From n7tb at comcast.net Sun Jan 1 00:06:04 2017 From: n7tb at comcast.net (Terry) Date: Sat, 31 Dec 2016 22:06:04 -0700 (MST) Subject: [Elecraft] All the Amplifier Discussions Message-ID: <1483247164726-7625301.post@n2.nabble.com> As I have been reading the various threads on Amplifiers over the past few days, I am struck by the incredible variety of topics and activities that bring all of us joy in Amateur Radio. For some of us, it is the ability to make contacts with very little power. For others, just running a standard 100 watts and trying to earn DXCC etc. or other awards, is a great challenge. For others, getting every bit of legal power output as possible, or discussing what 1-3 dbs. means in making that contact is very important whereas, someone else might say, "Who cares?" We all get enjoyment from the hobby in so many ways. The maximum power I have ever used was 100 watts. With a good yagi, there was never a station if I heard it, I could not work it. I might have not been able to bury everyone with a kilowatt signal and be heard first, but it is really an amazing thing to be in the fray with the big boys and through timing of the call and other tricks learned over the years, get someone to come back to me. I was exclusively an SSB operator for 24 years, then took 9 years off from the hobby then came back as a CW operator. It was quite a challenge to get my speed back after so many years of viewing CW as a means to get up to Extra, instead of a mode of conversation that I could really enjoy. After all these years, What I have discovered is not whether I can squeeze out all the power possible, or have the greatest antennas, or all the greatest rigs, (Although my K2, KX3, PX3, and KXPA100 are absolutely the best rigs I have ever owned....thanks Elecraft!) or spent time on this group arguing the minute details of some technical question, even though many get a great deal of enjoyment doing that. What I have discovered is it is the relationships we make on the air with our fellow hams. It is that human connection across the miles, whether it be several miles on 160, or around the world on 10, it is the great memories of all the interesting hams I have met on the air, both on SSB, Digital, or CW that really make Amateur Radio special. We are all very fortunate to have such a great hobby to enjoy...and to always remember it is a hobby, and that family always comes first, yet have great experiences along the way. When I became a ham at 34 years old, I thought about how ham radio would be with me throughout my life and as I got older and had more time, it would be wonderful to have the hobby. Now that I am 68 years old, I still don't seem to have enough time, but ham radio is a wonderful hobby to enjoy. One of my realizations is that even though I have enjoyed several sunspot cycle maximums over the years, if I am lucky, I will get to enjoy only one more in my lifetime. Life passes so quickly. Enjoying every day in the wonderful hobby is such a blessing, and I know that many of us share those thoughts.

Not in the case of Yaesu and Icom (at least). Both use ALC circuits with excess gain which activate after the PA is driven into saturation. The excess gain also drives the IF and driver stages into saturation. Since the "roofing filter" (on rigs like the FT-1000 or IC-756 series) is a relatively broad VHF filter, that distortion, clipping and splatter is not limited to the audio bandwidth and easily extends to 25 KHz or more. 73, ...

I have fldigi 3.22 displaying DATA mode during normal operation, using Rigcat and K3.XML as the rig control template. Are you saying you can't see a mode change after accessing the drop-down (next to the main frequency readout)? You should be able to see mode and filter, and you should be able to change them. 73, matt W6NIA On 1/1/2017 7:02 AM, George Kidder wrote: > Hi gang, > I am running fldigi with my K3, and everything works as indicated in > the manual.

The current K3.xml file relays changes between the rig and the two little blue boxes under the frequency display, but these changes are not reflected in the fldigi operate mode, nor do changes in the op mode result in changes in the K3.

So I now need to find a different way to work with Rotating Macros. The nicest way would be for Elecraft to add more Macro space to the K3, but I'm not sure if and when that may happen. So this leaves me looking at other methods since It's easy to hold down a button on the K-Pod and mess up the rotating macro. Can the K-Pod be set to not use one bank of Macros (1-8)? Can the P3 Macros be setup as rotating Macros?

In addition to the capacitive coupling of the switch itself, note that only the center conductor is carried between inputs and outputs, so that the chassis carries return current. This adds a lot of inductance to the path, and causes crosstalk between circuits. The RIGHT way to do this is to provide a coaxial path, so that return current is confined to the coax shields. If you look inside the Alpha Delta switches you see that they are built that way. There's not coax cable between in and outs, but the physical construction is such that the body of the switch forms the return path. Not perfect, but FAR better. 73, Jim K9YC On Sun,1/1/2017 10:37 AM, John wrote: > What Dale describes below is a very similar configuration to the MFJ switch > I was given a year or so ago - an MFJ-1703. > > I just popped the lid off and took a photo of the insides for you: > > https://www.dropbox.com/s/h28jny6vrkj7rdj/2017-01-01%2018.28.00.jpg?dl=0 > > The only difference being that it's basically a DPDT slide switch, rather > than a rotary.

John (XLX) -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: 01 January 2017 19:32 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] {OT} - Variation on use of a coaxial switch (stan levandowski) The isolation provided by this switch will be really poor. In addition to the capacitive coupling of the switch itself, note that only the center conductor is carried between inputs and outputs, so that the chassis carries return current. This adds a lot of inductance to the path, and causes crosstalk between circuits. The RIGHT way to do this is to provide a coaxial path, so that return current is confined to the coax shields. If you look inside the Alpha Delta switches you see that they are built that way. There's not coax cable between in and outs, but the physical construction is such that the body of the switch forms the return path. Not perfect, but FAR better. 73, Jim K9YC On Sun,1/1/2017 10:37 AM, John wrote: > What Dale describes below is a very similar configuration to the MFJ > switch I was given a year or so ago - an MFJ-1703. > > I just popped the lid off and took a photo of the insides for you: > > https://www.dropbox.com/s/h28jny6vrkj7rdj/2017-01-01%2018.28.00.jpg?dl > =0 > > The only difference being that it's basically a DPDT slide switch, > rather than a rotary.

I feed it at one corner with 450 ohm twin lead connected to a 4:1 voltage balun, then coax to my rig. I can tune all the ham bands either barefoot to my K2 or KX3 and the KXPA100 using their internal tuners. My new QTH will not have the real estate to do what I can now. I was hoping someone who is well versed with the EZNec antenna program could give me an idea of how well what I think I can build, will work. I will have a yagi for 10-15-20. I am particularly concerned that I may not be able to tune 80. I have a Sunday CW qso with a group of great guys on 80 and want to keep participating. Here is the info on the new horizontal loop: The east side will be 54 ft. long and be 2 ft. above my roof at a 35 ft. height. That leg of the loop will be over a roof that slopes away for about 8 feet. The west side will be 78 ft. long and up 20 ft. The remaining north and south sides will be 38-40 feet each of the same length. This will give a loop a bit longer than 200 ft. I plan to feed it again on a corner, the NE corner when it is two feet from the roof and I can run the twin lead down the side of the house to my shack. I know this will be predominantly a cloud burner, but that is fine on 40 and 80. My concern is being able to tune it on the 80, 40, 30, 17, and 24 meter ham bands. My lot is only 80 by 100 so a doublet on 80 will not work without folding it in several locations. I have loved my loop and would love to be able to continue using one. The fact that it is horizontally polarized is so nice for being able to work weak stations without a lot of noise. If anyone could help me with the analysis of this antenna, I would appreciate it. 73's, Terry, N7TB From w0fm at swbell.net Sun Jan 1 17:26:52 2017 From: w0fm at swbell.net (Terry Schieler) Date: Sun, 1 Jan 2017 16:26:52 -0600 Subject: [Elecraft] {OT} - On Professional Error In-Reply-To: <81B2153F-109F-496D-B961-F6D4D2F69D67@mac.com> References: <38F7A997-808C-4F3B-99C4-EA454ED3A90F@law.du.edu> <81B2153F-109F-496D-B961-F6D4D2F69D67@mac.com> Message-ID: <004901d2647e$271c2ae0$755480a0$@swbell.net> And, we musicians refer to our mistakes as "improvisation".

I use my KX2/KXPA100 most of the time and that's the position the switch will be routinely be in. The other switch position will be connected to 50' of un-terminated coax. Every once in awhile I feel like operating my little KX1 a) while lying in bed, b) by a roaring fire in my fireplace while it's snowing, c) on my front porch on a summer night with a glass of iced tea and d) on the back deck while doing BBQ. The switch and the 50' of coax allow me to connect my KX1 to my SGC-231 and (amazingly!) there's enough RF to kick the coupler into action.

Bias to the microphone is applied through a resistor, not directly from a voltage source. All you need to do is turn BIAS on in the MIC SEL menu. See the K3 manual for the button to tap to toggle the bias setting. 73, Don W3FPR On 1/1/2017 7:09 PM, Ron Manfredi wrote: > Thanks, Don.

My rule of thumb, which has worked for many quickie antennas is to use insulated #14 wire and close-wind on a 2" white PVC pipe a length of wire that is twice the length of that removed from the antenna. You will loose some bandwidth, but you will be on the air. Comment about the proposed loop: If the overall physical size is a little short - you are using tuned feed, so it will not make for that big a loss. It also does not have to be square - five or six sides will do fine - just get as much open space inside the loop as possible. Proximity to the roof means proximity to the RFI from the house. Nothing scientific or big worded here - just things that work that are based on my experience over the years.

If you do not wish to bury 32 radials for a ground screen, consider using resonant elevated radials. Two elevated radials running in opposing directions will do the job nicely. Put the elevated radials above ground by about 10 feet to keep them out of the range of humans and deer and other things running into them and causing harm. If there are horse riders who will be riding through your property, you may want to increase the height to 15 feet. 73, Don W3FPR On 1/1/2017 4:55 PM, Terry Brown wrote: > I am moving from my current QTH where I have a horizontal loop up about > 35-40 ft. that is a bit longer than 1 wavelength on 80.

To avoid confusion about how antennas work, it's best to call this a counterpoise, and leave the word "ground" out of it. The first function of a counterpoise is to provide a path for return current. The earth is a terrible path, because it's basically a big resistor, so it burns a lot of transmitter power, leaving less for the antenna to radiate. Radials are a nearly ideal form of counterpoise, because they not only provide a low resistance source for return current, but they also shield the antenna from lossy earth. In addition to the very good solution that Don described, there are other possibilities. K2AV has designed what he calls a "folded" counterpoise that fits on a pretty small lot. Google to find details. His original design was for 160m, but it can be scaled for 80M. I've given several talks to ham clubs about "getting on 160 from a small lot." It's mostly about antennas and counterpoise systems. http://k9yc.com/160MPacificon.pdf For 80M, divide the dimensions by 2. 73, Jim K9YC From k3ndm at comcast.net Sun Jan 1 22:23:19 2017 From: k3ndm at comcast.net (Barry) Date: Mon, 02 Jan 2017 03:23:19 +0000 Subject: [Elecraft] Need help from an EZNec user on a horizontal loop question In-Reply-To: <6590afb7-f1ff-1324-600a-4d13bdfa035b@embarqmail.com> References: <002501d26479$d6775190$8365f4b0$@comcast.net> <6590afb7-f1ff-1324-600a-4d13bdfa035b@embarqmail.com> Message-ID: Don, Good suggestion. Let me suggest a variant that at least two of use are using. I use it because of my severe space limitation. Basically, the antenna is an inverted L that is fed at its center at the top of the vertical run thereby obviating the need for a ground. It has a total length of a about 1/2 wave, but half is vertical, or nearly so, and the rest runs to a convenient tree that is a little lower than the tree holding up the vertical piece. I feed it using 450 Ohm ladder line to a 4:1 current balun where I transition to coax. I ran an Eznec simulation of this antenna. It appears to play really nicely on 80-30 meters, and the lobes get a little crazy starting at about 20 meters. On the air, performance appears to agree. The downside of this antenna is the vertical piece is susceptible to local man-made noise. This is far from a perfect antenna, but I sure can work DX and locals. Let me restate that this is not a perfect antenna. I started down this road as the upper bands are not going to be great as we slip lower in the solar cycle and I wanted to get DXCC on 80 and 40. This antenna does lay down a low lobe on both bands and losses are reasonable. A good horizontal antenna will have a higher radiation angle at the support heights I have. This is my way of dealing with the problem of getting low angles with reasonably high supports. If I had 100+ foot supports around, I might look at some other option. 73 & Happy New Year, Barry K3NDM ------ Original Message ------ From: "Don Wilhelm" To: "Terry Brown" ; elecraft at mailman.qth.net Sent: 1/1/2017 9:44:06 PM Subject: Re: [Elecraft] Need help from an EZNec user on a horizontal loop question >Terry, > >Have you considered an 80 meter inverted L? > >It takes up little real estate for the radiator, but does require >putting down a ground screen at the base of the inverted L. >If you do not wish to bury 32 radials for a ground screen, consider >using resonant elevated radials.

That length puts the voltage "loop" (maximum) at the rig, so the counterpoise requirements are minimal on 80. The L is 40 feet vertical and 80 feed horizontal. That puts the current max near the bend on the "flat top" for high efficiency. I have my own Homebrew L-Net tuner on a shelf above the rig that will handle the huge voltages experienced at exactly 1/2 wave, but by finagling the length the impedance can be brought into range of the K3s/KAT500 tuners without a huge loss in efficiency. However note that the antenna terminates right in the shack so you need to be concerned about meeting safe RF exposure limits, especially if running more than 100 watts on the higher bands. I use mine with good results on 160 through 20 meters. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Sunday, January 1, 2017 6:44 PM To: Terry Brown; elecraft at mailman.qth.net Subject: Re: [Elecraft] Need help from an EZNec user on a horizontal loop question Terry, Have you considered an 80 meter inverted L?

My IT guys have been moving my web site over to a new server so I can have an SSL compliant web page. The old host was not facilitating the transfer but this week we have been able to get limited help from their tech support due to the holidays. Looks like we are now making some progress on the change and we should be back up and running shortly. I appreciate all the support and business from you over the last 3 years. We are here to stay and I will have some new products in January as well! I will post again here when we get the web page back on line. 73 Scott AK6Q._,_.___ ________________________________ Posted by: kd6qzx at sbcglobal.net ________________________________ Reply via web post ?

Message-ID: <1C3C43D1-7F32-4CC5-8CD2-1B564DEF3732@icloud.com> Hi all, First wishing everyone a prosperous 2017. About 18 months ago I reported a problem to Elecraft. The problem is that whilst the internal batteries in my KX3 are charging overnight and at the same time the alarm has been set to turn the radio on the next morning then the radio will never turn on. If batteries are not being charged then the alarm function works fine. This problem was verified by Elecraft (Got an email stating this) but no solution has been forthcoming since. I hope Elecraft reads this and provides a solution so that these function(s) can be operated simultaneously. Other then that, very happy with my KX3 being almost 3 years old.

It is a four terminal coax relay called a "Transfer Switch" that for example, connects any two antennas to any two radios, but never at the same time. In other words, radio A connects to antenna 1, and at the same time, radio B connects to antenna 2. Activating the switch ( either mechanical or electrically activated) changes the condition for A to 2 and B to 1. Most are good for a kilowatt well up into the UHF ranges. For HF, I made one using a heavy DPDT relay. 73 Charlie k3ICH -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Richard Fjeld Sent: Monday, January 02, 2017 1:13 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] {OT} - Variation on use of a coaxial switch (stan levandowski) Years ago, I built such a switch to prevent accidents should one radio transmit when comparing two radios.

I am still not understanding why I can transmit CW in SSB mode with the key line without leaving SSB, but not with a KPOD macro. But since none of the Elecraft folks have responded to this twice asked question, maybe that?s the way it is. I can hook up a keyer to the CW key line and send all the CW in SSB mode I want. I was just trying to use a KPOD button push for convenience.

I've been calling those "sequencing" macros. Say Macro 8 sets AGC THR to 5 and Macro 7 sets AGC THR to 15 and holding PF2 is assigned to Macro 8 and you would like to use successive holds of PF2 to toggle between THR 5 and 15. Code is added to the end of each macro to reassign PF2 to activate the other macro. (I don't remember who came up with this but it a nice idea although a bit like the old self modifying code days.) You can't do this directly with a KPod button because their macro assignments cannot be reassigned like programmable function keys. But you can do it indirectly by making another macro, say Macro 16, hold the PF2 key. Now tapping KPod button 8 holds PF2 which toggles THR. Note that (at present) the first two macros have to be in 1-8 because function keys can only be assigned to those locations. So instead of two macros and a function key you use three macros, a function key, and a KPod button.

I fixed that and PA ON operation of the KXPA100 is now working. The bad news, however, is that in Basic operation with PA OFF, the KX3/KXPA100 puts out full power, but the most I can get out of it with PA ON is 50-60 watts. The attenuator is set for OUT/AUTO and there is no more than 1 or 2 watts reflected power.

I wouldn't want to use that kind of power with the switch I made. I didn't know about the switches you mention. I thought there should be a need for them, so I called MFJ. I like to protect my equipment. I know guys who don't think this way. Maybe MFJ didn't sell any and discontinued them.

Yes, it is expected. There is low-drop diode in series with incoming power to protect the radio circuitry from reversed polarity at the power connector. The typical voltage drop is about 0.3V at nominal current. The internal "12V" supply voltage being reported is after the diode's voltage drop. Both radios share this characteristic. 73, Lyle KK7P On 1/2/17 10:46 AM, E T wrote: > When using the special VFO B display to show the supply voltage, both my KX3 and KX2 disagree with the rest of my equipment.

I am curious to know if anyone on the reflector has experienced this issue. I occasionally like to use my KX2 at QRO power. I have the ACC output of the KX2 interfaced to a KPA500 which is interconnected to a KAT500 antenna tuner. When the tuner is not powered, the KX2 and amplifier work perfectly with over 150W output. When I power up the KAT500 and switch the amp to ?oper? mode, the receiver in the KX2 desenses rendering the combination inoperable. When switching back to ?STBY?, the receiver is back to operating normally. Turning off the power to the tuner allows normal operation. Not sure what is happening. Any suggestions? Tnx.

That is the actual operating voltage of the transceiver. The Shottky diode typically drops about 0.3 volts, so the internal measurement will be about 0.3 volts lower than a voltage measurement external to the transceiver. 73, Don W3FPR On 1/2/2017 12:46 PM, E T wrote: > When using the special VFO B display to show the supply voltage, both my KX3 and KX2 disagree with the rest of my equipment.

I have a KX3 and a KXPA100 and with the recent thread about running a calibration I figured I needed to do likewise. The amp is a new addition to my setup so I am still learning the details. Anyway, while running the KX3 Utility I get a failure during the calibration process (the output is below). The amp is in bypass mode and I am using an MFJ-260C for the dummy load attached to ANT1. Is the failure only on 29.000Mhz or does the whole process fail if any of the calibrations fail? Anyway to continue? Also, could the temperature of the dummy load impact the test, that is if I run the test back to back several times, as the dummy load heats up will this impact the process (I am thinking yes)? Should I cool the dummy load before testing? Thank you in advance.

There is low-drop diode in series with incoming power to protect the radio circuitry from reversed polarity at the power connector. The typical voltage drop is about 0.3V at nominal current. The internal "12V" supply voltage being reported is after the diode's voltage drop. Both radios share this characteristic. 73, Lyle KK7P On 1/2/17 10:46 AM, E T wrote: > When using the special VFO B display to show the supply voltage, both my KX3 and KX2 disagree with the rest of my equipment.

You can check your dummy load at 28 or 50 MHz with an antenna analyzer. You apparently did not disconnect the KXPA100 when running the KX3 TX Gain Cal procedure. Remove the KXPA100 and run with the KX3 and the dummy load only. If you do the manual procedure in the KX3 manual, it should be good for all bands where it passed. If you used KX3 Utility, it quits on the first band that produces an error. After you get a successful TX Gain Calibration with the KX3 only, then do the TX Gain Cal for the KXPA100 as indicated in Appendix B of the KXPA100 manual. Your dummy load must be rated for 75 watts or greater. 73, Don W3FPR On 1/2/2017 1:52 PM, Aaron Marroquin wrote: > I have been a lurker on the reflector for almost a year and this is my > first email to request guidance. > > I have a KX3 and a KXPA100 and with the recent thread about running a > calibration I figured I needed to do likewise.

You can have K3 commands stored in a P3 macro, though. So to do what you would like, you need to store the macro one of the 50 P3 macro locations and then assign it to one of the P3 function keys. The reason it works from the Utility is that the serial communication path to the K3 is through the P3 and so the P3 acts on its commands. (And just to be a bit pedantic, I think it is better to not call K3 macros Kpod macros. The Kpod doesn't store any macros. It just provides an additional 16 function keys that activate the 16 macro storage locations in the K3.)

In DATA mode, there's an audio drop-off between 200 and 325 Hz, with an almost completely dead audio "hole" between 250 and 300 Hz. Then there's some additional noise between 350 and 500 Hz. If I switch to USB mode (with no EQ or audio effects applied, naturally), all of these artifacts go away, and it's perfectly smooth across the spectrum. No drop-off, no noise.

Did not find any Birds, used or otherwise, and the Transcos I found were in the $800 range. I confess this was a very quick search. Interesting that many if not most of them require 28 VDC. Anyone know why? Is that a marine application? These seem too heavy for aviation. The subject is of interest because I have two MFJ SPDT switches, neither of which I particularly like. One of them works fine if the switch knob is toggled back and forth a few times. And that?s the one that?s been indoors all its life. Anyone found something DPDT, store-bought and acceptable, in a moderate price range?

I intended my switch for receive comparisons. I am surprised the commercial switches can handle a kilowatt and provide adequate isolation. I wouldn't want to use that kind of power with the switch I made. I didn't know about the switches you mention. I thought there should be a need for them, so I called MFJ. I like to protect my equipment. I know guys who don't think this way. Maybe MFJ didn't sell any and discontinued them. At the time, I thought they described them rather vaguely, missing the whole purpose. Maybe I haven't found them on their website now.

Of course when I use my PowerWerx supply I can set that to anything? :-) But do not turn on the PowerWerx while the KX3 is running or you'll receive a nasty surprise. There's a strong voltage spike from the PowerWerx that overwhelms the KX3 and the KX3, in response, shuts down. If you plan to use the SLA as backup while mains power fails, be sure to turn off the PowerWerx before mains power returns. 73, Marc W8SDG From nick at n6ol.us Mon Jan 2 18:54:29 2017 From: nick at n6ol.us (Nicklas Johnson) Date: Mon, 2 Jan 2017 15:54:29 -0800 Subject: [Elecraft] Audio artifacts in DATA A mode with KX3 In-Reply-To: References: Message-ID: J?rg in the Elecraft KX3 group on Facebook had an interesting observation: with WJST's waterfall, if the "flatten" mode is on, it produces some unusual artifacts in the presence of sharp spectrum drop-offs, and indeed if I turn off the "flatten" feature and manually set the zero point for the waterfall, the artifacts go away.

I run Windows 7 under VMware Fusion on a Macbook Pro. Although it's a difficult environment to maintain, most Windows software works well. I run RemoteRig boxes to connect a local K3 acting as a control head to a remote K3. The RemoteRig box presents the remote K3's serial port as a local port (COM12 today) and both Writelog and N1MM+ can connect to it and control the remote radio. Right now, however, K3 Utility and K3 Memory Editor are not connecting to it. (Yes, I terminated the loggers before trying the Elecraft apps.) I'm pretty sure this configuration used to work, so I'm baffled. Usually it's the other way around - a COM port has changed and I use K3 Utility to discover which new port number to specify in the logger. But today the logger connects and Utility doesn't. If I eliminate the RemoteRig boxes and associated K3 Remote firmware, both K3 Utility and the logger connect to the local K3 just fine from the virtual Windows OS. I'm running FW Rev 5.55 on both K3's. Any ideas?

Sorry. What are the functional disadvantages that make it apparently undesirable to build an antenna switch that is a crossover 2 radios x 2 antennas? What if you only used one path at a time but could switch them easily? Crosstalk? Is it so strong as to damage the other radio? Is it not possible to achieve acceptable compatibility with 2 radios and 2 antennas? Or to swap amplifiers between two radios and two antennas by placing one on the input and another on the output of the amplifiers? Or to swap in the better antenna for a short contact that you just can't seem to make on the current one? I don't relish placing a switch on each antenna and another switch on every radio in order to connect anything to anything. How do you do it? It would take 4 1x2 switches on the input of the amplifiers and 4 more on the output to do what could be done with 2 switches of 2x2.

The real question is just how much RF energy will leak back into the non-transmit transceiver. Yes, there is the possibility of damage to the receiving circuits and T/R switch of the receive transceive that is just supposed to be listening if it gets too much RF at its receive input. That is what the real discussion is all about. The amount of isolation required in the switch depends on the power level. If you are talking about 100 watts power from the transmitter, 40 dB isolation is likely OK, but at higher powers, you will need more isolation. 73, Don W3FPR On 1/2/2017 9:53 PM, Jim Miller wrote: > Off topic.

I have a mechanical A/B switch DIAWA Model CS-201. Fairly inexpensive. Internally, it has a cavity design to provide isolation between the ports. Using an HP signal generator and an HP-3586C selective level meter the isolation of the switch was measured. The used port was terminated in a 50 ohm dummy load. The "open" port went into the selective level meter which had a input Z of 50 ohms. The HP-3586C can measure RF power levels accurately within a few tenths of a dBm. Differences are at least as accurate. Here are some numbers: 160M/80M 80 dB isolation 20M 69 dB isolation 10M 60 dB isolation 6M (by extrapolation) 46 dB. YMMV Note the frequency dependence. This switch provides the 40 dB isolation necessary. I have no connection with DIAWA but was interested in this topic. I suspect there is some real junk out there. Obtaining 60+ dB isolation isn't easy. The slide switch "designs" described by some are likely in that junk category. If in doubt measure. You have two rigs and an S meter. Input .1 or 1 watt to the switch terminated as above and look at the S meter for the rig on the open port. Scale the results to 100 W. If it shows S9+80 dB or less, you are likely OK. Keep in mind many S meters are horribly inaccurate. They tend to be too generous at around S9. Not knowing could be expensive. 73 de Brian/K3KO P.S. In the past, I did the same measurements with coax relays. My recollection: Obtaining 40 dB isolation at 10M was not possible with some of them. Their internal design was not as good from an isolation standpoint. Lower power coax relays provided better isolation (smaller contact size?) than high power relays. So be careful with coax relays.

Turn to the back of the K2 manual and do the Transmit Signal Tracing procedures. While doing the procedures, work in the order listed. You may ignore RF voltages that are greater than the listed expected value. What you are looking for is the first point where the RF voltage is substantially lower than the expected value. That is the output of the failing stage. Check that stage in detail - component values, solder connections, DC voltages etc. Refer to the schematic to identify the components associated with that stage. 73, Don W3FPR On 1/3/2017 8:46 AM, Byron Allen wrote: > Serial # 4455 > > What would cause the following low power after all the bandpass filters > have been peaked? maximum power setting > From rsoifer1 at aol.com Tue Jan 3 10:02:47 2017 From: rsoifer1 at aol.com (rsoifer1 at aol.com) Date: Tue, 3 Jan 2017 10:02:47 -0500 Subject: [Elecraft] KXPA100 with PX3 In-Reply-To: <207ddf7e-b50b-90e6-b0ef-2674b70334a4@embarqmail.com> Message-ID: <15964daa449-7c34-55ed3@webprd-m58.mail.aol.com> Don and all, The KXPA100 is working fine now, well within specs.

The K3UTIL jumps between 4800, 9600, 19200, and 38400 baud trying to establish a connection. I suspect this could be resolved for non-conventional serial connections (virtual serial ports, remote connections... ) if K3UTIL.EXE could employ an optional command line argument to disable baudrate bingo and force a fixed baud rate .

I run Windows 7 under VMware Fusion on a Macbook Pro. Although it's a difficult environment to maintain, most Windows software works well. I run RemoteRig boxes to connect a local K3 acting as a control head to a remote K3. The RemoteRig box presents the remote K3's serial port as a local port (COM12 today) and both Writelog and N1MM+ can connect to it and control the remote radio. Right now, however, K3 Utility and K3 Memory Editor are not connecting to it. (Yes, I terminated the loggers before trying the Elecraft apps.) I'm pretty sure this configuration used to work, so I'm baffled. Usually it's the other way around - a COM port has changed and I use K3 Utility to discover which new port number to specify in the logger. But today the logger connects and Utility doesn't. If I eliminate the RemoteRig boxes and associated K3 Remote firmware, both K3 Utility and the logger connect to the local K3 just fine from the virtual Windows OS. I'm running FW Rev 5.55 on both K3's. Any ideas?

You were right again; the system was way out of calibration. All told, there were two problems: the calibration and the RJ-45 connectors in the control cable. I also replaced the 22A switching power supply with a big old 35A linear supply that just loafs at the 14.5A current drain from the KXPA100.

You might have accidentally installed a malicious "extension" for Chrome. I had a situation last year with an extension that was not flagged by Google as malicious in spite of many 1 star reviews and was also not flagged as malware by anti-virus and anti-malware programs. It was designed to set the referral cookie for eBay and Amazon to benefit some specific party. It was called something like "eBay helper". I'm hoping that Google starts identifying scam extensions like that as malware, but it's possible one has been installed on your machine. Check to see which Chrome "extensions" you might have installed. To do this, navigate to this URL: chrome://extensions/ I recommend uninstalling any that you are not certain of the origin of. 73, Matt NQ6N On Tue, Jan 3, 2017 at 4:00 PM, Richard Fjeld wrote: > I agree.

SWH40; Toggles the text decode function. Use the VFOB knob to choose the speed range, threshold setting or OFF. I assume you want to control Text Decode remotely with a KPOD since it gains you nothing to assign that to one of the K3 front panel switches instead of pressing the K3 TXT DEC switch. You can assign that macro to any of the first 16 locations in the K3 so you can launch it from the KPOD. Use the KPOD rocker switch to enable control of the VFO B function at the KPOD to choose the speed range, threshold setting or OFF. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Tuesday, January 3, 2017 6:03 PM To: Mike Weir; elecraft at mailman.qth.net Subject: Re: [Elecraft] Macro for text decode Mike, A macro that will operate the CWT button would be in order - nothing complicated at all. 73, Don W3FPR On 1/3/2017 7:26 PM, Mike Weir wrote: > I checked the archives looking for information regarding a macro for the K3 that will turn the text decode on and off.

Narrowing the bandwidth is one that comes to mind so the decoder does not have to deal with band noise and other nearby signals. There are other controls that can enhance the decoding. In other words, it may produce better results by careful tuning and other manual controls instead of trying to depend on a a "one button" macro initiation to provide clear CW decode. Besides, the human ear is the best interpreter of CW - it will be better than any CW decoder implemented in software. A CW decoder can usually interpret perfect code, but it will have trouble with code sent from a bug with a "lake Erie swing" or code sent from a hand key unless the sending operator has perfect timing (rare). Listen to CW so your brain can interpret it without relying on CW decoders, and you will go a long way toward increasing your CW speed. 20 wpm is the initial goal you should strive for. 73, Don W3FPR On 1/3/2017 10:03 PM, Harry Yingst via Elecraft wrote: > > I also have been trying to get this to work for the CW mode and have not gotten it to work reliably From tomb18 at videotron.ca Wed Jan 4 00:07:06 2017 From: tomb18 at videotron.ca (Tom) Date: Wed, 4 Jan 2017 00:07:06 -0500 Subject: [Elecraft] Macro for text decode In-Reply-To: References: <863257584.5751293.1483498983958@mail.yahoo.com> Message-ID: I stand corrected. At some point early last year, the K3 firmware was updated to use the UPB; and DNB; which will allow changing of the text decode in CW. Prior to that, the UPB; and DNB; commands did nothing when the SWH40; command was issued and therefore made it impossible to set text decode on or off without using the remote control K3/0 protocol. So the way to put the radio into text decode is as follows: SWH40; UPB;UPB;UPB:UPB; and then you issue as many DNB; as you wish to choose the setting. You can do it the other way around as well. SWH40;DNB;DNB;DNB;DNB; and then UPB; for TX Only, another UPB; for CW5-30 and then UPB; for CW 30-90. The multiple UPB; s are used to put the setting into a known state since there are 5 states to the menu item and you could be anywhere in the sequence. It is good that the UPB; and DNB; commands don't cycle though the list continuously. There are a couple of commands like that which then require reading the VFOB display to determine where you are. It should work fine now if timing isn't an issue. 73 Tom va2fsq.com -----Original Message----- From: Don Wilhelm Sent: Tuesday, January 3, 2017 11:23 PM To: Harry Yingst ; Mike Weir ; elecraft at mailman.qth.net Subject: Re: [Elecraft] Macro for text decode Harry, Turning CWT is no more complicated than operating the CWT button, but there are other things that may be involved to achieve successful decode.

Power should be measured with an external meter. It doesn't have to be very accurate, just repeatable. If the currents are about the same, I'd suspect the SWR bridge in #1. If not, things get more interesting.

At some point early last year, the K3 firmware was updated to use the UPB; and DNB; which will allow changing of the text decode in CW. Prior to that, the UPB; and DNB; commands did nothing when the SWH40; command was issued and therefore made it impossible to set text decode on or off without using the remote control K3/0 protocol. So the way to put the radio into text decode is as follows: SWH40; UPB;UPB;UPB:UPB; and then you issue as many DNB; as you wish to choose the setting. You can do it the other way around as well. SWH40;DNB;DNB;DNB;DNB; and then UPB; for TX Only, another UPB; for CW5-30 and then UPB; for CW 30-90. The multiple UPB; s are used to put the setting into a known state since there are 5 states to the menu item and you could be anywhere in the sequence. It is good that the UPB; and DNB; commands don't cycle though the list continuously. There are a couple of commands like that which then require reading the VFOB display to determine where you are.

Adjusting the same knob up and down as required, in my case setting it to zero makes the tone inaudible in both the speakers and the headphones.

If you plan to attend, Elecraft owner or not, I would like to hear from you. I hope both current owners and prospective owners participate. Let me know what you might like to see/hear. I will have use of a projector and can give my New Mexico TechFest presentation on Station Automation featuring the K-Line or the excellent "FIELD DAY GUIDE TO THE ELECRAFT K3 for SSB-FD" PowerPoint show. I'm also hoping Elecraft will provide promotional materials based on a message I sent them earlier this week. I will setup my K-Line with a portable antenna or two on Friday from 12:30 to 3:00 p.m. in Area 4 and operate the special event station W6V. Brian, K7RE, will be there two and we may operate his KX3/KXPA100/PX3 too. Please stop by and say hello. We would like to meet you! The entire list of presentations is not on-line yet at quartzfest.org/activities.html as I write this. Stay tuned; Tracy, WA6ERA, is working on a big lineup! Hopefully, we'll be able to park far enough away from the maddening crowd to attenuate the very noisy inverters and generators that permeate the QuartzFest crowd. 73, Bill, K8TE From g8kbvdave at googlemail.com Thu Jan 5 03:38:58 2017 From: g8kbvdave at googlemail.com (Dave B) Date: Thu, 5 Jan 2017 08:38:58 +0000 Subject: [Elecraft] Elecraft Website Hacked? In-Reply-To: References: Message-ID: You might want to use FireFox, or Chrome (Chromium) with the "Ublock Origin" add-on installed. (I believe it will some time soon be available for MS's Edge too, but as I've largely moved to Linux now, that doesn?t bother me.) You get the best of add blocking and malicious script prevention, while allowing intentionally visited web pages to function as they wanted you to see. In essence, the best of AddBlock+ and NoScript, but without the hassle. In the case a site "Needs" you to see adds (some "commercial media" sites etc) then you can allow such things on a case by case basis, without compromising yourself on other sites. If using FireFox, erase your browsing history and set it to not save any, & have it erase all cookies when it shuts down, never save passwords, and not use the master password facility (there are issues with that, should your master pw get "lost"...) Similar settings are available within Chrome(Chromium) of course. Then, each new browsing session, is just that, new... If you still experience unwanted redirects, check your systems "hosts" file for anything odd, also see if the same thing happens with a totally unrelated system on the same net connection. (Tablet or phone on WiFi.) If so, your ISP could be sending you places you don't want to go... No affiliation with any of the above mentioned "products", just a happy user of some... Happy New Year.

(Nothing like Windows, more like BSD!) You may need to add your regular login username, to a group for easy access to the serial ports. Under many Linux(s) sudo adduser #### dialout (Substitute your regular login user name for the ####) Will do the job. What the equivalent command would be on a MAC I don't know in detail. You may even first need to make yourself root to use that, as you need to on FreeBSD, that the MAC OS is more like than Linux. You should also be able to find out what any USB<>Serial adapter is known as, by using a command line tool such as dmesg, and examining the last few lines of that, just after connecting the device to the computer. In fact, run dmesg before, and after inserting the adapter, you'll then see the difference... ( dmesg | tail Should only show you the last 10 lines, not the entire stored archive!) Note too, that WSJT etc, uses Hamlib for radio control, that in turn uses whatever that needs to reach the radio(s.) So, if not already done as part of the WSJT install, you may also need to install that separately. 73. Dave G0WBX.

The strip came with a 12v switcher that I ignored. I use my 12 volt supply. The strip was, I think, 24 inches long and has a dimmer that can be inserted in the power lead. No RFI. Plenty bright.

Have you plugged the Signalink output into the Line-in jack on the K3? Make certain the plug is fully inserted. Then go into DATA A mode and set the MIC SEL menu to LINE. Adjust the MIC Gain (now LINE IN gain) to produce 4 bars solid with the 5th bar flashing on the ALC meter - You can do that is TX TEST mode so you do not transmit RF. If the MIC GAIN is 'touchy' and at a very low level, go to the computer and adjust the soundcard level lower. Normally a soundcard level of about 75% is workable - too low and the S/N ratio is bad and too high the soundcard can overload. 73, Don W3FPR On 1/5/2017 9:10 PM, KC6CNN wrote: > Has anyone used MRP40 with success with the K3 or with a K3 and signalink > usb? > I have tried and tried to get this to work. > It will key the signalink and will key the radio, but no output or audio is > transmitted. > Sending the audio to my speakers works, but not to the radio. > I have set jumper jp2 and jp3 to on which raises the output level of the > signalink. > I have adjusted the windows audio level and still nothing.

I also do not currently have a way of assessing the EMI situation with your setup. However, it is an amazingly versatile lamp and well worth the $13 price! Even if you select something else, you may want to have one of these around for other purposes. Some of the things I like about it: Very small and light and easily moved around for the task at hand. Convient recharge from any USB port. 3 selectable light intensities. Very long time between recharges. I use mine fairly intermittently, but get 2 or 3 months usage on a charge. For $13, it can be considered a throw-away item if you don?t end up liking it. 73 Craig AC0DS From k0az at centurytel.net Fri Jan 6 10:58:55 2017 From: k0az at centurytel.net (Mike Sanders) Date: Fri, 6 Jan 2017 09:58:55 -0600 Subject: [Elecraft] FS PR-6 preamp Message-ID: <000201d26835$c929c940$5b7d5bc0$@centurytel.net> I have an excellent PR-6 preamp with the double male BNCs as well as the DC cable and connectors and the DB15 to the K3 ACC for control of the preamp.

If you plan to attend, Elecraft owner or not, I would like to hear from you. I hope both current owners and prospective owners participate. Let me know what you might like to see/hear. I will have use of a projector and can give my New Mexico TechFest presentation on Station Automation featuring the K-Line or the excellent "FIELD DAY GUIDE TO THE ELECRAFT K3 for SSB-FD" PowerPoint show. I'm also hoping Elecraft will provide promotional materials based on a message I sent them earlier this week. I will setup my K-Line with a portable antenna or two on Friday from 12:30 to 3:00 p.m. in Area 4 and operate the special event station W6V. Brian, K7RE, will be there two and we may operate his KX3/KXPA100/PX3 too. Please stop by and say hello. We would like to meet you! The entire list of presentations is not on-line yet at quartzfest.org/activities.html as I write this. Stay tuned; Tracy, WA6ERA, is working on a big lineup! Hopefully, we'll be able to park far enough away from the maddening crowd to attenuate the very noisy inverters and generators that permeate the QuartzFest crowd. 73, Bill, K8TE From alorona at sbcglobal.net Fri Jan 6 13:40:09 2017 From: alorona at sbcglobal.net (Al Lorona) Date: Fri, 6 Jan 2017 18:40:09 +0000 (UTC) Subject: [Elecraft] K3S Set-up for WSJT-X In-Reply-To: <6da12336-a900-d200-bdb2-dfdb73d6cc86@googlemail.com> References: <6da12336-a900-d200-bdb2-dfdb73d6cc86@googlemail.com> Message-ID: <1919294516.1883644.1483728009208@mail.yahoo.com> Wow, things have changed.

Starting from around 2V output (say) the LED/s will be OFF. As you increase the regulator's output voltage, somewhere around 2.5V (depends on the exact type of LED you're using), the LED will begin to conduct forward current and start to emit light. At this point, increasing the regulator's output voltage just a tiny bit will increase the brightness of the LED a lot (it's basically an exponential curve). So at just a couple hundred mV above the voltage where the LED began to emit light, you will reach full brightness. Any further increase in the drive voltage will merely result in the series current-limiting resistor dissipating more heat. What is really needed here is a linearly-variable constant-current generator circuit. This is a fairly simple circuit to design, usually consisting of a voltage reference, a comparator, and a drive transistor, with some feedback from a current sensing resistor. It will need to be designed so that it can generate enough voltage to overcome the LED's forward voltage (Vf), and with an output current that's variable from 0mA to around 20mA (or whatever the LED's maximum forward current (If max) is specified at). Hope this helps.

The only way you avoid it is if they use a simple series dropper resistor, which is not energy efficient. LEDs are constant current devices, so there is no such thing as a 12V LED (an LED with a 12V forward voltage drop would be well into the far ultraviolet, and would still need current regulation). Professional installations would use a switching constant current supply (typically called a driver). Those for amateurs and the average building contractor would mimic tungsten bulbs by having a constant current switching regulator in each bulb. Some cheap mains operated lamps use capacitive droppers followed by rectifier and resistive current limiter. They are the type likely to be sold in one dollar stores, or on Ebay. # On 06/01/17 11:50, Marc Veeneman wrote: > \ > >> On Jan 6, 2017, at 2:00 AM, Peter D.

Controlling the (linear) current to an LED is an easy way to vary the brightness, but the useable range is limited. You can test this with a typical voltage & current regulated bench supply. Set the output voltage at say 3 to 4 volts with the current limit set at 1 to 2 mA. The long lead of the LED is positive. Then adjust the current up to the rating of the particular LED you're testing. 50 mA is fairly high, so 20 mA might be a safe max amount, but you will see a definite variation in light output. Typically, component, or panel type LEDs are monochrome. That is, they emit a very narrow frequency band of light. A lamp designed for home use must however, emit a much wider band such that it's illumination quality covers about the same range as an incandescent filament light bulb. The quality of this light as well as the central band of energy is defined as a temperature in degrees* Kelvin. A "warm" light will typically emit light in the 2500 to 2700 K range, where-as the higher temperatures around 6500K are much "bluer", or more like daylight. The actual light is emitted NOT by the LED itself, but a phosphor coating inside the LED which is excited by the LED's output. Dirt-cheap hand flashlights can approach a wider band of light by combining a yellow and a blue LED in the same package. I may be wrong, but I believe panel type "white light" LED's use a combination of color LED's much like a TV screen to generate the white light. One characteristic of an LED is that it shuts off instantly when the current through it is cut off. With a phosphor driven LED there will be a noticeable time lag as the light output fades out on power down. 73, Charlie k3ICH *A particularly fascinating scientific concept is that any substance, when heated to the same (incandescent) color will be the same temperature. It doesn't matter if it's charcoal, a wire filament, or a feather, if it glows the same color, they'll all be the same temperature. Degrees Kelvin is just a convenient way of defining that temperature, or color. The item will go from red through orange, to yellow as the temperature rises. This was the at one time, the lab standard for measuring high temperatures. A filament, placed in the path of a lens was heated via an external calibrated current source. When the visible wire seemed to disappear through the scope when it was the same color as the observed item, the temperature was read off the current dial. Obviously, this was limited to the temperature range where the filament glowed.

Take a fictional regulator that has a fixed output voltage of 1V. Assuming you want 15mA through your LEDs, make sure the output current of the voltage regulator is 15mA by placing a 67 Ohm resistor from the output pin to ground. The current out the VOUT of a 3 pin regulator will be equal to the current at the VIN of the regulator. Then put your string of LEDs from the "unregulated" voltage in and the Vin pin of your regulator. You will have to add up the expected voltage drops of the LEDs. and subtract that value from the unregulated Voltage supply. then subtract the voltage regulators output voltage, in this case 1V from whats left. Now, make sure that the remaining voltage is at least a little bit higher than the dropout voltage of the regulator. I have done this countless times. It should be pretty simple to use a POT and a resistor to dim the LEDs within a preset range, or if your regulator has a shutdown pin you could PWM it from your favorite microcontroller. You should avoid putting LEDs in series when using a simple dropping resistor. That scheme will seem to work well for a little while then you may find your LEDs failing. In my experience this doesn't work long term and in this scheme the LEDs fail one by one shorted. I don't think the voltage drop on each LED is all that constant over time and temperature. 73 KD8CIV On Sat, 2017-01-07 at 02:14 -0800, Dave Fifield wrote: > An LED is basically a fancy diode, so a linear voltage regulator to control > its brightness will not work well. > > Starting from around 2V output (say) the LED/s will be OFF.

Over time the forward voltage drop of an LED will decrease somewhat as it ages. It isn't great, and it isn't fast, though it happens more quickly initially. The forward voltage drop decreases more dramatically in the short term with temperature - the higher the die temperature, the lower the forward voltage drop. This can result in thermal runaway and destruction of the LED when using a constant voltage supply and not a constant current supply. This can be mitigated with a current limiting resistor in series, but it does decrease overall efficiency of the system.

I was fixated on the power supply issue without considering the nature of the load. I like Walt's suggestion of simply switching in more LEDs as needed. A rotary switch adding more LEDs with each position would make adjusting the light level easy with a simple turn of the knob. It may be "brute force" as Walt says, but sometimes the simplest is also the most elegant and efficient solution. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Walter Underwood Sent: Saturday, January 7, 2017 8:08 AM To: Elecraft Reflector Subject: Re: [Elecraft] Dimmable LED desk lamp for operating position recommendation needed A brute force solution would be to get four LED lighting strips that run off 12V and use four switches.

The single line of dots is interpreted with the upper graticule in RX, and with the two lower graticules on TX. For what you want, there would need to be two rows of dots driven independently. Or there would need to be a front panel button to switch the meaning of the single row of dots. Ah, but we already have the button. Also, the change would require *both* firmware *and* changing out the display to create the **two** lines of dots on the display. Note that the graticules do not change. The display is not driven pixels like a smartphone display. Therefore it could not just be a new CONFIG: option in firmware. The request would almost certainly need to be implemented with a new transceiver. As it is, on voice if CMP and ALC is properly set, on a K3/K3S the power out is very predictable for a given PWR setting, more so for a K3/K3S than most. In any event, TX SSB with an amp, various stand-alone power meters deal more substantially with power out aspects. 73, Guy K2AV On Sat, Jan 7, 2017 at 10:52 AM, RichardG3ZIY wrote: > It occurred to me that on transmit the S meter is somewhat redundant.

The KX3 may sound slightly more natural, but overall I prefer the K3 because of better ergonomics and some aspects of performance. Recently I got interested in SO2R and added a KXPA100 to my KX3 for use as the second radio. In side by side comparison it became clear that the KX3 is much more vulnerable to interference than is the K3. With my antennas close together, the KX3 was marginally useable receiving on 40 while the K3 transmitted on higher bands, but totally unuseable with the K3 on 40 and the KX3 on a higher band. There are a lot of variables involved, but I got the same result with a portable setup at a different location. Most people will never run two rigs set up close together with antennas close together, but I plan to buy another K3 and sell the KXPA100. The KX3 is still wonderful for light weight portable operation. 73, Erik K7TV From ua9cdc at gmail.com Sat Jan 7 16:02:41 2017 From: ua9cdc at gmail.com (Igor Sokolov) Date: Sun, 8 Jan 2017 02:02:41 +0500 Subject: [Elecraft] kx3 receiver verses k3s receiver References: <6AC08742-A82C-43D6-9588-97902062569D@optonline.net> Message-ID: Vincent, I have both radios and often use them at the same time connected to Expert 1.3K-FA amp that supports basic SO2R operation. KX3 is a nice travel radio. Although it can be used for contesting when one operates far away from highly ham radio populated areas (EU, USA etc) still K3 is a lot better for contesting, especially when there are several strong nearby stations around. Besides K3 with the second receiver gives you great flexibility when used either for diversity reception of when picking signals from 2 directions using 2 antennas. Bottom line is you take both if you can or choose the one that you can afford. You will not regret in any case. 73, Igor UA9CDC ----- ???????? ????????? ----- ??: "Vincent Diak" ????: ??????????: 8 ?????? 2017 ?. 1:04 ????: [Elecraft] kx3 receiver verses k3s receiver > QST- Hello, > Can Anyone tell me if they have compared the KX3 Receiver to the K3s > receiver?

The K3 controls power very well, so if you have set the power knob to some particular power, that will be very close to the power you actually get. There is normally no need to monitor it - as long as other conditions are followed. The most common error for soundcard data modes is for hams who choose to follow the common internet advice to "set the power to maximum and control the power with the audio drive" - that does not work well with the K3, K3S, KX2 or KX3 (or the K2 for that matter). Drive the Elecraft ALC meter as indicated in the manual - 5 to 7 bars for SSB and 4 bars solid with the 5th bar flickering for soundcard data modes. Elecraft radios do not control power in the same way as other transceivers, so follow the instructions given for your Elecraft transceiver and first set the audio drive properly and control the power output with the power knob. Failure to do that will result in what I call "power hunting" where the power output will vary significantly. If I must elaborate on the "why" of all this, Elecraft radios control the power output in a closed loop - other amateur transceivers use an open loop "drive" control, commercial transceivers may use a closed loop system similar to Elecraft. The power output is measured and the MCU compares that output with the power requested by the power knob. If the actual power is less than requested, the drive will be increased to make the output equal to that requested. So if the audio drive is not sufficient, yes power will be lower than the requested value and the transceiver will go to full possible drive (and excess power will be produced when the audio output is increased). For those who are concerned about the ALC meter indication, the onset of ALC is at the 5th bar on the meter - the 4th bar is the "NO ALC" point for the K3 (KX3, KX2 and K3S). For the K2, increase the audio until you have ALC indicated, and then back off the audio just enough that no bars are displayed. The real key is to set the audio as instructed in the manual, and then control the power with the power knob. That goes for voice modes as well as soundcard data modes. 73, Don W3FPR On 1/7/2017 1:51 PM, Guy Olinger K2AV wrote: > Hi Richard, > > The issue with your request is that there is only **one** line of display > "dots" on the display.

Unfortunately as the Elecraft product line grew, the number of support persons has grown too - it now numbers 4 - David, Craig, Howard and Gary, and the Monday morning support email load is large. Problems that the support staff cannot handle are still passed along to the engineers, but that may be in the background while the support people handle the major communications back to the customer. Yes, I am close to the Elecraft team (particularly the support and sales folks), and do most of the repairs on the K2 and other "thru-hole" kits in the Elecraft line. So I am quite familiar with that part of their operation as well as their problems. Personal phone numbers are no longer given out (protections for the employees except in extreme cases), but you will still receive personalized customer support service via email or they will often phone customers with problems. I do serve as support for those "Thru-hole" products when Gary is not available, and I can say for myself that (from me) you will receive extended personal support when required - yes even help with a lifted solder pad. I am in North Carolina, and am in a different time zone than Elecraft, but that makes little difference, we still communicate with each other and the customers when the need arises. 73, Don W3FPR On 1/7/2017 5:36 PM, Jim Rogers wrote: > Does anyone remember the good old days, back when the K2 was king, you > would call support and would be routed to an engineer or perhaps in the > case of the DSP2, Lyle himself?

I just sold all my modern (big three makes) stuff and my shack now consists only of a K2/100 and a KAT100 and a K1 for when I feel like getting out of the shack. I tried all sorts of modern high end feature rich rigs with DSP/NR and all sorts of other variants and I felt it was just distorting what I was listening to. Please don't take that last comment as an excuse to drag out the pros and cons of each... I totally get that to some ears DSP is great and to others its not something enjoyable to listen to. Of the few little issues I've had with my K1 and K2 for things I wasn't able for figure out myself a quick email to support always returned a friendly reply with the help I needed, they genuinely do want to get you up and running when you have any issues. I think that's really good after sales service! On top of this, I like reading the emails on this group, mostly since they are K3 and computer related things they are not of great interest to me, but the ones that have a technical content (or K1/K2 realted) I find really interesting and I've either been reminded of something, or as in a lot of cases I've expanded my knowledge by reading the posts here. What I really like is that so many people chime into a subject and you get a broad range of solutions or views. Don't fall for the first answer that google happens to throw your way! Anyway, just felt like sharing my recent thoughts and experiences on the subject. 73, Cameron AF7DK ________________________________ From: Elecraft on behalf of lmarion Sent: Saturday, January 7, 2017 4:33 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Elecraft Support Maybe its just about the most fun I had as a QRP OP.

I like to run digital at 50 W max, to lessen the strain on the equipment. The advantage of this method was that the power on the band in use was not reduced, so that when going back to SW or SSB, the full power was still set. The "K3 recommended " method does a fine job, but requires reducing the power to 50 W. Then, when one returns to CW or SSB, you are still at 50W, since power is not saved "per mode". Would a software change which saves power "per mode" as well as "per band" be possible? If so, I respectfully request it.

This is mostly for running mobile with my KX3 than at the home shack that has a fine manual tuner (oldie but goodie). A silly reason is I will need an antenna switch for separate 6m and HF mobile antennas. But the tuner provides that plus remote control of the tuner/amp from the KX3 control panel. This becomes more than handy as finding a safe spot to pull off the road for manually changing bands and antennas is a safety issue. The KXPA100 will be in a compartment under the backseat which not simple to reach for power-on and swapping coax lines. New the KXAT100 is $379.95 plus shipping. I wonder if the tuner is ever available for sale as used by itself? My guess it would likely only be included when sold with a KXPA100. I will not make a purchase decision until this spring when we will be getting a 5th-wheel travel trailer. I already have the KXPA100 and the KXPACBL kit. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From k9yeq at live.com Sat Jan 7 20:45:44 2017 From: k9yeq at live.com (Bill Johnson) Date: Sun, 8 Jan 2017 01:45:44 +0000 Subject: [Elecraft] Elecraft Support In-Reply-To: <011c3fd5-7839-9c6d-c3d3-53e0a123ba0f@gmail.com> References: <011c3fd5-7839-9c6d-c3d3-53e0a123ba0f@gmail.com> Message-ID: I was an FT so not an issue to remember.

You are one of the kings of support and do so much for free, oftentimes without reward. I would hope that users would know that... thus my post. The amount of donated time to make the Elecraft products the best is amazing. I cannot even imagine how much time I have donated for the K2, KX1, KX3, KAT500 and other products offered by Elecraft. This is one of the main reasons for their success; we are dedicated to the hobby and asking nothing in return. Wayne and Eric and their team know this. Elecraft rules when it comes to product, quality and performance. There are users new to the product line that don't understand the lineage and find faults base on their limited knowledge an ability to compare products. Wayne and Eric know this and use the feedback for product improvement. And this is that! You and others are such a benefit to the product but so much more to the hobby. God bless you and the rest! (On that note, working on getting into KX2 portable on all sorts of antennas!!! KX3 sits in the living room and using CW for all modes not to disturb the wife. Just need a high powered amp to get back onto low bands in the pathetic sun cycle.) I love this hobby, but need more FT to really feel the love. 73, Bill K9YEQ -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Saturday, January 7, 2017 5:16 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Elecraft Support Jim and all, Yes, I remember those "good old days" when the only Elecraft support person was Gary (I was one of the K2 Field Testers). Unfortunately as the Elecraft product line grew, the number of support persons has grown too - it now numbers 4 - David, Craig, Howard and Gary, and the Monday morning support email load is large. Problems that the support staff cannot handle are still passed along to the engineers, but that may be in the background while the support people handle the major communications back to the customer. Yes, I am close to the Elecraft team (particularly the support and sales folks), and do most of the repairs on the K2 and other "thru-hole" kits in the Elecraft line. So I am quite familiar with that part of their operation as well as their problems. Personal phone numbers are no longer given out (protections for the employees except in extreme cases), but you will still receive personalized customer support service via email or they will often phone customers with problems. I do serve as support for those "Thru-hole" products when Gary is not available, and I can say for myself that (from me) you will receive extended personal support when required - yes even help with a lifted solder pad. I am in North Carolina, and am in a different time zone than Elecraft, but that makes little difference, we still communicate with each other and the customers when the need arises. 73, Don W3FPR On 1/7/2017 5:36 PM, Jim Rogers wrote: > Does anyone remember the good old days, back when the K2 was king, you > would call support and would be routed to an engineer or perhaps in > the case of the DSP2, Lyle himself?

Lots of snow, but it is 15 degrees warmer so I don't mind the slow driving. The sun has been sending solar wind our way even though it has been spotless for a few days. Charting the MUF over the last week has shone me why contacts are so tough on the higher bands (anything above 80 meters). I started using the Elecraft reflector in early 2001. The K2 had been around for a while and the K1 was rather new. The reflector was fun and helpful. As Elecraft has grown and added more products it has gathered many new customers. While I do miss those early days I am very glad how Elecraft has grown: steadily and wisely. I also miss my Hodaka, my Post Versalog II sliderule, and 1960's prices.

I like to run digital at 50 W max, to lessen the strain on the equipment. The advantage of this method was that the power on the band in use was not reduced, so that when going back to SW or SSB, the full power was still set. The "K3 recommended " method does a fine job, but requires reducing the power to 50 W. Then, when one returns to CW or SSB, you are still at 50W, since power is not saved "per mode". > > Would a software change which saves power "per mode" as well as "per band" be possible?

The power output is measured and the MCU compares that output with the power requested by the power knob. If the actual power is less than requested, the drive will be increased to make the output equal to that requested. So if the audio drive is not sufficient, yes power will be lower than the requested value and the transceiver will go to full possible drive (and excess power will be produced when the audio output is increased). >> >> For those who are concerned about the ALC meter indication, the onset of ALC is at the 5th bar on the meter - the 4th bar is the "NO ALC" point for the K3 (KX3, KX2 and K3S). >> >> For the K2, increase the audio until you have ALC indicated, and then back off the audio just enough that no bars are displayed. >> >> The real key is to set the audio as instructed in the manual, and then control the power with the power knob.

Elecraft has had a profound impact on me. It started with the K1. I bought two kits, one for myself and one for my elmer (ki7el). We had a wonderful time building them, and then I was shocked when it ran cw circles around my fully loaded 706m2! That experience ultimately lead me to a much deeper understanding of every aspect of radio engineering. Bolstered by my success with the K1, I built a K2, and then became a kit junky. When the K3 was announced, I pre-ordered without a second thought. Today, I also have a KX3. The K1 remains my backpacking rig of choice. The KX3 travels with me to ki7el's place roughly once a month for multi-op contesting -- the rig, the amp, and the pan-adaptor all fit in a shoulder bag :). James (ki7el) rocks a K2/100, so for multi-mode contests, I try to bring my K2/10 and KXPA100 so we're both running K2s. Finally, the K3 is the beloved center of my home station. Over the years, we've both become convinced that nothing beats an Elecraft. They aren't inexpensive, but you really do get what you pay for in quality, survivability, serviceability, and support. -kb7psg From vr2xmc at yahoo.com.hk Sun Jan 8 08:24:22 2017 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Sun, 8 Jan 2017 13:24:22 +0000 (UTC) Subject: [Elecraft] Elecraft Support In-Reply-To: References: <011c3fd5-7839-9c6d-c3d3-53e0a123ba0f@gmail.com> Message-ID: <928515186.657948.1483881862591@mail.yahoo.com> Don and all, Yes, I have been contacting Gary for more than a decade for various elecraft support matters. ?My first contact with him was for my K2# 14xx.

Re: [Elecraft] Elecraft Support Jim and all, Yes, I remember those "good old days" when the only Elecraft support person was Gary (I was one of the K2 Field Testers).? Unfortunately as the Elecraft product line grew, the number of support persons has grown too - it now numbers 4 - David, Craig, Howard and Gary, and the Monday morning support email load is large. Problems that the support staff cannot handle are still passed along to the engineers, but that may be in the background while the support people handle the major communications back to the customer. Yes, I am close to the Elecraft team (particularly the support and sales folks), and do most of the repairs on the K2 and other "thru-hole" kits in the Elecraft line.? So I am quite familiar with that part of their operation as well as their problems.? Personal phone numbers are no longer given out (protections for the employees except in extreme cases), but you will still receive personalized customer support service via email or they will often phone customers with problems. I do serve as support for those "Thru-hole" products when Gary is not available, and I can say for myself that (from me) you will receive extended personal support when required - yes even help with a lifted solder pad. I am in North Carolina, and am in a different time zone than Elecraft, but that makes little difference,? we still communicate with each other and the customers when the need arises. 73, Don W3FPR From ed.n5dg at gmail.com Sun Jan 8 09:18:09 2017 From: ed.n5dg at gmail.com (Ed Stallman) Date: Sun, 8 Jan 2017 08:18:09 -0600 Subject: [Elecraft] K3: I must have changed something ?

There are 4 filter settings for each mode. These are not "roofing filters" as used in the K3, but IF crystal filters. The filter type in the base K2 is of a Cohn design and the width can be changed as I stated above. Its design width is about 500Hz and gives a nice passband from about 1.5kHz down to about 200Hz. It can be widened out to SSB listening levels, but the passband becomes quite ragged at those wider widths. It is however suitable for SSB listening. The filter on the KSB2 option board has a nice flat passband. The KSB2 option (for SSB) has a fixed width 7 pole filter. The early filters were 2.1kHz width, but more recent filters are 2.4kHz. Elecraft has a capacitor kit which will allow you to change the filter width. The crystals used in the K2 filter were upgraded to better speced crystals at SN 2560. I would recommend that K2s below that SN be upgraded with the new crystals. Elecraft sells a kit of matched crystals at a very reasonable price a set of 7 for the base K2 or a set of 14 for both the base K2 and the KSB2 option. 73, Don W3FPR On 1/8/2017 11:10 AM, Mike Smith VE9AA wrote: > It's Mike, VE9AA...I own a K3 but almost never use it (only for FD and > portable ops -I've used it twice in my year of ownership) > > I am thinking about maybe buying a used K2/10 with many options,(no DSP > board I don't think) but as I don't know a thing about the K2 (and after > reviewing the Elecraft website) I had this hopefully simple question.

The K2 does not have individual filters like the K3. It has a set of serial crystals in a lattice filter arrangement [sic] that can be voltage biased to yield various effective filter widths from very narrow to broad. There are provisions to select three/four pre-programed filter widths per mode [not quite sure of this one]. The various widths are set up in the filter calibration mode of the K2. W3FPR Don Wilheim's site has all sorts of information on general principles as well as step-by-step instructions for setting the filter widths in the K2. An auxiliary program called "Spectogram" is used to portray the filter widths on the computer screen so that one can see the shape/bandwidth of the filter during setup. In my experience, the filtering system in the K2 is quite effective.

I had my KX3, s/n045, less than 10days and a problem developed. I shot an email to Elecraft at 10pm on a Sunday nite, shortly Wayne answered me, much to my surprise ! It was an early firmware problem and he said he'd be on it Monday morning ! I get an email from him Tuesday to call him personally. He spent an hour on the phone with me while I reloaded firmware and set the radio up again ! I've not had a problem since in almost 5 years now. I was so impressed with Wayne's personal service and help ! I'll never buy anything but Elecraft products ever again !

I have an old amp (two-digit serial number), and it has performed flawlessly until yesterday. Suddenly the Operate-Standby button stopped working, and then I noticed that other buttons worked, but did strange things. The cure was simply to take off the front panel and reseat the two ribbon connectors. Actually I could only reseat the large connector at the panel end, and the small one at the board it plugs into in the main body. The other end of the large connector is at the back of the amp and not accessible without considerable disassembly. And the panel end of the small connector was stuck on so tight that I was afraid I would break something in removal. But reseating 2 of the 4 possible connectors did the trick. Now it seems to be back to normal. 73, andy ae6y From matt.vk2rq at gmail.com Sun Jan 8 16:16:46 2017 From: matt.vk2rq at gmail.com (Matt Maguire) Date: Mon, 9 Jan 2017 08:16:46 +1100 Subject: [Elecraft] Problem with my K2 In-Reply-To: References: Message-ID: <7DA76B0A-3A7D-4C72-93C7-2952DE899F22@gmail.com> What happens if you run it off a battery with a dummy load connected?

I have built a few radios that were surface mount and they can be a little more of a challenge than through hole,but not nearly as hard as I initially thought they would be, just a but different in the thought process and work.I think Elecraft would be hard pressed to sell a lot of K3's that were 100% in Kit form (as in solder the boards). The K2 was a great radio and I really enjoyed building it (and in a moment of foolishness I sold it). Of the few radios I regret selling the ones I actually built are the ones I regret the most.

My dad had worked on them during WWII and bought half a dozen when they were cheap in the 50s. When I opened them up I found each part was placed just so; the resistor color bands all lined up with the tolerance bands in lock step. I just could not bring myself to touch them with a soldering iron even years after dad had passed away. It would be like dismantling a sculpture. 73, Kevin.

It sounds more like a source of broadband noise. Check your power supply and any "wall-wart" supplies in the vicinity. An open antenna jack can pick up noise, so test again with a dummy load connected. If the noise persists, I think you will be looking for a bad solder connection in the K2. 73, Don W3FPR On 1/8/2017 1:08 PM, Bjarne Birch wrote: > On 20 m I have something that sounds like a spurious, I don't know what it is.

Mine came on high-fan often when on RTTY, or [fruitlessly] calling CQ in SS CW on Sun. I finally moved it out of it's "cubbyhole" under the shelf assembly, and it stayed on low fan all the time, which I couldn't hear with the cans on. For my K2/100, the heat sink got very hot with repeated [unanswered] CQ's and on RTTY. I mounted a computer fan on top of the heatsink with a tab of velcro, blowing down. Heat sink stayed cool to the touch with 80-90 W on RTTY. I am repeatedly amazed by thermodynamics.

It hears just about as good as my K3 with the upgraded synthesizers in my humble opinion. I purchased an older kit that went up for sale last summer. It has every option including the KDSP2. CW sounds so sweet. I would really like to try the KAF2 just to hear the difference on CW. I find myself bypassing the KDSP2 on strong signals, just to hear the crystal filters by themselves. The KDSP2 really shines on weak signal work though. It's very satisfying to finish the K2 and have it work so well. I also get great audio reports on SSB. Long live the K2!!

I got the KAT100 working last month, and I am working on the KPA100 now. It hears just about as good as my K3 with the upgraded synthesizers in my humble opinion. I purchased an older kit that went up for sale last summer. It has every option including the KDSP2. CW sounds so sweet. I would really like to try the KAF2 just to hear the difference on CW. I find myself bypassing the KDSP2 on strong signals, just to hear the crystal filters by themselves. The KDSP2 really shines on weak signal work though. It's very satisfying to finish the K2 and have it work so well. I also get great audio reports on SSB. Long live the K2!!

(I wouldn't even call them "roofing" filters.) They are analog filters, which can improve rejection of adjacent signals which might overload the ADC. They will not, however, reject the "audio image", on the other side of zero beat. I'd expect, especially during contests, the the effect would show up once in a while, probably making a weak signal totally unintelligible. Has anyone noticed this effect? Especially on CW, it would be fairly unlikely, as the interfering signal would have to fall within the narrow passband on the other side of zero beat. 73, Scott K9MA On 1/9/2017 11:54, Ignacy wrote: > Perhaps as it should be.

Those 2 are the major ones governing how much noise you hear on a band between pauses in speech or between letters/words on CW. The article gives you guidelines for determining the best setting for the type of operating you do and your personal preferences. For the other settings, I find the defaults are quite suitable, but you are welcome to experiment. 73, Don W3FPR On 1/9/2017 2:31 PM, NOEL POULIN wrote: > Hi, > I am a new owner of a K3S. > I would like to know the best AGC SETTINGS for the K3S > I mean AGC DCY, AGC HLD, AGC PLS, AGC SLP,AGC THR. > I am not very satisfied with the default setting... > Most of the time I'm working CW, RTTY...in contests From nbpriddy at aol.com Mon Jan 9 15:26:56 2017 From: nbpriddy at aol.com (Nathern Priddy) Date: Mon, 9 Jan 2017 15:26:56 -0500 Subject: [Elecraft] Problem with N1MM+ ansd My K3 in ARRL RTTY Test Message-ID: <15984e98cce-4eeb-3bb08@webprd-m69.mail.aol.com> Did anyone else have the problem I had using MMTTY in N1MM+ with my K3 in the ARRL RTTY Contest?

With that software setup, I could click on a new RTTY spot in Spot Collector, and the K3 stayed in FSK D mode. When I switched back to N1MM+, I had the origninal problem for the rest of the contest.

I suggest starting with the discussion on Don's (W3FPR) web site - http://www.w3fpr.com/. Go to the "Noisy K3? - Adjust your AGC Settings" section. That paper has a very good explanations of the K3 AGC system operation. For a discussion of each control with suggested values and why beyond the Elecraft Operators Manual. http://www.ve1zac.com/Jeff%20Smith%20K3%20AGC%20R1.pdf You can chase your tail until you understand the settings and how they interact. Go to Fred's (KE7F) "K3 AGC Story" sections at http://www.ke7x.com/home. Fred has written tutorials on deciphering the Elecraft manuals with step by step instructions. I do not have any of his books; however they get very good reviews on this reflector! Personally - I refer to the transfer graphs. That helped me understand the AGC operation on my K3 & KX3. http://www.ke7x.com/home/miscellaneous-k3-information/agc-4-51. I have a laminated copy of this graph in my operating desk! Also refer to these as well. http://www.cliftonlaboratories.com/elecraft_k3_agc_and_s-meter.htm. The Elecraft AGC system allows you a large room for adjustment to allow different modes of operation and preferences. Unfortunately this also means that there is a learning curve to get it "Your Way"! "Your Way" may change depending on the mode and band conditions. Hopes this helps a little. 73 George AI4VZ ----- From: NOEL POULIN Hi, I am a new owner of a K3S.

For those who prefer to use AFSK A, the correct selection is AFSK. For PSK and other sound card modes using DATA A on the K3, you should select PSK in the boxes beside PSK. Also, there is a check box in the Configurer under Mode Control called "Always use packet spot mode". This check box is mainly there for people who use N1MM+ outside of contests, or perhaps in some multi-mode contests. It should not be checked in single-mode contests, nor in multi-mode contests if you have not first set up the band plan limits in the Bandmap window to be appropriate for the particular contest. The appropriate sub-band limits change depending on the contest mode, and they are also different between domestic vs. DX contests. You can limit the problems this setting can cause to a certain extent by ensuring that the Mode Category in the Contest Setup dialog is set correctly (e.g. do not use a multi-mode category for a single-mode contest). 73, Rich VE3KI K5VIP wrote: > Whenever I clicked on a new spot in the N1MM+ bandspread window, the mode switched from FSK D to USB.

During the weekend RTTY contest, I noticed that I was getting very low audio volumes coming into my MacIntosh when the AGC was engaged (both in fast and slow modes). I tried to find how to adjust the volume in the K3S manual, but only found the procedure by reading all the CONFIG items in the back of the manual. The LIN OUT setting does the job. The manual warns that values higher than 10 may result in overdrive of the soundcard or saturation of the KIO3?s isolation transformers. I found a setting of 40 seemed to work well.

In the early days of radio, you *had* to build your own station because ready-built equipment was not available (unless you were one of the 1% and could pay someone to do it for you). In those days, you could build something close to state-or-the-art on your kitchen table. But building a spark transmitter or a 2-tube MOPA rig was far simpler than building a state-of-the-art multi-band synthesized radio would be today. I think you can make a good argument that the little projects that hams do build today - for example some Arduino gizmo with a dozen parts - is of similar complexity to the all-homebrew stations of old.

With a little practice it isn't difficult. Especially if you know how to make a good solder joint on a through hole part The hardest part is getting magnification. There are some very affordable stereo microscopes available, you will probably want 20x magnification. On Amazon I have seen prices in the $137 range on a quick search. I was able to convince my eye doctor to prescribe a pair of low vision aid glasses, not quite 20x, that work really well for the larger, 0603 and .5mm pitch 100 pin QFPs. These things have coke bottle lenses and they put the soldering iron a few inches from my nose ;) If you are into making your own circuits you will find that 0603 parts, as well as SOT23 work well on .1 pitch protoboard, if you are creative enough. Other helpful hints: Buy the finest diameter leaded solder you can find, no need to make your life any more difficult on this scale with lead free solder. Buy a flux pen. Sometimes a little bit of extra flux will help. One advantage of SMT parts is they are VERY inexpensive, at least resistors and capacitors, and you can store an awful lot of them in a small space. Other resources are Schmartboards, these are used to adapt SMT ICs to .1 lead pitch perfboard. Sparkfun and Adafruit are great resources as well if you want to operate at a slightly higher level of abstraction then the base hardware level. If you ENJOY building it yourself, don't let small parts intimidate you. 73, KD8CIV On Mon, 2017-01-09 at 18:29 -0600, Kevin wrote: > I don't either.

I haven't gone to the microscope yet, but a magnifier with a circular fluorescent is a standard feature on my bench as is a cheap over-the-eyeglasses magnifier. I have a hot air rework station I got from Sparkfun which enabled me to remove the existing resistor on my K3 to install the KPod power mod. It is also great for shrink wrap tubing. The difference between today and the old days is that then you got one component per package. Now you get many functions in one package. The new synth board for the K3 is a fine example. Darn few packages, but lots of function. 73 Bill AE6JV On 1/9/17 at 6:08 PM, crustacean at brig-elec.com (John Pitz) wrote: >Guys, don't let SMT parts intimidate you.

If a strong signal overloads the ADC, all bets are off. Without the audio filters, that strong signal could be quite far away. (The other low pass filters seem to cut off around 14 kHz.) In any case, it could be well outside your DSP passband. The optional audio filters are two pole active low pass filters, with bandwidths of something like 700 Hz and 1.6 kHz. There are two: I and Q. But, because the IF is baseband, where both sides of zero beat are present, these filters can reject signals on the "wrong" side. Indeed, they couldn't, or the I/Q decoding couldn't remove one of them. 73, Scott K9MA On 1/9/2017 17:23, Brendon Whateley wrote: > I'm not sure why you would think this is a problem, the "other side" > signal is removed by the I/Q decoding technique, not by filtering.

With AGC on, and LIN OUT set to default (10), the digital level via the USB interface was -22 dBFS (true peak). With LIN OUT set to 40, the gain is increased by 12 dB and thus peaks to -10 dBFS on the USB interface. This is a much more sensible level. I don't know if this is saturating the transformers, but as I don't use the analogue line output it doesn't matter in my case. I don't understand why the gain structure of the rig is designed so that have to have the output either too low on USB or so high it risks saturating the transformers on analogue. When operating WSJT-X, I leave LIN OUT at 10, turn AGC off and adjust the RF gain to get the level I want. 73, Richard G4DYA From no9e at arrl.net Tue Jan 10 10:13:52 2017 From: no9e at arrl.net (Ignacy) Date: Tue, 10 Jan 2017 08:13:52 -0700 (MST) Subject: [Elecraft] kx3 receiver versus K3s receiver In-Reply-To: <4bda8c6e-c728-b9a4-9d09-05b416f1793a@sdellington.us> References: <033d01d26928$b64ccae0$22e660a0$@cox.net> <1483984466052-7625595.post@n2.nabble.com> <4bda8c6e-c728-b9a4-9d09-05b416f1793a@sdellington.us> Message-ID: <1484061232427-7625629.post@n2.nabble.com> To eliminate problems caused by the I/Q decoding and reduce costs, KX3S will include direct sampling.

I have the amp go to 70c sometimes, that is when the HIGHEST speed fan kicks in, NOT 65c. Not a problem, many RTTY contests and still works fine! The room ambient temp has a lot to do with the temp of the KPA500, in the summer I hit the 70c a lot more often than I do in the winter, when my shack is 63-65F.

The manual states that it is typically the opposite, with 14 mHz 0.2 - 0.3W lower. I checked the voltage across a dummy load with my scope, converting P-P to RMS and the using the 50 ohm load to calculate the output in Watts. Working into 50 ohms gives me 2.7W out on 7 and 3.6W on 14. Seems like the 14 mHz output is about right, but something is wrong with 7 mHz. The manual suggested squeezing the turns on L2 to occupy about 60% of the circumference of the core. Rather than improving things, the output on 7 mHz was reduced to about 2.3W, so I went back to the normal distribution of the coils. All of this is with a 14.0VDC well filtered and regulated power supply. In each case the VSWR was reported at 1.0 with the 50 ohm dummy load. Any ideas anyone?

If your installation is static, or relatively static, you can duct cooling air from some place where the noise is "OK" to a properly located input. OR, you can put the duct on the outlet and put a suction device somewhere remote where the noise won't be troubling. Or, you could replace the heatsink altogether in favor of a water cooling heat exchanger... Or, other many varied solutions depending on your requirements and acceptable trade-offs. Thermal design is a hobby unto itself... so many options... I find it a lot of fun. 73. ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 1/10/2017 11:21 AM, Ron D'Eau Claire wrote: > With an adequate sized heat sink, one could build a legal-limit solid state > amplifier with no fan whatsoever, but the most Hams want physically smaller > equipment even if it requires cooling fans.

What is the Speaker slider on the computer set to? Open the playback controls - normally set it to about 75%. The "meter" in the computer soundcard display will not tell you the whole story. Go to the Playback Controls to see the slider (Windows - Mac or Linux may be different). Make sure there is nothing plugged into LINE IN (it overrides the Codec line in). You may want to insert a plug into the LINE IN jack and quickly remove it just to make certain the contacts in the jack close properly. You must set the MIC menu entry to LINE. Set the audio level correctly (you can do that in TX TEST or connected to a dummy load so you do not transmit RF). Tell your software application to "transmit", then adjust the "MIC" gain (actually LINE if you have set the menu correctly) until you have 4 bars solid with the 5th bar flashing. If you cannot achieve that audio level by manipulating to Speaker slider on the computer and the MIC Gain on the K3S, something is awry - contact K3support for additional assistance. 73, Don W3FPR On 1/10/2017 5:16 PM, Dan wrote: > Did RU this past weekend and could not get KIO3B to XMIT-Receive is fine using MMTTY and N1MM.

DATR A can also be made to work, but my experience with AFSK A is much better. FSK D does not use the sound card for transmission. Make sure your computer is producing enough output drive. On my Mac I need to go to System Preferences -> Sound and raise the output volume all the way. Make sure your application is addressing the correct USB device. (Don't ask how I know.)

I've been using the original SDRplay for a few months now and like the 2mhz spectrum display using my K3's IF out and Win4K3suite. Win4K3 (http://va2fsq.com/ ) has added support for the new release SDRPlay RSP2 and likely will be doing additional enhancements to take advantage of the SDRPlay RSP2 expanded device features. It is really nice in that you can have 2mhz of spectrum in the panadapter display in Win4K3 Suite. That said, CWSkimmer does not yet support the SDRplay, but there are some doing some work arounds with virtual audio cables (VAC). So, using a T connector, I also use the IF Out with my LP-Pan2 and Steinberg UR22 soundcard with CWSkimmer. The noise floor of the SDRPlay is really good and with adjustments, I am able to see very weak signals coming out of the K3 IF. 73 Doug NA1DX -- Doug Ellmore, Sr. doug at ellmore.net From vr2xmc at yahoo.com.hk Wed Jan 11 04:30:57 2017 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Wed, 11 Jan 2017 09:30:57 +0000 (UTC) Subject: [Elecraft] OT: a short presentation to a group of primary school children about radio References: <1726150408.1329450.1484127057061.ref@mail.yahoo.com> Message-ID: <1726150408.1329450.1484127057061@mail.yahoo.com> Hello Elecrafters, It is off-topic and please press delete if you don't want to read.

I'm strictly single op and no SO2R here so a single feedline to my remote antenna relay. I bought the ACOM 1500 because I felt I needed additional power at times. It is serving that need nicely. I'm slowly getting more accustomed to the operation of a manual tune amplifier after a few years of automated operation of the Electraft line. But the KPA/KAT combo is nice for instant-on and quiet idling. I usually leave my rig on all day if I'm in the house to grab the quick DX spot. At the first spot of the day of course I need to wait 3 minutes plus tuning time before getting in the pileup. I find that 3+ minutes torture. The ACOM 1500 fan is also a bit annoying. So I've decided to put the KPA/KAT back in service in the following way. Since I have a KANT3a in my K3S I will connect the KPA/KAT to ANT1 and the ACOM 1500 to ANT2. Selection of the ANT line from the K3S will therefore exclusively provide RF to one or the other. Thanks to the internal preamp of the K3S the DIGOUT1 line is freed up to provide a signal to switch the single feedline to the antenna farm between the KPA/KAT and ACOM 1500 outputs. I haven't yet selected a legal limit A/B relay but there appear to be several available. A separate relay also driven by DIGOUT1 will switch the KEY line between the amps as well. The KPA/KAT will connect via the AUX bus as usual to provide the former automation including setting KPA per-band power levels. I'll need to put the KPA in Standby to go "barefoot" and I already have the barefoot level set to an appropriate value for the ACOM 1500. The normal drive power to the KPA is also within the range of power I already use to tune the ACOM so no problems there if I forget to put the KPA in Standby. Since DIGOUT1 is per-band and per-antenna the appropriate setting will be made for each. Of course DIGOUT1 being open collector it will need to be pulled up and appropriate buffering added to ensure safe operation of the relay coils. So with two button presses I can switch between the two amps and the two ANT connections eliminates the input switching relay and wiring. Of course if a KPA1500/KAT1500 makes a debut all of this will be replaced in a heartbeat!!!

Scratched my head a while and finally decided the K3S was putting out a spurious signal of some kind. No problem with a dummy load because it didn?t care what frequencies it was seeing. There was an additional problem: No transmit with mode set to USB or LSB. Change mode to CW, tap the key, switch back to USB, output fine. So I sent the K3S off to Elecraft. Yep!

The problem was indeed a cable - it had fallen out completely! The rig is in a tough place to get at the back, and I never noticed. The "interrupter" can only be fastened with a wrench, and I had not done that, with the results noted. Now I have found the wrench in my tool box, and I think it will stay in place! Harry, You are right about the requirement to pause - now I can see that, with the rest of the problems solved. I guess you cannot expect information transfer through thin air!

I use a Six Pak driven by a pair of ACC-driven band decoders for antenna switching between the two amps because it's there already, used for SO2R antenna switching when I'm physically at the station. That would be overkill for you - as you say, you just need a SPDT RF relay like the ancient Dow-Key's we used to use for T-R switching in the 60's. You could even buy a Six Pak replacement part open frame relay from WX0B and mount it in a mini-box with some SO-239s, very inexpensive. If I were you, I'd use a simple SPST switch instead of programming the many combinations of DIGOUT1. I run Key Out from the K3 to the Alpha 87A and key the KPA500 through the ACC cable. If I neglect to put the KPA in STBY when using the Alpha, it keys in parallel but has no drive. No extra relay, no problem. You could also key both amps concurrently with the K3 Key Out line and a Y-splitter.

Never fear, that serial number is fully up to date with all mods that are available for the K2. It may have MCU 2.04P while the newest is 2.04r, but the only difference between those two firmware releases is that 2.04r locks the sidetone source at U8-4. MCU 2.04P allows the sidetone source to be switched between U6-25 and U8-4 in support of very old K2s. The number of support calls and emails saying "I have lost my sidetone" prompted Elecraft to make that change. So if you have MCU 2.04P and lose your sidetone, just check the setting of the sidetone source - it is easy to change, go to the STL menu and edit the parameter - tap the DISPLAY button to toggle the sidetone source. You could also update the firmware to 2.04r (E610002 - FWK2MCU) 73, Don W3FPR On 1/11/2017 8:10 PM, ac5p at sbcglobal.net wrote: > Anyone have a K2 close to serial 6900 that can tell me mo/yr purchased?

What is the Speaker slider on the computer set to? Open the playback controls - normally set it to about 75%. The "meter" in the computer soundcard display will not tell you the whole story. Go to the Playback Controls to see the slider (Windows - Mac or Linux may be different). Make sure there is nothing plugged into LINE IN (it overrides the Codec line in). You may want to insert a plug into the LINE IN jack and quickly remove it just to make certain the contacts in the jack close properly. You must set the MIC menu entry to LINE. Set the audio level correctly (you can do that in TX TEST or connected to a dummy load so you do not transmit RF). Tell your software application to "transmit", then adjust the "MIC" gain (actually LINE if you have set the menu correctly) until you have 4 bars solid with the 5th bar flashing. If you cannot achieve that audio level by manipulating to Speaker slider on the computer and the MIC Gain on the K3S, something is awry - contact K3support for additional assistance. 73, Don W3FPR On 1/10/2017 5:16 PM, Dan wrote: > Did RU this past weekend and could not get KIO3B to XMIT-Receive is fine using MMTTY and N1MM.

I've been using the original SDRplay for a few months now and like the 2mhz spectrum display using my K3's IF out and Win4K3suite. Win4K3 (http://va2fsq.com/ ) has added support for the new release SDRPlay RSP2 and likely will be doing additional enhancements to take advantage of the SDRPlay RSP2 expanded device features. It is really nice in that you can have 2mhz of spectrum in the panadapter display in Win4K3 Suite. That said, CWSkimmer does not yet support the SDRplay, but there are some doing some work arounds with virtual audio cables (VAC). So, using a T connector, I also use the IF Out with my LP-Pan2 and Steinberg UR22 soundcard with CWSkimmer. The noise floor of the SDRPlay is really good and with adjustments, I am able to see very weak signals coming out of the K3 IF. 73 Doug NA1DX -- Doug Ellmore, Sr. doug at ellmore.net ------------------------------ Message: 10 Date: Wed, 11 Jan 2017 09:30:57 +0000 (UTC) From: Johnny Siu To: Elecraft Reflector Subject: [Elecraft] OT: a short presentation to a group of primary school children about radio Message-ID: <1726150408.1329450.1484127057061 at mail.yahoo.com> Content-Type: text/plain; charset=UTF-8 Hello Elecrafters, It is off-topic and please press delete if you don't want to read.

I'm strictly single op and no SO2R here so a single feedline to my remote antenna relay. I bought the ACOM 1500 because I felt I needed additional power at times. It is serving that need nicely. I'm slowly getting more accustomed to the operation of a manual tune amplifier after a few years of automated operation of the Electraft line. But the KPA/KAT combo is nice for instant-on and quiet idling. I usually leave my rig on all day if I'm in the house to grab the quick DX spot. At the first spot of the day of course I need to wait 3 minutes plus tuning time before getting in the pileup. I find that 3+ minutes torture. The ACOM 1500 fan is also a bit annoying. So I've decided to put the KPA/KAT back in service in the following way. Since I have a KANT3a in my K3S I will connect the KPA/KAT to ANT1 and the ACOM 1500 to ANT2. Selection of the ANT line from the K3S will therefore exclusively provide RF to one or the other. Thanks to the internal preamp of the K3S the DIGOUT1 line is freed up to provide a signal to switch the single feedline to the antenna farm between the KPA/KAT and ACOM 1500 outputs. I haven't yet selected a legal limit A/B relay but there appear to be several available. A separate relay also driven by DIGOUT1 will switch the KEY line between the amps as well. The KPA/KAT will connect via the AUX bus as usual to provide the former automation including setting KPA per-band power levels. I'll need to put the KPA in Standby to go "barefoot" and I already have the barefoot level set to an appropriate value for the ACOM 1500. The normal drive power to the KPA is also within the range of power I already use to tune the ACOM so no problems there if I forget to put the KPA in Standby. Since DIGOUT1 is per-band and per-antenna the appropriate setting will be made for each. Of course DIGOUT1 being open collector it will need to be pulled up and appropriate buffering added to ensure safe operation of the relay coils. So with two button presses I can switch between the two amps and the two ANT connections eliminates the input switching relay and wiring. Of course if a KPA1500/KAT1500 makes a debut all of this will be replaced in a heartbeat!!! Comments or suggestions welcomed! 73 jim ab3cv ------------------------------ Message: 13 Date: Wed, 11 Jan 2017 09:45:11 -0700 (MST) From: KV5J To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Tandem operation of KPA and ACOM 1500 Message-ID: <1484153111113-7625647.post at n2.nabble.com> Content-Type: text/plain; charset=us-ascii The KANT3a was a great add-on for those that don't want or need the internal tuner.

Everything seems to work "just as per" with the exception of the frequency tracking function on receive. This was running at one time; I did a tune every time the K3 crossed a frequency boundary, and it seemed to track thereafter. Now it won't track - no relay noise from one end of the band to the other. It seems to remember specific settings, and will re-tune on transmit, but does not re-tune on VFO movement. (No split freq, either.) There is no KAT3 in the K3, so CONFIG:KAT3 indicates "not inSt", but tap 1 toggles getween KAT500N and KAT500Y, and was left in the latter position. This is no big deal, but it would be handy if the KAT500 would return on receive to the last settings for that frequency, rather than wait for a transmit pulse. Besides, it is supposed to do just that! Any thoughts?

The problem was indeed a cable - it had fallen out completely! The rig is in a tough place to get at the back, and I never noticed. The "interrupter" can only be fastened with a wrench, and I had not done that, with the results noted. Now I have found the wrench in my tool box, and I think it will stay in place! Harry, You are right about the requirement to pause - now I can see that, with the rest of the problems solved. I guess you cannot expect information transfer through thin air!

I use a Six Pak driven by a pair of ACC-driven band decoders for antenna switching between the two amps because it's there already, used for SO2R antenna switching when I'm physically at the station. That would be overkill for you - as you say, you just need a SPDT RF relay like the ancient Dow-Key's we used to use for T-R switching in the 60's. You could even buy a Six Pak replacement part open frame relay from WX0B and mount it in a mini-box with some SO-239s, very inexpensive. If I were you, I'd use a simple SPST switch instead of programming the many combinations of DIGOUT1. I run Key Out from the K3 to the Alpha 87A and key the KPA500 through the ACC cable. If I neglect to put the KPA in STBY when using the Alpha, it keys in parallel but has no drive. No extra relay, no problem. You could also key both amps concurrently with the K3 Key Out line and a Y-splitter.

Message-ID: <980bb55b-7b0d-0202-7ada-bd31f0c1e9cf at embarqmail.com> Content-Type: text/plain; charset=utf-8; format=flowed Mike, I recently did some investigation of my repair records, and discovered that a K2 serial number of 69xx dates back to 2011 or 2012. Never fear, that serial number is fully up to date with all mods that are available for the K2. It may have MCU 2.04P while the newest is 2.04r, but the only difference between those two firmware releases is that 2.04r locks the sidetone source at U8-4. MCU 2.04P allows the sidetone source to be switched between U6-25 and U8-4 in support of very old K2s. The number of support calls and emails saying "I have lost my sidetone" prompted Elecraft to make that change. So if you have MCU 2.04P and lose your sidetone, just check the setting of the sidetone source - it is easy to change, go to the STL menu and edit the parameter - tap the DISPLAY button to toggle the sidetone source. You could also update the firmware to 2.04r (E610002 - FWK2MCU) 73, Don W3FPR On 1/11/2017 8:10 PM, ac5p at sbcglobal.net wrote: > Anyone have a K2 close to serial 6900 that can tell me mo/yr purchased?

Better common mode chokes on your feedline(s). See the information by Jim Brown K9YC at http://audiosystemsgroup.com/RFI-Ham.pdf. If you still have problems after taking those measures, then use ferites on cables as a last resort solution. The reason I say this is because if you have RF interfering with the wiring in your station, you likely have similar interference on all wires in your station - you can fix one or two, but another similar problem will rear its ugly head later on. If you fix the problem at its source, you will fix a lot of "strange behaviors". 73, Don W3FPR On 1/12/2017 11:05 AM, John Stengrevics wrote: > Hi Nick, > > Thanks for the suggestion!

For whatever reason, this always seems to be worse on 20 meters than other bands with home electronics. Then I don't know of an option for offending equipment other than a few turns through some hefty ferrite on the resonant cable(s). (As I'm sure you know, a lot of home electronics are poorly executed with respect to keeping out common mode currents... Jim Brown K9YC has published a lot of really great information about this state of affairs. Sometimes the entry point for common mode noise isn't what you would expect, too.) If you're like me, and you have a dipole antenna mounted on your roof, getting it up a little higher may help some too...or just learning to live with lower power output. My threshold at home with digital modes on 20m is about 27 watts... below that, everything is fine. Above that, everything is terrible. Fortunately, most of the time I don't even need that much to make a successful contact, and even with modes like WinLink, 15 watts is plenty.

If the problem is happening because of common mode on the USB cable, there is no physical RTS line involved like there would be in an old-style COM/RS232 device- there is only serial data going across a USB cable to a logical COM device inside the K3S. It most likely wouldn't change anything in this case.

The set RTS/DTR/Break and clear RTS/DTR/Break commands are much more robust than sending serial data via USB. Using RTS is *always* more robust (and less susceptible to RFI) that using CAT commands for TS?RX switching. 73, ...

It has the RTS and DTR signals and they are properly routed to the K3S. The RS-232 circuits in the K3S are retained just like as they were with the K3. 73, Don W3FPR On 1/12/2017 1:15 PM, Nicklas Johnson wrote: > Unless I'm mistaken, doesn't the K3S connect directly via USB though?

One would be an op-code (probably 8 bits) plus 5 more bytes, versus the other being just an op code. So it's odds of garbling 1 or more bits out of 8 versus 1 or more bits out of ~48. Probably mitigates the problem somewhat, but mostly likely won't make it completely go away. The best thing still will be attenuating the common mode noise on the USB cable, IMO... keep it out of there in the first place.

I'm in DATA-A mode. I'm using the K3s internal USB audio device. I have the power slider on WSJT near the max, setting it completely to the max causes K3s audio input overload regardless of where I set the Windows Mixer input slider. I have the Windows mixer levels for the K3 set to -7.7db. With these settings the K3 Input level shown on the mixer panel is about 70% when tone is asserted by Tune which seems acceptable, i.e. not saturated. I then adjust the LineIn level on the K3s. When the level is too low (e.g. 3) the ALC meter pulses with about a 0.5 second rate between no bars and 5 bars. LineIn set to 4 shows the same pulsing but between 4.5 to 6 bars. Setting LineIn to 5 yield a more stable display but still oscillating between 6-7 bars. This pulsing/oscillation doesn't seem right to me. With a steady Tune tone from WSJT I would expect a steady rather than pulsing/oscillating ALC display. BTW, this is true even in K3S Test mode so no RF is being generated. PC is bonded to the K3s rather well. I even removed the K3S Aux connector to ensure something wasn't getting in that way. I'm also seeing a power spike on the initial tone assertion in Echo mode. So I did a TX gain calibration at 5 and 50w and still see the same. The power spike is what got me looking more closely at the ALC levels. My next test will be putting a scope on the K3S to look to see if there really is a RF power spike or something is screwy with my newish ACOM 1500. I haven't seen any power spiking on CW modes. I'd like to also look at the audio input level from WSJT but don't have a good idea on how to do that since the internal K3S audio codec is being used. Perhaps the headphone out level would show the spike (if it is being generated by WSJT) as well if AGC is off? Suggestions welcomed! 73 jim ab3cv .

To do that, you are still sending data over the USB link. Not the same data, but data none the less. So, any RF ingress into the USB systems (at either end of the cable!) Can still cause trouble. Note, clip-on ferrite cores have very little effect at MF/HF frequencies, unless you can wrap several turns of the USB cable through them. And even then, it depends on what the exact problem is where and how the RF get's in. I often wonder why we don't use fibre optic links for rig control and audio. TosLink cable and devices are available for the audio, and it's relatively trivial to send (RS232 like) data down a fibre too. I'll get my coat... 73. Dave G0WBX.

I get that, it's a hobby. For sure, been there done that. But all you have done for the moment is put the snarling dog in a cage where it can't bite. If you ever run an amp the trouble is likely to return in some form. You still have the snarling dog. And there are unanswered oddities like why the RFI only affected the one sequence of commands. For others reading this thread, the exhortations for VOX or PTT are very well taken, particularly where deciding on methodology is part of planning. Having a PTT and not-PTT signal available to the station *system* can be very useful for such things as shutting off remote RX amps during transmit. Many PC station programs like N1MM+ can add transfer delays only where they apply, as do WinKey equipped devices which can apply CW key speed related "word space" intervals. Not-PTT drives a simple circuit to supply a keyed 12 VDC supply that is only on when it's safe from TX induced voltages, and can drive relays to detune towers and de-resonate wires when RX. Given that the K3S board has both a USB/serial chip and a sound card on it, no workable scheme proven robust for the K3 has to be discarded for the K3S. All that aside, glad you you managed to cage the snarling dog, by whatever means. :>) 73, Guy K2AV On Thursday, January 12, 2017, John Stengrevics wrote: > Three turns of the USB cable through a #43 ferrite and I am good to go at > full power (95 watts). > > John > WA1EAZ > > > On Jan 12, 2017, at 2:40 PM, Edward R Cole > wrote: > > > > Now that the thread has morphed to RFI: > > > > I was getting complaints from my wife that my transmissions were getting > into the home theater audio when she was watching TV.

Message-ID: Hi everybody, Thanks to Vic 4X6GP for the tips. I asked earlier today to Elecraft support to have an update on if we would like to use already own antenna coupler for those who already own an Elecraft W2. There is the information I received from Elecraft support : [ELECRAFT] If the W2 has been bought later half of 2016, it should be OK. If it is older than that, he will need to either get new couplers or Remove and Replace several surface mount components. And the modification to use older antenna couplers version consist of the following modifications: [ELECRAFT] You'll need to change C5 ,C6 and C7 to the updated value 470 pF I will need to modify both couplers that I have. The 8 pole relay is an excellent idea. And to change from coupler 1 to coupler 2, I am planning to use the AUX from the K-Pod.

Several years ago I had things working with a Navigator interface and my 756 Pro II, but it got fried by a lightening strike and I?m just now trying to get things working again. Here?s my setup: Full K-Line (K3) MicroHam MicroKeyer II Heil ProSet Plus (non-ic version) DXLab software (but I?ve tried FLDigi and several other programs as well with the same results) Symptoms: CW transmit and receive works well, both from the key and the software On other digital modes and voice, transmitter keys properly, but no power is transmitted The signal is making it out of the MicroKeyer interface (I plugged the cable that normally plugs into the Line In on the K3 into speakers and could hear the signal coming from the computer and interface) The signal is making it into the K3 (By enabling the MON, I was able to hear the signal through my headphones attached to the K3) Using the K3 utility, I can transmit in CW, RTTY and PSK I think this narrows things down to settings on the K3. The question remains, why am I not getting any output. Here are some relevant settings: Menu: MIC SEL: LINE IN Config: PTT-KEY: RTS-OFF (I?ve tried all settings) Mic Gain: 10 (I?ve tried increasing this with no change) I?ve also tried increasing the TX Level on the MicroKeyer with no change I?ve tried playing around with these settings but the results are still the same; power out with CW (but that is not coming through the Line In connection because I can disconnect it and I still have CW power), but no output on any other mode (unless I?m using the K3 Utility program, where I can get output on CW, RTTY, and PSK?but again, it is not through the Line In connection because it can be disconnected).

You must have 4 bars solid on the K3 ALC meter with the 5th bar flashing - this is the NO ALC point for the K3, ignore the internet advice which applies to non-Elecraft transceivers. The fact that you can hear the signal says it is getting to the K3, but says nothing about the level. Adjust the soundcard slider in your computer to about 75%. Make certain the Navigator is set for Line Level output and not MIC level. Then you should be able to adjust the K3 MIC Gain (really Line In gain) to achieve the required number of ALC bars. You can do that setup in TX TEST so you are not generating RF, or connect the K3 to a dummy load. Once you achieve the proper audio level, set your desired power level with the POWER knob. 73, Don W3FPR On 1/14/2017 9:00 AM, Bruce Miller wrote: > I?ve been working in vain over the past few days to get my K3 up and running digital modes (other than CW).

If it is an "iC" type, you need to turn bias on. If there is a capacitor in series with the AF line in the MicroKeyer, then setting bias on in the K3 will not be effective because the capacitor will block the bias voltage. Joe Subich can tell you about that. 73, Don W3FPR On 1/14/2017 11:30 AM, Bruce Miller wrote: > Thank you to both Ross and Don for your suggestions.

One nice thing on the K3 or K3S is that you can plug the two 3.5mm plugs directly into the back of the rig- no adapters needed, and no cables hanging out the front of the radio. However, my advice to anyone is that the most important thing to look for in a headset is COMFORT. The audio coming and going can be tailored to your liking for nearly any mic and headset using the equalizer in the K3, but if you can't comfortably wear it, even the most expensive headset is useless.

By Monday night there was another 20" on snow on the ground. It was also bending many of my trees almost to the ground. That night a number of trees exploded under the weight; twenty foot sections of their trunks turning into shrapnel. Branches breaking under the load of snow and ice also kept me awake. The next morning I found both of my doublets broken. The 14 ga THHN had parted in the middle where a branch had gone through it. Currently each of the three guy lines is under an inch or two of ice. Hopefully the coming thaw will let me repair them. One interesting note: the broken trees failed from their compressed side toward the side under tension. Now for the net options: you can appoint a temporary NCS and carry on or we can postpone the nets until I can repair the antennas. This should be by next Sunday. Since each doublet failed in the middle of a leg the repair will be easy once I can free the guy lines. 73 & Stay Warm, Kevin.

As an aside, I would also strongly recommend not using the default time sources that are recommended by Windows - the most reliable ones out there are 0.pool.ntp.org and 1.pool.ntp.org - the NTP pool provided there will remove a server that drifts by even a microsecond. Microsoft even advises not using their time servers for time-critical applications. At a previous job I worked in a data centre. Our server OSs used the basic Windows NTP client, syncing with our own time server (which had multiple sync sources itself), and despite only syncing once a week, none of the database servers or webservers ever drifted even a second per week. If your system is drifting that much, something is wrong and needs fixing. Start with looking at replacing your CMOS battery. 73, and a firm left handshake, John (XLX) -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Gordon LaPoint Sent: 15 January 2017 14:08 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3s-wsjt-wspr The windows time sync is not good enough to use for the jt or wspr timing, it only updates once a week.

The clocks on many system boards are very poor time keepers. JT65, JT9, WSPR and several more modes depend on the computer clock being exact, so why take a chance on the time, just use a *RELIABLE* ntp client. Data centers usually have much more expensive hardware that the average home cpu. Microsoft has had a very poor reputation with its time keeping for several decades now, for the average home cpu and software. Please remember that your experience with windows may not be the same as other all others here, that is why I offer an alternitive for ntp that is KNOWN to work much better. I have enough other problems in life than to worry about why MS cannot keep my clock on time, so I fixed it, with a real ntp client. Please don't assume that everyone has expensive modern hardware. thank you, Gordon - N1MGO On 1/15/2017 9:28 AM, John wrote: > Gordon, > > One thing to note here: if your computer's real time clock is losing more > than a second per week then something is seriously wrong with it! > > As an aside, I would also strongly recommend not using the default time > sources that are recommended by Windows - the most reliable ones out there > are 0.pool.ntp.org and 1.pool.ntp.org - the NTP pool provided there will > remove a server that drifts by even a microsecond.

Message-ID: Good afternoon all, I was operating in the NAQP CW this weekend and the main reason I purchased the K-pod was for contesting. It was great to have the VFO right beside my keyboard and to have the advantage of sending contest macros from the K-pod meant less mouse work. The question I have is...I did notice on many occasions when pressing the "F" buttons to send a macro (e.g. VE3WDM and Mike ON or K3 functions such as spot or A/B ) the macro did not send. Sometimes it took pressing the "F" button 3 times. Other times it was first press and I noticed this on all the F buttons I was using which was F1,2 4 and 8. Has anyone else had this? My question to Elecraft (as I know they monitor the list) is....is there an issue with my new K-pod? It is very frustrating during a contest to send your call and have it not happen or your exchange and nothing and as said sometimes up to 3 tries. As well to want to spot a station and nothing happens or A/B and nothing happens.

It does not change the normal operation of the K3, but does allow different levels of attenuation for the K3S - it is a per band setting. 73, Don W3FPR On 1/15/2017 4:43 PM, CenturyLink Customer wrote: > I recently was setting up my K-3 for interface with WSJT-X software.

Is this feature available yet, or imminent? I discovered that the P3 is pretty useful for unassisted search and pounce in last weekend's RTTY contest - While working one station on VFO-A, I'd move marker A up to the 'mark' tone of the next RTTY signal up the band. As soon as the QSO was logged, a tap on the P3 knob would jump to the next station to work. Then move Marker A again and repeat.

In-Reply-To: References: Message-ID: I saw a similar problem. Only tapping a button appeared to send the command to the K3 but the K3 failed to respond. For example, I had my K-Pod set up to use a tap of F5 to invoke M1, where my call was stored. Tapping F5 would result in "MSG 1" showing up in the VFO B space on the display but M1 was not activated. (Tony G6GLP) has also reported this problem. Tapping M1 on the K3 works every time. A few words about configuration before the inevitable queries are made. I have previously expressed my unhappiness with the length and stiffness of the supplied interface cable. IMHO, it's almost pointless to have a K-Pod if you can't locate it further from the radio. I also questioned the warning against having anything connected to Pin 1 on the radio end. It was suggested to me by an Elecraft engineer friend that I might use the existing cable as a "Pin 1 breaker" and then extend the cable using a female-female RJ12 connector and a standard RJ12 cable. So that's the setup. My K3S has the power mod installed but it's on sabbatical so I've been using my spare K3, which is unmodified. Hence I powered the K-Pod with a dedicated 12V power supply. The Pin 1 problem was previously described as a concern with having a wire hooked to a pin on a PIC, which could be upset by noise on the wire. It's looking to me like having any external wires connected to the PIC without buffering and/or decoupling is a bad idea.

It wasn?t a big deal, but any delay in a contest exchange is noticeable. As to the thought that the problem might be RF in the shack, that seems unlikely since the mis-press or whatever it is occurs before the XMTR is keyed when the tap is meant to activate a memory message. Could it be that the buttons have some free play in their holdings such that pressing one asymmetrically can result in a lesser contact, or is that mechanically not possible?

This cable has short transmission distance because of noise limiting the transmission of high numbers of bits per second. But in our case here, strong RF field is involved when transmitting, so the distance could be much shorter than 15m to avoid data corruption. I would strongly suggest to try using a cable made with shielded CAT6 cable, not standard ribbon cable usually used for phone,etc. Adding a few clip-on ferrite at both ends with as much turns you can could be a great addition too avoid misleading with unwanted noise in the communication line and ground path. Hope this help.

In-Reply-To: References: Message-ID: When you put the KPA500 into transmit there is some fixed (FET) drain current regardless of whether you are driving the PA or not. Likewise, the power supply is supplying this current. So the efficiency is zero and all of this DC power is converted to heat, not RF. Efficiency increases with drive. So what you are doing is poor practice. Furthermore, IMD performance of the driver (K3) is likely better at higher power. It's for sure better at 20W than 10W.

If you decide to try a longer ribbon cable first and are not interested in making your own, buy an RJ45 cable and F-F coupler to extend the Elecraft cable. Be sure to put the Elecraft cable closest to the K3, since it does not have pin 1 connected, and use the RJ45 cable for the rest of the run. Let me repeat my earlier comment: Macros 1 through 8 are accessed by HOLDING the KPOD switches for more than 1/2 second. Tapping (holding for less than 1/2 second) accesses K3 Macros 9 though 16. That might be what some of the people experiencing "unreliable" switch behavior are doing and not getting the reaction they expect from macros 1 through 8. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of NOEL POULIN Sent: Monday, January 16, 2017 6:52 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] k-pod data cable Hello, Anybody in this group, using a different length data cable supplied with the k-pod??The cable uses two 6P6C modular male connectors, and requires 5 conductors..

That works, but of course after each 'jump', VFO-B is at the frequency of the previous QSO. That means a little extra excursion to tune VFO-B past the current VFO-A frequency to get to the next one up the band. No big deal, just not quite as nice as using the markers on the P3. Anyhow, thanks for the tip. In hindsight it's pretty obvious, but I wouldn't have thought of it without your suggestion. 73 de W0ZF On Sun, Jan 15, 2017 at 10:35 PM Dave Fugleberg wrote: > Thanks Fred, I hadn't thought about that but it might be a workable way to > accomplish the same thing.

Ribbon cable is TERRIBLE for RFI susceptibility. Twisted pair is FAR superior IF each signals is on a pair. CAT5/6 is four tightly twisted pairs, 100 ohm impedance, each a different twist ratio to minimize crosstalk. I don't know anything about how the K-Pod uses that cable. For RFI, twisting is more important than shielding. 73, Jim K9YC On Mon,1/16/2017 8:23 AM, Ron D'Eau Claire wrote: > If you decide to try a > longer ribbon cable first and are not interested in making your own, buy an > RJ45 cable and F-F coupler to extend the Elecraft cable.

It's for sure better at 20W than 10W. Actually, the reason IMD performance is worse at 10W than at 20W is that at 10W you're still in the 10W section of the radio, while at 20W you're using the 100W amp. Once you're into the 100W amp, IMD performance degrades with increasing power. The K3 is capable of 120W, but since IMD increases rapidly above 100W, output is limited to 110W in firmware. As I see it, IMD is most important when a radio is driving a power amp, and most modern amps will get to rated power with about 50W. The KPA500 needs 25-30W drive. As indicated by measured CW keying bandwidth, the K3 is a VERY clean radio below 60W. IMD performance also degrades with reduced DC supply voltage. As I understand it, 13.8V is the nominal design voltage, and 15V is max rated. As to the original query about temperature -- Wes is exactly right about low power and efficiency. I do little or no ragchewing and mostly operate CW and SSB, but I do run RTTY for contesting and some digital modes that run keydown for about 50 sec and repeat every minute. When I do that on 6M, where the amp has the lowest efficiency, the fan will get pretty loud before the end of each TX cycle. That can be reduced a bit by setting the idle fan speed higher. It's a menu setting. 73, Jim K9YC From garysch69 at gmail.com Mon Jan 16 13:21:37 2017 From: garysch69 at gmail.com (Gary Schwartz) Date: Mon, 16 Jan 2017 18:21:37 +0000 Subject: [Elecraft] K3s remote line input gain setting Message-ID: Can anyone tell me the command to remotely set the Line Input gain. I know that the rig first has to be placed in the Line Input mode, which I can do remotely. But, the Line In Gain is distinctly separate from the Mic Gain. There is a remote command that sets the Mic Gain correctly, but there is no command I can find to set the Line In gain when in Line mode from a remote site. To be perfectly clear, the rig works correctly using the real front panel controls. If you select Line In, then the Mic Gain becomes the Line In Gain. When you change to a Mic input, changing the front panel Mic Gain has no effect on the line input level, i.e., the radio remembers the separate Line In gain setting. This is certainly easy to verify. Further, using the Elecraft Utility in Debug Mode, different codes are sent by the front panel Mic /Speed knob depending on whether you are in Mic or Line input mode. If there is a command, it is apparently undocumented unless one of you out there happens to know it. Thanks.

An RJ12 cable uses 6P6C connectors and connects all six wires in the cable pin to pin. That is, the RJ12 spec defines the complete cable and wiring, not just the connectors. So what Elecraft supplies with the KPOD is NOT an RJ12 since pin 1 is disconnected. That is important for anyone who goes out to buy a ready-made cable for use with the KPOD. I don't know of any standard cable configuration that disconnects pin 1 in a six wire cable using 6P6C connectors. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wes Stewart Sent: Monday, January 16, 2017 10:03 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] k-pod data cable 1) Let's get it straight that the connector is RJ12, not RJ45.

That works, but of course after each 'jump', VFO-B is at the frequency of the previous QSO. That means a little extra excursion to tune VFO-B past the current VFO-A frequency to get to the next one up the band. No big deal, just not quite as nice as using the markers on the P3. Anyhow, thanks for the tip. In hindsight it's pretty obvious, but I wouldn't have thought of it without your suggestion. 73 de W0ZF On Sun, Jan 15, 2017 at 10:35 PM Dave Fugleberg > wrote: Thanks Fred, I hadn't thought about that but it might be a workable way to accomplish the same thing.

Is this feature available yet, or imminent? I discovered that the P3 is pretty useful for unassisted search and pounce in last weekend's RTTY contest - While working one station on VFO-A, I'd move marker A up to the 'mark' tone of the next RTTY signal up the band. As soon as the QSO was logged, a tap on the P3 knob would jump to the next station to work. Then move Marker A again and repeat. With a little practice, and the SPAN set fairly narrow, I could nail the tuning every time, provided I didn't bump the P3 knob when tapping it. Although that worked well, it was a lot of reaching to the P3. It would be a BIG improvement if a K-Pod, right next to the keyboard, could control those functions. Can it? 73 DE W0ZF ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to fcady at montana.edu From lists at subich.com Mon Jan 16 17:20:27 2017 From: lists at subich.com (Joe Subich, W4TV) Date: Mon, 16 Jan 2017 17:20:27 -0500 Subject: [Elecraft] K-Pod question In-Reply-To: References: Message-ID: <5894d2ed-a186-e78c-e49b-d6d8c53ded47@subich.com> On 1/16/2017 11:44 AM, Dave Fugleberg wrote: > I experimented a bit with the method suggested by Fred, using VFO-B > to 'mark' the next signal up the band, and then using A/B to 'jump' > to it.

When I said. "As I've written before", what I had said earlier was: "I saw a similar problem. Only tapping a button appeared to send the command to the K3 but the K3 failed to respond. For example, I had my K-Pod set up to use a tap of F5 to invoke M1, where my call was stored. Tapping F5 would result in "MSG 1" showing up in the VFO B space on the display but M1 was not activated. (Tony G6GLP) has also reported this problem. Tapping M1 on the K3 works every time." Read the last sentence. Additionally, there are other messages in Bank 2 so something should have been sent. But this thread and others---IMHO of course---exposes a missed opportunity. Instead of this Mickey Mouse way of writing a limited number of macros, that have to be sent to the K3 and stored, only to be executed by a K-Pod over a dubious interface, the macros should simply be saved in the K-Pod in the first place and sent via USB and/or RS232.

I use it to connect the real-time clock board to my BeagleBone Black board. I2C is a 2 way, multi-master bus protocol that might be ideal for tying the ever-growing collection of Elecraft devices. We would really like to send commands from whatever device we're using, whether it is the controls of the K3, a keyboard attached to a P3, the panel of a KPA500, or the K-Pod.

I suspect some of the JST related software etc... might force a sync at startup and or do NTP server syncs on their own? Someone else will need to chime in on that. The best time sync you are going to get for Windows and Linux / BSD based operating systems will be us use the full on NTP client. For windows, Meinberg has a nice graphical client that installs and sets itself up as a service and disables the windows NTP client service. During the Meinberg NTP install, you have an option to draw from the NTP pool of NTP servers and you can also type in your own preferred NTP server list. The full NTP client does more than just sync your clock... over time it will calculate the drift of your clock and discipline your clock automatically between sync checks to your selected NTP servers. The drift is calculated in PPM and for the curious you can see how bad your clock is. Here is the link for the Win32 install of the Meinberg client (free): https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable I run 3 GPS disciplined NTP servers (3 separate GPS receivers) here at my QTH and if you want, you are welcome to use time.nc7j.com as one of your NTP servers. On this end, time.nc7j.com is accurate into the nano second range as compared to the GPS on board atomic clocks. Via NTP UDP sync over the Internet, the best you will typically do is get down into the lower microsecond range... and far more accurate than any thing most would ever need. time.nc7j.com is also a member of the NTP pool and you can see if it's up and running be going to this link: http://www.pool.ntp.org/scores/time.nc7j.com The chart here doesn't show the accuracy of the time.nc7j.com, but it shows the ping offset from LA to Utah and it's normal to vary +- 10ms. Your mileage will vary with your round trip ping times to any NTP server, but over time, NTP will do an amazing job of figuring out your PC clock drift and then disciplining it on the fly. For the totally 'time accuracy obsessed', you can install the Meinberg NTP monitor too and monitor your clock accuracy via logged NTP statistics: https://www.meinbergglobal.com/english/sw/ntp-server-monitor.htm#download The Meinberg apps are GUI's that make native calls to the full NTP install under the covers and they are totally free and free of any nag related nonsense. If you are running Linux or iOS, you are already running a native NTP client I suspect and you can read up on how to configure it just like the Meinberg Windows GUI's do for Windows.

I think you are correct about the I2C electrical connection, but I still think Elecraft needs a box to box communication protocol which allows multi-masters. USB would do, but probably isn't the only choice. Ethernet? There is a question of just how much distance needs to be supported. If you have your KPA500 at the base of your antenna, that is quite a distance, on the other hand, you probably don't need to control you K3 from there. 73 Bill AE6JV On 1/16/17 at 8:23 PM, wes_n7ws at triconet.org (Wes Stewart) wrote: >Bill, > >I dunno.

It turned out it was the PC com port power saving setting. It caused a 5 seconds delay while it woke it up! Good luck with getting it solved, I have been a Mac user since they came out, but in the end decided that for the radio I was better off getting a Windows PC, and I leave my Macs for everything else, photography, programming, internet and so on. But let's not get into a Mac v PC discussion as we know where that leads to. 73 from David GM4JJJ > On 17 Jan 2017, at 12:11, John Stengrevics wrote: > > Max, > > Thanks for the reply.

"CAN Bus" (Controller Area Network) would do the job. Either a single (screened) twisted pair (differential signalling, highly resistant to external EMI) or two pairs. Its extensively use in vehicles, industry and many places where there is lots of electrical QRM. Serial data rates can be high (many 10's of kBaud) and nodes are addressable. No need to invent yet another bus. 73. Dave G0WBX.

The beauty of simple clean lines is one of the things that drew me to the K-Line in the first place (and probably why I keep buying all the matching pieces).

If the K2 was built quite recently (or has had the encoder changed to the new one), then the K3 knob(s) will fit. I would suggest the K3 VFO B knob for those newer K2s - the VFO A knob is too large and its diameter interferes with the display plastic. You would have to add substantial thickness to the felt washer to provide a bit of drag on the knob. Know that the K2 knob is weighted, but its weight is not as heavy as the CNC knobs that have been offered. My gut feeling is that one reason that those heavy knobs are used is to allow giving the knob a spin to make large QSY excursions. The problem with that is with a free-spinning knob, the knob may move after it is stopped, so the frequency you thought you stopped at will be changed when you lift your fingers from the knob. I have had several K2s sent to me for repair that had no drag on the knob, and part of the reason for sending the K2 for repair was that "the K2 drifts". There must be some drag on the knob if this "drift" is to be avoided. Lastly, if you install a heavy knob and then ship your radio for any reason, you should remove the knob to assure that the encoder shaft will not be damaged during shipment. 73, Don W3FPR On 1/17/2017 6:11 PM, Niel Skousen wrote: > Has anyone used the K3s knob on a K2 ? > > Does it fit, how do you like it ?? > From lroux1 at att.net Tue Jan 17 19:16:09 2017 From: lroux1 at att.net (Lou Roux) Date: Tue, 17 Jan 2017 16:16:09 -0800 Subject: [Elecraft] For Sale Elecraft K1-4 Message-ID: <993875ad-9fe7-c9b3-8c10-22a181776864@att.net> I have for sale the above radio.

Surely personal but I liked the change in rotational feel. Subtle but there. Worth the money I'd say no but the deed was done. Along came the model with the aluminum inserts and dimple with a bearing. They so reminded me of the Collins gear I wished for and the Heath SB series I had way, back then that I got a set. Liked them and got a K2 matching knob from his limited run of that. Along comes the KPOD.... Knob didn't match. No response from 73CNC. Did a WTB on the reflector and secured another. As a retired engineer sometimes "eye candy" wins over function. A Ferrari or Chevy will both get me to the store for a quart of milk but...... My KX3 feels neglected. Wants verses needs are totally different. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 1/17/2017 1:36 PM, Wayne Burdick wrote: > Both the stock VFO A knob and VFO B knob are weighted.

First, you may be better off using DATA A submode rather than USB because the compression is automatically set to zero and the TX EQ is set flat. That allows you to set your SSB compression and TX EQ as you wish for voice modes. Like all other K3 DATA modes (driven by whatever applications), you must drive the audio as indicated in the K3 manual. You should have 4 bars illuminated on the ALC meter with the 5ht bar flashing. Set the computer soundcard speaker slider to about 75%, and plug the soundcard output into LINE IN on the back of the K3. With the K3 set to DATA A mode, set the K3 MIC SEL to LINE. You can do the following adjustments in TX TEST mode so you do not produce RF. Then do a Transmit from the computer application and adjust the K3 MIC GAIN (now LINE IN gain) to produce 4 bars solid with the 5th bar flashing on the ALC meter. Adjust the power level desired with the POWER knob. Ignore the advice for other transceivers which tell you to set the power for maximum and use the audio level to control the power output - the K3 is different, and the use of that "advice" will produce exactly the situation you describe. 73, Don W3FPR On 1/17/2017 7:56 PM, Jerry wrote: > Hello, > > > > I am using my K3, KAT500 and KPA500 in an MARS environment and I am having > this problem.

I've had it for about 3 Years. ?I rarely tune the radio with the know using mostly software. However now a days when I do turn the knob there is a very pronounced dead spot, and a notch in the turning of the knob. The weight of the knob has permanently altered the feel of the encoder and I fear it will need to be replaced one day.Because of this, ?I do not recommend weighted knows on a k3. Perhaps if you use it every day it would be different. But if you mostly just let it sit ?my experience is that it will permanently damage the encoder over time.73 Tom?va2fsq.com?

If the K2 was built quite recently (or has had the encoder changed to the new one), then the K3 knob(s) will fit. I would suggest the K3 VFO B knob for those newer K2s - the VFO A knob is too large and its diameter interferes with the display plastic.? You would have to add substantial thickness to the felt washer to provide a bit of drag on the knob. Know that the K2 knob is weighted, but its weight is not as heavy as the CNC knobs that have been offered. My gut feeling is that one reason that those heavy knobs are used is to allow giving the knob a spin to make large QSY excursions.? The problem with that is with a free-spinning knob, the knob may move after it is stopped, so the frequency you thought you stopped at will be changed when you lift your fingers from the knob.? I have had several K2s sent to me for repair that had no drag on the knob, and part of the reason for sending the K2 for repair was that "the K2 drifts". There must be some drag on the knob if this "drift" is to be avoided. Lastly, if you install a heavy knob and then ship your radio for any reason, you should remove the knob to assure that the encoder shaft will not be damaged during shipment. 73, Don W3FPR On 1/17/2017 6:11 PM, Niel Skousen wrote: > Has anyone used the K3s knob on a K2 ? > > Does it fit, how do you like it ?? > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to tomb18 at videotron.ca From edauer at law.du.edu Tue Jan 17 23:21:12 2017 From: edauer at law.du.edu (Dauer, Edward) Date: Wed, 18 Jan 2017 04:21:12 +0000 Subject: [Elecraft] Weighted knobs Message-ID: <96E77C36-7370-4C65-A289-E72FAF1B6AA2@law.du.edu> I bought the neoprene ring for the K3 VFO A knob and am glad that I did. Now it, and the K-Pod knob, are just about perfect for my touch. I bought two after-market weighted knobs with ball bearing dimples for my K2s, and I am also glad I did that. To my taste the stock K2 knob is a bit too light, albeit aesthetically superior to the bulkier after-market replacements. The overshooting that Don Wilhelm mentioned is indeed a problem with the heavier K2 knobs, but with some home-made fuzzy washers and a bit of time adjusting the spacing on the encoder shaft, it is possible to balance the stability with the spinability. Was it worth nearly a hundred bucks a knob to do the K2 replacements? Maybe not. But I agree with Guy (K2AV) -- after a certain point in life, one has earned the license to be unsatisfied with anything that isn?t exactly what you want. Harrumph.

Just to explain further, on meteorscatter it is possible for many stations to share the same frequency, as bursts are short and one station may not hear the same burst as another if they are in a slightly different location. We use conventions for which transmit period to use based on where we are beaming in one of the 4 quadrants. For example if beaming East or South we transmit on the second period so start at 15 secs after the top of the minute. This allows a couple of locals to both call CQ or work another station on the same frequency without hearing each other, but they are both able to hear and respond to any callers. If their clocks are a second or more out then there will be a slight overlap and the locals will interfere with each other for that short overlap time period. There will have to be a slight delay for relays and sequencers of course. There is a 200 ms software TX Delay between PTT being asserted and data sending in WSJT-X by default to allow relays to settle, though a hardware sequencer is a safer solution. All of the above is covered in the online documentation for WSJT-X http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-1.7.1-devel.html#SYSREQ 73 from David GM4JJJ > On 17 Jan 2017, at 18:02, Nr4c wrote: > > Mine only transmits for around 42 seconds.

I have synched my Mac to time.nist.gov and the time.is site shows that I am dead on. If anyone has any suggestions, they would be much appreciated. The Mac can be quite difficult to keep accurately time syncd using NTP, as it doesn?t always check the time from the best server and many other little snags like not checking very often sometimes. If you have a reasonably modern version of the Mac OS then add some other NTP servers for your region to the Date & Time preferences, after the standard Apple one, separated by a comma. For example just add: 1.pool.ntp.org, 2.pool.ntp.org after whatever Apple has chosen. In Europe I use time.euro.apple.com, 1.uk.pool.ntp.org, 2.uk.pool.ntp.org Please use your own region's ntp pool Uncheck "Set date and time automatically" and recheck it, it should update it. Open a terminal window and type ntpq -p You will get a list of the servers and their offsets (in ms) as well as other nerdy stuff. You will notice that NTP slowly drift corrects the clock. It only polls slowly so you have to be patient, but the good thing is it should learn.

Both are selected using the PRE switch. The KX2 is an SDR, and typically such rigs have about -120 dBm MDS with preamp off, and -135 dBm with preamp on. This can make a huge difference on a quiet band. The dynamic range is good enough that you can probably leave the preamp on all or most of the time. Let me know if your received signals are still down after turning on the preamp. If that doesn't fix it, you could have APF turned on (very narrow audio peaking filter), or NR turned on (noise reduction), or you could have a problem with a bandpass filter, etc. 73, Wayne N6KR On Jan 18, 2017, at 8:32 AM, Paul Smith wrote: > I have a KX2 nr 855 I bought in August.This is my first venture in in a sophisticated radio.

Note that there are two trimmer capacitors on the K60XV board for exactly that purpose. These additional capacitors are switched in so the bandpass filter can be peaked on 60 meters. The cutoff for the 40 meter Low Pass filter is well below the 2nd harmonic of 60 meters, and can be used on 60 meters without signal attenuation. In other words, the K2 on 60 meters has the same RX sensitivity as the other bands. 73, Don W3FPR On 1/18/2017 3:13 PM, Heinz Baertschi wrote: > Based on the fact that the K2 has 5 BPF and LPF only to cover 9 bands I > wonder > > 1) if/to what extent the RX performance on the existing bands is influenced > by the addition of the 60m band (K60XV)? > > 2) what RX performance can be expected on 60m (compared to the K2 standard > bands)?

Are you working CW or SSB? 3564 is CW and your filter should be like .25, .30 or whatever you set it at in CW mode. A filter BW of 2.80 is an SSB filter BW. Do you have your KX2 in the wrong mode or some split mode? (I.e., TX on one VFO, RX on another?) What mode are you trying to work? > I am ocnfused what to do and or to look for. I could hear checkins on my > Tribander and not a peep heard on the KX2 My KX2 is more than sufficiently sensitive and yours should be too with 100' of wire in the air. Most signals are quite clear and distinct with the audio set 8-12, and higher than that only for very weak signals. So check that you are in the right mode, ensure RIT and XIT are turned off (for no offsets), and RX and TX both on VFO-A, then tune around and you should hear signals. If not, let us know. I've only used the KX2 on CW, but I've never seen the PREamp change to something else on its own without hitting the PRE button. It should be in PRE mode for most work.

It goes like this: Normally nothing is wrong. Nor in ATU AUTO mode nor in ATU CALS mode. But sometimes after using the KAT2 auto-tuner (setting ATU AUTO) there's no RF signal on the ANT1/ANT2 sockets and the SWR reading is infinite. Yes, when I check on the original "Antenna 50 Ohm"-socket there IS signal but nothing comes out of the ANT1 (or -in case selected- ANT2) socket. In some cases I'm able to recover the normal desirable behavour bij disconnecting the KAT2 unit from the RF-board and reconnect. There really are times there's nothing wrong with the ATU and I'm able to tune different loads on different bands. But all of the sudden the error kicks in again. When the error has happened I can get an error-code from the KAT2 settings menu. Normally (when error-free operating) the error code is E000 In case of error it gives E216 or E232, depending on whether de ATU is in mode AUTO or CALS.

Use DATA A Set the audio input to the KX3 so you have 4 bars solid on the ALC meter with the 5th bar flashing. Once you have the audio level set, leave it that way. Control the power output with the POWER knob. Ignore the advice in the JTx information and on the internet to control the power with the audio level - that is for non-Elecraft transceivers. Any differences in the various soundcard data modes will be found in the software application used, not in the KX3 setup. 73, Don W3FPR On 1/19/2017 8:20 AM, James Rodenkirch wrote: > Anyone operating JT(?

You may have to resort to measuring the RF voltages as indicated in Appendix E of the manual - Transmit Signal Tracing to find where the failure might be. Check the value of R98 on the bottom of the RF board. The fact that the maximum power drops off significantly on the higher bands tells me that the value of R98 could be greater than the stock value of 270 ohms. What happens to the voltage at RF Board U9 pin 3 when you do a TUNE? It should drop to 1/2 the value that it has during receive. If not, Q20 is not working properly. For your 160 meter problem - is C153 68pF? Also is C68 10pF (if you have an older K2, it may be 4.7pF. On the irregular behavior of the POWER knob, it could be a worn pot - look at the power displayed as you turn the knob - it should be smooth. If it is, my suspicion lies with the value of R98. Remember that the VALC voltage is what actually controls the drive to the TX Mixer, and the value of R98 is a controlling factor in the power control loop damping. If this K2 had the KPA100 installed and the power output went up and down during transmission, the fix is to increase the value of R98 - some builders went too far with the increase resulting in low power on the higher bands and possibly 160 meters. 73, Don W3FPR On 1/19/2017 10:55 AM, Byron Allen wrote: > Don, > > I have now done more tests and bandpass filter alignments....Don, > As you suggested I checked all the voltages in the Elecraft manual on the > RF board.

There were some good suggestions made here and I?ve checked them all and I?m unable to get the K3S to chirp. So, at present: unable to replicate.. Some of the suggested things I?ve checked: 1) SWR at the K3S while driving the ACOM 1500 (same operating conditions) is 1.05 to 1. SWR between the ACOM and the antenna at the noted frequency is 1.2 to 1. 2) Voltage at the K3S is 13.8 key up and 13.2 key down; seems OK. Power supply is a switcher which I?ve used for some years. 3) K3S is drawing 21.96 amps key down. (Not running 100 watts into the amp.) 4) I?ve intentionally ?mis-tuned? the amp just in case that is what was going on when the OO noticed the chirp. I did this by tuning up properly at 14.001 and then QSYing to 14.083 and transmitting while monitoring with a different receiver. No chirp, clicks or other anomalies. This is a much worse operating condition than I normally encounter. It?s so easy to tune the ACOM that I keep it properly tweaked. Also, I was operating in CW SS and in the middle of a 2 hour run when the OO heard me chirping and I have a tough time imagining that I?d sit on a given frequency for two hours without making sure I was properly tuned. 5) I do not use ALC between the K3S and the ACOM. I do run with specific power levels on each band (great feature, BTW) such that I?m not able to overdrive the amp. 6) I?ve checked my in-the-shack coax jumper cables and I don?t see any issues. The antenna end of the coax is currently under 2 feet of snow so I haven?t looked at it. But, I?m getting normal SWR readings here in the shack. There isn?t any arcing going on or the amp would shut down. No RF in the shack; no TVI or other issues in the house. 7) I recently made 535 QSO?s in NAQP CW and did quite a bit of listening on a second receiver, never heard a chirp. I wasn?t using the ACOM so I ran the K3S at 100 watts. And, finally, I have not yet received another OO report after the NAQP. ;-) I dunno what to think.

While that could conceivably be linked to change in the power bus voltage, it's highly unlikely since the bus is isolated from the actual synthesizer by voltage regulators and filters. OTOH, the OO's report was strictly advisory. I have experienced spurious OO reports over my >50 years of pounding brass, and one that turned out to be accurate when I blew the filter caps in the transmitter and did not notice, nor did the stations I was working report the hum on my signal. When I got a "chirp" report one time (on a homebrew rig) and was unable to hear it myself, I sent a friendly letter to the OO. He replied that he was "almost sure" he could detect a "slight chirp" so he sent the card. So my advice is that if you can't repeat what the OO observed, don't worry about it. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Doug Smith Sent: Thursday, January 19, 2017 11:09 AM To: Elecraft Reflector Subject: Re: [Elecraft] K3: past chirp report Yup, that was me. There were some good suggestions made here and I?ve checked them all and I?m unable to get the K3S to chirp. So, at present: unable to replicate.. Some of the suggested things I?ve checked: 1) SWR at the K3S while driving the ACOM 1500 (same operating conditions) is 1.05 to 1. SWR between the ACOM and the antenna at the noted frequency is 1.2 to 1. 2) Voltage at the K3S is 13.8 key up and 13.2 key down; seems OK. Power supply is a switcher which I?ve used for some years. 3) K3S is drawing 21.96 amps key down. (Not running 100 watts into the amp.) 4) I?ve intentionally ?mis-tuned? the amp just in case that is what was going on when the OO noticed the chirp. I did this by tuning up properly at 14.001 and then QSYing to 14.083 and transmitting while monitoring with a different receiver. No chirp, clicks or other anomalies. This is a much worse operating condition than I normally encounter. It?s so easy to tune the ACOM that I keep it properly tweaked. Also, I was operating in CW SS and in the middle of a 2 hour run when the OO heard me chirping and I have a tough time imagining that I?d sit on a given frequency for two hours without making sure I was properly tuned. 5) I do not use ALC between the K3S and the ACOM. I do run with specific power levels on each band (great feature, BTW) such that I?m not able to overdrive the amp. 6) I?ve checked my in-the-shack coax jumper cables and I don?t see any issues. The antenna end of the coax is currently under 2 feet of snow so I haven?t looked at it. But, I?m getting normal SWR readings here in the shack. There isn?t any arcing going on or the amp would shut down. No RF in the shack; no TVI or other issues in the house. 7) I recently made 535 QSO?s in NAQP CW and did quite a bit of listening on a second receiver, never heard a chirp. I wasn?t using the ACOM so I ran the K3S at 100 watts. And, finally, I have not yet received another OO report after the NAQP. ;-) I dunno what to think. The issue remains unresolved but I am unable to replicate the problem. 73, Doug, W7KF http://www.w7kf.com > On Jan 19, 2017, at 9:44 AM, Richard Fjeld wrote: > > A few weeks ago, someone had received a chirp report.

If they are measured outside the K3 with an accurate DVM, I would say they are marginal. If so, raise the key up voltage to 14.2V. If they are measured by the K3S' internal voltmeter they might be OK. 3) That's way high. My K3S draws no more than 17A at full 100W out. I can't really comment on the other bullets. I have heard other reports of K3 chirps that turn out to be nothing more than hearsay.

The synthesizer settles well before the rig switches from TX to RX or vice-versa. The KSYN3A (newer synth, used in the K3S) settles in well under 1 ms thanks to its entirely digital architecture (UHF DSPLL, divided down). The KSYN3 (older synth, used on the K3) uses a more traditional PLL with its VCO running at the target output frequency. It normally settles in under 5 ms. It can take a bit longer depending on the actual PLL voltage and VCO frequency. This is accounted for in firmware. If your KSYN3 were not properly calibrated, you might see a longer settling time on one or two bands, most likely 6 meters. If you suspect this, refer to the CONFIG:VCO MD menu entry. The K3 includes an automatic VCO calibration routine that requires no test equipment and takes only a couple of minutes to run.

I was under the impression that since the connection between the K3/P3 and the amp and the tuner are all 50 ohms, and there fore a 1:1 swr the amp would see a match of 1:1 and there would be no reduction in power due to the antenna mismatch.

I have selected a Palstar HF Auto. Why an automatic tuner? The amp has an auto-tuner, and the two are unlikely to play well together. Instead, I'd look at a good manual tuner like the Ten Tec 238. I've owned several of them and find them to be good performers. So did ARRL Labs when they tested them many years ago. Ten Tec has been sold a couple of times and new 238s are probably no longer available, but used 238s are usually available on the used market. Best bet are the B and C models, which have a vernier readout for the inductor, as opposed to a dial cord in the older models. Expect to pay about $400 for the B or C, $300-350 for the older units. The 229 is electrically and mechanically the same as the older 238s, but in a cabinet that matches older Ten Tec rigs. To use this tuner in your station, set the SPE to bypass mode, tune it for the bands where you operate and log the settings. Then put the SPE tuner back in line in auto mode and let the auto tuner do its thing to cover the band(s) as you QSY. 73, Jim K9YC From wgwetherill at gmail.com Thu Jan 19 17:37:30 2017 From: wgwetherill at gmail.com (Bill Wetherill) Date: Thu, 19 Jan 2017 17:37:30 -0500 Subject: [Elecraft] Elecraft KX3 Still For Sale Message-ID: Still For Sale: Elecraft KX3 (Excellent Condition) Antenna Tuner Roofing Filter KX3 Desk Stand KX3 End Panels KX3 Cover Construction and Operation Manuals Power Cord New Price Shipped to CONUS $1,000.00 Pics on request.

You connect the KXPA100 to the personal computer and the adapter cable splits out the RS-232 signalling to the KX3. See the connections on page 14 of the KXPA100 manual. The KX3USB cable connects between the KXPA100 and the PC. No MAGIC BOX needed. The PX3 does not have to be continuously connected to the computer. For firmware updates, Configuration Save and Restore, you can connect a KX3USB cable and run the PX3 Utility for those operations (those are done off-line and not real-time). 73, Don W3FPR On 1/19/2017 7:19 PM, David Orman wrote: > Hi, > > I'd like to have serial output via db9 and also usb at the same time with > my KX3.

It sounds like so much more, doesn't it? It sure makes us feel better to think that we're louder on the other end. But first, on your S-meter take a look at the width of one S-unit, which is commonly held to be 6 dB. Now imagine that single S-unit divided into six equal parts, each of them 1 dB. If you have an analog S-meter the needle is probably wider than one of these parts. Do you think you could hear a difference if a signal increased (or decreased) by one of these skinny little 1 dB increments? Well, the increase from 500 to 625 Watts is a little bit *less* than one of these increments. Furthermore, especially if you're on phone, the increase in in-band intermod that results from pushing any amp may actually subtract a little bit of intelligibility from your SSB signal. I don't know what the dB equivalent of this "intelligibility loss" would be... but what if it's like 0.5 dB? It's simply not worth it. If you ever want to calculate for yourself the dB change from an increase or decrease in power one place you can find the equations (as well as a link to an on-line calculator) is here: http://www.radio-electronics.com/info/formulae/decibels/decibel-formulae-equation.php . Someone will say, "But when your signal's right under the noise floor on 160 CW, that extra 0.9691 dB might help." I agree in advance-- to save you the trouble of having to point out that rare situation. For the rest of us, the conservatively rated output of the KPA500 should be just fine.

David, What is the external device? Does it need to poll the KX3 or is it satisfied by seeing the IF; and/or FA; responses to the logging software? RS-232 is a point to point protocol and does not allow for multiple active transmitters at the same time. However, in some cases one can attach a second "receive only" device in parallel. The typical connection is shown in the SteppIR "Y cable" schematic that I have sent to you directly (ignore the jumper between pins 7 and 9 as that is SteppIR specific). If both the computer and hardware device must poll independently, you might be able to get away with a "Modem Data Splitter" like one of these from B&B Electronics: http://www.bb-elec.com/Products/Serial-Connectivity/Serial-Data-Tools-Adapters/Port-Splitters.aspx> but you need to be careful that both the logger and hardware device do not send data to the KX3 at the same time since the modem data splitter is passive (diode isolation) and the data will be corrupted if both devices transmit at the same time. 73, ...

Message-ID: Wayne, Thanks for posting this! Since the KX2 is my first SDR, it never occurred to me to try the preamp on 80 meters. In fact I was very happy running with the preamp off, attenuator off, and RF gain set between about -3dB and -6dB. This morning I was listening to FK8DD, and found I could copy him much better with preamp on, and RF gain at -10 dB, attenuator still off.. BTW, I really like the AGC on the KX2, and often find myself trying to adjust my K3 so it sounds as good as the KX2. 73, Chuck Guenther NI0C Quote from N6KR: "First thing to check is to make sure the preamp is on, and the attenuator turned off. Both are selected using the PRE switch. The KX2 is an SDR, and typically such rigs have about -120 dBm MDS with preamp off, and -135 dBm with preamp on. This can make a huge difference on a quiet band. The dynamic range is good enough that you can probably leave the preamp on all or most of the time. Let me know if your received signals are still down after turning on the preamp. If that doesn't fix it, you could have APF turned on (very narrow audio peaking filter), or NR turned on (noise reduction), or you could have a problem with a bandpass filter, etc. 73, Wayne N6KR" From riese-k3djc at juno.com Fri Jan 20 11:40:46 2017 From: riese-k3djc at juno.com (riese-k3djc at juno.com) Date: Fri, 20 Jan 2017 11:40:46 -0500 Subject: [Elecraft] K3: past chirp report Message-ID: for all you churp cops,,, tune around during th antique radio contest,, no rig circuit made after 1929 is used,,,, i use a hartley osc which can cherp out of the k3 pasband if i pushit over 3 watts to the antenna,,, it begains to sound real good Bob K3DJC http://www.antiquewireless.org/awa-on-the-air.html On Fri, 20 Jan 2017 06:10:19 -0700 (MST) Barry writes: > Does the radio automatically go into chirp mode if it detects > operation from > Cuba? > Barry W2UP > > > > -- > View this message in context: > http://elecraft.365791.n2.nabble.com/K3-past-chirp-report-tp7625892p76259 20.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 at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to riese-k3djc at juno.com > From hlyingst at yahoo.com Fri Jan 20 11:54:55 2017 From: hlyingst at yahoo.com (Harry Yingst) Date: Fri, 20 Jan 2017 16:54:55 +0000 (UTC) Subject: [Elecraft] Any ideas on how to run serial (DB9) and USBserial at the same time?

Today we can fit a few more signals into the same band with absolutely clean rigs and keyers that make all signals sound the same - especially as more stations shift to keyboard CW that even removes slight differences in inter-character and inter-word spacing. Even so, it was nice tuning across the band and being able to say with confidence, "That's Al in San Diego" or "Ernie in Detroit" or "Arnie in Havana". Immediately we knew a lot about band conditions too without beacons and other "modern" aids. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Barry Sent: Friday, January 20, 2017 5:10 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3: past chirp report Does the radio automatically go into chirp mode if it detects operation from Cuba?

(In a vehicle with the engine running for example.) Unless specifically designed for such use, Switching PSU's are generally quite poor in regards to dynamic regulation (such as would be needed for QRO CW or SSB.) However, from what Wayne describes above, even if the incoming DC dips a little, I get the impression the DC rail for the synthesizer itself is likely to stay clean. But, while the SMPS is recovering from a sudden large load being applied, it could introduce a burst of noise on the PS lines, that might couple into other things causing trouble. Similar things also happen when the load (RF) is suddenly turned off, then though, you get a voltage spike, and maybe some "cycle skipping" in the PSU as it tries to prevent such... What make/model of PSU? I've yet to find one for the "Amateur" market that is anyway near half as good as the mega bucks SMPS cinder block sized things we use in the commercial multi kW QRO amps we handle at work. And even they have a few issues when the amp is carrying high levels of pulsed RF. And the types designed for telecom or "server" use, are often very much poorer in regards to dynamic regulation, especially if the RX current draw is a under 10 to 15% of their rated max load, as they would have been designed for a high power delivery, that does not vary much. 73.

Of note in this release is support for the new SDRPlay RSP2 in addition to the RSP1. The SDRPlay can be used with the K3 and the IF output as a Panadapter and with a transmit / receive switch, can also be used with the KX3 and KX2 providing a Panadapter display with a maximum span of 2MHz at very low cost. This release also has a new feature allowing Win4K3 to be used with hardware devices that only monitor Elecraft radios like antenna tuners, third party amps etc. Traditionally, one would need to make a serial port "Y" cable so that the devices could listen for frequency and band information. With Win4K3Suite all you need to do is plug your device into a free serial port on your system and then connect to it with Win4K3 telling it what information needs to be sent to the device. No need to fuss with cables. Win4K3Suite is the ultimate Elecraft control program supporting all hardware and seamless integration with many third party software and hardware products.

I find it is really helpful for contesting, particularly, and pile up busting where you are throwing your call out, and out, and out, etc. Pushing a button to send 599 TU cuts down on fatigue. It's another useful tool in the bag along with the spectrum display that can quickly show where there is activity, but most importantly, I can see where the DX station is working that other guy in a split operation; this works better than having a second receiver. 73, Barry K3NDM ------ Original Message ------ From: "Chester Alderman" To: "'Tom'" ; "'Elecraft'" Sent: 1/20/2017 4:59:14 PM Subject: Re: [Elecraft] New release of Win4K3Suite supporting the SDRPlay RSP2 >I've been a CW operator for a little more than 65 years, and I still >enjoy >it.

It does include a panadapter display for those who have the hardware to provide I/Q signals to a computer soundcard - that much is built-in and does not require additional software applications. The Win4K3 software provides "hooks" to be able to run additional applications that normally would want to use the communications link to the K3 themselves - normally only one application at a time. But Win4K3 allows the use of multiple applications that would normally want connection to the K3 "all to themselves", and that allows a lot more flexibility in your choice of various applications that want to communicate with the K3. It does not itself generate CW, but does provide the "hooks" for running software applications which you *may* want to add. The choice of applications is yours to make, and the justification for the cost of those applications is for your judgement only. There is nothing in the Win4K3 documentation that says you have to use any particular application - it simply states that "these applications are supported" by the Win4K3 software. 73, Don W3FPR On 1/20/2017 4:59 PM, Chester Alderman wrote: > I've been a CW operator for a little more than 65 years, and I still enjoy > it.

I was just corrected by Tom in that he says his program will interface with a keyboard, so I will have to look at it again?! The reason I am interested in keyboard generated CW is because I used to run QRQ in excess of 60 wpm (up to 120 wpm) and I didn't ever attempt to push a mechanical key to those speeds. While I still use the old YPlog for QRQ (it will work, no stutter, up to 200 wpm) and NO, I never got that high!). I also switched to a Dvorak layout keyboard to enable to get my typing speed from about 40 wpm max to around 140 wpm (brief spurts..hihi). 73, Tom - W4BQF -----Original Message----- From: Barry [mailto:k3ndm at comcast.net] Sent: Friday, January 20, 2017 6:59 PM To: Chester Alderman; 'Tom'; 'Elecraft' Subject: Re[2]: [Elecraft] New release of Win4K3Suite supporting the SDRPlay RSP2 Tom, I, too, have been at for a while, but I'm really happy to have the adjunct.

There is no need for additional software such as FLDIGI or anything if you do not want it. In fact it is much simpler since you do not need to work with a sound card.?Of course if you wish to use a third party product for cw or digital modes it works with them also.One questions is the speed of the CW. Win4k3 will work at all speeds supported by the K3, but being software based, ?is subject to the performance of the computer and the whims of the Windows operating system above about 25wpm. ?This is why it will also support Winkey which uses a separate keying circuit than software. The same terminal can be used with Winkey ?as well.The Win4k3 terminal essentially does what the Elecraft utility can do, as well as the P3 , the difference email being that is has full programmability and a logging interface to ADIF files, Ham Radio Deluxe Logbook, DXLABS Keeper and N3FJP contest logs.It's actually a lot of fun. I know no CW but using the CW decoding of the K3, I was able to log 50 countries during one contest without any knowledge of CW. Sort of like PSKD.?73 Tom?

You've just answered a question about what the $100 S/W cw generation program is you referred to. Winkeyer is not a software package. It is actually a little box that plugs into your computer and radio. It is controlled by some program on your computer; I use Win4K3 for casual operation or N1MM+ for contesting. Your paddle plugs into the box so you can send by computer or by key. Winkeyer is a rather popular interface for a lot of software packages. I have one and prefer it to just telling my radio to key directly; I found this functions more smoothly. I operate mostly contesting these days for the purpose of getting a 5 band DXCC; I'm getting close. My performance in contesting has dramatically improved by integrating a number of functions, spectrum display, logging, and quick response CW (20-25 WPM). This is particularly important if you are going to put in many, many hours. I will never get to your level; I just don't have the low loss pipe between my ears and fingers. 73, Barry K3NDM ------ Original Message ------ From: "Chester Alderman" To: "'Barry'" ; "'Tom'" ; "'Elecraft'" Sent: 1/20/2017 7:26:49 PM Subject: RE: Re[2]: [Elecraft] New release of Win4K3Suite supporting the SDRPlay RSP2 >Hi Barry, > >Well I was keeping an eye on Win4K3 because I was looking for a >non-contest program that was more modern, but at the time I looked at >Win4K3 the only CW generation I could find was done by purchasing a >WinKey.

Like the SteppIR device, it should just be grabbing frequency data from the radio. I'm not sure if it uses polling or not to get this data, however, as I don't actually own the device yet (looking at purchasing the upgraded tuner for specifically this use case, assuming I can figure out how to make it work.) I saw in the programmer's reference there's some auto-info mode that has the radio emit frequency on front-panel operation, and the ATU may enable that. Unfortunately, the ATU doesn't indicate exactly how it does communication.

There were some circuits designed to "pull" the frequency of a crystal slightly - maybe a few kHz - but they did tend to be unstable. Pulled too far, the crystal oscillator would stop being controlled by the crystal at all and simply become a free-running oscillator. Many novices used "surplus" crystals from military gear and it was common to find several stations on the same frequency when the band was open. So we tinkered with ways to move the crystal frequency slightly by rubbing solder or pencil 'lead' (graphite) on it but one could only go so far or the crystal would stop oscillating. 73, Ron AC7AC From n1al at sonic.net Sat Jan 21 14:19:08 2017 From: n1al at sonic.net (Alan Bloom) Date: Sat, 21 Jan 2017 11:19:08 -0800 Subject: [Elecraft] K3: past chirp report In-Reply-To: <01b701d27407$c207a640$4616f2c0$@sbcglobal.net> References: <87D412FB-BDDF-4770-BE0C-72EB82881B78@w7kf.com> <81CF45EF-6F69-48A0-AA96-5A31BF16623E@widomaker.com> <1484917819537-7625920.post@n2.nabble.com> <002101d27347$2cca3f90$865ebeb0$@biz> <000001d2739e$5f920dc0$1eb62940$@biz> <6D.F2.24145.6C243885@smtp02.armstrong.cmh.synacor.com> <001101d27403$9e382810$daa87830$@biz> <01b701d27407$c207a640$4616f2c0$@sbcglobal.net> Message-ID: Yes I had a half dozen surplus crystals at the bottom of the 40 meter novice band.

K3 S/N 8334 with latest firmware. When I key the transmitter and speak or whistle into the mic, I get no RF output. I can hear myself in the monitor. If I enable VOX, speaking engages the transmitter, but no RF output. Engaging the TUNE function does produce RF output as expected. If I switch the mode to CW and tap the straight key, the radio transmits with expected output. If I THEN switch mode back to LSB, radio functions normally with expected output. Note that all of the above is with radio connected to a dummy load, so my antenna is out of the picture. Once I switch to CW, key the radio, and switch back to LSB as described above, transmit works fine until I power cycle the radio, or adjust the RF Power control (even if I just dial it down a couple watts and then right back to where it was). Either of those two events appears to disable SSB transmit until I 'kick' it by transmitting with CW. As far as I can tell, this behavior is ONLY on 80M. The rig is NOT in 'Test mode', and Xmit Inhibit is turned off in the menu. All other radio functions and bands seem to work FB. Any ideas ?

Unless you drive the audio as instructed in the manual, the power output will be erratic or non-existent. When you speak into the microphone, do you see 5 to 7 bars on the ALC meter? If not, you do not have adequate audio drive, increase the mic gain until that condition is realized. If you have a Heil HC6 or HC7 mic element, those have very low output levels and you may need to go to the MIC Gain High range. Note that the high range only applies to the front panel mic jack. Go to the K3 menu for MIC SEL and tap "3" to toggle the setting on/off. The high gain mic preamp is indicated by the icon "H'" in the display. 73, Don W3FPR On 1/21/2017 10:20 PM, Dave Fugleberg wrote: > I seldom operate 80M phone, so don't know if this is a new issue or not.

It's electrically fine just not quite where it should be. One alder tree has grabbed it (the one which broke it). I thought it unwise to use my chainsaw on a muddy, icy slope. So it will take a few more hours of work to reroute. I now have the classic kinked inverted V configuration antenna. The tuning is just slightly different. While I checked the bands during retuning I was hearing quite a number of folks on the air. Bugs and paddles both with the odd straight key now and then.

My space is very limited, and in particular (due to the need to rotate my existing dipole), there is no way to put up a vertical more than about 3m high, and no room for radials longer than a few meters. But the location is 35m above the ground and it is possible to add another rotatable horizontal dipole to my mast. So I am thinking about a 6m long dipole made of aluminum tubing. I have some that is about 20mm in diameter. I will make capacity hats for each side to add some end loading. Yes, I know the bandwidth would be very narrow. But I could live with a 3:1 SWR bandwidth of 30 kHz. I'm thinking about two possible configurations for loading coils: one coil in the middle, or two coils, each about halfway down each side of the dipole. I know that two coils would produce a more efficient antenna. But the one coil in the middle has two big advantages: it would allow me to feed the antenna via an isolated link, which would solve the common-mode problem without requiring a balun, and it would allow for easy tuning and matching. So what do you antenna experts think? One or two coils?

If placed horizontally they are not. Which could be meant as an advantage especially if laid on an attic floor which is wider than high (a bigger loop gives you better results in lower bands). BUT if mag loops are set that way, they are said lossy if the ground is less than a quarter wave below. Why in an attic? Avoids wind load, aesthetic dispute with your neighbors, corrosion to the variable condenser and balun. Advice: if you build one yourself ALL electrical connections must be silver soldered (every milli Ohms is worth it) 'cause high currents (up to 50 Amps), and access to the antenna should be strictly forbidden during transmit due to high voltage (10 kV or so). See AA5TB's calculator. Not usually mentioned: this should merely be considered as a transmit antenna as your bandwidth could be as low as 2.5 kHz in lower bands. So NO panadapter with a mag loop. Just forget it. Without a panadapter of course reciprocity principle applies, but when you QSY, you quite soon won't hear anything until remote re-tuning the loop. Therefore, when in-band searching around or want to use a panadapter, you better may have a separate wideband receive antenna like Beverage or K9AY. But you're lucky: the K3(s) has a separate receive antenna input HI (just press "Rx ANT"). :) See also the very helpful paper by the guru VK5LT: www.brisdance.com/vk4amz/files/Download/UnderMagLoop.pdf HTH, Christian F1GWR Le 22 janv. 2017 ? 04:19, Robert 'RC' Conley a ?crit : > are they directional? > > -- > May You Live Long and Prosper.... > what's life without a few dragons.... > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to f1gwr at free.fr From f1gwr at free.fr Sun Jan 22 08:25:56 2017 From: f1gwr at free.fr (C G) Date: Sun, 22 Jan 2017 14:25:56 +0100 Subject: [Elecraft] Very short 80m antenna References: <5541CB51-2205-48C3-A0F0-39D6685F22E4@free.fr> Message-ID: <444F89FB-762F-4BAA-93D5-93D9D0653E13@free.fr> Hi Vic, Please also consider the current "MAG LOOP ANTENNAS" thread on this list which fits your requirements as long as the loop is big enough (2 to 3m in diameter at least). 73, Christian F1GWR Le 22 janv. 2017 ? 13:34, Vic Rosenthal 4X6GP a ?crit : > Today I am limited to the bands from 7 MHz and up and I want to get on 80m.

Adjust the audio input level to produce 4 bars solid on the ALC meter with the 5th bar flashing. That usually means setting the soundcard output slider on the computer to about 75% and then adjusting the K3(S) MIC GAIN (actually LINE IN gain) to produce that condition. The onset of ALC is indicated by the 5th bar on the ALC meter. Adjust the desired power output level with the POWER knob (not the audio level). Elecraft transceivers control power differently than other amateur transceivers - set the K3 as indicated in the manual and ignore the internet advice (and some software instructions) which would have you set the power to full and adjust the power output with the audio level. That does *not* work with Elecraft transceivers. To do so will result in erratic power output. 73, Don W3FPR On 1/22/2017 9:39 AM, Jamie WW3S wrote: > Is it possible to display ALC while using the line in jack on the rear panel?

The problem is that I hadnt well understood... and really now need to read your (big) book. At this moment I have saved six macros for split/unsplit, THR15/THR07, AMP ON 65W-AMP OFF 100W, plus macros for the K-Pad for switching K3S keys PF1 (split/unsplit), APF ON/OFF, switching XFIL, pressing SPOT, PF2 (65W/100W).Again I have space for 4 other macros, not more. Really I need suggestions from your book to optimize the 8 K3S memories on M1 up to M8 and PF1 - PF2 and optimize the full 16 memories on K-Pad.I have a P3 but without SVGA module, so here I havent the other P3 memories. Another question for you: how you set your NB levels, if agc and dsp-agc? On my K3S NB seem to work barely only at higher if agc setting.

Hi Vic, Can you bond to the structure of your building near the base of a vertical? If so, it will serve as a very effective counterpoise.

Set the K3S for DATA A and the MIC SEL to LINE. Make sure nothing is plugged into the LINE IN jack in the rear because it will switch out the output of the internal soundcard. The internal soundcard setup is just like any other USB soundcard. Tell your application which soundcard to use and set the output (speaker) of that soundcard to about 75%. Then tell the application to transmit - with the K3S, you can use TX TEST mode or connect a dummy load so you do not transmit RF. Adjust the MIC GAIN (now LINE IN gain) to produce 4 bars solid on the ALC meter with the 5th bar flashing. Adjust the desired power with the K3S POWER knob. Yes, this is different than the common internet advice, but the K3(S) is different than other amateur transceivers. Use the information in the K3(S) manual when setting up soundcard data modes. 73, Don W3FPR On 1/22/2017 1:22 PM, Benny Aumala wrote: > Anybody with settings to K3s for WSPR 2.0? > K3S has in itself the sound card and works via USB to PC. > > Benny OH9NB > > --- > Avast Antivirus on tarkistanut t?m?n s?hk?postin virusten varalta. > https://www.avast.com/antivirus > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to donwilh at embarqmail.com From john at kk9a.com Sun Jan 22 15:28:38 2017 From: john at kk9a.com (john at kk9a.com) Date: Sun, 22 Jan 2017 15:28:38 -0500 Subject: [Elecraft] KXPA100 RF feedback Message-ID: <000301d274ee$1fda3bc0$5f8eb340$@com> If you don't find it, the problem will return.

There should be no connection to pin 1. If there is, correct it so the connector is wired like that shown in the XV Owner's manual - see Figure 7 on page 11. If you do not have the latest XV Owner's manual, download it. Yes, you should be able to leave the XV144 connected, and you should be able to work RTTY on 2 meters. 73, Don W3FPR On 1/22/2017 3:15 PM, stewart at gm4aff.net wrote: > I have been trying to make FSK work with my K3 since last September on > and off (excuse the pun).

You might have trouble finding someone to talk to. :) More seriously, why FSK? AFSK works quite well with all versions of K3 hardware and VOX works for TX. If you need more time for an antenna or preamp relay to pull in, there's a menu setting for delay TX after amp key. As I recall, the default is about 8 msec. 73, Jim K9YC From k6dgw at foothill.net Sun Jan 22 17:49:31 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 22 Jan 2017 14:49:31 -0800 Subject: [Elecraft] (OT redoux) MAG LOOP ANTENNAS In-Reply-To: References: Message-ID: I'm not sure about a mag loop inside a room, I've never tried mine that way. When used vertically outside, they tend to be insensitive to surroundings [trees, ground, you sitting under it] because the permeability of most such surroundings is 1. This may not be true if you're set up on the track of a railroad yard ... or if there's a lot of ferromagnetic material in your walls. If you try it, be aware of several things: 1. Small magnetic loops involve some very high voltages and circulating currents, even at surprisingly low powers. AA5TB has an on-line calculator and there is a similar one at http://www.66pacific.com/calculators/small_tx_loop_calc.aspx 2. The equivalent radiation resistance of small loops is extraordinarily low -- in the milliohms range. Your power will be split between the radiation resistance and the RF resistance of the conductors, which is higher than the DC resistance because of the skin effect. You really need to achieve the lowest possible RF resistance [high conductor surface area]. 3. Mag loops are resonant transformers or autotransformers. To radiate at all, they MUST be exactly resonant at your TX frequency. "Getting close and letting the ATU match it" will create a fairly effective dummy load. Bypass the ATU and tune the loop for exact resonance. 4. The usable bandwidth will be very low [i.e. you need to re-resonate the loop when you QSY, even a little]. As the circumference of the loop becomes smaller in relation to the wavelength [i.e. on lower frequencies for a fixed size loop], the BW can become smaller than the occupied BW of a SSB signal. Commercial mag loops [e.g. my Alexloop] are usable from 40 up. Tuning it on 40 is really touchy. It's easier on 20 and up. They tend to run in the $400 range. You can build one much cheaper, but remember #2 above. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/22/2017 6:16 AM, Robert 'RC' Conley wrote: > Guys; > I'm anticipating a move to a seniors villa and I know I will be unable to > to take my antenna farm and most of the ham shack.

Carl's suggestion to run the 5 and 50 W transmitter gain calibration appears to have solved the issue, although I have no idea why. Don, I'm familiar with how much drive the K3 wants from the mic, and have it set properly for my HC-5 element. The behavior was not erratic - it was easily repeatable using the steps I described. After running the calibrations, I can no longer repeat the issue. The only time I had ever previously run the calibrations was during final setup after assembling the radio a couple years ago. Is that something that one should do periodically, or after each firmware update? Hank, I did back up my configuration both before and after running the calibration, so I have that in my back pocket as well. Again, thanks to all who responded - I'll keep an eye on it and report back if it reappears. 73 de W0ZF On Sat, Jan 21, 2017 at 11:11 PM, Don Wilhelm wrote: > Dave, > > This is a classic case with Elecraft transceivers that do not drive the > audio sufficiently.

You should not *normally* have to do a TX Gain Calibration after a firmware upgrade. However, I do not know how old your prior firmware happened to be. There was a prior firmware upgrade which moved the location where the TX Gain Calibration data was stored, and after *that* particular update it was necessary to do the TX Gain Calibration in order to move the values to the new location. If something like that occurs again, it will be pointed out in the Firmware Release Notes. It would be wise to read *all* the Firmware Release Notes between the firmware that you had in your K3(S) and the most current level to see if any special actions are necessary. 73, Don W3FPR On 1/22/2017 6:54 PM, Dave Fugleberg wrote: > Thanks to all for your suggestions.

My tactic was to get as much wire up as high as possible while still being unobtrusive. I was running 10 watts or less, CW. In one location I had a tree about 20 feet away from a window at my operating desk. I slipped a fine wire out of the window (so I could still close it) and hooked it to some fishing line leader which I then tossed into the tree, succeeding in getting it about 20 feet above the ground. It was not visible and survived some surprising winds. Worked it against a counterpoise made from fine white wire held along the (apartment white) wall with pushpins. Where I had a 2nd (top) floor unit, I had good success with a thin white wire 'doublet' tacked onto the wall near the ceiling with the two halves running as nearly in opposite directions as possible I was able to get about 50 feet of wire up that way and made a lot of contacts including some DX. Of course being indoors brings you closer to all sources of noise and, depending upon the construction of the building a certain amount of "shielding". One apartment building had a flat roof. The manager okayed me installing a simple antenna on the roof. It never hurts to ask. In another top floor location I discovered I had an attic access door in one closet, so I installed a "doublet" in the attic just under the roof rafters. Got a full half wave on 40 in that space with a bend in each half. The "feeder" was open wire - thin white wires that passed through two tiny holes in the ceiling next to the wall at my operating position and down to the rig. It worked beautifully on 40 through 10 meters. On that one when I moved I never got into the attic space to remove the antenna, insulators, etc. I just cut the feeder at the ceiling and filled the tiny holes. Eventually someone needing to do work in the attic probably scratched their head wondering what that was - unless they were a Ham. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Robert 'RC' Conley Sent: Sunday, January 22, 2017 6:16 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] (OT redoux) MAG LOOP ANTENNAS Guys; I'm anticipating a move to a seniors villa and I know I will be unable to to take my antenna farm and most of the ham shack.

Indoors, you are within the loop of the AC lines, Ethernet cables, etc. Try to get out of the loop and use a balun to decouple the outside of the feed line if it's coax. Small wire like no. 20 enameled wire can be almost invisible from a few feet away. Another possibility is a temporary antenna. You can make a little stand for a mag loop and place it outdoors to operate and then bring it inside when you are done. I have a little game I play whenever I visit a new place. I ask myself "how would I put up an antenna if I lived here?" My wife is used to my walking around looking at trees, etc. Vic 4X6GP > On 23 Jan 2017, at 02:49, Ron D'Eau Claire wrote: > > Over the years I've done a fair bit of operating from inside apartments.

You probably have a bad coax-to-connector problem somewhere. If you're using PL259 type connectors, even commercially made and moulded types, it's not uncommon. The outer braid becomes detached at the point where the cable enters the connector. All too common a failing of those things, especially where cheap (braid over foil) type coax is used. (Cheap to the manufacturers, not to you when you perhaps bought a ready made lead...) Hope you find it. A simple loop or very short dipole and diode probe can help. Run the system at a lowish power where it will run without tripping, move the probe around the cables/connectors. You'll find any leakage that way. A good cable will hardly indicate, a faulty one will be "quite lively"... 73. Dave G0WBX.

I can though testify that the AlexLoop can work amazingly well from inside a frame house and even a stone house as I have tried this. It also works wonderfully from a hotel balcony; though I understand these are less common in W land for unfortunate reasons. Keep the magnetic loop off furniture with metal springs inside. The AlexLoop or Magnetic Loop is my antenna of choice for travel as it is so unobtrusive and yet amazingly can work. This sounds like snake oil so perhaps I am over enthusiastic. I have used the AlexLoop in a part time effort for a WPX contest. Operation was from Connecticut with the antenna inside my sisters house using KC1AV as my call. I worked 270 some Qs with a good 30% of these being with Europe. My power was 5 or 10 Watts - memory fails me on this point. I have at times found the AlexLoop out perform a Buddipole at full 1/4 wave length for twenty meters with two radials. How this could be well I can not answer. I am suspicious. At night it is surely easier to retune the antenna when changing bands than having to go outside and change the length of the antenna and its radials. The AlexLoop capacitor is within arm's reach. When possible for portable operation though I prefer an end fed dipole but this only works when staying with understanding friends or family. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Fred Jensen Sent: 22 January 2017 22:50 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] (OT redoux) MAG LOOP ANTENNAS I'm not sure about a mag loop inside a room, I've never tried mine that way. When used vertically outside, they tend to be insensitive to surroundings [trees, ground, you sitting under it] because the permeability of most such surroundings is 1. This may not be true if you're set up on the track of a railroad yard ... or if there's a lot of ferromagnetic material in your walls. If you try it, be aware of several things: 1. Small magnetic loops involve some very high voltages and circulating currents, even at surprisingly low powers. AA5TB has an on-line calculator and there is a similar one at http://www.66pacific.com/calculators/small_tx_loop_calc.aspx 2. The equivalent radiation resistance of small loops is extraordinarily low -- in the milliohms range. Your power will be split between the radiation resistance and the RF resistance of the conductors, which is higher than the DC resistance because of the skin effect. You really need to achieve the lowest possible RF resistance [high conductor surface area]. 3. Mag loops are resonant transformers or autotransformers. To radiate at all, they MUST be exactly resonant at your TX frequency. "Getting close and letting the ATU match it" will create a fairly effective dummy load. Bypass the ATU and tune the loop for exact resonance. 4. The usable bandwidth will be very low [i.e. you need to re-resonate the loop when you QSY, even a little]. As the circumference of the loop becomes smaller in relation to the wavelength [i.e. on lower frequencies for a fixed size loop], the BW can become smaller than the occupied BW of a SSB signal. Commercial mag loops [e.g. my Alexloop] are usable from 40 up. Tuning it on 40 is really touchy. It's easier on 20 and up. They tend to run in the $400 range. You can build one much cheaper, but remember #2 above. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/22/2017 6:16 AM, Robert 'RC' Conley wrote: > Guys; > I'm anticipating a move to a seniors villa and I know I will be unable to > to take my antenna farm and most of the ham shack.

A good Balun will have the right impedance ratio for the intended job, and the right internal impedance between the pairs of wires on the cores to provide a low return loss. It is not easy to get good performance over the full 160 to 6 meter range. These do not look like a good choice, unless you want to lose lots of signal in the Balun. 73, Mark W7MLG On Jan 23, 2017 7:50 AM, "Ken G Kopp" wrote: >From a career comm tech ... me. 75 ohm BNC's -are- different and have smaller center pins.

If you're calculating SWR, you don't need to convert them before you do the calculation -- as long as the units are the same.

Nowadays there are so many noise sources in buildings that getting a wire outside is worth the struggle. Indoors, you are within the loop of the AC lines, Ethernet cables, etc. Try to get out of the loop and use a balun to decouple the outside of the feed line if it's coax. Small wire like no. 20 enameled wire can be almost invisible from a few feet away. Another possibility is a temporary antenna. You can make a little stand for a mag loop and place it outdoors to operate and then bring it inside when you are done. I have a little game I play whenever I visit a new place.

Perhaps I'm not understanding what I hear, or why, but it almost always seems that when speakers (or headphones) are not closely matched to the designed impedance I notice some deterioration in output. Some mismatch doesn't seem too serious, but when the difference is high, it seems much more noticeable. On the other hand, I've also experienced that using headphones with higher sensitivity ratings (like most Sony ear buds) tends to provide much higher output. Most ear buds tend to be 32 ohm (16 at lest), but I find Sony ear buds usually work best as many of them have sensitivity ratings up around -108 dbm. I could very well be fooling myself! This topic was covered somewhat similarly back when folks, including me, were complaining about poor audio output from Heil headphones. The headphone portion of my Yamaha CM500 works a lot better than my Heil, but neither works as well as some ear buds. I don't really have another good pair of headphones around here to try. Also, it was interesting to see Eric's response to this question. He indicates that the rigs are spec'd at 4 ohms, and that 8 ohm speakers would diminish output somewhat. Anyway, maybe you could make this all a bit clearer. Thanks, Dave W7AQK From: Jim Brown On Mon,1/23/2017 9:22 AM, Walter Underwood wrote: > For portable operation, I use Apple EarPods.

Audio output stages have an internal impedance MUCH lower than the loads they are designed to drive. For example, a typical speaker output stage is designed to drive any load impedance greater than 4 ohms, but it's own internal impedance (also called "source impedance") is a small fraction of an ohm. The ratio between those two impedances is called the "damping factor," and a value of 100 is typical. Line level outputs for consumer gear are typically in the range of 200-400 ohms, and are designed to drive 47K. Pro line outs are typically 100 ohms, designed to drive 5-10K. The impedance of mics is defined as 5X their minimum load impedance. Output stages that feed plug-able jacks are usually built with resistors in series to protect the output devices from damage by a short when a jack is being inserted or is inserted improperly. Typical resistor values are in the range of 10-500 ohms. Headphone outputs are designed to feed headphone impedances between 8 and 500 ohms. The impedance of headphones is simply a ratio between voltage and current. Lower impedance headphones need less voltage but more current, higher impedance headphones need more voltage but less current. That series protection resistor tends to compensate for those differences. Engineers who design headphones understand all of this and they want their headphones to work with anything they are plugged into, so they tend to design for high voltage sensitivity. It's a pretty safe assumption that any "brand name" headphones are going to work with any well-designed headphone amp. The KX3 is a bit of a special case, because Wayne always designs for low battery drain, which means that his audio output stages are somewhat "current starved," so they don't provide a lot of output. As usual, I find his designs to be very good compromises in that regard. I find the KX3 plenty loud enough with any of the decent headphones I've tried, and pretty good in a quiet location with the internal speaker. I virtually always operate with cans, and use the speaker only for casual monitoring. I find the KX3 quite useful for chasing RFI or checking out temporary antennas. 73, Jim K9YC On Mon,1/23/2017 12:06 PM, w7aqk wrote: > Maybe you could expand on that somewhat as I'm still confused a bit. > Perhaps I'm not understanding what I hear, or why, but it almost > always seems that when speakers (or headphones) are not closely > matched to the designed impedance I notice some deterioration in > output.

Correction -- one-fifth of their minimum load impedance. For example, a 250 ohm mic should drive an input impedance no lower than 1.25K. Most pro mics are in the range of 150-250 ohms. Another point I forgot to mention. ALL electro-acoustic transducers (mics, loudspeakers, headphones) are very complex, and their equivalent circuits are also very complex, containing multiple reactive components and a few resonances. The impedance curve of a typical loudspeaker or headphone has a low frequency peak of hundreds of ohms, a broad minimum at the lower middle of its operating range, and rises rapidly with frequency as it approaches the top of its operating range. The impedance of a loudspeaker or headphones is defined as that minimum value of the impedance. Multi-way loudspeakers have two such drivers, each with its own equivalent circuit, fed respectively by low pass and high pass filters. 73, Jim K9YC From donwilh at embarqmail.com Mon Jan 23 16:35:33 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 23 Jan 2017 16:35:33 -0500 Subject: [Elecraft] Audio Output Impedance of the KX3 In-Reply-To: References: Message-ID: <9136181e-410e-861a-6aeb-659c3b75ce37@embarqmail.com> David, Let me try to respond and perhaps Jim will chime in a well. Modern audio amplifier output stages are very low output impedance devices. As such, they can produce as much power as the device connected will allow. In a practical design of course there is a limit to how much current the attached device (speaker or headphones) can draw from the amplifier. With that being said, the lower the impedance, the more current that will be drawn. Speakers are generally in the 4 ohm to 8 ohm region and a 4 ohm speaker will draw more current and develop more power than an 8 ohm speaker. The efficiency of a speaker makes a big difference in the amount of sound it produces. Headphones are a slightly different matter (but only slightly) in that they are typically higher impedance and the current will be lower, and the voltage across it can be higher, but they are more efficient than speakers so it usually does not matter. The efficiency of headphones is usually expressed in SPL - the higher the number, the greater the sensitivity. Impedance does not matter much except in some low efficiency Hi-Fi audiophile headphones. In an analogy, consider the AC power line - that is a very low impedance source of a fixed voltage. How much power is taken from the line depends on the impedance of the device plugged into it. Within limits, an audio amplifier shares some of the same characteristics even though its voltage and power are much more limited. 73, Don W3FPR On 1/23/2017 3:06 PM, w7aqk wrote: > Jim, > > Maybe you could expand on that somewhat as I'm still confused a bit. > Perhaps I'm not understanding what I hear, or why, but it almost always > seems that when speakers (or headphones) are not closely matched to the > designed impedance I notice some deterioration in output.

Mel, K6KBE From: Don Wilhelm To: w7aqk ; Elecraft Reflector Sent: Monday, January 23, 2017 1:35 PM Subject: Re: [Elecraft] Audio Output Impedance of the KX3 David, Let me try to respond and perhaps Jim will chime in a well. Modern audio amplifier output stages are very low output impedance devices. As such, they can produce as much power as the device connected will allow.? In a practical design of course there is a limit to how much current the attached device (speaker or headphones) can draw from the amplifier. With that being said, the lower the impedance, the more current that will be drawn.? Speakers are generally in the 4 ohm to 8 ohm region and a 4 ohm speaker will draw more current and develop more power than an 8 ohm speaker.? The efficiency of a speaker makes a big difference in the amount of sound it produces. Headphones are a slightly different matter (but only slightly) in that they are typically higher impedance and the current will be lower, and the voltage across it can be higher, but they are more efficient than speakers so it usually does not matter.? The efficiency of headphones is usually expressed in SPL - the higher the number, the greater the sensitivity.? Impedance does not matter much except in some low efficiency Hi-Fi audiophile headphones. In an analogy, consider the AC power line - that is a very low impedance source of a fixed voltage.? How much power is taken from the line depends on the impedance of the device plugged into it.?

So yo can use the usual formula for computing VSWR from forward and reflected voltages. In this nomenclature: VSWR = (VFWD + VRFL) / (VFWD - VRFL) In your case : VSWR = (675 + 50) / (675 - 50) = 1.16 Perfect to go! AB2TC - Knut Lynn W.

It all depends upon your operating preferences, times to get on the air, and for the next few years in the solar doldrums. 20M should be your daytime band; I hear little activity on 15M lately. 20M is pretty much dead by sundown these days. 15M is my favorite band during the active sun, but we have a few years for those days to come. 40M or 80M should be your night time bands, though 40M is also quite useful daytime and lots of activities, such as special events, contests, SOTA and SKCC stations, etc. do use daytime 40M quite a bit. 80M has spurts of good activity at night, but virtually nothing daytime except nearby ground wave. Therefore, if your time on the air is limited to mostly evenings, then 80M and 40M would be the most useful. If you plan on some daytime QSOs or daytime on weekends, I'd pick 20M and 40M. That would also be a good combo if you plan on any weekend work in the field such as the FYBO, QRPTTF, Field Day, and the like, or most contests in general. Your mileage may differ, and others may feel differently.

The coupler connects to the P3 using a 4-pair twisted pair cable with RJ-45 connectors on each end. You might be able to reverse engineer one, but a) why bother? (the Elecraft product is priced about right), and b) you might find that no one will lend you one to reverse engineer the coupler interface.

I have a K1-4 (40-30-20-15) I bought in about 2005. Our current position in the solar cycle says 20M for daytime and either 30 or 40 for nighttime. The choice between 30 and 40 would be personal. I've had better luck on 30m with QRP than on 40m over the years. I have never made a contact on 15 with the K1. It's just too spotty to depend on QRP there. When it's open, it's really open, but it's the luck of the draw. 20M has always been my favorite band. These days weekday CW activity is kind of sparse. I have almost NO luck at the 20M QRP freq, but I can nearly always scare up a contact below 14.025 if I want.

I do a lot of QRP, especially in DX contests. I wouldn't dream of hanging out on "a QRP frequency," and I never sign /QRP. If I get into a chat, I will say that I'm running 5W. I'll reinforce the recommendation of 30M as a great band. The 200W power limit and no voice modes is a major advantage for those with limited stations or running QRP, antennas are of more reasonable size, and propagation is often quite good. 73, Jim K9YC From wunder at wunderwood.org Wed Jan 25 14:13:16 2017 From: wunder at wunderwood.org (Walter Underwood) Date: Wed, 25 Jan 2017 11:13:16 -0800 Subject: [Elecraft] Powered Speaker for KX1 In-Reply-To: <1954836863.930493.1485369817455@mail.yahoo.com> References: <1954836863.930493.1485369817455@mail.yahoo.com> Message-ID: I used this little audio amp with my KX3.

Message-ID: <00CB3AFF-4FF8-4F9F-9E3F-9385BED668E6@i29.net> Hi to the group I have a friend with the following equipment. KX3 with built in tuner. KXPA100 with built in tuner. KPA500 KAT500 50 ft of LMR400 coax R9 vertical. The KPA500 is not in the circuit at this time. We try to tune the KPA500 using the station set for 20 watts and a hand key. The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit over a tuning cycle and I think that is what is causing the trouble. Is anyone else using this combination of equipment and can give us some guide lines on setting up each piece of equipment and a procedure to tune up the KAT500 without hurting the KXPA100? Thanks to anyone that can help as this has turned into an expensive problem that has destroyed three pieces of equipment. Ken.

Some have customized their own boards for other bands, notably 160m and 10m. When I built a K1 in 2000, only two-band filter boardz were available. I built two filter boards, one for 40m/20m, and one for 30m/15m. I used those until the KFL1-4 four-band board for all four of those bands was available. I converted the 40m/20m KFL1-2 to 80m/17m. Without any doubt or question, if I were limited to one two-band board, 40m/20m would easily be my choice even as we head further into a long (perhaps very long) period of minimal solar activity.

What do you see with a dummy load on KXAT100 with both ATUs By-Passed? If not near 1:1, then start here and find out why. Once this checks, move dummy load to KAT500 output.

Sorry K3s, the P50VDG will remain in place! Hi Jim, I bought an ARR GasFET for 6M when I still lived in Chicago, and still use it with my K3 at the RX antenna patch point.

Not true. Yes, at the antenna end of the feedline is better, but the NF will apply to whatever signal the preamp sees. AND it strongly depends on how noisy our QTH is as compared to the circuit noise withing the radio/preamp. Preamps won't help much if you have a lot of RX noise. A good rule of thumb is that you are not limited by circuit noise if the noise level increases by 10 dB when you connect the antenna to the radio/preamp. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Jan 25 19:45:45 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 25 Jan 2017 16:45:45 -0800 Subject: [Elecraft] Is it just me?

(outside influences such as sky temperature, local noise sources, etc notwithstanding) So if you place a preamp with a NF of .5 dB at the "rig end" of a feedline run that exhibits 3 dB of loss at the frequency involved, you now have an effective noise figure of 3.5 dB ahead of your receiver. Placing the preamp at the antenna has an obvious advantage of reducing that NF by 3 dB.

My 6M antenna is at the other end of 350 ft of LDF5-50, 0.9 dB loss. It's a SteppIR, so I also use it for legal limit on the HF bands. So my preamp is in the shack. If it was practical for me to install a dedicated 6M antenna at 120 ft (which is where the SteppIR is), I would. But it isn't practical. It's important to realize that every engineering problem is different, most solutions are compromises, and which set of compromises are best for any given situation depend on many factors. In this case, real estate, the cost of another tower, somewhere to put another tower, the hard line that I can scrounge used at a good price, etc. And yes, I'd love the extra 2-3 dB that a better 6M antenna would provide. 73, Jim K9YC On Wed,1/25/2017 4:54 PM, Ken Arck wrote: > So if you place a preamp with a NF of .5 dB at the "rig end" of a > feedline run that exhibits 3 dB of loss at the frequency involved, you > now have an effective noise figure of 3.5 dB ahead of your receiver. > Placing the preamp at the antenna has an obvious advantage of reducing > that NF by 3 dB.

It works well. I would suggest a menu change to 5 watt tuning with the KX3. Do not tune everything at once. Big error. Do you have a tuner in the KXPA100? If so set on "Man" then tune the KX3 into the KAT500. This will stop what you are seeing. Too many tuners going at once will cause what you are seeing. If that doesn't work, turn off the KX3 tuner and use only the Kat500.

There is a setting in the MENU to turn off the tuner in the KXPA100 which we did and have to keep watching as the equipment keeps wanting to turn it back on. The problem we are having is tuning the KAT500. Hi SWRs are sent back to the KXPA100 and it trips out. I was hoping there is someone out there that is making this work.

Of course that is in the winter time, and things should get a bit better as we get closer to summer. Still, for the near future the higher bands won?t be very effective. During the (rather lengthy) low parts of the last cycle the MUF dropped below 80 meters for long periods of time at night, and even 20m wasn?t very effective during the day. I would consider some combination that includes 80 meters if you plan on operating at night. It is the higher band that would give me trouble deciding, with 40, 30 and even 20m providing interesting possibilities. I kind of like K9YC?s suggestion of 30 meters where CW shines so well. In any case, make a decision and enjoy it.

Hi Harry - I had lost your original message - and I had a draft I was going to send to you - but couldnot find your original message . So here is a paste of? it? . FWIW- and I had concluded exactly your first line . The guy who just was talking about 80 and MUF has some thoughts dunno - here? in Phoenix - ther are quite a few W6 guys to chew the fat with inthe winter - but summers are? just no fun.. Guess I live in a 30 meter hole - Most times I? find nothing on 30 other than special event or DXpedition stations and the W0ERE 2 watt beacon . Once in a while a random rag chew . Yes almost always some digital but we are talking CW I think . Then big pileups on a DX station and it all goes away when the DX quits . Contrast that to 40 Cw and virtually always something to work. So I would suggest if you have a receiver - listen to 30 and 40 and 20 at the times you will mostly operate and see whats best in your area. RE the 200 watts ?????

At this point in the solar cycle, we are already seeing the MUF drop below both 40 and 80 meters at night. Of course that is in the winter time, and things should get a bit better as we get closer to summer. Still, for the near future the higher bands won?t be very effective. During the (rather lengthy) low parts of the last cycle the MUF dropped below 80 meters for long periods of time at night, and even 20m wasn?t very effective during the day. I would consider some combination that includes 80 meters if you plan on operating at night. It is the higher band that would give me trouble deciding, with 40, 30 and even 20m providing interesting possibilities. I kind of like K9YC?s suggestion of 30 meters where CW shines so well. In any case, make a decision and enjoy it.

Message-ID: <201701260840.v0Q8ejdP008064@mail40c28.carrierzone.com> Seems there are two threads dealing with the same topic (also: Re: [Elecraft] Advanced Receiver Research P50VDG 6M Preamp): I have both the PR6-10 (installed at the K3) and a ARR P50VDG installed at tower-top of my main 6m antenna. I run 70-foot of 7/8-inch Heliax to the box with the ARR preamp and coax TR relay. The ARR preamp feeds a run of RG-213 back to the bypass input connector of the PR6-10. So I can compare directly the ARR or the PR6-10. The ARR has more gain and slightly less NF so in its position near the antenna, works better for very weak signals, but the PR6-10 fed thru the 7/8-inch line is very close in performance. Both have enabled me to copy 6m eme signals with the single 6-element 6m yagi. This is largely because sky noise (which includes neighborhood noise) is high on 6m which limits the effectiveness of a low noise preamp. Within the 6m eme community its felt that if line loss is kept < 1 dB, there is little advantage to placing a low noise preamp near the antenna. In my particular situation I see a slight advantage (too small to really be quantified) in having my ARR at the antenna. I use it vs the PR6-10 with that antenna. I have a 3-element 6m yagi which I use the PR6-10 as that antenna is on another coax run. PR6-10 is also active on 10m with my triband yagi. So if you can place a low noise preamp at the antenna, that is ideal, but if you run low loss cable having it at the radio is almost as good. Not sure why anyone would run a cable with 3-dB loss for any reason? Half your transmit power is turned into heating the coax (unless you need a cheap dummy load?). I run 6m-eme with my KXPA100 driving a surplus TV amp (Harris) with 11w for 1000w output. I run the K3 at 1.7w with 3-dB attn applied on the KXPA100 to achieve 11w output. I use DIGIOUT1 to switch the PR6-10 on/off. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From duklaet at broadpark.no Thu Jan 26 05:38:57 2017 From: duklaet at broadpark.no (=?iso-8859-1?Q?=22Hjalmar_Dukl=E6t=22?=) Date: Thu, 26 Jan 2017 11:38:57 +0100 Subject: [Elecraft] What Two Bands would you pick for a K1?

Message-ID: <578AD2F96E0240DD9E1C88B47935E796@LAPTOPEPVQLR1I> I think on most email programs there is a "reply" and a "reply all" option. On mine, at least, if I hit "reply all" it will go to the sender and to the reflector. So, if you want to avoid that kind of duplication, one must remove the excess addressee, which is fairly simple. There is benefit to sending it to both! If the recipient is a digest subscriber, He will get his response forthwith, which may well be preferable. That way he won't have to wait until the next digest is distributed to see the response. If the recipient gets all messages as they are sent, then it can be duplicative. However, you don't know which is the case. Since I subscribe to digest mode on some reflectors, sending to both can be helpful to me, if I am the intended beneficiary, but that won't be the case for everyone. I also think having a choice between "reply" and "reply all" is very beneficial. Sometimes you really only want to reply to the sender, and it should be your choice to do so easily. At least one reflector made an issue of this, and removed the "reply" option, forcing replies to go to the reflector--unless you go to great lengths to alter that. I strongly oppose this attempt to "control" how and to whom a response is set. Another problem, primarily involving digest subscribers, is how to properly respond. Too many just hit the "reply" button and end up copying the entire digest, rather than just copying over the pertinent parts of the single post. This is most annoying. If the digest mode is better for you, part of the "price" you pay for that convenience is to have to do a little cut and pasting on any reply you might make. Yes, it takes a little extra work, but how often do you have to do it? Copying over part of a post may be very helpful for continuity, but not the whole darned digest!!! Also, if you receive in digest mode, and someone replies by copying over the entire digest, then you have to scroll endlessly to get past that post! It is just plain inconsiderate! Digest subscribers need to be very careful about how they formulate their responses. Hopefully I practice what I preach! In this case I didn't copy over anything, since I think my comments are self explanatory. If I had needed additional context, I would have cut and pasted from the digest. It really only takes a few extra key strokes.

All of the other bands stay above 11W across their respective bands. The other interesting characteristic is that if I lower the power to 5W, there is no drop- it stays at 5W across the entire 20M band. Other relevant data: -All data is taken post Cal -The drop on the 12V line when I key up the transmitter (set for 12W) is the same at both ends of the 20M band: 13.9 to 13.4V as measured by the K3s. -Output power is measured with an LP-100A and is the same as shown on the K3s. -The 20M BPF & LPF are flat to a few tenths of a dB and the SWR<2:1 across the band. -The voltages and waveforms on the drains of the two FETs are identical, and look OK to me. -The bias on both FET gates is ~2.6VDC. -The RF input signal to the KLPA3A (as measured at the XVTR output) is the correct level and remains constant on all bands as the freq is moved across the band. All spurious are down >50 dB. I also verified that the signal level remains constant over the 20M band when the output power is dropping. This suggests that the problem is not with the AGC or with any components ahead of the KLPA3A. Since the problem does not occur at reduced (5W) power, it appears to be due to some non-linearity. The FETs would be a logical candidate if it were not for the fact that the problem only occurs on one band. I checked the temps on all of the 20M LPF toroids and didn't observe any rise. I have no idea where else to look for a band specific non-linearity and have run out of ideas on what else to check. Any suggestions would be greatly appreciated.

I have about 85 feet of regular old RG-213 to the beam and so far, 153 countries confirmed on six along with WAS & WAC. Conversely, I have Landwehr pre-amps at the antennas for 144/222/432. Even though the feed-line on 432 is 7/8" Heliax, switching on the pre-amp makes a noticeable difference. When I had a regular K3, I didn't see a lot of difference between the Elecraft outboard pre-amp and the ARR unit. That said, my new K3S does not need the external pre-amp since it basically has the equivalent built-in, which is another BIG plus for going with the later version K3S. 73, Charlie k3ICH -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Josh Fiden Sent: Thursday, January 26, 2017 12:46 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Is it just me? 3 dB feedline loss is not a practical number.

Hi The kx3 or kx2 and kxpa100 will work just like a k3 and a kpa500. Make sure the kxpa100 is enabled in the kx3. Make sure the tuner is bypassed in both the kx3 and kxpa100, also make sure the power is lower than 30w out. Then you need the kat500 which will tune the antenna. In this combo, the kpa500 must be set to the band you wish to use.73 Tom Sent from my Samsung Galaxy smartphone. -------- Original message --------From: Don Wilhelm Date: 2017-01-25 10:58 PM (GMT-05:00) To: Kenneth Christiansen , Kenneth Christiansen Cc: Elecraft at mailman.qth.net Subject: Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500? Ken, If you are using TUNE (and not ATU TUNE), then there is no need for a macro. Just go into the menu and set the KX3 TUN PWR entry as desired. The ATU TUNE works with the KX3 alone or the KX3/KXPA100/KXAT100, but I don't know what happens if you use it with the KPA500. 73, Don W3FPR On 1/25/2017 10:44 PM, Kenneth Christiansen wrote: > Hi again to the group > > Jim and Fred both recommended lower power below 10 watts so the KXPA100 does not kick in.

Nor does it give you a guaranteed accurate representation of your transmit signal - it is simply due to some leakage path. It may be OK to view as representative of your transmit waveform, but the amplitude is not necessarily correct. 73, Don W3FPR On 1/26/2017 1:16 PM, Don Baucom wrote: > This may have been this way the whole time and I did not notice.

As near as I can determine without uncoiling it, I calculate about 75 feet for each piece. I was planning to make my own connectors, but I have not had an application that would utilize the hard line's low loss. And, I'm too old to do it now. As you may know, for a size comparison, a piece of RG8 easily slips into the center conductor with room to spare. I would sell it, but not try to ship it. I suggest a buyer would pick it up in person. I live in west central Minnesota. I don't remember the brand name if that matters. I could see what it says on the cable. The copper itself must have considerable value. A person can't go wrong if we agree on a win-win price.

It seems to happen in SSB mode when contesting and running. I notice that sometimes the P3 will be sluggish transitioning back to RX from TX. Sometimes it can be a 2 to 3 second delay. If I begin another CQ call before it completely switches to RX, the P3 will display a TX wave form. I first noticed it when running N1MM logger, and someone on the reflector here gave advise to reduce the polling from N1MM. That seemed to help when running N1MM. But there have been a couple of times when not running N1MM, in SSB, I notice the hang delay in the P3 from switching back to RX, and have been able to reproduce displaying my TX wave form by going back into TX just before it seems to want to transition back to RX. Not sure what causes the sporadic delay. I'd say 99.9% of the time there is no delay in switching. Kinda strange, but no biggie.

Guess you would consider it NOS. The wooden spools themselves are in poor shape. Not certain that it is Andrews coax, if not, its a very good copy. Like John says, you buy it when you find a good bargain. Same with connectors; at swap meets, used connectors are typically no more that $5 each. I guess if someone needs some hardline now, and could pick it up locally, yours would be a fair price. You can also often find 7/8", 100 - 130 ft hardline pieces for about $1 a foot. Sometimes they may have a connector on one end included. BTW, I agree with others, this is not an subject Elecraft and does not belong here.

The replacement router is the same model as its predecessor (Cisco EA4500). I had good, but possibly imperfect, records of the port forwarding setup which I reproduced on the replacement router. Now, pressing POWER on the Control K3 turns the Remote K3 ON and operates correctly, but when I turn off the Control K3, the Remote K3 stays on. If I then tap the POWER button on the Remote K3, its screen goes solid amber with no LCD segments lit, but it does not fully power down. It also becomes catatonic, its own POWER button useless, but it's still responsive to power on from the Control K3. I have Restarted both RemoteRig boxes to no avail. I have confirmed that my DDNS real IP address is correct. In case it's material, here are the port forwards I have in place: RRC UPD Cmd 10000 RRC UDP Audio 11000 RRC Web 5058 RRC Telnet 5059 RRC SIP 5088 All port forwards are set the same for both internal and external use, both TCP and UDP protocols, LAN address of the RRC.

There is very little rework when adding options - the "Rework" consists mainly of removing the jumpers that are normally installed when building up the basic CW K2 and removing/changing at most one capacitor for each option (the KNB2 requires 3 resistors to be changed). A careful perusal of the installation procedure in the manuals for the options that you wish to add. The headers required come with the options that you purchase initially. For those options that you may want to add later, it is a simple matter to install the female headers on the RF board and Control Board and use wire jumpers, and perhaps a capacitor or two in place of the actual rework eliminators. Download and identify the headers required. The most complex part of the rework eliminators is the KNB2 and the K60XV. I do not recommend making the board changes (C71 value and D19/D20 addition) until you actually have the K60XV option ready to install. The "Rework Eliminator" boards that you need are easily fabricated on perfboard and strips of male pins. For the K160RX, you need only the header and a bent component lead for a jumper - stick the jumper wire in the header and do not install W1. For the KAF2, you need only the 3 pin and 5 pin female headers mounted on the Control Board - do not install the wires for R18 and R19, but stick jumper wires made from component leads into the headers. For the KNB2, you will need the perfboard and 8 pin male header - on the RF board install a 2.7k resistor at R88 and a wire at the R89 location. Your plug-in "eliminator" needs 3 resistors - a 470 ohm, a 100 ohm and a 680 ohm. The 470 ohm resistor goes between pins 1 and 5, the 100 ohm resistor goes between pins 1 and 6, and the 680 ohm resistor between pins 6 and 5. For the KSB2, you need to install 3 pin headers at J9 and J10 and a 12 pin header at J11. bend 2 wire jumpers to plug into J9 and J10 - from pin 1 to pin 3 (do not install W2 and W3) and on a 12 pin male header strip on perfboard solder a .001uF capacitor between pins 7 and 12 - do not install C167. That takes care of all the "homebrew Rework eliminators" except the K60XV option. Since I do not recommend installing that until the K60XV option is built and ready to install, I have left that off the list. The VFO and PLL R30 voltages change with the addition of the K60XV changes and cannot be properly tested until the K60XV option is actually installed. If you want to do a partial install of the K60XV, put a 3 pin female header at J15 and put the leads of the 4.7pF capacitor into pins 1 and 3 of that header rather than soldering it to the RF board. You can also install the 8 pin female header at J13 and put a wire jumper between pins 3 and 5 (leave out W6 jumper). BUT change the value of C71 and add D19/D20 as well as the coax cable only after you have the K60XV option built - that is only one capacitor to change. If you want to install the headers at P3 and P6, you can do that at any time - no jumpers are required - one header is supplied with the KAT2 option and another with the KBT2 - both are supplied with the KPA100 kit. So there you have the complete instructions for installing the "Rework Eliminators" without buying the full kit. 73, Don W3FPR On 1/27/2017 6:28 PM, Harry Yingst via Elecraft wrote: > > I decided to build another K2 (since I foolishly sold my first one) I figured this time around I would use some Rework Eliminators. > > When I checked unpcb.com I found that they no longer stock them. > > Does anyone have an unused set with the additional components (full kit) that they want to sell? > From hlyingst at yahoo.com Fri Jan 27 20:23:23 2017 From: hlyingst at yahoo.com (Harry Yingst) Date: Sat, 28 Jan 2017 01:23:23 +0000 (UTC) Subject: [Elecraft] Building a K2, Does anyime have a set of rework e In-Reply-To: <6ad63840-78d6-d3c8-527b-1fd6e8a21019@embarqmail.com> References: <74466328.2292764.1485559684045.ref@mail.yahoo.com> <74466328.2292764.1485559684045@mail.yahoo.com> <6ad63840-78d6-d3c8-527b-1fd6e8a21019@embarqmail.com> Message-ID: <453543801.2372044.1485566603012@mail.yahoo.com> Thank you From: Don Wilhelm To: Harry Yingst ; Elecraft Reflector Sent: Friday, January 27, 2017 8:12 PM Subject: Re: [Elecraft] Building a K2, Does anyime have a set of rework e Harry, If you are ordering the options you want to include with the K2, there is little need for the Rework Eliminators.?

If you want to include the full "homebrew Rework Eliminators", you will have to add the standoffs for each option. Refer to the Elecraft manuals for each option and order the required standoffs and mounting hardware if you want to do a complete job. If you do not want to remove the K2 heatsink when adding options, you should order the 2 pin header for P6 (KAT2 manual or KPA100 manual), the standoff for the K160RX and the standoff for the K60XV. Those are the ones that are covered by the K2 heatsink. The other standoffs can be easily added without removing the heatsink - just remove the bottom cover. 73, Don W3FPR --------------------------------------------------- Harry, If you are ordering the options you want to include with the K2, there is little need for the Rework Eliminators.

A careful perusal of the installation procedure in the manuals for the options that you wish to add. The headers required come with the options that you purchase initially. For those options that you may want to add later, it is a simple matter to install the female headers on the RF board and Control Board and use wire jumpers, and perhaps a capacitor or two in place of the actual rework eliminators. Download and identify the headers required. The most complex part of the rework eliminators is the KNB2 and the K60XV. I do not recommend making the board changes (C71 value and D19/D20 addition) until you actually have the K60XV option ready to install. The "Rework Eliminator" boards that you need are easily fabricated on perfboard and strips of male pins. For the K160RX, you need only the header and a bent component lead for a jumper - stick the jumper wire in the header and do not install W1. For the KAF2, you need only the 3 pin and 5 pin female headers mounted on the Control Board - do not install the wires for R18 and R19, but stick jumper wires made from component leads into the headers. For the KNB2, you will need the perfboard and 8 pin male header - on the RF board install a 2.7k resistor at R88 and a wire at the R89 location. Your plug-in "eliminator" needs 3 resistors - a 470 ohm, a 100 ohm and a 680 ohm. The 470 ohm resistor goes between pins 1 and 5, the 100 ohm resistor goes between pins 1 and 6, and the 680 ohm resistor between pins 6 and 5. For the KSB2, you need to install 3 pin headers at J9 and J10 and a 12 pin header at J11. bend 2 wire jumpers to plug into J9 and J10 - from pin 1 to pin 3 (do not install W2 and W3) and on a 12 pin male header strip on perfboard solder a .001uF capacitor between pins 7 and 12 - do not install C167. That takes care of all the "homebrew Rework eliminators" except the K60XV option. Since I do not recommend installing that until the K60XV option is built and ready to install, I have left that off the list. The VFO and PLL R30 voltages change with the addition of the K60XV changes and cannot be properly tested until the K60XV option is actually installed. If you want to do a partial install of the K60XV, put a 3 pin female header at J15 and put the leads of the 4.7pF capacitor into pins 1 and 3 of that header rather than soldering it to the RF board. You can also install the 8 pin female header at J13 and put a wire jumper between pins 3 and 5 (leave out W6 jumper). BUT change the value of C71 and add D19/D20 as well as the coax cable only after you have the K60XV option built - that is only one capacitor to change. If you want to install the headers at P3 and P6, you can do that at any time - no jumpers are required - one header is supplied with the KAT2 option and another with the KBT2 - both are supplied with the KPA100 kit. So there you have the complete instructions for installing the "Rework Eliminators" without buying the full kit. 73, Don W3FPR On 1/27/2017 6:28 PM, Harry Yingst via Elecraft wrote: > > I decided to build another K2 (since I foolishly sold my first one) I figured this time around I would use some Rework Eliminators. > > When I checked unpcb.com I found that they no longer stock them. > > Does anyone have an unused set with the additional components (full kit) that they want to sell? > From k9yeq at live.com Fri Jan 27 21:14:39 2017 From: k9yeq at live.com (Bill Johnson) Date: Sat, 28 Jan 2017 02:14:39 +0000 Subject: [Elecraft] Building a K2, Does anyime have a set of rework e In-Reply-To: References: <74466328.2292764.1485559684045.ref@mail.yahoo.com> <74466328.2292764.1485559684045@mail.yahoo.com> Message-ID: The only Re-Work eliminator I found helpful was the Mic connector.

That is not part of the Rework Eliminators, but a separate product. If you want to try several different microphones with the K2, it is an easy way to do that. If you have only one microphone that you want to use with the K2, it is not necessary - plug the K2 microphone configuration header for your desired microphone and let it go at that. The IMA is handy for those who want to use microphones from various rigs with the K2. 73, Don W3FPR On 1/27/2017 9:14 PM, Bill Johnson wrote: > The only Re-Work eliminator I found helpful was the Mic connector.

Last night I was having a little play in the 160m contest and the k-pod started to play up almost 50% of the time so I had to do something. I picked a snap on toroid out of the misc box I have on the desk and clipped it on. I have no idea of the value type or anything else but magically the problem stopped. So it is/was RF getting in down the k-pod to K3 connecting lead. I am using the factory supplied lead and since it is quite short and nothing to do with the fact I couldnt fit more than one turn through the toroid if I wanted to the toroid is just one turn clipped over the connecting cable. While I shouldnt say its cured I can say my problems went away for the rest of the contest that I took part in. Time will tell if the problem on other bands have gone as well or I may require another toroid. 73 to all es gdx Tony G6GLP From glcazzola at alice.it Sat Jan 28 06:22:59 2017 From: glcazzola at alice.it (glcazzola at alice.it) Date: Sat, 28 Jan 2017 12:22:59 +0100 (CET) Subject: [Elecraft] new beta firmware for K3 - K3S Message-ID: <159e4d064bc.glcazzola@alice.it> Just installed version 5.56 that seem to be a release of 6 january 2017.Work well, I think.

Thank you to the three people that responded to this so far but each of you accused me of having my friend run three tuners in a row. The KX3 turns it's tuner off when it senses the KXPA100 is connected and turned on. There is a setting in the MENU to turn off the tuner in the KXPA100 which we did and have to keep watching as the equipment keeps wanting to turn it back on. The problem we are having is tuning the KAT500. Hi SWRs are sent back to the KXPA100 and it trips out. I was hoping there is someone out there that is making this work. I have a K3S myself and a KAT500 and they work perfectly together at 25 watts for tuning than the full 500 watts after it is tuned. My friend does not have a K3S so we need to make the KX3 and KXPA100 work. Thank you KEN.

The SWR of the KAT500 changes quite a bit over a tuning cycle and I think that is what is causing the trouble. Is anyone else using this combination of equipment and can give us some guide lines on setting up each piece of equipment and a procedure to tune up the KAT500 without hurting the KXPA100?

Refer to the Elecraft manuals for each option and order the required standoffs and mounting hardware if you want to do a complete job. If you do not want to remove the K2 heatsink when adding options, you should order the 2 pin header for P6 (KAT2 manual or KPA100 manual), the standoff for the K160RX and the standoff for the K60XV.? Those are the ones that are covered by the K2 heatsink.? The other standoffs can be easily added without removing the heatsink - just remove the bottom cover. 73, Don W3FPR --------------------------------------------------- Harry, If you are ordering the options you want to include with the K2, there is little need for the Rework Eliminators.? There is very little rework when adding options - the "Rework" consists mainly of removing the jumpers that are normally installed when building up the basic CW K2 and removing/changing at most one capacitor for each option (the KNB2 requires 3 resistors to be changed).? A careful perusal of the installation procedure in the manuals for the options that you wish to add.? The headers required come with the options that you purchase initially. For those options that you may want to add later, it is a simple matter to install the female headers on the RF board and Control Board and use wire jumpers, and perhaps a capacitor or two in place of the actual rework eliminators.? Download and identify the headers required. The most complex part of the rework eliminators is the KNB2 and the K60XV.? I do not recommend making the board changes (C71 value and D19/D20 addition) until you actually have the K60XV option ready to install.? The "Rework Eliminator" boards that you need are easily fabricated on perfboard and strips of male pins. For the K160RX, you need only the header and a bent component lead for a jumper - stick the jumper wire in the header and do not install W1. For the KAF2, you need only the 3 pin and 5 pin female headers mounted on the Control Board - do not install the wires for R18 and R19, but stick jumper wires made from component leads into the headers. For the KNB2, you will need the perfboard and 8 pin male header - on the RF board install a 2.7k resistor at R88 and a wire at the R89 location. Your plug-in "eliminator" needs 3 resistors - a 470 ohm, a 100 ohm and a 680 ohm.? The 470 ohm resistor goes between pins 1 and 5, the 100 ohm resistor goes between pins 1 and 6, and the 680 ohm resistor between pins 6 and 5. For the KSB2, you need to install 3 pin headers at J9 and J10 and a 12 pin header at J11.? bend 2 wire jumpers to plug into J9 and J10 - from pin 1 to pin 3 (do not install W2 and W3) and on a 12 pin male header strip on perfboard solder a .001uF capacitor between pins 7 and 12 - do not install C167. That takes care of all the "homebrew Rework eliminators" except the K60XV option.? Since I do not recommend installing that until the K60XV option is built and ready to install, I have left that off the list. The VFO and PLL R30 voltages change with the addition of the K60XV changes and cannot be properly tested until the K60XV option is actually installed.? If you want to do a partial install of the K60XV, put a 3 pin female header at J15 and put the leads of the 4.7pF capacitor into pins 1 and 3 of that header rather than soldering it to the RF board. You can also install the 8 pin female header at J13 and put a wire jumper between pins 3 and 5 (leave out W6 jumper).? BUT change the value of C71 and add D19/D20 as well as the coax cable only after you have the K60XV option built - that is only one capacitor to change. If you want to install the headers at P3 and P6, you can do that at any time - no jumpers are required - one header is supplied with the KAT2 option and another with the KBT2 - both are supplied with the KPA100 kit. So there you have the complete instructions for installing the "Rework Eliminators" without buying the full kit. 73, Don W3FPR On 1/27/2017 6:28 PM, Harry Yingst via Elecraft wrote: > > I decided to build another K2 (since I foolishly sold my first one) I figured this time around I would use some Rework Eliminators. > > When I checked unpcb.com I found that they no longer stock them. > > Does anyone have an unused set with the additional components (full kit) that they want to sell? > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k9yeq at live.com From kw9e at wi.rr.com Sat Jan 28 11:37:58 2017 From: kw9e at wi.rr.com (Peter LaBissoniere) Date: Sat, 28 Jan 2017 10:37:58 -0600 Subject: [Elecraft] Solar Cycles In-Reply-To: <1047209402.239051.1485523721454@mail.yahoo.com> References: <6D3F0C2C-E441-42CA-96B2-D553E77373FF@law.du.edu> <680F06B3E36D42368C836297BBAE3E90@LeroyPC> <1047209402.239051.1485523721454@mail.yahoo.com> Message-ID: <689303FD-E299-46A8-B018-7F0FCA6D85D1@wi.rr.com> Historically solar minimums have been a time of reflection and introspection.

A used staple was caught in the speaker grill. Once I removed the staple, the audio was perfect. This incident reminded me of my old BlackBerry. One day a paper clip was stuck to it.

It was maddening. I never knew if the rig was going to turn on. It was always necessary to restart my computer to get my K3/100 to talk to the app that resets the firmware. I had several suggestions to fix the problem. The one that proved most helpful was to get a different power supply. I was using a big Astron supply feeding into a Johnson power strip. Several devices ran off the power supply. It should have been able to supply plenty of power for everything because the other devices were low wattage users like a keyer. Anyway, I had a smaller Anstron device that was once used with a 2-Meter radio. It was fully capable of 100 watts. I hooked it up and the rig as a dedicated supply and it has worked perfectly ever since. You may have a different problem than me but that?s my story.

I have a 35A switcher that loafs along. As I never have both K3's transmitting at the same time I am not taxing the supply. W3FPR got me on the correct track.

The manual mentions a random wire antenna with a counterpoise and recommends #26 ?Silky? from The Wireman (catalog #534). After obtaining 100 feet the first question is how long? Obviously I want it to tune 1:1 SWR, 80 to 10 meters but a quick search of the archives and manual came up dry for specific random wire lengths. So I cut 29 feet x 2 and boom - no joy. The 5MHz band got no better than 4:1 SWR and 80 meters was, well, hopeless. The rest was good. Ok searching the net the best I could find was http://www.hamuniverse.com/randomwireantennalengths.html with the magic number lengths: *29 35.5 41 58 71 84 107 119 148 203 347 407 423*. Still, no guarantee which would meet requirements on the KX2/KXAT2. So, after a splice and another cut, I can now officially announce that a 58 foot "random" wire with a 29 foot counterpoise will give a 1:1 SWR on all bands 80-10 on the KX2 using the KXAT2. :-) From frantz at pwpconsult.com Sat Jan 28 16:51:15 2017 From: frantz at pwpconsult.com (Bill Frantz) Date: Sat, 28 Jan 2017 13:51:15 -0800 Subject: [Elecraft] K3 - stuck at MCU LD we upgrading software In-Reply-To: Message-ID: On 1/28/17 at 12:49 PM, jimmy.walker at outlook.com (James Walker) wrote: >I did check the voltage reading on the K3/100 and it did reduce >severely under any load, even QRP.

What upgrades should I get? In-Reply-To: Message-ID: Andy, congratulations on your new radio. I would operate it as you receive it for a while while deciding what upgrades you might need. The 400 Hz filter is popular for CW, so I would see if it is satisfactory for your operating needs. The 100W upgrade is easy to install, but do you need an internal tuner? The new synth is a definite improvement, but if you aren't working in crowded conditions (DX pileups or contests), the old one is not bad. If you are thinking about some particular upgrade, ask here and you will get a lot of advice, sometimes contradictory. 73 Bill AE6JV On 1/28/17 at 5:20 PM, abullington at comcast.net wrote: >Years ago I built a nice K2/100 which I still have and love but >I saw a K3/10 for sale this morning on QRZ and bought it.

Some folks like the internal ATU but I don't have it since I use a resonant antenna or a remote ATU. I think the new synth improves weak signal receive.

I promised to let you folks know what I came up with on my friends KX3, KXPA100, and the R9 vertical. He got the KX3, KXPA100, and KPA500 back from Elecraft all repaired. I put the station together and this time set all 120 frequency-SWR memories at the 20 watt level. They all set up OK and at that point we went to lunch feeling good that all the problems were gone. We came back and started using the KPA500 on various frequencies. Any frequency we tried from 20 meters to 6 meters worked just fine at the 500 watt level. On 40 meters any power over 400 watts would give a fault on every piece of equipment (KAT500, KPA500, KXPA100 and an ANT ERR on the KX3. On 80 meters the faults would come on at anything over 300 watts. I felt the faults were quite violent so that more than likely explains how all three pieces of equipment got destroyed. I studied the R9 which I put together last fall. On 17 meters through 6 meters there are stubs for each band and no loading coils involved. On 20 meters there is a trap so again no loading coils. On 40 meters there is a trap and a loading coil and on 80 meters there is another trap and loading coil. I noticed on 40 and 80 I could get them to tune to low SWR with the KAT500 but if I started sending my call the KPA500 would start showing more power and soon go into the violent fault. Years ago I had a hustler vertical that would change the matched frequency as the coil heated up and I think this R9 is doing the same thing. Our solution is to run no more than 400 watts on 40 meters and no more than 300 watts on 80 meters. The specs for the R9 say it can handle 1500 watts and I suspect it can on the higher bands but at least this antenna can not on 40 or 80 meters. I came home and tried my camping KX3 and KXPA100 with my KAT500 and Hy-Gain HY-Tower vertical and it seems to work well in any of the memory position which I earlier set with my K3S and KPA500 so I feel we have isolated the problem to the R9 my friend is using. If anyone is able to use an R9 at higher power on 80 or 40 please get back to me and let me know how you are doing it. To everyone else thank you for the band width and suggestions. I consider this closed. 73 Ken W0CZ w0cz at i29.net Sent from my iPad > On Jan 25, 2017, at 1:45 PM, Kenneth Christiansen wrote: > > Hi to the group > > I have a friend with the following equipment. > KX3 with built in tuner. > KXPA100 with built in tuner. > KPA500 > KAT500 > 50 ft of LMR400 coax > R9 vertical. > The KPA500 is not in the circuit at this time. > We try to tune the KPA500 using the station set for 20 watts and a hand key. > The KXPA100 often kicks out.

What upgrades should I get? In-Reply-To: References: Message-ID: <05def72a-ead2-1782-2002-566a111b66e5@embarqmail.com> Andy, Congratulations on your purchase. As far as options go, first look at your antenna - if you have all resonant antennas, you do not need the tuner, but if you use a tuner, get the KAT3A - or if you plan on the KPA500 later, get the KAT500 instead. Next consider your operating desires. If you will be doing SWLING, get the KBPF3. If you want coverage down to 100kHz, you will need both the KBPF3 and the new synthesizer. There is also a capacitor that should be added when upgrading to the new synthesizer for coverage down to 100kHz. If you do DXing, where you are operating split often, get the subreceiver. If you order the subRX, a new synthesizer comes with it, so you will need to upgrade the synthesizer in your K3. Doing voice operation, especially contests? You may want the DVR option. As far as filters go, operate with the filters you have until you can decide if additional roofing filters are wanted. Remember that these are roofing filters and not the final filters - the DSP in the K3 provides the final filtering, and its bandwidth has nothing to do with the roofing filters. If you have the subRX and want to do much diversity receive, you should match the filters in the SubRX and the mainRX for best results. Remember that you do not have to add everything at once. Operate it for a while to decide if you want the capability afforded by the added options. 73, Don W3FPR On 1/28/2017 8:20 PM, abullington at comcast.net wrote: > Years ago I built a nice K2/100 which I still have and love but I saw a K3/10 for sale this morning on QRZ and bought it.

Compare the voltage directly at your power supply terminals between receive and transmit. If it stays up, then check your power cable to the K3 for adequate size wire and good connections. If you have a DC power distribution device like the RigRunner, remove the K3 from it and connect direct from the power supply to the K3. OTOH, if the voltage at the terminals droops during transmit, open the power supply cover and remove the bolt terminals - clean the solder lugs on the inside and the bolts, then reassemble making certain the bolts are tight. If those bolts turn even a little bit when tightening the external bolts, they are not tight. You must have tight connections at the power supply. 73, Don W3FPR On 1/28/2017 3:49 PM, James Walker wrote: > Yours is not the Astron power supply I was using.

The weak signal performance was much better than my original IC-756 rig. I did not install the automatic antenna tuner. I have continued to download the software changes since then. Two years ago I installed the general coverage receiver modification. I thought it was my imagination at the time but I thought had experienced a slight decrease in the primary and secondary receiver sensitivity. Today I put my Kenwood TS-480 that I had been using as a mobile in the shack. I was listing to a couple of weak strength SSB QSOs using the K3. Out of curiosity I switched over to the TS-480 and was surprised that the weak signals were more "copy-able" on the inexpensive Kenwood than on the K3. Does this indicate a problem with the RX in the K3 or is the apparent difference in the TS-480 RF gain come at the price of the definitely poorer adjacent signal rejection?

My R8 (same box) had an arc when using high power where the wire was attached to one of the toroids. I stuck a piece of polystyrene between the wire and the toroid to fix it. You might have to unsolder the board from its connections to get it out of the box in order to see and fix this. In my case it only occurred on 40m so it could be the same problem. 73, Vic, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 29 Jan 2017 05:06, Kenneth Christiansen wrote: > Hi to the group. > > I promised to let you folks know what I came up with on my friends > KX3, KXPA100, and the R9 vertical. > > He got the KX3, KXPA100, and KPA500 back from Elecraft all repaired. > > I put the station together and this time set all 120 frequency-SWR > memories at the 20 watt level.

What upgrades should I get? Andy, Congratulations on your purchase. As far as options go, first look at your antenna - if you have all resonant antennas, you do not need the tuner, but if you use a tuner, get the KAT3A - or if you plan on the KPA500 later, get the KAT500 instead. Next consider your operating desires. If you will be doing SWLING, get the KBPF3. If you want coverage down to 100kHz, you will need both the KBPF3 and the new synthesizer. There is also a capacitor that should be added when upgrading to the new synthesizer for coverage down to 100kHz. If you do DXing, where you are operating split often, get the subreceiver. If you order the subRX, a new synthesizer comes with it, so you will need to upgrade the synthesizer in your K3. Doing voice operation, especially contests? You may want the DVR option. As far as filters go, operate with the filters you have until you can decide if additional roofing filters are wanted. Remember that these are roofing filters and not the final filters - the DSP in the K3 provides the final filtering, and its bandwidth has nothing to do with the roofing filters. If you have the subRX and want to do much diversity receive, you should match the filters in the SubRX and the mainRX for best results. Remember that you do not have to add everything at once. Operate it for a while to decide if you want the capability afforded by the added options. 73, Don W3FPR On 1/28/2017 8:20 PM, abullington at comcast.net wrote: > Years ago I built a nice K2/100 which I still have and love but I saw a > K3/10 for sale this morning on QRZ and bought it.

In-Reply-To: References: Message-ID: <018601d27a3e$c155ea80$4401bf80$@kh-translation.dk> Dear Andy, I agree with Bill " The 400 Hz filter is popular for CW, so I would see if it is satisfactory for your operating needs. The 100W upgrade is easy to install, but do you need an internal tuner? The new synth is a definite improvement, but if you aren't working in crowded conditions (DX pileups or contests), the old one is not bad." If you want to operate without a computer the P3 will be interesting. I had a computer and four monitors already so I went with LP2 and CW Skimmer. This combination has been very helpful in DX pile ups (and monitoring the DX window on any band) - you are 95% CW op I remember.

I have the same supply, sans meters. The meter on the power supply is reading internal to the supply. Check on the outside with your DMM. The terminals on that supply are bolts with the heads on the inside. Those bolt heads apply pressure to the solder lugs on the inside. If the nuts on the outside (the ones closest to the enclosure) are not tight, there will be considerable voltage drop during transmit. The connections made on the outside must also be tight to assure a low resistance. It is a simple matter to connect your DMM and monitor the voltage as you transmit. 73, Don W3FPR On 1/29/2017 9:57 AM, James Walker wrote: > I tried the direct wiring fix first.

Thanks for this info. I'm preparing to take my new KX3 to the Dominican Republic next month for a QRP deployment on the beach at a resort. I'm planning to do WSPR, JT65, PSK31 and PHONE. I've not kept up my CW so I'm hoping to try some fldigi assisted CW contacts although it doesn't seem to copy human sent code very well so we'll see how that goes. I've tried a couple of other (Phone only) Caribbean QRP deployments when I had my FT817 and ATAS 25. 3 years ago in Panama it was winter field day and 10m was open so I created a pileup. It was a blast and I was bitten by the bug! (If you search ve3bwp QRP Costa Rica on YouTube you can see a few of the reactions I got - intrigued, the hotel staff kept the Marquita's flowing so I may sound a bit tipsy). Then last year I tried It from Panama. Didn't_make_a_single_contact! Heard lots but no-one heard me. I realized how ill prepared I was and relying on a compromise antenna near a solar minimum (with no CW or digimodes) would be even that close to the equator. So this year with a new KX3 and my wife's super thin MacBook life I'm going getting serious and I have a proper antenna! I've started reading through the Elecraft message archives trying to find all random wire success stories. I got some of the Wireman silky wire and now in search of what lengths to try. I saw Wayne's recommendation for 25ft for 40-6m so I've cut some for that. I'm looking to precut a few different lengths to try for various band combinations. Maybe even some band specific resonant ones for 20 to 10m so if anyone has some tried and true lengths for those I would appreciate hearing about actual lengths. This will be my first time with end feds or random wires. I'm also giving serious thought to packing my CrankIR as it can be made resonant very easily but it's 13.5lbs and would be the heaviest and bulkiest item of all. I may take it though just in case since it is comparable in performance to my base dipole. With it I've had regular phone ragchews at 5w with many assuming I was running way more power. Anyway if others have has similar ambitions/successes... would love to hear about it.

When I do those ?portable? operations I use an end-fed vertical that I came across at the web site of EARC - the Emergency Amateur Radio Club in Honolulu. URL below. Very simple antenna - is uses a 30 or so length of wire strung vertically and a 9:1 un-un. I homebrewed the un-un - piece of cake. While it isn?t the same as a super long wire antenna up 80 feet, it does pretty darn well. In fact, I will be taking my KX3 (barefoot) and this antenna on a three week vacation this spring to the southern Philippines - Mindanao. No (or very little) SSB, but primarily CW and possibly digital modes. Easy to build or cheap to buy, lightweight to transport, and performs very well...

I've started reading through the Elecraft message archives trying to find all random wire success stories. I got some of the Wireman silky wire and now in search of what lengths to try. I saw Wayne's recommendation for 25ft for 40-6m so I've cut some for that. I'm looking to precut a few different lengths to try for various band combinations. Maybe even some band specific resonant ones for 20 to 10m so if anyone has some tried and true lengths for those I would appreciate hearing about actual lengths. This will be my first time with end feds or random wires. I'm also giving serious thought to packing my CrankIR as it can be made resonant very easily but it's 13.5lbs and would be the heaviest and bulkiest item of all. I may take it though just in case since it is comparable in performance to my base dipole.

It is really a K3S-. It doesn't have the USB I/O board but has the rest of the K3 -> K3S upgrades. There general coverage bandpass filter board is installed. Here are the results on 20-6M. The sensitivities are as expected and comparable to other rigs' published results. They also seem to agree reasonably well with more well equipped lab K3 results. I don't claim well equipped lab accuracy. Condx: 1) SubRX off, attenuator off 2) CW mode 3) 400 Hz filter in 4) Measured the S/N with Spectrogram. These numbers are based upon a 10 db S/N ratio. That also happens to be the MDS I can hear +/- a few dB. On the 12,10,6M bands a 20 db S/N was measured and then subtracted 10 dB from the result. This is to eliminate possible signal generator leakage effects. The K3 audio output is very linear with RF signal level input so this is a reasonable thing to do. BAND no preamp preamp1 preamp2 20 -144 dBm -147 x 17 -143 -145 x 15 -143 -147 x 12 -144 -144 -154 10 -143 -145 -156 6 -136 -141 -151 I'm not sure I believe the -15x numbers. Elecraft does say preamp 2 is ultra low noise. Measurement setup: HP-8657B signal generator with additional internal shielding. 20 db attenuator at the generator output. double shielded RG-400 coax to K3 antenna. HP-8657B output verified with an HP-3586C up to 30 MHz down to -122 dBm. Spectrogram on a Delta 44 sound card to measure S/N. Signal measured from K3 line out. YMMV 73 de Brian/K3KO P.S. Switching in the second RX reduces these numbers about 3 dB. On 1/29/2017 3:55 AM, jay Miller wrote: > I assembled my K3/100 with the second receiver in December of 2010.

(Apologies to linguistic purists.) A simplified definition might be: A. long enough to work within the maximum limits of the ATU's L-network on the lowest band used B. presents a reasonably low impedance on all bands used (e.g., doesn't look like an end-fed half-wave) ATUs have limited monotonicity and granularity, as well as stray impedances, so in practice there is a third criteria: C. tunable on each band used despite specific L-network idiosyncrasies This third criteria is the hardest one to predict for a given ATU design, as the idiosyncrasies vary with PCB layout and actual component values. They may only impact the highest bands, or for a particular antenna, the bands on which Q is the highest. For our ATU designs, we try to minimize strays and keep the network monotonic by using tightly toleranced capacitors and toroidal inductors. While a wide range of wire lengths will meet the requirements of a "KRA" in the field, we've found from experience that something in the 25'-28' range works on all bands from 40 meters up, and roughly twice this for 80 meters up. Since it's impossible to predict the effect of ground losses, obstructions, deployed wire angles, etc., you may occasionally need to add or remove wire to obtain resonance on all bands used. 73, Wayne N6KR On Jan 29, 2017, at 7:55 AM, Tom McCulloch wrote: > I guess we need an alternate definition of "random" ;-) > > Tom > > wb2qdg From pincon at erols.com Sun Jan 29 12:53:50 2017 From: pincon at erols.com (Charlie T, K3ICH) Date: Sun, 29 Jan 2017 12:53:50 -0500 Subject: [Elecraft] Random wire lengths for antennas In-Reply-To: <003801d27a4a$a74c9bf0$f5e5d3d0$@gamewood.net> References: <5620c49a-82c3-f1c7-cfe2-d3546a4f03cb@roadrunner.com> <1B22FB79-D09C-44FD-88FB-196138912569@liberty.edu> <003801d27a4a$a74c9bf0$f5e5d3d0$@gamewood.net> Message-ID: <007f01d27a58$a94b70d0$fbe25270$@erols.com> OK, How about only Two types, by definition: #1 EFHW (End Fed ?? resonant wire) #2 NRW (Non-Resonant wire) Chas -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ken Talbott Sent: Sunday, January 29, 2017 11:14 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Random wire lengths for antennas Indeed we do.

This will match (and work reasonably well) from 80m through 10m as it is not close to a multiple of a half wave on any of the ham bands so it presents a reasonable impedance that can be matched by an autotuner.

In very simple terms, if you can load it, it will radiate. That was a position that a writer with the nom de plume of Kurt N Sterba too in a book he wrote. By the physical law of conservation of energy, it all has to go somewhere. And, that could be heat or radiation. In his book he claims to have loaded a shopping cart and talked to people. Yes, you can do these things as long as you make good connections and the tuners can handle it. All of the discussion is how to pick a length that the tuner will accept. Once there, physics takes over. And just to prove my point, and yours, I just worked the CQ 160 CW contest. My antenna was a vertical 20 meter dipole center fed with open wire. My radio is a K3s. I worked across this country, Canada, and some DX with this 33' wire antenna that by all rights should have been over 200'. I would have done better, but my local power company added another handicap, line noise. Bottom line: Throw some wire up and see if it can be loaded.

The fifteen feet of coax to the balun is low-loss LMR400. The low-loss coax helps with the high SWR problem, in that the losses are minimized (for what I can afford, that is). This antenna loads up fine on all bands except 6m. I won't claim it's ultra-efficient, but at least the ATU can handle it. I chose the length of the ladder line as 61 feet, and this seems to give good results. I'm sure other lengths could be calculated that would work equally well. 73, matt W6NIA On 1/29/2017 10:17 AM, Wayne Burdick wrote: > I'd call an ad-hoc antenna that works on multiple bands with an ATU a "Kinda-Random Antenna" (KRA).

I took it apart today and found that although the connection between the power leads and the bolts was tight, the connection between the bolt and the housing of the power supply had worked a bit loose over the years. I took things apart and tightened the connection between the case and the bolt. It is all back together and working fine. I also have a direct connection between the PS and the K3 using thicker wire. The K3 is working fine right now. In the past I suffered loss of transmit power although RX was fine. I don?t remember the error message but I think it was ERR DSP. With every failure reloading the firmware and calibrating power cleared it up. The information I had was that this error can be associated with erratic power supply issues.

Compare the voltage directly at your power supply terminals between receive and transmit. If it stays up, then check your power cable to the K3 for adequate size wire and good connections. If you have a DC power distribution device like the RigRunner, remove the K3 from it and connect direct from the power supply to the K3. OTOH, if the voltage at the terminals droops during transmit, open the power supply cover and remove the bolt terminals - clean the solder lugs on the inside and the bolts, then reassemble making certain the bolts are tight. If those bolts turn even a little bit when tightening the external bolts, they are not tight. You must have tight connections at the power supply. 73, Don W3FPR On 1/28/2017 3:49 PM, James Walker wrote: > Yours is not the Astron power supply I was using.

The point of failure is paint between the chassis and the mounting lug of the terminal strip where the green wire is soldered. One of those supplies, which I still own as a backup, has paint between the two "clam-shell" sections of the chassis that prevents their making contact, thus defeating shielding. Early Elecraft products had this problem, but newer ones do not. Those building kits will remember paint-protecting tape that must be removed at points where the sections of the chassis mate. 73, Jim K9YC On Sun,1/29/2017 10:49 AM, George Thornton wrote: > I took it apart today and found that although the connection between the power leads and the bolts was tight, the connection between the bolt and the housing of the power supply had worked a bit loose over the years.

They are way better than those measured by ARRL and Sherwood and some are a physical impossibility. The thermal noise floor (kTB) at 400Hz is -148dBm so any number at or below this is physically impossible. To me it looks like all your numbers are off by 10dB or so for whatever reason. I am not sure how you used Spectrogram to measure SNR. All you really need is the dBV meter built into the K3. Assuming it's well designed it should be ideal for measuring RMS power ratios which is what you need. The manual sheets for the XG3 generator from Elecraft has excellent instructions on how to calculate MDS using nothing more than the XG3 and the K3 itself. Of course replacing the XG3 with a professional grade HP generator will not hurt the accuracy of the results. Anyway, this doesn't really explain why you think the K3 has lost sensitivity since the installation of the general coverage bandpass filter board. When I installed mine, I noticed no such effect. If anything this filter ought to have lower loss than the per band RF filters used for in ham-band reception.

If the wire is near 1/2 wavelength on a band, the impedance at the end will be very high, and the tuner may not be able to match it. In truth, we're really talking about non-resonant antennas, so numbers like 53' keep coming up. It was easier before 60m and 30m and 17m and 12m because all of the ham bands were harmonically related, and the math was simpler. 73 -- Lynn On 1/29/2017 7:55 AM, Tom McCulloch wrote: > I guess we need an alternate definition of "random" ;-) > > Tom > > wb2qdg From ve3bwp at gmail.com Sun Jan 29 16:18:18 2017 From: ve3bwp at gmail.com (Brian ve3bwp Pietrzyk) Date: Sun, 29 Jan 2017 16:18:18 -0500 Subject: [Elecraft] KXAT2: Recommended Random Wire Lengths In-Reply-To: <789BF945-C411-4E73-AB9F-A11E22D8F054@me.com> References: <789BF945-C411-4E73-AB9F-A11E22D8F054@me.com> Message-ID: Hi Jim, Thanks for this. Lol, I worked for HP and spent a lot of time in Roseville in your ?winter? months. Our current winter weather limits outside antenna experimentation for the very ambitious or a desperate ?wire down? situation. I too was giving serious thought to a vertical wire on a telescoping pole just as you describe and leaving the CrankIR home. Seeing a local ham who has become well practiced with QRP CW/digimode field deployments has the MFJ telescoping pole to hold up an end fed wire in an inverted vee with a home brew 9:1 and a LDG Z100 tuner. He?s quite happy with it so this is definitely on my list of things to try. I seem to remember hearing the design intent of the KX2/KX3 ATU?s were such that a 9:1 Balun is not required. I think I was told that in person by one of the Elecraft principles at Dayton then read it somewhere as well. Unfortunately I?ve not put that to the test myself but I may just brave the cold before the trip long enough to test it out. So I guess a good question is...does the 9:1 balun produce better results then simply connecting direct to a KX2/3 ATU? Since I?ve usually been able to build or buy resonant antennas over the years so I must confess I?ve not had that much experience with tuners..other then using a friends summer cottage G5RV or touching up the band edges of a narrower antenna. For the trip I expect never to go lower in frequency then 40meters given the southern latitude and I?ll only be operating between lunch and supper barefoot (in bare feet) one or two afternoons max. The your trip to the Philippines sound exciting! You have to let us know when you are there set up so we can try and work you.

I saw Wayne's recommendation for 25ft for 40-6m so I've cut some for that. I'm looking to precut a few different lengths to try for various band combinations. Maybe even some band specific resonant ones for 20 to 10m so if anyone has some tried and true lengths for those I would appreciate hearing about actual lengths.

Since the ATU can't match the high impedance of a half wave multiple, the lower impedance of the wire will lead to larger ground/counterpoise currents. Even with a decent ground and/or counterpoise, some power is lost, and at 100 W or above, you might need to keep you fingers off the metal stuff. That said, it can be a simple, effective way to get on the air. I've long been a fan of the EFHW, but I've always used an external tuner. The impedance should be somewhere in the 1K-5K range. An internal ATU might be able to match that with an external transformer, say with a 3:1 turns ratio, though I'm not sure one could make such a transformer with low enough stray capacitance to work on the higher bands.

A quick heuristic to help understand. The current at the far end of a random wire is zero. One-quarter wavelength from the far end, the current is maximum. Another one-quarter wavelength along (total of one-half wavelength from far end) the current is zero. I = E / Z >> Z = E / I So, one-half wavelength from the far end, Z is going to be whatever E is divided by a very small number >> VERY HIGH and hard to match. This also explains why the impedance at the center of a half-wave dipole is reasonable. Current at either end of the dipole is zero and high at the center. Voltage at either end of the dipole is high and low at the center. Z = E / I At half-wave dipole center, low voltage at center divided by high current at center gives a low impedance, easy to match.

The lower power circuits are protected by a resettable fuse. So the K3 is capable of protecting itself from overcurrent. That being said, there is always the danger of a short or other fault in the DC wiring that can cause excessive current in the power wire which can spew molten metal around causing injury to anyone nearby or starting fires. IMHO, any power supply that does not have overcurrent protection should have a fuse located near the power source - that is especially true of batteries which can source an enormous amount of current. That fuse near the power supply is not necessarily for protection of the equipment, but rather it is for protection of your home and family. 73, Don W3FPR On 1/29/2017 5:31 PM, Tom wrote: > Thanks Ron.

He called it "The Illuminator." Kurt N. Sterba [a regular in the old WorldRadio] is correct, the power will go somewhere. My home antenna is a 136' wire strung along the wood fence on electric fence insulators. Fed at the end, no overt counterpoise [the outside of the coax shield handles that]. Not spec'd for 160 but the KAT3 matches it fine. Invisible to HOA. NVIS on 160 and 80, semi-NVIS on 40. One thing to remember: feeding electrically long wires results in complicated radiation patterns. The higher in frequency you go, the more it's going to squirt your RF in different directions, not all of which point at the DX. But, mine works very well considering it's about 1.8 m off the ground. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/29/2017 10:26 AM, Barry wrote: > Wayne, > I know what you are saying and agree.

For #10 wire, fuse at 30 amps, for #12 wire, fuse at 20 amps. Note that this recommendation has nothing to do with the current draw of the equipment, only with the wire size. I fuse #16 wire at 10 amps and #18 at 7 or 5 amps both in the shack and at the workbench. I do not use anything smaller than #18 wire on power cables. As I indicated, this has nothing to do with the current draw and protection of the connected equipment - it is only a consideration for the wire size. If you compare it to household wiring and circuit breakers in your electrical panel, you will see a parallel. #10 wire, use a 30 amp breaker, #12 wire, use a 20 amp breaker, #14 wire use a 15 amp breaker. It is the same thing at DC - fuse at the power source for the wire size. If the equipment needs a smaller fuse than that afforded by the fuse at the power supply, add an additional fuse or circuit breaker at the equipment end. It is common to see equipment using AC power lines protected by a fuse in the equipment cabinet, and it will be at a lesser rating than the rating of the wiring - that latter fuse is to protect the equipment, not the wiring - two different "animals" - safety to home and personnel vs. protection for the equipment. As far as fusing both the positive and negative leads, that is controversial and depends on how the negative is wired. It goes back to mobile installations where if the negative is connected directly to the battery and a fault in the vehicle grounding system should fail, then the fuse in the negative will protect the equipment. However, the better solution is to connect the mobile radio negative solidly to the chassis (near the radio) and fuse only the positive side. Ask any professional installer of mobile radios how it should be done, and they generally agree that the negative should connect to the chassis near the radio, and not be routed all the way to the battery negative (where it would need a fuse). 73, Don W3FPR 73, Don W3FPR On 1/29/2017 6:03 PM, Tom wrote: > Thanks Don.

I have the power cable to the K3 fused on both leads using automobile-type blade fuse holders wired into Power Pole connectors at both ends. The low power accessories like the P3, PR6-10, remote antenna switch, etc. are individually fused on their positive sides. What I don?t want is to have an accessory develop a problem and take out the main rig when its fuse blows. In accordance with Murphy?s Law that will happen when a P5 is working a pileup and I?m next.

I gotta try that one sometime. Kurt N. Sterba was correct. Textbook antennas aren't always possible, or even needed. If the situation is difficult, any radiator is better than none. However, hams in general are anal animals on the subject of antennas. My attitude has always been what's a db or two among friends, and quite often that is the number we are sweating. But, if you can't make it exactly like Kraus writes, get as close as you can and let your antenna tuner worry about the match and don't think about that extra db. 73, Barry K3NDM ------ Original Message ------ From: "Fred Jensen" To: elecraft at mailman.qth.net Sent: 1/29/2017 6:10:29 PM Subject: Re: [Elecraft] The "Kinda Random Antenna" >N6BT famously set up a "phased array" of 3 light bulbs in a V-beam >configuration and achieved WAC.

Most of us O.T.s (like you) have had the experience of using a 'grocery store dummy load' (ordinary incandescent light bulb) to test our rigs and had someone call us in return! Another thing to remember is that there is no direction in which an antenna does not radiate.

My home antenna is a 136' wire strung along the wood fence on electric fence insulators. Fed at the end, no overt counterpoise [the outside of the coax shield handles that]. Not spec'd for 160 but the KAT3 matches it fine. Invisible to HOA. NVIS on 160 and 80, semi-NVIS on 40. One thing to remember: feeding electrically long wires results in complicated radiation patterns. The higher in frequency you go, the more it's going to squirt your RF in different directions, not all of which point at the DX.

I have a L-net tuner (a circuit like in the Elecraft ATUs) consisting of a large ceramic roller inductor and a "transmitting" type variable (0.3" plate spacing) that I use with my Inverted L. It works beautifully on all bands, even where the impedance is so high a neon bulb on the shelf near the tuner flashes when I transmit. Compressing a tuner enough to fit inside of an amp or a K3 means compromising on what sort of voltages can be tolerated. That is why you can't get too close to 1/2 wavelength, even though 1/2 wavelength is where the antenna will be the most efficient. Engineering is always a tradeoff. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Lynn W.

If the wire is near 1/2 wavelength on a band, the impedance at the end will be very high, and the tuner may not be able to match it. In truth, we're really talking about non-resonant antennas, so numbers like 53' keep coming up. It was easier before 60m and 30m and 17m and 12m because all of the ham bands were harmonically related, and the math was simpler. 73 -- Lynn On 1/29/2017 7:55 AM, Tom McCulloch wrote: > I guess we need an alternate definition of "random" ;-) > > Tom > > wb2qdg ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ron at elecraft.com From dean.k2ww at gmail.com Sun Jan 29 22:50:48 2017 From: dean.k2ww at gmail.com (Dean L) Date: Sun, 29 Jan 2017 22:50:48 -0500 Subject: [Elecraft] Random wire lengths for antennas In-Reply-To: <9106254F-ECC6-434D-9AD9-8873538BF213@widomaker.com> References: <5620c49a-82c3-f1c7-cfe2-d3546a4f03cb@roadrunner.com> <1B22FB79-D09C-44FD-88FB-196138912569@liberty.edu> <003801d27a4a$a74c9bf0$f5e5d3d0$@gamewood.net> <007f01d27a58$a94b70d0$fbe25270$@erols.com> <9106254F-ECC6-434D-9AD9-8873538BF213@widomaker.com> Message-ID: I believe that is why Jeff, kg7hdz, provided a link to an excel chart that has lengths of NO half waves in US ham bands.

(Doesn?t look like the router itself can be an endpoint though, you'd need some PC or Raspberry Pi at the remote site for that.) Anyway. Find out how to backup and restore the router's configuration to a file on a PC, and make that backup. Then the next time you have to change it (due to lightning strike?) You can just load the known working config into the new router, and likely you are ready to go. (Page 55 of the user manual.) Also. With new out the box routers, check if there is updated firmware available from the makers. Often the things come out of the factory (wherever) with very old/early firmware in, that has known issues. Cisco are no exception to that sadly. (Linksys in disguise!) Make sure you get the correct firmware, that product has two versions of hardware it seems. I've not checked, but "OpenWRT" or "Tomato" alternative firmware's might run on that device. That can often give you "a lot" more functionality, if you need it, such as VPN endpoints! Oh, and make sure any UPnP functionality is not exposed to the www. grc.com/shieldsup will test that for you... (If you connect via the new router.) 73 and Enjoy. Dave G0WBX.

And the charging supply is set to 14.5 V. So the BAT ERR may be from being full charged, or a bad connection somewhere. I pulled the charger board, unplugged the connector, checked that both sets of contacts showed proper voltage then plugged it back in, then plugged charger board back in. Guess I should have included that in original post. Time to call the guys at Elecraft I guess.

If the cells are healthy and are truly low self discharge NiMH cells, they should not deplete much over a period of a few weeks or even months, even taking real time clock current into account. For example, my 4 year old Eneloop 2000 cells haven't been recharged for well over 8 months.? The radio has been sitting in my day pack, ready to go, for all of that time, with a weekly power on cycle using battery power to be sure everything is OK.? I just did that again this morning and the battery voltage readout says 9.4 volts.? I suspect most of that discharge was from those occasional power on cycles since I sometimes check it out by transmitting on several bands. The real-time clock does, however, gain a lot of time during that period.? I can live with that.

I now keep the rig connected to the shack DC supply, even when it is not in use, just to prevent the demise of the cell's, but also of course keeps the clock running. Doesn?t need much current, probably a generic 14V wall wart would run the clock, and allow periodic battery top up if deemed necessary. 73. Dave G0WBX.

No problem matching anything using BL-1, BL-2, or any other 4:1 (or 9:1) balun although for odd impedances the balun may have substantial losses. But I prefer balun than antenna-tuner overheating. Probably all wire longer than 1/4 lambda radiate nearly all. Vertical above 5/8 lambda start generating high lobes. Horizontal add a few db because of ground reflections but also lobes. Once I made an experiment trying a vertical with a few radials, a random long wire with radials, or two random long wires as a semidipole, all fed by TV ribbon. In all cases, two random wires were the best, often by far, across bands. But setting up a portable vertical is easy, one long wire is hard, and 2 long wire is the hardest. In a nutshell, random wires are fine with exact length unimportant. If tuning problems, use a small balun.

I hope that the K3s and K3 panel sizes are the same - I don't know for sure. Here are the measurements for the K3s anyway: Left side panel - 3 hole centers for the 2m module are 3.245", 5.175", and 4.775" from the front edge of the panel, and they are all 0.655" down from the top edge of the panel. ANT3 BNC connector (2m ANT) hole center on fan panel is 0.460" from the left side of the fan panel (as you look at the rear of the rig) and 0.900" down from the top edge of the fan panel. Cut-out in the top rail starts 0.425" from the outside surface of the left-hand end of the rail and ends at 3.375" from the same reference point. Hope this helps!

G4GNX Sent: Monday, January 30, 2017 2:23 PM To: Elecraft Reflector Subject: [Elecraft] Help with dimensions please I bought a K144XV internal 2 metre transverter for my K3, from another amateur in the US and unfortunately he?s sent me the wrong panels and stiffener and it just ain?t worth trying to return them from UK to USA for exchange. Unfortunately the cost of new parts from Elecraft is out of proportion with the purchase (expensive) so I want to modify the panels he?s sent. Unfortunately Elecraft don?t have a published template. Can someone help me out with the placement of the 3 fixing holes for the K144XV in the LH side panel, the placement of the 2 metre Ant socket hole in the fan panel and possibly the start and end of the cut-out in the cross panel stiffener. Obviously I need the measurements to be very accurate, but I could probably manage with the placement of just one of the holes in the side panel (I can work the rest out from the K144XV side panel) and the hole placement in the fan panel. I don?t need the actual size of the holes, just distances to centres. Thanks in advance. 73, Alan.

I have 2.8 kHz filters in the main receiver in both of my K3s. I like them because they're a bit flatter in the passband, which reduces the incidental AM when I'm transmitting RTTY. The steeper skirts also do a bit better in the presence of strong signals. > I understand the 8 pole is a wider > filter with 3 more filtering crystals , does it make any difference in > received audio? Not that you would notice. > also could I use the fm filter for use in the am position. I'll let Don or Wayne answer that with respect to TX. I don't TX AM, but I sometimes tune down to the AM BC band to verify the directivity of my RX antennas. 73, Jim K9YC From donwilh at embarqmail.com Mon Jan 30 20:33:40 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 30 Jan 2017 20:33:40 -0500 Subject: [Elecraft] Filters In-Reply-To: <1485825698586-7626294.post@n2.nabble.com> References: <1485825698586-7626294.post@n2.nabble.com> Message-ID: <5bffd659-3a4d-2dad-9c59-794c5c7f897b@embarqmail.com> Mike, Unless you are doing SSB contesting, you will likely notice little difference between the 2.7kHz and the 2.8kHz filters. The skirts on the 2.8kHz filter are a bit steeper than for the 2.7kHz. If you have the subRX and want to do diversity receive, it would benefit you to use the 2.8kHz filter in both the mainRX and the subRX. Unless you have really critical ears, you will not notice a difference. Yes, you can use the 13kHz filter for AM. 73, Don W3FPR On 1/30/2017 8:21 PM, mtruss wrote: > I have purchased a used K3, serial number 3000 or so, it has been sent back > to Elecraft for updates etc and returned to me working great so far.

What is a McCoy Dipole? Named after Lew McCoy, it follows his rules of construction. "Make it as long as you can, get it as high as you can, and feed it with ladder-line." No math, no measurements, no sweat. But a TUNER (transmatch) is definitely needed. ? Emory Schley N4LP ? Kurt N. Sterba was correct. Textbook antennas aren't always possible, or even needed. If the situation is difficult, any radiator is better than none. However, hams in general are anal animals on the subject of antennas. My attitude has always been what's a db or two among friends, and quite often that is the number we are sweating. But, if you can't make it exactly like Kraus writes, get as close as you can and let your antenna tuner worry about the match and don't think about that extra db. 73, Barry K3NDM ------ Original Message ------ From: "Fred Jensen" To: elecraft at mailman.qth.net Sent: 1/29/2017 6:10:29 PM Subject: Re: [Elecraft] The "Kinda Random Antenna" >N6BT famously set up a "phased array" of 3 light bulbs in a V-beam >configuration and achieved WAC.

You will not notice any difference going from the 2.8 KHz to 2.7 KHz filters. The ultimate bandwidth is determined by the DSP in the second (15 KHz) IF and the roofing filter skirts don't make much difference once they're down 30 - 40 dB. If you're into serious SSB contesting you may want to add either the 2.1 KHz or 1.8 KHz roofing filter for that additional protection from strong adjacent channel signals but in most cases the adjacent channel garbage is often transmitter IMD (splatter) that is actually "on channel" and can't be rejected by any filtering. > also could I use the fm filter for use in the am position. Yes, he FM filter (13 KHz) can be used for both AM transmit and receive. Note: even with the 13 KHz filter, the widest receive bandwidth will be 4.2 KHz - not 6+ KHz - as the receiver audio chain includes a sharp 4.25 KHz low pass "brick wall" audio filter to limit artifacts from the digital to analog converter. 73, ...

When thinking about filters for the K3 or K3S remember that they are roofing filters. The DSP code also filters the signal, so unless you have a problem with nearby strong signals, the DSP filtering may do everything you need. For example, when I find very close CW signals, I may dial the DSP width down to 50 or 100 Hz, which frequently eliminates the interference. On the other hand, during a contest when a local station is calling CQ 400 Hz up from the station I'm trying to work, the 250 Hz filter is very helpful. The FM filter can be used for AM operations. My filter configuration is: 13 KHz FM filter 2.7 KHz 5 pole filter 2.1 KHz 8 pole filter for SSB .25 KHz 8 pole filter for CW and digital operation I just let the radio pick the right filter as I change the DSP bandwidth. It all works very nicely during contests and DX chasing. 73 Bill AE6JV On 1/30/17 at 5:21 PM, mtruss8841 at comcast.net (mtruss) wrote: >I have purchased a used K3, serial number 3000 or so, it has been sent back >to Elecraft for updates etc and returned to me working great so far.

The total length of a center fed dipole is 1/2 wave, and that's the magic number. If you are operating at 14.300 and you're trying to end-feed a wire that is 32.7 feet long (same length as a dipole, but *not* fed at the middle), the impedance will be very high. Add 16.3 feet, and you won't be a half-wave, you'll be 3/4 wave long, and the impedance at the end should be well within the range of a good tuner. Double the length, and you're at a full wave, and it's the same impedance (more or less) as trying to end-feed a half-wave. Doesn't matter what you do, if your "randomly chosen" length turns out to be a multiple of one half wave on a frequency you want to use, then the stock tuner in most any radio is going to have trouble tuning it. 73 -- Lynn From ron at cobi.biz Mon Jan 30 21:54:51 2017 From: ron at cobi.biz (Ron D'Eau Claire) Date: Mon, 30 Jan 2017 18:54:51 -0800 Subject: [Elecraft] The "Kinda Random Antenna" In-Reply-To: References: <5620c49a-82c3-f1c7-cfe2-d3546a4f03cb@roadrunner.com> <1B22FB79-D09C-44FD-88FB-196138912569@liberty.edu> <3854BB1A-2FDD-4DBA-ABF2-BAFE3723EA24@elecraft.com> <11687a1e-d35e-06e9-edfb-c12cb015c7c5@foothill.net>, Message-ID: <000001d27b6d$652a2c00$2f7e8400$@biz> Yep, that is my favorite antenna for H.F. fed with open wire line and a balanced tuner.

The one that most comes to mind is height above ground. 160 meters can be a real problem. If it is a horizontal, the average ham antenna height of 35-50 feet is very, very low electrically. Two things would happen here. First, a lot of energy is being lost to ground, and second, the radiated signal will be at high angle. Remember, a quarter wave on 160 meters is on the order of 135 feet which is the point where you get maximum radiation straight up. At lower heights, gains upward goes down and doesn't fill in toward the horizon. The means electrically low antennas are not effective. The other area that comes to mind is the feed system itself. Not mentioned is whether open wire is being used. I would guess that the system SWR may be very high meaning losses on coax should be much greater than a 1 db. And, some tuners are not low loss when operated at their extremes. I get away with what I do ONLY because my 20 meter vertical antenna is less effected by being low, I feed it with ladder line which has low loss even at absurdly high SWRs, and the tuner I use is designed to be used with antennas that are no where near optimum. From what I did this weekend, I could surmise that my 33' radiator was radiating everything it received. If there is someone who really wants to do a math problem, I'll measure exactly the transmission line length, but I suspect that basically the about 60 feet of open wire helped. I would guess that the antenna reflected a very low impedance with a large reactive component, and the line length helped in translating the antenna impedance to something better handled by the tuner. Therefore, my losses are contained. 73, Barry K3NDM ------ Original Message ------ From: "Bill Johnson" To: "'Barry'" ; "'Emory Schley'" Cc: "elecraft at mailman.qth.net" Sent: 1/30/2017 9:42:35 PM Subject: RE: [Elecraft] The "Kinda Random Antenna" >OH YES, the headaches from looking at the formulas at this stage of >the >game.

For some bands the 9:1 "balun" (not used as a true balun in this case, since both the coax and the random wire are unbalanced by nature) will step the feedpoint impedance down to something that's a better match for the 50 ohm coax, limiting coax losses. It can also allow your ATU to tune up on frequencies otherwise outside its range. Use the "balun" with a counterpoise or earth. In some cases the 4:1 or 1:1 balun may be a better choice, or even connecting the wire directly to the coax center conductor (and counterpoise to the shield). All depends on QRG and wire length. If the ATU can tune it up, you're good to go, if not, change one or more parameters until it can (wire length, balun ratio, counterpoise length and orientation).

That's exactly what I need, thank you. The panel sizes of the new and old are exactly the same. I guess with the K144XV they just took the original panels and drilled the extra holes. It's possible that the very late K3s and K3Ss already have the holes drilled, but they're filled with screws and nuts, possibly a plug in the fan panel. My K3 is in the 2000s, so is far too early for that. I'll now print your dimensions for my archive and get drilling. :-) Many thanks again. 73, Alan.

Unless one is using a matching device designed as a current balun, the common 4:1 and 9:1 "baluns" are actually simple auto-transformers. The best approach is an auto-transformer at the feedpoint (with a counterpoise) followed by a true 1:1 current balun (common mode choke). The 9:1 "balun"/transformer may be more appropriate if the "wire" approaches a half wave on the frequencies of interest. However, there is a definite interaction among antenna length, transformer ratio, feedline impedance and feedline length. 73, ...

The 9:1 is generally an UNUN. When you run 100 watts or less most 1kw manufactured baluns or Ununs will take a wide variety of SWR if you are only running 100 watts. Because this thread is I believe about QRP the amount of power dissipated due to loss is not a factor. When you jump to 500 watts, core heating, saturation and breakdown are a risk. For instance, the W2AU balun that is manufactured as a center feed point for a dipole is only rated for the power at 1:1 SWR. In the printed literature the power rating drops off considerable as one goes to 2:1. I have personal experience with this particular balun when an 80/40 trap dipole was constructed using that balun and the Unadalla KW40 traps. Operating 40 was no problem as it was nearly 1:1 anywhere we operated [CW], but on 80 CW the bandwidth was much narrower, as to be expected and nearing the edges when we ran 500 watts into the antenna with the balun rated at 1kw, well, it's core heated up, SWR drastically changed, heating the core windings so much that the solder to the SO239 connecting the core to the coax melted off. We knew that the SWR was between 2.5-3:1 on the edges of the 80 meter range. So be careful. Additionally, I have little faith in stick Baluns or Ununs, I personally do not believe they are nearly as good as a Toroid constructed balun. Ununs seem to in my experience, tolerate wide ranges in SWR. I have used a 9:1 unun and their new 52:1 transformer for end fed antennas manufactured by Balundesigns.com with excellent results running 800 watts CW with little or no heating of the core and consistent results in a multiband environment. This was done using a 43, 53 and 87 foot end fed vertical/random wire/ inverted L and Half Square configurations. I have not modeled the pattern with NEC but I have compared it on Reverse Beacon Network [RBN] and I am definitely getting out. Full well knowing that Non resonant antennas are not as good as resonant ones, yes there is a difference in RBN reporting which favors the resonant, but, not always. This is because there is "funky lobe radiation" that can give a high report to just random one or two reporting stations and then the rest are 10-15 db less than the resonant over a wider area of report stations. This supports the pattern is not predictable, or as predictable as a resonant antenna installed correctly. Knowing we are addressing compromise installation for multiband usage, this I believe is acceptable. If you have goals of working or covering with gain and directivity, then there is no replacement for well designed and well installed resonant antennas. This is especially true in the competitive environment of contesting. When an antenna that is not balanced is used, the RF will seek a way to ground. Problems with feed line radiation, and RF in the shack are problematic. Using a counterpoise or limited radial system is recommended to provide the missing balance and a path to ground. This is generally not a problem at QRP levels but because a few 100 miliwatts of power coming back to the shack does not cause much problems but, jump that up to 10 or 100 watts and problems will surely make your life a living hell trying to keep the computer, keyboard, mouse cables connected and ATU from resetting and starting tuning cycle again and again. Best solution is to run resonant balanced antennas if one can, if one can't, invest in a few line isolators for the coax before it hits the shack and then have a good stock of Mix 31 ferrite beads for each cable in the shack, eg, usb, keyer, mic, speaker, keyboard, mouse...you get the idea. In the end, when one runs QRP power, balun/unun saturation and performance degradation, allows most anything to fly, jump the power to 100 watts, watch out, then to 800 watts...reforming injection formed plastic is in your future. Although, relative to this discussion, making an unun or balun with a T25 core and 32gauge wire will most likely produce the same disasterous results with 10 watts. LOL. Finally, Any antenna is better than No antenna.

I borrowed a KX3 from a friend when I went to visit family in FL a few years ago. I had a 9:1 "un-un", about 126' of wire, and 50 feet of RG8-X. I got the feedpoint, up 30 feet into a tree, and the far end over limb of another tree. That point was about 15 feet above ground. About 7 feed of the wire hung straight down toward the ground. I used a 30 foot counterpoise, that hung down from the "un-un", along with the coax. I did not try 160 (this was in mid-summer), but the ATU in the KX3 achieved a good enough match on 80 through 10 meters... and I made a few hundred QSOs, including some nice long rag chews, and 68 countries in just shy of 3 weeks. A couple of locals are using the same design as their primary antenna for 160 & 80 meters. I got my "un-un" from Balun Designs, and they also have a chart on their website with some suggested wire lengths.

I was not using 130' antenna, but one that was only 33'. And I was able to get out. Which leads to my second point. Some of us live in areas or on property that is not best suited for HF antennas, but so what. With a little thought, a bad situation can be made to work out pretty well. And lastly, throw something up and try it; you never know just what might happen. As an aside, I was surprised that I could load a 33' on 160, and more surprised when I was actually able to get out of my state; I live in Maryland. Morocco and Mexico where a shock. And, I will admit you can do things during contests that are nearly impossible at other times. Something to consider. Open wire was around almost as far back as Marconi, and maybe he used it. It has little loss even at high SWR, far, far less than coax in the extreme. In the olden days, no one really worried about SWR losses. Open wire was the common transmission line. Antenna tuners weren't really around, either.The trick that was done in those times was to have your final amplifier's tank circuit tune to the output frequency and act as the antenna coupler. In fact, the commercial station on Montauk Point at the tip of Long Island used to use rhombic antennas pointed toward Europe. The station engineer told me that the SWR was around 14:1 and he didn't worry too much about it as the loss on the line to his antenna was about 1 db and the a swinging link took care of the match. As hams in today's world, there are a few things that can be done to get out on HF. Putting up the biggest antenna with the most gain is at the top of the list. But, not everyone has the ability to do as some of my friends like W3LPL, for instance, are able to do. But, there is one thing that many hams overlook, cut the loss from your radio to the antenna. That means use the transmission line that has the least loss for the situation and make sure you can operate your antenna tuner, if needed, in a range that has its losses at a minimum. Do not worry about resonance. Most of us use antennas that if they were resonant wouldn't reflect 50 Ohms anyway. 73, Barry K3NDM ------ Original Message ------ From: "Ron D'Eau Claire" To: elecraft at mailman.qth.net Sent: 1/31/2017 11:53:49 AM Subject: Re: [Elecraft] The "Kinda Random Antenna" >The intrinsic higher impedance of ladder line helps reduce the losses >through a lower SWR than typical coax.

The word "balun" is a bastard -- it is widely used to describe nearly a dozen things that are VERY different from each other. W4TV got it right by adding the correct description, and this post starts to get at it, but adds another bastard word, unun. Two-windings that are coupled by a magnetic field are a TRANSFORMER. If the two windings have a terminal in common, they are an AUTO-TRANSFORMER. A coil of coax is a common mode choke (and not a good one). A section of transmission line wound around a ferrite core is a COMMON MODE CHOKE, and if well designed (choice of ferrite material, number of turns) can be a very good one. Transformers and auto-transformers transform impedance by virtue of their turns ratio. Arrays of common mode chokes can also be used to match circuits of different impedances. Last I looked, there was no description of the Elecraft "balun" telling us what it is. Perhaps Eric or Wayne could add that to the catalog listing for it. Another point. SWR is NOT an indicator of how well an antenna works. High SWR DOES increase loss in a feedline, but that matters only with long feedlines and small diameter coax. That does NOT matter for typical portable (or even mobile) operation, where feedlines are much too short for loss to matter. A high value of SWR as seen by a transmitter DOES limit that power that the transmitter can put into the antenna. That's where the antenna tuner comes in -- it transforms the impedance at the transmitter end of the feedline (or the end of a wire plugged into the coax connector combined with the counterpoise connected to the chassis) to the 50 ohm resistive impedance that the transmitter wants to drive. If we make RF current flow in a wire, it will radiate. How well it radiates depends, of course, on its orientation. A wire laying on the ground doesn't radiate very well. :) A wire without a counterpoise will use whatever it sees as a signal return. If that return happens to be the earth, the earth, which is essentially a big resistor, will burn much of the transmitter power. The "good" lengths of wire Wayne and those spreadsheets list are simply lengths that are likely to present an impedance within range of most antenna tuners for the bands that the operator is likely to use. 73, Jim K9YC On Tue,1/31/2017 7:31 AM, Morgan Bailey wrote: > Be careful in the 9 to 1 vs 4 to 1 vs 1 to 1.

Fortunately, it is much more straightforward that it might seem. A bal-un is a transformer. Technically, it has two windings on a ferromagnetic core material which for RF is typically some flavor of ferrite, usually in the form of a toroid. Practically, the transformer is often configured as an auto-transformer but it's still a transformer. In the classic case, a balanced load [e.g. center of a half-wave wire] becomes unbalanced [coax, shield grounded] by the bal-un. An un-un is exactly the same thing except both primary and secondary are unbalanced [i.e. one side is grounded ... and often connected together]. Transformers [bal-un or un-un] transform one complex impedance into another. The transformation ratio is equal to the square of the turns ratio between primary and secondary. The little transformer that used to go between the 300 ohm TV twin lead and the coax to the TV set had a 2:1 turns ratio, transforming 300 ohms to 75 ohms. A 4:1 turns ratio gives a 16:1 impedance transformation, 50 ohms becomes 750 ohms -- a 9:1 turns ratio gives an 81:1 impedance ratio and 50 ohms looks like 4 Kohms, roughly the practical impedance at the end of a half-wave wire. So Eric, the terms "advantages" and "disadvantages" are somewhat misleading. The goal is to provide your transmitter with a load of 50+j0 ohms. To work, the turns ratio of the bal-un must accomplish that and that in turn depends on your frequency and length of your wire. The "advantage" of the Elecraft balun is that it is switchable so one device can be used in multiple situations. Note that the impedance at the feedpoint is complex. It has both resistive and reactive [inductive/capacitive] components. Only at a resonant frequency will the reactance be zero. The bal-un/un-un transforms both components by the square of the turns ratio. It doesn't eliminate the reactance. So-called "current baluns" are really chokes that present a very high impedance to the current that might be flowing on the outside surface of the coax shield [common mode current]. They do not affect the equal and opposite currents flowing on the center conductor and inside surface of the shield. A dipole is anything that has two "poles." A length of wire has two ends [poles]. It doesn't matter how long it is. As Ron has pointed out before, the classic ham usage of "dipole" is a half-wavelength wire fed in the center, but technically, length is irrelevant. A water molecule is an electrical dipole built like a dumbell, one end is positive, the other negative. The field in the microwave makes them spin and their friction heats up your coffee. Hope this helps. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/30/2017 10:59 PM, gliderboy1955 via Elecraft wrote: > What are the advantages/disadvantages of using a 9:1 balun v. using the switchable Elecraft balun at 1:1 or 4:1 or no balun at all when using a random wire portable? > Why 9:1? > Thanks > 73 Eric WD6DBM > From k2vco.vic at gmail.com Tue Jan 31 14:22:50 2017 From: k2vco.vic at gmail.com (Vic Rosenthal) Date: Tue, 31 Jan 2017 21:22:50 +0200 Subject: [Elecraft] The "Kinda Random Antenna" In-Reply-To: <001e01d27be2$988034d0$c9809e70$@biz> References: <5620c49a-82c3-f1c7-cfe2-d3546a4f03cb@roadrunner.com> <1B22FB79-D09C-44FD-88FB-196138912569@liberty.edu> <3854BB1A-2FDD-4DBA-ABF2-BAFE3723EA24@elecraft.com> <11687a1e-d35e-06e9-edfb-c12cb015c7c5@foothill.net> <090e0d7a-d54d-9165-1e88-46a1f7e11a4d@triconet.org> <001e01d27be2$988034d0$c9809e70$@biz> Message-ID: I disagree. A center fed quarter wave will have a complex impedance of a few ohms of resistance and a very large capacitive reactance. SWR can be 100:1. I know, I am doing it. Why it works with good open wire line is that the line can transform the impedance to something that is easy to match with a practical tuner. For example, in my case I feed a half-size doublet with about a quarter wave of real open wire line, and it looks like a large INDUCTIVE reactance and high resistance at the shack end! It's easy to knock out the inductive reactance efficiently with a pair of capacitors, and a 4:1 balun transforms the high resistance to a value that gives about a 5:1 SWR on the short coax to the tuner. There is still (in my case) about 2.5 dB loss in the feed line due to SWR even at 40m, but I just run a kW instead of 500 watts and come out ahead.

The manual for the Elecraft BL2 shows exactly what it is: http://www.elecraft.com/manual/BL2_Balun_Rev_B.pdf Takes exactly 30 seconds to look at the schematic to see that the BL2 is a Rutheroff balun - two common mode chokes with the input in parallel and the output switchable between parallel (1:1) and series (4:1).

The 9:1 is generally an UNUN. When you run 100 watts or less most 1kw manufactured baluns or Ununs will take a wide variety of SWR if you are only running 100 watts. Because this thread is I believe about QRP the amount of power dissipated due to loss is not a factor. When you jump to 500 watts, core heating, saturation and breakdown are a risk. For instance, the W2AU balun that is manufactured as a center feed point for a dipole is only rated for the power at 1:1 SWR. In the printed literature the power rating drops off considerable as one goes to 2:1. I have personal experience with this particular balun when an 80/40 trap dipole was constructed using that balun and the Unadalla KW40 traps. Operating 40 was no problem as it was nearly 1:1 anywhere we operated [CW], but on 80 CW the bandwidth was much narrower, as to be expected and nearing the edges when we ran 500 watts into the antenna with the balun rated at 1kw, well, it's core heated up, SWR drastically changed, heating the core windings so much that the solder to the SO239 connecting the core to the coax melted off. We knew that the SWR was between 2.5-3:1 on the edges of the 80 meter range. So be careful. Additionally, I have little faith in stick Baluns or Ununs, I personally do not believe they are nearly as good as a Toroid constructed balun. Ununs seem to in my experience, tolerate wide ranges in SWR. I have used a 9:1 unun and their new 52:1 transformer for end fed antennas manufactured by Balundesigns.com with excellent results running 800 watts CW with little or no heating of the core and consistent results in a multiband environment. This was done using a 43, 53 and 87 foot end fed vertical/random wire/ inverted L and Half Square configurations. I have not modeled the pattern with NEC but I have compared it on Reverse Beacon Network [RBN] and I am definitely getting out. Full well knowing that Non resonant antennas are not as good as resonant ones, yes there is a difference in RBN reporting which favors the resonant, but, not always. This is because there is "funky lobe radiation" that can give a high report to just random one or two reporting stations and then the rest are 10-15 db less than the resonant over a wider area of report stations. This supports the pattern is not predictable, or as predictable as a resonant antenna installed correctly. Knowing we are addressing compromise installation for multiband usage, this I believe is acceptable. If you have goals of working or covering with gain and directivity, then there is no replacement for well designed and well installed resonant antennas. This is especially true in the competitive environment of contesting. When an antenna that is not balanced is used, the RF will seek a way to ground. Problems with feed line radiation, and RF in the shack are problematic. Using a counterpoise or limited radial system is recommended to provide the missing balance and a path to ground. This is generally not a problem at QRP levels but because a few 100 miliwatts of power coming back to the shack does not cause much problems but, jump that up to 10 or 100 watts and problems will surely make your life a living hell trying to keep the computer, keyboard, mouse cables connected and ATU from resetting and starting tuning cycle again and again. Best solution is to run resonant balanced antennas if one can, if one can't, invest in a few line isolators for the coax before it hits the shack and then have a good stock of Mix 31 ferrite beads for each cable in the shack, eg, usb, keyer, mic, speaker, keyboard, mouse...you get the idea. In the end, when one runs QRP power, balun/unun saturation and performance degradation, allows most anything to fly, jump the power to 100 watts, watch out, then to 800 watts...reforming injection formed plastic is in your future. Although, relative to this discussion, making an unun or balun with a T25 core and 32gauge wire will most likely produce the same disasterous results with 10 watts. LOL. Finally, Any antenna is better than No antenna.

Small autotransformer baluns like the LDG 4:1 I use (I haven't tried the Elecraft one but I assume it's similar), are just really practical because they have screw terminals for the LW and the counterpoise. It's pretty easy to build your own if you really want to, but what happens inside that box is not likely to have a huge effect on the QSO's you manage. For portable ops, rearranging the long wire/counterpoise a bit is likely to improve your signal more than switching from a 4:1 balun to a 9:1, or none at all. 73, Thomas OZ5TN (aka M0TRN, AF7BE) On 1 February 2017 at 01:02, kevinr at coho.net wrote: > We have all learned to say, "Yes Dear." and carry on. > > 73, > > Kevin.

If I did the math right (always a question) your load must be between about 5 ohms and 500 ohms, so if your antenna is about 400 ohms (not resistance, but impedance) then you're okay. If you have a 600 ohm antenna, the tuner won't be able to give the finals in the transmitter a perfect 50 ohms. Use a 4:1 Balun, and your 600 ohm load would be transformed (a balun is a transformer) 150 ohms and the tuner would handle it just fine. Use a 9:1 Balun and your 600 ohm load would be transformed to about 66 ohms. That doesn't say the antenna would radiate it, but the transmitter could make power and the tuner/transmission line would deliver it to the radiator. 73 -- Lynn On 1/30/2017 10:59 PM, gliderboy1955 via Elecraft wrote: > What are the advantages/disadvantages of using a 9:1 balun v. using the switchable Elecraft balun at 1:1 or 4:1 or no balun at all when using a random wire portable? > Why 9:1? > Thanks > 73 Eric WD6DBM From k9ma at sdellington.us Tue Jan 31 20:17:31 2017 From: k9ma at sdellington.us (K9MA) Date: Tue, 31 Jan 2017 19:17:31 -0600 Subject: [Elecraft] 9:1 Balun In-Reply-To: <76164b30-6059-15e4-66fb-bdc3ed018d39@ColdRocksHotBrooms.com> References: <76164b30-6059-15e4-66fb-bdc3ed018d39@ColdRocksHotBrooms.com> Message-ID: <3357e978-1b89-7233-7aed-2f59fb09e070@sdellington.us> On 1/31/2017 19:03, Lynn W.

Not necessarily. That 400 Ohms could be almost pure reactance, like 1+j399.999, an almost infinite SWR. That's why ATU specs call out the SWR range. Even then, that might be for mostly resistive loads, as it's really hard to specify the whole range of impedances an ATU can match. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From KX3 at ColdRocksHotBrooms.com Tue Jan 31 20:25:17 2017 From: KX3 at ColdRocksHotBrooms.com (Lynn W.

Seems to me if you can deliver power then what's not being radiated as heat would be radiated as RF. I have weird ideas about how all this works. One thing I think would be great to have, especially built in as part of an antenna tuner, is a switchable BALUN. When someone needs to throw up random antennas it would be handy to be able to just switch in the appropriate ratio. Can a BALUN be tapped maybe? It seems it would extend the range of internally antenna tuners also. I should know this stuff. But I don't. 73, Kev K4VD From thomas at horsten.com Tue Jan 31 20:53:21 2017 From: thomas at horsten.com (Thomas Horsten) Date: Wed, 1 Feb 2017 02:53:21 +0100 Subject: [Elecraft] 9:1 Balun In-Reply-To: References: <76164b30-6059-15e4-66fb-bdc3ed018d39@ColdRocksHotBrooms.com> Message-ID: Many manual ATU's consist of a variable capacitor and a tapped inductor. It's a matching network but also works as an "on-the-fly" switchable balun. The difference is the location. The ATU typically sits at the rig end where a balun sits at the antenna feedpoint (and so may present the coax with a better matching impedance, plus acts as a choke reducing common mode current). You can have a remote-controlled automatic ATU at the feed point in which case you'll always have a perfect match for your coax. Great for a stealth multiband in the attic, but it's an expensive and clunky solution for portable operations. 73 Thomas OZ5TN (aka M0TRN, AF7BE) On 1 February 2017 at 02:35, Kevin - K4VD wrote: > One thing I think would be great to have, especially built in as part of an > antenna tuner, is a switchable BALUN.

A lot depends on frequency - at higher frequencies the "SWR matching range" will be greater than on lower frequencies. The only valid spec for the matching range is the available inductance and capacitance in the ATu, as well as the step size. The Elecraft tuners do state that in their specifications. The range for the Elecraft tuners is often quoted as a 10:1 SWR, but that depends on a lot of factors, such as the frequency and the exact impedance to be matched. You may take the inductance/capacitance values in the Elecraft tuner specs as well as the step size and run that data through an application like TLA for windows (On the ARRL Antenna book CD or download from the ARRL website) to find the actual SWR range that can be matched on any tuner. The resulting data is more informative than simply stating that the ATU can match any particular SWR, 73, Don W3FPR On 1/31/2017 8:17 PM, K9MA wrote: > That's why ATU specs call out the > SWR range.

The modern consensus is that only common mode chokes should be used on the feedline. They should have enough inductance at the frequency of interest to keep the RF off the outside of the coax. See the works published by Jim Brown K9YC for a thorough discussion of RFI and "baluns" (common mode RF Chokes) for use in the amateur community - http://audiosystemsgroup.com/RFI-Ham.pdf. 73, Don W3FPR On 1/31/2017 8:35 PM, Kevin - K4VD wrote: Can a BALUN be tapped maybe?

The ultimate selectivity is provided by the DSP bandwidth, and not the roofing filter. The reason for the more narrow roofing filter is to provide isolation from nearby strong signals that are within the roofing filter passband, but outside the DSP bandwidth. If strong signals come into the K3 outside theDSP bandwidth, but inside the roofing filter bandwidth, they can cause AGC "pumping" and reduce the overall sensitivity of the K3 receiver as a result. If you are operating in contest situations, or trying to respond to DX stations who are 'working a pileup', that extra bit of roofing filter may be needed, but for more casual operation, save your money. 73, Don W3FPR On 1/31/2017 9:07 PM, abullington at comcast.net wrote: > I just got my new (used) K3/10 in the mail yesterday and have been having a blast with it.

It's probably done for the same reason your TV and almost all other electronics in your household (including things like TVs, modern dishwashers, washing machines, etc.) in addition to your computer(s) are not truly "off" unless you unplug them. It's the current "fashion" in engineering. Note that your K3/K3S works the same way but has no rear panel switch. The so-called 'parasitic power drain' of all those appliances in their "off" state adds up costs for the individual and for the community and the nation. In addition, the soft glow from LED's on the various appliances (thankfully not the Elecraft gear) can be deleterious to your health if they are allowed where you sleep. Studies have shown that even though you are not aware of it, their presence can interfere with normal sleep rhythms. A starry bright sky can be a pleasure at times but, frankly, us Humans evolved getting our best rest sleeping in a very dark cave.

The classic example of "radiating power" that is completely and totally uninteresting is when you dump the power into a resistor (a dummy load) and the power is radiated as heat. There is a contest where the participants take whatever metal stuff they find lying around, load it up and operate. It's proof that lots of things can work, more or less. The light-bulb example is another one. I know that a 50 ohm source, going through a 50 ohm feedline into a 50 ohm load means minimal loss in the feedline. If you have 1/4 wave of coax with 100 ohm load the feedline will act as a transformer and you'll have 25 ohms at the transmitter -- and that means power lost as heat. It also means the length of the feedline, in wavelengths (and therefore frequency) matters in the overall antenna system design. That's why the balun should not be at the radio end, it should be near the antenna. If it's a permanent installation, taking the time to figure it out and get everything matched up is a good thing. Ladder line is well loved because it isn't as lossy as coax when things aren't matched. Tossing the radio (gently!) onto a picnic table at a park and throwing a wire into the air is different. Maybe it works, maybe it doesn't, but you don't have a lot invested in the antenna system, and you can pick wire lengths that'll be "good enough" -- and "good enough" often is good enough. This discussion started with what were good and bad lengths for an ad-hoc, non-resonant wire. Having some sort of 4:1, 9:1 or 16:1 balun (or un-un) gets important if your wire happens to be near resonance. 73 -- Lynn On 1/31/2017 5:35 PM, Kevin - K4VD wrote: > > On Tue, Jan 31, 2017 at 8:03 PM, Lynn W.
