Even better, by activating SPLT SV as you mentioned, one can band hop and go right back to the saved split settings without having to recall the memory. For example, I had called the CW Rx split procedure as I described for 40M -- then tuned around on 20M SSB for a while and came back to 40M where all settings were brought back with the just the band change button. Even tried powering down the rig, and all settings came back at power-up. Probably the only distraction with the procedure is that the lower, smaller frequency display becomes the real operating frequency for CW off-set purposes. Oh, and CW spot will not work this way either. So, opening up the DSP filters in a future f/w release for CW Rx mode is still the preferred way of accomplishing this. Still, the flexibility to accomplish this in the K3 and still retain all the QSK attributes is damn impressive.

[Elecraft] K2 SSB digital modes
(Brian WB6RQN asks for an easy way to do digital modes on a K2, for his Montessori school rig:) If you have a Mac, the soundcard SSB modes can be done easily. I use CocoaModem. Receive needs only a stereo cable from the K2, either the headphones jack or the aux speaker, to the mic input on the computer. On recent Macs, at least, the mic input is isolated and needs no transformer -- just straight stereo plug to stereo plug. Vox works very well for transmitting; it needs a cable with stereo plug on the computer end (into the headphones socket) and a voltage divider on the K2's mic plug (two resistors soldered into an 8-pin plug). Specifications are on the Elecraft web site, in Builder Resources, PSK31with the K2 by WA7SPY. Setting the vox level takes some fiddling, but just in the computer output volume, not in the K2. If you don't want to use vox, you need more hardware to get the PTT line out a USB port. CocoaModem is exceptionally good software, by Kok Chen, W7AY http:// homepage.mac.com/chen/index.html. His CocoaNec is great, too. Both are free. There are a couple of modes that CocoaModem doesn't do -- SSTV is available in MacRobot, but some modes just aren't available on a mac.

Re: [Elecraft] K3 CW Rx Audio
Ok, as it is now you can open up CW rx all the way to 2.8 kHz if you like with the 2.7 kHz filter installed - and *enabled* for CW mode. Do you have the 2.7 kHz filter enabled for CW mode? If not, then I can understand the need for this split setup to open up the DSP filters for CW rx. Since filters are enabled on a per-mode basis, things can get a bit confusing.

Hello, My fully loaded K2 is a great rig to use. I have spent a lot of time building, troubleshooting etc to get it up and running the way it should work, it is a keeper. I'm still working on a XV50, that has major problems, and awaiting an KAT100 autotuner (on Back order), but when everything is up and running will have a very nice station. I'm going to sell a Collins 75A-4, one of my R-390a's, Collins 32S-1 and 75S-1 to pay for an on order K3. I'm still love boatanchors, and will keep the gear I most like, but want a K3.

Re: [Elecraft] K2 not dead yet
Brian Fine on your progress with this fine rig. I plan to continue to enjoy my own K2 as the flagship rig of my station! On PSK31 and digital modes -- you don't need to modify your K2 -- check out the application note posted at elecraft.com. essentially all you need is a stereo cable on receive, a mic connector and a few parts on transmit, and some means to do the T/R switching. The kids will 'resonate' with PSK31 based upon their other PC experiences. Remember to run the K2 at approx half power when doing the digital modes !! I have seen PSK31 at field day, and it tends to be rather tough in the pile-ups -- so calling CQ may be preferred if you run QRP-battery/solar. Meanwhile PSK31 may be ideal for non-contest operating with your youth. This is NOT the ideal time for QRP-SSB ! You just might need that amp. Do check the calendar for kids-day events, as this may charm them more than an array of 599 my state-is reports. And consider scheds to other schools or kids. Here in Maryland, a contact station is KI3DS. 73, curt --- Brian Lloyd [EMAIL PROTECTED] wrote: OK, We just finished the K2 for our school. I was planing to teach the kids to solder and wanted a radio that the kids could build so I asked the ARRL for the K2 instead of the low-end Ikensu (Yaecomwood?) they were offering. I remember how much I learned from building Heathkits, Knight kits, and Eico kits as a kid so I thought we could do the same with the K2. Construction took much of the school year (October to April) including a few dry spells when I sat after school and slung solder just so we would keep making forward progress. (It was a big project for 10-13 year-old kids.) Regardless, the K2, KSB2, and KNB2 are finished and on- the-air. The KPA100 is now in the build area and my star builders (5th graders who think that soldering is just about as much fun as you can have) have just unpacked, taken inventory, and soldered the first parts. (I took inventory too and couldn't find the output transistors. I darned near tore my hair out until I found the drawer where they had been carefully, neatly, and incorrectly stored.) We have 5 more weeks of school so we are going to have to push to get the KPA100 done, especially with all the other end-of-year projects. (I suspect I will have to keep the momentum going. Poor me. :-) I think I have said that we will be on the air for Field Day using the K2 with solar power. I hope to have a couple who will be ready to do some slow-and-simple CW QSOs too. Gotta get those multipliers! I know everyone is dumping their K2s so they can get a K3 but, gee- whiz, the K2 is some good receiver. I *love* this radio! I have had a LOT of radios come and go in the shack (top-of-the-line Kenwood, two sets of Collins S-Line, several Icom, a Yaesu station, and a plethora of Heathkits) and I have to say that, so far, I think this is my favorite radio, even at just 10W. The only thing it is missing (stock) is a good way to do digital modes. (I have seen the mod for getting audio out before the audio amp but not sure how well it will fit after getting the KPA100 in there.) So, the K3 looks like a superb radio. I want one.

RE: [Elecraft] Power pole for K3?
Notice to hams I have introduced a new DC power plug and socket for ham use It requires three special tools to strip the wire, twist it, and then crimp it into the connector (each tool is discounted at abt $100 each). The result requires soldering with silver solder, utilizing the Norcroft wicking tool (sold in 220VAC only), and the mating of the two halves with the preferred method of hay bailing wire (obtained from your neighbor farmer). Please note that it is possible to mate the two halves conviently so that reverse polarity is possible, as needed. These new connectors have the adoption of the National Amateur Radio Group and many manufacturers. It is recommended all hams immediately equip themselves with the proper tools for this great new fixture (not available outside of Utah). 73, Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; elecraft@mailman.qth.net Subject: Re: [Elecraft] Power pole for K3? Date: Sun, 20 Apr 2008 13:31:00 -0500 CC: OK, I'm late in throwing in my two cents. I have the Anderson Power Pole crimper and have used another also that is the correct size and has the proper jaws but it is not a ratcheting type. It is usable but is not as foolproof as the ratcheting type. The Anderson is the correct one and applies the proper force, and fits the sleeve and the wire size you are using. If you do not use this type, the wire will be loose or the connector deformed and will not fit or make a secure connection. What I am trying to say is that even IF you buy the Anderson crimper, you are likely to screw up a few of the first ones you try to crimp. Now you have to solder anyway or order some more connectors, not what you want when you are hot to get on the air. My suggestion, unless you have the proper tool and therefore are likely proficient at crimping, is to ORDER the wired set from Elecraft and save yourself the possible problems with first time crimps (OR SOLDER them in the first place). I will be making my own as I already have plenty stock of the all the parts and the proper tool and have made more than 100 connections so I do not feel intimidated by the process and the crimps that I get are very good electrically and physically.

[Elecraft] K2 - power out
A question about power out with my K2. I really had never paid attention to it before, so there may not be a problem. On the low bands, 40, 80 and 160M I get a little more than 100W out when set for 100W. On the other bands except 17M I get 98-100W out when set to 100W. On 17M I get 80W out when set for 100W. The voltage measures 13.0V key up and 11.8V key down on the K2's display on all bands when set for 100W. I made sure C32 and C34 were peaked - no difference. Any ideas or is this normal? Is my voltage dropping too much? Tnx, N2TK, Tony ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 CW Rx Audio
Bob, This has been re-hashed before by myself and others but here goes... The K3's CW receive bandwidth is presently limited to no greater than 2.8 kHz, even when the optional 6 kHz filter is installed. At the moment, the DSP is the limiting factor. I would rather not re-visit the rationale for wanting a wider CW receive bandwidth as that is covered in detail within the list archives. The procedure that I described is a means of opening up the receiver beyond 2.8 kHz while being engaged in a CW QSO. Simply put, it allows the use of SSB mode with an offset for CW reception (VFO A), while using CW mode ( on VFO B) for transmission. 73, Paul, W9AC - Original Message - From: Bob Cunnings [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Monday, April 21, 2008 10:27 AM Subject: Re: [Elecraft] K3 CW Rx Audio Ok, as it is now you can open up CW rx all the way to 2.8 kHz if you like with the 2.7 kHz filter installed - and *enabled* for CW mode.

Re: [Elecraft] K3 CW Rx Audio
Hi All, I'm a little confused about who is saying what here. If I read it right, Bill, W4ZV, is responding to Doug by quoting Fred! Have I got it right? In any event, I found this post to be very interesting. I read it twice, in fact, because as I went through it the first time I started getting a strong feeling that this was something not to be taken lightly. It seems to be very much like a pearl that comes from lots and lots of experience. In any event, I am fortunate to have both the K3 and an Orion II, and I intend to try and duplicate Fred's described setup to see if I can achieve the effect he outlines, and to do it with both radios. For one thing, I never use a tone as low as 400 hz. I've always set my radios so that the received tone was in the 600 to 700 hz range. Apparently, according to Fred, I may be doing it all wrong! My reaction has always been that a lower tone seemed to sound too much like the background noise, so I set things higher. Also, I'm not sure I've ever reached for the notch control to limit nearby QRM, unless it was hetrodyne type of interference. Shame on me I think. This may be partly because I'm still somewhat married in my operating habits to the old notch technology which meant that using a notch on CW was counterproductive. If the interference was anything other than a solid tone (i.e. hetrodyne), using the notch would cause the CW signal to be also notched. Poof! But newer technology, like that on the K3, allows you to notch out a variety of offenders without materially degrading the received CW signal. Now, I know that, but for some reason I haven't taken full advantage of it. This probably exposes the fact that I may not have read the manual sufficiently! Now that I think about it, I can say that I have recently tinkered with the notch when trying to deal with the chinese radar on 40 meters, and with some success. You might think this would have caused my hand to slap my forehead a bit harder! Age has apparently numbed my brain more than I realized. In my view, the QRM fighting tools of the K3 are superior to the Orion II (filters, notch, NB, etc.), so I'm thinking this could be a very interesting (and enlightening) experiment. But it seems very likely I haven't operated either radio at their full potential. I probably also need to reassess my complement of headphones! Thanks to Bill for passing this tidbit along, and to Fred for authoring it.

From K3ZO many time winner of Dayton pileup contests: I just got back from Thailand so am reading all of this old discussion for the first time, but as an Orion owner, and since someone mentioned me in a post, I thought I ought to comment. I have always preferred to use the filters between my ears rather than the ones that come with radios and never liked narrow filters because the ringing bothers me a lot. N3UM and W4AU convinced me to go with the Orion mainly because they said it doesn't ring. Well in my opinion it does, but you can zero out the ringing by using a bandwidth of exactly 970 Hz, so when I'm on CW that's where my bandwidth is always set. Precisely because in a DX contest I had a loud W2 perch 670 Hz above me and used the Orion's very FB notch filter to notch him out, I now also use the notch filter set for 670 Hz tone and 300 Hz bandwidth full time while on CW, because in the Orion the notch filter appears to the user to act like another filter in series with the regular one. This combination has given me reception pleasure like I haven't had for years (maybe my Drake R4C with the Sherwood mods got close way back when). Nevertheless taking Tom's main point, narrowing a filter mainly so you can squeeze up right close to another guy running on an adjacent channel is not a good reason to use a narrow filter. In my experience you always want to know what is going on around you as you run. Narrowing the filter beyond a certain point deprives you of the audio version of peripheral vision, and you lose if you cut yourself off from what's going on around you that way. Tom is right when he says that it will lower your rate even though you think you're really banging away. With a rig like the Orion the tone you set your sidetone monitor to is also very important. I like to copy CW at 400 Hz, and I have been surprised when people have commented that 400 Hz is a much lower tone than they like to use. I believe it is established science that the lower the tone you use to copy, the better your ear is at separating out tones which differ in frequency very little from each other. I actually thought I was using a rather high choice of
RE: [Elecraft] K3 CW Rx Audio
Paul, I hate to disagree with you and others but, I would not want the DSP to go any wider than 2.8 KHz in CW unless there is a way to limit the DSP to the width of the enabled filters. As it stands now, if the radio has 12 or 6, 2.8. 1.8, 500 and 200 filters installed - the CW DSP goes out to 2.80 even if FL2 (the 2.8) is disabled. That leaves a lot of useless cranking on the width control. IMO, extending the DSP bandwidth in CW should be done only if accompanied by restricting the maximum width to that of the widest ENABLED roofing filter. 73, ...

The K3's CW receive bandwidth is presently limited to no greater than 2.8 kHz, even when the optional 6 kHz filter is installed. At the moment, the DSP is the limiting factor. I would rather not re-visit the rationale for wanting a wider CW receive bandwidth as that is covered in detail within the list archives. The procedure that I described is a means of opening up the receiver beyond 2.8 kHz while being engaged in a CW QSO. Simply put, it allows the use of SSB mode with an offset for CW reception (VFO A), while using CW mode ( on VFO B) for transmission. 73, Paul, W9AC - Original Message - From: Bob Cunnings [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Monday, April 21, 2008 10:27 AM Subject: Re: [Elecraft] K3 CW Rx Audio Ok, as it is now you can open up CW rx all the way to 2.8 kHz if you like with the 2.7 kHz filter installed - and *enabled* for CW mode.

With that suggestion, the entire procedure I mentioned (including split recall) is now automated by saving into memory. (almost like a macro?) Even better, by activating SPLT SV as you mentioned, one can band hop and go right back to the saved split settings without having to recall the memory. For example, I had called the CW Rx split procedure as I described for 40M -- then tuned around on 20M SSB for a while and came back to 40M where all settings were brought back with the just the band change button. Even tried powering down the rig, and all settings came back at power-up. Probably the only distraction with the procedure is that the lower, smaller frequency display becomes the real operating frequency for CW off-set purposes. Oh, and CW spot will not work this way either. So, opening up the DSP filters in a future f/w release for CW Rx mode is still the preferred way of accomplishing this. Still, the flexibility to accomplish this in the K3 and still retain all the QSK attributes is damn impressive.

[Elecraft] K3 rx audio: who's on first?
Dave, W7AQK sed: If I read it right, Bill, W4ZV, is responding to Doug by quoting Fred! Yup...that's right! The problem here is lack of a data dictionary. Fred calls wide for cw as just under 1kc. I do too! My operating style is well documented on many reflectors and I like a wide cw filter for most contesting also. I'll use narrow when called for (400-600hz). Maybe I'll use 200 hz a couple time per conetst...maybe. When contesting and doing S+P, especially on 40m here on the East Coast when the band is hot to EUR, I will crank down the BW to narrow and walk the band from bottom to top. It never ceases to amaze me how I can call some gnat signal which would normally be covered by a loud, close station unless I used a narrow filter, and the guy will return my call. Clearly, he is not hearing the loud guy as loudly as I am (if at all)...and he must also be wondering why he isn't getting a lot more calls. :-) My initial reaction to suggestion about using SSB filter for cw was that wide must be 2.7 or 2.8khz, which is just too wide for me unless you're on a very quiet (meaning the opposite of crowded) band. To me, a wide filter is lets in too much noise which is what I find to be fatiguing (different strokes, apparently). Now we learn that even 2.8khz is not wide enough on cw for some. Go figure.

[Elecraft] K3 Main/Sub audio routing
If I'm reading the K3 manual correctly, there are limitations on how audio from the Main and Sub receiver can be routed to the headphones. The way I read it, if Sub is off, audio from the Main receiver will appear in both the left and right headphones. If Sub is on, audio from the Main receiver will appear in the left headphone and audio from the Sub will appear in the right headphone. Is this correct, and are these the only audio routing options? If so, is this something that can be changed in the firmware, or is it a hardware limitation? I ask because there are two alternative audio configurations that are highly desirable, at least for me: 1. If Sub receiver audio can be routed to *both* headphones, I can utilize a second RX-only antenna. I can connect the first RX-only antenna to RX ANT and listen to it with the Main receiver. I can also connect a second RX-only antenna to ANT 2 or AUX RF, route that antenna to the Sub receiver, route Sub audio to *both* headphones, turn off the Main receiver volume, and listen to the second RX antenna only on the Sub receiver. This configuration takes advantage of having two identical receivers. 2. When chasing split DX, I like to put the DX station's audio both headphones and the pileup in only one headphone (usually the right, if the pileup is up.) That way, it's easier to hear the DX station when it comes back to a caller. It looks like I might be able to select alternative #1 by doing the following: 1. Set CONFIG:SPKRS to 1 (force mono) 2. Set CONFIG:SPKRS+PH (enable simultaneous speakers and headphones) However, the manual is not clear on two points. First, it says that CONFIG:SPKRS=1 disables the right channel. Is that true, or does it mix the left and right channels together so Sub audio can be heard through a mono speaker? Second, it's not clear whether CONFIG:SPKRS+PH only enables external speakers or also enables the internal speaker. If so, I guess a plug could be inserted in the external speaker jack to disable the internal speaker. This is not as simple and intuitive as flexible audio routing, but it's better than not being able to utilize a second RX antenna. Note that both alternative configurations can be selected on the Orion, which allows audio from either receiver to be routed to either or both headphones. It isn't practical for alternative #1 because the Orion Sub receiver is quite inferior to the Main receiver. But it can be used for alternative #2. 73, Dick WC1M ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 antenna routing
In reading the manual, it seems that the Sub receiver can't use the RX ANT unless the receive antenna is connected to both RX ANT and AUX RF with a Y-cable, and KRX3 is set to NOR:ANT3. This allows the Sub to use the RX ANT for diversity reception, but eliminates the ability of the Sub to use any other antenna (such as a second receive-only antenna) for diversity reception. Is this correct? If so, I'd suggest a future mod to make antenna routing between the Main and Sub receivers more flexible (and less confusing.) The Orion antenna selection matrix is a good example to follow. Complete flexibility in antenna selection will allow the user to take full advantage of having two identical receivers. 73, Dick WC1M ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Main/Sub audio routing
Charles In a mono audio situation, you could connect a 100 ohm pot as a balance control fairly easily. Connect the hot leads to each ear piece to the ends of the pot, and connect the hot lead coming from the radio to the pot's wiper. Now as you vary the pot, more audio will appear in one earpiece or the other. If you have a lot of audio power, you might want to use a pot good for a watt or more, just to keep it from being heated by excess audio power. For headphone use, I wouldn't think this too likely though.

Re: [Elecraft] Benefit of excessive bandwidth?
Darwin, Keith wrote: By excessive, I mean having the DSP bandwidth wider than the roofing filter. What benefit is there? Do you really get that much more wide band data downstream from the roofing filter? So far I've pretty much just forced myself to stay at or below the bandwidth of the roofing filter. Practically speaking you're correct. However, I set DSP WIDTH much wider than the roofing filters when I measure their bandwidth so the DSP bandwidth doesn't interfere. Similarly you need to always select a much wider roofing filter than the DSP filter when you measure the latter. You have to override the automatic roofing filter option when making measurements like this. This can be done by enabling ONLY the roofing filter you want in the filter configuration menu. 73, Bill -- View this message in context: http://www.nabble.com/Benefit-of-excessive-bandwidth--tp16815905p16817484.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 with SteppIR
Is anyone on the reflector using their K3 with a SteppIR antenna and a logging program on their computer? I'm hoping to build a cable to unite my K3 (due in May or June) to the SteppIR box and the computer running Logger32. My Icom IC-756PRO just parallelled the CI-V cable from the radio to the SteppIR box and the serial port on the computer. I'm pretty sure the K3's not going to be that easy. Since the K3 is outputting to a serial port it sounds easy to connect to the computer's serial port but I don't quite see where the SteppIR box interfaces into the picture. Has anyone already plowed this ground? Any help is appreciated. 73, Jim - K5LAD It's so simple to be wise.

RE: [Elecraft] K3 with SteppIR
Jim; You'll need a serial Y cable. They can be had online and SteppIR sells one too. I have the one from SteppIR. The cable runs from the serial port on my K3 to the serial port on my PC. The other segment of the Y runs to the upper-most serial port on the SteppIR controller. I have the SteppIR controller set to KENW mode and 4800 baud. I'm using XMLog by W1ECT. XMLog is set to Kenwood TS-2000 mode. Keep in mind that the SteppIR controller is just a passive listener on the serial line. It does not send serial commands. It only responds to commands it overhears being sent between the rig and PC. Also in the K3 CONFIG menu, you may want to set AUTO INF to Auto 1. This causes the K3 to send a band/frequency data on the serial line every time you change frequency. Some log book software polls the rig continuously which lets the SteppIR track your band and frequency changes automatically. XM Log does not do this but setting AUTO INF to AUTO 1 accomplishes the same thing and my SteppIR follows as I QSY.
