[Elecraft] Elecraft CW Net news
I am working on the ecn.visionseer.com website. I am trying to figure out a way to post a .xls (Excel spreadsheet) so it is accessible. I think I can post it as an href link and have the user right click and download it. Since I don't use Excel this has been translated from the original spreadsheet document. However, I know this works because of others using my translated files. Now to make it accessible via the web. I may, or may not, get it working tonight. I did get the roster, preamble, and notes updated. Disregard the times posted for ECN on the zerobeat site. They are wrong ECN is still at these times: Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0100z (Sunday 6 PM PDT) 7045 kHz Side note: Remember, while attempting to QNI ECN if you send while I am sending it is only so much QRM. Wait for the ? K and send your sign. Last week I was told there was an ** being sent while I was sending. I did hear a little but since I was sending I knew it was not for my ears. When I sent ** ? there was no response which only enhanced the notion that ** was QRM. There is often QRM during ECN but I work others around it. Please only send your call after the DE KD5ONS ? K.

RE: [Elecraft] CW rise time mod
I certainly did not notice it on K3 S/N 10, nor did anyone I worked on CW. But I seldom operate CW above 25 WPM. IIRC, it was a high speed operator who noticed the 'soft' keying, probably working at rates well above 25 WPM. Still, I made the change because, as the notes on the web page suggest, there will be the ability to adjust the characteristic using the MENU commands in the future. But that firmware will assume a particular hardware configuration, and I wanted my hardware to match what the firmware expects.

[Elecraft] K2 operation with internal battery
Jerry In reply to your question, I operate the K2 with internal battery and a charger connected all the time. Hearing concern about improper charging from many on the reflector, I searched out a power supply for this application. I operate the K2 with the battery on and on transmit power is taken from the battery. In receive or with K2 off, the battery charges. It works for me. Bob Lewis AA4PB wrote an article in 2001-5 QST about his K2 and battery along with his journey in understanding how to charge these SLA batteries. It is educational reading about charging mistakes. The power supply in the article can be built from a premade circuit board and your parts purchase from suppliers. Not a difficult build! Mine has been in use for 7 months and it is a joy to use. 73 Art VE9BP Arthur Gunn 74 Mill Bank Road Nasonworth NB E3C 2C6 [EMAIL PROTECTED] [EMAIL PROTECTED] (files >5mb) P 506.457.2020 F 506.457.2035 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 1.78 Firmware Power Output
Mike . . . Anyone with a new K3 would be well advised to be monitoring the reflector every day ... things are happening that quickly. Plus, knowing many others were having the same problem could have saved you a lot of time fooling around with "parameter possibilities." If you haven't had time to check out the website lately, you may also wish to avail yourself of the three factory hardware modifications that are available.

[Elecraft] Elecraft CW Net Announcement
Good Evening, I spent some time on the ECN website and got one thing changed. There is now a roster of all who have checked in over the years. I'll work on a few other parts of it now that I've got my tools working again. I have forgotten too much html code over the years and my partner trained in the arts is no longer available to help. Miss you Pat! But I will relearn from the books lying around the house. The sun finally broke through a few minutes ago. We have been getting more snow this week. I had six inches today to go with the other six from the last few days. I thought I was going to be rid of the last of the winter's snow when this storm started. I heard it is even falling in the valley. Good thing I have supplies because the natives have no clue how to drive when there is even a dusting of snow. Keeps the fender repair folks and the insurance companies in business! I was able to get on the air a little this week and call CQ. 20, 40, and 80 meters all elicited at least one contact. I am glad my antenna is still up and working after all the snow. I felt lonely so I got on the air. There are some folks out there willing to chat and I found them. I need to try 80 meters more often because I can then meet the locals :) Normally I work folks too far away to visit. Field Day plans are shaping up as well as QRP to the Field. Looks like I won't have to go too far to get on the air. FD will be about five miles from here. That is if I could drive right to it. However, the county has gated off those roads. I am thinking of just hiking over the 12 inch minus gravel road. I had better send this while I still have power and the phones are still working. Yesterday I lost power many times; today only a couple. I'll reset the blinking clocks when the snow decides to quit falling. The phone service has been intermittent over the last week and yesterday dropped out around 9 PM. It finally returned about an hour ago. The heavy, wet snow is not helping things. Even though my phone and power lines are underground they are not so further down the mountain. Most of the breaks occur within a mile before they go beneath the road. Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP help) Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0100z (Sunday 6 PM PDT) 7045 kHz Stay warm, Kevin.

Re: [Elecraft] CW rise time mod

Not my old brain. 73, John, W2GW K3 #384 - Original Message - From: "Lyle Johnson" <[EMAIL PROTECTED]> To: "Elecraft Reflector" Sent: Saturday, March 29, 2008 5:21 PM Subject: Re: [Elecraft] CW rise time mod Or do Rev A RF boards have a lower value for C222 than that shown on the schematic? Early production K3 RF boards have a 1 uF capacitor instead of a 0.1 uF capacitor installed at C222. Yes, the published schematics show a 0.1 uF capacitor. The effect of the larger capacitor is to increase the TX waveform rise time to about 8 ms instead of 5 ms. Rev B RF boards have the correct 0.1 uF value installed. Sometime during Rev A RF board production, the value installed on the board was changed from 1 uF to 0.1 uF. Surface mount ceramic capacitors are not marked with a value, so you cannot tell which you have by visual inspection. You can determine if you have a 1 uF rather than a 0.1 uF by: 1) Measuring the capacitance if you have a capacitance meter. 2) Looking at the Tx output RF envelope on an oscilloscope or "station monitor" scope. If the fall time and the rise time look very similar in duration, you have the 0.1 uF cap. If the rise time is about 50% longer than the fall time, you have the 1 uF capacitor. You don't need an oscilloscope with an accurate time base to make this comparative measurement. If your oscilloscope has a low bandwidth (2 to 10 MHz), use the 160 meter band. 3) If you are concerned that your unit may have the 1 uF capacitor and you have no way to determine it otherwise, you can just replace it with the 0.1 uF part and sleep better at night :-) If you don't change it, you will not damage anything. Your K3 will just have slightly softer keying and an upcoming firmware adjustment of the keying time will be less accurate. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 - ERR PL1
Good day, Recently I noticed a brief flash of ERR PL1 when changing from 17M to 15M. It happened maybe a dozen times. Not noticed before, not noticed since. I didn't record the exact frequency this was happening on. PLL 1 voltage on 15M: 21.000 5.2 21.050 5.5 21.100 5.8 21.150 6.0 21.200 6.3 21.250 6.6 21.284.399 6.9 21.284.400 2.4 21.300 2.4 21.350 2.5 21.400 2.7 21.450 2.8 Looks like there is a VFO range switch near the middle of the band. I assume this is normal. I just might have been right on the transition point, though I believe I altered the tuning to see if the RX was working OK between tests.

[Elecraft] K2 operation with internal battery
Hey gang: Just a quick question. I've been reading the K2 manuals and have some minor confusion about the operation of the K2 using a power supply. Can I operate the rig via a power supply with the internal battery switch turned on??? Just want to be sure I'm not going to hurt something. :-) Manuals say I can charge the internal battery from a power supply with the battery switch in either position. Just curious if I need to use caution while operating. Thanks and 72: Jerry N0JRN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] CW rise time mod
Or do Rev A RF boards have a lower value for C222 than that shown on the schematic? Early production K3 RF boards have a 1 uF capacitor instead of a 0.1 uF capacitor installed at C222. Yes, the published schematics show a 0.1 uF capacitor. The effect of the larger capacitor is to increase the TX waveform rise time to about 8 ms instead of 5 ms. Rev B RF boards have the correct 0.1 uF value installed. Sometime during Rev A RF board production, the value installed on the board was changed from 1 uF to 0.1 uF. Surface mount ceramic capacitors are not marked with a value, so you cannot tell which you have by visual inspection. You can determine if you have a 1 uF rather than a 0.1 uF by: 1) Measuring the capacitance if you have a capacitance meter. 2) Looking at the Tx output RF envelope on an oscilloscope or "station monitor" scope. If the fall time and the rise time look very similar in duration, you have the 0.1 uF cap. If the rise time is about 50% longer than the fall time, you have the 1 uF capacitor. You don't need an oscilloscope with an accurate time base to make this comparative measurement. If your oscilloscope has a low bandwidth (2 to 10 MHz), use the 160 meter band. 3) If you are concerned that your unit may have the 1 uF capacitor and you have no way to determine it otherwise, you can just replace it with the 0.1 uF part and sleep better at night :-) If you don't change it, you will not damage anything. Your K3 will just have slightly softer keying and an upcoming firmware adjustment of the keying time will be less accurate. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It's easy, read the revision marked on the board edge in marker pen (ouch, couldn't resist that one). Confusion seems to surround this whole issue, my K3 serial 80, which was shipped as a kit in November definitely didn't have a 100nF capacitor at C222 as the rise time dropped from 8mS to 5mS when I replaced the surface mount capacitor with one from a pack of 100nF ones.

How are you measuring power? As stated before, unless you are using an active peak power reading wattmeter, you will not be correctly reading your peak SSB output. My Diamond SX-1000 reads about 25% of the peak power on SSB. My Array Solutions Powermaster reads the same peak power on SSB and CW.

My K3, Ser. No 308, does NOT have the HAGC mod. So the SN 211 guestimate appears pretty far off. Phil - AD5X "Correct...units prior to ~211 will need it and afterwards will not. If yours is near 211 (+/-), you may need to check the capacitance of C222 using a capacitance meter. It should read ~0.1 uF (or ~100 pF) if the mod has been installed (if not it will read ~1 uF). I'm guessing on this, and hopefully Eric or Wayne should confirm, but I would expect that both the HAGC and keying mods were implemented in production at the same time, since the S/N transition is the same for both (i.e. ~211). If this is true, you can easily determine if your unit was modified by looking for a discrete 1.8k resistor installed between C196 and C197 as shown in the HAGC mod instructions. If that resistor is in place, it's a good bet that C222 has been replaced as well, but a capacitance meter will tell for sure. 73, Bill W4ZV" ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Mike: At 08:03 03/29/2008, you wrote: I have found that my VFO A knob is loose and I suspect I need to tighten the front-panel nut. It wiggles from side-to-side excessively. To do this I need to remove the rubber grip. I have seen the procedure in the operator's manual using my fingernails but this approach isn't going to work. Perhaps the grip becomes stiff with age (one month). Short of cutting it off and ordering a replacement grip what can I do? I don't know how I would cut it off by the way. I might need to get a whole new knob and rubber grip; of course I still would need to find a way to remove the knob but I at least could use some tools to remove it in that case. I tried some gentle warming with hot air directed on the knob, maybe I should get more aggressive with this approach. I removed the grip once when I first built the K3 in order to adjust friction so I do understand the procedure offered in the manual. It was difficult at that time but doable. I've had my (Field Test) K3 since JUNE '07, and the rubber ring still comes off just as readily today as it did when I received the rig. Try to use a fingernail (at the back edge of the ring, NOT at the back edge of the KNOB itself) to slide the ring forward just a small amount, then repeat this at several other points around the ring. Once you have accomplished this, removing the ring the rest of the way should be a snap. FAILING THIS, use a WOODEN toothpick to slightly wedge between the FRONT edge of the ring and the knob. Once you get a bit of the rubber 'wedged' up, deposit one (two max.) drops of isopropyl (medicine chest) alcohol in between the ring and the knob. Repeat at a couple more spots around the knob. The alcohol acts as a great lubricant and should allow the ring to slide off readily, while the alcohol will evaporate quickly leaving no residue. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 VFO A knob grip removal
Mike: My K3 (#295) is now almost exactly 2 months old. The "fingernail" method still works here (just tried it). I cannot say if Elecraft changed the grip material between yours and mine, cuz I don't know. Alternatively, I tired (just now): Using the "cap" from a ball point pen and pushing the part of the cap that "hangs onto your shirt pocket" between the knob and the grip. It worked fine. This "separates" the two and allows for "access" to the rubbery grip. Then I also tried using a small "blade type" screwdriver (as opposed to a phillips, etc) and that worked much better, but you risk marring up the knob. After using either method (or both, depending upon what you have around the shack), you can use a needle-nosed or long-nosed pliers to grab the "rubbery grip" and gently pull it forward a little. Then you can easily go back to the fingernail method. And with respect to the fingernail method, try using two hands at once. Place your thumb(s) on the flat surface of the knob, then place your hands around the knob/grib (one "left" and one "right"). Then reach back to where the rubbery grip meets (met) the back of the knob (there should now be a "gap" there, since you pulled it the grip forward a little with a pliers), and continue to slid it off of the knob. Good Luck! de Doug KR2Q (supposedly in the WPX contest right now, but gosh, the bands are bad). ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 VFO A knob grip removal
It certainly hasn't become stiff after 3 months on my K3. not sure why fingernail won't work for you? I can just put both thumbs on the front of the knob at about 10-to-2 and put 2 fingers from each hand 'over' the know and us my nails to gently pull the rubber grip forward. As I do that I can move my fingers futher over the rubber and it gets easier too. How about a plastic knife or wooden implement - a lolly-pop stick we'd say, you might say popsicle (if I understand the item correctly), perhaps a gentle prizing around the rubbish at the back? I'm guessing you didn't build the kit otherwise you would know how it went on and how easy it actually is to remove.

I tried some gentle warming with hot air directed on the knob, maybe I should get more aggressive with this approach. I removed the grip once when I first built the K3 in order to adjust friction so I do understand the procedure offered in the manual. It was difficult at that time but doable.

[Elecraft] K3 VFO A knob grip removal
I have found that my VFO A knob is loose and I suspect I need to tighten the front-panel nut. It wiggles from side-to-side excessively. To do this I need to remove the rubber grip. I have seen the procedure in the operator's manual using my fingernails but this approach isn't going to work. Perhaps the grip becomes stiff with age (one month).

If yours is near 211 (+/-), you may need to check the capacitance of C222 using a capacitance meter. It should read ~0.1 uF (or ~100 pF) if the mod has been installed (if not it will read ~1 uF). I'm guessing on this, and hopefully Eric or Wayne should confirm, but I would expect that both the HAGC and keying mods were implemented in production at the same time, since the S/N transition is the same for both (i.e. ~211). If this is true, you can easily determine if your unit was modified by looking for a discrete 1.8k resistor installed between C196 and C197 as shown in the HAGC mod instructions. If that resistor is in place, it's a good bet that C222 has been replaced as well, but a capacitance meter will tell for sure. 73, Bill W4ZV -- View this message in context: http://www.nabble.com/K3-Enhancements-and-Application-Notes-Page-tp16343769p16369716.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Are you using a true peak reading wattmeter? An average meter will only read about what your seeing.

[Elecraft] K3 60m ERR TXG
Stewart Mine works fine from 5.150 to 5.419 MHz with 95 Watts output when set to "100W" on the K3 and no sign of ERR TXG messages. The alignment is set at the factory. On another 5 MHz issue, the spurious levels are poor and below specification on frequencies below the point where a relay clicks (5.250 MHz), above that point they are OK. There are spurious signals approx 1 MHz either side of the main signal that are -46 dBc when the output is 95 Watts on 5.150 MHz. 73 Dave, G4AON K3/100 #80 == Following the recent posting of the European 60m BPF adjustments, I decided to set mine up. I am having difficulties getting a sufficient bandwidth for the UK allocation which is 5405kHz to 5260kHz i.e 145kHz. The bandwidth between ERR TXG messages is approximately 120kHz. I think that the US allocation runs between 5405kHz and 5332kHz i.e 73kHz, so that should not give any errors. Has anybody else had this problem ? 73 Stewart G3RXQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] power troubles
Todd Since the original manual was written, there's been a subtle change to the operation of the TUNE button on the K3: Originally the TUNE button gave a power level as set by the PWR control, in the more recent firmware the way it operates is different. There is a menu setting of "TUN PWR" which I have set to 09.0, this gives 9 Watts when TUNE is pressed, I can still alter the power under TUNE by turning the PWR control (it reverts to 9 Watts after releasing the TUNE button). When I release TUNE the power returns to the normal use of the PWR control. With my Acom I normally drive it with about 25 Watts for 400 Watts output. If you set the menu item to "TUN PWR" to "nor" it will work at the same level as PWR is set. Not sure if that was/is the issue or not... 73 Dave, G4AON K3/100 #80 -- here is the situation: I hold xmit to tune the ameritron al 1200 to 1400 watts.Then when I key the mike all i am getting is 300 watts out. i hold tune again and it is showing hi power. help pse! 73 de todd WB2ZAB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
