I did notice when I first got the K3 that the QSK/semi break in was light and I had to compensate for that in my keyer.

Just for general information I have just wired up my K3 to my FL7000 linear for auto band change as per the directions from W4TV back on 23 May. It works great but the tx inhibit is unusable in other than QSK.

Most good external keyers offer 'keying compensation' in msecs to offset this; my FT990 needed as much as 8ms extra on the characters to give a 1:1 dit ratio in qsk v semi break-in. Just done a quick 'scope check here using my Microham cw keyer and the results are 'inconclusive'. In qsk the space is actually slightly less if measured from the end of the fall to the start of the rise, but slightly more if the dit is measured across the 'top' ignoring the rise/fall time. I forgot to check using the internal keyer but this seems pretty good to me. Having said all that I see that I have configured my Winkeyer with 3ms 'keying compensation' which was done on the basis of it sounding a little choppy previously. 73, Stewart Rolfe, GW0ETF (K3 145) -- View this message in context: http://n2.nabble.com/K3-Keying-tp840393p840685.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Digital audio out ?
Hi Simon and Julian, thank you for your support. I'd also appreciate that if such a signal would come out of the K3. Others (IC-7700 et al.) support that too, sometimes via USB or ethernet. I'm not happy to digitalize the analog line out audio signal external into a PCM stream by using e.g. a microcontroller because of the additional signal propagation delay of the ADC conversion. For using the K3 as a remote TRX it is nowadays not state-of-the-art to let a PC run all days long. A modified wireless lan router is less expensive, regarding its power comsumption. I already thought about using a wireless lan router w/ integrated VoIP port (where you an plug in an analog telephone) to plug the line out and the line in port of the K3 to this device by using an telephone-interface to solve that problem. That could provide a audio connection e.g. via skype to the K3 from all places, if you want even by using a standard telephone line to call the K3 from every fixed line or cell phone.

Bluetooth is suitable if you use a Jabra A-210 Module for the audio transmission directly to a headset and a second Bluetooth dongle in combination w/ a serial to usb converter for the data to a PC / notebook computer.

But I there is a supplier for a Bluetooth modul which supports Class 1, I'm working on it. I do have access to a embedded system that comes with a ARM7 µController. I should be possible to run an embedded Linux at that device. It would have all necessary ports (2x RS-232, USB (the protocol is already implemented), Ethernet (the protocol is already implemented), native UART's). The size of that board is only 800 x 300 mm (31,5 x 11,8 inch.). The price is less than 100 €. That should fit into the K3 with no problem.

Re: [Elecraft] K2 RTTY
Logan, What you say is true and quite workable *except* for the times when there is a strong undesired signal inside the IF passband. That strong signal takes over the AGC and reduces the receive gain causing all signals (including your desired signal) to become weaker. The solution is to set up the RTTY set of filters so one can narrow the receive IF bandwidth when a strong undesired signal is present. I set the RTTY filter widths as follows: FL1 = OP1; FL2 = 1.00; FL3 = 0.70; and FL4 = 0.40. I use Spectrogram to center the narrow filters at 1000 Hz (you can simply copy the SSB FL1 BFO frequencies to the RTTY FL1 settings. In use, tune the desired signal using the K2 VFO to the vicinity of 1000 Hz (your narrow filter center) and enjoy the QSO. Should an undesired signal enter the passband, you may switch to a narrow filter to reduce the AGC pumping effect. A great advantage for using the RTTY filter set instead of the SSB filters for data modes is that there is a compression setting independent of the SSB compression setting - you can use any compression for SSB and set the RTTY compression to 1:1 for best transmit IMD. The only problem with this approach is that there may be a slight shift in the audio frequency of the received signal when you change to a narrow filter (up to 20 Hz). One can easily counter that shift by clicking on the Lock Transmit Frequency in the software before switching filters - that will keep the QSO from 'walking the band'. 73, Don W3FPR Logan Zintsmaster wrote: I hope the group will pardon me while I engage in a bit of RTTY heresy. When you use a PC sound card for decoding RTTY, the center frequency is no longer important, just the tone spacings. With MTTY, I can pick any center frequency I want to use (typically 1000 Hz so I stay away from the roll-off) and tune until I see it in the MTTY spectrum window. I make any fine adjustments with the cursor to pick the signal I want if there are multiple signals shown. If I want a bandpass filter, I use the bandpass function in MTTY. MTTY uses the same audio frequency for encode as it used for decode so the signal is inherently locked to the received signal. It even has an AFC function to track any drift. Using just the SSB filter for receive and transmit avoids the problem of center frequency tracking between the SSB filter that is always used on transmit and whatever receive filter has been selected. It also has the advantage of allowing you to hear what is happening across the audio bandwidth so you know whether to go higher or lower for the next signal. Very useful in a contest. I use Writelog with the MTTY decoder for contests and the whole setup works very well. Using the mouse wheel for tuning and macros for the exchange, I rarely touch the K2 at all. Hope this helps. 73 Logan, KZ6O ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 Harmonic Distortion
This discussion reminds me of some of the design choices I had to make when designing LP-PAN last year. I wound up using the SP-70 MILSPEC xfmrs, each driven by a pair of op-amps in a push pull configuration with zero ohm source. My original goal was to reduce 2nd harmonic distortion and improve response at frequencies approaching 0 Hz without the need for large capacitors in the output. The xfmrs are quite expensive, even in large quantities, but I have been very happy with the results.

In fact, it's at the point where my lowest distortion audio generator (HP 200CD) isn't good enough to measure a $4 transformer when driven by an op amp. I'm generator limited at -63 dB at the moment. I hope to improve that measurement floor in the next week or so. Driving the same transformer with a 600 ohm source Z brings you back to the 0.5% THD range.

[Elecraft] Re: K3: using data modes with MixW
Thanks for the helpful comments.I am now up and running using a mode change from SSB to data mode. In my application, both voice and data are SSB so no mode change was necessary.The specific trick was in MixW under the view menu, select spectrum and then check the box that says: RF, USB.After doing that, MixW displays an unchanged frequency from the K3 when the mode gets changed and the data ends up with the proper shift.

Re: [Elecraft] K3 Harmonic Distortion
As near as I can see from tracing from one sheet to another, U29, a TLV320ACC23 DAC with integrated headphone amplifier drives the TTC-108 LIN OUT transformers directly. Headphone and speaker audio, in contrast, are derived from a second TLV320 DAC driving a LM4950 amplifier for speaker output and an LM4811 for headphone output... Jack, I am coming into this discussion a bit late, so my apologies to all for any redundancy. I believe the device listed as U29 on the K3 schematic may be a mis-print and my best guess is that's it's the Texas Instruments TLV320AIC23 -- as is the case with U7. The device's H/P output (presumably used for the LINE OUT function) is rated to function down to nearly a zero-ohm load. http://focus.ti.com/lit/ds/slws106d/slws106d.pdf By contrast, the device's line-level output (unused on U29) is specified to function into a Z of no less than 10K-ohm. So, absent any large variation in noise level between the two outputs, Elecraft's choice of using the H/P output was a wise one since the transformers can be driven by a very low-Z. However, currently the TI device is coupled to the transformers with 600-ohm built-out resistors. Once you receive your TTC-108 transformers for testing, it would be an interesting exercise to incrementally change the value of the build-out resistors from a low-Z source -- all the way down to zero, and note the effect of THD/IMD sensitivity as a function of driving source Z. It would be an even more interesting exercise to run the identical test using the Triad transformer you mentioned as well as the Holy Grail of all audio line transformers, a Jensen type.

Re: [Elecraft] K3 Keying
Hi David: 1) More versatile CW generation features 2) More memories (in memory-type keyers) 3) More versatile CW memories (often) 4) Greater range of control These are my main reasons for using my Idiom Press CMOS Super Keyer (II/III/or IV) in deference to the K3's internal keyer.

RE: [Elecraft] K3 Keying
I use a Logikey K-3 external keyer because I find that it is just a little bit different than the internal keyer. I'm used to it and seem to make less mistakes with it so that't what I use. On the other hand when I had a K2 I found that the internal keyer was not nearly as good (for me) as the external keyer. With the K3 there is practically no difference at all (to me). I need all the help I can get. I'm old enough now that some days I have a little twitch in my hands. I would have no problem using the K3 internal keyer if my external keyer died or if I was away from my shack. 73, Roger, W1EM -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Cutter Sent: Friday, September 05, 2008 1:11 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Keying I would be interested to know why folks use external keyers in preference to the internal keyer.

David G3UNA Hi David, Generating cw directly from a (Windoze..?) pc is usually bad news. Windows always has priority and will interrupt cw keying when it needs to do something else; the result can be awful cw which can be embarrassing in a contest. Winkey takes the data from the pc as ascii (I think..) and generates it's own perfectly timed characters independantly of the computer with which to key the radio. A Microham keyer uses Winkey which also accepts paddle input - this means that the cw sent from your pc (eg from N1MM) will always be at the same speed and setup as that sent from the paddles, one speed knob controls both. I tend to use my Microham cw keyer all the time but admit the keyer in the K3 is excellent. 73, Stewart GW0ETF (K3 145) -- View this message in context: http://n2.nabble.com/K3-Keying-tp841765p841970.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'm wondering if you would want to change the PTT, lead-in and tail features on the fly, ie could these all be programmed in config? Running a standalone keyer in parallel with computer keying suffers from the disadvantage that input from the two sources is OR'ed, i.e. touching the paddle while the computer is sending CW results in unintelligible garble. One of the selling features of the WinKeyer for me was its integration of paddle and computer input. When the keyer is sending computer-generated CW, a touch of the paddle automatically interrupts computer-sent code and clears the input buffer. Thus, if you hit the wrong macro button in your software, you can start sending with the paddle instead and the PC-generated CW will stop instantly. This eliminates the need to first hit the ESC key on the computer and then switch to the paddle (or to PC keyboard CW). In fact, even if what I want to do is stop the computer output and then press the correct macro button on the keyboard, just touching the dit paddle still seems to be the easiest way for me to interrupt the output stream. Perhaps the K3 firmware will do this too, i.e. give priority to the paddle input over any of the other input sources: DTR on the serial interface, the straight key jack (which is often used for computer keying), or CW generated using the KY software command. I can't tell yet - I haven't found anything about this in the firmware release notes, and my own K3 arrived about two hours ago and is still just a collection of parts. Another feature of the WinKeyer has already been mentioned in this thread: the ability to configure it to add a constant keying compensation of a few msec to every element. Oh yes: will the K3's internal keyer autospace CW elements? That's a useful feature of many external keyers. 73, Rich VE3KI K3 #1595 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 Keying
The internal K3 keyer works fine, but I also prefer external keyer(s) for various reasons. I have both a WinKey USB and a LogiKey K-5 wired in parallel to the K3 key input. Most of my operating is CW contesting, and the WinKey generates great CW from the N1MM logging program. I have the LogiKey with its 6 memory buttons directly left of my keyboard, so it is pretty much just like an extension of the PF keys to call up one of those memories. I keep the LogiKey set to a lower speed than what I am using on the WinKey. That way, it makes slow speed fills of exchange elements quite convenient when signal levels/band conditions are difficult. I also program in some lesser-used items that I don't want to dedicate a keyboard PF key to. The downside of this, as Rich points out, is that you need to remember to hit ESC sometimes to avoid doubling with yourself. With my shack layout, the K3 is a much longer reach and the K3 memory buttons are in a cluttered panel area and in a vertical plane, making using them not very ergonomic - especially at 2 AM in a darkened shack. ...

Re: [Elecraft] K3 Keying
I think your suggestion would work if I tied the two PTT ouputs (one from K3 and other from the microHam CW keyer) together, isolating them with diodes. Another option would be to have a second set of paddles connected to the K3, for barefoot operation of the K3. I don't see any advantages to doing any of this-- at least for CW operation. The PTT, lead-in and tail features are easily changed in the microHam Router software, in DXBase, and N1MM. I do understand that I would need to use the internal K3 keyer if I wanted to take advantage of its ability to translate Morse into Baudot. 73, Chuck NI0C - Original Message - From: David Cutter [EMAIL PROTECTED] To: ni0c [EMAIL PROTECTED]; elecraft@mailman.qth.net Sent: Friday, September 05, 2008 1:06 PM Subject: Re: [Elecraft] K3 Keying Would it still work for you if you used your paddle directly into the K3 paddle input and pc into the key input, then the programs would still key directly?

I included an interface to key the radio[s], and inputs from the computer, bug, hand key, and paddle. Worked great with my K2 and TS-850. I built the interface to key both positive and negative lines and actually used that once on someone else's rig on FD. My only complaints were: 1. K1EL keyer lets me send commands in Morse. Sounds great ... not so much so when you are trying to change something in the middle of the contest. 2. K1EL keyer gives me two choices for weight. One is just a bit too crisp when I record my signal off the air, and the other is way too much. I got my K3 and HexKey. I now still have the external keyer plugged into the KEY jack so my computer can key the radio and my bug and hand key work. I use the 4 memories on the external keyer for stuff that doesn't change much or at all ... my call, QRL?, general CQ, etc. I have never used the K3 memories. TR-Log handles the memories for contests. External keyer weighting is still just a tad crisp for me on the K3. HexKey runs the internal K3 keyer. I can set the weight at whatever I want, I've got it just a bit less crisp than the external keyer and it's the paddle I always grab. I can QRS instantly with the front panel knob if someone calls me slower than my CQ. I always thought standard Benchers [with the spring] were really good. Then I got the HexKey :-) My K2 keyer very occasionally will seem to stutter. It's just discernible, and doesn't happen very often and isn't a problem, my sending isn't that well spaced anyway. I think every now and then the CPU has to do something more important than CW. Haven't noticed that at all on the K3 keyer.

RE: [Elecraft] K3 Keying
I got in the habit of using an external keyer before most rigs had internal keyers. As others have mentioned, external keyers are more flexible and quicker to set than internal keyers, so I continued to use an external keyer. When I first got into contesting in a serious way, I found that virtually all rigs with internal keyers had a conflict between internal and external keying. For example, on Yaesu rigs, the paddle and external keyer input use the same jack. The expectation is that if you use the internal keyer, a paddle will be connected to the jack. If you use an external keyer or PC, the hot lead will be connected to one of the two paddle inputs (usually tip), and the internal keyer will be turned off. You can parallel the paddle and external keyer or PC, but you can't use them together. If you have the internal keyer off, you can key with the external keyer or PC, but not with the paddle. If you have the internal keyer on, you can key with the paddle, but you get gibberish if you try to key from the external keyer or PC (which results in a keyer keying a keyer.) In the heat of a contest it's just not feasible to switch the internal keyer on and off when you want to use the paddle. Of course, the K3 has solved this problem by providing two separate inputs: one for the paddle and one for the key. Now I don't have to turn off the internal keyer to use an external keyer, and have the option of putting a second paddle on the K3 (I haven't done so.) There are other ways to solve the paddle problem in contests. Some contest programs support paddle input through the LPT port. That's one viable solution. The better solution is to use an external contest keyer. As others have mentioned, PC-generated CW isn't reliable on many computers due to Windows multitasking. An external keyer solves that problem, too. I use Writelog's W5XD+ keyer, which has paddle inputs and generates CW in response to commands from Writelog on the PC. It also does paddle, mic, PTT and audio switching for SO2R contesting. The keyer can also be used without Writelog running, though with limited functionality. There's a remote speed pot and L/R switch for selecting the rig. It's possible to build a switch to shift the paddle between the W5XD+ keyer and the rig (or two rigs, or three rigs...), but for me it's not worth the trouble. The W5XD+ keyer is adequate for my needs. 73, Dick WC1M -Original Message- From: David Cutter [mailto:[EMAIL PROTECTED] Sent: Friday, September 05, 2008 1:11 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Keying I would be interested to know why folks use external keyers in preference to the internal keyer.

Re: [Elecraft] K3 - Rtty Inverted with Mixw
I also had to reverse the setup in MixW2 from the setup I had established for the K2. I set MixW2 to use RTTYR in the Cat interface configuration window for the K3 and all appears correct - did not for the K2. I (think) assume it has to do with the difference in the RTTY and DATA mode between the K2 and K3.

It depends on the order of the harmonic. There are studio processors that INTENTIONALLY generate 2nd harmonic and add it to the signal. The control that adjusts the level is called warmth. :) 3rd order distortion is more audible and more objectionable. Higher orders become increasingly more audible and ojectionable, primarily because they are less musical! BTW -- the science of this is called physhochoacoustics -- the study of how we hear and perceive what we hear, and much is known about it. It is one of many disciplines that are part of the Acoustical Society of America, of which I am a member. 73, Jim K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Harmonic Distortion and Audio Intermodulation in K3's LIN OUT Port
I've completed a series of detailed measurements trying to understand why my K3's LIN OUT port exhibits greater distortion and anomalies than found in the headphone and speaker ports. Details are at http://www.cliftonlaboratories.com/elecraft_k3_receive_audio.htm What I found is that the 604 ohm resistor between U29's output amplifier stage and the TTC-108 transformer primary winding forces the TTC-108 isolation transformer to operate in a regime where the performance improving effects of a zero ohm driving source are not available. Hence, the TTC-108's 0.5% THD performance significantly limits the LIN OUT ports performance. I've also provided a theoretical parts value change that should improve the LIN OUT distortion and intermodulation. I have not implemented this change in my K3, but the external circuit mockup I used for testing strongly supports the change. I've supplied my measurements to the gurus at Elecraft for their consideration. If my data and recommendations make sense, I would expect confirmation from Aptos, after they have time to think it over and consider possible side effects.

RE: [Elecraft] K3 Keying
I've been thinking about hooking my K-3 keyer up too. I'm assuming none of the internal keyer controls work of course but wish/hope the NEW QSK default (reduces keying artifacts...) might still be effective. As it relates to the speed of muting/unmuting the rx, it seems possible. Gary W7TEA Roger Marrotte-2 wrote: I use a Logikey K-3 external keyer because I find that it is just a little bit different than the internal keyer. I'm used to it and seem to make less mistakes with it so that't what I use. On the other hand when I had a K2 I found that the internal keyer was not nearly as good (for me) as the external keyer. With the K3 there is practically no difference at all (to me). I need all the help I can get. I'm old enough now that some days I have a little twitch in my hands. I would have no problem using the K3 internal keyer if my external keyer died or if I was away from my shack. 73, Roger, W1EM -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Cutter Sent: Friday, September 05, 2008 1:11 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Keying I would be interested to know why folks use external keyers in preference to the internal keyer.

RE: [Elecraft] K3 TAPE ON DISPLAY
Unlike the K2, the LCD is pre-mounted on the front panel board and ready for mounting in the front panel assembly as described in the kit assembly manual. The last front panel board I received in the bag as it would be packaged in a kit was late last year. It had no tape on the display. Ron AC7AC -Original Message- Mike, It sounds like you could be a good test candidate. It is no more trouble to disassemble and remove it now than it will be later - why don't you see what happens over time and remove it if and when it becomes a problem. I do recall seeing something about a film being removed at Aptos because it was causing confusion among some builders, but I can't remember which film - so there may be no film on yours after all - but my memory may be faulty too. 73, Don W3FPR k4pi wrote: When assembling SN 1542 I never saw anything about removing the clear tape over the display. Anyone know of any problem there might be with leaving it attached to the display? I cannot see it now but possibly it might discolor with age. 73 Mike K4PI ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

They are not needed if all the interconnected gear is bonded together, and they are susceptible to magnetic fields. 73, Jim K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
