Hi all I have been having great fun with the K2 but I am wondering what the output should be? 10W or 15W? The Po control seems to indicate 15W should be possible. The PA alignment seems OK, or at least as per the manual, Po/current seems to match at the levels stated. But occasionally the built in detector seems to read a little higher than the Po is set to and the full scale setting of 15 only seems to yield 11w or so. As this is the only one I have built so far I am curious. Any guidance appreciated. John ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Weller WTCPT illuminated rocker switch
Finding the correct illuminated (neon lighted) rocker switch used in the Weller base units for their soldering stations, can be a daunting task. For the Weller WTCPS, WTCPT, WLC100, WPC300, EC1001, EC3000, early EC1002 models -- Weller used 2 primary suppliers for the illuminated (neon) power switch on these base units: C&K (ITT) and Carling (632 series) The Carling 632 series, can be found here (updated Carling web site) http://rocker-switches.carlingtech.com/illuminated-rocker-switch__37.asp Specifically the replacement part number appears to be: 632152-2B-JN http://www.carlingtech.com/pdf/CarlingSW_622_632.pdf This Carling switch is now as a solid color rocker or as a translucent solid rocker available in Blue, Green, Amber as well as Red. It is available in a wide range of lamp voltages from unballasted LED (3 VDC) to 250 V Neon Finding these switches for component replacement can be difficult. Some manufacturers only sell as an OEM component, will other suppliers eliminated the specific model, or require a special order with a quantity of 100 to 1,000 units. Specifications of the Weller illuminated (neon) rocker switch 120 VAC at 8 A SPST (On-None-Off) 120 VAC neon illumination .187" quick disconnects for ease of replacement with existing Weller wiring The Carling Switch current used by Weller has a nice rounded edge to the translucent rocker -- NKK and Cherry have a more rectangular, distinct edge. GC / Waldom Electronics now carried the exact Carling switch being used in current Weller production. GC Switch number: 35-696 SPST ON / OFF- RED CLEAR ROCKER As of July 16th, they reported 239 in stock ! Cost was about $ 2.50 (very reasonable for a blister pack part) Available at any electronics distributor or parts store - that carry CG/Waldom http://www.gcwaldom.com/home.html Two additional candidates for this illuminated rocker switch replacement are available from NKK Switch and Cherry. These suppliers have both 120 VAC (NA, Japan) and 240 VAC (EU, Asia) neon versions in their catalogs for these line voltages. The Cherry model comes in an Amber and Green color option. NKK CWSB21CACF (this is DPST version) - works by NOT using the "2a" contact (heat shrink insulation over QC plug). Allied Electronics part number: 870-0119 Allied & NKK did not list the SPST version in the catalog. I have personally used this part for replacing a defective switch in a PU120 based unit (WTCPS) - it works fine. Cherry LR Series ... LRA22H2BBRLN --- SPST Allied part number 908-0105 I have personally used this switch for replacing a defective switch. At 97 cents - it is a GREAT inexpensive buy http://www.cherrycorp.com/english/rockers/lr_rocker.htm Greg w9gb ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 CW Plug Wiring
Hi, A couple of questions: 1. Wondering how the CW plug for Hand or External keyer is wired? The K2 manual (pdf vers) doesn't indicate this directly, it just says the RING is used only for a Paddle. Therefore I assume one uses the TIP and GND for hand/external keying? Along of course with setting the appropriate options in the K2. Checked the archives back aways, didn't see anything on this. 2. With my TenTec Argo V model 516 (former rig), if I was in CW mode, keying the mic would also key the rig, without audio from the mic. Is this possible with the K2? Mainly used when tuning via an external tuner. (I do have the KSB2 module installed). K2 #5601 ETA: 21Jul2k6 72 de N8PVZ ---bernie __ Do You Yahoo!? Tired of spam? Yahoo!

[Elecraft] KX1 display flicker after activating SCAN mode?
I hit upon the scan mode by accident with my brand new KX1. Reading the manual it appears the memories are the scan boundaries. I've not set these, so they would be whatever default. I've noticed that while scanning, and even after scanning, the RF I hear is reduced from what I had heard before. And the display flickers, for example if it's displaying 2 it will flicker to 3. It keeps doing this until I power cycle the radio. Then the RF/signal goes back to normal, and the display works OK. Well, the decimal point seems to flicker once and awhile. I've double checked the solder joints, esp around the display and micro. Vibration does not cause the flicker either.

RE: [Elecraft] KPA100 Fan
I can't speak to the issue of the fan not coming on, but I can offer some experience with a hot heat sink. A few years ago I used my K2/100 to test the temperature compensation mods during which the heat sink became too hot to hold my hand on it. The internal air temperature of the K2 was around 50C/122F (monitored by a probe) with the fan running. No ill effects resulted. It's designed for that sort of thing. Ron AC7AC -Original Message- Hi, Yesterday I participated with my K2/100 in the Pike Special Event station here in Colorado Springs, Colorado. It was in observance of Zebulon Pike's bicentennial discovery of Pikes Peak. We were in a terrible location in a downtown valley with antenna restrictions imposed by the city Parks and Recreation department as the trees are older than the bicentennial. Propagation on 20 meters was very bad from our perspective. Now to my point. We were outside in 90 degree plus temps for over four hours. We were running PSK31 and SSB. PSK was kept below 25 watts. The fan on the KPA100 did not come on the entire time. I had it set for LoHi in the KPA100 menu. So it should have at least been on low speed all the time. The heat sink got very hotalmost too hot to touch. A couple time I though I smelled hot electronics. The PA HOT message never appeared. To add complications when I got home it worked as advertised in my cool basement. I did find the temperature calibration was set at 11 degrees centigrade (51 degrees f). Must have set it during the winter when the basement gets chilly. I reset it to 23 degrees centigrade. (71 f). Does anyone know of any mystery problems or other legacy fan problems with the KPA100? In a couple weeks I plan to disassemble it and have a look after I finish another K2 for an acquantance. The schematic nor circuit description does not address the fan itself as I can find. There is a "T sense" circuit but how the fan ties in is not shown as I can find. Your comments and thoughts will be very welcomed.

I only have the PDF version of the manual, where do I find it? or is there a standard method of doing it? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Elecraft CW Net Announcement
Good Morning, I am sorry this is late but I just got home from a very long day. I worked with the local ARES group at the Hillsboro Airshow. We found four lost children, assisted in a few medical problems, worked on fire watch, and generally stayed on our feet for about twelve hours. It was good to do a little community service and meet a lot of nice folks. This afternoon and evening (after I get a night's rest) we'll have two more nets and see how propagation treats us. I heard reports of 6 and 10 meters being open yesterday so 20 meters may be very good tomorrow (today?) too. That may mean we'll be working into Europe or it may mean North America will be easy copy. One can never tell. The sun looks a bit quiet but I've found that is not always an indicator of what may happen on the air. Simply getting on and calling CQ does wonders when the bands are supposedly dead. All it takes is one op to call and the others will find the band is not as dead as they first thought. Please join us: Sunday 2300z (Sunday 4pm PDT) 14050 kHz Monday 0200z (Sunday 7pm PDT) 7045 kHz Until tomorrow, Kevin.
