[Elecraft] K3: Alarm Clock
Hello Elecrafters! Last night I turned on the alarm function in my K3 and turned off the rig. In the morning the rig was turned on, thats good. But lost the RS232 connection. Turned off than on the rig and all back to normal. Anybody noticed this? DXLab Suite and Elecraft K3 the best a HAM can get!

[Elecraft] K3 - KDVR3 FW request
Hi all, I've just finished participating in the UBA SSB contest as a 6h low-power entry using my K3/100 and the KDVR3 I installed last week. This setup was a joy to use and the KDVR3 certainly relieved the strain my vocal chords, hi. The only thing that bothered me a bit was that the KDVR3's playback loop cannot be overridden by PTT or VOX. Each time a station called I had to take one hand off my PC's keyboard to stop the playback. Not really a showstopper but a bit awkward nonetheless. I seem to remember a post stating that playback override by PTT/VOX is on the list of to-do items. I hope it makes it to the top of the list soon ;-). Anyway, I had a great time during the contest and my K3 amazes me more everyday. This is one heck of a radio! Thanks all at Elecraft! 73 Glenn ON4WIX / OR4W ___ 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 Dual Receive Surprise
One curious phenomenon I've noticed is comparing digital versus analog TV signals. My cable service uses the same channel on cable as the over the air VHF channel for the local broadcast TV stations. All signal en-, trans- and decoding will require at least one to two frames. At work the broadcast signals of the same program which leave our company will often have a delta of a second or so depending on what kind of processing was necessary (i.e. satellite broadcast, terrestrial broadcast, internet stream, etc.). Also any resynchronizing which may occur in the various system the signal is passed through also costs time. This is most likely what you are noticing. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Pumping with AGC
Gary: Guy, K2AV, said, Make sure in Config Menu you have AGC PLS nor. This is the probably the single best suggestion of all other than riding the RF gain. Most prevalent and especially during contests are key clicks - hard keying - which extend at times several kHz fore and aft of the carrier freq. If AGC PLS is set to OFF the key clicks will surely affect the AGC. In my opinion, the K3 handles this situation better than any other rig I've used - which is many. Again, make sure AGC PLS is nor. I have no troubles, even on the topband with preamp on, with AGC pumping and a 200 Hz filter. 73, Dan -- N3ND ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] IO Issues with K3
I've been finding the same problems in the 160 test. A lower baud rate seems like it would be fine for most things, but I wonder if it would tend to shorten any Morse elements? Now that I think of it, maybe not, since the speed would remain the same at the USB end of the interface. And to send CW, the program just toggles a handshaking line, independent of baud. I do think that CW seems a tiny bit clipped from N1MM compared with that using the built-in keyer. I'm thinking RF problems too. I just re-intsalled my quarter wave Marconi since the landscapers cut down my main antenna tree the other day, so I probably changed the local field strength in some way. N1MM is having other hesitation problems as well. I should probably re-install it. 73--Nick, WA5BDU Cady, Fred wrote: Check the baud rate.

They can hear the tones but if the tones are very close in frequency they cant tell one from the other other then sending speed and style. An interesting fact. in a room with 150 people being tested for SONAR which several pair of tones were played. Some tone pairs were the same frequency, other tone pairs were offset from each other. You had to mark weather the tones were same, second tone high, or second tone low. You had to get %85 right or you failed. When the test was completed there was only 10 of us that passed. For us that are not aflicted with this minor disablity using your brain as a filter for the pitch you want can make for good cw copy.

[Elecraft] K3 in 160 contest
Admittedly, current conditions on 160 are the best I've ever seen, but for us poor cousins in the center of the country to be able to work zone 14, 15 and 16 like 20M was truly fun to hear. The K3 really shines when you are trying to pull a European out of the hoard of East coast callers. MANY U.S. signals were 60 db over 9 here and the K3 was solid as a rock in pulling through DX. I generally stayed below 350 hz BW for most of the weekend. I like my 500 hz filter, but I may actually have talked myself into getting the 250 hz filter to fill my remaining slot. I found 70 countries (a couple may disappear since they were ESP), 56 states/provinces and 1130 QSOs. My sleep schedule was out of whack due to work travel prior to the contest, but got about 20-22 hours in and had a ball. Some day I'm actually going to be able to stay awake for sunrise openings. ;-) I heard several K3 owners that I recognize from this list and was glad to work you on the air again.

Re: [Elecraft] CW Tone
Tom, What you are missing is the ability to even conceive of the problem we tone-deaf folks have. Yes, we can hear the 'warble', and once detected it is easy to get the warble rate down very close to zero. The real problem for some of us is in getting the two tones close enough to produce that 'warble'.. I can hear two tones, and know that they are different, but my brain cannot determine if I should increase or decrease the frequency of the signal to get the two tones closer in pitch. For those who share my difficulty, tools such a Spectrogram and in the K3, the CWT indicator are valuable aids. 73, Don W3FPR Tom, N5GE wrote: What am I missing here?

If you have access to an RF Probe or oscilloscope, you can check for the presence of 4 MHz at U1 pins 15 and 16. Make certain there is continuity between the socket pins and the leads of U1.

Re: [Elecraft] Sub-receiver or 2 k3's
A few weeks ago on this reflector I mentioned that I was using my two K3s for diversity. I have two full station setups (primarily for RTTY contesting), and one is connected to 80/20/10 antennas and the other to a 40/15. Also, each separate station feeds a different side earpiece in my headphones, so it was very easy for me to implement diversity just by linking the VFOs together through N8LP's LP-Bridge program. Even though the other K3 is on the wrong band antenna, it all works FB. I have not tried to link the master oscillators in the K3s, but I did carefully tweak the freq calibration so they are on the same freq (within tenths of a Hz, I think). Since I already had the two radios here, it made sense for me to do diversity with them when the second radio was not busy, but maybe not so sensible to buy one solely for this. Go back through the archives and search for my posts both here and also the LP-Pan reflector. Jerry W4UK At 18:17 1/25/2009, N1IX wrote: I was going to install the sub-receiver in my K3.

[Elecraft] K3 and 6m
I don't know what the problem with others who think that the K3 is hard of hearing on 6m. I have not had any problems working DX with a 5ele yagi up only 24 feet this past summer. Some of the signals were weak but I had no problem picking them out of the noise. I was using the K3 internal pre-amp. I also had the Elecraft PR-6 pre-amp (beta version) and used that a few times. It did bring up the noise with the weaker signals but think the new PR-6 has a better s/n ratio. I have a few stns in RI who run KW's but do not seem to de-sensitize the K3 at all. It is rather difficult for a manufacturer to include the VHF/UHF bands on an all HF rig, unless they make a separate rx for these bands and that would definitely jack up the price of the rig. I think Elecraft did a great job in designing the K3 and their product support is just superb...something you would not get out of the other competitors. Just my $0.02 worth and hope I don't stir up a hornets nest on this posting. Tom/k1tl... ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 6 Meter performance.
Phil, Jim, others ... I've been using my K3 on 6M with good results. It hears well, even without a preamp in my quiet location. I did add a DEM preamp which, of course helped a bit, but -not- to the extent that I was able to hear anything I could not already hear with the basic K3. When they became available added the PR6 just to keep it in the family and it works well. I sold the DEM pre-amp to a local friend with a K3. 73!

[Elecraft] K3 S-Meter Calibration and SMTR MD abs
Just a quick question concerning the calibration of the K3 S-Meter and the use of configuration SMTR MD. I have calibrated the K3's S-Meter using the manual calibration procedure (K3 Preamp ON). Everything calibrates fine, but if I try to use configuration mode, SMTR MD abs as opposed to SMTR MD nor, the S-Meter does not show the calibrated results. It shows the S-Meter reading of the K3 when it is in a no attenuation, no preamp condition. This doesn't sound right to me. Shouldn't SMTR MD abs show the calibrated indication (even with the preamp off and the attenuator enabled)?

Re: [Elecraft] 6 Meters
I can't speak for the engineering or product decisions that went into offering 6 meters with the K3, but for an excellent low-noise 6 meter capability Elecraft does offer the XV50 transverter which is well integrated into the K3 and K2 rigs offering direct frequency readout, all of the capabilities of the base K3 (or K2), and the 6 meter band becomes part of the band selection just like the HF bands. The XV144, 222 and 432 round out the same capability, letting you cycle through bands using the K2 or K3 bandswitch from 160 through 70 cm with one rig, and each of the VHF/UHF transverters has a low-noise high-performance receive front end designed specifically for that band. As Wayne's often mentioned here, the advanced up-conversion design of the K3 is superior for HF but makes incorporating VHF a real challenge. Using an XV transverter specifically designed for each VHF band keeps the K3 (or K2) operating as a tunable I.F. in the HF (28 MHz) range.

Re: [Elecraft] Sub-receiver or 2 k3's
Back in the 1950's the ultimate Ham rig include a kilowatt amplifier for each band, often stacked in a cabinet on the desktop or in a rack alongside the desk (we still had to adjust our transmitters when we QSY'd in those days). Separate amps allowed one to optimize the circuits and have them pre-set for each band. Perhaps it's time to revisit that concept with a K3 for each band, or at least a K3 for each mode, so all the presets, tweaks and adjustments can be made in advance and one only need select which rig to use! Picture a stack of at least four K3's optimized for SSB, CW, Data, and FM or a stack of 11 of them to provide one per band. My fantasy doesn't quite reach to one per band and one per mode, but what a sight that would be...

Most commercial 6m radios have a front end noise figure around 6 dB and lack sensitivity on 6m in deference to better large signal handling capability. As I recall, the stock K3 is somewhere around 12 or 13 dB. You won't notice the lack of sensitivity when you have strong signals on 6m such as Es during June and July (or yesterday from the East Coast to Europe). However, if you live in a quiet location, you will DEFINITELY gain some critical dB sensitivity when you try to copy very weak signals at the noise level (or BELOW the audible noise level, if you use the weak signal digital mode of JT65A). With the addition of the PR6, you will have the hottest 6m receiver available anywhere in the world ;-) Enjoy your new piece of equipment!

Ron D'Eau Claire wrote: As Wayne's often mentioned here, the advanced up-conversion design of the K3 is superior for HF but makes incorporating VHF a real challenge. No challenge at all... had it been thought about at the design stage. Since the K3 is top-of-the-line in so many other respects, it rankles that the 6m sensitivity is poorer than that of many 'inferior' transceivers. Even my old IC746 has a built-in alternative preamp for 6m which makes it easily capable of hearing antenna noise, which my K3 cannot (and yes, it does meet the published sensitivity specification). Phil just discovered something very similar with his old FT100. I'm not shouting or getting angry, but do remain quietly insistent that the inferior 6m sensitivity is a blemish on the K3's otherwise excellent performance. With great respect, it doesn't matter whether 6m is a minority interest or not; this is about excellence and what's needed to achieve it. All the K3 does need for 6m is an alternative preamp with slightly more gain and a lower noise figure than the existing preamp (which was optimized mainly for strong signal handling). That's all it takes to shift the K3's window of dynamic range downward by several dB, which will make it capable of hearing antenna noise on 50MHz at a quiet site; which presently it isn't [1]. Although a preamp can improve the sensitivity by a few dB, the penalty is that a greater number of decibels must always be lost at the strong-signal end of the dynamic range. However, the K3 is better placed than any other transceiver to trade off a little of its dynamic range for a marked improvement in weak-signal performance. The PR6 and many alternative preamps have proved those points. But the point that many people are making is that an adequate 6m preamp did not *have* to be an external accessory. Much of the size and complexity of the PR6 is due to its being an external unit. With forethought, something similar but *much* smaller and simpler could have been designed as an integral part of the KXV3 assembly - there's plenty of space in there. A selectable internal preamp is still possible as a modification involving a few track cuts (watch this space). All the above can be expressed in more technical detail, in terms of antenna noise temperatures and signal/noise ratio on weak signals, but that's the Sunday evening version... oops, Monday morning. [1] if anyone can distinctly hear 6m antenna noise on a bare K3, yours is not a quiet site. If you can't hear antenna noise but still claim to be able to hear all the weak signals... are you sure you've heard them *all*? -- 73 from Ian GM3SEK Editor, 'The VHF/UHF DX Book' http://www.ifwtech.co.uk/g3sek ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 - RF Board part 2
At this point of construction, the 40 meter receiver should be as good as it gets - the following assembly only adds the other bands and the transmit section. You do have a problem somewhere that should be investigated. The easiest first step is to try the Quick and Dirty Signal Tracing technique that is in the Builder's Resource page at the Elecraft website. If that does not reveal the area of failure, then one can resort to the Receiver Signal Tracing steps in Appendix E of the manual. 73, Don W3FPR David J. Wallace wrote: Hello Elecraft(ers)!

Unfortunately, they didn't, and I could barely hear those remaining. We did a quick look around and found 14319 open. We then announced that and QSYed. I will look for a more elegant approach next week, including asking any non-Elecrafter if they would like to join us on 14316. I am new to the NCS thing. We will refine it as we go. Thank you for your patience. 73, Phil, NS7P -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net]on Behalf Of jferg...@aol.com Sent: Sunday, January 25, 2009 5:26 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Elecraft ssb net today I was able to pick up the beginning of the net at 1800z and got a light but workable signal here in Marathon, FL.

Re: [Elecraft] 6 Meters
Ian, Much forethought was put into this (at the design stage). We knew ahead of time that the 6-m MDS was going to be in the -135 dBm range with the internal preamp, due to the losses in the T-R switching and narrow band-pass filtering. Both were required for this design. A separate 6-m preamp would only have boosted 6-m MDS by a couple of dB because it follows the other front-end losses. Thus we elected -- from the start -- to provide for an *external* 6-m preamp, patched between RX ANT IN/OUT. With this solution, we get a world-class 6-m MDS in the -144 dBm range, and you don't pay for it unless you need it. Every rig has tradeoffs. This was one of ours. 73, Wayne N6KR Ian White GM3SEK wrote: As Wayne's often mentioned here, the advanced up-conversion design of the K3 is superior for HF but makes incorporating VHF a real challenge.

Re: [Elecraft] (Elecraft) 6mtrs!
Hi Jim, No worries on this. Yes I am blessed thank you and probably my K3 is as well if you knew the full story. The serial number of this one is # 791 and the one I used last summer on 6m was #850. I think anyone that knows me, including Wayne and Eric, would not classified me as a person that thinks Elecraft can do no wrong. Eric I am sure will tell you different. However they and their staff sure do a lot that is right. They do try their best to make it right with you if something is wrong! Jim, I trust me I wasn't judging you or others having a problem with 6m sensitivity from the front roll of the Elecraft Church. Without getting emotional I was making a statement as to maybe the cause. I was not implying that you or others don't have a problem. I am sure there is something going on, I wish we were closer so I could offer a hand in running down the problem. Here is the run down of my station that I don't usually give as it changes almost daily. During the month of June 2008 the shack consisted of serial # 850 K3, TS-480, IC-756 Pro 3, and a IC 7700. Again my antenna setup was a meager for 6m, just a 3 element mono-bander with almost no feedline going to it. At no time did I find the K3 lacking in sensitivity on 6m compared to the other rigs and yes I did switch them in and out. I did wonder why some other K3's seem to be deaf on 6m compared to TS-2000 or 746 Pro's as reported here on the reflector. At my station the result was not the same as some report here and so I kept the K3 on the 6m beam, while using the other rigs for HF. Later postings from Wayne explain things on the design of the K3 and then the new 6m pre-amp, so I quit wondering so much. Having said the above, I can also say the same thing in reverse. I chase a lot of weak signal work with wire only antennas and at no time is there a distinct advantage between the K3 and say the Pro 3 or even the 7700. All rigs have their pluses and minuses, plus I am pretty good at wheeling the knobs on the various rigs. I am not running a contest station here with mega power, multiple antennas, SO2R, etc. If I was running SO2R or similar setup I might be more biased towards the K3 and move up to the front pew of the church. I will say this, under strong RF conditions I have never seen a rig hold up better than the Elecrafts. The kind of RF levels most shacks will never have to deal with. This has nothing to do with 6 meters or your problem, but the above was to let you know I am far from being an Elecraft groupie. Not that being a groupie would be all that bad either. Jim I do wish you luck with your problem and I meant no offense in my posting to you or others on this list. 73 de jay/w5jay.. Jay, Maybe you're blessed or you don't think that Elecraft can do no wrong! What I and others are saying is that in OUR SITUATIONS the 6mtr. section sucks! That's why we're procuring the 6m.

[Elecraft] [K3] Main vs. Config Menus
I don't know about anyone else but I don't understand the K3 Main vs. Config menus. The Main menu is supposedly the menu of items that one would need to select the most often. Well for me, I almost never visit the main menu. I will visit the Config menu almost every day. It seems that my experience is just the opposite of what was planned for the menus. Maybe someone should take a statistical measure of the menu items most needed and place the top ten items in the Main menu. I would bet that the top ten items are not in the current Main Menu at all.

[Elecraft] Elecraft CW Net Report for January 25th, 2009
Good Evening, The band was quite happy today! So much so that I was having problems discerning separate signals ;) More than once I had to call again to attempt to get one character out of the howl. Stations checked in from Connecticut to Southern California and from Georgia to Oregon. Only a couple had QSB so then they too jumped up to at least S5. It was very nice after some of the problems we have been having with propagation lately. I took a flakey tuner out of the antenna path which made some improvement and did a little work on the higher of my two antennas. A good spring day will be required to do all the work necessary to unwrap the lower antenna from its trapped location amoungst the branches. A couple raising and lowering operations with some pulling in between will get it free but that means I will be up and down the ladder a lot. From the reports I heard winter is back; in force for some and in a pleasant way for others. The California stations spoke of rain. I know my southern neighbors would like to fill their reservoirs and water their lawns before summer returns. I would gladly send the clouds down there to get some sun now and then. There are times during the winter months when the sun is only a fond memory. Waysides east of Hood River, Oregon are filled with RVs of folks trying to find a day or two of sun in their vacation from between the Cascades and the Coast Range. However spring is only a month or so away if you follow the calendar of the hummingbirds. They start flitting in during the late part of February. Since there are not many flowers then they must survive on the tiny insects which hatch around that time. On to the list = On 14050 kHz at 2300z: NO8V - John - MI - K3 - 820 QNI #55!!!

The sun is definitely on its way back. During my morning sked I track when the sun pops up over the mountain on the clear or hazy days. There is one anomaly when it rises in a notch in the mountain but that is only for a day or two and then it is back to its normal progression until it clears the mountain entirely from daybreak until sunset. Soon we will read if the ground hog in Wisconsin foresees an early or a later spring for those in the Midwest. It is time to get in the last month or two of iceboating and ice fishing before the breakup. And then, in a matter of a day or two, the lakes will be clear and the sailboats will appear. At the ARES meeting last week I had a discussion with another operator about the fall colors so I am feeling a little homesick. Maybe one day I will move back home. Until next week I hope you stay warm and stay well, 73, Kevin.

[Elecraft] K3 temperature
Since I fitted the second receiver, my K3 is running a whole lot warmer, even on receive with the sub receiver turned off. In particular the front half of the right hand side panel is almost hot and the front right hand corner of the top cover is also very warm. Before the second receiver installation the PA and FP temperatures ran about the same, in the high 20's if I remember. Just now the FP temperature is nudging 44 degrees C and the PA is 36 C. This is after the rig has been on for several hours, receive only, although it quickly heats up to these temperatures when it is switched on. I am guessing that the air flow and thus the cooling ability of the rig has been significantly impaired by the KRX3 and this is causing the very high temperatures. I wonder if this has any long term reliability implications ? I also wonder if others are experiencing similar temperature issues with KRX3's installed as I do not recall seeing any postings on the subject.

Re: [Elecraft] [K3] Main vs. Config Menus
Mike, I thought about this some time ago but as I got used to the present arrangement subsequently forgot about it. I can never remember which items are in the MENU, which were in the CONFIG and which require TECH MD. Would it be possible to start out with everything in the CONFIG and have an option to move your personal choice of items, you regularly change while operating, to the MENU. By saving your settings you could even have different MENU items for SSB, for CW and for DATA. The appropriate settings could be loaded before a contest. The list of MENU items could be very small for fast access. Perhaps items could be sent to the MENU by MODE or even operation type (contest, DX chasing, 160M, 6M)? If its just a couple of items then the PF keys can be used but you have to set that up. I don't know whether many K3 owners would be interested in such a feature. How many times do you use MENU/CONFIG during normal operation? It seems that we never stop asking for changes to the firmware but a healthy discussion usually produces better ways of getting the most out of the K3 which may, or may not, require a firmware change.

Re: [Elecraft] K3 temperature
Since I fitted the second receiver, my K3 is running a whole lot warmer, even on receive with the sub receiver turned off. The aux DSP adds around 100 mA even when the sub receiver is turned off, as I recall, so some increase in temperature is normal. The KRX3 module itself adds nearly zero current when turned off, and I don't believe it could cause any increase in temperature since just due to its location above the RF board. When turned on, the KRX3 adds about 150-200 mA. All of the components are rated to handle much higher temperatures than you normally encounter (typically 70 C). However, I've never seen an FP temperature of higher than 41C, so if you're seeing 44C, you might check your FP temp calibration. Even 44C is very unlikely to be a problem. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] 6 Meters and TX IMD
Elecraft K3 is sold as a High Performance Radio, this is in print clearly stated on the web page. The 6m RX in K3 can not be called high performance. With a NF of above 10 and MDS as it is. The transmitter on SSB has so poor IMD that it can not be called high performance. ARRL and many others has measured poor TX IMD. I hear K3´s on the air every day with poor SSB TX IMD. People do have problems with PSK and other digital modes due to poor TX performance. IMO 6m is fixed with the preamp, no big issue anymore. However it should be stated in advertisement that for high performance on 6m K3 needs a preamp. Then we have the transmitter, what to do??

Re: [Elecraft] 6 Meters and TX IMD
Hi Jan, I don't think the K3/100's -29 dB for TX IMD is all that far out of line with today's 100 watt class rig. In fact most 100 watt 13.8 volt rigs are a dB or two from this. I think the K3 QRP rig wasn't this good on bands above 17m @ higher power, but still measured -27 dB. Although it would be nice to have it much better (mid 30s or even in the 40s), even my Icom 7700 is was only measured @ -28dB with MRF150 final with 48 volts on them. Seems very rare for a current rig to be in the high -30s and -40s. So I am not sure what the bench mark would be on TX IMD these days or if we could afford it? Question, can you hear IMD off the air or just the artifacts? As Wayne said earlier everything is a trade off. 73 de jay/w5jay.. - Original Message - From: Jan Erik Holm sm2...@telia.com Cc: elecraft@mailman.qth.net Sent: Sunday, January 25, 2009 11:53 PM Subject: [Elecraft] 6 Meters and TX IMD Elecraft K3 is sold as a High Performance Radio, this is in print clearly stated on the web page.

Today there is a great opening. Signals are screaming from the FT 100 and hardly heard on the K3 using an antenna switch. Guess I better get a Preamp in line quickly.

I did order the 6m. preamp because of that short-coming! But you would have thought that the BOYZ @ Elecraft would'nt have short-changed 6m sensitivity as ALL THE OTHER BANDS HEAR WELL!!! Why build a quality rig if one-band is only added as a after-thought??? Jim/nn6ee S/N 2406 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
