[Elecraft] [K3]: APF or Dual PB? You can have both!
Like some others have reported, I often tapped the DUAL PB button instead of holding it, thereby selecting the SSB filter instead of engaging the APF... To avoid this, I chose to assign the APF to setup II of the HICUT/WIDTH button, so an unintentional tap would only switch between HICUT and WIDTH... which is not so annoying. Then changing CONFIG:DUAL PB to NOR again, setup II kept the APF and now, switching between I and II, I can choose between APF and DUAL PB without going through the CONFIG procedure. I find this very convenient indeed. 73 es HNY to all Richard - HB9ANM - Richard - HB9ANM -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-APF-or-Dual-PB-You-can-have-both-tp5874347p5874347.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
[Elecraft] K2: 40 meter bandpass filter alignment: Best in RX or TX?
I'm doing a thorough realignment of my K2. I've done a RX-only alignment of the 40 meter bandpass filters by listening to a signal generator source while peaking L1 and L2. Could I gain accuracy here by using a DMM to monitor the AC voltage at the speaker output, peaking L1/L2 for max AC on the DMM? This is the method suggested (I believe in the K2 manual) for more sensitivity/accuracy when peaking L34 in an earlier stage of alignment. In a later stage, I tune L1 and L2 when in Tune mode, for max power output according to the K2's LCD. Which is the most accurate method -- monitoring with DMM in RX mode, or monitoring power output in TX mode? Or are they so close it just doesn't matter?

There is a carrier (birdie?) on that frequency and when I tap on the top of the radio, the tapping is clearly audible in the speaker. Has anyone else noticed this ? I don't remember the exactly frequency, but I believe I have a reverse-tuned birdie about this frequency on my K2. I say reverse-tuned because when you bump the dial, it moves in frequency more than the dial is bumped. It's not terribly strong, so I ignore it. It is likely the result of mixing products within the K2, which doesn't surprise me if you find it to be microphonic.

Re: [Elecraft] K2: 40 meter bandpass filter alignment: Best in RX or TX?
Andrew, During the initial build, it is important to peak the bandpass filters using receive to be certain they are aligned in the correct bands - this is especially important on the higher bands. After doing that, the bandpass filters are peaked using transmit where the peak is more easily observed. If your K2 is working and you are simply doing a re-alignment, you may skip the receive alignment and just do the TX alignment. For observing the L34 peak, I use Spectrogram (or whatever FFT application you will be using for the IF filter.BFO alignment). Use a filter about 700 Hz wide, and tune the 7000 kHz birdie for the greatest amplitude on the screen (at your chosen sidetone pitch) - the peak is quite broad, but look on the right of the Spectrogram display (the higher frequency content) and adjust around this broad peak point to get the higher frequency noise to its minimum. That will give you the best signal to noise ratio - which is the correct setting for L34. A DMM on the K2 output cannot show you all that, but if you have no other tools, it is one way to set L34. That being said, it is best to align L34 after doing the IF filter alignment so you can use the properly aligned filter during that step. While you are building the K2 and doing the preliminary alignments as you build, things are a little bit different than when building - you will do a better job if you do the final alignment with the completed K2, and the L34 alignment as I described is one example. 73, Don W3FPR On 12/29/2010 8:55 AM, Andrew Moore wrote: I'm doing a thorough realignment of my K2.

Re: [Elecraft] Reason to NOT buy a K3?
Hi Gary, You've already had a lot of great replies... Thought I'd throw my two cents worth in at this late date: The second RX is well worth having particularly for the low bands where you're more likely to be using a separate RX antenna. Too, if you're gonna be DX, it's VERY useful for listening to behavior on your TX frequency, as well as the pile up. Diversity RX is very useful at times, but if you don't have the antenna(s), it is kinda expensive to have just to say you have one... I'd probably second the 500hz and 200hz options, not a big cost savings, but it could be put towards the second receiver... One can argue the performance difference between 5 pole and 8 pole, I've not seen a meaningful difference in my contesting activities. For digital (RTTY), I'd suggest going with FSK and the aforementioned filters would be just fine. The K3 is as competitive as you are... I think it is very functional, provides easy and competitive performance at a good price AND has a tremendous team behind it. Firmware is always being improved or having features added, which is more than you can say for some other companies. IF, you ever need to work on/repair one, it is fairly easy to do and parts aren't unobtainium. One can argue about a radio's competitive advantage forever, there are so many things that go into winning beyond the radio. That being said, either the K3 or K2 are great contest radios IMHO. The K3 offers a lot of flexibility and growth options. Combined with KYBITC, decent antennas, decent QTH and decent propagation, you definitely will in great shape for the top 10 ;o) Cheers and see ya in the fray! 73 and Happy New Year to all, Julius - Julius Fazekas N2WN Tennessee Contest Group http://www.k4ro.net/tcg/index.html Tennessee QSO Party http://www.tnqp.org/ Elecraft K2#4455 Elecraft K3/100 #366 Elecraft K3/100 #1875 -- View this message in context: http://elecraft.365791.n2.nabble.com/Reason-to-NOT-buy-a-K3-tp5868025p5874614.html Sent from the [K3] 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

[Elecraft] K3/K144XV queries...
1. Even when NOT on 2 meters (K144XV off) my K3/100 seems to run hotter than prior to installation, e.g. the fans run more frequently. Is this general experience? ...and is it simply due to the changes in airflow due to the presence of the K144XV structure? 2. My K144XV puts out the quoted 10 watts. This seems to be its saturation value, as increasing the drive from 1 mW to 1.5 mW does nothing to increase the output. This is within specs, however, 10 watts is not quite enough to drive my TE 1452G amp to full output (I get about 200 measured watts out at this drive level). An obvious solution is to put another (!) amp between the K3 and the TE as a post-preamp so to speak. This seems downright draconian. Dave Anderson has suggested tweaking up the TE unit. Is there another way? ...as in slight mods to the K144XV?

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Hi Doug, The K144XV here had an +850 Hz offset when received. There is about 25Hz of temperature drift as well. Combined, the 875 Hz could be canceled using the offset setting. 12.5 KHz seems excessive, and that's the highest I've heard of. Note: My K144XV is one of the first ones produced (early 2010), and has remained stable (as above) during the last year. Hope this helps. Doesn't sound like it will. 73 and HNY! matt W6NIA On Wed, 29 Dec 2010 08:22:37 -0800 (PST), you wrote: Seasons Greetings, Just finished building my Xmas present (XV144).

Re: [Elecraft] K3 mod history?
Keeping a DCM-style record of each K3 would be virtually impossible. Factory-installed K3 options could be tracked by the original buyer/owner/builder but not by serial number, since many owners have multiple radios. More to the point, options are also bought/sold/traded in and out of K3's. The best example of this is filters, but it applies equally to major subassemblies like the KXV3/A or K144XV, etc. I had a brief discussion with Eric about this in October. When a K3 (or K2, etc.) arrives back at the shop, the service person inventories its installed options. But there isn't much more than a rev check of the option module(s) since many have multiple revs. The number of fielded radios probably far exceeds the number Elecraft staff see for service or new installs in the shop, and there's no way to know what options each K3 has installed from afar. Unless Elecraft has developed some unique form of TelePresence. :) The P3 works best with the IF gain mod installed. You can find mods at www.elecraft.com, click on K3 Mods + App Notes. It's the second mod shown from the top of the table. The mod is a simple resistor change that is easily performed in the field, and parts are available gratis (plus postage, I think). I've done all my own mods, and few are challenging for a moderately skilled kit builder. Mods aren't for everyone however, and YMMV. A few require patience and studying the problem before jumping in, but they are carefully crafted for ease and accessibility, and documented extensively (mit photos yet!), and fairly easy to perform. 73, matt W6NIA K3 #24, P3 #12 TDY Tucson, AZ.

Re: [Elecraft] Is there a way to connect K3 to CIV bus?
I think some of the microHAM units might do this. My MK2R+ advertises this capability. It depends on the purpose for connecting the K3 to CI-V bus. If the user is trying to control an Icom compatible peripheral from the K3, many of the microHAM interfaces (including DigiKeyer II, microKEYER II, MK2R+ and Station Master) provide CI-V compatible outputs. Information on those auxiliary or amplifier control outputs (including configuration data) are available in the User Manual. Note the microHAM interface generates an Icom CI-V transceive compatible data stream TO the accessory. There is no reverse path and as such one can not connect an Icom transceiver to the auxiliary CI-V jack and slave the K3 (or other supported transceiver) to the Icom transceiver. 73, ...

Re: [Elecraft] TCXO - 0.5PPM
Jim, Since you say you have hearing loss, that can prove difficult - I would suggest a visual aid. You might try using Spectrogram (or another FFT audio spectrum analyzer) when attempting Method 2. You should see the spike from the sidetone and the spike from the WWV carrier on the display, Once you get close to the correct point, you might be better able to hear the wow-wow-wow - adjust the AF gain to bring the ampliude of both signals nearly the same, and you should hear it. Go for the hearing aids too - they will make life more pleasant and enjoyable. I hear if you served in any branch of the US military for more than 6 months, you can get them free through the VA - worth checking out. I will be investigating that when I need new ones. 73, Don W3FPR On 12/29/2010 1:12 PM, radioshoppe wrote: Knut, Thank you for your suggestion.

Do you have an RTTY program that has a crossed-ellipse display (affectionately called crossed bananas by RTTY nuts)? If so, that might get you closer than 20 Hz by using your sight instead of your hearing. A steady Mark tone should appear as a single oval that is perfectly vertical or perfectly horizontal. You tune your rig by the amount of the mark tone that you have set -- if you can set the mark tone to some nice tone, like 2000 Hz instead of 2125 Hz, you won't have to do much mental gymnastics to figure out the proper VFO offset. Not all software have a narrow cross ellipse display, so you may need to find one that is satisfactory. Basically, with the standard RTTY shift, the cross-ellipse will go through 90 degrees of rotation with 170 Hz worth of offset. If you can find software which you can change the FSK shift, you can get even more accurate readouts. For example, setting the shift (i.e., the difference between the Mark and Space tone) to 50 Hz will move the peak of the oval by 90 degrees with just a 50 Hz VFO offset. I just tried WWV in cocoaModem's wideband RTTY display (whose oval is narrower than for other RTTY modes in cocoaModem). By using an FSK Shift of 10 Hz, I can easily eyeball a 1 Hz change. If your RTTY software does not allow such a narrow shift, it might have MSK (Minimal Shift Keyed) mode, where the shift is 22.5 Hz. (Note: MSK, not MFSK; they are different animals.) If you are using WWV, be sure to use a narrow filter so the modulations don't come through, or wait for the sidetones and subcarriers to stop. Else you will get an oval that shakes around :-). Alternately, you can look for iPhone apps for tuning musical instruments. Set your VFO offset for middle C or something :-). 73 Chen, W7AY __ 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

David... Thanks for the comment. I was unaware of this. There is a (barely) detectable warmth to the side panel of my K3 with the rig set on a band other than 2 (the rest of it, excepting the front panel, is cool), so you could well be right. I had hoped that one of the Elecraft Elves would comment on both of my queries. With regard to the power issue, I should have asked Santa for the external xvtr with its higher output. I have found (by measuring) that the TE 1452G is slightly peaked at the FM end of the band, though what one would want with 350 watts in Repeaterville I have no idea.

Re: [Elecraft] TCXO - 0.5PPM
Hello again, While I don't disagree with other people's suggestions that visual aids would be of assistance I am still a little bit at a loss (no pun intended) why your hearing loss should be a serious obstacle to detecting the zero beat on the side tone. Do you have any problem hearing your chosen side tone at all? In CW mode turn the AF volume down to 0 and press Spot to hear the side tone. If you can't hear the side tone, you need to adjust its frequency and/or amplitude until you can hear it clearly (hold Pitch to adjust frequency, hold Mon to adjust volume). Now is the time to turn the AF gain back up until you can hear stuff roughly equally as loud as the side tone. The flutter or warble in the side tone generally can't be heard easily unless you are within 20Hz or so of the desired frequency, so maybe that's your problem. I can send you a recording of what WWV sounds like with say a 10, 3 and nominally 0 error if you think it might help. Tried this just now and the fast flutter at 20Hz frequency error is clearly audible. AB2TC - Knut radioshoppe wrote: Knut, Thank you for your suggestion.

Re: [Elecraft] spectrogram
John: There are several(!) versions of Spectrogram available.

You CAN use newer versions of Spectrogram with my alignment docs, but there's absolutely NO benefit in doing so and newer versions offer features you will not need nor wish to use. Visit: For the K2 - http://www.n0ss.net/index_k2.html Spectrogram and docs are located about 3/4 of the way down the page For the K1 - http://www.n0ss.net/index_k1.html Spectrogram and docs are located about 2/3 of the way down the page The ONLY additional device you'll need is an audio jumper cable from the radio;s speaker output to the input of the sound card on your PC. Suggest using stereo connectors, but with TIP and SLEEVE (no RING) connected.

David - An additional point to Don's answer, You should ALWAYS match the MASS (1/32 - 1/4 typical in increments of 1/64) and PROFILE (screwdriver, single flat, conical, flat conical, etc.) of the Soldering Handpiece Tip to the work being performed. This is true for irons, desoldering/suction handpieces, as well as tweezers. TEMPERATURE is the third variable in the Soldering Triad. The most common mistake I have seen, is that novice and beginners will turn up the heat on the adjustable temperature soldering stations. That is often the worst step they could take -- damaging the underlying board. and component. Greg w9gb === David, Assuming a 2 lead component -- I would use 750 to 800 deg F to remove the component - heat each end alternately until it moves and then flick it away from its solder pads. When installing the new component, 650 to 700 deg F should be adequate, but that depends on the solder - if you are using lead-free solder, you will have to increase those temperatures. The soldering of any one connection should be complete in 2 to 3 seconds, if it takes longer than that, the soldering temperature is too low, but if it takes less than 2 seconds for the solder to flow, the iron is too hot. 73, Don W3FPR On 12/28/2010 9:13 PM, David Christ wrote: I have to replace a surface mount RFC on my K3.

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Doug Check the frequency stamped on the crystal, mine was the wrong frequency and gave the exact same problem, I requested a new one and it was also the wrong frequency. In the end I obtained a high stability crystal locally and it came up exactly on frequency. I don't know if Elecraft was aware of this but at the time it was very frustrating.

[Elecraft] K3: KAT3 Antenna Tuner Question
Hi Guys, I have a couple of questions about the KAT3 antenna tuner I'd appreciate your help with: 1) Where can I find detailed instructions for using the KAT3? Such as, step by step instructions on how to use the manual tuning option. 2) I'm tuning an Inverted L antenna and the initial SWR is higher than maximum SWR LED level as all lights are lit. (so I have no idea what the actual SWR is) Is there a way to get an actual SWR or Reflected Power reading via the KAT3? Yes, I know I should be using an Antenna Analyzer but mine is in for repair.

Re: [Elecraft] K3: KAT3 Antenna Tuner Question
Didk, you must have something terribly wrong to get this indication, like connected to the wrong connector or an open coax. I don't remember ever encountering a situation where my KAT-3 could not find a match. I have never tried a manual tune in the three years that I have owned the K3. Try connecting the K3 to your dummy load and see it it will tune. If you have a different tuner, try it on your L and see if it will work.

Re: [Elecraft] K144XV (was [K3] XV144 fault (offset problem?))
David, Mine drifts a bit when I first go to the band, but to solve that I just give it a key down into a dummy load for about ten seconds to warm it up, because When your not on the 2m band it is not powered. Someone correct me if I'm wrong, but I think that is what the manual says. That seems to settle it down quite a bit. However, I do wish it was a bit more stable. Perhaps they are working on a solution that will keep the xtals warmed up when you are on another band. That would be nice. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Member 35102 ARRL Life Member Retired Professional C# Software developer On Wed, 29 Dec 2010 19:28:10 +, David Pratt da...@g4dmp.fsnet.co.uk wrote: Matt - Interested to know that your K144XV is stable.

[Elecraft] K3: KAT3 Antenna Tuner Question- Update
Hi Willis, Thanks for the reply. I always leave something out! The KAT3 tuner will tune the Sloper fine. But when the tuner is out-of-line the Sloper SWR pins the SWR meter (lights all of the bars) and therefore I can't tell whether the antenna is too long or too short becuz wherever I qsy on the band the SWR still pins the meter. I was hoping there was a way to get an actual SWR reading from the K3/KAT3, such as: 5 to1. That way, I could check the SWR on the CW and SSB portions of the band and know whether the antenna needs to be shortened or lengthened. It appears that the K3/KAT3 will readout inductance or capacitance but not the actual SWR nor will it readout the Reflected Power. Since the SWR is over 3.5 to 1 the SWR bar graph is of no value for tuning the antenna. Guess I'll have to wait until my Antenna Analyzer is repaired.
