Re: [Elecraft] Weller temp setting for KX1 build
Thanks Don and Brett, Just the bit of info I needed. Thanks again for the help, I'm really excited about building my KX1. I spend some extra money to make sure nothing goes wrong with ESD(I got a mat, wrist strip, and Monster surge protector with coax hookups, I figured I could use it to ground me and the mat and have ground fault protection for the soldering station). I also got a nice panavise to help with soldering/desoldering. I hope to start in on the build tomorrow, only thing I lack is a dummy load, but I might be able to borrow that from a friend.

RE: [Elecraft] Weller temp setting for KX1 build
I built all my elecraft stuff with the soldering iron set at about 630-660F. Bigger parts needed more heat, but for almost everything small, and the .020 solder, that heat was enough to give a nice solder connection. I had zero solder problems on all my stuff.

Re: [Elecraft] Weller temp setting for KX1 build
Chris, I find a setting of 700 degrees F about right for me. An even better indication is to see how long it takes for solder to flow. If you can achieve a good solder connection in 2 to 3 seconds, that is about the right temperature. If it takes longer for the solder to flow out to a nicely tapered edge where the solder edge is almost invisible on both the solder pad and the component lead, then your temperature is too low - if the solder flows in 1 second or less, then the iron is too hot. Take a look at the soldering tutorial on the Elecraft website Builder's Resource page to see what a good solder connection looks like. 73, Don W3FPR Koaps wrote: Hi Guys, I'm getting ready to start in on my KX1 build but one thing I'm a bit stuck on is the setting for my new Weller WES51 solder station.

Also rechecked diodes D1 - D8 and all check OK (unless I installed ALL of them backwards). Should I have to remove the heatsink - as you did, I guess, it looks like just removing the 3 screws holding the back plate on, the 7 standoffs and the 4 screws that hold Q1, Q2, Q3 and Q4 should do it. I guess I won't have to remove the back plate - I REALLY didn't want to do that.

[Elecraft] Re: [ Elecraft] Switching Power Supply Reccomendations Wanted
Craig, The old SMPS/linear supply finer points have been around a while, and while I use a switcher here on one set with what I perceive to be no switching noise at all, it is a different story if I re-locate to a beach house we have where the ambient noise is virtually zero. There, the SMPS difinitely has a low level of noise mainly on the lower bandsthat manifests itself as a low level "mobile" rasping that drifts around slowly every few khz . At home I would swear it was clean.( and I have a quiet location for all intents and purposes) However, the small amount of switching noise doesn't worry me for the short times I am portable, and the convenience of not putting an arm out of joint carrying around a transformer derived supply far outweighs any noise I encounter. Having said that, if you want completely noise free operation, then the linear supply will win hands down. I have used home made switchers that I have put a lot of effort into trying to get "absolutely" clean and never 100% achieved that goal. I eventually fell back on MFJ switchers, which I find as good as any, and there is a $99 model that is small, light and very portable, and probably as "clean" as you will get in a switching supply. There will be others on the market much the same ( Samlex?) To round upyou can't beat the switchers for portability and convenience, but buy a "Brand name" model. In most suburban or density locations you probably won't notice any noise. However if you are going portable where man made noise doesn't exist, the Linear supply, or batteries will win out every time. It's the old story of YMMV.

[Elecraft] K3 front-end protection
Hi Toby, [NOTE: I'm so busy that I'm answering about one e-mail a day, now, and yours is it :) Normally someone else will answer, or the answers will end up in the FAQ later on.] 1) A friend of mine with a big 160m station killed his RX front end because too much power was coming back on his beverages and the rig's RX antenna input was not grounded / disconnected during transmission by the transceiver. Are the K3 antenna inputs which might be used for RX only antennas protected against too much power coming back via the RX antenna? All antenna ports have gas-discharge tubes, and the RX-only ports also have carrier-operated relays. We also monitor the SWR bridge in receive mode (forward/reflected power). If a signal large enough to cause front-end damage appears in the main T-R path (a "reverse transmit" condition), we quickly open the PIN diode path to the receiver, typically in less than 1 ms. The path will recover equally fast when the huge external signal disappears. Obviously this situation is to be avoided, which is why such stations often use external band-pass filters. 2) At our contest QTH when we work multi between some of the antennas we also have a lot of power coming back - roughly 20W in the worst case combination of beams and bands (without the extra band passes). How strong is the RX front end of the K3? How much power can it handle without releasing its smoke? See above. At a certain power level the RX path will be opened (and the audio muted) to avoid exposing the preamp, mixer, and down-stream stages to multi-watt signals. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Julian. THere is no waterfall display on the K3. Part of the S-meter is used for tuning CW, PSK and RTTY.

Since the K3 is reported to have a built-in capability to receive datamodes, which presumably includes some kind of waterfall display, could this not be developed in some future firmware release to give a bandscope type of display in other modes? I would be quite happy to toggle between the sub-VFO display and a bandscope. Since the datamodes capability is an aspect of the K3 I'm really keen on, it would be nice to see a picture of the display with the radio receiving some PSK31, just to see what it looks like. In fact, as one of the many who was unable to go to Dayton, and whose first sight of a working K3 is likely to be when the one I ordered has been completed, it would be great to see a video like the one on YouTube, but of a K3 actually on the air, with someone going through the controls and demonstrating things like how the DSP works and the effect of the different roofing filters.

[Elecraft] A couple of K3 Questions which kinda got lost
Hi Wayne, a while before Dayton I asked and, with the amount stress you guys were in, understandably, didn't get an answer either that or I missed your answer. 1) A friend of mine with a big 160m station killed his RX front end because too much power was coming back on his beverages and the rig's RX antenna input was not grounded / disconnected during transmission by the transceiver. Are the K3 antenna inputs which might be used for RX only antennas protected against too much power coming back via the RX antenna? 2) At our contest QTH when we work multi between some of the antennas we also have a lot of power coming back - roughly 20W in the worst case combination of beams and bands (without the extra band passes). How strong is the RX front end of the K3? How much power can it handle without releasing its smoke? >> Does anyone know what the current ETA of the K3 manual is? > Late June at the earliest, Michael.

Re: [Elecraft] K2 Was Fine Now Dead - getting interestring?
Allan, Fine that you found it - somewhere along the line, the base K2 was drawing excessive current and the trace acted like a fuse. I can't say what the original problem was - maybe the power connector was plugged in backwards, or something 'dumb' like that. In any case, it is a simple matter to remove the delaminated PC board trace and any charred material then repair it with wire. I would recommend that you use #20 or larger wire for that replacement trace (or use 2 pieces of #22 side by side). If you use bare wire, you can dress it along the old path and encapsulate it in a small bit of epoxy which will also glue the wire down to the board - it will be just as good as new (you can even color it green with a permanent marker and few folks will spot the repair). 73, Don W3FPR Allan Bacon wrote: Don, Thanks for your help.

Re: [Elecraft] Safely Grounded (WAS: Being ESD Safe,)
Ron, I believe there is a NEC requirement that all grounds be connected together. I have a perimeter ground around my house with an 8 ft. driven ground rod at every corner (total of 10), and all are connected with a #4 bare solid wire. The wire is also connected to the utility ground rod. This ground is then connected to the extensive grounding system in the antenna field which grounds all towers and masts. All feedlines into the shack are protected by 2 Polyphaser suppressors (one at the antenna field. All wiring into the shack area (power, telco, ethernet, and antennas) enter through a grounded copper panel and are surge protected there. I should have little ground potential difference in the shack area because of this 'single point grounding window'. If I do get a lightning surge, I trust (hope) that surge will be more gradually dissipated in the extensive ground system since it will attempt to spread the surge out over about an acre of land (yes, I used LOTS of wire), but I still do not operate with storms in the vicinity. The real point relevant to the prior discussion is that *all* my grounds are tied back to the utility ground entry point. As a second note, I know the building inspectors (at final inspection time) in this area do check with those little 'hardware store checkers' to make certain that the receptacles are wired properly. It is also common for a used home buyer to hire an inspector who will check all the receptacles in the house for proper wiring. While that practice may not be universal, one can do his own check on the house wiring with a $10 device from the hardware (or DIY) store. 73, Don W3FPR Ron D'Eau Claire wrote: Fred wrote: And secondly, which now makes much sense, that no secondary ground rods are to be used! - for one's electrical service in the home or facility. Multiple grounds, can create shock hazards. And as Don pointed out - a separate ground rod, if used at all, may be useful for one's RF antenna system, and that is all. But for ESD - the single home and facility ground connection - is the ONLY one to rely on for ESD safety. I just went through that with an electrical contractor myself. There seems to be a lot of contradictory information. As the contractor pointed out, there must be only one mains ground in a building, but that does not mean there are no other grounds! The phone company often installs a ground rod at their service entrance that is not connected to the mains ground. The cable TV company may drive in a ground at their service entrance to ground their cable. Add to that any iron water pipe that runs into the earth to the water meter, etc., and there may be several separate grounds in the home even without adding a grounded Ham antenna! Those grounds do present shock hazards if anything goes wrong with the mains ground or if the hot side of the mains circuit is exposed so that someone can touch it and any grounded conductor. That's why GFI interrupters are important in locations where secondary grounds are often encountered such as kitchens, laundry rooms, basements, bathrooms, outlets in out buildings such as garages, etc. If one grounds a Ham antenna at the at the antenna tower or mast, maybe the shack also should have GFI protection. I don't have such a grounded system so I haven't asked a contractor that question. Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Tilt Stand Bail - Violin Effect
The 6-sided K2 Case, I propose, can be put into a violin-case permanent pre-stressed condition, common to many string instruments - when they notorious Bail - is pre-stressed installed, with the Long-Screw method. Many installers have noted the post-stress bowed cover plate, after their long-screw install. "... but it straightens out when installed". I propose the whole case, and any attached pcbs, and possibly some pcb-installed components - all now share in that bowing process, during long-screw installation. Maybe the LCD display, perhaps installed L's, possibly pcb component and IC shorts, that mysteriously showed up only after a few months service? I'm sure this all sounds silly - but my "bend-bail-1/4-inch-in-a-vise" method, eliminates the distorted 6-sided K2 case condition. Hypothesis - let's say the bail is pre-bent 1/2" too long, but installer used the long-screw method and temporary compression, to get the very long bail intalled on panel. Then K2 builder installed this bowed panel on his or her K2 - and in effect straightened it out supposedly flat with body screws. Then the entire 6-sided case, would now be-prestressed violin-style by that original too-long bail. Sounds, I know, like an April 1st entry, but I propose we may have found one source of the problems of some of the past strange situations that mysteriously show up in K2's in the field. Key jacks that mysteriously last only a short time, adjustments that seem too touchy, mechanical adjustments that seem to change, front-panel buttons that don't work correctly, rheostat shafts that start to bind, speakers that seem to be distorted?, speaker coils that now bind, component lead shorts that came out of nowhere, Doubt it?

If you find the path open, you could install a TEMPORARY jumper between D10 cathode and D9 anode on top of the board to see if everything comes back to life.

[Elecraft] Modulation [K3]
I have a couple of questions on the K3. 1) I gather there is no agreed standard for digital voice modulation (at the moment). AOR seems to be using an open standard that they ascribe to G4GUO. My question is does the K3 have the capability to internally encode/decode a protocol such as the G4GUO scheme (and continue performing its other "normal" functions)? Or will it be necessary to look to an external device such as AOR's in order to use digital voice modulation? This question is a "future feature" query. 2) Amplitude modulation. I assume that the K3 does not have a 50 watt class A amp modulating the 100 watt finals. I guess the K3 fully modulates a low level stage that (with linear amplification and mixing) drives the finals. My question is does this provide the same "talk" power as the old class C AM transmitters? Or is the carrier to audio envelope proportion different (compared to the "classic" AM signal)?

RE: [Elecraft] Switching Power Supply Recommendations Wanted
The K2 isn't more sensitive than other receivers, Bob, but it seems like Hams accept a lot more background QRN generators as 'normal' than we did a few years ago. Time was, the worst source of QRN were the blasted horizontal sweep oscillators in TV sets. Now that they are fading with the evolution of flat-panel screens their demise is hardly noticed. They've been swamped with noisier sources making broadband noise such as computers and other digital stuff in the shack and, yes, switching power supplies. So it's all relative. ALL switching power supplies generate huge amounts of RF noise. SOME switching power supplies are better shielded and filtered to reduce the noise escaping the box than others. SOME Ham installations have the antenna feed line better shielded and the antenna farther from the operating position than others. SOME Hamshacks are electrically "quieter" than others, with no computer or other digital hardware running (or at least exceptionally well shielded digital stuff). SOME Ham QTHs have more background QRN than others (city vs. country - electric fence nearby or no fence nearby, etc.). All of those things add up to a whole range of environments, all of which contribute to the noise level heard in the receiver, and they all affect the subjective perception of whether a given switching power supply is "quiet" or "noisy". My linear power supply is staying right where it is under the operating table. Ron AC7AC -Original Message- Hi Elecrafters, I just sold my big, heavy linear power supply to replace it with a small, light weight switching supply that I can pack into a suitcase with my K2/100. Looking at the eham.net reviews, comments on all of the switching supplies seem to range from "great, absolutely no switching noise" to "noise everywhere", and everything in between. Given the sensitivity of the K2's receiver, is power supply switching noise likely to be more of a problem with the K2 than with some other rigs? Are there any switching power supplies that you'd recommend that work well with the K2 (and have little or no switching noise that the K2 would pick up) and are there any that I should definitely avoid?

Re: [Elecraft] #6107 - First Snag
To take a lead from my former ME associates back at Kodak's CAD group - I think the Elecraft K2 bail, as designed, has too much K and is a tad too long. Decreasing length, ever so little in a vise - makes the whole job and final installation work nicely. I think the idea of temporarily decreasing width with a c-clamp and using LONG screws, is wrong IMHO, as it places a permanent spring force on the lower cabinet cover meterial - which could cause whoknowswhat. I can't imagine operating the bail, in that compression configuration. Bench vise adjustment - takes some mechanical skill, but it works better after process is done. BAIL still operates perfectly. Not rocket science .I suspect I decreased bail's width, at ears, by like 1/4" (recall from memory) Fred, N3CSY K2 54xx Need a vacation? Get great deals to amazing places on Yahoo!

[Elecraft] K3 Bandscope
With all this discussion about panadaptors for the K3 - and even people building SoftRock add-ons already, apparently - I have just one question. Since the K3 is reported to have a built-in capability to receive datamodes, which presumably includes some kind of waterfall display, could this not be developed in some future firmware release to give a bandscope type of display in other modes? I would be quite happy to toggle between the sub-VFO display and a bandscope. Since the datamodes capability is an aspect of the K3 I'm really keen on, it would be nice to see a picture of the display with the radio receiving some PSK31, just to see what it looks like. In fact, as one of the many who was unable to go to Dayton, and whose first sight of a working K3 is likely to be when the one I ordered has been completed, it would be great to see a video like the one on YouTube, but of a K3 actually on the air, with someone going through the controls and demonstrating things like how the DSP works and the effect of the different roofing filters.

Hi Barry, When you access any of these functions, VFO B is used to change the parameter. If there are two parameters to adjust, VFO A is used as well. 73, Wayne N6KR I have been looking at the picture of the K3 and note that there are adjustable NR, NB and manual notch - but there doesn't seem to be any knob to do the adjustment.

[Elecraft] Safely Grounded (WAS: Being ESD Safe,)
Fred wrote: And secondly, which now makes much sense, that no secondary ground rods are to be used! - for one's electrical service in the home or facility. Multiple grounds, can create shock hazards. And as Don pointed out - a separate ground rod, if used at all, may be useful for one's RF antenna system, and that is all. But for ESD - the single home and facility ground connection - is the ONLY one to rely on for ESD safety. I just went through that with an electrical contractor myself. There seems to be a lot of contradictory information. As the contractor pointed out, there must be only one mains ground in a building, but that does not mean there are no other grounds! The phone company often installs a ground rod at their service entrance that is not connected to the mains ground. The cable TV company may drive in a ground at their service entrance to ground their cable. Add to that any iron water pipe that runs into the earth to the water meter, etc., and there may be several separate grounds in the home even without adding a grounded Ham antenna! Those grounds do present shock hazards if anything goes wrong with the mains ground or if the hot side of the mains circuit is exposed so that someone can touch it and any grounded conductor. That's why GFI interrupters are important in locations where secondary grounds are often encountered such as kitchens, laundry rooms, basements, bathrooms, outlets in out buildings such as garages, etc. If one grounds a Ham antenna at the at the antenna tower or mast, maybe the shack also should have GFI protection. I don't have such a grounded system so I haven't asked a contractor that question. Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 Was Fine Now Dead?
Alan, You are reading the schematic correctly - yes there should be a connection between the cathode of D10 and the anode of D9 (check to be certain they are connected with an ohmmeter first). If you find the path open, you could install a TEMPORARY jumper between D10 cathode and D9 anode on top of the board to see if everything comes back to life. If that restores full function, then remove the board to find the damaged PC board trace or (more likely) the bad solder connection. Nothing in your measurements indicate a bad diode to me. A diode conducts positive voltage from the anode to the cathode (hint: follow the arrowhead on the diode symbol), but blocks a positive voltage in the opposite direction. 73, Don W3FPR Allan Bacon wrote: I started tracing 13.8 V from the power source Input 13.8 V Diode D10 Cathode 13.8 V Anode 0 to ground as per specifications Diode D9 Anode 0 V Cathode 0 V So, it seems power is not getting to the D9 Diode From the schematic on page 64, it looks as those are the only components on the trace from power injection to the KPA-100 to the "Aux 12V" at J4 Here is where my lack of knowledge shows up - 1.

Re: [Elecraft] #6107 - First Snag
One of the most clever recommendations that I remember from those discussions a few years ago was to wrap a few turns of wire from one bail end to another and insert a short rod of some type and twist it "tourniquet style" to slowly draw the ends inward until they are drawn together enough to allow it to be attached. Or -- you could dispense with the bail altogether (as I did) and cobble together some taller 'feet' for the front of the radio so that the front sits up about an inch or a little more above the surface upon which it is resting. May not be too good for portable use, but for home use on a desktop it works very well. 73, Dale WA8SRA K2 #3039 Mark Bayern wrote: IMO, the bail is the most difficult piece of the assembly.

The spring force was so great it warped the cover piece. I took it out and 'gently' bent it inward a bit.

Re: [Elecraft] K2 ATU
Tim, Even when the KAT2 is attached, you can still hear signals through the base K2 antenna jack - that is NOT a problem. If you cannot receive through the ANT1 or ANT2 jacks on the KAT2, the problem must be with the KAT2. Since I presume it worked before, look for the easy things first, like a break in the input coax or improper seating of the crimp pins in the connector. If you set the menu to ATU CALP, you should be able to make a continuity check from the input coax center conductor to the center conductor of ANT1 or ANT2. 73, Don W3FPR Ellam, Timothy St. J. wrote: I have a problem which I am sure is my own error, but for the life of me I cannot seem to find the fix.

Allan, Was that J5, the 3 pin connector point (no header is normally installed there) on the RF Board near the front center (near the control board)? If you did everything correctly, it should have no effect on the K2 power-up condition. If you wired to some other place than the 3 pin J5, remove what you added and try to discover what the error is. It may have been something that inadvertently happened, and not at all associated with your additions - in that case, voltage measurements are in order. You may have had a pin pushed back on the AUX DC connector from the KPA100, and it is no longer making contact with P3 on the RF Board - insert the crimp pins into the housing correctly if you find that to be the problem. Is the KPA100 ribbon cable properly attached to the control board? These are but a few starter questions. 73, Don W3FPR Allan Bacon wrote: > K2 4670 with 100W and all options was working fine. > > > > Per the recommendation of Microham, I added a speaker jack from J5 to a > stereo plug on the back of the case and now the unit will not power up on > the KPA-100 > > > > When I plug in power to the low power jack, the unit is OK, but will not go > to high power. > > > > Any ideas? > > > > Thanks, > > 73, > > Allan Bacon > > W6GBG > > > > ___ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.

Re: [Elecraft] #6107 - First Snag
Fred, I believe you are advocating bending a permanent reduction in the bail width with the vise (if not, I have misunderstood you). I do NOT recommend doing that since it results in a loose fitting bail which will be 'floppy'. Using a vise or a clamp to squeeze the bail temporarily while installing the screws is OK, but permanently distorting the bail is not OK IMHO. 73, Don W3FPR Fred (FL) wrote: VISE - that is the trick. Just force some (SOME) of the spring width out of the metal item. It works fine, if you just squeeze it down a small amount - do it in stages, as it would be hard to make it wider again in a Vise.

Re: [Elecraft] Dead K2
Kristina, You will just have to continue measuring things until you discover the root cause. Did you measure the resistance at the power plug with the power switch ON? Try the checks below (in order until you find the source). Measure the resistance to ground from the cathode of D12. You may find it quite low (indicating a short). Remove the control board and check it again - if the resistance increases, look for the problem on the control board. If not on the control board, remove the heat sink and then recheck - if things are OK with the heat sink removed, check the thermal pads. If you still have not found it, the 'hunting' gets more difficult. Use the schematic to follow the path of the 12V voltage line - it starts at the lower right corner of RF Board sheet 1, and goes to the regulators on the control board, and various places on the RF Board (mostly on sheet 4). Check those paths thoroughly, even if it means removing some components to see which side of the component the short is located. Remember that the most likely cause is a solder bridge (connecting 2 points that should not connect together) so a VERY careful visual inspection may reveal the problem source. Work in an orderly manner - a short on a power line is difficult to find because the PC traces seem to go everywhere and it is difficult to isolate them - expect some frustration in the process. 73, Don W3FPR Kristina Wright wrote: OK, here's what I've done so far: checked the resistance from the power plug to ground, the meter read infinite resistance. Also checked the voltage at the same and got 12 volts. Then I measured the voltage at the cathode end of D10 and got 12 volts with the power switch on and off, but at D12 I got nothing with the power off and 0.7 volts with it on. Obviously the fuse is being tripped, but I still don't see any shorts (yes I inspected the whole board carefully). Thanks for the help so far, any more ideas? 73, Kristina, KE7LUC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] SoftRock Lite for K3 IF application
Good Morning All, A number of hams have ordered a SoftRock Lite kit for the K3 IF application. The SoftRock Lite for this use includes a 32.768 MHz crystal to give a center frequency of about 8.191 MHz. This would require that the soundcard used for the application sample at 96 kHz to span the K3 IF in a good way. The resulting IF frequency coverage would be from about 8.143 MHz to 8.239 MHz. There may be some design issues with the kit I am providing relating to the signal and Z level at the IF output of the K3. This morning I built an example of the SoftRock Lite for the K3 IF use and as I type this I have it playing on this PC using the Rocky 3.2 software. This SoftRock example needs a better test than I can do with my limited test equipment. Is there someone on the list that already has a pre-production K3 and would be interested in evaluating the SoftRock for the K3 use. If so, I would be happy to send them this unit at no cost if they would give it a try, help work through any interface issues, and report their findings, (good or bad), to the list. Please contact me at [EMAIL PROTECTED] if interested. Thanks and 73, Tony KB9YIG ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] #6107 - First Snag
Jim, Install the first foot and tighten it, and then either: 1) Install the second foot using 'builder provided' long screws - after things are lined up and tightened with the long screws, remove the long ones one at a time and replace them with the proper screws. 2) Use a clamp to compress the bail - compress only enough to permit the screws to be installed, the bail must remain 'springy' or it will be loose and rattle. I use both methods - the clamp head takes a bit of 'figuring' so you can tighten the screws with the clamp attached, but you can combine both methods and make things easier. 73, Don W3FPR Jim Murray wrote: Hello All, Progress temporarily halted by (who would ever guess) a tilt bail.

RE: [Elecraft] K2 ATU
There is a RF cable from the ATU to the mainboard. The auxbux is detecting the ATU so that's connected, but the RF most likely is not. The RF cable plugs into the main board at RF-P6. Do not connect it to RF-P3, the battery connector!

Re: [Elecraft] #6107 - First Snag
Jim: The way I've successfully done it, and with NO(!) effort, is to install the feet/bail using much longer (say 1") screws... TIGHTEN things down and then, one at a time, replace the long screws with the proper ones. Using the longer screws makes it very easy to get everything in place BEFORE you have to torque things down. Of course, you'll have to supply your own (4) long screws, but it's certainly worth the effort. 73, Tom Hammond N0SS At 10:25 PM 5/24/2007, you wrote: Hello All, Progress temporarily halted by (who would ever guess) a tilt bail.

RE: [Elecraft] #6107 - First Snag
Oh, yes, I remember. That blasted bail! We can buy pre-wound toroids - someone needs to sell a pre-mounted bail! I think I put my bail in a vise and tried to squeeze it down a bit. I also used some of the longer screws to get things started then swapped them out once it was together. - Keith N1AS - - K2 5411.ssb.100 - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Bayern IMO, the bail is the most difficult piece of the assembly.

[Elecraft] K2: sending PSK31
Following up on my earlier question, I can report that the minimal PSK31 interface described in the Elecraft Application Notes actually works. For receive, I got a stereo cable with plugs on each end, running from the K2 speaker jack to the computer line in, and for sending a stereo cable from the computer earphone output goes to an 8-pin mic plug with two resistors in it, 10K and 1K, as a voltage splitter. Transmit is keyed by vox. No isolation tranformers, no USB mic converter. Computer is a MacBook, software is Cocoamodem, and they work just dandy, though I'd expect any other computer-software combination to work, too.

Re: [Elecraft] Being ESD Safe,
Ron, Don - I learned a good deal more clarification today, about ESD Safe - and one's potential house wiring situation. Thanks. Looks like one has to verify, with available testers, and electricians if need be, that their facility and shack and home, are wired correctly and that the SINGLE GROUND, provided at the mains entrance to the facility, is correct and operational as it should be by NEC code. And it is the ONLY ground connection, relied on. And secondly, which now makes much sense, that no secondary ground rods are to be used! - for one's electrical service in the home or facility. Multiple grounds, can create shock hazards. And as Don pointed out - a separate ground rod, if used at all, may be useful for one's RF antenna system, and that is all. But for ESD - the single home and facility ground connection - is the ONLY one to rely on for ESD safety. Whether that is established, and working is the chore at hand. The IEEE Hospitals multiple-grounds problem, was a case of new and old hospital facilities, where they found multiple ground levels existing in different places in the overall hospital. This resulted in patients being exposed to differing ground-levels, all impacting on the patient's monitoring equipments. IEEE reported patients may have died from this situation - and indicated possibly no one (MD's & staff) realized this had happened. In our home, I hired an electrical contractor to verify the condition of my electrical plugs, and breaker box setup. He found several problems - and fixed them and brought them back into compliance with current NEC code. They even pulled the meter - and "lubricated" the mains HD cabling connections coming into the breaker box. (pulling meter, requires an electrician, and action by power company, as meter safety tag has to be broken) The work & certification by a licensed electrician, is especially important when electrical work is done in a facility - for both personal safety, and to ensure continued insurance coverage on a home or facility. It isn't a common sense, or seat of the pants do-it-yourself operation. There is a method in the strictness of the NEC.
