Re: [Elecraft] KX3 Battery Charging Question
Correct. You can set the time on the charge too, using the VFO A dial. Charge rate runs about 200 mA, so in general a 12 hour charge works for fully discharged batteries. It's one of those YMMV things. matt W6NIA On Thu, 10 Jan 2013 00:17:06 -0600, you wrote: >Hello, all - > >I installed the KXBC3 and charged up the batteries.

[Elecraft] KX3 Battery Charging Question
Hello, all - I installed the KXBC3 and charged up the batteries. It's all working well. My understanding from reading the manual is that the KXBC3 does not automatically charge the batteries. For example, if you use the KX3 on battery power for a few hours and then plug it into the power supply in the shack, the batteries will not be automatically be topped off, but you have to go to the bat chg menu item and initiate a charge. Is that correct?

Re: [Elecraft] K3 Keyer Cable Connection Problem
I resumed troubleshooting by going back to the basics. First, I cut off the connectors on one end of the Bencher factory cable. Instead of using the Bencher keyer, I then connected the red and white wires to a post on my Vibroplex Original keyer, and the black wire to another post on this keyer. Using the 1/4" adapter, I inserted the plug into the Keyer port on the K3. Instant success! It worked perfectly. Yet another reason to keep a reliable bug in the shack. Next, I created a second cable for the Bencher keyer by reworking a factory made patch cable with 1/4" plugs. While doing that I discovered the sources of trouble I had previously with this keyer. The other cable had not been securely attached to ground, and the keyer was shipped from the factory with both paddles in contact with their posts. If I had to do it over again, I would make my own cable from another patch cable. In fact, that is exactly what I plan to do soon, because I recently received a new Bencher ST-1 keyer for my collection.

Re: [Elecraft] K3 and HRD
Hi Rick, The TUNE button properly sets the KAT3 tuner tuning operation. I had to make a new CAT command to change it to an actual TUNE (send a carrier) to tickle the KAT500 into knowing what band portion I was on or for retuning. Um, SWH16? I'd have to look again. Unless I've totally missed something in V6b2, having an integrated terminal program (make it part of DM780?) for the K3 native PSK and FSK modes would be REALLY useful instead of relying on Data A mode or other external wiring. It could also be used to manually enter in commands for macro testing and it would play well with other brands of similar abilities. I also created a button and band display for 6M. Another row (or three) of buttons would be useful for remote ops since it's easy to run out of buttons. I've retasked some of them for remote operations. I've also noted that some buttons do not light up when active. The metering does not show the SWR in tune/tx mode(s) nor is it very responsive to quick changes. This also occurs when operating local so it isn't necessarily a polling frequency or latency issue that one would expect over a network. Thanks!

Re: [Elecraft] [KX3] Transverter Band TX output
More info: I have the ATU installed in the KX3. Even with the KX3 directly connected to a good 50 ohm load, running an autotune on the XV bands (28 MHz) causes lots of relay chatter in the radio, and a displayed SWR of 25.4 that does not change. On the other bands (including 28 MHz) it immediately goes to 1.0. Setting the ATU to bypass still does not get RF output on the XV bands. The current draw key down at 0.1 watt is about 0.43 A on the XV bands, and about .55 on the HF bands where there is output. Has the KX3 firmware caught up with the XV bands? I'm using V1.30. 73 - Jim K8MR In a message dated 1/8/2013 10:15:12 P.M. Eastern Standard Time, jimk...@aol.com writes: I'm working at getting my DEM transverters interfaced to the KX3.

When I use 28 MHz with the power set at 0.1W I'm showing about 350 mW (4V RMS).

Re: [Elecraft] Elecraft Digest, Vol 105, Issue 14
Yep. Ran in the RTTY RoundUp this last weekend. My setup is "maximally minimalist" ... two RS stereo cables between LINE IN/OUT on the K3 and LINE OUT/IN on the laptop running N1MM+MMTTY. I have the K3 in AFSK, PITCH=915Hz [I can't hear anything above about 1200 anyway]. Set 915Hz in MMTTY. If your computer has only a MIC input, you'll probably need an attenuator feeding it, you can make one from a couple of resistors, or you can get one from Radio Shack. This same thing works with the K2, you do need the SSB adapter and the attenuator into the MIC jack. I used that for several years before getting the K3. 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org On 1/9/2013 8:32 AM, KR9A wrote: I am wondering if anyone has used the k3 in any rtty contests and what their menu settings are for the radio, thoughts comments, expectations etc as opposed to all the greatness I hear on the y 5k reflector.

[Elecraft] KPA RFI problem
First, a thank you to everyone who has taken an interest and provided information on my problem. In an attempt to quantify the problem, I sent Jack W6FB a copy of the fault dump on the KPA500. I sent Dick K6KR, the trace he requested from the KAT500. I also sent him the information he requested, from the KAT500. If those prove helpful, I will share the information. Tuning solution at 25 watts on 24.968MHz capacitance 104 pf inductance 340 nH vswr 1.17 bypass vswr 6.17 capacitors on antenna side unchecked. While going through the trace exercise for Dick, I set the K3 to produce a dead carrier and then slowly increased the drive from 10 watts to the point where the amp showed 500 watts output with no fault. Thinking the gods had smiled on me, I switched to sub, set the power to give 400 watts, started to call CQ and the amp faulted. I did not capture this fault so I started another trace and slowly increases the drive power while calling CQ, and got to 500 watts peak output with no fault. I then set the drive to give 400 watts peak output, started a trace and began calling CQ. The amp faulted. I repeated the dead carrier sequence and let it sit key down for ten seconds. No fault. I am not sure if this is useful information or just a confirmation that the faults are unpredictable.

Re: [Elecraft] [KX3] 160-80 meter mod?
John, The 160/80 meter mod that improves IMD dynamic range requires replacing a total of four parts in the T/R switching and one of the BP filters. The mod would not be overly difficult for someone proficient with SMD rework but I wouldn't recommend it for someone who isn't. To answer your question, trying to break off the existing parts would most likely damage the board. The areas are also pretty dense, so soldering iron access is a bit tricky in a couple spots. 73, Rich AC7MA On 01/09/2013 06:12 AM, John Fritze wrote: Can anyone who has done the 160/80 meter LP filter mod tell me if there are parts now on the pads on the circuit board?

Re: [Elecraft] PSK31 on K3/100
Because ultimately it is simpler and keeps extraneous noises off of the air such as system sounds. It also means that you can set/forget audio settings once properly set. If you choose to use a soundcard, a cheap USB soundcard is just fine. Of course, PSK is inherent in the K3 abilities so a simple terminal program is sufficient too. As for 40M Ray, if it is manageable, you might want to listen in the early morning just before your local sunrise (+2-3 hours), it's been a LOT of fun on long path lately (all the way up to 10M actually, I worked Oman and UAE on 10M last week, long path). 73, Rick wa6nhc -Original Message- From: Ray Coles Ray, Why do you want an external interface?

[Elecraft] K3 RTTY
Used my K3/P3/KPA500/KAT500 combo this past weekend in the RTTY Roundup. I use a Numark USB soundcard from Amazon for about $30 and it worked great. This is one of the soundcards recommended by Jim Brown, K9YC. Setup is easy just follow the instructions in the K3 manual for AFSK. The only thing I do is to set the Numark volume control to max and put a bit of tape over it to keep it from being changed. Used N1MM for the software. Ran 500w without any issues. It was my first real attempt at any RTTY other than an extremely rare QSO. Worked fine without any problems. 73 jim ab3cv __ 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 RTTY contest
I used mine in this weekend's ARRL Round-Up in conjunction with N1MM (using the FLDIGI modem) and a sound card. The system, of which the K3 is more or less the RF "front end", worked great. It's nice to be able to pick out an S3 multiplier station next (next-next) to an S9 +30 "honker" with no AGC pumping, de-sense, etc.. I owned a Flex 5K until recently (still pictured on my QRZ page, have to update that) and I have to say the K3-based combination works better in terms of RF performance and interoperability with contesting gear. I'm no K3LR, so take my experience with a grain of salt...but it works for me. 73, Mike Alexander - N8MSA amsct...@comcast.net - Original Message - From: "barry whittemore" To: elecraft@mailman.qth.net Sent: Wednesday, January 9, 2013 12:45:22 PM Subject: Re: [Elecraft] K3 RTTY contest Bill, I use RTTY often in contests and find it incredibly easy to use.

Re: [Elecraft] KPA500 RFI problem
Dave, Most likely a tuner is being used. If the balun failed one might not notice that since one generally tunes to min SWR. Unless one recognizes something changed, one wouldn't know it failed. This is especially true for auto tuners. This "not knowing it failed" is wide spread for bead baluns-- although this isn't the case here. 73 de Brian/K3KO On 1/9/2013 17:26, David Gilbert wrote: If that balun had overheated and become ruined on 12m it almost certainly would have affected other bands as well.

[Elecraft] K3 line out
Dear Jim: Something is screwy. I run the same sound card, but usually run around level 10 on the k3 to put the input in the middle of the Tascam input level knob range. Make sure you are using the right input jack on the Tascam, and the line out on the k3. When I used an internal sound card on a laptop with a too-sensitive mic input, I used a cheap Radio Shack headphone cable with an inline volume control. I ran that on EME for years and it worked like a charm. 73, Eric WD6DBM Sent from the metering jack on my Heathkit Twoer __ 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] Broadcast band interference [KX3}]
While the rusty bolt syndrome is real, what is being discussed here is likely what is called am broadcast bleed through. This is a consequence of a direct conversion receiver and as I understand it is second order issue in the receivers front end, which basically makes it act as a detector to AM signals.It can be eliminated by using the 8 kHz offset in the kx3, or by filtering out the broadcast station before it gets to the antenna. If what you hear is resulting from an external mix (like from a rusty bolt) you will be able to tune away from it, since it will be on a discrete frequency, (although it might be wide, since it could have a harmonic aspect). If it is am bleed through it will be 'every where' since it is in effect getting into the radios IF which is not tunable (well it is if you use the 8 kHz offset). I'm sure not an RF or receiver designer but did find a lot of references about this on the web. The first ham SDRs had real issues with this. The kx3 seems to be much, much better. Mark.

Re: [Elecraft] Broadcast band interference [KX3}]
Gary, Direct detection of AM signals is inherent problem with zero IF SDR. The best solution is the use of RX SHIFT. You can possibly use high Q filter at the input of the radio if you know the frequency of the interfering AM station and if it is only one such a station. But it is hardly practical solution. When RX shift is enabled you do lose narrow roofing but 15 kHz roofing is still in place. Without roofing filter the radio still has more then 90 db of IMD dynamic range which is more then enough in 99.9% of cases. Think of those using Yaesu and Icom rigs with DR of less then 80db and still winning contests. More valuable feature which is lost with RX shift engaged is DUAL RX. Yet Wayne promised, we will get DUAL RX with RX SHIFT in future firmware releases. 73, Igor UA9CDC - Original Message - From: "Gary Auchard" To: Sent: Wednesday, January 09, 2013 9:15 PM Subject: Re: [Elecraft] Broadcast band interference [KX3}] I posted a question concerning an issue with broadcast band interference on my KX3 and received several good replys.

Re: [Elecraft] Broadcast band interference [KX3}]
Somewhere in the back of my head is a recollection of issues surrounding spurious signals caused by the mixing of strong signals in things like corroded gutter joints etc. If there is a strong signal present from the AM station at all times then the other signal varying in strength might cause his fade in and out issue. Can some who is a real engineer tell me if this makes sense or have I been smoking green leafy stuff?

Re: [Elecraft] Elecraft Digest, Vol 105, Issue 14
I am wondering if anyone has used the k3 in any rtty contests and what their menu settings are for the radio, thoughts comments, expectations etc as opposed to all the greatness I hear on the y 5k reflector. I know the K3 is a great radio but I don't seem to read too many operator comments on its greatness.. thanks all.

Re: [Elecraft] K3 Remote VFO tuning control
I've been following this thread but have not responded since my impression of the original request was for a self-contained tuning knob that did not require use of external software and an associated computer. I agree with Ian's proposal that, although it is not a standalone solution, the Shuttle Pro is a device that, in conjunction with appropriate software, offers a lot of functionality. I use the Shuttle Pro with my mobile contest logger (CQ/X) to control multiple functions on the K3 in my mobile installation wherein the K3 is in the back of the SUV and the operator is in the front passenger seat. Details on this application of the Shuttle Pro can be found by following the Elecraft links on the Radios page of my website (www.no5w.com). I'm happy to discuss the details if there are questions. 73/Chuck/NO5W __ 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] Broadcast band interference [KX3}]
I posted a question concerning an issue with broadcast band interference on my KX3 and received several good replys. Here's more info on this issue.there is a local AM broadcast station about 8 miles away but that is not the one I'm hearing. It's sounding like a Shortwave AM broadcast from some religious station. Using the RX SHFT as suggested by one person replying is not a viable option. When you do that it disables the Roofing Filter option which I need usually for copying CW signals where I'm having the problem. I do have the antenna tuner installed and tuned to the band where I'm working but I'm still getting the problem. The signal does vary up and down in strength so I'm sure it's a Shortwave signal causing the problem. I can live with the problem most of the time but I would hope Elecraft could provide an answer to this issue. How about it Eric or Wayne? Any comments from your end?

Re: [Elecraft] KPA500 RFI problem
Sounds like the 4:1 balun may be overheating on 12M. Chances are if you've been doing this for a bit, it's ruined. Heat anneals the core and changes it's electrical properties for the worse. Heat may have cracked it. Now whether a 4:1 balun is the thing to use is another issue. You don't say how long your open wire line is so it is impossible to estimate the impedance seen by the balun. Here are the approximate antenna feedpoint impedances for a 120' double 50' up. 80M 47 -j188 SWR=17:1 4:1 balun at antenna feedpoint makes situation worse 40M 1724 +j1869 SWR =75:1 4:1 balun at antenna helps 20M 415 + j880 SWR =45:1 4:1 balun at antenna helps 15M 186+281jSWR =13:1 4:1 balun at antenna helps 12M 1293-155j SWR =63:1 4:1 balun at antenna helps 10M 122.4-j100 SWR =4:14:1 balun at antenna helps It is clear that 12M may be close to the worst of the lot If one knew the electrical properties and length of the ladder line, one can do the impedance transformations and determine just what impedances the balun sees. One may end up with entirely different conclusions from above. The G5RV is an example of a "doublet" antenna where the ladder line length is pruned to find an acceptable match on several bands. 73 de Brian/K3KO On 1/9/2013 13:41, Jim Miller wrote: I strongly suspect you have a common mode problem.

[Elecraft] Odd subrx problem
This has happened enough to raise it as an issue. I have a SDR on the subrx IF. I operate mostly CW. The SDR is set so that frequencies agree at zero beat on CW. A/B VFO's are linked for normal everyday operation. I use ROCKY for everyday use and SKIMMER for contests. If I change mode to say SSB, the SDR/panadapter display remains proper. However when I change the mode back to CW, the subrx's display is displaced from where it should be. It takes an A->>B ALL to bring it back to normal. Anybody else see this? It appears to be some sort of bug. Since it is evident in both ROCKY and SKIMMER, I'm suspecting the K3. ROCKY is not linked at all to the K3 and knows nothing about mode. 73 de Brian/K3KO - No virus found in this message.

Re: [Elecraft] My K2 is now Transmitting 15W on 80M CW but power drops off as I go up bands
Cliff, There are two areas of the K2 transmit chain that have frequency dependent components. The Transmit Buffer and the feedback loops from collector to base of Q5 and Q6. Check the soldering for the components connected to RF Board U9, especially R94 and C150 on the bottom of the board. Also reflow the soldering of the components around Q5 and Q6. One other thing to check is the value and soldering of R98 on the bottom of the board - it should be 270 ohms. 73, Don W3FPR On 1/9/2013 1:39 AM, Clifford Hynds wrote: This is strange,, My K2 is now Transmitting Max 15W on 80M CW but power drops off as I go up bands 6W on 40M about 3W on 30 and not much at all on the other bands.

No warranty or guarantee can be offered for the use of the software, nor any responsibility for anything going wrong.

I'd be interested in comments on the functionality and usefulness of it. 73, Iain M0PCB On 08/01/2013 17:21, Iain Kelly wrote: All, I only caught this thread partway through, and the recent Digest emails have been quite lengthy so I don't even know who was asking originally. However I do have my own solution to this problem. I originally wanted something to be able to fire off the DVR without using a contest logger, currently Win-Test and the LUA scripts available. Sadly for the local RSGB VHF contests I use another program that doesn't have rig control. I found a program called K-Keys by KE3C which allows up to 10 macros to be defined and assigned to keyboard short-cuts. I then found KTune by G4ILO and that got me thinking about an off-board controller for tuning and custom macros. I came across the ShuttlePROv2 which is a video-editing tool and has a jog wheel, fast-fwd and rev control and a number of buttons. These actions can all be assigned to keystrokes in the driver application. However, I found that although KTune worked well with this, K-Keys wasn't able to pick up the keystrokes. The ShuttlePRO is definitely generating the correct keys, so I had a problem after having spent £70 on the controller. A friend of mine suggested I ought to write something myself using AutoIt - a windows scripting tool. Based on an example file and a DLL someone had written for it I managed to cobble together an application that sits in the background and controls the K3 nicely through LP_Bridge. I've implemented most of the macros I want to do, mode switching, amp control and message memories as well as variable rate tuning and jog wheel for VFO A and stepped tuning of VFOB and automatic 2kHz CW split. I am planning on making the SSB mode change smart by reading the frequency from the rig and setting LSB and USB depending on the answer. I also want to make the 'split' intelligent for CW and SSB as well. I'm also thinking about adding in a GUI to configure the macros and com port settings, but I'm not able to promise I can do that any time soon as the program is working for me as it stands. I'm not a software engineer, the settings etc are all hard coded, but I was able to generate an executable that I have in my start-up folder. I only wrote it on Sunday 6th Jan so it's not finished but certainly working in I guess an alpha test. If anyone would like a look at the script I can send it to them, I've not had chance to get it onto my website yet (www.m0pcb.co.uk) but hoping to do that today. I am not really willing to release it as a working program yet as it's very much a prototype at the moment. If anyone is interested it might be best to talk off-line as I often don't get chance to read through the daily digest emails in much detail and I may miss things. 73, Iain M0PCB __ 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 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
