[Elecraft] K3--complete audio loss when rig is turned on
I am experiencing total audio loss--both through headphones and the speaker, and across all modes and bands--shortly after I first power up my K3. If I power cycle the K3, audio returns but then often vanishes again shortly thereafter. After "enough" power cycles, the audio will remain so I can use the rig without issue. I can tune with the VFO knob and change modes, so the radio is not totally locking up. On occasion--but increasingly less so--I will see an E[rror] numeric message on the display and a reference to the DSE. However, most times the audio just vanishes while the display continues to show the frequency. After the rig has been on for "a while," the issue goes away until the next time I go through a "cold start," so it may be something temp/time related. In researching this list, I've seen the references to reloading the firmware. I have tried that once to no avail. I have the following firmware versions loaded: MCU 04.39 FPF 01.14 DSP1 02.73 DSP2 02.73 K3 utility 1.4.4.25 I also am using a P3 loaded with firmware version 01.09. Does anyone have ideas on what could be causing this or what else I could check/test/tryto resolve this issue? Many thanks for any insights. 73 Paula k9ir -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-complete-audio-loss-when-rig-is-turned-on-tp7020261p7020261.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 alignment
Phil, If the K2 has been properly aligned before (R30 voltages, bandpass filter tuning, L34 tuning, SSB carrier balance and AGC settings), those things should still be in good alignment unless something in those areas was repaired in the meantime. K2s that I have worked on hold those settings even after several years. I do find that many K2s have never been properly aligned, so make your decision on your confidence level for the prior alignment. So I would suggest that you just do the C22 setting, CAL PLL and CAL FIL to get the dial calibration on target. For what I believe is the easiest way to do that, go to my website www.w3fpr.com and look at my K2 Dial Calibration article. The use of Spectrogram or other audio spectrum analyzer to verify the proper tuning of WWV is highly recommended. 73, Don W3FPR On 11/22/2011 12:26 AM, Phillip Shepard wrote: > I have a seven year old K2 that has not been aligned since the initial > testing.

[Elecraft] Problem after KPA100UPKT upgrade

Re: [Elecraft] Diversity mode preamp
So, what the K3 really needs then is a contest oriented application on a computer. Maybe something rich like PowerSDR but works with the K3 in a manner where contesting features (logging and contest log management) along with sophisticated macro control from a visual controls perspective. Indeed, now that I think about it, this would be a great application if it were designed to be configurable per each contester. Arrangements of controls on the screen, sophisticated macro control via custom U/I, and other nifty features. Thus, instead of sitting in front of the K3 with its small format presentation and the overload commands on the buttons, the computer would be much more useful if all K3 functions were available. Of course, it should be written on a Mac, or maybe an iPad. 73, phil, K7PEH On Nov 22, 2011, at 7:38 AM, Tom W8JI wrote: >> Maybe I am missing something but won't >> work? >> This should have no side effects at all.

Re: [Elecraft] Diversity mode preamp
There are very few things important during a contest that N1MM does not already do, and the ones that it does not do would be very clumsy on a screen even if the K3 allowed it. And I own an iPad, but I cannot think of a less efficient interface for doing a serious contest.

Re: [Elecraft] Problem after KPA100UPKT upgrade
Sam, I suggest you download the current manual for the KPA100 and begin with the diode voltage chart, then if necessary proceed to the DC voltage chart. It is difficult to say what is going on without some reference information. When making the measurements, be certain to observe the >10 watts and the < 10 watts columns. For a visual check, be certain you put the toroid leads in the correct holes. Is there any chance you put the resistor on the bottom of the board in the wrong place - that would cause the problem you are having. 73, Don W3FPR On 11/22/2011 9:17 AM, scramac wrote: > I just upgrade my K2/100 with the KPA100UPKT upgrade last night but somehow > I'm not getting any power out>10watts.

What would be almost as good is being able to program buttons for dedicated single functions. Like I use M1-M4 for bandwidth changes. It is much better than the rotary knob to just poke a preset button. There are many things that never get used, but I am not aware of any way to program them to a different use. Like I never use the ATU, because I don't have one. I never use the ANT, only have one port. Never use the NB or NR, because with a crowded band it just kills RX performance.

A good system always balances the signal levels in. Always. I can't imagine ever having antenna choices that have not been relatively equalized in noise floor. The problem is sometimes there is a need to increase or reduce gain on both RX channels immediately, in just fractions of a second time. Say a strong station comes on for a while, or we change directions and a modest signal becomes strong and starts to overload, or one direction has 20 dB more noise. Another case is the noise floor has crept up, and the op was too busy to notice and now suddenly does but is busy. __ 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] AC Pole Interference
For 36 years, I worked as a "pole engineer" for a large municipal electric utility. When I was new at the job, my boss got a call from a concerned citizen. He was told that a young feller (that was 1969) driving a city car was banging on poles with an ax and drilling holes near the ground. My boss said "good"! Meant that I wasn't down at the Tug Tavern getting rehydrated! We were taught to "sound' the poles and listen for for the pole to "ring". Rot in the upper sections of the pole doesn't support vibrations and has a dead sound. And we drilled into the "rot zone" just below the ground line with 18 inch "bell hanger bits". This is definitely "a hard hat zone", but I never had anything other than old bird dropping dust and wood flakes "rain" down on me! I learned to step back and not look up after delivering a good blow with the back side of my ax. A lot of cyclic noise from poles actually comes from defective street lights. They make noise when they start up, and some lights cycle off and on every few minutes. This can be quite strong for several blocks. In the "old days", we had two technicians with a well equipped van to locate radio noise. Their jobs got eliminated in budget cuts. Complaints were handled on a "hit and miss" basis after that by employees with little training and equipment. 73, Rick Dettinger K7MW > > I agree. There's also the matter of HOW you whack the pole.

Re: [Elecraft] US 60 Meter Band Changes Approved by FCC
Another recent post by Don Wilhem as to commercial use of only USB is correct and has always "been" to my recollection. A bit of a history lesson is in order here. The use of LSB on 75 meters and USB on 20 meters (there was NO 40 meter voice band at the time!) in all probability is a phenomenon started by a "phasing" exciter known as the "SSB Jr." and it's derivatives, the most famous one being the Central Electronics Model 10A, then the model 10B and 20A which were possibly the most popular "factory made" transmitters at the time. All these exciters had no USB and LSB markings on the mode switch, but they were designated "SB1" and SB2". The reason this was done was due to the conversion process employed as the SSB signal was generated at 9 Mhz and heterodyned to either 14, or 4 Mhz with a 5 MHz VFO signal. Whichever position of the mode switch was used (SB1 in all probability, it's been too many years for me to precisely recall and not really important at this time for me to research it!) At any rate, the result was Upper sideband signals on 14 Mhz and lower sideband signals at 3.8-4.0 Mhz. Why switch the switch when changing bands to maintain the "same" sideband? Laziness prevailed! "Convention started" (LSB on 75, USB on 20) continued on 10 and later 15 meters by the use of USB and when voice was permitted on 40 meters, LSB there. The "tradition" has continued thru the present day. Commercial SSB has ALWAYS been upper, used extensively for Shipboard and aeronautical HF communication ever since. Some "Fixed" HF communications have made use of "ISB" in which the lower and upper sidebands carried simultaneously independent information on the two sidebands. In this case "lower" is utilized. It is rather difficult to get a radio receiver built for commercial use that is actually fitted with a "Lower sideband" filter unit! Many very fine receivers used in the maritime service are almost, if not impossible to actually find a "filter module" for to enable "LSB" use! Government users almost ALWAYS utilize Upper Sideband, hence the use of it on 60 meters where the Amateur Service is a "secondary user" of the spectrum space. Hope this clears up the WHYS of upper on high bands and lower on lower bands and why it started. My information is what I recall years ago, so don't hold me responsible for small errors or minute details about the why's and when's! 73, Sandy W5TVW -Original Message- From: Kevin Cozens Sent: Tuesday, November 22, 2011 10:54 AM To: K2 Subject: Re: [Elecraft] US 60 Meter Band Changes Approved by FCC On 11-11-19 02:36 PM, Mike Morrow wrote: > Yesterday (18 November 2011), the FCC published its approval of changes > to the US 60 meter band.

This might lead to a solution, Knut. The first question is, are there commands in firmware to do what Tom needs? I'm pretty N1MM will send a command string on the serial port (including a USB converted serial), and the operation could be assigned to almost anything on the keyboard with a Hotkey program like the one that K1TTT and N2IC recommend. Is it called AutoHotKey? An example that I KNOW is possible is triggering the DVR memories from F-Keys. The macros to do this are long and a PITA to type into N1MM, but they work fine. Tom -- perhaps ask about this on the N1MM list, or ping N2IC and K1TTT directly. 73, Jim K9YC __ 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] Contesting use
I would spring for a big front panel only (with some mounting attachments) that remotes the K3 over a piece of CAT5. Unplug the CAT5, it goes normal. Function of buttons configurable. Add a "null" front to replace the regular front panel of the K3 together with a back plane for the normal front panel to interface the normal front panel to the rest of a K3. This would allow a seamless use of the smaller or larger "remote" front panel. Add an internet front for the radio and an internet back for the front panel , and run the radio from anywhere over a LAN or the internet. Publish the interfacing and let the world write K3 front panel programs for K3's with "null" front panels. This would be in keeping with Elecraft's modular, only buy it if you want it, approach.

Re: [Elecraft] AC Pole Interference
Poor connection in hot line clamps used for taps off a main line or for equipment connections, etc. are notorious for causing RF noise as well as creating fires and shock hazards in situations like Tom mentions. Hot line clamps are used where it is not cost effective to install disconnect switches. The older hot line clamps did not have spring loading, and in time, with wind vibration, the clamps had a tendency to loosen. Three things have been done to mitigate this problem of burning a tensioned conductor in two. 1. Hot line clamps now have spring loading. 2. Hot line clamps typically have a dab of oxide inhibitor in the mouth of the clamp as it comes from the factory. 3. Most utilities crimp install a "Saddle" loop on the conductor, and then connect the hot line clamp to the saddle. Then, if the hot line clamp connection fails it only burns the saddle loop, and not the tensioned conductor.

With great respect, macros are not the answer to every usability problem. Macros are enormously powerful, but they are not a substitute for cleaning up the rough edges that still remain in the K3's firmware. Macros need to be used sparingly because the K3 only has two completely uncommitted programmable keys (PF1 and PF2). Any additional macros will either block some of the normal functions of the Memory/DVR keys or else they must be executed from outside the K3. Each of those workarounds will create problems for a segment of users. And then there's the SPLIT button. The one button that above all others *should* be reassignable to a macro, is not! The K3's SPLIT button simply engages split mode and does nothing more. Every other high-end transceiver has the option to protect the user from accidentally transmitting on the same frequency as VFOA - and most DXers will want to take that option. But in the K3, this 'smart split' option requires a macro which must then be assigned to some *other* programmable key. The existing SPLIT button then becomes a booby-trap for the tired owner; or even worse, it risks a very unpleasant introduction to the K3 for someone else. I'm sorry if this reads like a rant, but someone just said "Macros?" one time too many. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek __ 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] LSB on 75 Meters (was: US 60 Meter Band Changes...)
Whatever the genesis of the LSB/USB convention on the ham bands, this conversion scheme wasn't it. Mixing a 9 MHz USB signal with a 5 MHz VFO will produce a USB output on either 4 MHz or 14 Mhz. The sidebands only get inverted in a mixer when you subtract the SSB signal from a higher frequency LO. This "ham legend" has persisted literally for generations despite frequent debunking. Maybe we can eradicate it by teaching our grandkids that "We had to use LSB back then because DSP hadn't been invented yet."

If you have a 5.0 - 5.5 MHz VFO and subtract a 9 MHz USB signal from that VFO you end up with a LSB output that tunes from 4.0 - 3.5 MHz in reverse. Start at 5.0 and subtract the 9 MHz carrier frequency you get *minus* 4.0 MHz (carrier frequency) when the highest modulating frequency (3 KHz or 9.003 MHz) is used you end up with *minus* 3.987 MHz - *lower sideband*! Do the same with the VFO at 5.5 MHz and you will find LSB at *minus* 3.497 to 3.500 MHz. A mixer can produce F2 +/- F1 just as easily as it produces outputs at F1 +/- F2. If you don't believe this ... spend some time reviewing the early SSB transmitter and receiver articles in QST from the 1950s or borrow a Drake 1A/2A/2B and learn why some bands "tune backward." 73, ...

Re: [Elecraft] LSB on 75 Meters
First, let's dispense with the red herring of backward tuning. The VFO does tune backward on 75 but it has nothing to do with sideband inversion. The USB/LSB business works the same way with a fixed LO as with a VFO, and it works as I described. When you mix a 5 MHz signal with a 9 MHz signal, there's no need to stand on your head and pretend that you're subtracting 9 from 5 to get minus 4. Instead, you go back to second grade and subtract 5 from 9 and get 4. Working the sideband part into it with a 9 MHz USB signal and a 5 MHz LO - Suppressed carrier freq: 9.000 minus 5.000 = 4.000 3 kHz modulation tone: 9.003 minus 5.000 = 4.003 Just as a sanity check, take another look at your own negative number example, Joe, and 'splain to me how 5.000 minus 9.003 gives minus 3.987. OK, I'll grant you a typo and assume you meant minus 3.997, but you're still wrong. It's minus 4.003.

Re: [Elecraft] Diversity mode preamp
Ok, I know this is a dumb question but I hope someone can help me or point me in the right direction. With my K3 and also my IC746PRO before that they both have the Noise Reduction function. Whenever I use it, all I hear is a watery version of what I hear without it. Are my ears just that bad or am I doing or listening wrong. I know this can be a long answer so if someone wants to go off reflector that would be fine. The explanation in the book means nothing to me. I guess I just don't get it.

[Elecraft] FS: K2/EC2 with KAT100-2 and KPA100/KAT100-1
I have great K2 with the following options for sale: KSB2; K160RX; K60XV;KNB2; KDSP2; KAT2; FDIMP;KIO2; and KBT2-X without battery. The K2 is in excellent alignment and plays as well as IC7800 according to Sherwood tests. I also have the matching EC2 enclosure with the KPA100 and KAT100-2 which matches beautifully with the K2. Both units have the latest firmware and include 60 meter coverage and the Transverter Option. I want $1200.00 for the K2 and $500.00 for the EC2 with KPA100 and KAT100-2. I will take $1500.00 for both with shipping. I will throw in an extra KAT100-1 antenna tuner with the K2 and the EC2 with the KPA100 and KAT100-2. If I sell items separately I will sell the KAT100-1 for $150.00. I would prefer to sell the package along with the cables and power cord. Again this unit is about as good as it gets with all updates, modes and latest firmware. 73, W0SZ __ 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] Answering Questions Effectively
I have been waiting for a slow reflector day to post this very low priority message (Perhaps that day will never come!, so here goes...) but various threads keep touching on the point that I have been wanting to make, and a current K3 thread has yet again exhibited this behavior. Let's say that you're having trouble with a particular rig control/logging program. Let's say for example that it doesn't properly put the transceiver into transmit under certain conditions. If I made a suggestion such as, "The K3 already has a XMIT button that you can use to put the rig into transmit," you would probably be irritated with me because, of course, that isn't what you desire to do. You want the computer to perform that function, not a front panel button. Yet, again and again, when someone poses a particular problem or question about the operation of an Elecraft product often one or more of the responses is, "Computer program ABC can do that." Well, that may be true, but it doesn't help the original poster. The original poster probably isn't interested in finding a computer solution; he's interested in finding a solution within the rig itself. Perhaps one possible reason for this is that folks who use a computer with their rig 100% of the time assume that everybody does (or should). It is not my intent to debate this particular issue, only to point out that it's not realistic to assume this. In my opinion, we should be more sensitive to whether or not a computer solution is the right solution, and always help the poster dig down to find a real solution to his problem.

Re: [Elecraft] Answering Questions Effectively
A "slow reflector day," particularly on this list does not exist in our universe. Good point, Al. I've watched Don, W3FPR, for quite awhile. Someone posts a problem. The post might be missing some information ... OK, usually is, see my own "problem posts" for good examples. 15 responders post "solutions." Don, however, asks questions. Pretty simple engineering: "First understand that there is a problem and what it is; Then find solutions."

Re: [Elecraft] Contesting use
My vote is for a K3 accessory similar to the TenTec "pod" - an auxiliary tuning knob mounted on the pod along with several pushbutton switches (8 to 12) that can be programmed to send macros to the K3. The pod sits on the desk, so the tuning knob and buttons are horizontal - less tiring for the operator than a vertical panel. I believe that could be a great solution to the contesting station. In reality, there are not a great number of buttons that are needed after setting up the K3 for a contest. It would be easy to relate the function of a dozen buttons (each of which do one and only one thing) to a guest operator. 73, Don W3FPR On 11/22/2011 12:01 PM, Tom W8JI wrote: > Operators need buttons or toggle switches that serve one function.

Re: [Elecraft] Contesting use
Absolutely agree! In fact I have mentioned it several times in the past. That is the one thing I miss from my switch to the K3. If they could pretty much duplicate the Ten-Tec pod I would be a happy camper. In fact, with the macro capabilities of the K3 it would be even more useful than it is on a TT rig.

Re: [Elecraft] K3 RX ANT OUT
RX ANT OUT is connected to the TX antenna 1) when not transmitting, and 2) when RX ANT is selected. That is all. The function is there to allow patching in a preamp or filter for receive. The relay that does the switching has the RX out connected to a contact rather than a pole. Sorry. 73, Guy.

Re: [Elecraft] Contesting use
I too would like to see an external Pod similar to the one that TenTec has would be the right idea. Contesters can beat the pod up, triggering CW/Voice memories and frequently used functions which saves a lot of wear and tear on the main unit as well as making things more comfortable/efficient. 72/73 & DX, Craig W.

That's a real PITA for users, and completely un-necessary when it is SO easy to simply update the Programmer's Reference as changes are made. You can do a lot of editing in an hour, then 5 minutes to pdf it, another five minutes to upload it to the website. I do this all the time with stuff I'm writing myself. 73, Jim K9YC __ 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] SW TONE change volume ?
Is there a way to adjust the volume of the switch feedback tone on the K3 ? I like the high freq / low freq tone pair you get when a switch function is turned or off but it is too loud, I would like to adjust the volume lower if possible. I found the menu item for disabling the tone but not volume adjustment.

Re: [Elecraft] Contesting use
This sort of item is just the "pod" I was referring to. I do not know of the specifics of this particular pod, but it holds promise.

Re: [Elecraft] Contesting use
There is a lot than can be done with macros -almost anything that can be done with the K3 buttons. Define what functions need to be accomplished by a particular pod button press and the K3 will follow. If there is software intervention, that is not significant - the required operation must be properly defined to the guest operator - it should have nothing to do wit the K3 menu settings or the K3 button pushing - it should produce the expected results when activated - nothing more and nothing less. Set it up before a contest and communicate "which buton does what" to the guest operators and all should be well. 73, Don W3FPR On 11/22/2011 10:23 PM, Bill W4ZV wrote: > This looks very promising for 12 macro keys and a VFO: > > http://xkeys.com/xkeys/xk12JSH.php > > Has anyone done this with the K3? > > 73, Bill > > > > David Gilbert wrote >> You may want to check the X-Keys website like W4TV suggested.
