[Elecraft] News from Visalia!
How would $400-450 for a 200-300w linear sound? I am building up such a linear amp 12w --> 200w on 2-30 MHz. If it tests out well, I am thinking their may be a market for this. I understand that the FCC has to accept the unit, but I wonder if it is only available as a kit if that applies? This is a 28-volt transistor so a 28 volt 20A supply is needed Two could be combined for up to 600w but would require 40w drive and a 40amp PS. No competition for the new 500w linear from Elecraft -- Message: 44 Date: Sun, 18 Apr 2010 09:50:25 -0500 From: "John Harper" Subject: Re: [Elecraft] News from Visalia!

Re: [Elecraft] KPA500
I think I overheard at Visalia that the KPA500 draws only 1 kW from the AC power line with 500W out. It uses a high-efficiency toroidal power transformer. I doubt that a switching power supply would do any better than that. The total weight is about 22 pounds I believe. Less than many transceivers.

Re: [Elecraft] Grounding negative side of power supply?
This appears to be a question from January 20, 2010, so it is a little late, but a person never wants to connect the ground rod of the K9AY antenna or any other small or low receiving antenna to the mains ground. First, it would kill the advantage of having the antenna. If you are going to do that, don't bother installing the antenna. It will hurt the antenna in more than one way. Second, it is not necessary for safety. It is not a large tall structure and is not likely at all to be involved with a direct lightning hit, and even if it were hit the ground at the cable entrance to the house would provide all the required protection. The shack ground and the antenna entrance ground should be bonded to the mains, but the K9AY or any other low noise receiving array must have an isolated ground. The cable leaving the receiving antenna should be buried, should have common mode isolation, and should be grounded at the house entrance to a ground that is bonded to the mains ground. 73 Tom - Original Message - From: "Robert Mcgraw" To: "Bill Coleman" Cc: ; Sent: Sunday, April 18, 2010 10:35 PM Subject: Re: [Elecraft] Grounding negative side of power supply? Yes, do provide a driven ground for the K9AY receiving antenna. This is required for lightning protection. AND be sure to bond this ground to the AC mains ground for the house. Failure to do this will produce a voltage difference or step voltage between the two ground during a nearby lightning strike. The voltage difference can be enough to damage or destroy the radio connected between the antenna and the AC power. AND, bonding of all grounds to a common point is a requirement of the NEC. Remember, lighting has traveled through several thousand feet of air. A balun will offer little to no protection in this regard. Now placing a choke balun or a 1:1 current balun at the feed point will reduce common mode noise on the coax feed line. 73 Bob, K4TAX > > On Jan 20, 2010, at 11:47 PM, Richard S.

[Elecraft] Elecraft CW Net Report for April 18th & 19th, 2010
Good Evening, Both bands were noisy with some QSB on them each. QSB was worse on 40 meters as was the QRN. But we got some folks through the hash. Brian tried to make each of the three nets today but he is just too close to work me on 20 meters. Once the solar influence steadies the bands should be much stronger. While we were running the nets a CME was striking the ionosphere. The weather reports from across the country were of rather pleasant spring days. I too had sun with a temperature which rose to 67 degrees. I could walk outside in my t-shirt and tempt the biting flies. They are not yet out in force but a few more days like this they will be. Luckily the next week's forecast is for rain. That means I am outside less and they don't fly so rapidly. Since they only live for a few weeks that is just fine with me. Once they die off the rest of the year is very nice. On to the lists => On 14050 kHz at 2200z: K1THP - Dave - CT - K3 - 686 N0TA - John - CO - K3 - 994 W0CZ - Ken - ND - K3 - 457 K4JPN - Steve - GA - K2 - 1422 W0RSR - Mike - CO - K2 - 5767 AB9V - Mike - IN - K3 - 398 KM5PS - John - AR - K3 NO8V - John - MI - K3 - 820 On 7045 kHz at z: NO8V - John - MI - K3 - 820 N0TA - John - CO - K3 - 994 * QNI # 125 * W0RSR - Mike - CO - K2 - 5767 K0DTJ - Brian - CA - K3 - 4113 AB9V - Mike - IN - K3 - 398 N0AR - Scott - MN - K2 - 4866 ** QNI # 245 ** N7KRT - Jeff - TX - K2 - 5471 W0CZ - Ken - ND - K3 - 457 I spent some time this week cutting and splitting wood but the more pleasant weather means I do not need to heat the house so much. However, the more wood I can prepare now the less work I will have later. It is much nicer to do this kind of work during the cooler days than it is to split and move wood during the heat of summer. But until I have ten cords sitting around the house covered and drying I am not satisified. This year it got to be very close. I was only a few days from running out when I had a chance to cut enough to get by. I think I have enough to get through until fall. Yes, I heat during the summer too. At least one good fire every month to dry out the house and get rid of the chill. I am hoping the recent solar activity will provide a good week of steady and strong propagation. During the last week propagation was rather weak and unsettled. With all the activity there was never a chance for it to calm down enough to make propagation good. But the sun has no spots right now even though the prominences are jumping all over. After the long hiatus the sun is awakening. Predictions are all over the map though so it could be the best cycle ever or just ho hum. Only time will tell. Until next week stay well and keep your stick on the ice :) 73, Kevin.

Re: [Elecraft] P3
I disagree. The radio I built doesn't "rely" on an external computer. The Pan adapter I built and use with it does. Tell me, how is the P3 firmware going to be upgraded? Magic firmware pixies? The computer I built for the task doesn't have "questionable hardware integrity". It's top of the line and will run away from any factory built machine from ANY company, yes, including the Ipod manufacturer. Which flaky operating system are you referring to? I run three separate OS's on my machine. Right now I've got WinXP Pro 32 bit, Windows 7 64 bit, and Linux 64 bit installed. Pan adapter works with all three but then I installed REAL serial ports. People have trouble with the USB-serial adapter drivers and we blame the operating system? I'd be willing to bet most USB adapter problems are actually pilot error. You did follow the directions and install the drivers before you plugged it in the first time right? You did fully uninstall the drivers before trying a new version right? The computer/soundcard/LP-Pan/software combination is WAY more flexible and powerful than anything Elecraft can do with the P3. Must be a reason why every time the P3 comes up, the first thing people want to do is turn it into a computer by hanging a mouse and keyboard off of it. Makes one go Huhmmm???

[Elecraft] RTTY using DATA mode on K3 (FIXED!)
Hi Everyone, Thanks to all the good feedback on this list, my problem is solved. As many people pointed out, the Mark frequency in MMTTY has to match the pitch setting in the K3. I checked the K3 (thanks to those who showed me how) and it was 2125 Hz as expected. I checked MMTTY and it was 473 Hz (where the heck did that come from???). I reset the value in MMTTY to 2125 and was able to print RTTY in data mode with no problem. A few minutes later, had my first RTTY QSO with the K3. Worked perfectly. So, there was nothing wrong with the K3 and the only issue was the configuration of MMTTY. I am very greatful to all of you who responded and gave me the information to solve my problem.

Re: [Elecraft] KPA500 active devices!!
The fcc requires amplifier gain to be 15 decibels maximum for any amatuer radio amplifier.

Re: [Elecraft] RTTY using DATA mode on K3
G'day, My AFSK A pitch is set to 1445Hz. MMTTY (in Logger32) is set to default to 1445Hz. When I start up MMTTY the frequency markers on the waterfall are appropriate for 1445Hz paired tones. If I activate the DUAL PB filter the filter is also matched to the tone pair. If I change the K3 pitch setting then the DUAL PB filter changes to the new pitch frequency pair. Without DUAL PB activated I can receive and transmit anywhere within the displayed waterfall, dependent upon the IF bandwidth selected simply by clicking on the desired signal. With DUAL PB activated I can only receive at the pitch frequency pair and tuning to a new signal requires use of the VFO. As expected. With NET ON the MMTTY TX tones follow the RX setting, with NET OFF the TX tones remain fixed to the MMTTY pitch setting, in may case 1445Hz and the receive can be anywhere in the waterfall. This is naturally how one can work narrow split or answers callers off frequency, or at least I do. Now, there is a catch if you have CONFIG: AFSK TX - FIL ON. The K3 wraps a 400Hz DSP TX filter around the selected TX pitch pair. If you then try and TX anywhere outside that 400Hz filter there is no output. Like the DUAL PB this filter is shifted to match the K3 pitch setting. The default setting is OFF. In AFSK A mode the K3 displays the RTTY Mark frequency which means when I click on a spot the radio is tuned to the spot. This will not happen if you use DATA A, you have to offset the VFO manually to go looking for the signal in the waterfall. For what it's worth. Oh yes, it's all in the handbook!

With MMTTY, it's possible to net the TX tones to the RX tones anywhere on the watefall, but if the TX tones are way off the rig's expected tone frequencies, they are filtered away.

Many of us HAMs are accused of it. Good things grow under rocks. It would be the dark side! The issue is assuming what is sent on the internet is private? No way.

Mistakes can happen. Whatever one writes, consider the consequences and don't forget: it can be found on the internet. If you don't want it known, send it out USPS. If someone else should not follow one's perceived protocol: s happens. No one is perfect. I am not, Don is a lot closer. I have mistakenly sent out things I didn't want to or sent them to the wrong recipient with no malice intended. I recently did so. The wrong recipient told me he knew they weren't for him so just deleted them. Then he told me the last one I wrote was quite good. Oh, well. S happens. I can't get it back. I screwed up (again!) and could not retract the simple but very bad mistake. I didn't dwell. Moved on to this issue. Let's all lighten up and be forgiving because none of us is perfect.

And why max out at 15 amps? My house was built in 1994, and has 20 amp circuits and wiring throughout. 15 amps is likely only the limit of the plug. I have successfully run my camping trailer's air conditioner off one of these outlets. I've measured it at 1400 watts draw at about 12 amps. There are hair dryers that draw more current than this. At 1500 watt draw is not unreasonable from a 120v outlet. Ironically, the only 15 amp circuit in my house is on the 240 volt outlet for my current amplifier.

I have been reading other friends with > the same problem. > I want test another one. > What is your recomendation? When I got my K2 back in 2001, I was using a linear power supply. A few years ago, that power supply died when the power transformer primary opened. I bought a Samlex 1223 supply to replace it. I was impressed with the size of the unit, and it had no trouble supplying my K2/100 to full output, even on 160m. However, I was disturbed to find numerous spurs were audible on my antennas on 160m. The loudest of these was near 1845 kHz, about an S7 on the K2 S-meter. Note that the location and strength of the spurs varies with supply load. First, you need to identify if it is the Samlex that is causing the noise. I did this by momentarily turning the supply off. The K2 (and K3) draw little current in receive, so you should have about 2 seconds of receive before the radio goes dead. If the noise moves away rapidly or disappears completely, it is likely the power supply. I would recommend you try to find the strongest noise source for the load you have while receiving. Note that these switching power supplies will shift the intensity and location of their birdies when the load changes. The SEC-1223 does not have a filtered AC cord. I used a snap-on toroid core to determine that the AC line could use some filtering. If your AC receptacle is already filtered, you can go directly to the DC output lines. I found that putting a snap-on ferrite core around the power cord reduced the spur to an S5 indication. A similar reduction could be had by placing a snap-on ferrite around the power output leads. My first modification was to de-solder the white and black power cord jumpers inside the unit in order to slip on seven FT50-77 toroids. After this modification, the spur was reduced to an S5 indication. Since that wasn't sufficient, I then made a modification similar to that designed by ZL2DF and published by N0SS: http://www.n0ss.net/samlex_1223_rfi_mods_from_zl2df.pdf My unit was different from ZL2DF, in that it did not have the screw / compression power terminals. Instead, my unit used two binding posts that were soldered directly to spade terminals on the PC board. After pulling out the PC board, I removed the spade terminals. I replaced these with 16 gauge wire fed through eight type 43 ferrite beads for each lead. The wire is small, but it is the largest that would fit through the beads. the output terminals are bypassed across each other and to chassis ground with .1 50v multi-layer ceramic caps. After this, the spur at 1845 kHz was just audible. At night, atmospheric noise covers it up. This supply was originally designed to work with VHF/ UHF gear, and likely does well. With minor modifications, it is suitable for use with HF gear.

Using the CocoaModem Config window works well, too. There is quite a bit of eye-balling to the filter setting. Of course, if you don't pay attention, you may find yourself on the wrong side of the passband. The final step that I put into my filter calibration is to use my ears and cycle between opposite sidebands (using CW REV) and make sure the settings sound reasonable with each other, and they look good on the spectrum display. If one of them sounds off, I'll jog the BFO frequency one tick one way or the other and cycle through again. Doing it this way, I'm managed to get the filters within 20 Hz or so of each other. I've got a blog entry that has a bit more information on how I set up my filters: http://boringhamradiopart.blogspot.com/2010/02/configuring-elecraft-k2-crystal-filters.html I don't use the variable bandwidth filter much more than 1 kHz wide, because it starts to get asymmetric and makes for pretty harsh listening. I use the OP1 filter on SSB and use the DSP for high-QRM situations like in contests. (Of course, I'm using KI6WX's "1.9" SSB filter, which is about 2 kHz wide, but has less ripple than the original KSB2 2.0 kHz filter) Bill Coleman, AA4LR, PP-ASELMail: aa...@arrl.net Web: http://boringhamradiopart.blogspot.com Quote: "Not within a thousand years will man ever fly!" -- Wilbur Wright, 1901 __ 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

For the K9AY, your best bet is to make sure the antenna ground and the coax ground are completely isolated. I do this by magnetically coupling the coax with a 9:1 transformer. Otherwise, common-mode noise can move out the shield and be picked up by the antenna.

Re: [Elecraft] News from Visalia!
"Sounds trivial to me. You must have *some* switch closure or logic signal that activates the PA. Lock out all tuner adjustments when the PA is on." Or conversely, disable the amp before tuning starts. That's the way my MFJ-998 autotuner works. The amp-enable signal goes thru the MFJ-998. So when the tuner wants to tuen, the first thing it does is interrupt the amp-key line.

It's pretty basic stuff Guy. Look at what happens in this MRF150: http://www.w8ji.com/demonstation.htm It would be nice if there was a free lunch and we could magically buy a device that didn't care about the load and gave reasonable operating efficiency and good IMD with any impedance from perfect to a 3:1 mismatch, but it isn't possible.

Re: [Elecraft] KPA500
See my earlier note as to one reason it was chosen. Elecraft learned from the K2 about being a good player in a multi-TX environment (which can just be neighbors). Also, the 60V supply is providing no current when key up, and needs to go to full output on key down- apparently this is less of a problem with a linear supply than with a switcher. And of particular significance to CW ops. BTW, much of what I'm writing is my repeating what I was told or heard, and none of it is binding on Elecraft, and is subject to my misinterpretation, as well as changes down the line. The amp is still in prototype, and has lots of testing to endure before it's solid.

Re: [Elecraft] News from Visalia!
Date: Sun, 18 Apr 2010 17:22:02 -0400 From: Guy Olinger K2AV The one possible work-around is an Elecraft tuner that will not work unless hooked up to an Elecraft amp and a Kx via proprietary protocol so it knows whether it is QRO or not and can seamlessly drop out of QRO for tuning. Something like how the K2 and the KPA100 work. That's what the TBD ACC2 connector could do, provide handshaking for an external ATU so that it would be operated in low-stress configurations. That ATU doesn't have to come from Elecraft, though. LDG has certainly made automatic tuners that work with Icom's (more or less undocumented) tuner protocol, even making model numbers sorta match i.e. AT-7000. 73, doug back home again, CA 198 to CA 25 to slab. __ 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

Re: [Elecraft] News from Visalia! (:-))
From: "Terry Posey" Date: Sun, 18 Apr 2010 16:16:58 -0400 I have already acquired a high duty cycle, low distortion, 1.5KW amplifier years ago. Now I would like a small, light, and portable HF+6-meter amplifier for DXpedition duty. I personally will not consider ANY amplifier that cannot Perform on 6-meters in a small stylish, compact, light, and low distortion package. Your mileage does vary. Interestingly M-Squared was showing a VERY small high-power 6M amp. I didn't pay a lot of attention and can't locate the sheet I picked up about it, but 6M folks might want to check it out. Given the size and direction of the KPA-500, I think it'll be in demand. 500W on RTTY with DXpedition/contesting duty cycles make me happy. My IC-2KL with a commercial switching supply weighs 25 pounds (I'm home now), and I thought that was pretty good. It's also larger (both pieces together). 73, doug __ 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

Re: [Elecraft] News from Visalia!
On an empathetic note... Can Elecraft come up a price-appropriate tuner design that will survive hams at 500 watt RTTY? In the midst of trying to concoct a remote home brew tuner to put 160-30 meters on a 135 foot end-fed wire, the calculator and equations starting telling me that voltages and currents that would have to be switched under power could run over 10 kV or 20 amps, depending on frequency, at 1.5 kW. IF there were a bullet-proof, ham-proof way of insuring that contacts were NEVER, EVER switched under power, some things could be done. But I can't figure out how to keep ME from doing that when I'm really stupid at the end of a contest. There is a point at which bulletproof tuner designs seem to warp into an entire new expensive component universe. Depending on the engineer and personal or commercial risk tolerance, and whether that might be RTTY or not, that power level is 200-400 watts. After that you are talking Collins Radio kind of commercial/military grade designs with motors, vacuum relays and capacitors. Less than that and one is frying stuff that is perfectly satisfactory at 200-400 watts. The commercial risk is obvious. Burned contacts will always be blamed on the manufacturer. If he can't design something that can't burn, for a price a customer is willing to pay, what's the point. Go out and price a pair of motor driven vacuum variable capacitors big enough to cover the variation on 160m and with the voltage rating to stand up to tuning antennas at voltage nodes. Gak. Sigh. Kind of like the sound barrier, not impossible but definitely a new mode beyond it. The one possible work-around is an Elecraft tuner that will not work unless hooked up to an Elecraft amp and a Kx via proprietary protocol so it knows whether it is QRO or not and can seamlessly drop out of QRO for tuning.

Re: [Elecraft] KPA500
Any switching supply today and one that's "worth it's salt" should operate satisfactorily from 100 VAC to 250 VAC.

Re: [Elecraft] RTTY using DATA mode on K3
Something that caught me out once or twice is that the PC's audio output should be close to the K3's tone settings on RTTy (can't remember if this is DATA or AFSK modes - possibly both). With MMTTY, it's possible to net the TX tones to the RX tones anywhere on the watefall, but if the TX tones are way off the rig's expected tone frequencies, they are filtered away.

Re: [Elecraft] In Reference to: k2 pll and ref osc issues n0xdb
I certainly agree with everything that has been said in Don's favor and defense, and it would be a tragic loss if he were to leave the reflector permanently. Personally, I suspect he will probably reconsider and come back at some point in the not-too-distant future, and I hope that he does. IMO, Don did nothing wrong or deserving of censure. Opinions have been expressed, some perhaps in a less-than-artful manner, but it's over -- and hopefully once everybody calms down, Don will be back with us. Hopefully.

Also, an ALS600 with the Linear Power supply, AD5X Full Break In mod and an external bandswitching accessory plus an MFJ998 would come in considerably under the $2,000 price. I should know. I own this configuration and it works wonderfully at a total cost of just under $1,800 :) Matching boxes are nice, but they are not worth that kind of money for that power level. 500 watts in kit form with a under $1,100 price point makes much more sense in today's economic environment, with the added advantage of me being able to build and service it (although the Ameritron is very simple inside, easy to service and I don't have to build it, for two hundred dollars more!). Sorry, but the Kool Aid seems to be starting to taste a little bitter. -lu-w4lt- lu, I understand how you conclude your personal equipment druthers - and there can be no criticisms for those choices. Let me suggest; however, that there is an "iron triangle" that most people consider as trade-offs for purchases, either consciously or subconsciously : 1) Performance, 2) Style, and 3) Cost. In general we all seek to maximize performance in whatever we wish to acquire or purchase, whether it be power level, duty cycle, weight, distortion, and HF and 6-meter band coverage. I will argue that Style is also an issue for everyone on some level - do we really need to have any of our cabinets painted? What about knobs? Must they be black? Knurled? Plastic? Metal? Ultimately, Performance and Style are phase-locked to COST. The more you demand of Performance and Style, the higher the Cost must be. Considerations of 1) Performance, 2) Style, and 3) Cost, send our personal choices in the directions that suit us as we individuals deem best. Those choices have nothing to do with the taste of anyone's Kool Aid. I have already acquired a high duty cycle, low distortion, 1.5KW amplifier years ago. Now I would like a small, light, and portable HF+6-meter amplifier for DXpedition duty. I personally will not consider ANY amplifier that cannot Perform on 6-meters in a small stylish, compact, light, and low distortion package. Your mileage does vary. 73, Terry K4RX __ 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

Re: [Elecraft] Voice Announcement
I must add a few words about my blind Topband buddy K3UL. Bob is an excellent operator and one of the top low band DXers on worldwide with over 300 confirmed on 160. He even goes on occasional DXpeditions to ZF2UL. Bob also does some of his own tower work even though he's totally blind. Here's an interesting comment from Earl K6SE (now SK) from a few years ago: http://lists.contesting.com/archives//html/Topband/2004-03/msg00213.html "If you follow these rules, you can very accurately design a shunt feed system. Of the many requests I've had, one I remember best is Bob's, K3UL. He asked me what the parameters might be for his tower (shunt wire spacing, tie point and value of gamma capacitor), so I modeled his structure and e-mailed the details to him. Bob installed the shunt feed on his tower and e-mailed back to me that it was right on the money. What was so gratifying about this is that Bob is a blind amateur and did the work himself. He now has one of the biggest signals on Topband from the east coast here on the west coast." The next time you think you can't do something...just remember Bob! 73, Bill W4ZV Bob Garrett wrote: > > Toby et al, > > Like Gary Lee, I'm a blind ham and have been using the K3 quite > successfully > for the past two years.

[Elecraft] Voice Announcement
Gary and Bob, I was not aware of any programs available like you have just posted. I think that is just great, and my hat is off to you both being sight impaired and operating the K3. The thought did come to me that someone who is sighted could set the rig up and get it ready for operation, but without the voice announcement you could get very confused in a hurry. So I am glad that at least some of the functions are capable of being announced. Most of the Icoms will announce the s meter, frequency, and mode, but will not announce the individual function buttons. Some of the other brands do this also. I stand corrected, and glad you fellows came out with your personal operating situations with the K3.

[Elecraft] AFSK in DATA A mode
When you first select AFSK the filters will be set to dual pass-band with narrow widths. Tuning is sharp. The tone pitches are set in the CONFIG menu, I believe. You can change the filter setting to anything you want. My K3 will not transmit PSK31 in LSB/USB, just a steady tone. (I do have MIC+LIN IN set to on in Menu and this may cause this. Not sure.) I must be in DATA A to transmit.

Re: [Elecraft] RTTY using DATA mode on K3
Hi Derek, When using a computer and sound card to drive the K3 in any digital mode, your data mode should be set to DATA A. Somebody will correct me if I'm wrong, but I suspect that's your problem. DATA A mode is basically equivalent to the USB/LSB position, except that equalization and compression are disabled.

Re: [Elecraft] RTTY using DATA mode on K3
I'm using the same setup. Check the K3 pitch (Hold the "Spot" button) and verify that it's the same as the Mark setting in MMTTY. I used 915 Hz since it's much easier on the ears and I can almost tune signals by ear now close enough to demodulate. The downside to the lower tone is the possibility of more IMD on transmit. Turn off Net and AFC. I tune the K3 frequency using the MMTTY X-Y display. (If I could turn off the waterfall I would.)

Derek, I wouldn't have said that DATA modes give you better performance necessarily, but using AFSK A gives you the ability to use a number of RTTY-specific features on the K3 that are not available in SSB mode. In AFSK A, the default filter settings are much narrower than in LSB, so you don't have as much freedom to tune signals using an arbitrary audio frequency. Check that the PITCH setting on the K3 in AFSK A mode is consistent with the Mark setting in MMTTY, and that when you tune in a signal you tune such that the received audio mark tone lands on that audio frequency. To start with, I'd suggest that you turn MMTTY's AFC off, and use the K3's tuning knob to tune in signals - don't click with the mouse in the waterfall or let AFC tune to nearby signals. 73, Rich VE3KI __ 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
Re: [Elecraft] k2 pll and ref osc issues n0xdb
I'll stop pouring gas on this after this post, but to reiterate a few things: >Name and call sign is not personal information, it is a matter of public record < It's the principle involved, not the happenstance that Don simply printed something about this person that's a matter of public record. The problem is posting personal information about another lister _without his or her explicit consent_ regardless of where that information was obtained. If that's ok sometimes and not others, where do you draw the line and when? Who draws it? Should be easy to see that this can get ugly fast - That's why violating privacy in this manner on a public forum is (or should be) a no-no as a matter of principle. The fact that this has to be explained is something I find a bit worrying. >It does not take much research in the archives to see that a lot of anonymous posts are trolls, which is why it grinds on so many.< I see no evidence here that the original poster is a troll. This would have to be demonstrated first before I would support censuring him as such. Instead, he merely wasn't posting his name probably for his own reasons. If he were otherwise engaging in troll-like behavior that would have been another matter, but I see no evidence of that so far. It's certainly not grounds for violating his personal privacy. >He should not have to defend himself. < The way I see it, no one should be above the rules. You break em, you get popped on the wrist, end of story. I see no reason for anyone to get special treatment. But that's just the way I see it, how I was raised, etc. YMMV.

[Elecraft] CONFIG: WMTR Settings
I have calibrated the WMTR LP and WMTR HP settings over and over again until I am ready to pull (what remains of) my hair out. This can be a frustrating exercise in futility if you let it get the best of you. First, it is necessary to let the K3 warm up for an hour to two before starting the 5 watt and 50 watt calibrations on 20 meters. These settings are heat sensitive. One of my K3s has a LP of 045 and HP of 035. My other K3 has a LP of 089 and HP of 090. There is no standard reading for these menu parameters. Once these menu parameters are set for a 5 and 50 watt reading on a accurate external wattmeter, they will probably not read exactly 5 and 50 watts the next time you check at a later time. When the K3 POWER is set to 100 watts, the actual output will be somewhere between 93 and 97 watts on the external wattmeter. This is normal unless the menu parameters are fudged. I also find it necessary to do the WMTR LP and HP calibration BEFORE doing the TX GAIN CALIBR ATION.

Re: [Elecraft] News from Visalia! (:-))
I agree: I can get an ACOM 1010 (admittedly, with a tube) around (below) that that price with the handy TRI tuning and 800w to do the same thing, with paperclip reliability to boot. Also, an ALS600 with the Linear Power supply, AD5X Full Break In mod and an external bandswitching accessory plus an MFJ998 would come in considerably under the $2,000 price. I should know. I own this configuration and it works wonderfully at a total cost of just under $1,800 :) Matching boxes are nice, but they are not worth that kind of money for that power level. 500 watts in kit form with a under $1,100 price point makes much more sense in today's economic environment, with the added advantage of me being able to build and service it (although the Ameritron is very simple inside, easy to service and I don't have to build it, for two hundred dollars more!).

Re: [Elecraft] Voice Announcement
Toby et al, Like Gary Lee, I'm a blind ham and have been using the K3 quite successfully for the past two years. As stated by others, Elecraft has promised improved access to the K3 for such things an the config menus. After some initial sighted help to set a few of the menu settings, I've managed to utilize most of the features including the NB NR CW and voice memories, all split functions and diversity RX. I operate 99% CW on the low bands chasing DX. Also, the FW upgrades are a breeze with the K3 utility. Previously, I've owned many other rigs with menus that were much more difficult to use with out sighted assistance. Some of those include: FT-1K-MP, MP Field, IC-756 Pro and by far the most difficult and questional performance was the FT-2000. In summary, I'm delighted with the K3, its performance is outstanding, the support from Elecraft is great and I'm sure they will continue to improve the access for us blind hams. 73, Bob K3UL K3: 1572 and 3004 __ 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

Hi, That would be a real shame, Don, if you were to leave the reflector. Your postings have always been extremely helpful. Personally I am highly suspicious of anonymous postings on ham forums. As licensed hams there is no way for us to hide as we have it all hanging out on FCC's web site. Most of us are posting even more information on QRZ.com and personal web sites. Why don't you simply ignore the anonymous postings and continue to be of assistance to everybody else?

Re: [Elecraft] k2 pll and ref osc issues n0xdb
This is Elecraft's forum and they have the ultimate switch on these things. Having said that, just to straighten up an injustice here Name and call sign is not personal information, it is a matter of public record There is no expectation of anonymity on this reflector. This IS a HAM reflector, and name/callsign in the usual places is appreciated, and usually done without any thought. Those who don't add name and callsign simply stand out by the omission. It does not take much research in the archives to see that a lot of anonymous posts are trolls, which is why it grinds on so many. There ARE what amount to technical arguments here, but the players all have names and callsigns, and after a while perhaps there are familiar takes on a given individual. People are who they are. Nothing to hide. Someone called Don (W3FPR) rude. Shows what they know. There is not a rude bone in Don's body, and even if there were, he probably has the all-time record for nearly perfect technical assistance and no one on the reflector (including the Elecraft principals added together) has his online time helping reflectorees. Beyond that he has an almost insane patience with individuals in situations that to me scream RTFM. If you somehow HAVE managed to get Don riled, you ARE over the line. He should not have to defend himself.

[Elecraft] RTTY using DATA mode on K3
Hi Everyone, I just bought a K3 a few weeks ago and have been using it on CW. It's time to play with it a bit on RTTY. I'm using the Tigetronics Signalink to interface the radio to my PC which is running MMTTY. When I have the mode switch in the sideband position, copy on the laptop is just fine and the signals display properly on the tuning aids in MMTTY. I read the manual pages about better performance if the DATA mode is selected. I switched to the DATA mode and there is very little audio in the speaker and no signals displayed on the tuning aids in MMTTY. No copy either. I double-checked the data mode setting and it is AFSK-A which I think is correct. I must have a setting wrong somewhere. I've gone over the data section in the manual a few more times but don't see what I'm doing wrong. Any ideas?

Re: [Elecraft] Voice Announcement
To all: At the present time, there is a pc program, k3voice, which gives limited access to the k3 display and settings. Elecraft plans to add access to all practical menu options in the future. As for operating a k3 while blind, I have been doing so for two years. The switchtone option is extremely helpful. While I have not yet figured out some things like psk and rtty decoding, noise reduction settings, and agc settings, the rig works well, and I only expect it to get better. Wayne and Eric have publicly promised access to all their rigs in the past, and I am confident they will come through. Where is KenYaecom with their million dollar engineering staffs with full access? I've only seen two, and rigs, and no promises, both rigs from kenwood. Yes Tobey, you are spot on that older rigs without menus are much easier to operate. However these are becoming like hen's teeth. I recently found an icom 751A with voice synth and external keypad. I, of course, snapped it up.

Re: [Elecraft] News from Visalia!
I agree, yes please, a remote-able, weatherproofed 500W tuner (capable of 160-6m) would create an instant order here too. I have relied on SGC tuners for many years, mobile, marine mobile and now at my small suburban plot where I have a custom DX engineering 50+ foot vertical with 40 radials. The beauty of SGC tuners is they only require a 12v source. In every situation these tuners have performed flawlessly in harsh environments for years. I was planning on getting a 500W Tokyo Hi Power amp at Dayton this year, but seeing the Elecraft amp, I will wait. The problem is that no one makes a 160-6M remote weather proof tuner capable of 500-600 watts which only needs 12v. SGC's 500 watt tuner doesn't do 160M according to their specs.

[Elecraft] KAT3 kit documentation
Just finished installing the antenna tuner kit (KAT3) in my K3 #888. The hardware disassembly and re-assembly instructions are, as usual, crystal-clear, and that went off without a hitch. However, when it came to actually bringing the KAT3 up and getting it running, the supplied instructions just say "refer to the K3 Manual." The problem with that is, the K3 Manual assumes that the antenna tuner unit is either installed and running, or not installed -- and while most of the data needed for bringing up the newly added KAT3 is all in there if you hunt for it, it is in several different places throughout the book. And completely missing was the little tidbit that you have to power down the K3 and then power it back up to get the new KAT3 configuration settings to "take" -- to recognize that the KAT3 is now in there and enabled. Prior to doing this, I just kept getting this "NO ATU" message. (Not too hard -- only took me about 20 minutes to figure out to try recycling power. High "duh factor" there. LOL) I think the configuration and start-up procedures should be added to the KAT3 kit instructions, so everything is all in one place, part of the overall documentation set for the add-on tuner kit.

Creating an application using the available software - simple GUI, readable by the reading software, assessable by function/cursor keys - and abstracting the K3 to their ability could be a 'solution'.

Re: [Elecraft] Re: News from Visalia! (:-))
A number I heard was $2000., but I have to admit, I don't recall who said it. I didn't ask about K2 interfacing, but since it's got the serial port interface, I suspect it'll work fine. Apparently it can follow the transceiver by either reading the serial port or by watching the drive frequency (frequency counter). Note that all of this is preliminary, and anything can change to some degree. Oh, and it's got front panel band buttons, one for each band, and using them changes the band on the K3, also. So now, band buttons for your K3. And it's possible that Elecraft won't actually produce a tuner themselves, but will make interfacing informattion available for others to do something that will work cleanly. 73, doug Date: Sun, 18 Apr 2010 09:08:58 +0800 (HKT) From: Johnny Siu Hello Doug, Any idea about the likely pricing.

Re: [Elecraft] KPA500 active devices!!
Well said tom, an often overlooked aspect is the angle of the mismatch, load pull is the only way to tell, while a 3:1 resitive is not to harsh, very few things will survive a 3:1 at an inductive reactance angle. Load pull is the only way to be sure, and I would be uncomfortable making any claims until such a test has been done.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
Joseph, Since you have a good frequency reading at TP3, the PLL Reference Oscillator is working, and the problem is in the area of Q18. So we move the problem area on the schematic to the upper right corner of the RF Board schematic sheet 1. Note that the VFO output goes through U3 before it gets to TP1, so try reading the VFO frequency at U3 pin 3. If you have a good reading there (reading should be 4915 kHz higher than the frequency displayed on the K2 dial for all bands below 15 meters). Since it worked once, the most likely problem is soldering, so re-flow the connections with a hot (750 deg F) iron. There is a possibility that Q17 was damaged by static during construction and failed later. As a test, short Q17 drain to its source and see if the VFO starts oscillating (you can accomplish the same thing by temporarily shorting lead #3 of T5 to ground). Count the turns on T5 carefully and look critically at the soldering of the T5 leads. If there is a visible ring around the lead, it was not well tinned - it has been said that solder connections should look like mountains, but *not* volcanoes, and that is an apt description of the condition I am referring to. The same thing applies to all solder connections, not just toroid leads. The solder should flow out on both the solder pad and the component lead to an almost invisible edge. If the solder looks more like a ball than a nice smooth fillet, it is likely that the connection did not receive enough heat. If there is too much solder, use solder wick to remove some of it. With thru-plated holes on the boards, the amount of solder required is only enough to fill the hole, although I like to see a very small fillet too. Neither the board or the component will be damaged with normal soldering temperatures maintained for up to 5 or 10 seconds, although you should use an iron temperature that produces a good solder connection in 2 to 3 seconds. If it takes longer than that, the iron is too cold, and if the solder flows in less than 2 seconds, the iron is too hot. Watch for the solder to *flow*, not merely to melt. 73, Don W3FPR Foxjazz wrote: > Hello Don, > > Don, the call was in the subject line. > > Sorry for the confusion.

Re: [Elecraft] K2 Encoder problems continue.
Hi Geoff. It is a real puzzler. I have checked the voltages on the encoder and these switch between 4.95V and 100mV when the shaft is rotated slowly, they don't alternate between each other but are in sync. It is possible to change the frequency using the encoder but only by a small amount and only if the shaft is spun quickly. Resistance readings between the 5V supply pin and the Enc A/B are infinate or beyond the range of my Fluke 77 meter in one polarity and 3.9MOhm in the other. Between Enc A/B it is 8,2MOhm and Infinate when changing polarity. Between 5V pin and Enc-enable it is between 4.2MOhm and infinate when changing polarity Enc A and Enc-enable between 8.15MOhm and infinate when changing polarity. Enc B and Enc- enable between 8MOhm and infinity when changing polarity. All measurements done with the encoder in cct. I have a friend just round the corner from me who is in the process of building a K2 (has been for quite a whlie :-) ) so we have arranged to do some testing this afternoon with his control and display boards. He also has a suitable scope so hopefully I will be able to test the function of the MCU also. I also have a Dataman S4 programmer so the possibility of reflashing the firmware may exist, though this may be a last resort as I wouldn't want to corrupt his radio as well. Again thanks to all on the reflector who have responed. Will update later today once the comparison tests have been conducted.

Re: [Elecraft] KPA500 active devices!!
< The VRF2933 is rated "3:1 Load VSWR Capability at Specifi ed Operating Conditions" according to its datasheet; perhaps that's why there no built-in ATU.> .but that doesn't mean SSB IMD would be acceptable, or it would be safe in every circuit at that mismatch, so keep that in mind. :-) No matter what the data sheets say about device life, the PA often needs to be kept within 1.5:1 or better SWR to meet IMD specs. 3:1 is a huge loadline move, depending on the direction of the impedance move it could really put the PA into severe flattopping. Use a tuner or fix the antenna, be safe. 73 Tom On Sat, Apr 17, 2010 at 6:44 PM, Doug Faunt N6TQS +1-510-655-8604 wrote: > There are two VRF2933's in push-pull, so they're not 750 > watts each, > but per pair.

Re: [Elecraft] K2 Encoder problems continue.
Nidge, Thanks for your reply. Unfortunately I do not know enough about Hamradio Deluxe nor its interface with the K2, but rightly or wrongly I assume that if the radio works properly under computer control, then the MCU (U6) is working as it should during this mode of control. I cannot shake my hunch that something is pulling down to near ground either the ENC A or the ENC B lines (or both) when the MCU is in place. If the encoder is an optical type, then under such a fault condition I would not be too surprised if the voltage on ENC RD also dropped to near ground - which is what you have measured at U3 pin 14. It would be worthwhile to make some resistance measurements between these three lines and ground, with the power off - MCU in place and MCU removed. Not to be overlooked is the possibility that the fault might be mechanical. For instance if a small sliver of solder had worked its way into the MCU's socket, it might create a short when the MCU chip is in place - but "open" when the chip is removed. Good luck. 73, Geoff GM4ESD On Saturday, April 17, 2010, at 11:13 PM, Nidge (Nigel Smith) wrote: > Hi Don and Geoff > > Thanks for the replies both. > > First of all Geoff: I'm afraid I don't have a scope here anymore.
