[Elecraft] K3 - How to turn off internal speaker
Something changed in my K3 Config, use to have the internal spkr off for use with external noise cancelling speaker. This has to be the dumbest question ever asked, How to turn off internal spkr?

Re: [Elecraft] switching VFO A knob to B VFO
Hi Todd, Of course Oliver is correct and I would like to add one comment. For the W1AW/n operations be sure to lock VFO B. You don't want your transmit frequency to change if you accidentally reach for and rotate the VFO B knob. 73, Mike K2MK Oliver Dröse wrote Hi Todd, simply switch SPLIT on and it will work exactly as you described. ;-) In SPLIT mode VFO A is the RX frequency while VFO B is the TX frequency. Have fun with the pileups! 73, Olli - DH8BQA Am 19.12.2014 um 18:17 schrieb todd ruby: Is it possible when operating split to use the larger A VFO knob to control the B VFO and the smaller B knob to set the A VFO freq? I am asking this as I will be operating W1AW/3 and if I have to work split it would be easier to leave the xmit freq controlled by the smaller knob and tune the “spread” with the large VFO A knob. 73 todd WB2ZAB -- View this message in context: http://elecraft.365791.n2.nabble.com/switching-VFO-A-knob-to-B-VFO-tp7596159p7596177.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 Message delivered to arch...@mail-archive.com

I am guessing that you are using the phone jack for the external connection - if so, turn off Speaker + Phones in the menu.

Re: [Elecraft] K3 - How to turn off internal speaker
Additional caution DO NOT plug a mono plug into the speaker jack. A stereo plug must be used, even with a mono speaker. Two speakers are nice, and allow use of the several versions of audio phasing effects. 73 Ken - K0PP On Dec 20, 2014 6:54 AM, Don Wilhelm w3...@embarqmail.com wrote: I am guessing that you are using the phone jack for the external connection - if so, turn off Speaker + Phones in the menu.

Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem
I doubt your problems are because of the firmware, but the answer about the best version of firmware to use is to always load the latest production version. Beta versions can be useful if you are experiencing problems that the beta release corrects. Remember that beta versions are usually OK to use, but there are made available so a large number of users can report any problems they experience. If there are no problems reported, that beta version will be advanced to production status. OTOH, if there are problems reported, that beta version will be replaced by another beta with those problems addressed. 73, Don W3FPR On 12/19/2014 10:31 PM, Va3ied wrote: I just bought the tuner and am having the exact same issues on 80 mwhat veh of firmware works best? __ 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 Message delivered to arch...@mail-archive.com

However, from what I’ve read, adjustment is very sensistive and it is more susceptible to hum , RF pickup, etc. And you have to deal with how your computer handles the audio (mixers, audio enhancement, etc.) The SignaLink is a good, simple, reliable interface, well worth it IMO.

[Elecraft] K3EXREF problem
I just installed the K3EXREF option and followed the step-by-step instructions. I'm feeding it with a +10dbm level from my HP Z3801 disciplined, 10MHz reference. The K3 doesn't appear to be locked. The Installation and Operation manual says that LOCKED will appear if you try to adjust the VFO A knob but that doesn't happen. Checking the frequency with WWV by using another radio in AM mode and comparing it to the K3, I can hear a beat note.

[Elecraft] Elecraft KX3 IQ out and spectral display pograms
Greetings and happy holidays Elecraft enthusiasts. I have been putting together a portable contest/dx station using a KX3/KXPA100 combo. What a wonderful little setup. As part of my testing process, I have setup a laptop computer for rig control. This works great in alot of respects, Cat control.. no problem. Keying cw from the computer.. no problem. I have run into a tiny issue, regarding the IQ out and how it integrates with computer based spectral display applications and I am hoping the fine brain trust of audio experts can help me out. I have a creative EM 0204, and I have split out the IQ stereo into 2 channels using a 1/8 stereo to mono a/b splitter, and subsequently feed IQ to the EM 0204 into the L/R mono ports. I am having some issues that I have not run into.. for instance when I used to do this using an N8LP pan with my K3. (I have done sufficient testing with other computers, sound cards to be aware this is not limited to just this equipment). here is what my observations are: CW Skimmer. Seems to work.. but the IQ balance seems to fall out of sync after being dialed in. in other words from time to time multiple traces of signals appear. this after adjusting with a fixed carrier on WWV to remove the traces. Its almost as if there is an IQ instability of some kind and I was curious what others have found. PAN displays, NAP3, etc.: there seems to be a rather large artifact that tracks with the center frequency making use of the pan display rather impractical...maybe 20-30 Kc's or more.I assume this issue is resolved to make the PX3 display an accurate spectral representation, and so am wondering if there must be a setting or something I have adjusted incorrectly. I also ran into an audio artifact where I could hear computer rfi through the headphones with the IQ cable plugged in.. I was able to mitigate this using a ground loop isolation cable.. keeping in mind I want to keep this setup portable and useable in remote locations. IF anyone who may have resolved some of these IQ out issues could chime in and assist it would be greatly appreciated. I am trying to make this setup as capable and portable as possible. thanks in advance and look forward to your responses.

Re: [Elecraft] New K3 beta firmware release, rev. 5.01: Much-improved audio during CW keying
Graham, I agree. And I also hear a transient click albeit it far better than before. Since you hear it as well, I have to ask you if you hear it on the right side, not the left, If you play a character slowly, do you hear it at the end of the character and if it goes away completely if you engage the sub Rx? This is what I have found with my K3. 73, Gary KA1J Yes, it's a significant improvement. There's still some slight transient click but much better. Well done Elecraft!

[Elecraft] [K3] Detuning antenna per band and QSK
I use and like QSK on my K3 but I'm now looking at detuning my 160 inverted L to avoid reradiation into my beverages when in receiving. I'm looking at what it will take to do that and it appears that if the 160 inv-L is just deselected by the remote DXE relay box it will just be an ungrounded 1/4 wave which shouldn't present problems on 160. I could implement a sequencer in the shack to do this by interrupting the relay select line that controls the 160 antenna on a per band basis but that leaves the question of what to do about QSK since the relay is specified to operate no sooner that 15mS. That will likely impact the clean CW and be undesireable. I can decode the band info and get the info about whether it is in TX or RX mode and probably inhibit the K3 until the delay has expired. But I'd need to kill QSK on 160 alone to do this. Is there a way to do QSK on a per band basis? 73 jim ab3cv __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms
Thanks Barry.. I am not having rig control issues and thus dont need to use LP-bridge at this time. This seems specific to the IQ audio coming out of the IQ out of the KX3. I have experienced this on 2 KX3's and multiple sound card/computer combinations so I suspect an internal setting or something I have not found documented or missed. Since the PX3 is in existence.. there must be some setting/combo that fixes the spectral display as it is fed to a high end sound card. and again I did not have this issue with the N8LP pan or the IF out of my K3's. This is specific to the IQ out feature of the K X 3. If you read further you will find I did solve some of the computer RFI with a GLI.. in particular from radio shack. This seems to be required hardware at this point and needs to be put in line with the IQ out cable provided by elecraft. With it in line it is no longer a problem. Thanks for the tip on Win4k3 Ill give that one a shot. ~C./WM From: Elecraft [elecraft-boun...@mailman.qth.net] on behalf of Barry LaZar [k3...@comcast.net] Sent: Saturday, December 20, 2014 12:42 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms Chris.

I have run into a tiny issue, regarding the IQ out and how it integrates with computer based spectral display applications and I am hoping the fine brain trust of audio experts can help me out. I have a creative EM 0204, and I have split out the IQ stereo into 2 channels using a 1/8 stereo to mono a/b splitter, and subsequently feed IQ to the EM 0204 into the L/R mono ports. I am having some issues that I have not run into.. for instance when I used to do this using an N8LP pan with my K3. (I have done sufficient testing with other computers, sound cards to be aware this is not limited to just this equipment). here is what my observations are: CW Skimmer. Seems to work.. but the IQ balance seems to fall out of sync after being dialed in. in other words from time to time multiple traces of signals appear. this after adjusting with a fixed carrier on WWV to remove the traces. Its almost as if there is an IQ instability of some kind and I was curious what others have found. PAN displays, NAP3, etc.: there seems to be a rather large artifact that tracks with the center frequency making use of the pan display rather impractical...maybe 20-30 Kc's or more.I assume this issue is resolved to make the PX3 display an accurate spectral representation, and so am wondering if there must be a setting or something I have adjusted incorrectly. I also ran into an audio artifact where I could hear computer rfi through the headphones with the IQ cable plugged in.. I was able to mitigate this using a ground loop isolation cable.. keeping in mind I want to keep this setup portable and useable in remote locations. IF anyone who may have resolved some of these IQ out issues could chime in and assist it would be greatly appreciated. I am trying to make this setup as capable and portable as possible. thanks in advance and look forward to your responses.

Re: [Elecraft] [K3] Detuning antenna per band and QSK
Another way to do what you want might be to switch some attenuation into the receive path during transmit. I assume you are using the RX antenna port for the beverages.

Re: [Elecraft] PX3 decode missing characters that are displayed on the KX3
Fred, That is a good question. Until you asked it, I didn’t notice that if the KX3 Utility is *NOT* running, the PX3 copies fine. If the KX3 Utility is running both the KX3 Utility terminal and the PX3 have bad copy. The copied text in the KX3 Utility terminal and the PX3 don’t match either. I also noticed that if keep the KX3 Utility running and click off of the terminal tab (say the port tab), the copy between the KX3 and the PX3 match again. As soon as I click on the terminal tab in the KX3 Utility, the PX3 copy stops working again. My plan was to send text using the KX3 Utility terminal and copy text on the PX3. Should this work with the PX3? I’m running KX3 Utility version 1.14.4.11on OSX 10.10.1. The KX3 and PX3 have the latest production firmware.

[Elecraft] K2 SSB Performance Improvement
Other K2 owners may be interested in this. After getting many reports of poor quality transmit audio with my K2 (using the Proset K2 Heil boom microphone and headset), I carried out the modifications described by G3RXQ which increase the lower cut off frequency of the microphone circuit on the KSB2. This involves changing C34 from 2.2uF to 1uF, C31 from 2.2uF to 1uF and C20 from 0.33uF to 0.1uF. Now, when I listen to my transmitted signal on another receiver, the audio now sounds much crisper with increased high frequency content. I have also had many comments on the high quality of my audio and even someone reporting BBC quality audio. Well done G3RXQ! I also spent considerable time trying to optimise the Tx BFO frequency by listening to my transmission on another receiver. After many hours of careful BFO adjustment I finally ended up with the exact BFO frequency settings recommended in the KSB2 manual.

Re: [Elecraft] Using Yaesu FT-991 with KPA500
Hi Roy, Found a copy of the Owner's Manual for the Ft-991. The short answer to your question is, yes, there appears to be BCD Band Data Lines on the Ft-991's 8-pin Mini DIN connector labeled for Linear. Actually, the connector and pin out definitions appear to be exactly like the FT857/897 series of radios, too. I believe you'll need to make a MENU change in order for it to work, too. See Page 12 in the Owner's Manual for wiring for Basic mode operation with the KPA500. Yaesu seems to hint that there's a cable available for that connection method - most likely through their parts department. See page 21 for a definition of the Linear port. I suspect there's a pin-out diagram in the back of the manual that will match the Yaesu pin out table in the KPA500 Owner's Manual for the Band Data signals.

Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms
Hi I have worked with someone who had a similar issue. In his case the iq signals were randomly swapping and that of course can ruin any balance that has been set. I have read recently of others on the kx3 yahoo group which report the same thing. Extensive troubleshooting was done. It was not the software package in use. It did this with all. In the case where I helped out the only thing that solved it was using a different computer. The problem never returned. We did determine though that high processor usage eliminated the problem. That's right, go figure. It's a mystery. Tom On Dec 20, 2014 3:52 PM, Chris Tate - N6WM ct...@ewnetinc.com wrote: Thanks Barry..

Re: [Elecraft] PX3 decode missing characters that are displayed on the KX3
I suspect that the PX3 and KX3 Utility are both using the TB; command to poll the KX3 for incoming text. Since the KX3 clears the buffer after responding to a TB; command, this would cause bad copy on both the PX3 and KX3 Utility. Text displayed in the Utility would be missing on the PX3 and the text displayed on the PX3 would be missing in the Utility. This is just a guess. I may be dead wrong.

Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms
Perhaps the problem is due to noise on the computer ground. The PX3 has differential amplifiers at the I/Q inputs. For the computer-based panadapter, it might help to connect the grounds of the computer audio input connectors to the KX3 ground with a short, large-diameter wire. Another possible solution would be to use audio isolation transformers on the I and Q signals to isolate the grounds. That will cause a notch in the panadapter response. The notch width will be twice the transformers' low-frequency cutoff frequency. Alan N1AL On 12/20/2014 11:13 AM, Chris Tate - N6WM wrote: Greetings and happy holidays Elecraft enthusiasts.

Its almost as if there is an IQ instability of some kind and I was curious what others have found. PAN displays, NAP3, etc.: there seems to be a rather large artifact that tracks with the center frequency making use of the pan display rather impractical...maybe 20-30 Kc's or more.I assume this issue is resolved to make the PX3 display an accurate spectral representation, and so am wondering if there must be a setting or something I have adjusted incorrectly. I also ran into an audio artifact where I could hear computer rfi through the headphones with the IQ cable plugged in.. I was able to mitigate this using a ground loop isolation cable.. keeping in mind I want to keep this setup portable and useable in remote locations. IF anyone who may have resolved some of these IQ out issues could chime in and assist it would be greatly appreciated. I am trying to make this setup as capable and portable as possible. thanks in advance and look forward to your responses.

Re: [Elecraft] PX3 decode missing characters that are displayed on the KX3
That's correct. You can copy decoded text using KX3 Utility or on the PX3 screen, but not both at the same time. Alan N1AL On 12/20/2014 03:12 PM, David Fleming via Elecraft wrote: I suspect that the PX3 and KX3 Utility are both using the TB; command to poll the KX3 for incoming text. Since the KX3 clears the buffer after responding to a TB; command, this would cause bad copy on both the PX3 and KX3 Utility. Text displayed in the Utility would be missing on the PX3 and the text displayed on the PX3 would be missing in the Utility. This is just a guess. I may be dead wrong.

Re: [Elecraft] PX3 decode missing characters that are displayed on the KX3
Thanks for the info about not running the PX3 decode at the same time as the KX3 Utility terminal. Since I’m using the KX3 Utility terminal for text entry, I’ll use it for decode as well and turn off the text decode on the PX3. phil (K4PMI) __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] Detuning antenna per band and QSK
I suggest using a vacuum relay at the antenna. I wouldn't want to switch a relay box even with a sequencer at a semi-QSK rate.

I'm looking at what it will take to do that and it appears that if the 160 inv-L is just deselected by the remote DXE relay box it will just be an ungrounded 1/4 wave which shouldn't present problems on 160. I could implement a sequencer in the shack to do this by interrupting the relay select line that controls the 160 antenna on a per band basis but that leaves the question of what to do about QSK since the relay is specified to operate no sooner that 15mS. That will likely impact the clean CW and be undesireable. I can decode the band info and get the info about whether it is in TX or RX mode and probably inhibit the K3 until the delay has expired. But I'd need to kill QSK on 160 alone to do this. Is there a way to do QSK on a per band basis? 73 jim ab3cv __ 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 Message delivered to k2vco@gmail.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 Message delivered to arch...@mail-archive.com
[Elecraft] [KX3][2M] Assembly Advice - Going Nuts!
I am installing my third 2M module on a KX3 for a friend. On this particular unit, the nut that I guess was being held on by some adhesive I never noticed, fell off the back of the FET heat sink. I’m having a stickler of a time trying to figure out a clever way to hold the nut on there so I can re-insert the board and get the lock screw through the side of the case. (Figure 20, Page 27) Any wise men around have any sage advice? /ponder Chris K6OZY __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms
Why? It's an unbalanced interface! Yes, that's the problem. The power supply in the computer probably has bypass/filter capacitors between the line and the chassis. So with an unbalanced connection to the KX3, there will be 60 Hz (and harmonics) AC current flowing in the cable shields. Even a fraction of a millivolt voltage drop in the shield is enough to cause a visible 60 Hz spur on the panadapter display. The voltage drop can be reduced by connecting a short, low-resistance wire between the two chassis. I suggested making the connection on the computer end to the audio connector shells to make sure you're connecting to the ground reference of the sound card, which might be different from other points on the chassis. That may have been bad advice - I'm not an expert on the construction of a typical PC chassis. But I think isolation transformers would be an even better solution. That should completely eliminate hum caused by different voltages on the two chassis. The PX3 uses differential sensing on the I/Q inputs instead of isolation transformers. In effect, the PX3 ground reference is the KX3 chassis, rather than the PX3 chassis. That way, even if there is a 60 Hz voltage difference between the two chassis, it won't cause interference. This is smelling VERY much like Pin One Problems. For those who aren't familiar with the term, the so-called pin one problem is when the ground pin on a connector is not connected directly to the chassis but rather via a wire, PC board, etc. I believe the name comes from audio XLR connectors, which use pin 1 as the ground. The pin one problem normally shows up at RF frequencies because of the inductance of the internal ground connection. But the issue under discussion is 60 Hz interference, so I doubt that that's the problem.
