Re: [Elecraft] (Elecraft) K2 Build #7552
Kevin, You have a K2 with the new encoder board. If the leads on that encoder board and the area of the Control board directly behind it are not flush trimmed (really, really flush trimmed), the two will make contact and 'strange things will happen'. Yes, the tools list does not include flush trimmers, but you will need them. Inexpensive flush trimmers can often be found in the electrical tools department of your local DIY store (at least here in the US Home Depot carries them) - look for Xcelite (or Lufkin or Cooper) 170M - it may be packaged with a pair of small needlenose pliers. Try putting some insulator between the encoder board and the control board to test and see if that cures the fault condition. There is not much clearance and you may not be able to put the screws in the control board while doing that test. 73, Don W3FPR On 9/27/2014 1:15 AM, Kevin Schache wrote: Hi to all, Firstly, let me introduce myself. I'm an 80 year old ham first licensed 1960, never very active on the bands, more of a builder than a contest DX-er, and even that building lapsed about 20 years ago until recently. it seems that building an Elecraft K2 had been on my to do list since it first appeared around the 1990s and now at last it's on it's way!!! K2 Build #7552 is proceeding nicely, even if somewhat slower than average. The Control Board and Front Panel Assembly completed and Alignment and Test Part 1 successfully completed up to 'Tap the PRE/ATTN switch three times'. (page 44). Now comes the first sign of a problem - no relay switching heard when I tap the PRE/ATTN switch. Ok, so now I'm off to check out that Front Panel board around that switch. I'd also like to say that I have been very impressed by the very professional nature of the kit and its manual. It was no small risk for someone of my age to outlay the necessary capital in the hope that I could manage the construction and I am finding huge satisfaction and enjoyment from the project. Well done Elecraft!!! 73, Kev VK5KS __ 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

Take a look at the K2 Auxiliary KPA100 Cooling Fan designed by Tom Hammond N0SS (SK). It is on his website maintained by the MMARC at http://www.mmccs.com/mmarc/n0ss/ Scroll down the opening page to K2 Specific Files, and then scroll down that page to the link to the pdf file. 73, Don W3FPR __ 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) Filter Set-up
After you've done what Bill suggested, try setting the loss (dB) for this filter, using the K3 Utility program. I believe the equivalent filter loss is 3-4 dB. This would be normal. The K3 can compensate for it, as long as you set the value (otherwise assumed to be 0 dB). Be sure the filter width and offset is set correctly. Easiest way is to use the K3 Utility program. 73, matt W6NIA On Fri, 26 Sep 2014 22:40:12 -0700, you wrote: Off the top of my head: It sounds like the signal isn't getting through the 250 Hz filter when you have it selected.

Re: [Elecraft] (K3) Filter Set-up
In addition to the other suggestions you have received (assuming still no signal through the filter), you may want to try the filter in another slot. Early on, I had the same problem after installing a 250 Hz filter. the problem ended up being a coupling cap on the circuit board with no solder on one end. I was able to find it, and touch it up myself. Mine was a fairly early unit (s/n 559).

Re: [Elecraft] New to me K3/10
Brian, Congrats on the K3/10. I am sure you will love it. Joe, W4TV, who is on this group will certainly answer any questions you have about the Digikeyer. For other pointers, it might help to read the manuals, in particular, consider buying the book by Fred Cady, KE7X: The Elecraft K3, Design, Configuration, and Operation which is available on the Elecraft web site or from Fred Cady's Lulu page. For other pointers, it would be easiest to ask specific questions. 73, phil, K7PEH On Sep 27, 2014, at 7:40 AM, Brian Short azbiblioph...@gmail.com wrote: I am the proud owner of a new (to me) K3/10 arriving Monday.

[Elecraft] Attempt #3 - Any larger more efficient heat sinks for the K2/100 Lid PA?
Sorry, my email GUI by default was sending emails in HTML which does not get processed by the reflector here. Thus why there was previously no information except for title in my previous posting attempts. Noob here. Here is my original email as I had composed it. -- I quit using my Elecraft K2/100 when I kept getting burned on the PAs heat sink. This is both before and after having sent it in to get a check up. I would like to place this radio in my emergency radio go box, but instead of adding fans which will just suck my batteries dry pre-maturely, is there a larger more efficient heat sink available for this amp (radio lid) which won't lead to too much macgyvering? Thanks for any assistance you may be able to provide in advance ! As a note, I'm using an external KAT100 and have always kept the match down. I always use mono band resonant antennas which I'm anal about tunning dead on and not operating into an antenna with a match anything more than a 1.5:1, and that's before connecting the KAT100 antenna tuner to it. Please, if anyone can provide me with a larger heat sink / solution to cool down this radio, I would be extremely grateful !

[Elecraft] PX3 Questions
I just received the PX3 kit. It was rather straight forward to assemble and to set up. I am learning how to operate the PX3. I have two questions. 1. Configuring the power switch, page 22. Pins 2 3: The PX3 turns on automatically when power is applied and may be turned off and off using the PWR switch as long as power is applied. I find that the PX3 does not automatically turn on when power is applied. I need to manually turn on the PX3 by pressing the PWR switch after power is supplied. Does anyone have a solution to this problem? 2. PX3 Utility. The capture screen function does not work. When I press the capture image button in the utility program, the PX3 freezes and the KX3A100 turns off. I have remove power from the PX3 and I have to reset the PA Mode in the KX3 menu back to on. Does anyone have any thoughts on this issue? Thank you.

Re: [Elecraft] Attempt #3 - Any larger more efficient heat sinks for the K2/100 Lid PA?
I've never had any such heat issues with my K2/100, Paul. I wonder if there's some other issue you need to address? Are you operating in a mode with a very high duty cycle (RTTY, PSK31) at more than 30 Watts or so? That could lead to higher than normal temps. 73, Phil w7ox On 9/27/14, 11:06 AM, Paul Metzger wrote: Sorry, my email GUI by default was sending emails in HTML which does not get processed by the reflector here.

[Elecraft] KAT3 ATU question
Question regarding the KAT3, internal ATU in K3. This is not clear to me in the product description. Does the KAT3 retune along with the VFO frequency, once memories are stored, without RF sent through it? Or, is Tune with transmit RF required for the ATU to sense the frequency and tune for best match? I believe the KAT500 adjusts based on rx frequency, but not sure about the KAT3.

Re: [Elecraft] KAT3 ATU question
The KAT3 doesn't recall LC settings just due to VFO rotation, although this is on the wish-list. The K3 will, however, send frequency commands to an attached KAT500 tuner as the VFO is moved. The KAT3 does recall LC settings when you use certain controls, including BAND UP/DN, FREQ ENT., MV (memory recall), VFO A/B SWAP, VFO REVerse, etc. Since the KAT3's relays are all driven at the same time (in parallel), transmitting in a different part of the band loads new LC settings so quickly that it doesn't interfere with CW element length. 73, Wayne N6KR On Sep 27, 2014, at 3:22 PM, John Sweeney n...@comcast.net wrote: Question regarding the KAT3, internal ATU in K3.

The K3 will, however, send frequency commands to an attached KAT500 tuner as the VFO is moved. The KAT3 does recall LC settings when you use certain controls, including BAND UP/DN, FREQ ENT., MV (memory recall), VFO A/B SWAP, VFO REVerse, etc. Since the KAT3's relays are all driven at the same time (in parallel), transmitting in a different part of the band loads new LC settings so quickly that it doesn't interfere with CW element length. 73, Wayne N6KR On Sep 27, 2014, at 3:22 PM, John Sweeney n...@comcast.net wrote: Question regarding the KAT3, internal ATU in K3. This is not clear to me in the product description. Does the KAT3 retune along with the VFO frequency, once memories are stored, without RF sent through it? Or, is Tune with transmit RF required for the ATU to sense the frequency and tune for best match? I believe the KAT500 adjusts based on rx frequency, but not sure about the KAT3.

[Elecraft] KAT500 Firmware Problem
From: KD3TB [mailto:idar...@gmail.com] Sent: Thursday, September 25, 2014 6:07 PM To: 'Elecraft Reflector' Subject: KAT500 Firmware Problem I had a problem when I installed the latest version of KAT500 Software (1.67) and not sure what happened? I had been operating for a few hours on RTTY and CW with my K3, KPA500 and KAT500 with the previous version of the KAT500 Firmware (1.63). After a while, I checked for new versions of firmware on the Elecraft site and downloaded the latest version of KAT500 Firmware (1.67) and installed. I also installed the latest version of K3 and P3 Firmware. At this point I could no longer find a tune point and even on Bypass was getting a high SWR? This was happening on antenna's that have a low (1:1.2) SWR. I then reinstalled the previous version 1.63. Disconnected all power to the KAT500 , after a few minutes, reconnected power to the KAT500 and turned the power back on. At this point everything was working fine..no problems. I am not sure what happened? Firmware did not install properly? Any suggestions?

[Elecraft] Elecraft CW Net Announcement
Good Evening, Like Phil, I have had a problem with posting net reports. As winter closes in I'll try to get them written more than irregularly. All of the information is in the pile of paper behind me. The sedimentary filing system threatens my ability to use the electronics bench. If I want to do any soldering I must clear a space. Strangely, my favorite part of amateur radio is building. Writing code for a variety of chips comes in second. Oregon has kept its weather promise. Dry and unseasonably warm switched suddenly to steady dripping interspersed with the roaring sound of falling water and cool temperatures. Cutting firewood in the 95% humidity is wet work. But, with the coming of autumn the sun has started to wake up again. SFU at 158 with a sunspot number of 203 bodes well for contacts tomorrow. Please join us tomorrow. 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7045 kHz at 0100z Monday (6 PM PDT Sunday) 73, Kevin.
