[Elecraft] [K3] Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?)
I'm considering adding a THP HL-1.2KFX solid state amp to the K3S station I have, and was wondering how others have done this. There seems to be conflicting info on the "right way" to do things. 1. The THP manual states that ALC should be used to control the amp, but 2. Elecraft support (and documents) suggest that ALC should not be used for any amps. Of course, that begs the question "Why is ALC included at all on the K3/K3S?", but...anyway. Elecraft support suggested I ask the reflector what other folks do, so I am. Looking forward to your replies.

Re: [Elecraft] OT: E-Bay charges
Hi Ken, I think you must have an eBay Store, because that is the only way fees could be that low. In that case, you have to pay a monthly "Store fee" to get that rate. If you are doing high volume, that makes sense. http://pages.ebay.com/sellerinformation/stores/Subscriptions.html For the regular user, having a store doesn't make sense. Fees for regular folks are 10% on the final value of the auction price (more if you have a reserve price or other options). Plus, PayPal takes ~3% off the transaction off the top. Then, eBay takes 10% of the amount of shipping you charge, too (!). http://pages.ebay.com/help/sell/fees.html If a regular seller (not someone with a Store) can get away with not using PayPal, I'd love to know how. I'm not saying it can't be done -- but I guess I haven't figured that one out yet. ;-) -john NE4U On Fri, Feb 26, 2016 at 10:53 AM, Ken G Koppwrote: > Hi John! > > I have a 100% rating for about 200 transactions and AFIK, E-Bay's fee is a > bit less that 4% and PayPal use is not a condition of use. > > Virtually all of Rose's case and cover orders are paid via PayPal.

Re: [Elecraft] Best Place to Sell Equipment?
I've done business on eBay, eham.net classifieds, and swap.qth.com boards. All have yielded acceptable results. I've never been burned at any of them as a seller. I recently sold my K3 on eBay, but would've preferred to sell it on eham.net or swap.qth.com. eBay, as you know, takes about 15% off the top (including the required use of PayPal). So, figure on that... The fellow who bought my K3 on eBay could've received a hefty discount if he had bought it from my eham.net or swap.qth.com listing, as the price there was 15% less. His loss! ;-) 73 -john NE4U __ 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
[Elecraft] RESOLVED (was: acceptable network switch (aka Linksys produces birdies))
I don't want to say it was the Linksys network switch -- but "it was the Linksys network switch". Just replaced it with a Netgear switch with a metal enclosure (GS305, for those keeping score at home). Plugged it in, plugged in the network devices (VoIP phone, laptop), and went downstairs to scan the bands for potential issues. The Linksys, as you may remember, produced noise every 30kHz or so on 40m (worst) and also on other bands. It was S9+ noise. Really irritating. The Netgear produces no such noise on 40m or any other band that I can discern. So, it's nice to have this resolved without having to re-wire the entire house or search out another part to replace. :-) Thanks for all of your help -- and I highly recommend the Netgear GS305 if you are looking for a 5 port network switch! 73 -john NE4U __ 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
[Elecraft] data modes (USB/LSB or DATA) using KIO3B sound card interface
I looked in the K3S manual, and the instructions on setting up data modes (p. 33) fail to mention the use of the KIO3B internal sound card. Are there instructions (erratum?) available on how to set up data modes (using DATA or USB/LSB) with this new feature? Probably a simple answer to this question -- I'm just having trouble finding it.

[Elecraft] KAT500 utility works -- then doesn't
Hi all, After finishing up my K3S build with only one incident (the 400Hz filters mysteriously not working in the new rig -- they are now at Elecraft for testing, FYI), I am reconnecting my K3S and the rest of my station. Finally, I got motivated to finally get my KAT500 connected to my computer! I installed the latest version of the utility and all was good. I was able to view the SWR and FWD/REF power as the unit trained itself (after clearing the memories, first). Then, without warning, the utility stopped recognizing the KAT500. The COM port is still there and it hasn't changed, but the KAT500 is no longer found. Many options are now grayed out. I've tried changing the COM port assignment for the KXUSB adapter, but that does nothing. I tried removing then reinstalling the adapter, which also results in no change. Any ideas what is going on? Could RF have somehow gotten into the controller in the KAT500 to make it not respond to the KXUSB polling? The KAT500 still tunes as usual, but I'm just not able to access the unit at all via the computer interface. Thanks for your help. -john NE4U __ 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
[Elecraft] closing out some K3S issues ("failed" 400Hz filters, failed KXUSB)
OK. I have to come clean and admit that despite more hours with a soldering iron than I would care to count, I made a major error when I completed my recent K3S build. You know that REF CAL procedure where you zero beat WWV? Well... let's just say that I somehow managed to set the oscillator to a value way out of the expected range. I swear I heard that slow beat note about 2Hz away from where the value should have been, but now I don't know how. I re-did the REF CAL procedure using 15MHz WWV today, and now things are hunky dory. The gents at Elecraft provided too much kind support to help figure out my problem and I hope they can forgive me for the time of theirs I wasted. :-) Now, as for the KXUSB not communicating with my KAT500 -- that one is still a mystery, but it appears to be an issue with a KXUSB instead of the KAT500 (whew!). I crafted a serial to stereo cable to connect the KAT500 to my computer, and things worked just fine the first time. I hate to use that serial port for this, but I may have to as the KXUSB is out of warranty (purchased November 2014) despite its first use being last night. Ah well. Thanks for listening, and I hope that this can be a lesson to each of you. Take time on your builds. Don't stay up too late, or do things when you're tired -- or you might completely mess up the REF CAL procedure and cause your narrow filters to "fail". 73 -john NE4U __ 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] slightly OT -- acceptable network switch (aka Linksysproduces birdies)
I tried putting loads of mix 31 toroids on the lines, and it did very little. I'm wondering of moving to gigabit will change things. I tried using different power supplies I had on hand, but those had absolutely no effect on the noise.

[Elecraft] K3S audio disappears with narrow filter selection
Hi, I completed the build last night, and I am putting the rig through its paces. I previously had a K3, so I am familiar with the menu and configuration. I configured the filters in the K3S as follows FL1 - 6 kHz FL2 - FL3 - 2.7kHz (-0.95 offset) FL4 - 700 Hz (+.04 offset) FL5 - 400 Hz I have tuned to a strong carrier (on CW) and then progressively narrowed my bandwidth. When I hit FL5, the audio is strongly attenuated. It basically disappears. I thought that something was wrong with my configuration, so I checked it again. FL5 was set for 400 Hz, which the filter in FL5 is. I performed several experiments. Choosing the filter with the XFIL button does the same thing. Audio is present with FL3 (2.7kHz) and FL4 (700Hz), but gone with FL5 (400Hz). Then, I went into the firmware and changed the bandwidth of FL5 to a narrower value (e.g. 250 Hz). I returned to listening to the audio and using XFIL produced the same results as before; however, when I tuned down from 700Hz to 400Hz, the audio was still there. When I went to 300Hz it was still there -- but it disappeared at 250 Hz (as I had set the filter's bandwidth in the firmware). Help! There's gotta be something simple but critical I'm missing...somewhere. Before you suggest it -- yes, I have tried to up the dB of the filter compensation for FL5 (400Hz). I increased it to the highest value, and the signal is still basically gone -- but maybe slightly higher. -john NE4U __ 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
[Elecraft] slightly OT -- acceptable network switch (aka Linksys produces birdies)
I just completed my K3S build and initial configuration. Woohoo. I was tuning around the bands, and I noticed birdies *everywhere*. Every 20-30Hz on 40m there was one -- and it was LOUD. I thought that something was up with my build, but then started doing an internet search for "K3 birdies". I saw one person (from a 2010 post on this list) note that the birdies could be coming from network devices (routers). A-ha! Initially, I thought it had something to do with my ASUS wireless router being extremely close to my operation location. I unplugged it, and the noise went away. Then I plugged it back in and removed, one by one, the connections to various devices (network storage, my shack computer, and the line that runs to my upstairs office). It just so happens that I had installed a network switch recently (produced by Linksys, and on sale at Best Buy last week). I unplugged the cable going to that switch, and the noise went away. I then plugged it back in, and went to the office and disconnected the power from the Linksys switch. Noise is gone again. So, I'm looking for a new network switch. Does anyone have advice on what has worked for them? Alternately, any idea on how to get the network switch from producing these awful birdies? I'm *not* looking for a new router -- but just a switch.

Re: [Elecraft] What crystal filter do you use the most?
I am one of those folks who has the INRAD 700Hz filter (special-ordered by the guys at UNPCBs, http://www.unpcbs.com/). I use it exclusively for scanning the bands on CW. When I want to get tighter, I have the 400Hz filter below that. I've found that combination works wonderfully for me. For SSB, I just have the stock 5 pole filter. I also have the AM filter, but only use it for SWLing. 73 -john NE4U Madison, WI __ 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

[Elecraft] [K3] autotuner for K3 with AL-811 amp (KAT500 or other) / random wire antenna
Hi all, I've been enjoying using an AL-811 to help bust the pile-ups with my long wire antenna and Dentron Super Tuner Plus (manual tuner), but would really like to add a QRO autotuner to the mix. Currently, my K3 and AL-811 sit on my desk. The Dentron sits about 15' away on top of a bookshelf next to the basement window where my antenna enters the shack (one wire for the radiator and one wire to the radial field). The Dentron has a random wire and ground post on the rear, which makes tuning this antenna a breeze (but I have to get out of my chair and re-tune whenever I switch bands). I'm considering the KAT500, but wonder how it would work for this situation. Here are my two (please suggest more) solutions: 1. Put the KAT500 right next to the K3 and AL-811 on my desk, run a 15' long 50 ohm line to a balun which would attach to the antenna outside my basement window. Computer control is easy because the KAT500 and K3 are right next to each other. 2. Put the KAT500 right next to the antenna and run a short (2-3') 50 ohm line to a balun which would attach to the antenna outside my basement window. A 15' line from the amp to the tuner would be required and no computer control would be possible. If I go with Option 1, then I am trying to match the 50 ohm line for 15' before I get to the balun/antenna outside the window. If I do with Option 2, then I won't be able to use the K3/KAT500 AUXBUS features (I had emailed Elecraft support about this in the past and they suggested not using a 15' long AUXBUS connector). Anyone else tuning random wires with the KAT500? How do you do it? Should I be considering another tuner altogether? I don't want to break the bank, but I do want a workable solution. 73 -john W4PAH Madison, WI __ 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

[Elecraft] [K3] KRX3 rave
Possibly the best option for the K3 (beyond a good set of filters) has to be the KRX3 sub receiver, in my opinion. I have found this especially helpful in quickly and easily finding the worked station for split operations. With all of the W1AW/x operations this year--most of them running split--being able to listen to them in one ear and search for the portion of the band up where they are working has been an invaluable time saver and increased my successful QSO rate. It's the same case when DX stations are calling on one frequency and listening elsewhere. I can just quickly tune the sub and find the QSX frequency within 2-3 calls usually. Win! It was a tough decision for me when I was building my K3 system. I wasn't sure if I wanted to choose the P3 or the KRX3 (and I couldn't afford both). I went with the KRX3 and feel like I made the right decision for me. What a great accessory! 73 -john W4PAH Madison, WI __ 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
[Elecraft] [K3] SSB no output

I am trying to use the TUNE button to help provide a constant carrier, as I always do, with my external Dentron tuner. Everything works great--except it is exhibiting strange behavior on 15m. When I hit TUNE it won't hold the TX 15W (what I have set as the output power). In fact, it shows 0W and won't stay on at all. Any help?

[Elecraft] K3/AL-811 questions
Hi all, This could be tangentially related to a K3 issue, or maybe K3 experts can give some insight here. FYI, when I am not using the amp, I can get 100W from my K3 with no problem. Please keep reading... I have been using my AL-811 (not new, but new to me) successfully at 500W for the past few weeks. Recently (actually, the second time this has happened), my fuses both blew and I replaced them. Since I replaced them, behavior has not been typical. I can't get anything over 200W (most is in the 175W range). I use a tuner after the amp, and I know that the antenna is matched quite well to the amp, but my SWR meter on my rig (K3) is showing a high value. When I tune up at 20-25W I can get about 100W out from the amp. When I move to 50-65W I get 200W. And there is clicking. I can't tell if it's a relay or if it's something else. So, the main issues are 1. High SWR from the rig to the amp (when the antenna is 2:1 SWR to the amp) 2. Low power from the amp to the antenna Happy to provide other information if folks have ideas on where to look.

Re: [Elecraft] K3/AL-811 questions
I called Ameritron/MFJ and they suggested that the tubes were bad and that D16 may possibly be bad as well. Apparently that has to do with metering. Another fellow (off-list) suggested that the GFCI blowing has to do with a leak to the ground. So, that could be a bad tube, right? Or something else... Guess I should start with tubes.

Re: [Elecraft] [K3] KRX3 installed and ERR VCO / ERR PL1
Even though it's quite embarrassing, I wanted to let folks know about the resolution of this issue. It's also great to have my problem and solution live in perpetuity on the list in case someone else has this issue arise when they are adding their KRX3. To recap, the issue I had was that neither my main nor my aux KSYN3 would complete the calibration procedure if there was a KSYN3 installed in the aux slot. If there was just a KSYN3 installed in the main slot, everything was hunky dory. I tried adding DeoxIT to the slots where the main and aux KSYN3 are installed. That made it easier to remove/replace the units, but didn't help the main problem at all. I checked the voltage at J1 and J2 of the KREF3 board, and they were both within range (a little over .9V). I double-checked to make sure that all the TMP cables were in place, and that all the plug-in modules were aligned correctly. *Finally*, I checked the bottom of the board one last time, especially the work I had recently completed (a couple of upgrades and adding a resistor to change the value at R91). My error was in the resistor didn't have a good soldering joint at the point where the leaded add-on 27 ohm resistor was added and where the 100 ohm SMT resistor was previously. I reflowed solder there, and then voila, the rig will complete the calibration procedure for both KSYN3 modules! When I was checking the resistance before, I think I was inadvertently pushing the leaded resistor against the SMT resistor, thus making a connection (albeit temporary) and showing the expected value of 27 ohms. D'oh! Thanks again to Gary and everyone on the list for their assistance. I'm looking forward to playing around a bit with the newly upgraded K3 this weekend. 73 -john W4PAH Madison, WI On Wed, Sep 5, 2012 at 11:35 PM, John Shadle sha...@katzenfisch.com wrote: Hi, I completed the installation of my KRX3 this evening (and upgraded the DSP board on my main RX, too).

[Elecraft] [K3] splitting RS232 output for 2 serial ports
Hi all, I'm trying to accomplish keying with my K3 using the RS232 port and a COM port on my desktop computer. I currently use the RS232 for station logging to provide frequency, mode, etc. information and for rig control (e.g., click on a spot and then the radio changes frequency/mode). Unfortunately, the program I use (AC Log by N3FJP) does not allow you to choose the same COM port for both rig control and CW keying. My question is whether or not I could use a splitter of some type (at the K3) to go to 2 separate ports (e.g., COM 1 and COM 2), then use COM 1 for rig control and COM 2 for keying. Has anyone else done this? Is this acceptable practice?

Re: [Elecraft] [K3] splitting RS232 output for 2 serial ports
Do you think there would be a problem in letting both signals pass through to both COM ports? Wouldn't COM 1 only look for the appropriate rig control signals and COM 2 only look for the appropriate CW keying signals? Or not...?

Re: [Elecraft] [K3] splitting RS232 output for 2 serial ports
Thanks, Don. Are you talking about the PTT IN and KEY OUT RCA jacks? I Googled one transistor keying circuit and it came back with some amplifier keying circuits. Is that what I should be looking for, or something else? I'm sure the answer is obvious, but I'm just having a hard time seeing it. ;-) Take care. -john W4PAH On Tue, Aug 7, 2012 at 6:20 PM, Don Wilhelm w3...@embarqmail.com wrote: John, I would suggest that you use the one transistor keying circuit (Google and you will find many sources) for the keying and PTT. Connect the output of the one transistor keyer to the K3 rear panel keying input and PTT input. You will still have the problem that the computer will activate those signals when the computer boots, so boot the computer and than turn on the K3 - or take other common sense precautions like switching the K3 to a dummy load during computer boot times. 73, Don W3FPR On 8/7/2012 5:38 PM, John Shadle wrote: Hi all, I'm trying to accomplish keying with my K3 using the RS232 port and a COM port on my desktop computer.

[Elecraft] [K3] GFI outlet, 100W on 20m, and *poof* (RFI?)
Hi all, I realize that this is tangentially related to Elecraft gear since I'm using a K3 and experiencing this issue, but I thought someone else may have some knowledge to share with me to help me solve my problem. Recently I stopped using a 25' long extension cord to power my computer, power supply, and other accessories and installed a 2 gang box directly off of the main electrical panel, where my shack happens to be (in the basement). While our basement is waterproofed, it still has a concrete floor, which requires a GFI outlet (according to my electrician). To do my due diligence, I installed one GFI in the 2 gang box and 1 regular 3-prong grounded outlet. I have my shack computer, my power supply, and my transformer for my SGC SG-231 autotuner plugged into this. Last night I tuned up (15W) 20m and was hoping to work some DX. My SWR showed 2.0:1 on my SWR meter and on the K3. All is good. When I keyed down with 100W, the GFI tripped and my shack computer, power supply, etc. shut off. I'm using Leviton smartlockpro 20A GFCI outlets from Home Depot. They're not cheap, but maybe they don't have adequate RFI protection (obviously). I suppose the first solution is to remove the GFI from the situation, but I thought using it was the right thing to do. Any personal anecdotes or advice would be welcome.

Re: [Elecraft] [K3] N3FJP rig control settings?
Hi Terry, I have been using N3FJP's AC Log for a while, both with my K2 and now my K3. I haven't had any trouble at all with DX spotting and clicking on a spot to do a frequency change with either rig. I can take a look at my settings if you like. So, basically, clicking on a spot doesn't work? You're getting the wrong mode and even frequency? That's strange... N3FJP recently updated AC Log and it's a much improved program. It's now at version 3.2 (although I have only upgraded to 3.1 so far, myself). If you purchased it in the past, you're entitled to a free upgrade. It might be best to try to post your question to the AC Log list, too. I've found Scott and the rest of the list members invaluable in setting up the software. http://groups.yahoo.com/group/N3FJP_Software_Users/ 73 -john W4PAH Madison, WI If anyone has been successful in finding a way to send DX spot rig command strings *smoothly* from N3FJP's ACLog to a K3, would you please email me with the software settings you've used. I have not been able to get ACLog to interface well with my K3 (#474) since I bought the rig (the software worked fine with my FT1000MP). The software reads the K3 data just fine. But DX spot clicks seem to go very slowly and the mode, band and frequency changes seem to be all mixed up. Scott, N3FJP, told me that Elecraft sends the commands to the K3 in a non-standard format but claims to generally support the Elecraft line. The command string references I have found in the K3 manual have not been successful, but I don't rule out an error on my part there. Other than recommending other logging programs can anyone offer an ACLog command solution. I'm not a contester and have tried all the popular logging/rig control offerings that many of you use. Most programs offer WAY too many features for my needs. Many thanks. 73, Terry, W0FM __ 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] 8-pin to stereo mic cable?
Thanks for the clarification, Don. I was reading my hard-copy manual (Rev. C1, November 18, 2007) and it states on p. 26 that An 8-pin to 3.5-mm adapter cable is available (pg. 42).. However, on p. 42 there are two headings--Options and Firmware Upgrades--and no mention of this cable, so that left me confused. So, the cable doesn't exist, I suppose?

[Elecraft] [K3] using a footswitch for PTT
Hi all, I am finally getting the ol' radio back up and running after a few months of packing and moving from NC to WI. In my past life (in NC) I was mostly CW, but now that the shack is in the basement I want to get back on SSB. I have an Elecraft desk mic (the Heil version from a few years ago). It has an input for a 1/4 footswitch controller for PTT. I've never used a footswitch before, so this is all new to me. I don't have a Heil footswitch, but do have an older Yamaha foot pedal which I picked up at a yard sale a couple of years ago. It creates a closed circuit whenever I depress the switch (and is open otherwise). The odd thing is that whenever I plug in this footswitch, the PTT is engaged when the switch is plugged in--and the PTT is disengaged when I depress the switch. This seems like odd behavior to me. Is there something in the menu that I need to change? Advanced mic parameters? I'm kinda lost. I cracked the case open to view the innards, but it's just two wires (tip and ground for the 1/4 cable) and a switch. I don't think there's anything I can do in there to modify things. The model appears to be a Yamaha FC5 ( http://usa.yamaha.com/products/music-production/accessories/footswitches/fc5/?mode=model), although I can't find a model number on it.

[Elecraft] KXPA100 timeline?
I see that KX3 Ordering and Shipping dates will be Fall-Winter 2011 according to Elecraft's web site (http://www.elecraft.com/KX3/kx3.htm). Will the KXPA100 be available at that time as well? If so, have any more details been released about it (kit like the K2 or semi-kit like the K3; price range; cost of the KXAT100 autotuner)? Also, are any details available on how it will integrate with the K2? It would be cool if it would integrate similar to the KPA100 in that you can have continuous selection of output power from 0-100W. Just a thought... :-) Thanks! -john W4PAH __ 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] wire antenna lengths for portable operations
I'm headed up to KL7-land next week and am going to take the K2 with me. I was thinking about using the KAT2 to tune a wire attached to the BL2 (at the 1:1 setting). Probably going to cut some teflon-coated wire this evening and pack it away in the bag. I'm seeking input on the best lengths of wire to cut for the active part of the antenna as well as the counterpoise. If you have any other comments on this setup, I'd love to hear them, too. In the past, I've used the K2 attached to my homebrew vertical (SGC SG-239 at the base of a elevated ground plane vertical), so this is my first adventure with random wire antennas.

[Elecraft] [K3] multiple error messages on start-up
This is odd. Just finished a QSO with J5UAP on 30m this evening and then switched over to 40m to pursue some more DX. When I got there, I wasn't able to get any power out. It showed 0.0W when I tried to TUNE (I have a remote tuner at the base of my vertical). I power cycled the radio and then received a multitude of errors upon power-up (including ERR IO1 and ERR PL1 among others). In addition to that, the fans were running (I have the 100w amp as well). I turned the radio off for a minute or so, and now the error has resolved. I've had the issue of the no power out when TUNE-ing in the past, but never this before.

Re: [Elecraft] [K3] multiple error messages on start-up
That was my first thought, Ron. I had previously had my TUN PWR set to 25W, but when I looked at that menu item it was set to 12W. I had not changed the setting. The KPA100 was no offline in the config menu at all. I reflashed the firmware and now it's all working, I think. The LP-100A wattmeter is showing about 75W out with a 1.6 SWR into my antenna (the K3 says I'm getting 100W out). That seems a little low to me. Next I'll try a dummy load... The investigation continues. -john On Wed, May 4, 2011 at 10:46 PM, Ron D'Eau Claire r...@cobi.biz wrote: Wow! I've not had those issues turn up on my K3, but suddenly not getting more than 12W out sounds like the KPA100 is off-line.

Trying to raise money for a new transceiver and am going to bring my K2 back to QRP by selling these accessories. This is for a KPA100 ($399.95) mounted in an EC2 ($79.95) with the KAT100 ($219.95). Total value is approximately $700. The KPA100 was built by KZ1X and has all of the updates which make it up to current spec. The KAT100 was built by me (W4PAH) this past year. All you have to do to have 100W and an autotuner with your QRP K2 is connect the two with coax (and add an external coax jumper between the KPA100 and KAT100). I'm offering this package for $585 + shipping ($603 if you pay via PayPal). Shipping should be about $15 or so, I'm guessing.

[Elecraft] [K2] headphone jack replacement tips?
I think I finally might get to replacing my failed headphone jack this weekend. Anyone have any tips for this little job? I recall that there are more than a few pins to desolder. Also, does it make sense to not put stress on the headphone jack in the future by plugging my headphones into the external speaker jack on the rear of the unit? My headphone cable is plenty long to reach there, and would rather not have to replace this again in the future--as it seems to be the case with many folks.

Re: [Elecraft] [K2] where there's the smell of smoke...
Hi Don, Thanks for the response. I received an off-list reply from another fellow who mentioned U6 on the KPA100 being an issue--but he said that I should be using the 3 conductor cable to connect the KPA100 to the USB-to-serial adapter. To clarify, I *am* using the adapter in the KPA100 manual (DB9 female on one end DB9 male on the other end) to connect to the USB-to-serial cable. In any case, I do agree that there is an issue related to the key or something being shorted to ground--but I don't think that keying the rig for the less than 2 minutes it took for me to run upstairs to get my headphones would've caused something to burn up (which is definitely what happened). I'm concerned about the fact that I saw a small spark when I plugged in the USB to my laptop and what ramifications that may have for the KPA100 unit or its circuitry related to the rig control/DB9. The key was definitely all the way in, though, I'll check that this afternoon during my son's nap. Thanks! -john On Sat, Jan 22, 2011 at 8:28 AM, Don Wilhelm w3...@embarqmail.com wrote: John, Maybe you are working on it too late :-) . If the keying stops when the key is removed, I would suspect the key and cable rather than the K2. To see if there is a key jack problem, plug a bare 3.5mm stereo plug into the jack. If your plug is only partly inserted, the dash contact in the key jack can be touching the shell - that will key the K2 with dashes momentarily until the plug is seated. As a side-note -- I have found several K2 owners who severely tighten the dress nut on the key jack (and the BNC jack as well). That really is not necessary and can damage the jack. Just tighten a little bit beyond finger tight. The nut holds neither the rear panel nor the jack in place, it is just there for appearance - just tight enough to keep the nut from backing itself off is sufficient. 73, Don W3FPR On 1/21/2011 10:25 PM, John Shadle wrote: First follow-up.

[Elecraft] [K2] no speaker audio (perhaps bad headphone jack?)
Hi all, I read through the archives and am wondering if I may have fallen prey to the bad headphone jack problem. I am able to hear just fine when I have my headphones plugged in, but get no audio out of the speaker when I remove the headphones. For the record, the speaker *did* work at one point...and I only started using the rig in October. Although I do pull the headphones out quite a bit since that's what I use to listen when I operate. This problem started a few weeks ago and I'm just now starting to think about trying to find a solution to it. I'm using the K2 with the KPA100 mounted on top. (At one point I had the KAT100/KPA100 in the same enclosure, but I have since moved to an SGC SG-239 at the base of my vertical and no longer need the KAT100 at this time.) Any tips for troubleshooting this problem?

[Elecraft] [K2] KDSP2 settings for CW
Hi all, I have been fiddling with the KDSP2 for a while and am trying to get my head around the settings for optimal CW reception. Yes, I know that's all subjective, but I'd be interested in hearing what folks are using for the denoiser settings (beta, decay, CW gain) as well as the CW filter gain. Default values are as follows: Denoiser * beta 89 * decay 71 * CW gain 0.00 dB CW filter * gain 0.00 dB Thanks! -john W4PAH __ 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] KDSP2 rave!
For some reason the noise level was higher than normal at my QTH last night on 40m. I struggled to pick out the signals at all--but heard a faint CQ around 7.117 MHz. I fiddled around with the stock crystal filters as well as the KDSP2's filters but was only able to hear the signal well after using the denoiser in the KDSP2's menu. I know that I still have a lot to learn about the KDSP2's functionality, but I just wanted to comment on what an amazing addition this is to an already excellent radio! With the KDSP2 denoiser engaged, W6RO (The Queen Mary, Long Beach, CA) was 339; otherwise, it was very unworkable. Also, I find that I like the soft filters better than the hard filters from the KDSP2. They seem more pleasing to the ear, in my opinion. Having finally finished my K2 in October (after a 2 1/2 year-long journey) and throwing away the mic for a while in order to hone my CW skills, I have been able to QSO with nearly 1/2 of the US states on 30m and 40m. My goal is to get all states confirmed by May so I can get my cards checked at RARSfest in Raleigh for WAS 40m CW.

[Elecraft] [K2] DE9 versus DB9, and how I can make a replacement cable
Hi, I completed the K2 and KAT100/KPA100 (in an EC2) project. Everything is playing well together, but there are some cable issues I'd like to resolve in order to make it less messy when I bring the radio out of the closet to operate. First of all, I plan on making a short (~4) jumper, which is required between the KPA100 and KAT100. Secondly, I'd like to construct a single connection between the main rig and the autotuner/amp. I already have the long Y cable built, but won't always be using computer control. Is it possible to get the DE9 shell, connectors, and the shielded wire from another source? Can I use DB9 connectors, or are they totally different from DE9's? I feel like this has been hashed out in the past (and perhaps in a manual), but I can't seem to find it. If it's just a matter of ordering a replacement cable and connectors from Elecraft, then fine; however, if I can pick up these parts locally (or through Mouser, Digikey, etc.) then I may opt for that. Thanks for your assistance in advance. -john W4PAH K2 #5684 __ 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] DE9 versus DB9, and how I can make a replacement cable
Right, Don. That's what I'm trying to replace is the cable from the KIO2 to the KPA100 (or KAT100). I have the Y cable constructed (PC -- K2 -- tuner/amp) but would like to make just a simple cable for when I don't need the computer control (e.g., K2 -- tuner/amp) and don't want all of that extra wire hanging around. Just looking to figure out where to get replacement parts. I suppose the DB-9 would be a find replacement. I looked at DigiKey a few minutes ago and they have those as well as backshell assemblies. The four-conductor cable only comes in rolls, as far as I can tell, so I might just steal a short length from the Y cable I already made. -john On Thu, Oct 28, 2010 at 9:49 AM, Don Wilhelm w3...@embarqmail.com wrote: John, I believe you have the KAT100-2, so you plug the KPA100 ribbon cable into the KAT100. That makes the connection for all signals that appear on the external cable. You only need one cable from the KIO2 - and it plugs into either the AUX I/O on the KAT100 or the KPA100, no need for both. You should not have to construct anything other than what you already have. Externally, the only connection between the KPA100 and the KAT100 is a short piece of coax and there should never be a need to remove it. Technically, the 9 pin D-sub connector is the DE-9, but is often mis-named as a DB-9. 73, Don W3FPR On 10/28/2010 9:25 AM, John Shadle wrote: Hi, I completed the K2 and KAT100/KPA100 (in an EC2) project.

[Elecraft] [K2] wobbly VFO knob, other knob issues
My K2 is very low use (just finished it a few weeks ago). When I turn the main VFO knob it wobbles a *lot*. It seems like it especially wobbles vertically, but also other directions as well. I tightened the screws (which were already tight, by the way) and that didn't help at all. Any ideas? Also, it seems like sometimes when I turn the knob a certain way for a long time (e.g., counterclockwise) it starts to get really tight and I have to turn it clockwise for it to ease up. Maybe I like to scan down a lot--but this seems kinda odd for the knob to get tight like this.

[Elecraft] [K2] S/N 5684 complete (finally!)
I finished my K2 a few weeks ago and have to first thank Don W3FPR for helping me with the alignment and final check-out. After bringing it back home, I went to work on the KAT100-2. That was a few evening/afternoon project, but it is done and it has been mated with KZ1X's old KPA100 very nicely (which is the only part of my K2 setup that I didn't build). Thanks to Don (again) for his assistance on this reflector for information on mating the KPA100 to the KAT100-2, and to the base K2. This past weekend I finally got the rig on the air for the first time. I have a small (slightly less than 1/4 wave on 17m) ground-plane vertical mounted on a fence post about 20' behind my townhome. Definitely not the most optimal of working conditions, but it's the best I can do for now. The KAT100-2 was able to make very good matches to my feedline and antenna on most of the bands I wanted to work. I spent a few hours over the course of this past weekend on 20m and 40m. On 20m SSB I picked up a little DX (Switzerland, Germany, Hungary) and a few special event stations and ragchews with folks in CO, MA, VT, MS, and WI. On 40m CW I was able to have a couple of short QSOs with folks in PA and IA before QSB and QRN got the best of us. What a lot of fun it is to use a rig that you built yourself--and have folks come back to you with excellent signal reports, too! You'll notice that my S/N is about 1500 back. I bought the base kit second-hand (eBay) from a fellow in late 2007/early 2008 and began work on the kit in March '08. Since then, my first son was born (June '08), I started a new job (September '08), we moved to a new home (March '09) and life got in the way of me completing the kit in a normal amount of time. Well, 2 1/2 years later I'm finally on the air! It definitely feels like an accomplishment. Thanks for a wonderful kit-building experience and now a wonderful operating experience. I know I have a lot to learn about all of the K2's features, but I feel well on my way...and I'm already thinking about what mods I want to make to the rig (and my station) next! 73 -john W4PAH Carrboro, NC __ 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] length of control cables between K2 and KAT100/KPA100
I'm almost done with the construction of my K2 twins (K2, KAT100/KPA100) and am about to construct the control cable for the K2 -- KAT100/KPA100 -- PC. The instructions from the KIO2 state that the length of the cable can be up to 15' (the total length included in the kit), but the KAT100 manual states that it should be 2' (between the K2 and the KAT100). The KAT100 instructions also state that A longer cable can also be used, but it will have to be tested to ensure that is is not subject to RF interference. Other conflicting information comes from the KIO2 manual (first page) which states that RS-232 interfaces are often significant sources of RFI but that the KIO2's serial interface provides an HF crystal oscillator (operating well outside of any ham band) to generate the negative driver voltage. So, which is it? ;-) I understand that the cable can pick up stray RF (I'm guessing that's why the KAT100 instructions state to make the cable as short as needed). Are the cables sufficiently shielded, or not? Should I consider purchasing other 4 conductor cables to replace the ones in these kits? As I sidenote, if anyone has information about using USB to serial converters for K2 rig control, please reply with that as well. I'm about to go searching through the archives now on that subject...

[Elecraft] [K2] sanity check for winding T1 and T2 on KSB2 module
I'm nearing the end of my K2 build, and am working on the KSB2 module at the moment. On page 11 of the most recent version of the manual (Rev E), it shows the secondary winding going against the grain of the primary winding. I really want to start with wire 2 on the same side of the toroid as wire 3. The picture shows wire 2 on the same side as wire 4. This makes winding more difficult and doesn't allow for me to go parallel to the primary winding. http://www.elecraft.com/manual/KSB2%20manual%20rev%20E.pdf Is this just a bad schematic, or does it matter what side of the core 1-2 are, relative to 3-4?

Re: [Elecraft] K2: current documentation on remoting KPA100/KAT100?
Yes, Don, that's what I'm planning on doing. I have a KPA100 already built, and have the EC2 with the larger front panel for the KAT100, which I'm planning to build the KAT100 into. So, basically I just need to install a BNC cable in the rear of the KAT100-2 and drop in the KPA100 into the KAT100-2? Are there other resistors, diodes, etc. that need to be changed in the KAT100 or the KPA100 (or the K2 RF board) to make this work? Or is it really that simple--adding a BNC connector and plugging the KAT100 into the KPA100? -john W4PAH On Mon, Sep 13, 2010 at 10:33 AM, Don Wilhelm w3...@embarqmail.com wrote: John, That guide is still good if you read the update notes. However, if you are mounting both the KAT100 and the KPA100 both in the same EC2 enclosure it is much easier. Order the KAT100-2, and you will find it has the 10 pin connector for the KPA100 control cable as well as the DC and antenna connectors - so all you need to do is plug the KPA100 to those connectors. When you make up the control cable indicated in the KAT100 manual, that one cable is then sufficient to bring the K2 control signals to the KPA100 and KAT100 combo, plug it either into the KAT100 or the KPA100. You will need a BNC to BNC cable between the K2 and the KAT100 AUX RF jack, and you will need a short PL259 to PL259 coax to connect from the KPA100 to KAT100 input. The KIO2 or a suitable substitute is needed in the K2. 73, Don W3FPR On 9/13/2010 10:08 AM, John Shadle wrote: I know of this one link. http://www.kk7p.com/k2kpa100.html Is this the most current/best guide for remoting the KPA100/KAT100?

[Elecraft] air travel with SLA batteries (was Re: OT Carrying radios on commercial flight)
Here is a relevant post I recently submitted to the QRP-L lists which may be of interest to folks here. For the record, no one asked me to turn anything on. -john W4PAH Hi all, I recently made a trip to Anchorage, AK for work and decided to carry on two 17Ah SLA (sealed lead-acid) batteries to support my operations. Some folks on the list said don't risk it and ship them ahead of time. Others said, tape the terminals and pack them in your carry-on. Since I had done this in the past (with 7Ah batteries) I decided to risk it again. I found a web page on the TSA's site which was helpful and printed it out to carry with me. http://www.tsa.gov/travelers/airtravel/assistant/batteries.shtm This ultimately proved helpful during my departure from RDU (Raleigh Durham Airport) on Saturday morning. The TSA agent (who had 1 stripe on his shoulder-boards) told me that unless I had an electric wheelchair, I wasn't allowed to carry on these batteries. I explained to him that I had taped the terminals and packed them in bubble-wrap to protect them from damage. I showed him the web page which I had printed out which stated that you must Place each battery in its own protective case, plastic bag, or package, or place tape across the battery's contacts to isolate terminals. Isolating terminals prevents short-circuiting. I had followed all of the rules. He brought over his supervisor who had three stripes on her shoulder boards (I have no idea how many you can have, but I saw folks with one, two, and three). She read my printout and looked in a manual she had. After reading it a few minutes she let me pass. I thanked the one-striper for his patience (and tried not to do so in a sarcastic or snarky way), and re-packed my bag. Success! On the way back from my trip, I was again pulled aside and another one-striper unpacked my carry-on and ran everything through again. He said, Oh, you must be an amateur radio operator. We had a short conversation. He was impressed with the radios and stuff I had. ;-) No questions at all, he just wanted to make sure the SLA batteries weren't concealing something in the x-ray image that could've been below or above them in the bag. So, I think in the future the lesson learned is to be prepared by following the rules for protecting your batteries from the TSA's web site (tape over terminals to prevent a short, pack the batteries in bubble wrap or a bubble-wrap envelope), printing out the page from the TSA's web site, and be patient as you go through all levels of TSA employees until you reach someone who actually knows the rules. 73 -john W4PAH P.S. I wasn't able to do much operating at all while in Alaska, unfortunately.

[Elecraft] OT: sideband filtering (USB v. LSB)
Hi all, Please forgive me for this non-Elecraft intrusion. I'm hoping that someone can help me out with a question about modifying rigs to operate on the opposite sideband. Please continue reading below for my reason why... I'm trying to modify Dave Benson's PSK-20 rig to operate on USB (it currently operates on LSB, even though it is a 20m rig for PSK31). I want to replace the 5.07MHz LO with a DDS module to allow for tuning across the entire 20m ham band. I emailed Dave about this and he responded that I suspect your talking about going anywhere in the band - a DDS-based signal in place of that oscillator would let you go anywhere in the band. That's exactly what I'm hoping for. He gave me another hint in the following sentence: ...you need to pull the 9MHz LO to the other side of the filter passband so that the rig is operating on the (standard) upper sideband on 20m. The theory of operation and the schematic may be found on pages 6-9 here: http://smallwonderlabs.com/PSK20_Manual.pdf I'm no RF engineer, but just a kit builder who is trying to understand how his radios work. ;-) The manual states (on page 7) that Single-sideband filtering is performed by a second filter comprising Y7-Y10 and related capacitors. After passing through the transmit IF filter comprising Y7-10 and related components, the signal has been reduced to a 9 MHz SSB signal. It's output drives 2nd mixer U7. This mixer is also driven by a signal from the 5.07 MHz LO, Colpitts oscillator Q9 and associated components. From this, I am guessing that: - Y7-Y10 and related capacitors reject the USB signal - Something must change (the value of the capacitors C19-C23?) to allow for the LSB signal to be rejected and the USB signal to pass I'm not sure where to figure out how to pass the USB signal, though. That's where I'm getting stumped. Also, I'm not sure exactly where to place the outputs of the DDS signal generator. This will replace the 5.07MHz LO (page 9, middle of page, right-hand side). Should I just not install the crystal (Y6) and put the output of the DDS in its place, or should I remove all components related to the 5.07MHz LO and have the input of the DDS at R48/R49? If there are other places I might be passing my questions to, please let me know. Sorry again for the intrusion. 73 -john W4PAH __ 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

Hi all, I'm trying to get my K2 finished soon and am hoping to work on the KSB2 module this weekend and early next week before some work/leisure travel to California.
