[Elecraft] Random problem in split mode.
Hello all, yesterday and today morning I saw a random problem with my K3 in SPLIT mode, time to time rig's PTT glues and keeps on TX until I strock my paddle, then it returns to RX. It happens only in SPLIT mode, since I never saw this problem previously during my activations. Best 73 and till next email.

Re: [Elecraft] Antistatic work mat
Hmmm ... before building my K3 (just finished), I bought a wrist strap and mat from Cables Unlimited at under $25 for both. Aside from cables that are a little too short, them seem fine So long as there is a wire with a 1-megohm resistor between a conductive mat surface and common ground, what is to distinguish a good mat from one that won't really provide the protection? 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com On 6/2/2010 6:22 PM, Bill Myers wrote: I'm about to order the K3.

[Elecraft] K2 VFO Linearization problem
I'm to the point of doing the VFO linearization. I went into Cal PLL with the test probe on TP1, my reading is 12098.8. I enter the Edit portion and the reading just sits there, never decreasing, never displaying d and never giving me an end message. I get no error codes either. Any ideas what I'm doing wrong? Unit checks great up to this point. Thanks for any help guys.

Re: [Elecraft] RFI PC Speaker Hum
All computer speakers are amplified. Many of them have very poor immunity to RF. I have sometimes reduced RFI to acceptable levels by winding a couple of turns of the cables through snap-on suppression toroids. Winding several turns through a large ring toroid would be more effective as the snap-on suppressors are really only designed to suppress VHF. Some computer speakers have such poor RFI immunity that they are probably beyond fixing. One pair I bought made by Logitech hummed even when placed near a cordless phone base unit that probably has an output power of a few milliwatts. The first time I pressed the PTT of my transceiver the resulting noise nearly gave me a heart attack. I gave them to a charity shop. There is a firm (I think it may be the one that makes RigBlaster interfaces) that advertises RFI-proof computer speakers, but I seem to recall the last time they were mentioned on this reflector they were out of stock. - Julian, G4ILO.

Re: [Elecraft] Antistatic work mat
Thu Jun 3 06:05:49 EDT Pete Smith (N4ZR) wrote ... ... what is to distinguish a good mat from one that won't really provide the protection? -- Hi Pete, A complete answer to your question will depend on the relative humidity and on the susceptibility to ESD damage of the devices being handled. FYI, the industry rates ESD sensitive devices into three classes based on their susceptibility to damage: o ESD Class 1 -- below 2,000 V o ESD Class 2 -- 2,000 V to 4,000 V o ESD Class 3 -- 4,000 V to 16,000 V o Not ESD Sensitive -- above 16,000 V Keep in mind that (WITH PROPER HANDLING) a sub-assembly may offer some protection to the individual devices that comprise it, such that the overall sub-assembly can withstand higher discharge voltages than the most sensitive components that comprise it. This makes perfect sense since the highest level assembly, i.e. a completed K3, is (generally) not ESD sensitive! --- - - - --- I also mentioned relative humidity in my opening sentence. FYI, at the aerospace manufacturing facility (where I worked for ten years) even our good mats were only adequate when the relative humidity was above 30%. Below 30% RH air ionizers were also required at ESD work stations. These devices aren't something you'll want to consider as they cost upwards of $500! Oh, and they only protect a very small area, i.e. just a couple square feet of work surface at most. That said, perhaps Elecraft would consider using them in Aptos as an additional layer of protection? --- - - - --- In light of the above details, the best answer I can offer is that there is an industry specification for the surface resistance of an ESD mat, which is specified in the unusual unit Ohms per square.

Re: [Elecraft] K3 - I wonder
This could very easily be a nice K3 Utility feature. Actually, a good model for this feature is found in MS Visual Studio 2010 (and, earlier versions).

Re: [Elecraft] K3 - I wonder
Wayne and David and I have made dramatic improvements to the speed of configuration save and restore in upcoming K3 Utility versions (that depend on recent MCU versions). It will take on the order of 5 seconds to save and 10 seconds to restore a configuration (once you've selected the configuration file), and half of that is the MCU reset after restore. Not every K3 front panel key press is currently available for an undo stack. In particular, when I enter a menu and change a parameter, nothing is sent to the PC host to alert it to a configuration change. Few of us (including me) would be willing to keep a program like the K3 Utility connected to the radio during all radio operation to support an undo stack. During contests, my contest logging program controls the radio. At other times it might be connected to a DX logging program. Yes, I use Visual Studio. I'm stuck at VS 2005 because that's the last version that compiles code that will run on Windows 98 SE / ME. Phil, you should be aware that the Microsoft Visual Studio Program Management / Development / Test / Customer Support team is a tad larger than the K3 Utility, P3 Utility, K144XV Utility, W2 Utility, K3 Voice, and K3 Frequency Memory Editor team. And there are cost/revenue issues. Visual Studio's features must be whiz-bang to gather developer hearts and minds so that applications will be written for Windows. Not too many chose the Elecraft K3 over its competitors because of a feature-rich K3 Utility. The K3 Utility needs to do a few jobs reliably. If it were terrible, it could hurt customer satisfaction with the K3. It must be simple to use so that occasional users can get firmware loaded with a minimum of fuss. I use Visual Studio all the time. It's a pretty feature rich environment. And the learning curve was non-trivial. Elecraft sells amateur radio equipment. The K3 Utility is offered to customers without additional charge. It's a necessary adjunct to enable customers to update the radio's firmware. The K3 Utility is not a revenue source for Elecraft. Visual Studio (even with free Express editions) is most certainly a revenue source for Microsoft. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil Hystad Sent: Thursday, June 03, 2010 6:47 AM To: Hector Padron Cc: elecraft@mailman.qth.net; Jim Miller KG0KP Subject: Re: [Elecraft] K3 - I wonder This could very easily be a nice K3 Utility feature.

It could be the perfect size for a homebrewed matching power supply and/or speaker, etc. --Andrew NV1B __ 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
[Elecraft] K3 won't TX in USB??
Hello, I can not get my K3 to transmit in Upper Sideband. Operation is fine when in the CW and LSB modes. However, when I go to USB, regardless of band, I seem to have no microphone gain or RF output. The K3 was functioning fine a couple of days ago, I assume that I fat-fingered one of the functions! Can anybody help me?

Re: [Elecraft] K3 won't TX in USB??
Tom, Check to see that you have a transmit filter selected for USB. I STILL don't know how I fat-fingered that one, but did it to myself once (LSB actually). 73, Don, WB5HAK __ 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
Re: [Elecraft] Suggestion: Sell P3 matching enclosure
I would echo Andrew's request. Althought I know you have said there is adequate room in the P3 enclosure for a homebrewed power supply, I have several things I would like to build into an enclosure matching the K3. I would buy one (or two) today 73.

[Elecraft] XV50 cooling
I have a late-model xv144 with holes in both top and bottom panels, connected to k3 with milliwatt drive. It runs excessively hot at 10w out in digital mode EME when used one minute on one minute off, so i dont think just getting new panels will help you. I use a small muffin fan blowing air underneath with the xv-144 up on the optional tilt stand and this simple solution works great. I also use an xv-432 for eme at 10w but its internal fan keeps it cool. Perhaps if enough people request a retrofit kit with an internal fan for the xv-50 and xv-144 Elecraft would consider it. I'd pony up. The fan could attach inside the top panel. 73 Eric WD6DBM Sent from my ePhone (I wish) __ 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
[Elecraft] K3 with Heil HC-5
I've settled down on the HC-5 as the best sounding SSB TX audio. It was after spending the time to determine that this was the right answer for the K3. The TX equalizer should be tailored based on your own voice to give it the best fidelity. Because of my great audio, I get asked what mic I'm using on many occasions.

[Elecraft] K3 Mods
Hello Everyone, Yesterday, I did the following mods for my K3 #384, running FW 3.99: K3DSPUPGD K3 Negative ALC and External Band Data Pull-up Mod Front Panel Mike Circuit Mod IF Buffer Gain Mod. I was scrupulous about ESD precautions, using a wrist strap and anti-static mat. Before the mods, everything worked perfectly. After the mods, receive seems OK, audio is improved, but I have some problems on transmit: 1) Attempting to transmit RTTY with MMTTY now produces no RF output from the K3. I use AFSK A for RTTY. It seems like I have no T/R switching. Tune, CW and SSB work correctly and produce the expected output levels. 2) The K3 does not key up my ACOM 1000 amp on Tune or CW. It keys the amp OK on SSB when the PTT button on the mike is pressed. It also keys the amp OK in CW mode if the mike PTT button is held down. I checked that VOX is enabled for CW. RTTY produces no output from the amp under any circumstances. I have reloaded FW 3.99, and then went back to version 3.97 (all files), but the problems remain. I have checked and rechecked and rechecked all cable connections to the K3 back panel, as well as my CONFIG and MMTTY settings. Everything looks OK, but I may have missed something. BTW, I don't use ALC with the amp. To summarize the problems: 1) The K3 produces no output in RTTY 2) The Key Out jack (for keying the amp) does not function with VOX. Any ideas?

Re: [Elecraft] XV50 cooling
Eric, Have you actually measured the temperature rise? I am interested in just how much is excessively hot. While it does get warm, I have always found the temperatures to be well within spec for the output module. I have an XV50 here for repair right now. It is next in line for work, and I intend to get to it this weekend. After it is repaired, I will measure the temperature rise on the bottom panel right under the heat spreader. I have a Fluke 279 with a temperature probe available.

Re: [Elecraft] K3 Mods
Hi Wes, Good thought! I will check this out tomorrow. Maybe the new DSP audio daughter-board affects the sensitivity of the VOX. If, not, I'm just hopeful that someone has seen these symptoms before and found a solution. Otherwise, I will need to take the rig all apart on Saturday to check that everything is plugged in correctly. I'm pretty sure that it will be a waste of time, because I am a very careful and experienced builder. I carefully checked the pins on the various boards and connectors as I plugged them in.

Re: [Elecraft] K3 Mods
As I write I'm camped on 14.080 trying to work E4X on RTTY. My K3 is set to mark=915. I just set MMTTY to 2125 and I get full power on transmit. Remember there was a VOX trip problem too. That should not be affected by the mark freq. It will however, as I wrote to John earlier, be affected by the Line In (Mic) gain setting.

[Elecraft] Re: XV50 cooling
Hello Don, The situation is - after I operate either XV144 or XV50 for a 10-15 minutes QSO under 10w FM or 20 w SSB (the advertised rated output from Elecraft, p.3 of the owner's manual), the bottom plate (or even one of side panels) is too hot to be touched. I would be very interested in your findings and fully appreciate your knowledge of Elecraft products. After your test, I would be grateful if you could advise, it is all ok to operate the XV50 / XV144 under Elecraft's rated output WITHOUT the need of any modifications to remedy the heat issues. It would be of great assistance if you could give your advice about the maximum length of any QSO under the rated output. In other words, say for example, I should not use the XV50 / XV144 for any QSO longer than 15 minutes.

Re: [Elecraft] Re: XV50 cooling
Johnny, Be confident that I will test at the 10 watt level (simulated FM) for a significant length of time, and also Eric's situation - 10 watts, 1 minute on, 1 minute off. I did similar stress testing on both large and small devices for the last 10 years of my professional career - I am quite familiar with the procedures required to test to specification - unfortunately, I do not have an environmental chamber available anymore to conduct the test at the highest ambient temperature allowed for the assembly, we will have to settle for a temperature rise measurement and extrapolate from there. If the temperature goes above the power module's spec, I will terminate the test early (I don't want to produce a failure in someone else's transverter), but will attempt to run for your suggested period of time if the temperature stays within spec. Elecraft rates the transverters at 10 watts continuous duty and 20 watts intermittent, the output module is rated at 30 watts ICAS by the manufacturer, so Elecraft's rating should be conservative. This XV50 does have the vent holes on the bottom panel. While it is nice to keep things cool, sometimes the device manufacturer expects things to get too hot to touch comfortably. Despite my thoughts that it may be hotter than desirable, I have to have faith that the device manufacturer has done sufficient testing to substantiate his specifications - users should hold the manufacturer's feet to the fire if that is not true. We will see. 73, Don W3FPR Johnny Siu wrote: Hello Don, The situation is - after I operate either XV144 or XV50 for a 10-15 minutes QSO under 10w FM or 20 w SSB (the advertised rated output from Elecraft, p.3 of the owner's manual), the bottom plate (or even one of side panels) is too hot to be touched.

Re: [Elecraft] XV50 cooling
Evening gang: Just got home from work and reading my male.I looked at the manual for the XV432 to see how the internal fan is mounted and how it was hooked up. It really doesn't look like much of a task to modify my XV50 and install such a fan. I contacted sales and was told the vented panels are not available. As much as I hate drilling my own panels ( don't like messing up the paint ) I see very little challenge in copying what Elecraft did with the 432 version. I will wait Don, to hear the results of your tests before doing anything. 73 to all; Jerry N0JRN On 6/3/2010 1:18:45 PM, Eric (gliderboy1...@yahoo.com) wrote: I have a late-model xv144 with holes in both top and bottom panels, connected to k3 with milliwatt drive.

Re: [Elecraft] Re: XV50 cooling
Johnny, Prior to testing, I have reviewed the datasheet for the RA30H0608M module that is used in the XV50. The power module is specified to operate within spec at 110 degrees C ( 230 deg F). While that is too hot to touch (in excess of boiling water temperatures), it is well within the device specifications. I am looking at the Mitsubishi data sheet for the RA30H0608M device. I will see what my tests reveal, but I believe the answer will be that the temperature is well within the device specifications. The MTBF for the device is not specified in the datasheet, but it ia a well known fact that the MTBF for any device decreases with the operating temperature. So the early answer is that the output module will likely operate within its specified temperature range, its longevity might be extended by providing extra cooling to reduce its operating temperature. Testing will reveal the actual temperature rise - details later. 73, Don W3FPR Johnny Siu wrote: Hello Don, The situation is - after I operate either XV144 or XV50 for a 10-15 minutes QSO under 10w FM or 20 w SSB (the advertised rated output from Elecraft, p.3 of the owner's manual), the bottom plate (or even one of side panels) is too hot to be touched.

Re: [Elecraft] K2/100 Has No Output on 80 or 40 When Hot
Hi Don, Thank you for your help and information! K15 was the offender - when hot, pins 3 to 4 and also 7 to 8 stay connected after changing the band from 20m down to 40 or 80. This cuts off the path through K14 and K13 to C71 and C72. 73, Phil W6TQG -Original Message- From: Don Wilhelm [mailto:w3...@embarqmail.com] Sent: Wednesday, June 02, 2010 5:50 PM To: Phil-W6TQG Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K2/100 Has No Output on 80 or 40 When Hot Phil, The problem will be found in the VFO Range Selection area. Look at the schematic for the RF Board sheet 1. Check the soldering of C71 and C72 and relay K13. It is possible that when hot, the contacts of K13 (and possibly K14) are not making good contact. Set to 80 meters and wait until the failure occurs, then power the K2 off and quickly (before things cool), check for continuity between K13 pins 3 and 4 also between pins 7 and 8 - both should be zero ohms - if not, the relay has failed. Check K14 in a similar manner, but set to 40 meters - after the failure, you should have continuity between pins 3 and 4 of K14 and also between pins 7 and 8. The relay pins are numbered like an IC (pins 1 and 10 are at the same end). Look for the round solder pad at pin 1 (or the end with the white stripe). This is either a temperature related solder connection or a relay contact problem. 73, Don W3FPR Phil-W6TQG wrote: Hi Don, Thank you for your help. Yes, it appears to be the VFO. The VCO readings at TP1 for 20, 30, 40 and 80m are normal when the K2 is cool, but when hot the readings are near 15,600 for 40 and 17,257 for 80.

A total lack of power (yes, a display of 0.1 or 0.2 watts is actually no power out) is most likely a problem either in the bandpass filter or a problem with the VFO. Try the VFO first - set the frequency to the low end of the band and check the frequency with the counter probe in TP1 using CAL FCTR - compare your frequency reading with the chart on the Schematic Key page. If you want to calculate the proper VFO frequency it should be within a few kHz of the frequency on the dial plus 4915 for bands below 15 meters. Check all the components in the bandpass filter area for 40m and for 80 meters. On 40 meters, be certain C6 is properly installed between the two outer holes of the J15 position (the center hole should be empty). 73, Don W3FPR Phil-W6TQG wrote: Every since the last Field Day, my K2/100 (#3713) loses output, and the receiver goes dead, on 40m and 80m when it gets hot. This occurs for power levels of 9 watts and 100 watts. The 30m through 10m bands are OK. I can easily replicate the problem when the power amp is connected, but so far it seems to be OK when it is completely unplugged from the K2. Turning off the power amplifier through the Secondary Menu does not make a difference. While transmitting at 9W, the readings on the display for 40 and 80 are 0.1 1.01 - 1. With the power amplifier connected to the K2, I temporarily connected the antenna to J4 on the K2, so that I could bypass the power amplifier path. This did not help the dead reception on 40 or 80. I also tried connecting a dummy load through a power meter to J4 and transmitting at 9W. Again 40 and 80 didn't work but the higher bands were OK. I am assuming that the problem is in the LPF of the power amplifier, but am not sure 30m is OK, while 40 and 80 are not.

Re: [Elecraft] XV50 cooling
Well, as I recall I could not hold my hand on it, but i only ran it without a fan once when I first built it and my memory is hazy. Remember digital EME is one minute on, one minute off for hours. I have run four hours at a time that way without a break, and I'm sure others run longer. Maybe it was still in spec, but why push it? All that extra heat can't possibly make the XV more stable or less prone to failure than if it were running at room temp. Mine does have the xtal oven if that makes a difference. I don't know how much heat that adds to the system. 73, Eric WD6DBM Sent from my iPhone On Jun 3, 2010, at 4:18 PM, Don Wilhelm w3...@embarqmail.com wrote: Eric, Have you actually measured the temperature rise?

Re: [Elecraft] Re: XV50 cooling
Don, some other considerations: 1). What about the other components inside the XV? If the power module is happy running at 100C what does that do for everything else in the XV running at 60-70C with no airflow? 2). My ambient temp in the shack during EME is 80F even with the house A/C running due to the tube PA. 3). Does the XV144 run at the same efficiency (waste heat output) as the XV50? Thanks for your assistance. I look forward to your measurements. 73 Eric WD6DBM Sent from my iPhone On Jun 3, 2010, at 9:02 PM, Don Wilhelm d...@w3fpr.com wrote: Johnny, Prior to testing, I have reviewed the datasheet for the RA30H0608M module that is used in the XV50.
