It's in the firmware release notes. MCU 4.31 / DSP 2.72, 3-23-2011 other text removed Remote-Control/Switch Macro Command Changes: * AP COMMAND TURNS APF ON/OFF: You can turn the CW audio peaking filter on/off by sending AP1; or AP0;, respectively. Applies only in CW mode with CONFIG:DUAL PB set to APF. (Not yet available for direct sub receiver control. Swap VFOs or do AB copy in order to set up sub receiver APF.) You can use this command to create a TAP function to turn APF on/off; use the Help function in K3 Utility for details on macros.

[Elecraft] Second Configuration
Hi, I'm wondering if there is any chance that the KX3 might be offered in the more traditional desktop configuration i.e. user interface on a front panel, connectors on the back? This would be for those of us not interested in a trail-friendly package but rather a small high performance home station QRP rig? 72/73, Jim, K4AXF Grottoes, VA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] New K line station
Hello all, I put the new K3, P3 and KPA500 on the air yesterday for the first time. I built them on a 20 hour building jag Mon/Tues. Other than me not reading the instructions carefully at times and fingers that don't fit/work as well as they used to (those #2 washers are tiny), it all went together very well. The front panel of the K3 was a bit of a bother, but it worked and now I have to take it apart for the second receiver when it arrives. :-\ I just listened for a couple days, trying to learn menus and control locations. It's not immediately clear how to set TX output levels according to the status of the KPA500, but I figured it out. What an amazing system, It all works beautifully. No, it's not a surprise, but is very satisfying. Well done Elecraft.

Re: [Elecraft] Second Configuration
Jim, For my part, like the KX1, it is quite comfortable to operate as-is in a home station environment. Built in legs in the rear can be extended and make it quite easy to use the tuning knob and the buttons if you prefer that over the flat on the desktop position. In a few months, you may be able to try one out at a hamfest where there is an Elecraft booth before deciding that it would be better with a vertical front panel. As has been pointed out, the K3 does offer the traditional front panel with connections in the rear. 73, Don W3FPR On 10/20/2011 10:06 AM, Jim Stoneback wrote: Hi, I'm wondering if there is any chance that the KX3 might be offered in the more traditional desktop configuration i.e. user interface on a front panel, connectors on the back?

Re: [Elecraft] Second Configuration
Hi Jim, I think you'll find that the KX3 works just as well at home as in the field. The tilt feet in the back hold the radio at a very convenient operating angle, and all the cables we supply have right-angle plugs to keep things looking sharp. I'd encourage anyone with a KX3 to keep a charged internal or external battery pack around, as well as a portable antenna system. You just might have a hankering to operating the field, or encounter an emergency situation. (You can create your own emergency situation, if necessary, by attempting to operate in the field with your old 50- pound radio :) 73, Wayne N6KR On Oct 20, 2011, at 7:06 AM, Jim Stoneback wrote: Hi, I'm wondering if there is any chance that the KX3 might be offered in the more traditional desktop configuration i.e. user interface on a front panel, connectors on the back?

[Elecraft] K3: PSK mixed mode
I've been playing around with PSK a bit with my PC and the K3. One thing I don't care for with the digimodes is the need to drive the transceiver with audio out from the PC. Messing with the drive levels and being wary of PC audio sounds is a turn off. The K3 has PSK-D which provides a nice facility for sending without those issues. It would be nice to have a program which combines PSK-D sending with the waterfall ability of a PC receiving/decoding the audio. That would give a (limited) panoramic view, point and click QSY and AFC. It seems like this is possible but haven't seen it done. The K3 provides the audio regardless of whether PSK-D or PSK is chosen. All these programs already send and receive data to/from the K3 via the serial link. It would seem like a small addition to add a KY stream for sending in place of the audio output modulation. I realize it would require QSY to the received signal but that doesn't seem like a big deal. Are there other reasons which prevent this?

Re: [Elecraft] K3: PSK mixed mode
Jim, If you can convince the authors of the software that provides the waterfall display you wish to send an ascii stream to the K3 via the KY command(s), then what you wish will be accomplished. The K3 has made that provision possible, but so far, only a couple applications have chosen to take advantage of it. I am not certain about the inclusion of point and click, you may have to tune the signal to a certain point on the waterfall display - it all depends on the software author. For an parallel approach for RTTY using PSK-D, take a look at what is available with MMTTY. Something similar could be done with PSK-31. 73, Don W3FPR On 10/20/2011 11:34 AM, Jim Miller wrote: I've been playing around with PSK a bit with my PC and the K3.

[Elecraft] What Would it Take to Use P3 as O-Scope for Audio Modulation?
Since there's a lot of room left over in the P3 box, would it be possible/practical to (some day) be able to use the P3 to optimally set-up audio signals and to monitor modulation signals going to the transmitter. (i.e. visually verify optimal set-up of one's rig prior to operating.) How could we extend the K3's built-in test capabilities with the P3? (I know that mods and added circuitry would be needed in the K3 too to address such capabilities. Perhaps it's possible to display a received signal for more critical analysis too??? As long we're dreaming -- what else would be want in the P3 for it to be the optimal K3 stationmate along this line of thought? Thanks. 72/73 DX, Craig W.

[Elecraft] K3: Use of KDVR3 on sub transmit
Am I right in thinking that I need to completely flatten the tx equalisation before recording on ssb with the KDVR3? I am using the MD2 microphone and when I listen to the recording it is accompanied by a lot of digital artefacts which I assume are being transmitted. Listening to the microphone directly with the monitor function it sounds great. I have had the voice recorder for 12 months now and have used it mainly loop recording on rx. This is the first time I have tried voice recording, thinking it to be a more civilised means of calling in a pileup and sparing my wife the pain of hearing me repeat two letters over and over again, which is why I almost exclusively use CW! I'm using all the latest firmware. 73 -- Stephen __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: PSK mixed mode
It's just something software authors have not bothered with since they already work with audio with no problems. There are two programs which may be of interest KTune has a function for a digital window using FSK-D and PSK-D using the K3 com port. I don't recall if there is a waterfall or not. TRX-Manager is a pay program. The K3 monitoring window has a feature where you can send CW, PSK-D and FSK-D over the RS232 port. But there is no waterfall. HRD works with the KY command for CW but not for PSK-D. 73 Greg AB7R On Thu, Oct 20, 2011 at 8:34 AM, Jim Miller j...@jtmiller.com wrote: I've been playing around with PSK a bit with my PC and the K3.

Re: [Elecraft] K3: PSK mixed mode
I thought about it a bit more and there would not be a need to retune the K3 receive side if split was used. VFO A would be used to set the listening range that the PC operated its decoding on (~2.5Khz) and that same program could QSY VFO B for transmitting (KY stream) in split mode so that the display wouldn't need to be slewed each time a new QSO was started. PSK is narrow band enough that a few Khz visible can contain many signals. I don't have a dedicated ham shack PC. My one laptop serves multiple purposes and not fiddling with the audio to ensure it is properly setup for PSK would be nice.

[Elecraft] Second Configuration
I am seriously considering the KX3 to replace my FT-817 (early version). It will probably live in the shack most of the time and only mobile if making a long trip. I seem to recall seeing a bracket attached to the back that looks like the radio would slip onto a single metal bracket. If so then buying two mounting brackets (one for in the vehicle and other attached to the shelf in the shack would provide the easy solution). The bracket I saw in the photos looked like it would make for fast install/removal. Regarding connectors I did not see anything that would be a problem for use in the shack. I run two antenna cable to my FT-817 (432 antenna goes to the front BNC using a right angle male connector). 144 antenna goes to the back SO-239. The KX3 has a single BNC, I believe. If 2m module is added it may have a separate output connector (or not)? I recently talked with Wayne and they are currently working on the 2m unit. He did not say if it would get offered at the same time the KX3 is rolled out. Expectations for the KX3 is Christmas (?) so ordering might start a bit before that (but I have no inside info regarding that). I will begin selling off some equipment to raise the necessary cash (IC-V8000, D3010, FT-817, ...the neighbors noisy dogs...the moose that trashed my eme antenna...). 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] Second Configuration
Wayne, Fair enough. Seeing that the FT-817 is decade old technology, goes without saying it is not really in the same league with the KX3. I originally bought the FT-817 to be the 1st IF (144-MHz) for my mw transverters and was a good choice for the time (2000), but it never lived up for battery operation with its high Rx current draw. I suspect (expect) the Rx performance to be uncomparable for the KX3 and one (good) reason for considering the upgrade. Microwave operation is a test of weak-signal performance and Elecraft has long demonstrated doing this well. Most DX shots on mw bands still is via CW (though digital is making headway). Before the announcement of the KX3, I had considered taking my K3/10 into the field for mw shots. But I would be concerned about size and exposure of the investment I have in it. The KX3 will be appropriate and its footprint looks like a good fit for that of the FT-817 (for mounting on my portable mw rig). The embedded 2m transverter is key to that. But I expect the KX3 to put in a respectable performance on HF which I never really used on the FT-817. Of course adding a 100w PA for HF mobile and a small PA for 2m mobile. For trips on the airlines it should pack very nice as a standalone QRP rig. So we are all waiting for the announcement of when the KX3 will become available (I signed up for that). Thanks, Ed - KL7UW PS: The K3/10 has replaced my FT-847 (which I sold) as the main radio in the shack. At 09:55 AM 10/20/2011, Wayne Burdick wrote: Edward R.

Hi Doug, Size ignoring knobs and connectors (i.e., just the chassis): KX3: 3.45 x 7.45 x 1.7 = 43.7 in^3 FT-817: 7.1 x 5.3 x 1.5 = 56.4 in^3 The FT-817 is 29% larger by volume using this metric. If we include knobs and connectors, the KX3 is a bit larger: KX3:3.45 x 7.85 x 2.45 = 66 in^3 FT-817: 7.7 x 5.3 x 1.5 = 61 in^3 I guess it depends on what you're packing the radio in. If you're talking about a hard-shell case, you'd need one a little smaller for the FT-817. If you're stuffing it into a soft pack or rolling it up in your backpack with clothes, the KX3 wins :) Weight (less batteries or options): KX3: 1.49 lbs FT817: 2.06 lbs The FT817 is 38% heavier. This, of course, is what matters most if you're hiking. Note that the KX3's attached paddle (KXPD3) weighs about 1 oz. I usually carry 1 oz. of #26 antenna wire and a 1-oz. fishing weight to get the wire into a tree. Add another 8 oz for batteries and 5 for the mic, and you're at about 2.5 lbs for the entire station. 73, Wayne N6KR On Oct 20, 2011, at 2:20 PM, DOUGLAS ZWIEBEL wrote: Surprised to see Wayne say that the KX3 is smaller than the FT817 (I own the latter).

Re: [Elecraft] KX3 dimensions?
Getting more excited by this radio by the minute. Seems to me, even with the relatively heavy G4TPH portable loop and whatever stand I manage to cobble together for that (thinking lots of PVC in one foot or 15 inch sections, tall enough to get the loop off the ground by a foot or a foot and a half, this is going to be one very lightweight station and lots of fun (and easy) to carry around. Sorry, afraid I'll have to go a little heavier on the antennas than Wayne does, my aim isn't very good. Even so, taking a complete station in well under five pounds, if not for hiking, certainly for hotel stays and other vacationing, is really, really attractive. By relatively heavy, I mean as compared to Wayne's one ounce of 26 gauge wire. I expect the loop, consisting of 10 flat pieces of aluminum bolted together with a tuning capacitor, can't weigh more than the KX3. But that is quite a bit heavier than one ounce :) -- Buddy Brannan, KB5ELV - Erie, PA Phone: (814) 860-3194 or 888-75-BUDDY On Oct 20, 2011, at 7:31 PM, Fred Jensen wrote: On 10/20/2011 2:49 PM, Wayne Burdick wrote: Note that the KX3's attached paddle (KXPD3) weighs about 1 oz.

Re: [Elecraft] K3: PSK mixed mode
Jim, If you are serious about doing digital modes, I would highly recommend a dedicated PC for the hamshack, and I would further recommend a desktop running Windows XP. Most all ham applications will run on XP, but some have trouble on Vista or Win7. A desktop allows you to install real serial ports (which work better than USB adapters, and support multiple soundcards. I would suggest a re-furbished off-lease PC - they are often available with WinXP Pro and are priced in the $200 range (monitor not included). I particularly like the IBM desktops, but there are many others that will serve quite well - one source is www.tigerdirect.com. For most ham applications a 1.5 GHz processor with 512MB (or 1 GB) of RAM and a 40 GB Hard drive is plenty of 'horsepower' - yes, there are some combinations of applications, like HRD with LP Bridge and PowerSDR that will bog that size computer down, but most ham applications will run with ease. 73, Don W3FPR On 10/20/2011 1:29 PM, Jim Miller wrote: I don't have a dedicated ham shack PC.

Well, I finally pulled the trigger and ordered KPA500 and connecting cable tonight. I've been dragging my feet on this purchase for several months now. The deciding factor was a new DXCC for me on 10 meters. I haven't made the 10 meter mod to my current amp (AL-811H). This will make things much easier in the future; instant on, instant use... no longer waiting for the tubes to warm up! I already plan on buying the auto-tuner when it becomes available to complete the K-line. I have the P3 and am waiting for the soon to come mod allowing the hook up to a big monitor.

Re: [Elecraft] Now General RF Issue WAS 160m loop experiment a big failure
Dear Group, I apparently have a bigger problem with RF in the shack and it has nothing to do with the loop. I have been running a successful shack on the second floor of my house and as of Friday last week when I installed the loop I have had nothing but RF problems. I thought on Saturday when I removed the ladder line from the shack and coiled it up in the tree far away from the shack that I would be ok and everything seemed to be ok. Anyway long story short, now with only the dipole (alpha delta trapped dipole at 30 ft) connected in the shack I have terrible RF problems and it can occur even barefoot at 100w so I am not pointing to the amp as of yet. I have dropped the antenna and checked that the coax is tight, checked to see if the coax is tight at the lighting arrestor, ran with and without the tuner connected. I have rechecked the grounding that I have in the shack, which after more research is not adequate, and I will be addressing that this weekend. However, I don't think that this will fix it. Right now I am thinking that I have a bad coax line outside of the house. The reason for this is that I had a new propane tank installed and they needed to back the truck up and had to drive over the buried coax. I did put boards down to spread out the load and protect the lawn and also the coax. However the problem has started since this incident. I pulled the coax out of the ground and it has bend marks at the edges where the boards were which to means that it was deformed and maybe it is now crushed. So other than doing a whole new ground setup with more ground rods outside and adding more chokes to the coax, I want to check out the coax that I have this weekend to determine if I have a crushed problem. Is there a way I can check it out with my 259b or is it just replace it and see what happens. Anyway, I am off the air until I get this sorted out. Basically now I have to start over, and frankly speaking I am a bit overwhelmed right now so I just need a friendly group to lean on as I really am frustrated right now as my favorite pastime is now no longer possible due to some failure of some kind or another.

Re: [Elecraft] K3: PSK mixed mode
Joe, What you say is partially correct (it all depends on your definition of dead). WinXP is still supported for security updates from Microsoft. Although, MS will no longer answer specific questions relating to WinXP, they are still providing support in the form of security updates. While I can agree that official support for a particular OS may be important, to some hams who want to run legacy applications, that is not possible with Win7 because it prevents applications from storing into their application folder - instead, insist that that data be stored into each users Documents and Settings folder. Which is better - it all depends on what you want to do. If the author for the application that you wish to use is worth his salt, then the most recent download of that application will work on Win7 - and will likely run on WinXP (there may be exceptions). But if the application author has not been keeping up with updates in the MS OS migration )legacy applications), those applications may work under WinXP and fail under Win7. So each user must make a choice of the OS to be used. Make that choice based on your need for legacy applications - if you have no need for those, then Win7 is the clear winner. I stick with WinXP for reasons unrelated to this discussion. 73, Don W3FPR On 10/20/2011 8:48 PM, Joe Subich, W4TV wrote: If you are serious about doing digital modes, I would highly recommend a dedicated PC for the hamshack, and I would further recommend a desktop running Windows XP.

Re: [Elecraft] Now General RF Issue WAS 160m loop experiment a big failure
Don, You MFJ259B can help you locate the fault. Look at the instructions for the 259B and in particular the Distance to Fault section. Yes, crushed coax can cause severe discontinuities, including actual shorts in the coax - not unlikely for coax being run over by heavy equipment. A shack on the second floor is always a problem for RF. A ground wire to a ground rod (hopefully also connected to the utility entrance ground rod) will provide a good path for AC Mains faults, and may also provide *some* lightning protection, it will not serve well for an RF ground point. The distance between the ground rod and the shack connection will have some reactance due to its length - if it is near a quarter wavelength, it will present a high impedance in the shack - to be effective, an RF Ground point should present a low impedance at the shack location. This may ba a case where the only good solution is he use of counterpoise wires. A quarter wavelength of wire on each frequency of interest will present a low RF impedance at the shack end and a high impedance at the far end of the wire. You may have to resort to this 1/4 wave wire as your best solution. Some experimentation may be required. 73, Don W3FPR On 10/20/2011 9:21 PM, gold...@charter.net wrote: Dear Group, I apparently have a bigger problem with RF in the shack and it has nothing to do with the loop.

Dave, That says we can obtain updates for WinXP until April 8, 2014. That gives me almost 2 1/2 years to consider where I go from this point forward for my choice of Operating Systems.

Maybe I can find some method of making my Linux computers have full file access to my Windows based network shared files, but so far, Samba has not done the deed properly for me - sometimes it works, sometimes not. I do hope that is resolved because for economy reasons, the upgrade for me from WinXP is Ubuntu - I just have too many computers running WinXP to purchase Win7 for all of them. 73, Don W3FPR On 10/20/2011 10:15 PM, Dave Perry wrote: My last email lost its format.

Re: [Elecraft] K3: PSK mixed mode
Don, I was specifically speaking to *new* installations ... try to find a fresh copy of Windows XP - particularly Windows XP Professional which is the only version worth having - for sale at any reputable dealer. You certainly will not find it at New Egg or Tiger Direct. Second, I don't know where people are coming up with an end of support date in 2014 for Windows XP. This Microsoft site http://windows.microsoft.com/en-us/windows/help/end-support says: Support for Windows XP with Service Pack 2 (SP2) ended on July 13, 2010.* Considering that new Windows 7 systems with 2 GHz dual or quad core processors and 4 GB of RAM are regularly available for less than $500, I don't understand why anyone would spend more than half that for a 500 MB/1 GHz single core system with Windows XP ... it simply is not long term thinking. The recycled XP box will have no support and gather dust while the higher performance system is still a mainstream performer. 73, ...

Re: [Elecraft] Now General RF Issue WAS 160m loop experiment a big failure
I wholeheartedly endorse Don's comments. A good practice with any antenna installation is to check the SWR on each band for which it is used, and make a note of that. That can help determine whether an antenna problem is responsible for any sudden changes in behavior by simply rechecking the SWR. Alternatively (and more accurate) you can use your antenna analyzer and note the impedance at the feed point. If you live in an area with lots of moisture and snow, a check in mid-summer and another in mid-winter is useful. Significant differences can occur with a normally functioning antenna from winter to summer. The 1/4 wave wires Don mentions can be in the shack. In similar situations I've run them along the baseboard in the shack, sometimes out under the door and down a hallway. Just be aware that the far end of that wire may have significant RF voltage present while transmitting. If you run several, you can run them in parallel for much of their length, then separate each one for the last several feet so its end is away from the longer 'radials'. Good luck. Isn't messing about with antennas fun? (And this is supposed to be done in mid-winter, don'cha' know? You get more RF mojo from fixing up the antenna in a snowstorm than on a nice summer day.) 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Thursday, October 20, 2011 7:28 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Now General RF Issue WAS 160m loop experiment a big failure Don, You MFJ259B can help you locate the fault. Look at the instructions for the 259B and in particular the Distance to Fault section. Yes, crushed coax can cause severe discontinuities, including actual shorts in the coax - not unlikely for coax being run over by heavy equipment. A shack on the second floor is always a problem for RF. A ground wire to a ground rod (hopefully also connected to the utility entrance ground rod) will provide a good path for AC Mains faults, and may also provide *some* lightning protection, it will not serve well for an RF ground point. The distance between the ground rod and the shack connection will have some reactance due to its length - if it is near a quarter wavelength, it will present a high impedance in the shack - to be effective, an RF Ground point should present a low impedance at the shack location. This may ba a case where the only good solution is he use of counterpoise wires. A quarter wavelength of wire on each frequency of interest will present a low RF impedance at the shack end and a high impedance at the far end of the wire. You may have to resort to this 1/4 wave wire as your best solution. Some experimentation may be required. 73, Don W3FPR On 10/20/2011 9:21 PM, gold...@charter.net wrote: Dear Group, I apparently have a bigger problem with RF in the shack and it has nothing to do with the loop. I have been running a successful shack on the second floor of my house and as of Friday last week when I installed the loop I have had nothing but RF problems. I thought on Saturday when I removed the ladder line from the shack and coiled it up in the tree far away from the shack that I would be ok and everything seemed to be ok. Anyway long story short, now with only the dipole (alpha delta trapped dipole at 30 ft) connected in the shack I have terrible RF problems and it can occur even barefoot at 100w so I am not pointing to the amp as of yet. I have dropped the antenna and checked that the coax is tight, checked to see if the coax is tight at the lighting arrestor, ran with and without the tuner connected. I have rechecked the grounding that I have in the shack, which after more research is not adequate, and I will be addressing that this weekend. However, I don't think that this will fix it. Right now I am thinking that I have a bad coax line outside of the house. The reason for this is that I had a new propane tank installed and they needed to back the truck up and had to drive over the buried coax. I did put boards down to spread out the load and protect the lawn and also the coax. However the problem has started since this incident. I pulled the coax out of the ground and it has bend marks at the edges where the boards were which to means that it was deformed and maybe it is now crushed. So other than doing a whole new ground setup with more ground rods outside and adding more chokes to the coax, I want to check out the coax that I have this weekend to determine if I have a crushed problem. Is there a way I can check it out with my 259b or is it just replace it and see what happens. Anyway, I am off the air until I get this sorted out. Basically now I have to start over, and frankly speaking I am a bit overwhelmed right now so I just need a friendly group to lean on as I really am frustrated right now as my favorite pastime is now
