Re: [Elecraft] KPA500/KAT500/W2 order advice needed
Jeff, I am not sure why you want to locate the W2 directional coupler between the K3 and the KPA500, but that is your choice. As far as the high power coupler, what you wish to monitor will dictate where you place the coupler. If you place it between the KAT500 and the antenna, you would monitor the unmatched antenna shack end feedpoint with its raw SWR. If you place it between the KPA500 and the KAT500, you would monitor the matching condition into the KAT500, which should indicate a low SWR. The KAT500 SWR LEDs indicate the matching condition at the input of the KAT500 The KAT500 Utility can indicate the BYPASS SWR which is the unmatched SWR of the antenna feedline, so you can obtain the same information there as placing a coupler after the KAT500 - of course, you would need an extra serial port if you wanted to operate with the KAT500 Utility open on your computer. 73, Don W3FPR On 12/28/2014 11:45 PM, Jeff Hall, W6UX wrote: Hi everyone, I presently have a K3/100 hooked up to a P3 and a Microkeyer II. I want to add three new Elecraft products to my lineup: KPA500 amp, KAT500 tuner, and the W2 watt meter. There are many options listed on the Elecraft ordering page and I'm not sure if I have all the necessary cabling options selected. Additionally I need advice on which directional couplers I should choose for the W2. Here are the items currently in my shopping cart: - KAT500-K (High Power ATU, Kit) - E850463 (KAT500 to KPA Aux Cable) - KPA500-K (500W Linear Amplifier, Kit) - KPAK3AUX (KPA to K3 AUX Cable) - CBL36UHF (36 Coax cable) (three: K3-W2, W2-KPA500, KPA500-KAT500) - PWR-US240a (US 240V Power Cord) -- extra, for future use when I have a 240v line - W2-K (W2 Wattmeter, Kit) - DHCF-200 (0.1-200W 1.8-54MHz directional coupler) - DHCF-2000a (1-2000w 1.8-53MHz directional coupler) So, have I forgotten anything critical to get everything connected? The Microkeyer II uses the RS-232 port on the P3 and the ACC port on the K3. The KPAK3AUX cable Kit includes a Y-cable for the ACC port so that should make room for the Microkeyer II to be inserted into the rest of the K-Line gear. I picked the 0.1-200W directional coupler as I wanted to put the W2 between the K3 and the KPA500. Is it worthwhile adding the second coupler for 1-2000w? I'm assuming you only use this if you want to place the W2 after the KAT500? __ 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] P3 bug
I've seen this mentioned by others, but I don't think I've heard an official response. Sometimes the P3 'freezes up' for one to three seconds when returning to receive condition after transmitting CW. It doesn't happen every time, but enough to be bothersome, especially in a fast pileup. It is not caused by RF, because it happens in TX TEST mode. I have the VGA adapter, if that is related, although the freeze occurs on the P3 screen as well. To reproduce the problem, switch to TX TEST mode, and repeatedly send VVV at 25 wpm. The P3 will usually come back immediately after each group, but every few times it will stay frozen for a few seconds. -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ __ 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 have seen the same behavior as well. I'm away from my K3/P3, so I can't test it, but I think I have seen the freeze in AFSK A and SSB modes as well. I also have the SVGA installed in my P3. The behavior reminds me of the way the Apple ][ would go out to lunch every once in a while while the Basic interpreter ran garbage collection.

Hi Vic, If I remember correctly, there was a discussion here a few months ago, (which I can not locate in the archives for some reason), dealing with this behavior... I think it had something to do with telling the K3 to key down in two different ways...

Re: [Elecraft] What is REV next to VFO A LCD indicator?
Don, tnx on that times 2 definition of the REV button. Makes sense. It only took ten hours building the K3 kit but I suspect that I'll be learning more about the K3 throughout the spring! That makes the purchase even cheaper - all that fun built in! When I ordered the K3 I also ordered Fred Cady's K3 book, 2nd edition. I'm a math geek and retired engineer, so saddled with the curse of nearly always having to know (or derive) how stuff works...I'm currently pondering the secrets of the panadapter. Oh, by the way, grandkids bought me a Jawbone UP24 for Christmas. In fact, the whole family got one. We are now divided into teams and are already competing on who can register the most steps/day on average. You see, the Jawbone hangs on your wrist and counts your steps and activity. It sends it's data to your iPHONE via blue tooth and you can review your activity any time with the associated APP. Where this comes in handy with ham radio is that the Jawbone vibrates once if you sit for more than 30 minutes, just a reminder that you ought to get up and stretch or move.

Re: [Elecraft] P3 bug
Hi Vic, I have brought this up on the reflector. I have not given test mode a try but I will. It was strongly suggested to me that it was RF related but the problem crops up to the same degree at high power and running about 30 watts barefoot. I have also loaded up cables with ferrite clamp-ons and the problem persists to the same degree. Always intermittent and unpredictable. I also have the VGA adapter and the problem is visible on both the external monitor and the P3 screen. I have not tried removing he SVGA board to see if the problem persists. It was extremely annoying when I was operating as a W1AW/2 station working RTTY split. I depended on the P3 to direct my focus to stations in the clear.

Re: [Elecraft] P3 bug

Re: [Elecraft] P3 bug
It only happens here when the logging program (N1MM+) is active, which suggests it is related to traffic on the RS232 link - perhaps some kind of data collision which is being resolved by timeouts. N1MM Logger (both Classic and Plus) is extremely aggressive in its polling - something like 7 or 9 GET items - including FA; FB; and IF; all at once every 300 ms. Add a second polling source - e.g. the P3 - and the chance of collision, timeout, and/or buffer overflow gets fairly substantial rather quickly. 73, ...

[Elecraft] P3 Bug
I don¹t think it¹s in the SVGA, or at least not exclusively so. I have the identical experience with a P3 that doesn¹t have the SGVA option installed. Likewise I don¹t think it¹s a logging program hanging up a port - I don¹t use a logging program - in fact I have no computer connections to the rig at all other than briefly during firmware loads or configurations. Oddly, the hangups began for me just after I updated the F/W in both the K3 and P3 about six weeks ago (I am not at the rig now and so don¹t have the version numbers handy). Never happened before then.

Re: [Elecraft] P3 bug
Hi, I have seen this behavior with the SVGA as well. However, 1 or 2 seconds before the P3 returns is not the same issue that I believe most people are talking about. When I have had this issue the spectrum locks up and will not return until a subsequent transmit. The communications between the P3 and K3 will most likely take a bit of time when the transmission is finished. One to two seconds is probably the norm and I would think that this is normal behavior. Since the P3 and K3 use the same serial link, I would think that a faster response would be bad for other third party applications. In my opinion although I do not know for sure, I believe that what is happening is that the command issued to determine if the K3 is transmitting is very slow to receive a response. I have seen this in my software. Perhaps this combined with some code that needs a little additional work for the P3 / K3 communications might solve the issue. 73's Tom va2fsq.com -Original Message- From: Mike K2MK Sent: Monday, December 29, 2014 4:40 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] P3 bug I also have just proved conclusively that it has nothing to do with RF and nothing to do with a PC application.

[Elecraft] Remoterig k3/0 mini questions
While waiting for Elecraft to get back to me on this I thought I would ask here also. Along with the issue of the K3/0 mini not powering the remote K3 on just off, I noticed today that I can't get any audio drive out of the FP.L mic sel, I only get audio out of the rP.L mic sel. This is no big deal as I'm using a headset and can simply plug into the mic jack on the side of the K3/0 mini, still using the PTT from the main 8 pin foster connector. This of course would be a problem if I were to try using a desk mic. When I select FP.L I get no drive audio in the side mic jack, so I guess the hardware is ok. Anyone else seeing this behavior? I setup the control 1258 to try and control my K3 tomorrow from my summer home, that is 60 NMI away.

Re: [Elecraft] KPA500 clicking
I have clicking, but it doesn't following the keying. (Maybe you meant AFTER keying.) It happens after a long transmission...for the most part. It has to do with flexing of the heatsink or other parts of the chassis when the unit heats and cools. I believe it's been covered here before.

Re: [Elecraft] P3 bug
In order to reproduce this problem we are probably going to need much more information than has been given. To begin with, why don't you tell us what your update rate is set to on the P3, as well as what other devices you might have on the RS-232 bus? At 25 wpm you should be able to see the P3 update between letters, on a P3 w/o SVGA set to 20 ms update rate. I don't know what effect the SVGA option has, if any.

Re: [Elecraft] P3 bug
OK, Vic: the computer RS232 link is not involved. I hadn't noticed any hangups while testing with an external keyer using VOX (semi-breakin) but could easily create hangups using full QSK. That may be simply because full QSK generates many more TX/RX transitions. Sometimes even one dot was enough to cause a hangup. If something is marginal in the communication between the K3 and the P3, that might explain why the problem varies so much, both in the frequency of the hangups and in their duration. It might also explain why some people have never noticed it at all. Also, are we correct in believing that the problem only affects SVGA users? It's getting late here, but maybe someone could repeat the test with the SVGA display disconnected from the P3, in case that might be a source of disruption to the data communications. 73 from Ian GM3SEK -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Vic Rosenthal 4X6GP/K2VCO Sent: 29 December 2014 20:51 To: elecraft@mailman.qth.net Subject: Re: [Elecraft] P3 bug I have just tested it with and without a logging program running.

Nor have I. Perhaps an RF issue? 73, Jim K9YC I have the same problem and it does occur in TEST mode so it isn't RF. It is also a problem of long standing, not related to any recent firmware upgrade. The displays (both P3 and SVGA) hang at very irregular intervals, on average about once in maybe 10-20-30 returns to TX. Sometimes the displays freeze for only about a second, but sometimes for as long as 10 seconds or even more. I also have the impression that the problem sometimes occurs in 'streaks' when the probability seems much higher. Unfortunately the problem cannot be created on demand, only by repeated TX-RX cycling, but it does not seem to happen at all with purely manual keying. It only happens here when the logging program (N1MM+) is active, which suggests it is related to traffic on the RS232 link - perhaps some kind of data collision which is being resolved by timeouts. I have the impression that the displays become more likely to hang when the VFOB knob is rotated while transmitting on VFO A, which will feed a backlog of data into the RS232 link or its buffers. (FYI, my RS232 link uses the hardware COM1 port on the PC motherboard and the PC-P3-K3 chaining is exactly as specified in the manuals; the whole link functions perfectly in every other respect.) Although the problem seems to require that the logging program is running, it does not seem to be directly related to the source of CW and/or PTT. The problem occurs with manual keying and VOX, just as often as it does with keying from N1MM+ (DTR=CW, RTS=PTT). The same problem also occurs on RTTY but I'm not sure about SSB. 73 from Ian GM3SEK -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ __ 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 gm3...@ifwtech.co.uk __ 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] P3 bug
Hi Don, I've had this problem for several years and I only started using QSK this year. Further, the problem is also present when using RTTY (AFSK). I don't use SSB very often so I have not noticed if the problem is present with that mode. All firmware for the K3, P3, and SVGA are the latest, either production or beta. I run WriteLog for both CW and RTTY. But for the testing I just posted about I had no PC applications running and the K3 in test mode. My K3 settings are generally all default values. If there is something specific needed I can look it up and advise. I checked the refresh rate on the P3 and it was set at 10ms which is per the manual. I raised it to 20ms and the problem persists.

Re: [Elecraft] P3 bug
My suspicion is that the presence or absence of this problem has something to do with the K3 to P3 communication when the K3 tells the P3 that it is finished transmitting and is now in receive mode. If that communication is disrupted for any reason, the P3 would not begin its read of the IF spectrum. I am not any expert on how the internals of that communication happens, and we may have to wait until the K3/P3 engineers return from holiday vacations before we can see a response from them. In other words, wait until next week before expecting any meaningful responses. My input is purely a guess. 73, Don W3FPR On 12/29/2014 6:30 PM, Mike K2MK wrote: Hi Don, I've had this problem for several years and I only started using QSK this year.

Wes, The KPA500 T/R switching is all electronic, so no reed relays are involved. Are you certain the clicking noise is coming from the KPA500? There may be some audio from the speaker/headphones from the K3 when returning to receive. QSK OLD vs. QSK NEW might change the behavior unless it is truly coming from the KPA500 (which would likely indicate some mechanical effect - likely due to heating). The fact that you hear it in TX TEST mode indicates that it is not a heating problem, but check closely to determine if it is actually in the K3 audio on a return to RX from TX condition. 73, Don W3FPR On 12/29/2014 4:58 PM, Wes (N7WS) wrote: I'm a relatively new owner of a KPA500.

Re: [Elecraft] 240V Line
What Jim says here is correct. The old exception that allowed returning 120V loads to the bare or green grounding wire of a 240V circuit was very limited, allowed only for a few large appliances (dryers, stoves/ovens, and water heaters IIRC) which would be disconnected only for maintenance or replacement. The exception never applied to ham equipment. There are at least three possible Bad Things that can happen when you use a ground to carry operating current: (1) Some of the 120V load current returns by way of the coax, keying line, ALC line, the rig and its power supply, the antenna grounding system, etc.--anything connected to the amplifier chassis. This current often causes a stubborn hum in your transmitted signal (and other ill effects). (2) If the circuit has GFCI protection, the 120V load current is likely to trip the GFCI. (3) If the ground wire opens for any reason, the 120V load current has nowhere to go except the unintended paths, in particular through you if you are touching anything connected to the amplifier. This danger is the primary reason the NEC no longer allows combining neutral and ground conductors anywhere beyond the power service equipment (master disconnect enclosure). So if you have an older amplifier wired with 120V loads to chassis, it's wise to spend the time and money to make it safer and better by keeping the 120V load currents out of the chassis ground connections. --Tim (KR0u) On 12/24/2014 2:50 PM, Jim Brown wrote: You may be confusing a 120/240 outlet that has a four circuit plug (phase, phase, neutral, and Green) and can serve both 120V and 240V loads, with a 240V outlet that has a three circuit plug and serves only 240V loads. There is no neutral in a 240V outlet, and as noted above, it is illegal to connect a 120V load between one phase and the Green wire (Equipment Ground). That 120/240 circuit can feed both 120V and 240V outlets. A neutral IS required to feed those 120V outlets. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.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 Heat Sink Improved and Now Shipping -- Easy Retrofit to Existing KX3's
Hi all, In response to feedback from KX3 users, we have improved the transceiver's heat sink, without significantly changing its outside dimensions. The new heat sink has twice the surface area and much greater mass, using an 'L' configuration that places part of the heat sink underneath the rig's chassis. A high-performance, die-cut thermal gasket is used between the rear panel and heat sink to ensure excellent heat transfer. Our lab tests show that for a given power output level, the new heat sink provides up to twice as much transmit time as the original before power is automatically scaled back under firmware control. (Larger, third-party heat sinks can still be used, if desired, to allow extended operation in data modes at full power, or at very high ambient temperatures.) The new heat sink is already included in production KX3s, starting with S/N 7292 for kits, and S/N 7255 for factory assembled units. It can be easily added to existing KX3s using modification kit model #KX3HSKIT ($39.95). Refer to our Spare Parts and Mod Kits page, KX3 section: http://www.elecraft.com/order_form_parts.htm#kx3 If demand is high for modification kits, there may be a brief delay in filling orders. 73, Wayne N6KR __ 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] P3 Bug
No SVGA (and no computer link) here, yet the problem happens now and then - often enough to be annoying - just as others have described it. I am almost sure I am using QSK ³old.² The K3 is about 100 miles from where I am right now so I can¹t confirm that. While I am not 100% sure of this, it may be that the recovery delay has happened only when working split with the sub RX enabled. On the other hand, that would be the only time I would care about it since it would be the only circumstance in which I would be trying to use the P3 to position my transmissions, so my perception may be skewed.

Re: [Elecraft] M1 -M4 reports NO DVR for data mode on 30 and 17 meters only
No, not running split. Ah ha! I figured it out. NR4C sent an email asking me about which DATA Mode I was using. I found that 30 and 17 meters were setup for AFSK rather than FSK as I use on the other bands (my paddle speed and accuracy is much better than using a keyboard!) So that solves it. And I guess I also learned that if I were to want to use a different mode like AFSK or DATA, I would need the DVR module for the memories. Nice.

Re: [Elecraft] KPA500 clicking
More on this mystery. The sound is also audible in the K3. It is definitely mechanical and only happens (in both units) when the Aux cable is connected and the KPA is in Operate, in other words when it goes into or out of transmit. The Speaker is Off in the K3, the sound is NOT audible in the headphones. It happens in either QSK or Semi. I can also hear a single click when going into or out of Tune.

Re: [Elecraft] P3 bug
I have seen the P3 SVGA lockup on voice. It remains this way until the next transmission. However, I never paid attention to the P3 itself during this. I only looked at the svga output. Does the P3 hang as well? If it does, then it is most likely an issue with communications between the K3 and the P3. If the SVGA output is the only one to freeze, it is most likely the firmware in the SVGA / P3 at fault.There were some issues in the past with the P3 corrupting the communications between the K3 and itself. This was fixed. However, it could still be in some ways related. Just like the P3 does not always respond to a marker QSY. The lockups are known to Elecraft. This was reported by me and discussed with an engineer over two years ago. This and a number of other bugs such as no averaging on the SVGA, the VFO B marker not responding to changes in the IF shift, and quite a few more. I guess there is just not enough staff to deal with these issues. I therefore offer, as a volunteer, to fix these errors if Elecraft agrees. -) 73's Tom __ 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] KPA500 clicking
RF may be switched with PIN diodes, but there are some relays in there someplace. No TR relay. Amp is quiet as a mouse when keying/unkeying, even in QSK. There IS a STBY/OPER relay, I assume, as I can hear it when I go in and out of OPER. Also, band switching, of course. There are ticks due to heating in the heat sink, but not in time with keying. Random, and varying rate. Documented on this group previously. Have you asked Elecraft (not this list) for a diagram?

Re: [Elecraft] KPA500 clicking
What you are hearing is due to magnetostrictive force causing the windings of the inductors in the TR switch to bang against their cores as the TR switch bias is applied. There are no relays. 73 Bob, N6CM, KPA500 design engineer. On Mon, Dec 29, 2014 at 10:23 PM, mcduf...@ag0n.net wrote: RF may be switched with PIN diodes, but there are some relays in there someplace.

[Elecraft] A Heartfelt Plea
I know that I am new to this list but I’d like to make a plea from the heart (I will be posting the same plea on some other groups): Would list members please, please, please think about what they are doing when they quote an entire message (and sometimes many, many replies) when posting to the list. Sometimes there are quotes of quotes of quotes and the content is actually just one line! In the main, I read this list on my phone and I sometimes find it almost impossible sometimes to actually find the intended content! What’s wrong with editing what you’re going to quote - and perhaps using snip to show that you’ve done it? Thank you for reading this and I hope that it will have a positive effect. 73 David G4NRT __ 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
