There are signals in the K3 ACC connector that can be used if you want to be creative, but without that, the K3 can be connected to the transverters like a non-Elecraft transceiver. Then what is the point of the K3 transverter interface? Does it simply provide a low level output? By the way (and very important) the signals from the K2 to the transverter are *NOT* RS-232. Look at the connector label on the K2 - it says AUX I/O. Just because it is a DE-9 connector and does contain 2 signal lines (TXD and RXD) that can connect to a computer serial port does not make it an RS-232 connector - the signals that go to the transverter are unique K2 internal signals. I fully understand this Don. That is the reason I stated serial and not RS232. Perhaps I could have been more pedantic :-) 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC DX Cluster Member RSGB, GQRP K2 #4044 |K3 #? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Firmware Updater under Linux / Wine
Hi Dick, I very strongly suggest that you use GetDefaultCommConfig whenever it is available. There is no guarantee that installing a driver updates the registry entries that you reference. Using the API ensures you're OK with future versions of Windows and oddly enough Wine.

Re: [Elecraft] K3 Receiver Performance
Chris, I don't have a tx antenna for top band but my doublet was piling 'em in on receive; it was an opportunity therefore to give the K3 receiver a good test and your signal, being fairly local and a K3 was interesting to listen to. I was particularly interested in key clicks. I noticed recently that the K3 cw waveform had a very sharp trailing edge and was told that this had crept in after a 'very recent' firmware upgrade and will be fixed. I knew you were there +/- 250 Hz (with the filtering down to 50Hz/250Hz 8 pole roofing filter) but by 'ticks' rather than clicks and you were LOUD; generally the signal sounded excellent here. Presume you were using an amp and I seem to recall you may have an Acom 1000 which seems very good with respect to relay timings (better be - I have one :-) so perhaps the residual ticks *are* down to the K3 trailing edge which hopefully will be sorted soon. I agree with you about the filtering. I could search out a weak signal within about 250 to 500 Hz of a booming eu and wind down the filtering and could copy the weak signal with no sign of spurii or breakthrough (assuming no key clicks...!). I'm not so sure about the 'dual pass band' filtering; I assume this uses the wide (2.7 KHz) roofing filter in order to accomodate the wide skirts and often when I switched it in the wanted signal would suffer from agc pumping from adjacent inaudible stations.This fitted with the way the S-meter reacted and disappeared when the 'normal' narrow filtering was reinstated. One thing did surprise me and that was the AFX. Set to binaural and the filtering out wide I was surprised to find that loud slightly off freq signals would appear to drop in strength in the headphones when I switched in the AFX. This was quite unexpected and very marked and had the effect of bringing up the wanted signal; I can't see a physical reason for this to happen so maybe it's 'all in the mind' but nonetheless very effective. It seemed like the unwanted signals were being sent to the 'back of the hall' when you switched in the AFX and keeping the wanted sigs right in the front row. I've had my K3 a few weeks now and I'm still being surprised about it's performance and features; the more you become familiar with it, the better it gets.

Ergonomics are excellent, all the necessary controls are well placed and what's more, work! I spent sometime in CQWW 160 CW this weekend, not a competitive entry with 406 Qs, 27 States and 50 countries but enough to assess the K3 rx. The general sound has already been compared to the Drake R4B sound. Yes. Very comfortable to listen to. The AGC constants are perfect, at least for me. The Width control coupled with Shift gives a very flexible selectivity selection and the Noise Reduction really eases help my power line noise problem. This morning around sunrise when the band peaked it was great to hear the W5s booming in, it was fantastic to be called during a run of Europeans by W6XI in Arizona, but the crunch came in the last hour or so at W2,3,4,8 sunset. The band was packed full of Eu, ranging from s7 to 40+over 9, and yet when I screw the width right down I can copy and work Stateside. Now, these condx are very similar to say 40m in CQWW CW and the K3 came through without a hitch. This is real radio, real contesting with a real contester's K3. Thanks Aptos !!

Re: [Elecraft] Transverting - DB15 UK supplier?
Bob, Also, bear in mind that some cables that are billed as VGA monitor cables actually only use 13 pins, not all 15. In fact, they have Pin 9 missing, which is one of the pins used for the Band Data Output signals. One of the pins in the third row (i.e., 11 to 15) is also missing. So be sure that you get a cable that actually has all 15 pins in the jack.

RE: [Elecraft] Transverting - DB15 UK supplier? - A Connector Caution
When fitting the connectors to the K3, make sure it seats solidly when the jackscrews are tightened. Fellows have reported that some *commercially-made* connectors have jackscrews that are too long. They bottom out in the nuts before the connector pins are fully mated resulting in intermittent connections! It has not happened often enough to identify particular makes or sources, as far as I know. I'm aware of two instances that have been reported, both from fellows using commercially made connectors. The problem is pretty easy to spot. The connector should be tight and solid against the rig after the screws are tightened. Those that do not fit properly allow the connector shell to wiggle around even though the screws won't go in any further. At least one fellow creates some small washers from wire and wrapped them under the thumbscrew heads so the screws wouldn't extend quite so far in to the nuts on the mating connector. That fixed it for him. I understand one other succeeded by removing the lock washers under the jackscrew nuts on the back of his K3. The connectors supplied by Elecraft for the Aux Bus cables used in the transverters and K2 are fine, *IF* the jackscrews are installed correctly! Of course, those fit the RS232 connector on the K3, not the ACC connector. It's easy to put the jackscrews between the wrong two stops inside the connector shell resulting in the same problem: too much screw sticks out and it bottoms in the nut before the connectors are fully mated. If you have one of those that seems loose, there's a picture in the XV transverter Owner's Manual showing exactly how the jackscrews should be installed (figure 6 on page 10). That manual is available on-line from the Elecraft Manuals and Downloads page or here: http://www.elecraft.com/manual/XV%20Transverter%20Owner's%20Manual-D.pdf Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

There were comments made about the seating of the connectors and threading issues.

If they bind up within a turn or two the chance exists that they are not the same threads. Not having a K3 I can't check what one it has but it is an American company.

At 5 W requested, I now get 5 w on 20, 30, and 40 meters, and about 4-4.5 on 15. A 7 watts requested (the maximum on the menu), I get approximately 7 on all bands but 15, where I get 6W. Is this normal for a K1, or should I do some tweaking somewhere (where?).

Not sure if I understand SSB filter settings. I have the standard 2.7KHz flter roofing filter so I assumed the max bandwidth on the Width control would be 2.7KHz but I find it goes up 6KHz. Since I am never likely to use that kind of width, is it not possible to set the DSP to have a max bandwidth coinciding to the to 2.7KHz filter?

Re: [Elecraft] Remotely controlling a K2
I can get you half way there. I've written a fairly full featured K2 control app for Mac OS X that will control the K2 over a network. I've been using iChat for the audio. I haven't tried Skype. I enjoy lying in bed and working CW using my Macbook. The K2 is downstairs being controlled by an iMac. Works like a charm. I haven't tried this, but it's written in REALBasic, which is cross platform, so I should be able to compile it for Windows and it should work. I would probably have to do some tweaking to get the UI to look right, but it should work. I'm presently knee deep in getting the K3 Utility for Linux ready to go, but if you can give me a few weeks, I'll see what I can come up with. This has been on my to-do list for some time now.

Re: [Elecraft] K1 power output question
I will echo what was already mentioned. Your measurements are about the same as what I get on my K1. 15 meters has always been a bit lower than the other bands. One other thing I have noticed is that the power readout on the K1 is not linear across the bands. I checked mine with a fairly accurate QRP wattmeter. If you align the power meter on the K1 so that it accurately measures 5 watts on 40 meters, it will read a little high on 15 meters and visa-versa. I set mine to be spot-on at 20 meters and it is close enough now on all the bands. Have fun!

Re: [Elecraft] K3 filter performance
All this leaves me wondering: What will be the best filter configuration (both TX and RX) for running FSK441 on meteor scatter? In case you're unfamiliar: FSK441 uses four-tone frequency shift keying at 441 baud. The frequencies of the audio tones are 882, 1323, 1764, and 2205 Hz. Each encoded character uses three tone intervals and therefore requires 3/441 seconds (approximately 2.3 ms) for transmission. FSK441 accommodates an alphabet of 43 characters. -- from the WSJT manual by Joe Taylor, K1JT Bill W5WVO Don Wilhelm wrote: Larry, You are quite correct that all filters are not created equal. For digital modes, the group delay is just as important (if not more important) than a flat passband and steep filter skirts. In fact, those filters with steep skirts often sacrifice group delay to achieve the steep skirts - but I am generalizing here, and that may not be a universal truth. Unfortunately, group delay plots are not common for filters since steep skirts seem to be the 'criteria of choice' for most amateurs. A Gaussian to 6 dB filter has a nice rounded nose and gentle skirts, but has a great group delay characteristic, OTOH, Cohn filters usually have great skirts and poor group delay in the passband. Group delay will make a difference in the ability to decode digital signals. 73, Don W3FPR Larry Molitor wrote: --- Joe Subich, W4TV [EMAIL PROTECTED] wrote: For a died in the wool RTTY DXer, a steep sided 270 - 300 Hz filter would be nice instead of 370 Hz from the 250 Hz filter. Over the years I've spent a lot of time looking at this issue. My interest is primarily digging weak RTTY DX out of the noise but I do occasionally get into a contest. I've played with a lot of radios and filters but most of my real testing was done with a FT-980, a TS-2000, and a FT-2000. While I have seen good weak signal performance with a 250 Hz filter, it was the exception not the rule. As an example, the improvement on the FT-980 going from the stock SSB filter to the dual CW filter was dramatic. But going to the 250 Hz CW filter lost about 6 dB in ability to properly decode weak RTTY signals. It was even worse on signals that had polar flutter. I no longer have the plots of these FT-980 filters but as I recall, the 250 Hz filter was a bit peaky in the middle and had poor group delay characteristics extending well in from the corners. As you say Joe, the determining factor is the passband ripple/group delay. In a typical bandpass filter the group delay goes to heck at the corners. But the shape of the corners varies from filter to filter. I've run a number of ham filters on a network analyzer and plotted group delay. Seems like no two filters are the same even if the same part number. This I believe is due to ham filters being so cheap and manufacturing process control being minimal to keep the sell price down to what we can afford. So I would say, if you have a 250 Hz filter, no matter where it's placed in any radio, give it a try on very weak signals. Switch between a wider filter and the narrow filter and see if there is any degradation. If not, use the narrow filter. Other wise, plan on not using any filter less than 300 Hz in passband width (note - this is NOT the 6 dB down width!!! very important!!) if you want optimum weak signal performance. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 filter performance
Since I have gone through the optimization of four different radios for WSJT use, I can make some suggestions. As it turns out the same requirements apply to the JT65 modes used for EME so you only need to have one setup for any WSJT mode used for any propagation mode. FSK441, JT65 A,B C, and the new JT4 modes all require a 2.7 kHz or greater bandwidth for optimum performance both on TX and RX. Although the software can compensate to some degree for passband amplitude variations, the best performance will be obtained with a perfectly flat passband for both TX and RX. Even though the bandwidth of these modes is less than the 2.7 kHz specified, you need to have the wide filters to allow for doppler, radio drift, frequency errors, etc. There is no downside to using the widest filter possible for these modes as the detection bandwidth inside the software is on the order of 1hZ! Many EME operators use a SDR radio wide open at 96 or 192 kHz width and the beta software which will decode multiple signals simultaneously in that passband.

RE: [Elecraft] Remotely controlling a K2
I run VNC with no real problems. The secret is to only allow that port access to specific IP addresses.

[Elecraft] Power 160M
Hi all I Noticed that during the cq 160m contest this weekend that I could not get more than 4 watts out of my K2 The Requested power goes up to 15.2 of course but I cannot get more than 4 and on the first transmit I get a momentary Hi current. My power supply is steady on voltage and current. I switched the display on the K2 to display V/I and the voltage drops on transmit and the current goes up to about 2.4. This is within the Cal Current range. Now on 40 meters it is fine it puts out 14 watts. same with 30m. I haven't tried the other bands. Also the Requested power on 160m does not match at any request of power through out the range from lowest to highest. Is this connected?

Re: [Elecraft] K1 #2500 QRV... almost...
Thanks All that helped out ... I appreciate the assist! I heard back from Tech support and they agreed that it is probably a bad 20M crystal, so they are sending me a new one. After hearing that from them I wondered what would happen if I replaced the 20M with the unused 17M crystal, so I swapped em out and it now works on all 4 bands so it WAS the problem. So now I just have to wait for the new Crystal and then I can finish off the kit. I am one happy camper... This calls for a nice glass ( or 2) of some of Merlot I hope this will help others in the future that may have the same experience. 73's Rich, AB6TY Paso Robles, CA K1 # 2500 -- So far I have been able to get 40, 30 and 15 working ok but I do not hear any signals on 20M. I went through all of the test points of the Cheap Dirty Signal Tracing list. all points seemed to work except points 4, 5, 6 on the list, *4) *Filt Board, junction C11/C12, output of Band 1 RF BPF. *5)* Filt Board, C13, inter-stage coupling RF BPF. *6)* Filt Board, junction C14/C15, input to Band1 RF BPF. I was able to hear a jump in signal noise on all of the other points. So I guess there is a problem in the Pre-Mixer area for 20M. I went through and removed any excess solder and reheated each joint for all of the components. and I removed the Xtal to make sure there was not a solder to ground problem under the can and then resoldered the xtal back on the PCB. I was able to hear signals on 15M , and had QSO's on 30 40. Could it be a bad Xtal , relay switch. or C3 or C4 variable Caps??? Rich, AB6TY Rich Smith wrote: Well.

Your measurements are about the same as what I get on my K1. 15 meters has always been a bit lower than the other bands. One other thing I have noticed is that the power readout on the K1 is not linear across the bands. I checked mine with a fairly accurate QRP wattmeter. If you align the power meter on the K1 so that it accurately measures 5 watts on 40 meters, it will read a little high on 15 meters and visa-versa.

[Elecraft] K3 #272 QRV in style
Having used all my stored patience getting the K3 built and receiving on Sunday, the KPA3 100 watts was the next order of the evening for tonight. It went enjoyably as usual, but all the PA connectors take quite a bit of physical force and you really need to support the RF board carefully to keep it from an over flex condition. Press -real- hard, support the board from the bottom, and don't zap it with static while doing it. ;-) I pressed from the bottom with a folded up anti static bag under my fingers. I put the K3 on a 40 meter dipole at 30 feet, used 75 watts, and put out call number one (ever), and hooked up with K2A/KH6 at 7.054. Max gave me a 599 from Hawaii. This radio is just a pleasure to the senses, sounds great, feels great, the pictures don't do it justice. I'd suggest that by the book is the only way to go with this transceiver, -everything- has been thought of, but you really need to follow the plan to the letter. For example, the front panel has 4 main standoffs, all 5/16ths long but 2 are drilled at 2-56 and 2 are 4-40. I can't see the difference between those sizes myself but you need to take the time to know that there are 4 in the process, compare them against each other, then mount them where they go - specifically. All round head screws go on the bottom, flat head on the top - all teeny tiny and look remarkably the same to me. Building RC helicopters put your head in the right frame of mind for getting all this tiny work just right. There are lots of parts that should not be forced and many screws that should not be over torqued. I'd suggest to most anyone that does not have real good finger tip skills, fairly sharp eyesight and a good selection of miniature tools - to just to buy the factory assembled unit. The radio itself is THAT good. Having it built by the book by the people who created it is, IMHO, worth every cent they charge and it ought to be more. ;-) YMMV de wb8yqj ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re:[Elecraft] K3 filter performance
Larry Molitor wrote: The DSP filters and DSP modems following the IF filters cannot re-constitute the distorted signal so Do not, rather than cannot. Firstly, the Finite Impulse Response (FIR) filters used need not, and are almost certainly constructed so that they do not, introduce any group delay distortion of their own. That means that you can still use narrow DSP filters, even if you have to compromise the roofing filter. Moreover, it has been standard practice for at least a couple of decades, to use adaptive versions of such filters mitigate group delay distortion in telephone modems. In that context, they generally require synchonrous transmission, because the standard adaptive equalizers only fully cancel inter-symbol interference at the actual sampling points. Although synchronous operation does make the adaptive process easier, I'm not sure that the longer filters that can be implemented in modern fast DSPs, combined with the relatively fixed distortion the the receive filters, cannot compensate for non-synchronous signals. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
