Re: [Elecraft] (K3) loose front panel microphone jack
Gary, The shell of the microphone jack will normally rotate slightly, this is not a problem. If you notice carefully, you will find that the pins are not loose, it is only the shell that moves. It is due to the way the jack is made. Since Elecraft solders the mic jack pins to the board, but does not mechanically fasten the shell to the front panel metalwork, this condition becomes apparent. Should you want to fix it, you can remove the left side panel, scrape away a bit of the solder masking right at the base of the mic jack shell and solder the shell to the exposed copper ground plane. It takes quite a bit of heat because both the mic jack shell and the ground plane will suck heat from the iron, so use a large tip on the soldering iron for best results. The mic jack shell is already grounded with a wire wrapped around it, so the soldering I mentioned above is only to keep the shell of the mic jack from rotating - in other words, it is entirely unnecessary. The loose washer problem that you refer to is on the headphone jack. 73, Don W3FPR On 7/11/2014 12:11 AM, Gary K9GS wrote: Hello all, I noticed right before FD that my K3 front microphone jack is loose. I'm aware of the washer problem but think that was in earlier K3s. My K3 is ~ S/N 5400. So, two questions: 1) How difficult is it to get to the mounting nut to tighten? Is this a 1/2 hour job or are we talking about setting aside a couple of hours? Any helpful hints? 2) Any hints on how to prevent this from happening in the future? Lock-tite?? Is there a recommended torque spec the factory uses? I rarely operate phone and when I do I usually use the rear jacks.

Re: [Elecraft] OT: Butane soldering irons
On most of those irons there is a control to adjust how much air gets into the mixture. On all that I have used you can change this to compinsate for altitude.

Re: [Elecraft] [KX3] Effectiveness of CW decode functionality
Try turning the R.F. gain down. This might help. Sent from my iPhone this time On Jul 10, 2014, at 11:10 AM, Gary Hawkins g...@hawkins-zhu.com wrote: I tried out the CW decode functionality on the KX3 for several evenings and I'm struggling to get very positive results. Basically, unless the received CW signal is peaking close to s9 and the noise is s1 or less then decoding seems unreliable. If the signal drops towards the noise then everything just falls apart. I've tried various settings of threshold, pre amp On/Off, RX bandwidth etc., but I'm struggling to get successful results. Can anyone tell me what to expect in terms of performance, and what might be the ideal settings for best reception? The reason I've been trying this is because I've paired my KX3 with KX3 Companion, a Samsung Tab 3 8.0, an OGT cable, plus the data cable that came with the KX3. I've been able to remotely control many features of the radio, send CW and use up to 20 canned message macros, as well as direct input from the keyboard. KX3 Companion also has a logging capability and polls required information from the rig (freq, time, mode). While the KX3 Companion is not 100% perfect yet, with a little more development it could be a very powerful add-on to the radio. If you're interested in this sort of thing I would definitely give it a try. Please note the KX Companion required USB Hosting on the mobile device - the Samsung Tab 3 7.0 does not support this. The Tab 3 8.0 and 10.1 do. 73's Gary K6YOA __ 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 gerrylear...@icloud.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] OT: Butane soldering irons
That has nothing to do with flame from the stove. Water boils at a lower temp at altitude, so you have to cook things longer in boiling water. At 7400 ft ASL, the boiling point of water is 198.5 F. Barry W2UP Re: I couldn't ignite it. It would sputter and refuse to burn. We were at 7400' (2260 m). That doesn't surprise me. I don't have experience with butane torches at altitude, but I have eaten far too many freeze dried dinners that were crunchy because, at altitude (8,500 ft. in my case), there wasn't enough oxygen in the air so that the flame from my friend's butane stove would heat the water hot enough to reconstitute the food. Cold temperatures affect butane stoves as well. Put high altitude together with cold temperatures and the result is crunchy noodles! (My old Svea white gas stove works well to 11,000 ft., even in the cold, but it has its own hazards).

Decided it was not worth the hassle. Therefore, if I want a larger screen for the P3 then I would use an SVGA monitor that could be bought for $50 to $150 depending on lots of variables. But, if you want full rig control (logging at least) on a Mac then the there are a handful of products that do that but they do not include panadapter features (as far as I know). As someone has suggested, you could possible use a frame grabber which would take the SVGA output of the P3/SVGA and then display the results with a suitable app on your mac but that seems to be going way overboard and I am betting with less than excellent results. Fast real-time response on the P3 screen may be difficult with a frame grabber approach. I think there could be a great market (although likely free software) for a good Mac interface to a K3 or KX3 that is akin to something like the Flex Radio PC software. This would require something different then a P3, the LP-Pan type solution instead of a P3, but the KX3 could interface directly with its I/Q output. 73, phil, K7PEH On Jul 10, 2014, at 4:14 PM, tom armour wa...@hotmail.com wrote: Why not just look at the P3 display?

Re: [Elecraft] PA with predistortion
Predistorsion properties are impressive. The following presentation http://users.burlingtontelecom.net/~n1...@burlingtontelecom.net/images/Eastern_VHF_UHF_Conf_2014.pdf gives some information what is possible. In LDMOS amp with bias almost reduced to 0, IMD3/5 change from -22/-28db to -55/-63db. Also a crappy 13.8V CB amp with IMD3/5 of -18/-28 becomes -47/-53 after predistortion. Class AB amps have an efficiency of around 50%. B class amps (also in drivers) perhaps can raise it to 70%. 40% less input current and 55% less dissipation, all at excellent IMD. All for nothing, oops, for lots of programming if DSP is powerful enough. Perhaps in 10 years nearly all new rigs will have predistortion implemented. Probably K3/KX3 do not have powerful enough DSP to do it. For example, the biggest limit in KX3 on SSB is speech processor that is currently just a treble boost. 6db lost. The fact that it is not done means that it cannot be done easily.

I skimmed the presentation. There are no surprises. Several thoughts. First, this is pretty complex -- that feedback (sense) loop from the amplifier output is critical. Why not simply buy a cleaner rig and amp, and run them under conditions that make it cleaner? Study the presentation that K6XX and I did for NCCC last fall. The measures that Bob talks about are very easy to implement. http://audiosystemsgroup.com/K6XXAmpTalk.pdf A decent tube amp, carefully tuned, is about as clean as the results of predistortion, and is a lot simpler. Also, it seems to ignore phase noise, which is produced by the rig. It also ignores sidebands produced by distortion that results from overdriving audio stages. FWIW, I see no reason for Elecraft to support it other than possibly for their own power amps. I suspect Wayne has looked at it. 73, Jim K9YC __ 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

NOTES: (1) In voice modes (using the built-in DVR), only messages 1 and 2 are available, corresponding to BAND+ and BAND- in fast-play. (2) At present, message chaining is only available in CW modes (with both normal and fast-play). • MORE ACCUTATE KXPA100 “TUNE” POWER OUTPUT (PA ALC FEATURE): More accurate control of the KXPA100’s power output during TUNE from the KX3. This applies to settings from 11 to 70 W (60 W on 6 meters). Above this point, KXPA100 drive is still estimated based on the 75-W factory calibration. This prevents accidental overdrive in conditions sometimes found during full-power portable or mobile operation, such as high SWR, high current, etc. NOTES: (1) PA ALC is enabled by default. To disable PA ALC, locate MENU:PA MODE, then tap ‘1’ (PRE) until you see “PA ALC-”. (2) PA ALC only applies during TUNE, not during normal transmit. Also, if you change bands or adjust PWR, and want to fine-tune the KXPA100’s power output again, you’ll need to do another TUNE. (3) PA ALC does not apply if TUN PWR is in effect, since the TUN PWR limit is 10 W, bypassing the amp. • KXPA100 TRANSIENT FAULT DISPLAY: Common KXPA100 faults requiring operator notification, such as high SWR, are always reported on the KX3’s display. Transient faults such as serial port errors are normally not displayed, since they rarely impact operation. For diagnostic purposes, such faults can now be displayed as “FAULT nnn” where nnn is a 3-digit number originating from the KXPA100. To enable this mode, go into the KX3’s PA MODE menu entry and tap ‘6’ (DLY) until you see “XFAULT+”. • FULL SUPPORT FOR PX3 PANADAPTER. • 40-METER TRANSMIT BUG FIX: The 40-m band-pass filter was being bypassed in transmit mode, due to a change in rev. 1.94 that allowed MARS operation from 8.5-9 MHz. This resulted in an increase in the amplitude of some narrowband 40-meter transmit images, most notably in FSK-D mode. (The low-pass filter setting was correct, though, which made this error hard to detect. Wideband spurious suppression specs were met.) __ 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] My KX3 Battery Approach
I looked there. it appears to hold 8 cells, not ten. Plus ships from Hong Kong, so a bit of a wait :-) The 10-cell holders seem a bit hard to find. In fact, I'd looked and not found one -- so I was quite surprised to see one in my local store and grabbed it. My old standby is a 10 AA holder which came with an old Icom 02-AT!

Re: [Elecraft] My KX3 Battery Approach
You can find the 10-cell on ebay. It does come from China and takes a few weeks. But they're cheap. 72, Doug -- K0DXV On 7/11/2014 6:11 PM, Phil Wheeler wrote: I looked there. it appears to hold 8 cells, not ten.
