[Elecraft] KX2 question
Folks … I recently invoked the latest firmware update on my KX2 (s/n 1031). Upon beginning use of the KX2 after the firmware update two changes to the operating configuration were noticed. They are: 1) Upon pressing any of the front panel push button switches, a CW identifier takes place. How do I delete this from happening? 2) The “display” push button no longer displays the several functions it once did. What do I need to do to bring back the display functions when I push the “display” button? Thanks for any help in this matter … Bud, NY1Z … __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] KPA1500 SWR meter
I have the same problem with S/N 64. I thought it might be a cable but the problem occurs on all bands, both antenna outputs and into a dummy load. I'm only about 90% sure that it is related to temperature - I was too busy working the contest to do much more troubleshooting. And I agree with the fan noise comments - the pitch of the noise comes right through my Bose noise canceling headphones. 73, Bud N7CW On Sun, May 6, 2018 at 3:43 PM Don Butler <n...@comcast.net> wrote: > Mike I had the very same thing happen last night while operating the 7QP > contest. which is the first contest I have operated with the KPA1500 > the heatsink temperature was down in the mid 40s C at the time > and > in my case it occurred on 160 meters only SWR as per other meters as > well as the digital readout on the 1500 were reading 1.2:1 ... and did not > change even when the LED flashing occurred . but I was getting > intermittent flashing of all LEDs on the amp's SWR meter > > During the contest I was continuously running on CW with hourly QSO rates > running between the 70s and 110s I opted to manually switch on the fan > to keep the temperature below 60 degs C . level 2 seemed to keep it > there most of the time but I did move up to level 3 a few times (and > BTW, at that speed the KPA1500 is clearly the noisiest amp I have ever > owned > but, arguably, it may very well be the "coolest" also . headphones > were absolutely necessary with that noisy fan . clearly much noisier > than the Alpha 9500 sitting right next door ... which I also used during > the > same contest... > > So Mike, you're not the only one experiencing this phenomenon whatever > it is.. > > Don, N5LZ (KPA1500 #45) > > -Original Message- > From: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike Crownover > Sent: Sunday, April 29, 2018 8:13 AM > To: elecraft@mailman.qth.net > Subject: [Elecraft] KPA1500 SWR meter > > I have noticed that after my KPA1500 gets above 50C the SWR indicator light > starts to show intermittent high SWR.

[Elecraft] K3 Jumps To High Output In Data Mode During Power Knob Rotation
The K3 mode button is set to DATA and the transmit mode is DATA A. As I adjust the power output (PWR) knob during continuous transmit, the measured output displayed on the Power Master jumps to a high level. As an experiment, If the output is at a steady 40 W for example, when I slowly and continuously rotate the PWR knob, the output jumps to 150+ watts output during rotation of the PWR knob. As soon as I stop rotating the PWR knob the output is steady at the chosen output. If I choose a different power output during receive, the output is momentarily very high and then drops to the selected output – Overshoot. No Overshoot if I don’t change the PWR knob. This is causing havoc with the amp. Out of curiosity I tried this in CW mode. In CW when I turn the PWR knob during a continuous transmit, the output does not jump to a high level but rather it follows the PWR knob setting smoothly. What may be the issue? 73, Bud W3LL w...@arrl.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] headphone impedance
Perhaps this will help: Look up the specs on a good home audio amplifier — say, QSC or Crown. You’ll find something called “damping factor”, and it’s often 50 or more. Roughly speaking, it’s the ratio of the (loudspeaker) load impedance to the internal (source) impedance of the audio amplifier. So modern semi-pro and stereophile audio amplifiers are “grossly out of specs”, as you put it. I have a legacy, hernia-inducing McIntosh power amplifier, circa-1960s, with output transformers and three taps — for 4-, 8-, and 16-ohm loudspeaker loads. Nothing I’ve owned since then uses output transformers or matched loads. Most audio amplifier designs these days are voltage followers. Most manufacturers don’t attempt to match source impedance to load impedance. Highly damped output stages are “good” things to have. Yes, it’s true that voltage-follower amplifiers deliver more power to low-impedance loads than to high-impedance loads. But if I were to follow your line of reasoning to its logical conclusion in the home audio arena, I would conclude that 4-ohm speaker systems are sonically superior to 16-ohm speaker systems simply because they require more output power from the audio amplifier to play my music collection. Does that seem like a reasonable way to choose your stereo system loudspeakers? Or headphones for your K3? If your 100-ohm (or higher) headphones can’t provide reasonable levels of undistorted sound pressure at your ears when your K3 or K3S audio gain control is at, say, 9 or 10 o’clock, perhaps it’s time to buy a new pair of “cans”. That’s certainly gotta be cheaper than reverting to a 75A-4 with its audio output transformer and 500-ohm tap.

One was that narrowing the BW also improves the S/N. Maybe. Maybe not. Or, maybe up to a point. I believe that whether one observes monotonic improvement in ability to decipher the intelligence carried in a very weak signal as one reduces receiver BW will be a function of _how_ the BW is narrowed in the various electronic circuits and/or digital algorithms, as well as a function of our own individual hearing characteristics. Perhaps I am not on the main part of the normalcy distribution curve (my close friends will assure me I’m _not_!) but I know for a fact that many, many times I have been best able to pull intelligible information out of a very weak CW signal on the low bands by using a receiver BW somewhat _wider_ than that provided by my narrowest filtering options. I have used primarily Kenwoods and (more recently) the K3 for most of my serious low-band DXing efforts, but I can’t tell you if this effect is more or less apparent in one model vs. any other. I am also a strong believer in what I have been told is “stochastic resonance” as an aid to hearing and copying the intelligence carried in weak signals. I have found repeatedly, for instance, that I am more apt to hear certain “unusual” vehicle sounds from the engine compartment or underbody when I have the car radio playing music within a certain range of amplitudes.

Re: [Elecraft] Internal SWR Readings
Rick, I believe you're confusing SWR and impedance. If a transmission line is lossless, the SWR will be the same along the entire length of the line. If a transmission line is lossy, the SWR will get progressively lower as you move closer to the transmitter. In an extreme case (such as 1000 feet of old RG-58 or worse, at high enough frequencies), there will be so much loss in the line that EVERY antenna will look like 50 ohms back at the transmitter and the SWR will be 1:1 there! So the transmitter end of the line is the LEAST useful end to look at SWR. However, the COMPONENTS of the transformed antenna (or load) impedance DO vary along the line. And It is the antenna IMPEDANCE that repeats every 1/2-wavelength back toward the transmitter from the antenna end -- not the SWR. At all other points along the transmission line, unless the antenna impedance is purely resistive and exactly the same as the characteristic impedance of the transmission line the load impedance seen along the line will be a combination of resistive (real) and reactive (imaginary) parts. Those two components of impedance continually change in amplitude with distance (in wavelengths) along the line, repeating every half wavelength along the line. So if you have an impedance meter (rather than an SWR meter), you will, in fact, see those values of R and X vary from point to point along the line. But many, many, many combinations of R and X can all result in the same SWR. A very good way to see how R and X vary with distance back from the antenna along the transmission line -- even though the SWR remains constant -- is to understand what a Smith chart displays. One reason practical SWR meters don't read the same value of SWR on a line -- even at the same point on the line -- is because different circuit designs may have different amounts of error, or inaccuracy, for different amplitudes and combinations of R and X. And the greater the mismatch between the antenna (or load) impedance and the characteristic impedance of the transmission line, the larger those swings in R and X along the line will be. Thus, I'm not surprised that the SWR monitor in my K3 often shows a different SWR than my Kenwood wattmeter at essentially the identical point on the transmission line to my antenna. Even the world-renowned Bird wattmeter doesn't always do so well! There are many good treatments of SWR, transformed antenna impedance along a transmission line, and the use of Smith charts on the web and in many antenna books.

Of course, if you use a single-lever paddle, or if you never employ paddle-sent code, this won't matter to you, but I prefer dual-lever paddles, and I make far fewer mistakes with Ultimatic mode than either of the common iambic ones. Combine that with the near seamless relationship between the WinKeyer Host Mode and good general purpose or contest logging software on a PC or Mac, and I can't imagine doing without it. I love my K3, and I'd love to eliminate one more accessory box, but not at the expense of the WinKeyer's features.

'Sync and link' already happen automatically when entering Diversity mode. If the manual Link control is removed, Diversity would then become the easily accessible 'hold' feature of the SUB button (available if the second receiver is present, otherwise having no effect). I would love having Diversity become the easily accessible HOLD feature of the SUB button, as suggested by Ian. But if the manual Link control is removed, how would one then engage it for non-Diversity applications? Another source of confusion in Diversity mode is the frequency display for VFO B, which is not the true frequency of that VFO. (Obscurely, it is the frequency that VFO B *would* jump to on TX, *if* the operator *also* chooses to engage SPLIT.) That false frequency indication can easily mislead the operator into believing that the two VFOs have not been successfully synchronized. In normal diversity reception, the display should show the *true* VFO B frequency - reassuringly synchronized and slaved to VFO A. It should only display that alternative frequency if SPLIT has actually been selected. I understand Ian's point about confusion in Diversity mode; I suffered from that the first few hundred times I used it, too. However...I think I'd still like to see where VFO B would jump to on TX before engaging the SPLIT button. For me, a better solution would be to dim the VFO B display (relative to VFO A intensity) when in Diversity mode and Split has not been selected. (I have no idea if that would be possible.) The slowly blinking decimal point is a bit too subtle and requires me to stare at it far too long to be the right way to indicate Diversity mode for me.

Re: [Elecraft] What does the frequency readout mean?
On Feb 20, 2013, at 8:02 AM, Pete Smith N4ZR n...@contesting.com wrote: For some reason, I was operating under the mistaken impression that the sideband used for CW followed the sideband convention for SSB. It's been many decades since the sideband used for CW switched with the USB /LSB convention (above and below roughly 9 MHz) with most mainstream rigs. The sideband used for CW is constant across all bands in the K3 and also in Kenwood rigs. Unfortunately, those conventions differ. I prefer to listen to CW using what would be called USB mode on sideband. On the Kenwood TS-940 and TS-950SDX, that corresponds to their CW mode. On the K-3, however, that's CW REV -- a difference that drives me bananas when I have the K-3 as Radio 1 and my Kenwood as Radio 2, because my general purpose logging program requires both Radio 1 and Radio 2 to be the same! That said, however, suppose your K-3 is in CW REV mode, which tunes the same way as USB would. That is, as you tune from the bottom of the band up higher in frequency, and assuming you have your filter passbands centered normally, you will hear stations come into the filter passband with DESCENDING pitch. They will exit your received passband with a LOWER pitch than when they entered as you tune UP in frequency. So now let's look at the question you asked in your other posting: Same setup, but listening to a signal on the air. Beat note is ~500 Hz. I turn the main tuning knob so that the received signal is lower frequency - say 200 Hz. I transmit. What does the station on the other end hear, assuming he is also using USB-CW? Does my beat note go up in his receiver, or down? When you turn the main tuning knob so that the received signal is lower frequency, you are tuning UP in frequency if you are in USB or (in the case of the K-3) CW REV mode. What the station on the other end hears, however, depends on his rig and which mode HE is using to listen to you with. If he, too, is using USB mode (or a K-3 in the CW REV mode), he will hear you get HIGHER in pitch. If not, he'll hear you get LOWER in pitch. It's been my general (statistical) impression, listening to DXpedition operators over the years, that if the operator appears to be tuning UP the band in small increments he's most likely to be listening in USB (or K-3 CW REV) mode, since many of us cut our teeth on that technique when we were neophytes. I, for one, much prefer to listen to another station's pitch sliding DOWN in frequency as I tune higher in the band. Thus, I use CW REV in the K-3, and I tune from the bottom up. So, short answer to your question: It depends.

Re: [Elecraft] K3 power drop and ERR 12V
Mark -- Having gone through the ERR 12V experience a year ago, I can suggest: 1. It might the a high resistance in the circuit breaker on the rear panel. 2. It might be high resistance in the card edge connector pins that transport high-current 12VDC for the 100-w KPA3 module into and out of the KPAIO3 which is vertically positioned at the rear of the K3. 3. There are some other esoteric possibilities that are extremely low probability, so I won't go into them. My circuit breaker was fine, but the contacts on the KPAIO3 board were not doing the job. Elecraft sent me replacement pins for the connectors but in the interest of time I simply soldered two short jumpers (#12 or #14 insulated stranded wire) across the offending pin-pairs. It takes longer to describe it than to do it. It's an hour, start to finish, including taking one side panel off the K3 to get at the appropriate pins on the KPAIO3 and mating boards.

Re: [Elecraft] {K3 KX3} Software CW in K3 and KX3 and contesting
Yay! I second that motion, Don! I've been a fan of Ultimatic mode since it first came out in QST as a vacuum tube keyer from a W6 in the mid-50s. Later I built the transistorized version that was in QST in the early 60s. But nothing's as easy as building a WinKeyer kit with it in it! Steve did all the heavy lifting. Ultimatic mode also includes dot or dash insertion. Make a Q, for instance, by holding the dash lever closed through the entire character formation and flick the dot lever after the start of the second dash to insert the single dot. It's nice to have the K3's built-in keyer when going portable. But -- like Don -- I have a lot of trouble using the Iambic algorithms with dual-lever paddles, so at the home station I use a WK2 and when I'm traveling I use a single-lever paddle.

Re: [Elecraft] Software CW in K3 and KX3 and contesting
Hi, Will -- Q was probably not the best choice I could have used to distinguish between the two modes. My biggest problem with Iambic and a dual-lever paddle is the number 2, which I do have to send occasionally:-) It typically comes out as dit-dit-dah-dit-dah. For me, at least, I think the crux of the difference between the two algorithms is that I can be sloppier about when I get my thumb or fingers off the first lever squeezed on a large number of characters, such as the A, W, J, 1 and N, D, B, 6 families. This timing becomes increasingly critical as sending speed increases. For instance, I can send a 2 quite consistently using dual-lever Iambic at slow speeds. I freely admit that my difficulties with Iambic may be influenced by the characteristics of keyers I first used, prior to introduction of the Iambic algorithm. In other words, if your first electronic keyer was Iambic, you may not have as much trouble as I with it. An aside: One of those early keyers I loved, the POO-keyer from K2POO, was a (vacuum tube!) dash priority or dash override design -- not so much by deliberate design, perhaps, as by the reaction of the analog circuit to having dot and dash contacts simultaneously closed. Ultimately (get that?), I think the answer is this: If you're perfectly happy with the Iambic algorithm in conjunction with a dual-lever paddle, and it's making good characters for you, or if you use only a single-lever paddle, stick with the Iambic. If it's giving you fits, however, an Ultimatic keyer might be just the ticket for you.

Re: [Elecraft] Noise from compressor
Hi, Robby — The noise is very likely coming from the pulse-width modulation (PWM) circuitry that runs the blower motor located in the air handler enclosure (often located in the attic or on the top floor of a residence). In poorly designed and shielded circuits the noise can escape from that enclosure out into other parts of the A/C system — riding on wiring to the thermostat(s) on the walls and on power leads to the outdoor unit. In one installation I saw, the air handler enclosure in the attic provided a very good shield, preventing direct radiation from the circuit. However, the high frequency energy from the PWM was leaving the enclosure and radiating to nearby antennas via the thermostat wiring (and to a lesser degree, the power wiring to the compressor). At least one manufacturer sells a kit (priced in the $100-$200 range, plus local labor) that is meant to be installed at the air handler by one of their authorized dealer's techs. Whether it's effective or not, I can't say, and you might be able to convince them that as a long-time radio amateur you can do the installation yourself. Be very careful about assumptions as to the source of the noise; so much of the wiring between the various components of the A/C system is unshielded that it's hard to say for sure until you do some detailed sniffing with an AM radio or other suitable detector. I doubt, for instance, that an HF beam can distinguish between the direction to the compressor and the direction to portions of your interior wiring. In the system I mentioned above, in that residence the peak noise pickup was around the thermostat on a hallway wall on the first floor of a two-story (plus attic) building. You'll probably do better with this kind of question on the RFI reflector. I suspect the K3 is incidental to the issue. Bud, W2RU On Apr 30, 2012, at 8:20 AM, Robby.VY2SS wrote: Riddle me this!

I removed the 220VAC from the compressor at the breaker panel. The noise is gone. 2. I turned the breaker back on and put my indoor units on fan only. The noise is gone. I guess this proves the noise is coming from the compressor. Also when I turn my beam toward the compressor the noise increases. 3. I disconnected my power supply and connected the K3 to a battery.

Re: [Elecraft] K3 TX delay
when a DX station has come back to someone while I'm still sending. Finally, with respect to amplifier QSK: I am aware of five ways of enjoying QSK capability when using a separate amplifier: 1. PIN diode circuits (Alpha 87A, some Ameritron models, some outboard PIN-diode boxes) triggered by the KEY OUT line from the K3 2. High-speed reed and vacuum relay combinations (current Alpha models, AG6K circuitry, etc.) triggered by the KEY OUT line from the K3 3. Electronic bias switching (EBS) in conjunction with a shunt-type vacuum tube TR Switch (E. F. Johnson, e.g.) and requiring NO trigger signal 4. EBS in conjunction with a separate RX antenna (always with suitable RX front-end protection, of course) and requiring NO trigger signal 5. Diplexing schemes which don't care if / when the transmitter is keyed Most important, the clunky, noisy, typically open-frame relays used for manual, PTT T/R switching in many amplifiers should NEVER be considered capable of being used in QSK mode! In fact, many of these relays are sufficiently slow that they shouldn't even be used in VOX mode because they'll be hot-switching RF, even with the delays in the K3. PIN diodes and EBS can be VERY fast — with total switching times under 1 or 2 ms. Inexpensive reed and vacuum relay circuits typically perform in 2 or 3 ms, thanks to the use of speed-up circuit techniques. With respect to #3 above, the maximum voltage out of the RX ANT terminal of a Johnson TR Switch during transmitter key-down periods is high enough to trigger the internal RX front-end protection circuitry in the K3, so it is not a viable approach, even though I have successfully used Johnson TR Switches with Kenwood solid-state transceivers for over a quarter century. And FAR more than a quarter century ago I began my own ham career with a form of #4. I used a separate receiving antenna and the EBS was very simple: all my CW rigs and amplifiers back then were operated in Class C mode, and fully cut off during key-up intervals!

[Elecraft] K3 RX antenna input protection circuits
I have a question about the receiver front end protection circuits in the K3 — specifically, the ones on the RX ANT IN and AUX RF inputs. When I went to the schematics, here's what I found: AUX RX feeds the KRX3 Sub Receiver board, where it goes to a gas discharge tube (SA1) shunted by 470K. THe voltage there (schematic name RF SENSE) then goes through a 2 pF coupling capacitor to a Schottky Barrier Diode assembly driving a Darlington relay driver. The base of the Darlington is shunted by a 470K resistor in parallel with a 10 uF capacitor. RX ANT IN is on the KXV3 Connector schematic. It goes to a SPARK GAP (GAP1), shunted by 100K. That voltage then goes to C1, a 2 pF capacitor driving an identical Schottky Barrier Diode pair and another Darlington circuit. The base of *this* Darlington is shunted by a 1 Megohm resistor in parallel with a 0.1 uF capacitor. So Is GAP1 the same as SA1? If so, and ignoring the difference between 470K and 1M, why is there a factor of 100 difference in the capacitors in the Darlington drive circuit? It seems to me it's going to take 100 times as much charge to forward bias the base of the AUX RX Darlington as it is the base of the RX ANT IN Darlington. Is there a reason for such a huge difference? I ask because the RX output of my electronic (vacuum tube) TR switch keys the RX ANT IN COR but not the AUX RF COR.

YOU may have an FT-1000D sitting there, but I don't. What I said pertained to ME and the rigs I named, and was QUITE true. But your example helps me make the point I was originally trying to make. Read on. 75A4 switch works counterclockwise also, left to narrow. The 75A-4 worked whichever way you chose to install the mechanical filters, so it was akin to the suggestion that the direction of WIDTH control knob rotation on the K3 be user-selectable. One could just as easily put the narrowest filter in the MIDDLE position in the 75A-4. And it is the exception that proves the rule in a long line of fine receivers. Both earlier and later Collins receivers (such as the 75A-2 and the 75S-3) very definitely narrowed the bandwidth with clockwise rotation. Even in the 75S-3B/C (which also had user-fillable mechanical filter slots) the narrower CW filter positions were clockwise from the wider SSB and AM positions. But your FT-1000D brings me back to my original point: Each of us individually arrives at the K3 with a unique set of life experiences. You're comfortable with the rotation vs. action of the K3 WIDTH knob, and I'm not. From a purely logical point of view, the operation of the WIDTH control on the K3 is consistent with other K3 controls such as AF GAIN and keyer SPEED. I doubt any of us would be happy with a backwards speed control. (I can say that because I once owned one, and everyone who tried it hated it!) Self-consistent operation of the controls is a nice objective, and quite appropriate to test equipment, but it can bite us in a fast-paced, real-time operating event such as a contest when it's contrary to habits we have formed or is the opposite of what goes on in the second rig of an SO2R setup. My own view is that -- regardless of the habits you or I may have formed or the rigs we may have been used to in the past -- the K3's WIDTH knob is fundamentally counterintuitive because historically I've never heard anyone say they were dialing in bandwidth -- the hams I've been around have always dialed in more selectivity on an as needed basis. In fact, our lingo is replete with references to cranking in selectivity or narrower filters. The analogy to mechanical cranks is clear and long-standing, and I know of no mechanical cranks that perform their primary function by having their handles turned counter-clockwise. That's the REAL source of my difficulty with the K3 W IDTH control. In effect, it's a cultural pre-conditioning that goes beyond the rigs I have or have not had the opportunity to use. So, from my point of view, the WIDTH knob would be better named the SELECTIVITY knob or the FILTERING knob or the NARROWING knob, and it would have the opposite action with clockwise rotation as it does today. But all those names are far too long for a front panel as small as the K3's. Besides, during a contest, when it matters, I don't look at the names over the knobs or at the little displays that show the bandwidth increasing or decreasing, either. I just try to make contacts as fast as possible. For that, I agree with the person who said it would be really nice if the function of the WIDTH knob was user-selectable.

Why have I not replaced the laptop by now. I was going to buy a new superduper modern laptop but did not do so for the following reasons: senior senior year, lazy, disorganized, dithering over which computer and how much to pay. Recently someone gave me another old IBM laptop with Win2000Pro so I thought I would set it up temporarily in order to use N1MMLogger for casual contesting and logging. It is now all set up except for the Prolific driver. I don't remember how I got the driver for the original set up. If it was a CD. I can't find it. I have downloaded 7-Zip.

Re: [Elecraft] Learning Code, Etc.
Reading the various emails on this subject, I can't help but put in some of my memories. At age 17 in 1940 I got my ticket with the call W8VHF in Detroit, MI. Have never used VHF. Learned the code by using a 2-tube regen rcvr to listen to cw on 40 and 80m and by listening to some naval stations until I could copy the stuff. Had a buzzer to learn sending. Since then I have been using cw about 98% of my operating time. I'm not a high speed operator. I remember two guys who were whizzes on cw. One was W8CW: I think his name was McDonald, he was a telegrapher for Bell Telephone in Detroit, and a runner up to McElroy in cw speed contests. The second was Win Peebles, W8GQB, one of my Elmers after I got my ticket. Earlier in his life he worked for one of the broadcast stations or newspapers copying national and international news sent out by the news services. Perhaps it was Press Wireless. He claimed he could do the following. Copy the code on a mill, stop and eat a candy bar, get a drink from the fountain, and go back to typing where he left off. I believe it. By the way one of the emails on this list, or maybe the DxLab list, mentioned being trained for maintenance of high power transmitters for the navy. When WWII came around the Signal Corps sent me to Press Wireless for the same kind of training. However, on arriving in the Pacific war, I never got near a big transmitter.

Re: [Elecraft] ERR IO3 more!!
1. Unless you have a shielded power line coming to your house, it's unlikely the lightning surge you describe would appear on the telephone line yet go undetected by the power lines. 2. The most probably cause of the damage you describe is that the power line ground / entry point, and the telephone line ground / entry point to your dwelling were not the same. I believe your modems (and the other PC hardware they were connected to) were destroyed by the _difference_ in the lightning-induced common mode voltages on the power lines and telephone lines at the point where they connected to your PCs. I, too, have suffered this kind of damage -- damage limited to those devices that are bridged across power and telephone lines. The solution is to bring both (or all) utilities into the house at the same entry point (and your antennas and control lines, too, of course), and to make sure the grounds of everything are tied together at that point. You want all your electronics equipment tied together in low-impedance fashion (at lightning frequencies -- i.e., in the 1+ MHz range) so that everything rises and falls together with the surge on the utility lines. Adding other protection (UPSs, surge suppressors, etc.) may be helpful but most of that stuff will be overwhelmed when the two utilities feeding your PC and modems are not surging in unison.

Mine come to me under the lake I'm on. But my phone lines used to come in at one end of my house, and the power lines at the other. They now come in right next to each other -- both still buried all the way. It cost me an excavation contractor to dig a trench for the phone company to move the telephone line to come in where my power cable entrance is, but after experiencing two separate $3000+ losses in earlier years, I figure the cost was well worth it. Now all utilities (AC power, landline telco, and satellite TV cables) enter the house within two feet of each other, and their grounds are tied together directly below the AC power meter. The grounds for all my feedlines and outdoor antenna control cables are at this point, also. The most expensive things in my shack (or maybe my entire house, now that I think about it) to replace are my K3 and my amplifier. The K3 and associated computer are fed off the same UPS, as are all accessories that have any connection to the K3 or amp (rotator control boxes, 12V DC supply for antenna switches, etc.). I use WiFi to connect all my PCs (but especially my radio computer) to the outside world (including my home printers). For my desktop PCs that don't have WiFi built in, I use inexpensive little NetGear USB WiFi adapters. I want no surprises from sneak wiring paths coming to my radio equipment. Most of my ethernet cabling that I installed ten years ago is currently unused. The amplifier isn't buffered from surges by a UPS. The best I can do there is my whole-house surge suppressor across my AC mains plus having all my grounds in the shack tied together plus having all my exterior wires and utilities grounded at the same entry point to the building. (Well, I could unplug the amp, I suppose.) Today only three things in my home bridge the power and phone lines: my fax machine (which I manually plug into the telephone line only when I'm sending or expecting a fax), the base station for my cordless telephone system, and my satellite TV receiver. The cordless base is inexpensive to replace, I wish my fax machine would blow up so I would have an excuse to get a decent one, and except for HGTV and Wipeout I wouldn't miss the satellite TV at all. We've had at least four major lightning storms come through this area in the past two weeks (probably more than we had all last summer!) and there were definitely some nearby hits (one second or less from flash to sound).

This allows us to quickly spin the Main Tuning knob to any of our side frequencies at any time during the net to check on the progress of pairings. Since we often having pairings up or down 10 or 15 kHz from the net frequency, any automatic Split turn-off feature that's suitable for DXers and contesters as proposed above would negate the value of the second RX for net controlling.

Re: [Elecraft] OT - Vertical Bug
Some of you are old enough to remember that back in the mid 50s my nemesis in the old ARRL CD Parties was my fellow Western New Yorker, Keith, W2FEB. But Keith also gave me what is probably a collector's item for my old garden-variety Vibroplex bug -- a special weight. I, too, had a Vibroplex that didn't like to go down low enough in speed to suit me. I, too, tried using _two_ of the standard Vibroplex weights, with unexciting results. I, too, tried wrapping turns of solder around the standard weight. Keith worked at a machine shop in Lockport, north of Buffalo. He designed and fabricated a special weight that was narrower than the the stock Vibroplex weight, but had a much larger diameter (and perhaps higher density, as well). His primary purpose in designing it was not the lower speed but, rather, the desire to be able to change speed without messing around with the knurled set screw on the normal weight. So he built into it a spring-loaded ball bearing that kept it in position on the shaft, yet allowed it to be slid farther in or out on the shaft with two fingers and a thumb (generally on the same hand). Really cool. (Kewl?) This is not totally off-topic, since I occasionally hook up my old Vibroplex with W2FEB's weight and try sending with a bug using the sidetone on my K3 with the VOX disabled.

Jorge, Yes, we use several of the same supplies for the full 48 hours with no problems and no RFI. You must remove an internal jumper wire for 220V operation. You can see the eham reviews at http://www.eham.net/reviews/detail/ . I did look at the PowerWerx supply - it is smaller and rated at 25A and the USA price is within $10. It is apparently brand new - it doesn't have a eham review page and it is not in stock.

In the monitor I hear what sounds like PSK being sent and the wattmeter shows full quivering power out. However, no one responds to me. I did a test with one station switching back and forth between Data-A and PSK-D to prove the point. I don't know were the signal is going in PSK-D.

[Elecraft] No Receiver Mute with PTT
Hi K3 Group, After many months finally found time to set up my K3 with MH2 microphone. Got it updated to version 3.11 and operating fine on cw. But SSB is no go. Using earphones it seems OK and had a QSO that way. Upon removing earphones to use the speaker, WOW, blasted out of room with audio squalling when press PTT. Same thing happens with earphones connected and hold mic next to earphones when use PTT; not loud though. Same thing with zero power or in TEST mode. Have tried various changes in configuration but no luck. Don't think the following is connected to this problem but have noticed that when turn rf gain down to zero the S meter moves all the way up to 80 over S 9 and have been told that on the air my voice sounds like too much base. If anyone knows the solution to the audio feedback, I would appreciate it if they inform me on what to do. Perhaps a another FW download is needed or perhaps a go at parameter initialization. Sure hope it is not a hardware. Thanks for any help. 73, Bud Morin, K9ZT __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 ERR KEY - Continuous Keying
My K3 display shows ERR KEY when I turn it on. It's been working flawlessly until now and no recent changes have been made. 1.No programs are running on the computer. ERR Key is displayed on the K3 2.If I shut down the computer the ERR Key turns off partway thru the Windows is Shutting Down screen. 3.If I turn on the computer with the K3 on, it keys the transmitter a few times then it keys on continuously after windows comes up. 4.I disconnected both the RS232 and ACCY cables from the K3 but surprisingly the K3 remained keyed with the same symptoms. 5.I disconnected the Line Out cable from the K3 and it unkeyed. However, it would periodically/intermittently key for about half a second on its own. 6.I reconnected the Line Out and the K3 again keyed continuously. 7.I disconnected the Line In cable from the K3 and the K3 unkeyed. However, it would periodically key for about half a second on its own. 8.I checked both Line In and line Out cables for continuity or shorts. Both are OK. 9.I checked the sound card for functionality using a second radio. It works properly for both Line In and Line Out. 10. Both Line In and Line Out cables are stereo cables. 11. If the K3 is on when windows starts up it goes into key down mode. If I start windows with the K3 off and then turn the K3 on the K3 displays the ERR Key diagnostic. I don't understand what Line Out or Line In has to do with keying the transmitter. Any suggestions on what happened and how to fix it? Until now all has been perfect. 73, Bud W3LL w...@arrl.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 FSK Passband Frequency
I'm using FSK-D. To tune in an FSK signal I need to use Shift to shift the signal to the right of the passband display on the K3 (centered over the right side arrow). This then places the signal in the center of the MTTY display. However, received signals are now about 0.55 KHz higher than spotted reports. If I click on a spot I have to search for the signal. Normalizing the K3 passband puts the signals completely out of the receive passband and nothing is heard or seen in the MTTY display. Is this normal or am I doing something wrong?

While your comment makes some sense, this is the first time I have heard anyone complain about teh original operation of the CLR control. 73, Don W3FPR Bud Semon N7CW wrote: When I have the RIT on and I press CLR, the RIT is cleared. So far so good. When I press CLR again, the original offset reappears. I would expect that pressing CLR a second time would just verify the frequency delta is 0. If I want to switch between an offset and none, I can turn the RIT on and off. Is there a feature here that I'm missing? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] [K3] AGC
I have the CONFIG: AGC SLP parameter set to 15 also and I think it is not aggressive enough - that is, the volume difference is too large between weak and strong signals. 73, Bud N7CW -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Cunnings Sent: Monday, July 07, 2008 7:18 AM To: S Sacco Cc: Elecraft Reflector Subject: Re: [Elecraft] [K3] AGC Have you tried adjusting the CONFIG:AGC SLP parameter? I've set mine to the maximum value, 15, for flattest AGC slope.

There are large differences in audio volume when receiving different strength signals. I have not been directly comparing the K3 to another receiver, but it keep surprising me (in a bad way). On a couple of occasions, I had to rip off my headphones, because it was faster than reaching for the volume control. I seem to remember this being somewhat of an issue with earlier firmware versions, but I'm running 2.13 at this time. Is anyone else having this issue? 73, Steve NN4X ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Split ops?
Hi Tom, You need to tap A=B twice to transfer all the parameters, freq, mode, etc. 73, Bud N7CW -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of TMorton Sent: Friday, July 04, 2008 8:56 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Split ops? When making the selection AB then holding Split I notice that the mode stays where it last was...i.e., 14005 on A and 14180 on B; after AB the B vfo is 14005 but remains in USB. I have looked thru the menu selections and can not find anything to have the modes match after doing AB...have I missed something? If not, why not match freq and mode? 73 Tom CX7TT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
