Re: [Elecraft] Info 080 message started with RF Alignment and Test, Part II
I guess I said it wrong - I was referring to the VCO Test in Part 2 for the RF Board. After the PLL Reference Oscillator Test, I changed bands to 80 meters and was about to adjust frequency to 4000.10 when the Info 080 message popped up again. As I stated, when using CAL FCTR the frequency I found at this point (after the Info 080 message had appeared) was around 10800.00 - slightly above the 8 to 10 MHz range specified. However, it was fairly stable. After attempting another 456 reset this afternoon, the Info 080 message persists, just like it did before, with the same 0.00 frequency reading, and the same last character that looks like a 2 missing one segment (not a c). Additionally, something I didn't mention before but had happened before as well, when the Info 080 message appears at this stage, the LCD appears to default, or revert, to the day setting - the green backlight goes out. It just feels like a hardware issue to me, from what I've experienced with computer troubleshooting in the past. The same exact problems appeared at the same exact point in the tests...and everything else, test wise, had worked fine up until this point.

[Elecraft] KAT500 anomaly this morning
Woke up early and when I woke up the station, the KAT500 turned on when the P/S turned on, but instead of being in AUTO where it was when I shut it off (yes, I shut the KAT500 off first with the front panel button) it came up locked in MANual and the mode button would NOT turn it off or cause it to do anything else. No amount of button pushing in any combination would make it do anything but sit there with it's one green light on and stare back at me. Thinking there was a front panel board, holding the switches and LED's, that might have come partially unplugged in shipping, I pulled the top cover - WOW that is one nice looking board in there, but no front panel, everything is on the main board and it's all soldered in and 99 percent (except for the relays, MASSIVE toroids and air wound coils), surface mount. Nothing plug-in here. Hooked up the RS-232 cable and ran the utility program. It would not communicate with the tuner giving me a screen indicating that the KAT500 was waiting for the power button or a firmware download and after a while would timeout with the KAT500 not responding message. Could find nothing in the manual that indicated how to force a firmware load, so I in my banging mood, told the Utility program to install new firmware (I had downloaded the current version from Elecraft), started pressing and/or holding buttons in various combinations. Somewhere in all this, I managed to hit on the right combination to force it to accept the firmware download from the utility program and all is again well. I have no idea what caused the glitch (cosmic rays, Boeing's EMP missile flying over wichita, or Murphy crawling around in there), but it's apparently back up and running. I'll keep an eye on it over the coming days (weeks, maybe if it doesn't happen again) and try to find out what circumstances caused the problem. Meanwhile, Elecraft (separate message will be sent to support), PLEASE publish the RESET and FORCE FIRMWARE LOAD instructions where the casual observer can find it. Having that info in the operating manual would have been a HUGE help this morning.

Re: [Elecraft] [K2] POWER control has no effect on actual transmit power
Ben, It sounds like re-heating of the solder connections on both sides of C121 is in order. The fact that your RF voltage on terminal 3 of T1 has the proper ratio to that on terminal 1 implies that T1's solder joints are OK. The absence of RF on the driver (Q6 base circuit) side of C121 could be due to a very low impedance being presented there, but this would have been reflected in a much lower voltage reading at terminal 3 of T1 ** if ** C121 was properly connected. I would hesitate to operate the transmitter without the heat sink attached even for brief periods of time. Good luck, and 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-POWER-control-has-no-effect-on-actual-transmit-power-tp7564692p7564709.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
Re: [Elecraft] Info 080 message started with RF Alignment and Test, Part II
You have mentioned 4 problems now - the Info 080 problem, the LCD backlight, a missing segment on the last character displayed, and a zero frequency reading when doing the VCO test. Neither of those problems are related to the other problems, so I strongly suspect that your soldering is at fault. Check all your solder connections against the figures in the soldering tutorial that can be downloaded from the Elecraft website. 73, Don W3FPR On 10/28/2012 2:16 AM, AC8HU wrote: I guess I said it wrong - I was referring to the VCO Test in Part 2 for the RF Board.

Re: [Elecraft] [K2] POWER control has no effect on actual transmit power
Ben, When you have low output, it is normal for the RF voltages at the working stages to be much greater than the listed expected values. Since the Q5 output is higher than expected, but the Q6 input is zero (or close to it), you have a problem between Q5 and Q6. Refer to the schematic and check all components between those 2 stages. Normally I would say that toroid T1 is the most likely problem, but since you said the output RF voltage is 1/3 of the input RF voltage, I suspect something else - check for solder bridges. The only way you can do a TUNE or transmit without the heat sink installed is to remove T3. 73, Don W3FPR On 10/28/2012 12:09 AM, Ben Byer wrote: On Oct 27, 2012, at 6:23 PM, Don Wilhelm w3...@embarqmail.com wrote: On 10/27/2012 7:44 PM, Ben Byer wrote: I've had fun putting together K2 #7373, and am finally at the point of doing the 40-Meter Transmitter Alignment (manual, p.78).

Re: [Elecraft] K3 Problem
Yes, I also agree that CMP 30 is a bit much. On my rig, the open ragchew wide dynamic range setting is 18 and the in your face contest compression punch setting is 24. Any more than 25, and you start to reach the point of diminishing returns in inteligibility. I use the Yamaha Boomset here, so other mike's milage may vary. Also, pay attention to the mic level setting, which is also important. Both settings interact grately. Set the mic level first, then add CMP to the mix. Not the other way around. You shouldnt be afraid to light up all the lights on the right side of the meter consistently with the last light flickering with mod peaks. This is really an amazingly clean audio chain we are working with. But as in everything, too much of a good thing is often detrimental. IMO, K3's audio processing chain seems to like consistent input levels (still wish we could have attack and decay handles for CMP, Lyle!). The more consistent the input, by close talking, by keeping control of your voice, even if it is a P5 pileup, by managing the overall gain of your audio chain, and by keeping external noise down, the more modulation density you will get from this radio without sounding like something from Guns and Roses record.

[Elecraft] K3 Receive Sensitivity Consistency
When I turned the K3 on this morning, I decided to listen to 60m, to get away from the contesting.

Volume was considerably lower, but signal on the P3 looked consistent with the other bands. Going into the Menu and bringing the Receive EQ to +16 on all 8 frequencies did not restore the volume level. Using the Band switch, toggling back down to 75m brought similar results; lower receive level. However when going back to the original 2 Meg frequency and manually tuning up with the VFO, the sensitivity and volume remained consistent all the way up to the 5 Meg freq that I was trying to monitor initially. After that, going through the spectrum using the Band Select switch yielded consistent results. When using the VFO, I was looking for a magic relay click, or some crossed frequency threshold that triggered a return to sensitivity, but there was no degradation as long as I was going up the band with the VFO.

Re: [Elecraft] K3 Receive Sensitivity Consistency
Preamp, Attenuator, ATU, AGC were all checked before determining that the audio on 60m was lacking. The levels on the P3 were also checked to aid in determining the problem. RX EQ was all maxed out in able to overcome the inherit audio attenuation when the EQ settings are moved off of +16.

Re: [Elecraft] OT - 32 or 64 bit Windows 7
The only issue I had was getting the computer/rig interface working. My old computer had a real serial port so it was my first experience in USB/serial adapters. The one with the FTDI chipset worked fine with Win7 drivers. I never could find a Win7 driver that would work with the older Prolific chipset adapter. YMMV. There is a Windows XP compatibility mode you can set in the application's Properties dialog that helped me with a few of my older apps (not ham radio related). I've also heard mentioned some erratic CW being sent via N1MM due to USB timing issues but I haven't experienced it myself. I'm not sure that any of these are 32 vs 64 bit OS issues, however.

[Elecraft] K3 and sticking amp T/R relay
My newly acquired 30 year old amp comes with QSK. As there was a different relay than came stock I have to assume the circuitry may have been altered in the past. I have no way to know this. After two weeks of normal amp behavior I found the T/R vacuum relay had locked in the transmit position. A gentle tap on the NO terminal released it and function is back to normal. Mostly normal as I do find the ALC idiot light is no longer illuminating and the grid metering response appears attenuated but the amplifier puts out full power with absolutely no difficulty in that 35W drive gives 1500 out to the LP-100A watt meter. My question for here is; if the amp is not properly sequencing with the K3, what setting can I change within the K3 to provide more time for the amp's relays to close before the K3 transmits? I remember there was a feature to allow ms changes for QSK in the K3. How do I find that option? And should I decrease the MS time in the K3 or increase it to let the perhaps relay in the amp have time to close first to avoid hot switching?

Re: [Elecraft] K3 Problem
I run COMP=20 on my K3 with a Heil HM10-5 desk mic (older model I bought in 1998 with wide freq element). Get great audio reports on SSB on either HF or 2m-SSB. I have only modified Tx equalization for three lowest audio freq bands as mainly running conversational operating on a couple HF Nets and most operating is VHF+. I checked my COMP on the KX3 and it is only set to 8 with the MH3 hand-mic. On FM I had reports of overdeviation so lowered mic gain to 15. SSB mic level appears to work at that level without complaint. 73, Ed - KL7UW, WD2XSH/45 (500-KHz) __ 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] K3-PR10
Sorry - catching up on reading posts that I missed while traveling last week. I have a 6m preamp from another mfr on my K3, but would consider a PR10/6 combined preamp, if offered. At present I only have a single 6-element 6m yagi pointed toward US West Coast (az=115) so no issue with the 6m band. I will be adding a 1100w 6m PA and QRO antenna relay so the 6m preamp input will no longer connect thru the K3. I hope reinstall my repaired 3-elem 6m yagi fixed toward the NE from tower#2 at 45-foot so a second preamp would work well if it also would work on 10m (Hygain TH3mk4). The K3 ANT1 connects thru a couple manual coax switches for all other bands/amps/tuners/antennas. Next summer I hope to install tower#3 (30-foot) for the 6m 6-elem yagi which is for meteor scatter and eme work. I recently obtained a used rotator for that project. I had to remove my two stacked 3-elem 6m yagis this summer as the upper antenna director came loose and unreachable from the tower. I am redesigning and adding a 11-elem 2m FM yagi bolted to the tower at 45-feet (no rotator). Lower 6m yagi never tuned correctly and will be sold (cheap). Winter temps may affect these plans (currently 19F). 73, Ed - KL7UW __ 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] K3 and sticking amp T/R relay
Just a couple comments from one long in the tooth. Vacuum relays will last forever if switch unloaded, that is no RF current flowing. I have built many industrial power sources and never replaced a vacuum relay, UNLESS, the control sequence failed and allowed either power to be applied before the switch was closed or while the RF current was still flowing. Answer, VERY careful sequence keying even in QSK will let the relays last forever. While replacing the relay do a dry logic check of the keying sequence in time. Make sure you don't have a horse race to failure. IMHO.

No amount of button pushing in any combination would make it do anything but sit there with it's one green light on and stare back at me. Thinking there was a front panel board, holding the switches and LED's, that might have come partially unplugged in shipping, I pulled the top cover - WOW that is one nice looking board in there, but no front panel, everything is on the main board and it's all soldered in and 99 percent (except for the relays, MASSIVE toroids and air wound coils), surface mount. Nothing plug-in here. Hooked up the RS-232 cable and ran the utility program. It would not communicate with the tuner giving me a screen indicating that the KAT500 was waiting for the power button or a firmware download and after a while would timeout with the KAT500 not responding message. Could find nothing in the manual that indicated how to force a firmware load, so I in my banging mood, told the Utility program to install new firmware (I had downloaded the current version from Elecraft), started pressing and/or holding buttons in various combinations. Somewhere in all this, I managed to hit on the right combination to force it to accept the firmware download from the utility program and all is again well. I have no idea what caused the glitch (cosmic rays, Boeing's EMP missile flying over wichita, or Murphy crawling around in there), but it's apparently back up and running. I'll keep an eye on it over the coming days (weeks, maybe if it doesn't happen again) and try to find out what circumstances caused the problem. Meanwhile, Elecraft (separate message will be sent to support), PLEASE publish the RESET and FORCE FIRMWARE LOAD instructions where the casual observer can find it.

[Elecraft] KX3 in the Appalachian Mountains
I took my KX3 with me this weekend in the Great Smoky Mountain National Park. [IMG]http://i118.photobucket.com/albums/o117/KC8QVO/Backpacking%20Stuff/IMG_0478.jpg[/IMG] http://s118.beta.photobucket.com/user/KC8QVO/media/Backpacking%20Stuff/IMG_0478.jpg.html http://s118.beta.photobucket.com/user/KC8QVO/media/Backpacking%20Stuff/IMG_0478.jpg.html The picture is catching the sun rise at the Clingmans Dome parking area just before we hiked to the observation tower to start our trek along the Clingmans Dome portion of the Appalachian Trail (a bit over 3 miles). Along with me was a Yaesu hand mic, Sony earbud headphones, a jumper dipole (40-6m), and a solar panel to keep the NiMh AA batteries up. The whole radio set up was right about 5lbs. This is a world of difference from my FT-857D (about 15lbs trail weight without the solar panel). There was a contest going on this weekend and the CW portion of 40 meters was clogged with SSB so I wasn't able to make any contacts. The next morning I didn't have a whole lot of time to get the radio going. We ate breakfast and broke camp. We started out on top of Clingmans Dome and hiked down Sugarland Mountain. We were going to hike back up to Clingmans over the next two days, but I hurt myself and we were only 3000 feet in to a 4000 foot decent (then still had to make it all back up) so we called it quits and hiked back out to the road and got a ride. We dropped 3000ft in about 12 miles (a lot of it was up and down, not all down) the first day and 2 miles down another 1000ft (some up and down too) on the second day.

Re: [Elecraft] K2 SSB audio problem(an update)
After some extensive on the air testing with my Son, this is what we have found. One by one I eliminated pieces of equipment starting with the KPA500, then the KAT100, followed by removing the KPA100 from the K2, then changing power supplies, hooking the basic K2 to the 2.5A ps that I power the KX3 with. This ps is about 3ft. from the K2 on the floor, under the desk. In this configuration, the audio was clean. Even though not connected, I turned the KPA500 on(which is about 4 inches from the right side of the K2) and this introduced some small artifacts which would suggest that the VCO mod would be worthwhile. Following this, I reinstalled the KPA100. With the small PS still connected(the K2 does not recognize the KPA100), the bad audio problems returned. Disconnecting the small PS from the K2, and connecting the Astron 35m(which is about 2ft. from the left side of the K2) to the KPA100, but keeping power below 10 watts to keep the KPA100 off the results were no different. Turning the power up to turn the KPA100 on, the results were no different. Power output through an external watt meter closely follows the power selected. What now? 73, George, NC5G George, Ask yourself what has changed between good operation and now. Have you re-arranged your shack? The K2 is sensitive to devices with transformers positioned within 2 feet of the left side panel - the transformer's magnetic field modulates the K2 VFO. As a test, move your K2 away from everything else on the desk and run a test. If this proves to be your problem, you can install the optional mod kit, VCOSHLDKT. 73, Don W3FPR On 10/21/2012 10:48 PM, George Winship, NC5G wrote: After 11 years of operating and many unsolicited reports of great audio, I am suddenly getting not so good reports from my K2/100. Present setup is K2/100, KAT100, KPA500, and resonant antennas on 75 and 40 meters. Very rarely do SSB on any other bands. Stations seem to have trouble describing the problem. Reports vary from fuzziness, distortion, to clipping. I bypassed the tuner and amp, hooking feed line directly to K2/100 and also turned the power down to ten watts to shut off the KPA100 and problem persists. No difference between MH2 and CM500 mics. These test were done with stations who know my rig and my voice. This is an early K2/100. All mods were done years ago to K2, SSB, and KPA100. Receive audio is unchanged. Visual inspection of boards look OK. As a further check, I connected my KX3 to amp and antennas with great results. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-SSB-audio-problem-tp7564435p7564742.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
Re: [Elecraft] (Goes OT) Any report on compatibility of Win8 and the utilities?
Chuck, I downloaded and have installed Win8 on a second partition. Thus far, all of the Elecraft utilities have worked with a caveat - I installed the K3 utility and it worked fine. I installed the P3 utility and could not talk to the P3. At that point, I installed Fldigi and Flrig. Neither would talk to the K3 on the correct port (well, neither Fldigi nor Flrig saw *any* com port). I restarted Win8 and the problem was resolved. For whatever reason, once the K3 utility started, it didn't want to release the com port. After a restart, Flrig talked to the K3 through the P3 and also controlled Flidigi as it should. I have not noticed this problem again. I did not take the default install location and changed it to C:\Elecraft\... I have *not* been able to turn off UAC in Win8 as I have in Win7. Even though it should be off, I still get warnings. Oh, I almost forgot, when I installed the K3 utility, I got a Win8 warning. I do not remember the verbage, but I hit More Info and then Run Anyway (or something similar). I did not get this warning with either the P3 or KX3 utilities. I also got this warning upon installation of either Flrig or Fldigi but I don't remember which (it was not both). I also have a KX3 and I downloaded and installed the KX3 utility. I even updated the firmware on the KX3 with no issues. I will say that I hate/love the Win8 interface. If you've ever used Ubuntu Linux and gone from Gnome to Unity, it's a similar change. However, I think the new Windows interface is slightly (I mean slightly) more intuitive than Unity. I am slowly installing stuff on the Win8 partition. I may just buy a second SSD and install Win8 and Win7 side-by-side albeit on separate hard drives. There are actually two interfaces: 1) Metro UI - this is geared toward the tablet / touchscreen crowd, but it works okay with a mouse. To close an open app, you drag it to the bottom of the screen. I searched for a long time on how to do this. I never could find a close button. Also, in the Metro UI, all the apps pop up full screen. There is no way to resize a window in Metro that I have found. Again, think tablet. 2) Desktop - this is what most Windows users are familiar with. It works just as the previous versions' desktops except there is no Start button. Programs that are installed (if you choose to install a shortcut to the desktop) will give you an icon on both Metro and the desktop. I stated more than you asked and apologize for taking this OT. 73, Joel - W4JBB On 10/28/2012 10:51 AM, hawley, charles j jr wrote: Has anyone found any difficulties running Win8 in regard to using the Elecraft utilities for upgrade, etc?

Re: [Elecraft] KXPD3 APPLICATION NOTE UPGRADE SHEET TYPOS
You are looking at two different KXPD3 documents, Kent. Earlier KXPD3 all had the firm spring by default. After initial shipments and customer feedback, it was decided to build KXPD3s with the medium spring and include a firmer and lighter spring so the feel could be adjusted by changing springs. For those who already had KXPD3s with the firm spring, an upgrade kit was created that is documented by the KXPD3 UPGRADE KIT manual. That kit contained a medium and light spring for them to use for a lighter feel. That's why the upgrade kit document is a few days newer the original KXPD3 document. At the same time as the springs were changed, improved contacts were phased into the KXPD3. The new contacts are also included in the upgrade kit for those who had the early KXPD3s. If you got a KXPD3 with three springs, you do not need the upgrade kit. If you have an earlier KXPD3 and the upgrade kit, your key is now the same as current production. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of KENT TRIMBLE, K9ZTV Sent: Sunday, October 28, 2012 5:10 PM To: pa...@elecraft.com Cc: Elecraft Subject: [Elecraft] KXPD3 APPLICATION NOTE UPGRADE SHEET TYPOS Gents. . .

Re: [Elecraft] KXPD3 APPLICATION NOTE UPGRADE SHEET TYPOS
Yup, you're right on all accounts, Ron. But typosand confusion still remain. If the original paddle that shipped with KX3 serial number 21(kit version) had a firm spring, then why does my upgrade kit have an envelope labeledE980218 Spring, KXPD3 Firm? I don't need two firm springs. And how come the light spring envelope says E980239 when the parts sheet says E980236?Light is light, right? Surely there aren't two differentlight springs being shipped. And, in light of your reply, how do I know which spring came with the paddle to begin with . . . the firm or the medium? 73, Kent K9ZTV On 10/28/2012 9:57 PM, Ron D'Eau Claire wrote: You are looking at two different KXPD3 documents, Kent.
