Re: [Elecraft] KPA500 Issue
Yes, that was the problem when it happened to me. It was a cable problem that was inadvertently closing the key in (PA Key) input on the back of the KPA500.

Re: [Elecraft] KPA500 Issue
Hi Barry, While your experience suggests that a transistor switch will probably save the day I also wonder if the problem is the result of the absence or presence of a pull-up resistor or perhaps a floating common connection between the rig and amp. Maybe a resistor in the plug would help. I suppose there is some way to check this out. 73, Mike K2MK Barry Simpson wrote .partial quote from Barry.. The conclusion is therefore that from an initial OK position in Stby and Oper as soon as the first character is keyed, the solid state switch in the TS590SG hangs resulting in the KPA500 being permanently in the transmit state. The situation only clears when rig and amp are turned off, the Din plug is removed from the TS590SG and reinserted and both are turned back on. I can then switch the amp back to Oper and all is fine until the very first morse character when it all happens again. So as it stands, there appears to be incompatibility between the TS590SG solid state amp switch and KPA500. As an interim measure, I have rewired the Din plug to use the noisy relay for the amp control and that works fine. The TS590SG does output 12V to the solid state switching pin in certain configurations as did the TS590S. I had a TS590S and I wired a single transistor solid state switch inside the Din plug and that worked perfectly so I am going to do the same again, which should solve the issue. Unfortunately, I gave away the TS590S cable I had made up to the guy I sold the TS590S to. I never got the very bad spike issue fixed but the buyer did not mind as he doesn't use a linear. It really is a pity as I thought that the new linear switching circuitry in the TS590SG was a real step forward but it is not to be, at least not with the KPA500. 73 Barry VK2BJ -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-Issue-tp7597707p7597728.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
Re: [Elecraft] Separate Receiving Antenna
I'm using a Pixel Loop as a receiving antenna to supplement my main t/r antenna, which is an R8 vertical. The only 'garden' I have is a rooftop about 35 m above ground. The antenna is about 6 m from the vertical and definitely has a better s/n ratio. I use it on HF bands, sometimes by itself and sometimes for diversity reception with the K3's subreceiver. It isn't a panacea for noise problems but definitely helps. The diversity mode is also a big help despite the small separation between antennas. The Pixel Loop comes with a device that makes it possible to 'key' it along with the transmitter in order to protect the receiver. I am using this successfully with QSK at 1.2 kW output. The relay is noisy but fast enough at reasonable speeds.

Re: [Elecraft] KPA500 Issue
when I switch it from Stby to Oper, the level of received signals drops by around 5 or 6 s points. It still transmits fine and there are no adverse SWR indications or loose co-ax plugs.

Re: [Elecraft] KPA500 Issue
Good morning to those who responded to me on the Elecraft reflector. Here is the interim outcome. I did not mention that the problem arose after connecting my brand new (yesterday) TS590SG to the KPA500. The TS590SG has different linear switching facilities from the TS590S in that there is now provision for solid state switching to avoid a clicking relay. I was using the solid state switching set up. I use the same set up with my TS990S and that works perfectly with the KPA500. I checked and resoldered the connecting cable and then I interchanged the cable I use with the TS990S as the Din pin connections are identitical with the TS590SG. The outcome was exactly the same with the loss of received signals when the KPA500 is switched to Oper and the little asterisk appears on the left side of the display. However, the set up still keys the KPA500 perfectly. I then changed over to the TS990S and with that rig, the KPA500 works perfectly with the solid state switching. The conclusion is therefore that from an initial OK position in Stby and Oper as soon as the first character is keyed, the solid state switch in the TS590SG hangs resulting in the KPA500 being permanently in the transmit state. The situation only clears when rig and amp are turned off, the Din plug is removed from the TS590SG and reinserted and both are turned back on. I can then switch the amp back to Oper and all is fine until the very first morse character when it all happens again.

It really is a pity as I thought that the new linear switching circuitry in the TS590SG was a real step forward but it is not to be, at least not with the KPA500. For information and to avoid others having a similar head scratching issue, I am copying this to the TS590 list as well. As a final point, I can confirm that the TS590SG has no power spike issue whatsoever and the average audio level in SSB seems much improved from the TS590S. Once I have wired and implemented the transistor switch, I will report back with the result. 73 Barry VK2BJ On 31 January 2015 at 00:34, Mike K2MK k...@comcast.net wrote: Hi Barry, There is an asterisk that appears on the left side of the KPA500 display whenever the key out signal from your transmitter is present.

Re: [Elecraft] SVGA NB doesn't always start latest beta f/ware
Hi Jim, I can't have explained myself very well. The NB is working (level 10) on the P3 but on the VGA output the NB on state is not remembered on switch off. So if I turn the P3 off and then on again, the NB works fine on the P3's own display, but to make it work on the external monitor I have to turn the NB off then on again. Reference to NB here is solely the P3. Hope that makes sense. I have been using the NB on the P3's screen for some time now, but it is only the latest beta I think that extends this functionality to the P3's VGA output, and that is the version I'm running. 73 Stephen G4SJP On 30 January 2015 at 17:54, Jim Brown j...@audiosystemsgroup.com wrote: On Fri,1/30/2015 9:43 AM, Stephen Prior wrote: Turning the NB off and then on via the P3's menu restores functionality.

Anyway, Em was also a wine maker, but at the other end of the spectrum from Ed. Em made his own stuff, and was only somewhat proud of it. He also ran a gift shop/printing shop combination, and so he printed up his own private brand labels for his homebrewed wine.

Re: [Elecraft] (K3) Alexloop Antenna
I've had an Alex Loop for about 2 years now, it replaced my Buddipole [about the same cost]. You can build your own mag loop for a lot less than the Alex but I wanted the cool carry case and had the $$ from the BP sale. :-)) I use the loop when activating a SOTA summit and general field operating, usually with my K2/10. My Alex easily works as well or discernibly better than the BP ever did. It is very narrow BW, and tuning it on 40 requires a steady hand and care. It's less touchy on 30 and just fine on 20 and up. I have mine on a light-weight tripod I found at Home Depot with a Rain Bird sprinkler on top. I cut 9 inch piece of 1/2 gray PVC nipple with threads on one end and screw it into the tripod. The hollow Alex handle fits down over the PVC. I finally filed some shallow slots in the PVC to keep things stable in wind. I set up next to the tripod and can reach up and tune the loop with one hand. There is one gotcha with loops like this: It is a resonant transformer. At resonance, your SWR will be 1:1 and you'll make Q's. If you get it close with the knob and then let the ATU [if you have it] match it, you will have created a very well shielded dummy load and you'll make no Q's. So, bypass the ATU and get 1:1 with the little knob on the capacitor. You can't QSY more than maybe 5 KHz on 40 without tweaking the capacitor. BW gets larger on 20 and up. It is mildly bi-directional in the plane of the loop but the lobes are quite broad. There are two very sharp, fairly deep nulls orthogonal to the loop plane which can sometimes help reduce noise or QRM. It is essentially insensitive to ground, and doesn't really care how high it is, a tremendous advantage in the field over E-field antennas. Pay attention to the power limits. Because it is resonant and small in terms of electrical degrees, RF voltages can get quite high. It's definitely a QRP antenna. Hope this helps, 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 1/30/2015 12:47 PM, David Guernsey via Elecraft wrote: I live in a condo with pretty strict rules re antennas, etc. I am considering an Alexloop on a tripod on my balcony, Does anybody have any experience with this antenna?

[Elecraft] Issues with TS590SG and KPA500 - the outcome
I have already posted details of the issues I have experienced trying to interface my brand new TS590SG with my KPA500. The TS590SG has different linear amplifier switching arrangements from the TS590S and these mimic the TS990. Specifically Menu 59 #4 provides solid state grounding via pin 7 of the remote connector for switching linears. I use this method with my TS990 and it works fine. However, it does not work with the TS590SG and the KPA500 goes into the transmit state permanently once it is put into the operate position. The relay switching Menu 59 #2 works very well but it is noisy. Feedback I have received suggested that I try a diode in series with the keying line. I tried it but absolutely no difference. Another suggestion was a pull up resistor but I wasn't sure what to install and where. Clearly in its original state, the solid state switching is incompatible with the KPA500. I have now reverted to the method I used with my earlier TS590S which is a single transistor switch - a 2N3904 and a 2.2K resistor squeezed into the shell of the Din plug. The connection to the TS590SG is via Pin 7 and the setting is #1 which provides +12v on transmit which is what the TS590S also does. Suffice to say that this solution works perfectly and silence now reigns again. Hopefully either Kenwood or Elecraft will devise a simple solution to the problem in due course. Just an update which others may find of some help.

The simplest workaround is to use AFSK.

[Elecraft] KPA500 Issue
My KPA500 has just developed an issue. Specifically when I switch it from Stby to Oper, the level of received signals drops by around 5 or 6 s points. It still transmits fine and there are no adverse SWR indications or loose co-ax plugs. It does the same on all bands. I switch back to Stby and the received signals return to normal. I seem to recall that someone else posted details of a similar such problem some time ago. Any suggestions would be helpful before I email the Elecraft hot line.

Re: [Elecraft] Shift waterfall with P3
Glad I could help From: Gary Smith g...@ka1j.com To: Elecraft@mailman.qth.net Sent: Friday, January 30, 2015 1:17 AM Subject: Re: [Elecraft] Shift waterfall with P3 Harry, Apparently I hadn't. I had calibrated the K3 recently but missed that in the P3 menu. It is now properly calibrated and thank you for the pointer. 73, Gary KA1J Have you looked at the Ref Cal option in the menu? From: Gary Smith g...@ka1j.com To: elecraft@mailman.qth.net Sent: Friday, January 30, 2015 12:07 AM Subject: [Elecraft] Shift waterfall with P3 I've noticed something happening with the P3 that I haven't found a way to resolve. The K3 is hearing a station on 1.825.010 Pushing spot verifies this is the optimal frequency I'm hearing them at. I have the P3 span sat the narrowest at 1. The centerline of the P3 displays 1.824.97 Pressing CENTER on the the P3 says Center Frequency 1.825.0 However, the signal is decidedly to the left of the center line on the P3 display. The peak of the signal is above the signal, not at 1.825.0 It seems as if I could move the waterfall to the right 110 Hz, both would be in sync. I can't seem to find any mention of an adjustment to get these in sync. Any suggestions? 73, Gary KA1J --- 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 hlyin...@yahoo.com --- 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 hlyin...@yahoo.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] K3 SO2V in digital modes
It seems the current firmware will not allow me to use FSK on VFO A and PSK63 on VFO B. The annual national contesting series in the UK has a monthly event that is RTTY + PSK. What is the status of any firmware change to allow digital mode per VFO on the K3? Meantime are there any workarounds? 73 David G3WGN M6O WJ6O __ 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 Issue
Hi Barry, There is an asterisk that appears on the left side of the KPA500 display whenever the key out signal from your transmitter is present. You should not see the asterisk when you are receiving. If you are then is it possible that you are using the key out signal to operate some other device in addition to the KPA500? 73, Mike K2MK Barry Simpson wrote My KPA500 has just developed an issue. Specifically when I switch it from Stby to Oper, the level of received signals drops by around 5 or 6 s points. It still transmits fine and there are no adverse SWR indications or loose co-ax plugs. It does the same on all bands. I switch back to Stby and the received signals return to normal. I seem to recall that someone else posted details of a similar such problem some time ago. Any suggestions would be helpful before I email the Elecraft hot line.
