Re: [Elecraft] K3: Using the K144XV to drive higher microwave transverters
Yes. The trick is to set the XVxADR config item to either Int. trnX for internal 144 IF use or trnX for the external 28MHz transverter. Both can be set to display the same or different RF dsiplay frequency. Setting Int.TrnX always uses the 144 internal transverter. The choice of the value of X in Int. TrnX is for external band decoder type use. In my case I use my XV144 external transverter along side the Internal 144MHz tranverter. Great for perforamnce comparisons. I also use the internal xverter as the 144MHz IF for my DEMI 903 and 1296 units. I use the KRC2 band decoder to sort out my PTT routing from the K3. I also have the XV222 and XV432 in my stack, all controlled through the KRC2 along with amps amd mast TR relays. - Mike -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Using-the-K144XV-to-drive-higher-microwave-transverters-tp7331198p7331991.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] 144MHz
I have run my XV144 and the internal k144XV side by side on the same and different antennas (one with a mast preamp) to see if there was any performance advantage between them, and decide if I should sell my XV144 as now extra equipment. Lots of A/B switching listening to our 2M weak signal nets and a few contests and I have concluded there is no RX performance difference to my ear, some internal spurs on the internal transverter, but nothing that affects me, and the TX power is 7Watts out internal vs 20W out on the external transverter. I have a 10W in 2M amp so 7W is good enough, and the internal covers the FM portion of the band. I also used both to drive my 903 and 1296 transverters and they both worked great. So my XV144 external sits lonely now. Advantage goes to the Internal as I have the K144XV reflock option and the K3 hi stability TCXO option so it is dead on up to 2M. - Mike -- View this message in context: http://elecraft.365791.n2.nabble.com/144MHz-tp7316179p7332022.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Denny, Adjust the trimmers for maximum power. If the power goes above 5 watts, bring it down by repeatably tapping the WPM- button or exit TUNE and set the OUT menu to a lower value. Remember that you are adjusting for a peak - and if the power output goes too high, you will not be able to see the peak of the tuning because the transistors have reached their peak capability.

Re: [Elecraft] Fwd: K1 Transmitter problem
Denny, Align them first on receive for the strongest signal, and be certain you are receiving a real signal on the band being aligned - if you do not have a signal generator, use another transmitter running into a dummy load and use a wire placed near the dummy load as an antenna for the K1. Do the 15 (or 17) meter band first, and then do 20 meters. Also, align 30 meters before 40 meters. Start with the trimmers with the slots parallel to the long side of the board - the final adjustment should be no more than 20 degrees away from that center position - if it is more, check the toroids for the correct number of turns. Of the 4 trimmers for each band, there is no particular order - just adjust them for a peak. If you have an RF Probe or 'scope with a 10X probe, you can align the pre-mixer bandpass (the two trimmers on the left edge) initially by looking for the maximum RF voltage on P1 pin 6 during receive, but do a final touch up during TX at 1.5 or 2 watts. 73, Don W3FPR On 3/1/2012 9:17 AM, Dennis Rayfield wrote: Don, Thanks for the help, I'll do them tonight when I get home.

Re: [Elecraft] K3--KPA500 Request
The KPA500 does not communicate with the K3 via the serial port, only through the K3's AuxBus so that data is not available to external devices. Don't know if the programmers could make it available or not. The RS-232 port on the KPA500 is used only for programming the firmware in the amp I am also a MacLoggerDX user... If the KPA500 knows the output power well enough to make it available on its own serial port then why can't it send that info back to the K3 through the K3-KPA500 interface. I think the original request is a one with good technical merit that could be implemented -- maybe without too much hassle by the Elecraft programmer(s). 73, phil, K7PEH On Feb 29, 2012, at 11:04 PM, Jack Brindle wrote: Jim; The KPA does not send its output power information to the K3, so the K3 would just be guessing.

Re: [Elecraft] K3--KPA500 Request
It still seems to be a useful feature. I mean, you usually only read the power level when transmitting anyway, at least that is what I do. So, this is how it could work that would satisfy me. Given a K3 power setting, the output power of the KPA500 is read when transmitting which can be saved in memory on the K3 and thus available via the programming interface. If the K3 power setting is changed, or other changes such as band changes and so on occur, then this KPA500 power setting can be cleared to zero until the K3 transmits again using the KPA500 and thus getting a new value. Not a perfect solution but it seems to be able to work in most situations. phil, K7PEH On Mar 1, 2012, at 6:41 AM, N2BC wrote: The program is reading the power SETTING on the K3 - not the K3 output power - is available regardless of mode or if the K3 is transmitting or receiving.

Re: [Elecraft] K3--KPA500 Request
It seems a bit more information is needed here. First, communications between the K3 and KPA is essentially one-way - it goes from the KPA to the K3. While that is the right direction for this kind of information, we run into a problem rather quickly. Auxbus communication tends to be slow and very disruptive to the K3, especially during transmit. We send a minimal amount of information to the K3 in order to avoid problems (none during transmit). It would take major modifications to the Auxbus protocol to move this particular data to the K3 (more and longer data packets), breaking the not during transmit edict. The results would not give a satisfactory user experience. The serial port on the KPA does have this information available (note to W0EB, take a look at the KPA Programming Reference at the Elecraft site) and is the right place for a computer to obtain the info. Using an additional serial port to communicate with, and control, the KPA is actually a good thing - very useful information is available, and you never know when we might release an update (ok, probably not very often). I am also a Mac person / developer. My Mac mini has a four port FTDI adapter attached. I use three of the ports in my station (so far). One for the K3, a second for the KPA and a third for my KRC2. This allows me to monitor and control my station very well, without encumbering the individual components (notably the K3). How hard would it be for Don to add KPA500 support to MLDX? From my (extensive) experience in Mac development, it should not very difficult at all. You just need to talk him into adding it. Or use W4SMT's fine KPA500 Utility available at the Elecraft web site. It will monitor the KPA quite nicely in a window independent from MLDX. Of course it won't log the power level for you in the MLDX log - only MLDX can do that. I hope this answers your questions, and explains why the information is not available. At Elecraft we are all about User Experience, providing the best possible. Wayne and Eric have instilled that in not just the products but all the people of Elecraft. We do all we can to make sure things work the way they are supposed to.

Re: [Elecraft] K3--KPA500 Request
Yep, and therein lies my problem - I don't write anything - it's all in an electronic log! :-) So, after making a bunch of QSO's (think contest) I have to (1) leave each log entry incorrect with a 25W power or (2) manually double-click in the power field in each log entry and enter the actual power. Option number one wouldn't be too bad if I always operated QRO - I could simply try to remember that any time I see a power level of less than 40 in the MLDX log, I was actually running high power - of some sort. But, I often do run the K3 barefoot, and for local contacts, the power might actually be set to 10 - 30 watts.

Re: [Elecraft] OT: Need Antenna Tuning Help
I think you have to identify which of the two resonances is due to the antenna and not due to the antenna + feedline. Elevated radials that exhibit resonances of their own can also be confounding. The multiple resonance may be due to a fortunate length of coax that presents a 50 ohm at the shack end. You can identify which resonance is due to the antenna by attaching a short length of coax at the antenna feed and find the resonance with your antenna analyzer. Then you will know if you have to add or subtract wire. The fact that SWR goes up when you keep adding wires (@ complex part =0) only means that the impedance at resonance is changing. At resonance (complex part=0) different antennas have different values of Z Inverted L's and verticals have Z's of 30 to 35 ohms at resonance with a really good ground system. That isn't an SWR of 1:1.A yagi may have a Z of 15 ohms-- hence a big SWR. Once you have the antenna resonant where you want, then you have to deal with the mismatch. A simple L network at the base of the antenna will take care of the mismatch. 500 watts doesn't require monster components. 73 de Brian/K3KO On 2/28/2012 7:20 PM, Don Wilhelm wrote: Jim, I did a little chatting with Guy K2AV when he was starting to work on that project (W0UCE lives only a few miles from me), and I recall that changing the height above ground changed the behavior.

Re: [Elecraft] K3--KPA500 Request
Jack, The power level MLDX sees appears to be updated / polled every few seconds. And, it stays the same, regardless of the K3's Power level setting. A few minutes ago I sent Don an email asking if he had been following the thread. He replied no, but asked for a link to it. I just sent it to him. I do like MLDX - a fine program, indeed. Not only do I use it for my limited contesting, but - I am making an assault on 5BWAS. Being able to quickly key in a station's call and finding out if it is a state I need on that band makes things lots easier. Certainly I could use native QRZ.COM, but with MLDX, if I need the state, everything is already loaded into the proper fields for me. I got into IT back in the late 60's and have enjoyed knowing quite a few programming languages - mostly dinosaur-speak by today's standards. But I know what you mean about support hassles! I did write a small Apple Script program that I have been using to key in my past 47 years' worth of paper logs and enter them into MLDX. Now THAT has been quite a chore! Jim / W6JHB On Thursday, Mar 1, 2012, at Thursday, 9:09 AM, Jack Brindle wrote: Jim; Let me ask another question. For logging the power level, what gets logged? During transmit, the KPA is constantly measuring its output power, making it available to a computer in response to a serial command query. The measurement can vary widely, depending on when the measurement is taken with respect to the transmission. Especially in SSB, this can be anywhere between zero and the peak output. Just watch the KPA power display to see this action. A logging program would periodically poll for the power, and will receive many readings during a QSO. So the question is, which of these readings would it log? Perhaps the highest one it received? Or should it keep a running average? We don't want the complexity of this calculation to get out of hand, especially when asking a logging program author/vendor to add the feature to his product. But it is necessary to be able to add the feature. I believe the value set in the K3 when you twist the power knob is the peak power that will be allowed during transmit, but it, too, is not what is actually transmitted. With the KPA, we only have a measured value, which is approximately 13db higher than whatever the transmitter feeds it. Note that we cannot control the output power in the KPA other than shutting off amplification. I sent Don an email asking if he is interested in adding KPA support to MLDX. I've know him for quite some time, and am quite willing to work with him if he decides to support the feature. Interestingly, I'm not an MLDX user (something Don would like to change). The reason is that I am also a Mac developer, and have my own logging program that I use. It is constantly changing, and not a commercial product (Been there with MacPacket years ago, I don't want the support hassles). Besides, the reason it keeps changing is that I'm not really happy with it yet. And no, it doesn't have KPA support at present, nor many of the features that MLDX has. It is oriented towards contesting, something I really enjoy when I can break away from product development.

What I wind up with in my log is incorrect. For example, if the KPA500 is in OPERATE mode and I log a QSO, it'll get reported as a QSO made using 25 watts or power, instead of the 450 - 500 that the amp is putting out. Since the K3 and the KPA500 speak the same language and talk to each other, can the firmware be changed so that the K3 sends corrected Power Out level to the output data port when the KPA500 is engaged? As it is now, I have to go back into MLDX after every QRO contact and change the power field to reflect the actual power and not the K3's driving power.

Re: [Elecraft] K3--KPA500 Request
This post gets to the heart of the matter. The KPA500 does not have a power setting. It is a binary situation: Operate or Standby/Off. Power out is dependant on the K3. To report its power the KPA500 would need to know the power setting of the K3. If the K3 would report the status of the KPA500 the Logging program it would be able to know if the KPA500 was in operate mode. If so assume QRO. If you need to know more the logging program would need to know three things. Is the KPA500 in operate mode? If yes then what is the power setting on the K3 and what is the gain of the KPA500. This last item would need to be an enterable value in the logging program configuration. If you only want to determine QRO-QRP status then knowing that the KPA500 is in standby/off status and the K3 is under your max QRP power should do. Bottom line is can the K3 be made to report KPA500 status?

[Elecraft] 144XV with PPL Ref Osc Option
Can some one please point me in the right direction? I'm trying to calibrate the 144XV with the reference oscillator phase lock option (ROPLL) installed. The symptom is simple. When I attempt to do the (updated) frequency calibration on page 19 of the 144XV manual I get a N/A response, rather than a REFLOCK response. I'm tapping the 0 key many, many times. I get N/A and after a short wait it goes back to displaying the CONFIG option selected: XV1 OFS. I have verified the ROPLL option is installed by going through the process detailed on pages 9 and 10 of the ROPLL manual. The firmware install worked fine. I do get a B001 response as intended to the B command. The 144XV status light is well behaved, blinking only once or twice at power-up (except when uploading firmware to it). There appears to be conflicting information between the two manuals. The ROPLL manual tells me to recalibrate the XV144 on page 11 by doing arithmetic on the K3's CONFIG: REF CAL value. The XV144 manual, as amended, on page 19 tells me none of that is necessary, and just to go to CONFIG: XV1 OFS and tap the 0 switch until you see REFLOCK on the K3's LCD.

Re: [Elecraft] high-power tuner
Just curious ... have you ever measured the loss in the tuner? Most of the MFJ tuners tend to rank pretty low in that respect. Presenting a usable load to the amplifier does not in itself make it a good tuner. 73, Dave AB7E On 3/1/2012 11:16 AM, W5RDW wrote: Ditto on the MFJ-998 autotuner.

Re: [Elecraft] K3 amplifier board gold header mod
We are working on instructions to go with the kit. Here are some for now to get you going. Keith The female connectors are already gold plated. But they get damaged and should be replaced anytime the male connectors are damaged. Or replace the KPAIO3 board. The male connector pins can be heated well and then pulled out through their plastic carrier one by one. Use a little extra solder to speed the heating and removal process (you can remove it later). You can replace just the 6 male pins of the connectors at P68B on the KPA3 and at P67B on the RF board that carry the 12V current to the KPA3, if they are the only ones that look to be damaged. But do check the female connectors too for signs of high heat, oxidation, and pitting. You can remove the plastic carrier as with the female connector, to make it easier to get the pins out one by one. Then vacuum out the remaining solder and use desoldering braid to finish the job, followed by a good cleaning with Q-Tips (cotton swabs) or a cloth moistened with acetone, alcohol, or flux solvent. Take extreme care to not damage the PCB or any nearby parts either. Get the connector pins out first, then remove the solder from the plated through holes. This works better in most cases than trying to remove the connector intact unless you are truly an expert at desoldering and have the best desoldering tool made. Make sure there are no solder bridges remaining between pins and the board is in good shape before installing the new connectors. Inspect it well under a bright light with a magnifier. You should have good desoldering skill and a good desoldering station like the Pace, Weller, Waasco, Xytronic, OK/Metcal, Aoyue, etc.) or a Hakko 808 desoldering gun to do this work. Clean the desoldering tool well before starting so it works as well as it can.

[Elecraft] K2 -100 For Sale
Everyone, I guess I screwed up when I first posted my first K2 sale posting Today. My K2 is a 100 watt unit with serial numbers in the 5000 area. The amp is in the top of the K2's case while the coupler is in it's original case and serves as the base of the K2. Internal devices include the KSB2, KNB2, and digital signal processor unit (KDSP2). It works fine and is in a non smoking environment. Only issue is sometimes the KDSP2 might not come up when first powering up the radio. The fix is to power cycle the k2 and the DSP unit boots and works fine. Asking $800.00 or any reasonable offer. Shipping depends on buyer's location and offer made. Reason for selling the K2 is purchasing a KX3 and need the money. 73 Dave KD1NA __ 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] Call for Elecraft CW Net volunteers
Good Afternoon, I now have power back on again but the trees are still unloading snow and branches onto the power lines. I may not have power for long. Last night the snow was heavy on the trees but then it changed to rain which made the trees start to crack and fall. My new antenna, a little over a month old, is now in at least three pieces. I have not yet found all of it in the knee deep snow. From the broken ends it looks like it will be easy to fix once the snow disappears. Without an antenna it is tough to run the nets. Is anyone interested in trying their hand at net control for either or both of the nets? It would be nice to have more than one on each band so more of the continent is covered. However, one op will be just fine. Thank you, Kevin.

[Elecraft] Power output on higher bands
I've noticed some weirdness with transmitting on higher bands on my elecraft. Down on 40, and 80, its great. When I transmit the RF meetings goes almost all the way the up. My w2 responds and shows a good output as well. However on 20, 15, 17, the RF meter won't even get over 50, it shows maybe 1 or 2 bars at peak. Now my SWR on 20 is 1.6 so I assume that it will put out less power but not that big of a loss. I also get a hi Curr on 20 when i hold down the xmit/tune button and transmit that way, even though I am putting 14.5 v into the k3. It shows 12.6v during transmit. I do show the meter as showing it drawing almost 23 amp during transmit on 20, the rest of the bands are about 14amp. Again these readings are measured when i hold down the XMIT button. On 10m i get a 1:1 swr match, and it does the same thing, barely no RF output. So I am not convinced its a SWR match thing. Have I missed a setting somewhere? Somewhere that I have to turn this up.

I do show the meter as showing it drawing almost 23 amp during transmit on 20, the rest of the bands are about 14amp. Again these readings are measured when i hold down the XMIT button. On 10m i get a 1:1 swr match, and it does the same thing, barely no RF output. So I am not convinced its a SWR match thing. Have I missed a setting somewhere? Somewhere that I have to turn this up.

Re: [Elecraft] Power output on higher bands
Mike, Are you transmitting into a dummy load, or into an antenna. If you are transmitting into an antenna, I have to ask - what are the characteristics of your antenna on each band that you make reference to - I need to know the resistance and the reactance, not just the SWR. 73, Don W3FPR On 3/1/2012 8:04 PM, Mike Anderson wrote: I've noticed some weirdness with transmitting on higher bands on my elecraft.

Re: [Elecraft] Having trouble assembling K2
Richard, I believe I can help (even if I am 10 years older than you and have my ARRL 50 year pin). If you want to try troubleshooting by email, that is at no charge. If you would rather send it to me for repair, I will email you a form containing the information I need to properly service it. If you prefer official Elecraft repair, please contact Madelyn in the Elecraft sales office made...@elecraft.com to obtain an RSA number. The K2 kit contained the parts to assemble an RF Probe. If you have a DMM and build the RF Probe, you can do most of the Transmit Signal Tracing detailed in the back of the K2 manual. 73, Don W3FPR On 3/1/2012 7:07 PM, w8te wrote: Hello, I am Richard Ackerman, W8TE.

Re: [Elecraft] cut off
I agree with Don. Third party advertisements have no business in this list. If you are adding them, as a signature they should be removed. If your e-mail provider is adding them, you need to find a different e-mail provider. There are quite a few free POP3 and WebMail providers that do not add advertisements to outgoing e-mail. 73, ...

Re: [Elecraft] cut off
Might I suggest that gmail is a suitable alternative. Free and no offensive added content. Juno might want to take some pointers from Gmail even though Juno has been around longer.

[Elecraft] OT: SPAM, E-mail providers, etc.
Rose ... the bag lady (:-) ... lost an unknown number of customers several years ago when our locally-owned ISP dropped their SPAM filtering in a cost-cutting measure and her replies to customers beagn to have ads (Viagra) attached. It was only when an irate cutomer complained that she /we became aware of what was happening. We've learned to be very cautious of incoming messages from the free e-mail providers. Nothing is free (;-) Our several g-mail accounts have been completely trouble- free. FWIW, we simply don't receive SPAM ... none. 73!
