Re: [Elecraft] "random wire" and the KX3 ATU
Thanks, Mike. I noticed Jack VE3EED made his calculations using the band center. Out of curiosity I just write a little C program that uses band edges and converts them to half wavelengths. I plotted the overlapping "red zones" and, if I didn't make a mistake, came up with slightly different safe lengths. The graph and C code are at http://udel.edu/~mm/ham/randomWire/ Let me know if you spot errors in the code!

Re: [Elecraft] K3/KX3 Operating Tip: APF (audio peaking, filter) for weak-signal CW work

Re: [Elecraft] Firmware final?
CW decoder worked fine for me on field day. and since I still have the CW training wheels on, I sure needed the help. CW decode THR at 3 and speed at 30-90 (I think what ever is the higher setting) this decoded fine with speeds well below 30.cant remember exact AGC settings but fairly high threshold for CW. I do tend to set AF gain to one level and use rf gain for good listening level this also helps the cw decoder by keeping noise down.

[Elecraft] Field Day experience with K3
Fellow K3 guys: N6L, our 2AORG solar powered Field Day station was specifically configured to demonstrate off-the-grid emergency opperations and thus provided an excellent opportunity to put one of my two K3 (sn 3271 and 2215) to work under less than the comforts of home. Disquietingly, the K3 wasn't up to the task! Let me explain: both the K3 and our second radio, a TenTec Eagle (Model 599AT sn 3051271430) were fed from the same 120 watt Power Film Panel /110 AmpHr GSM battery combination and operated at 100W output. In tandom operation, the Eagle was not affected by momentary voltage dips (below 10 VDC) whereas the K3 would shut down. With both radios in SSB mode and following the first K3 shut down, the K3s operating environment was changed: different bands, different antennas, reduced power output (to 10 watts) different operators and, finally different solar /GSM battery combinations. None remedied the problem. Following from our experience, while the K3 and the Eagle offer excellent operating characteristics, beware of the K3 under extenuating circumstances; it's liable to let you down even at low output power levels. The only potential solution may be found in a voltage boost device such as the "N8XJK boost regulators" http://stores.tgelectronics.org/Categories.bok?category=Boosters Unfortunately, following the research necessary to uncover a source of these devices Field Day was over.

Re: [Elecraft] kx3 options shipping status
I decided after the fact to order the paddle and mic. Since I was ordering a K3, I asked if they could be included with that order, rather than waiting for the KX3 to ship. At that time, probably 60 or so days ago, I was told that the mic would ship with the K3, but they were saving the paddles to ship with units ready to go. That situation may have changed.

Re: [Elecraft] Field Day experience with K3
John The fact that the voltage dropped below 10 volts DC causes me to wonder about the either the adequacy of the wire size used (for the distance involved) or the tightness of the connections to the battery. A 110 AH GSM battery should not drop that much with even 2 100 watt radios drawing current from it. The fact that the K3 is designed to shut down when the voltage gets too low is a good point in its design IMHO. 73, Don W3FPR On 6/28/2012 1:19 PM, John Kountz wrote: > Disquietingly, the K3 wasn't up to the task! > Let me explain: both the K3 and our second radio, a TenTec Eagle (Model > 599AT sn 3051271430) were fed from the same 120 watt Power Film Panel /110 > AmpHr GSM battery combination and operated at 100W output.

Re: [Elecraft] Field Day experience with K3
The problem here isn't the battery AH capacity, but the voltage supply. It could be dropping below 10 vdc because both radios are on the same supply, or because the power supply wires are too fine gauge, or because the battery is defective. The K3 is less robust to supply voltage than the other Elecraft radios. The K2 is rated for 10-15 volts; the K1, KX1, and KX3 go down a lot lower, I think 8 volts. I looked at the K3 documents to see what minimum voltage it requires, and I couldn't find it -- I think it's something like 11, but it may be 11.5 or even 12. You'd probably do fine just by using a separate battery for each radio, and not letting it run down too far. A voltage booster isn't needed, as lots of operators all over the world have demonstrated.

[Elecraft] KX3 and NaP3
Now that Field Day is over, I've had a chance to play with my KX3. I have NaP3 running with my KX3 and using an E-MU 0202 sound card with my laptop. It's a real WOW! I have a panadapter, effectively, and I can play with the PowerSDR filters that are a part of NaP3. NaP3 follows my tuning of the KX3 or I can click on a signal and have the KX3 move to it. It is a really useful adjunct to the overall capability. The only thing I've had a problem with is the IF offsets. They are different for each mode, and not by a little. Unfortunately, NaP3 doesn't remember the offsets by mode. However, I still like the match up and suggest KX3 owners have a go at trying this. The offset issue can be addressed by noting them and putting them in manually, at least for the time being. Having the receiver I/Q available seems to have proved a seriously good idea. 73, Barry K3NDM __ 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] Field Day experience with K3
The K3/10 will run down to 9.0 V or so -- much lower than almost any other desktop transceiver. Of course available power output will drop at such low voltages. The K3/100 needs 11 V to make 100 W on most bands (and higher on some bands), but it should not shut down completely until you hit that 9.0 V level. The radio will automatically reduce power (or drop completely out of QRO mode, bypassing the KPA3) as required. If you notice any "interesting" behavior other than what I described, let me know. 73, Wayne N6KR On Jun 28, 2012, at 11:07 AM, Peter Wollan wrote: > The problem here isn't the battery AH capacity, but the voltage > supply.

[Elecraft] KX3 BETA firmware release (rev 1.06) -- major improvements in all areas
KX3 beta firmware rev 1.06 (with DSP rev 0.92) is now available. This is major update from the current production release (0.99). The release notes for 1.06, below, show all changes since rev 0.99, organized into new features and bug fixes. Dozens of volunteers have been pounding on intermediate field-test releases for several weeks -- thanks, guys. You'll need the KX3 Utility application to download and install firmware. For full instructions, refer to our KX3 software page: http://www.elecraft.com/KX3/KX3_software.htm We recommend that all KX3 owners install the new firmware. We hope to promote it to a full-production release on Monday. Thanks, Wayne N6KR * * * MCU 1.06/DSP 0.52, 6-28-2012 NEW FEATURES (since rev. 0.99): * AGC IMPROVED: AGC attack/decay now uses precision log/antilog functions (same as in the latest K3 firmware release). * NOISE PULSE REJECTION: The KX3 can now detect high-amplitude noise pulses (as from appliances or florescent lamps) and remove them before they pin the S-meter. To enable this feature, locate the AGC*THR menu entry, tap ‘6’ (DLY ), and set AGC PLS to NOR. * AUTOSPOT TUNES RIT: If RIT is on, AUTO-SPOT fine-tunes only the RIT offset, leaving VFO A’s frequency untouched. (Auto-spot applies to CW and PSK-D modes; it is enabled by turning on CWT. Tap SPOT to auto- spot.) * VFO TUNING NOISE REDUCTION (VFO NR and RX SHFT): Both the VFO NR and RX SHFT menu entries can be set per-band. Using them together virtually eliminates VFO tuning noise. This is typically needed only on 6 meters. Note: With RX SHFT set to 8.0, dual watch is not available on that band. This restriction will be removed in a future firmware release. * TX COMPRESSION DISABLED in DATA-A and AFSK-A modes. * RX EQ AND TX EQ DISABLED in DATA-A and AFSK-A modes. * CW TEXT DECODE IMPROVED: CW text decode now includes a user-settable threshold, improving copy and better rejecting noise. To turn on CW decode: Hold TEXT, then rotate VFO B to select a receive signal threshold (RX THR1-9). For weak signals, use low thresholds (RX THR1-3). With strong signals, medium thresholds (RX THR4-6) provide better copy. At very high code speeds, the highest thresholds work best (RX THR7-9). Next, turn on CWT (CW tuning aid). Tune VFO A until the middle CWT segment flashes in time with the incoming CW. If necessary, further adjust the RX THR level to provide best copy. Tips: A narrow bandwidth setting (0.1 to 0.2 kHz) should be used if the band is noisy. Signals with a good signal/noise ratio and well-spaced CW elements will have the lowest error rate. When the KX3 detects a non- Morse character code, it displays an asterisk (*). * MORSE CODE AUDIO USER INTERFACE CHANGES: MENU:SW TONE can be set to CODE nn (where nn is the desired code speed) to provide CW feedback on all controls. This is intended primarily for use by blind operators. Enhancements: Tap DISP to hear the operating mode followed by the kHz digits of the VFO A frequency (e.g., if you’re on 14040.0 CW, you’ll hear “C 040”). Changing bands or recalling a frequency memory sends the MHz digits as well (e.g. “C 14040”). Most of the rotary controls now report their settings (DLY, CMP, KEYER, MIC, PWR, and MON). Many additional improvements are planned, as well as a guide to touch-only use of the KX3. BUG FIXES (since rev 0.99): * POWER-OFF/ON SWITCHING: We’ve seen a few cases where the KX3 could not be turned on after being turned off. This should no longer occur. * AUTO-SPOT now works correctly even if coarse VFO tuning was in effect. * UNEXPECTED PREAMP TURN-OFF when some controls were used: fixed. * INTERMITTENT TX ALC BAR GRAPH LEVEL: fixed. * LOSS OF RX AUDIO IN SSB MODE @ BANDWIDTH ~2.40 kHz: fixed. * TX EQ now works correctly. In some cases it was having no effect. * DUAL WATCH BUG: The dual-watch feature was staying partially engaged at all times with DUAL RX set to AUTO, even when VFOs were tuned out of dual watch range. This resulted in some “ghost” signals at certain offsets. Fixed. * MANUAL NOTCH is no longer turned off when you “normalize” the passband. * FREQUENCY MEMORY FIXES: A channel-scan group can now include memory #00. Also, recalling an unprogrammed memory no longer locks VFO A. __ 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] Field Day experience with K3
Let me make sure I understand this correctly. Your K3, which is spec'd for a minimum operating voltage of 11 volts, is somehow "not up to the task" because it doesn't work properly at voltages less than 10 volts. I look at it differently. Your power source was clearly not up to the task, and apparently neither was your system engineering if the power source was not capable of providing the required power under the circumstances at hand. At first glance, I'd be surprised if you were getting anything even close to 120 watts out of that solar panel since they are spec'd for full sunlight conditions that rarely hold up on a continuous basis (been there, done that), so even a voltage booster isn't going to function very long when you're draining enough current to feed two rigs at 100 watts.

Re: [Elecraft] Field Day experience with K3
If your supply voltage is too low for a given application, I suggest dropping TX power. In the case of PSK31, which works well at very low S/N ratios, I suspect 50 W would have worked just as well as 100 W for 99% of contacts. 73, Wayne N6KR On Jun 28, 2012, at 11:54 AM, Elecraft K3 wrote: > I would not want to be running an IMD sensitive mode like PSK with > 11 V. > > We came close at our location a few times between generator runs - > 11.3 V or so and my outboard IMD meter still showed an acceptable > signal - IMD -25db or less. > > 73 de Eric, KG6MZS > > On Jun 28, 2012, at 11:44 AM, Wayne Burdick wrote: > >> The K3/100 needs 11 V to make 100 W on most bands (and higher on some >> bands), but it should not shut down completely until you hit that 9.0 >> V level.

Re: [Elecraft] Field Day experience with K3
K3 voltage specs are 11-15Vand the Eagle spec is 13.8V +- 15% that's about 11.7V- 15.9V. even though the Eagle would not shut down you were definitely running below spec voltage and probably causing some IMD if not excessive heat. My other concern would be how low was the battery voltage getting. AGM or any wet battery for that matter should not be used when the voltage right at the battery posts drops to low. if it is you are damaging the battery. and 10V is definitely too low. At my summer cottage its solar charged battery only.when the cell voltage is near 11.4V I still get 11V at the rig at 100W keydown as I use heavy cable mostly 10AWG from the battery only 5ft away and a short 12 AWG from the distribution to the rig. The battery also runs lighting etc. Ive never had the K3 shutdown due to voltage faults. and my rule is if it goes below 11.3V at the terminals it time to go QRT and bed. The K3 shutting down is just a safety measure to prevent damage and dirty transmissions. Not a problem in my opinion, more a good feature.I hope that the other rig wasn't splattering to much at those lower voltages.

Re: [Elecraft] Field Day experience with K3
It seems to me that the solution is to improve the voltage regulation of your power system, rather than implicate this radio or that one for it's inability to follow the wide voltage swings you are experiencing. Even if Brand X "works" under such conditions, why would you want to, for the various reasons already stated? Just because my car still happens to run with 10% water in the gasoline, is it a good idea to continue to do so? Yes, it might have been an inconvenience for your Field Day 2012, but I hope for 2013 you'll have a better solution. The suggestion to reduce K3 power by 2 dB (1/3 of an S-unit) to 63 W is a good one which I have followed for 15 years, and could well solve all of your problems. Additionally, I have used a boost regulator after the N8XJK design for almost ten years and now consider it indispensable. I made 300 contacts on one 35 A-h battery and a few more on another battery. That's pretty good efficiency. Regards, Al W6LX > On Thu, Jun 28, 2012 at 12:19 PM, John Kountz wrote: >> >> ...

Igor, I'm only using the global offset. To be honest, I have only 12 hours experience with my lash up. Getting it all to play nicely on Windows 7 was a challenge. I first needed to find a Win7 driver for my sound card, and there were a few idiocies with my laptop. But, it works know, and other than the offset issue, it really is nice.

[Elecraft] [K2] Radio Owls' Field Day
I just wanted to post my own Field Day observations without necessarily starting another thread. Two things I was extremely happy about: 1/ My 13-year-old son, Simon, made almost 100 contacts by himself. He's had his license for ten months. Even Blaise my six-year-old made three contacts and was trying for more! 2/ Even though I hadn't used the K2 since last Field Day I never once thought, "Okay, I'm operating an Elecraft K2," in order to think about how to do something. Instead, I *never* adjusted a control other than the tuning knob; I can't even remember being aware of the digital display; the 'transparency' of the K2 simply left me hearing and visualizing signals without being aware of the rig itself. In short, the rig disappeared. This is a litmus test that I apply to all rigs and only two, the K2 and the Omni VI, have ever passed the test. Very cool. I'll have to re-think setting up in a rain forest next year because rain kept us off the air for all except 6 hours... but we hope to work you all from a different location in 2013.

Re: [Elecraft] Where's The Propagation?
Hi Dave, It might be worthwhile to keep an eye on 6m if you are not already doing this, you might find some S. Americans (LU, CE etc) coming through via a TEP or TEP + Es path. During most of this month stations in South and Central America have been heard here at good strength on 10m around our midnight (Z + 0200), I think via a TEP + Es path. So "things" are happening in the ionosphere :-) 73, Geoff LX2AO On June 28, 2012 at 10:07 PM, Dave W7AQK wrote: > Hi all, > > Well, I feel like the proverbial guy who is all dressed up and nowhere to > go!

Re: [Elecraft] Field Day experience with K3
You might want to get a battery booster. Here is one http://stores.tgelectronics.org/Detail.bok?no=10. I can recommend that one. Had one for a couple years and use it to boost to 14.5VDC from whatever voltage any time of day from a solar-charged battery. I think my K3 likes that 14.5V!

Re: [Elecraft] Field Day experience with K3
Guys, I think the point is this: There is a real emergency. You are off someplace with a big battery and have been operating for quite some time, enough for the battery to have gone down. You have another message to get through. In this situation, perhaps you should be running CW at a lower power, but still, the situation could be very real. Having a battery booster could be very helpful, and perhaps one should be added to the ham's arsenal. On the other hand, running 100 watts on battery is probably not a good idea either. Having been in emergency situations where you do not know when operations will end, you do everything you can to conserver your resources. That means lowering the TX power as much as possible. Even still, Murphy says that at some point when the battery is running out, someone will hand you an emergency message to get through. How do you handle it? As I noted, I'd then lower the power and grab the CW key... Jack Brindle, W6FB On Jun 28, 2012, at 2:54 PM, Matthew Zilmer wrote: > You might want to get a battery booster.

[Elecraft] KX3 - Keying problem - First Dit Going AWOL
Randomly, and always after a short period of "rest" (for example, while in QSO and listening to the other ham sending), the first 'dit' goes missing. Does *not* occur in HAND mode; only occurs when using the KX3 internal keyer. Happens at slow speeds as well as higher speeds (my typical range is 13 wpm to 25 wpm). Occurs with the KXPD3 as well as with external paddles (i.e. KEY1 and KEY2) Once sending is resumed within the QSO, it *never* happens again -- until after the next "rest" period while the other guy is sending, but it does so *randomly*, never predictably. Some QSOs proceed perfectly to the end; others get messed up. In fact, it might work fine all night and make me think it's fixed itself. Then it returns in a future session. Shot the KXPD3 with De-Oxit again. No joy. The externally connected paddles were four Begalis - rather improbable that all four + the KXPD3 have mechanical issues or dirty contacts. In fact one of them, the HST, got a good soaking of De-Oxit just in case. Each Begali has its own cord and plug so rule out a common line issue. My KX3 is #0325 and it was factory-built. I'm running with the original firmware it was shipped with. I have *not* moved to the new release as Wayne has suggested - yet - because I'd prefer to wait until the production release on Monday when the download process will be less work. This problem is about a week old now. I wanted to gather as much info as I could on it.

Re: [Elecraft] "random wire" and the KX3 ATU
In fact what you can do is just make the first 17 feet of the antenna (including counterpoise) out of ladder line or even twin lead so that it is a zepp fed W3EDP. This is what I use as my low-band antenna at home and my backup antenna at the cottage. Through a 4:1 balun I am able to get a good match on 160m through 10m with the internal tuner in my K2 and my LDG auto-tuner. It works .. I even made a few 160m QSOs with it running 5W on CW during field day. I find that it is easiest to erect as an inverted-L.

Re: [Elecraft] KX3 - Keying problem - First Dit Going AWOL
Wayne, I'm using what the KX3 was shipped with - MCU 0.99 / DSP 0.85, 5/7/2012 I will download and install the upcoming production release on Monday because I want to avoid all that computer work to download the Beta version. But you bring up an interesting thing - all of these lost dits have been occuring at my home station where my KX3 is connected through an Elecraft W2 to an SG-237 autocoupler which manages my all-band doublet at the feedpoint. I just press and hold XMIT to TUNE my autocoupler. I don't *ever* press ATU TUNE at home because that can damage the autocoupler. I don't see any menu entry to disable the internal KX3 ATU (as with my K2 for example). Page 14 of the manual states that TUNE is used for external wattmeters and antenna tuners. I've been under the assumption that the ATU is out of the mix unless I press it. It sounds like you're saying it might be jumping in on its own to tune without any action on my part? If that's true then my ATU is tuning my autocoupler.

Re: [Elecraft] KX3 - Keying problem - First Dit Going AWOL
Wayne, I found the ATU menu "byP" entry - my apologies. I could not find it in the manual and assumed there was no bypass option because the switch arrangement on the front panel seemed to preclude the necessity of a bypass option; I should have run through the menu. I also should know by now that Elecraft leaves no stone unturned! I will try really hard to avoid making anymore dumb ASSumptions.Now that the ATU is bypassed, I'll start testing all over again and see how I fare. 73, Stan WB2LQF __ 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] Field Day experience with K3
A battery booster doesn't do much good very long if you're drawing more current from the battery than your solar cell is putting into it like WO1S was. A dead battery just gets deader quicker.

Re: [Elecraft] Field Day experience with K3
Or if the connections to the battery are not tight - and that is what I suspect based on the symptoms.. If the voltage was dropping below 11 volts, it would indicate either a high resistance connection to the battery or a defective battery. The Ten-Tec may have kept on operating, but that is not necessarily a benefit if it created a high IMD situation. 100 watts on a battery supply will not last forever - our FD solar charged battery operation lasted only 1 hour at the 100 watt level. 73, Don W3FPR.
