[Elecraft] UK Elecraft Net
Hi all, I will be running the Elecraft net as usual on 3658 +/- QRM at 09:00z tomorrow (12/12/10). I have had various questions regarding frequency and time changes. We have tried 40m in an attempt to see if we could cover more of Europe but unfortunately at that time, it is almost impossible to hear inter-G activity. As for time, 09:00 is the time I have available to run the net. Signals are also quite good at that time now. If anyone wants to run a 40m net at another time, feel free :) That said, if you have a K2 or K3 and you have some time tomorrow morning between 09:00 and 10:00z, I would be very happy to hear you! 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC HB9DRV-9 DX Clusters Member RSGB, GQRP 9838, FISTS 14077 | K3 #455 http://www.m0scg.org.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

[Elecraft] unusual problem
Recently, I started noticing a strange sound from my K3-4290. When keying the rig on CW I'll hear a crackling or almost a gurgling sound coming from the radio itself. It's only happened 2 or at most 3 times but this morning I smelled something for the first time. It started happening right after I upgraded the firmware although I doubt there's a connection. I'm guessing a coil could be arcing, although as a person who is blind, I'm afraid I can't offer any visual data. Any thoughts?

Re: [Elecraft] unusual problem
Sam, Not sure which accessory is the KXV3a. I do have the internal tuner and a G5RV and a tribander hooked to the A and B antenna jacks. I have no amp and use the G5RV most of the time. I should also mention that everytime this has happened, it's been right after turning the rig on after it has been sitting overnight in a chilly shack. It'll arc for a few seconds, only while transmitting, and then settle down. So far, I haven't noticed any other anomales in the operation of the rig.

I had the KXV3A in mine and added an antenna to the RX ANT IN Then I transmitted on another antenna. Everything was fine when running 100w. Then I turned on my Ameritron AL-811 amp. When I transmitted I heard a sizzling sound, and smelled something burning. It turns out my RX antenna was to close to my TX antenna. The result was the GAP 1 melted the solder holding it. It then dropped on the top of the relays on the KXVA3 board. Since the GAP 1 is ceramic, the heat from it melted the plastic case on the relays, causing the burnt electronics smell. The rig continued to work, but the RX antenna no longer worked. Perhaps this is your problem?

Re: [Elecraft] An AGC story
Chen, It is not really my place to comment on this subject not having a K3 to measure, but I would like to offer the following thoughts related to the naughty things you mention. Whereas measuring the receiver's audio output level vs.the level of a single signal injected into the antenna input port will obviously provide some good information about the AGC's control characteristics, unfortunately this measurement does not provide any hard data as to whether or not intermodulation generated in the IF stages will become or is an issue when two or more strong signals get through the roofer in use. Given that the 1db compression point of a typical SA612 mixer is reached when the *composite* power of all signals reaching its input is approximately minus 25dbm, and given that positive gain exists between the antenna port and the SA612's input when both the Preamp and Attenuator are OFF, in the region of 6db I believe when a 400 Hz roofer is in place, then in the *absence* of any HAGC action the SA612 would enter compression when the *composite* power of all signals at the antenna port that eventually get through the roofer is only minus 31dbm. At this level *without* HAGC applied there would be, of course, a large number of of strong odd order intermod products appearing at the SA612's output should multiple signals get through the roofer. Now bring in the HAGC. Because part of the method used to control IF gain by the HAGC involves current starvation of the J309 IF amplifier, it is *possible* that with HAGC applied the Output Intercept (OIP3) of this amplifier might decrease, thereby increasing the level of IMD products generated by this amplifier. So, even though the HAGC might prevent the SA612 from approaching compression, much of the HAGC's protective work in terms of reducing unwanted IMD products *might* be undone by the J309 when it is starved of current. Please understand that this is pure speculation on my part. If I had a K3, before I changed the HAGC threshold my *first* measurement would be to look at the output of the SA612 mixer (with a spectrum analyser) while introducing two or more very close spaced signals into the antenna port, so that these signals do get through the roofer - as in a pileup. The objective, of course, would be to obtain an acceptably clean output from the mixer with non intrusive products over a wide range of antenna input levels. IMHO the higher the HAGC's threshold can be the better, provided that its control is tight enough when activated to protect all what follows. 73, Geoff GM4ESD Kok Chen wrote on Thursday, December 09, 2010, at 7:05 PM: We know that the S9+ signals have to be kept from saturating the A/D converter (or even kept in check so the large signal doesn't do naughty things to the IF amplifier and the SA612 second mixer -- I don't know which of these three is the wimpiest in the chain).

[Elecraft] XG1
G'day, A cautionary tale. I decided to check the total receive signal loss through my system from the coax termination in the wall to the K3, via the amp and antenna switching having had a hot switching event. I first plugged the XG1 directly into the K3 and with the agc off set the dBV reading to 0.0 with 50uV. Next moved the XG1 right to the end of the last internal coax cable. -1.7dBV! Whilst moving the XG1 I noticed that the reading returned to the set point 0.0 dBV when I picked it up. I turned out that placing the XG1 on its rubber feet on a metallic surface (the case of the linear) resulted in this signal loss. Holding the XG1 in the air by the cable that connected it to the K3 removed this loss. I didn't check the effect of placing it on the wooden desk surface. When connected to the K3 I simply use a BNC to PL259 adapter and it sticks out the back self supported. Just an observation.

[Elecraft] Raves about the K3
This is my first post to this reflector and would like to share some of my observations. First. I have a 4xxx series K3, built by Elecraft that is fully outfitted and filtered running LP-Pan, an EMU-0202 and a MicroHam Station Master. Second, I have been operating an IC-7700 for the past 2 yrs. That being said I have run both rigs side-by-side into a IC-PW1 and Palstar AT-Auto. I must say that each radio has its own benefits and is outstanding to operate, but here is where the K3 shines: 1. True dual VFO/dual receive; 2. Easy MARS modification (yes, I am a licensed AF MARS Operator); 3. IF out. LP-Pan and PowerSDR are outstanding; 4. ESSB - of course with the proper filtering being installed; 5. Tx Eq and Noise Gate - No out-board W2IHY EQ is needed (sorry Julius); 6. Light weight; 7. Unbelievable receive audio with the appropriate filtering; 8. Menu flexibility;and 9. Easy updating of firmware. Candidly, I still love and use the IC-7700, but more and more I am utilizing the K3. The K3 is an outstanding value and robust transceiver. As a separate matter (a bit of a rant here), and for example having seen the ARRL and Sherwood engineering reports regarding the FTDX-5000. We as hams are always in search of nirvana. While I have heard the issues regarding the FTDX-5000 design that have not made the mainstream press, the issue here is not to bash Yaesu, but to congratulate and thank Wayne and Eric for the OUTSTANDING job, not only with the design and operation of the K3, but their support of the user group to identify issues and improvements and their outstanding customer support when you call them for assistance. Kudos to Elecraft.

[Elecraft] K3: Voice Fast Monitor
As the person, or one of them, who asked for the Voice Tx Fast Monitor facility which has been included in V.4.22, can I say 'thanks' to Wayne Lyle for this new feature? It allows sidetone monitoring of transmitted audio without the somewhat disconcerting delay, albeit without hearing any compression. If you want to hear the level of compression, a touch of one of the mic controls while you are transmitting changes the sidetone over to monitoring the true transmitted audio. Also the APF is going to be great for pulling out those weak topband signals. All I need now is a fix so the K3 will operate at temperatures below 15C, then I can get rid of the 100 watt tubular heater which burns continually underneath it! 73 Tom G3OLB __ 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] K144XV Manual (corrected)
TRN0 identifies the transverter as being the internal unit that switches crystals. From the K144XV manual: 2) Setting ADR to Int. Trn0 tells the K3 the internal 2 meter module is being used rather than an external transceiver. This sets up the KXV3A correctly and enables automatic K144XV crystal switching at the146 MHz boundary. Any value from Int. Trn0 through Int. Trn9 may be used, but Int. Trn0 is the default for 144 MHz operation. Int. Trn1 through Int. Trn9 provide unique band data signals at the KRX3 output that may be used to control external higher-frequency transverters connected to the K144XV. See Band Data in the K3 Owner's manual for details about the data signals. At one time, TRN1 was used for this, but it the firmware was changed last September and the manual was updated accordingly.

Re: [Elecraft] W2 Bug
Jacques, Is it possible that you have accidentally put the W2 into the auto-sensor mode that monitors BOTH S1 and S2? That is one reason the S1/S2 lights blink alternately. I use my W2 in an SO2R station and I prefer it this way but if you are using a single sensor, it will not give you the result you want. Also, I had a lightning strike at my station and saw VERY sporadic readings from the W2 before I replaced the sensors. Once I replaced the sensors and the W2, everything worked as expected. Is it possible you had a lightning surge? Good luck figuring it out. Mine is working very well and I am happy with it.

Re: [Elecraft] Noise Blanker Problems
Not here Geoff, but I can't really tell. I assume there will be distortion any time one goes whacking great holes in the spectrum of a signal to blank noise pulses, and that will vary widely based on the strength of the signal, presence of nearby signals and many other factors.

Re: [Elecraft] An AGC story
Hi John, The NPR test is, I agree, certainly a very useful method to expose IMD problems, but I think that when used as a *diagnostic* tool the requirements placed on the notch filter's bandwidth limits this method's versatility - unless one is prepared to build a set of band reject filters (probably crystal) that may be required, whose IMD contribution is much less that that of the receiver, device or sub-system being tested. To obtain low phase noise from my IMD test arrangement I have been using low noise crystal oscillators followed by +40dbm output amplifiers, which is I admit a cumbersome approach, but it did provide useful results until I damaged the equipment while measuring the IMD generated by some types of RF transformer - a sad story! If Santa gave me a K3 I could stop speculating about its multi signal performance :-) 73, Geoff GM4ESD juergen plebia...@yahoo.com wrote on Saturday, December 11, 2010, at 6:18 PM: Hi Geoff The noise power ratio test(NPR) might show more clearly any mixer IMD problems.

[Elecraft] Audio mixer request: A - A and B - B
Hello, I have noticed that the CONFIG:L-MIX-R configuration setting currently has six options: A - B A - AB AB - B AB - AB A - B A - AB The keen reader will notice that option 5 equals option 1, and option 6 equals option 2. This is probably a (cosmetic) bug. Instead of correcting this flaw by removing options 5 and 6, I would love to have the following settings for options 5 and 6: A - A B - B This would enable me to implement an elegant AutoHotHey mono/stereo toggle for my SO2V K3 (people doing SO2R with N1MM may know the mono/stereo toggle as that what happens when you push the back-quote (`) key). (Currently, I must use an ugly workaround in my AutoHotKey script in order to achieve the mono/stereo toggle: in mono mode, I set CONFIG:L-MIX-R= AB - AB and then set the RF gain of the receiver that must be muted to 0 and the other RF gain to max. While this does work, using the script I cannot use the RF gain front panel controls in their intended manner, thus reducing the number of options that I have to combat strong signals at the upper range of the K3's dynamic range...) 73, Frank PA4N __ 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] Yamaha CM500 and ANTIVOX setting
I decided to try the CM500 headset in place of the Elecraft Heil Proset headset. I'm always on a quest for increased volume due to age related decreased hearing. To that end I can emphatically say that the CM500 solves my low audio level problem. The CM500 in the rear headphone jack provides greater audio output then the Proset in the rear speaker jack. So far, so good. I tried the CM500 on SSB today in the 10 meter contest and had occasional VOX tripping when listening to loud signals or loud noise. I'm using the headphones and there is no speaker output. (I even held my breath to be sure my breathing wasn't tripping the VOX). I reduced the VOX GAIN to 17. Any lower and I couldn't always trip it reliably. My ANTIVOX was set at 20 for the Proset so I began to crank it up. It's up to 80 now for the CM500 and appears to have solved the problem. My other settings are: RP.L BIAS MIC GAIN = 10 for 5 to 7 ALC bars Comp = 20 for 10db CMP Has anyone else experienced this problem? 73, Mike K2MK -- View this message in context: http://elecraft.365791.n2.nabble.com/Yamaha-CM500-and-ANTIVOX-setting-tp5827199p5827199.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

[Elecraft] [K2] Microphonic 18.157.9 (+/-) ?
Hi All, I ran across an interesting thing with my K2. I have a very pronounced microphonic at 18.157.9. There is a carrier (birdie?) on that frequency and when I tap on the top of the radio, the tapping is clearly audible in the speaker. Has anyone else noticed this ?

[Elecraft] XG2 Frequency Accuracy
Does anyone know the typical frequency accuracy of the XG2? If I had two XG2's, what would be the typical separation in frequency between the two of them at the 14060 setting?

Re: [Elecraft] XG2 Frequency Accuracy
Dave, The frequency accuracy of the XG2 will vary with the individual crystals. It is not specifically for frequency accuracy, but for level accuracy. In other words, I would not depend on the XG2 for any sort of frequency calibration unless you measured the output of a particular one with a calibrated frequency meter. 73, Don W3FPR On 12/11/2010 9:00 PM, David Gilbert wrote: Does anyone know the typical frequency accuracy of the XG2?

[Elecraft] An AGC Story
Bottom posted for context. Geoff GM4ESD wrote If I had a K3, before I changed the HAGC threshold my *first* measurement would be to look at the output of the SA612 mixer (with a spectrum analyser) while introducing two or more very close spaced signals into the antenna port, so that these signals do get through the roofer - as in a pileup. The objective, of course, would be to obtain an acceptably clean output from the mixer with non intrusive products over a wide range of input levels. IMHO the higher the HAGC's threshold can be the better, provided its control is tight enough when activated to protect all what follows. I made within DSP b/w IMD measurements on my K3 and comparable measurements on my K2. These were included in a post dated 5 December but you may have missed it. The following measurements relate to K3 S/N 4904 on 7MHz with 2.7kHz roofing filter and 2.7kHz DSP b/w. Default slow AGC was selected. The table shows input level at the K3 antenna connector for each of two carriers spaced 500Hz. At each input level, the level of the strongest IMD product observed at the AF output using an HP8568B is recorded alongside. -73dBm Better than -55dBc (Input S9) -63dBm -55dBc -53dBm -50dBc -42dBm -45dBc -33dBm -42dBc -23dBm -37dBc (Input S9+50) These figures are good and IMHO entirely acceptable. Some older transceivers would struggle to provide -35dBc at S9. I made a similar set of measurements with my old K2 S/N 997 -73dBm -50dBc -63dBm -48dBc -53dBm -45dBc -43dBm -48dBc -33dBm -45dBc -23dBm -15dBc Broadly speaking the K3 is as good or better than the K2, which is itself good. It is possible later mods to the K2 may have made it even better. The most recent mods to my K2 were carried out over 5 years ago. 73 Bob, 5B4AGN __ 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] XG2 Frequency Accuracy
Yeah, I understand that. I was just wondering how close they might be since I don't have a clue what the tolerance is of the crystals used by Elecraft. Specifically, I was wondering if they would be close enough (typically) to use for in-band IMD tests as a function of AGC settings. Or at least close enough that whichever one was higher in frequency could be easily padded down to within a few tens of Hz or so of the other. 73, Dave AB7E On 12/11/2010 7:22 PM, Don Wilhelm wrote: Dave, The frequency accuracy of the XG2 will vary with the individual crystals.

Re: [Elecraft] K3 PA IO TST Problem
That was it. I had tried it a second time per installation instructions. Tried a third time and there it went. Now I can continue the installation. There is another small mystery which can be solved later. When I go to fan 1 the fans jerk once but don't spin. Going to 2 3 and 4 they spin fine. If I go to e and then to 1 they continue to spin. Also if I start at 1 and flick the blades with my finger they run fine. Ill have to get out my VOM and check the supply voltage. Makes me think of that cell phone ad. With Elecraft you are getting thousands of support people.

If the test still fails then there is definitely a problem. Good luck.

Re: [Elecraft] [K3] Yamaha CM500 and ANTIVOX setting
I also recently replaced the Heil Proset for CM500, not because of hearing issues but better comfort in the long contests. I am not a big fan of vox, I use a foot pedal to PTT the rig. I turned on the vox just to see if I have same problem as you with CM500. I currently use front panel microphone connector with homebrew adaptor and I also currently don't use the K3 bias for the microphone, I still use the AAA battery pack that came with the headset for the bias. I played with the vox settings so the levels will be right and sensitivity of vox is correct. It is not difficult to do because the CM500 microphone is highly directional. Here are my settings at this point: MIC is 30 CMP is 20 In the Main menu: VOX GN is 010 ANTIVOX is 025 With these settings the vox works as it should. Knocking on the desk, dropping pen on the desk or normal breathing do not trip the vox. I don't know how loud are the signals you are hearing, my AF gain is at about 9 o'clock position to hear normal signals on 10m. The headset is closing the ears pretty tight, hard to believe that audio from the headphones is able to trip the vox. 73, Igor, N1YX -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike K2MK Sent: Saturday, December 11, 2010 7:57 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Yamaha CM500 and ANTIVOX setting I decided to try the CM500 headset in place of the Elecraft Heil Proset headset. I'm always on a quest for increased volume due to age related decreased hearing. To that end I can emphatically say that the CM500 solves my low audio level problem. The CM500 in the rear headphone jack provides greater audio output then the Proset in the rear speaker jack. So far, so good. I tried the CM500 on SSB today in the 10 meter contest and had occasional VOX tripping when listening to loud signals or loud noise. I'm using the headphones and there is no speaker output. (I even held my breath to be sure my breathing wasn't tripping the VOX). I reduced the VOX GAIN to 17. Any lower and I couldn't always trip it reliably. My ANTIVOX was set at 20 for the Proset so I began to crank it up. It's up to 80 now for the CM500 and appears to have solved the problem.
