Re: [Elecraft] Resistance Checks on pg. 45 (K3)
Hi Shane: First, congratulations on acquiring and successfully putting together your K3. You could not have chosen a better radio! The guys here have given you some good advice, but I'd like to suggest one more thing if you haven't already done so, which is to join a local club and get yourself an Elmer -- an advisor -- who can teach you some basic electronics, how to use your test instruments, etc. The ARRL ( www.ARRL.org ) is a good place to start, and specifically you can go to this page on their website to find a club nearby. ( http://www.arrl.org/find-a-club ) Be advised that different clubs have different areas of interest... some are repeater clubs, others are focused on contesting, and others are general interest / more diverse. There are plenty of technically oriented members in these clubs and I'm sure you will find someone who will be more than happy to guide you along the way. Best of luck to you and enjoy your K3. 73 de Andy, KD3RF / VE2DXY -- View this message in context: http://elecraft.365791.n2.nabble.com/Resistance-Checks-on-pg-45-K3-tp6605100p6615264.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] Could the be the basis for the KPA-1500?
One thing that someone pointed off off list. By having the amplifier and power supply on one board, if the power supply fails catastrophically, you have a lot of very expensive RF components attached to a burned up PCB. Separate PCBs would be a good idea.

[Elecraft] ANT1 vs XVTR OUT isolation
Hello, I'm newbie of K3. I have a little trouble: when I switch TX to RX and RX to TX and I transmit on ANT1 (I don't have ANT2), on XVTR OUT I see that RF comes out the BNC plug. I have tried to see how much RF is on XVTR gate, but I don't have little power meters, so I have watched with oscilloscope. I have found about 14Vp-p (that means 490mW or 27dBm) but only in the time when I switch PTT (few milliseconds). I have done all settings in CONFIG menu for installing an external transverter (and I had particual attention on these settings). I have also seen on manual, at page 39, last paragraph, a text that warns about isolation of XVTR OUT vs ANT1 and vice-versa. At now I don't understand if, when I TX in HF (expecially for contests), I need to unplug transverter from XVTR gates or not. I am afraid to broke my 144MHz transverter. Does someone has noticed this?

[Elecraft] KPA500 Remote
Folks - who out there has set up their KPA500 as a part of a remote station? I'm planning to do so here, and wondering whether others have used the pins in the AUX cable or plan to use software commands to turn the Amp on and off, etc. It appears both may be options. There also appears to be a pin in the Aux cable that indicates a fault condition, which would be handy to monitor remotely (I have a LP-Remote board from N8LP). I need to make a custom cable between the K3 and the KPA500 to connect some lines (band indication, auxbus?) and bring out others - the ON pin for the K3 that I currently use, the toggle ON/OFF pin for the KPA500, etc. So, what are others doing? I see there are options to connect the KPA to the K3 via RS232 not sure what that would buy me.

Re: [Elecraft] KPA500 Remote
Dana: There isn't an option to connect the KPA500 to the K3 via RS-232. There's an option to connect the KPA500 to the K3 via its 15-pin ACC connector. If you use that cable, the K3 can track band changes initiated by the amplifier, the amplifier will track K3 band changed without requiring transmission, and it includes the amp keying line and the ALC voltage.

[Elecraft] KPA500 - SWR
Hi Just finished building the KPA500 and it is a beautiful piece of work... I have an LP-100 RF Wattmeter and SteppIR 4 EL. The LP-100 says SWR is 1.35; the KPA500 says 1.8 (on 30 meters)... I can adjust the SteppIR of course - but then the LP-100 reads incorrectly? - the K3 by the way agrees with the LP-100 as to the SWR (much lower than the KPA500) The LP-100 is located AFTER the amp - so it reads the full output power. this holds true on all higher bands. any suggestions please? thanks and 73 John VE3NFK -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-SWR-tp6616176p6616176.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] KPA500 Remote
I'm operating my KPA500 remotely using the KPA Utility, and a direct COM port connection. I'm actually manually switching bands, changing from standby to operate, etc, through the KPA Utility too, for the moment. A note of caution; the RS232 port on my KPA500 has locked up 3 times now (requiring power cycle on 110V input to reset). The first time, I had to make an emergency drive in a freak spring storm to fix it. Whilst there, I moved the 110V supply to a remote-controllable power switch, so I can power-cycle remotely. That has saved me on subsequent occurrences. I need to get around to reporting this to Elecraft support. At least two of the cases were attributable to unintended high-SWR events. The KPA Utility's metering is of limited value, IMO, at the moment - the numbers jump around a lot between poll events when transmitting CW (at least). I'm using an LP-100A meter and its Virtual Control Panel for power/SWR metering (peak mode), which works well. 73, ~iain / N6ML On Sun, Jul 24, 2011 at 12:15 PM, Dana Roode dana.ro...@gmail.com wrote: Folks - who out there has set up their KPA500 as a part of a remote station?

Re: [Elecraft] KPA500 Remote
The KPA500 XCVR connector is used primarily to support Kenwood rigs that communicate their frequency via a serial port. If you want to control the amplifier remotely, you'll probably need to connect its PC-side serial port to some remote control program. The KPA Utility (as one example) shows you the amplifier's output power, SWR, PA voltage, PA current, temperature, monitors for faults, displays the current fault, has a button to clear the current fault, changes bands, switches between standby and operate, and turns the amplifier on and off. You can't do many of these things from the ACC connector. You can do some of them by remote control of the K3 (like change bands). You can pulse an ACC pin to simulate pressing the front panel power button. You can change the amp's band by controlling the transceiver remotely and transmitting. You can observe that some fault has occurred, but you can't read the fault code through ACC. There's no pin on ACC to switch the amp between operate and standby, or clear a fault.

Re: [Elecraft] Could the be the basis for the KPA-1500?
Nice demos and a reminder of just how dangerous QRO RF can be - to people and to property. In my commercial work I learned to be as careful around RF as I am around any high voltage - especially after accidentally drawing a small arc from an RF source. Messing with 50 or 100 watt Ham rigs from which we often drew an arc with a pencil from a high-impedance point made me careless. My QRO burn only made a small black patch on my skin, but it felt exactly like a nail had been shoved through my flesh - and it felt like the nail was still there for days! RF burns are deep burns that injure a lot of tissue and nerves. If I had been doing that YouTube demo, I'd certainly have worn the welding mask and more than that T-shirt in case some hot metal bounced around. Until now, a solid state amp could do limited damage because it would fail in milliseconds. The demos show these solid state amps are as robust as vacuum tube amps, and so they are just as dangerous. And we all should remember that one doesn't have to draw an arc or get a surface burn to do deep tissue damage from an RF field. That's why there are firm guidelines for RF field exposure. RF can set fires too. G3BDQ tells the story of the Ham whose end-fed wire ran through a hole drilled in his wooden window frame. Every time he held the key down a curl of smoke would come out of the hole.

[Elecraft] KPA500 Missing Screws
It was interesting to read that others have found screws missing from the KPA500 kit. I was missing all of the 4-40, 3/16 (4.8mm) Flat Head, Black screws. I was able to complete the build, but I was not able to button it up. I am dead in the water until the new screws arrive. I was able to scrounge a few of these screws left over from parts of other Elecraft projects but not enough to install the front and top panels. I am confident these screws will arrive soon.

Re: [Elecraft] KPA500 Missing Screws
Roy, Do you have any of the panhead 3/16 inch screws - like those that were used on the K2? If so, why not use those temporaily - they will hold things in place so you are not dead in the water. I believe all the flathead screws are used on the outside panels, so it would not require any dis-assembly (other than removing the screws themselves) when your correct ones arrive. 73, Don W3FPR On 7/24/2011 6:27 PM, Roy Morris wrote: It was interesting to read that others have found screws missing from the KPA500 kit.

[Elecraft] [k2] Poor USB audio after cal
About twice a year I like to run through the cal's on my K2. Today, I was unable to store the BFO adjustments to eeprom and I noticed that the USB audio sounds muddy. Almost like the RF pot was turned down and the 2k audio filter active. The RTTY (USB) mode also sounds like this. LSB and CW are quite loud and clear with a more believable S-Meter response. I was following the C22 cal Application Note procedure. The last few times I did this, the K2 cal'ed to within 10Hz of WWV. Before starting the cal today, it was 70Hz off. It is now within 30Hz post cal. The difference between TP1 and TP2 is negligible (limited by 10Hz DAC). My beat dial Freq. is/was 10.000.02 LSB (at this point when I triple checked the C22 cal) I used a soundcard program to watch the 10MHz WWV 500Hz and 600Hz tones while adjusting the BFO settings. Once it comes back to OPT1 from FIL4 the audio tones are back at their starting points and not were I set them. The BFO value did seem to save however. In LSB, the S-Meter showed S-3 (as did my other HF rig), on USB the meter was a solid S-9. The volume was not as loud and had more bass. I have a feeling this is just a matter of me forgetting a simple step but I can honestly say that I have followed the procedure word for word. I even double checked with the main K2 manual just to be sure. 73, Damon -- View this message in context: http://elecraft.365791.n2.nabble.com/k2-Poor-USB-audio-after-cal-tp6616641p6616641.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] Another KPA500 remote question
How much chatter between a remote control program and the KPA500 can be tolerated by the KPA500 microprocessor? As others have noted, and I have seen as well, the power readings reported on the RS-232 line are instantaneous snapshots. In a true remote situation, you need many readings a second to get a good idea of the peak or average power level that you are transmitting on SSB. So between power readings (many per second), queries for fault values (maybe once per second), and temperature readings (one every 10 seconds) - how much is too much? Alternately, could a new command be created that uses the micro to accumulate on a running basis (8/sec) and report when asked the last 1/2 or 1 second of peak forward power and VSWR? That would reduce the RS-232 chatter and provide much more accurate information.

[Elecraft] KC9EHQ New KSB2 revision issues
Hi All! I already E-mailed Wayne about this, but I thought I would share this with the rest of the group in case anyone got one of these recently and hasn't assembled it yet. I bought the KSB2 with my K2...Unfortunately, when I bought the radio and options, the KSB2 was out of stock. It took a few weeks to get this option because some components were no longer available, and Wayne and the Elecraft team had to perform some redesign work. I got one of the new boards, and the assembly was going by swimmingly this afternoon until I hit a snag...ALL if the 1N4007 diodes will NOT fit into their holes because the leads are too thick. This is more than a tight fit...They just plain don't want to go in at all. I am not going to attempt to widen the holes on my own as there isn't much real estate to work around, and I don't want to damage traces. Just an FYI, and no need for replies. 73, David, KC9EHQ K1 s/n 2051 K2 s/n 7164 __ 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] [k2] Poor USB audio after cal
Damon, The procedure in the manual is written for the average filter (of which very few exist), so I highly recommend you use the procedure documented on my website www.w3fpr.com dealing with K2 Dial Calibration instead of the procedure in the manual. The entire procedure involves 3 steps - first adjusting C22 using the N6KR method which needs no tools if you have perfect pitch, but those without it can use Spectrogram or a similar computer application to tune WWV right on. After setting C22, run CAL PLL followed by CAL FIL. The article has several links to supporting information should you need it. BTW - I am working on a Technical Note document that may be placed on the Elecraft website in the future dealing with exactly this same information - stay tuned, but in the meantime, use the information on my website. Once calibrated, the K2 will not drift because the settings are stored in digital form and are not dependent on any oscillator other that the PLL reference. I know that many K2s that I have worked on have retained their calibration information for several years. If you have trouble with the CAL PLL or CAL FIL routines not storing data into EEPROM, that is a separate problem and must be resolved before you attempt the calibration and filter alignment procedures. 73, Don W3FPR On 7/24/2011 7:05 PM, KC5CQW wrote: About twice a year I like to run through the cal's on my K2.

I'm just finishing my KSB2 board, and I did encounter this problem at only one hole, the cathode for D1.

Re: [Elecraft] KC9EHQ New KSB2 revision issues
That is a possibility, and if so, makes it an isolated case (I would hope that is true). It is *possible* to drill out the holes (but certainly not recommended). If that is done, it will be necessary to solder the lead on both the top and bottom of the board (because the thru-plating will be destroyed). For the KSB2, that would mean mounting the diodes far enough to solder between the board and the component body (the diodes on the KSB2 board are mounted vertically). 73, Don W3FPR On 7/24/2011 10:06 PM, Allen Wisbey, W1SBY wrote: I had a similar problem with my main board on K2 6688.

Re: [Elecraft] [k2] Poor USB audio after cal
Damon, Well, I certainly hope your flux cleaning efforts have not created problems. It often does create leakage paths that can cause problems. Solder flux by itself is non-conductive, and is best left alone - but when combined with many flux cleaning ?solvents?, conductive paths can be created that will cause insurmountable problems. I have seen attempts at removing flux which resulted in complete failure for the kit. Conductive paths can be created under connectors, under ICs and any other component. If you want to be safe, *do* *not* attempt to remove solder flux. If it gets really nasty in one area after several re-work attempts, you can remove the excess flux from that area with alcohol applied sparingly with a Q-tip and dried immediately. Use of a solder with a mildly reactive flux will leave almost no flux residue - Kester 285 is one of that type. Kester no-clean solder is another that works well. Save the Kester 44 with its Highly Reactive flux for antenna projects and wires that have developed some oxidation over time - it leaves a lot of flux residue, but cleans nicely - that kind of cleaning is not necessary on new boards and new components. Yes, I know that Elecraft recommends Kester 44 (among others), but only because it is OK to use (provided you do not try to remove the flux residue). IMHO, it is not the best choice for new construction. 73, Don W3FPR On 7/24/2011 10:14 PM, KC5CQW wrote: TNX for the info. I'll go over your method in detail tomorrow.

Re: [Elecraft] [k2] Poor USB audio after cal
I guess you know that it is NOT recommended to try and remove the flux from the boards after construction... if you don't get every bit of it off after you dissolve it with whatever solvent you're using, you'll end up with a severely contaminated board and future problems with it. If you have used quality solder as recommended by Elecraft, there should be no reason to apply extra flux during construction nor any reason that you would need to clean the board after soldering.

Re: [Elecraft] Another KPA500 remote question
On Sun, Jul 24, 2011 at 5:32 PM, M Cresap m.cre...@yahoo.com wrote: How much chatter between a remote control program and the KPA500 can be tolerated by the KPA500 microprocessor? As others have noted, and I have seen as well, the power readings reported on the RS-232 line are instantaneous snapshots. In a true remote situation, you need many readings a second to get a good idea of the peak or average power level that you are transmitting on SSB. So between power readings (many per second), queries for fault values (maybe once per second), and temperature readings (one every 10 seconds) - how much is too much? Alternately, could a new command be created that uses the micro to accumulate on a running basis (8/sec) and report when asked the last 1/2 or 1 second of peak forward power and VSWR? That would reduce the RS-232 chatter and provide much more accurate information. The latter is what I had envisaged. Peak current would be appropriate too. ~iain / N6ML __ 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] Elecraft CW Net Report for July 24th 25th, 2011
Good Evening, Propagation was better this weekend. There was a contest to avoid on twenty meters but I got a number of folks checked in there. Some QSB to fight but mostly lots of rabid contesters. On forty meters I had one op with a new 500 watt amp from Elecraft. Woo it was loud! I kept copying his call as AE6II but Dale disabused me of this notion. Must have been an artifact of my eardrums touching :) Phil was quite loud too. He gave a report of 85 degrees at the beach. Up here it was a little cooler at 77 but even now it feels sticky. I had a towel under my arm while running both nets and need another one here to type. But the sticky weather will not last long. Tomorrow we are due for another spate of 50 degree temperatures and rain. We are getting summer in short day or two doses this year.

Him living in California was just not right :) Hopefully I will not get too much more rain so I can get out in the forest. Time is a wasting, winter is almost upon us. At least so say the foxgloves. Now it is off to the cutting and splitting area for me. I will cease being so lazy and get to work at something other than a keyboard.

Re: [Elecraft] P3 for other uses
There actually is an undocumented feature that makes it easy to tune the P3 to any frequency in its range (a couple hundred kHz to 22 MHz or so). In the Xcvr Sel MENU item, select the last item in the list (labeled 0 Hz). The indicated frequency is now the actual input frequency. The tuning rate depends on the SPAN. Select 200 kHz span for fast tuning or a narrow span for fine tuning. However... On Sat, 2011-07-23 at 19:55 -0700, Vic K2VCO wrote: Yes, it would probably work.

That's right. If you do this I strongly recommend you put a pair of back-to-back diodes in parallel with the input to protect it from static discharge. Eric blew up an RF input board when he was walking around the roof of the factory with a P3 looking for the source of some RF interference. Apparently he touched the whip antenna he was using to something metal which caused a static zap. If you don't want to modify the P3 you could wire up a plug-in diode protector using a BNC T connector that can then be disconnected when you want to use the P3 with a K3 again.
