Re: [Elecraft] VFO IND in the KX3?

[Elecraft] GREAT service
Just a public note to thank the guys at Elecraft for their legendary service. I recently requested a new 2nd VFO knob to replace the one that had cracked on my newly acquired K3.

[Elecraft] Anyone have a beginners guide to utilizing roofing filters on the KX3?
Hi, I've been using primarily digital modes on my KX3, but have started moving into SSB as well. I've got the roofing filters installed in my KX3, and have used them a little when the contesting has gotten out of hand and picking out a signal has been difficult. Aside from that, I'm curious how people are using roofing filters/if anybody has written up something on when/how to use these kinds of filters. I'm learning by experimentation (this is why I'm an amateur radio enthusiast) but would love to have some starting points to run with. Now that I have the PX3, I've been experimenting with adjusting pbt i/ii to a narrow bandwidth for psk31, but haven't had a lot of opportunity to see how much difference/if any when it comes to that kind of operation. I'm primarily operating digital (Olivia/Contestia when I can; mainly psk31 due to popularity) but have started to branch into SSB. It seems like I may never use these filters on SSB, but I thought I might ask when it would be useful/how to utilize these in case I'm missing something. CW is on the list, and from what I can tell, the filters might be well suited for that, I just need to learn to hear/speak code much better before I can take advantage of that.

[Elecraft] PSK31 on KX3/PX3 + ref/scale on PX3
When using the PX3 panadapter, should I be attempting to select the center of a psk31 communication on the waterfall, or picking the low end or high end depending on band? My text decode has been variable so far, and I've not been able to figure out why. Sometimes, I'm tuned at the center of the transmission, and I get a lot of 'E' characters, sometimes I get full decode. Sometimes I tune at the bottom of the transmission on 20m, and get a clean decode, sometimes nothing. I haven't figured out what I'm doing right/wrong that drives clean decoding. I'm also unsure how to adjust ref/scale appropriately. If anybody has any tips/rules of thumb, they would be very much appreciated. You'll have to excuse my ignorance, I'm a new operator and have spent most of my time building/working on new antennas. I'm just now getting around to optimizing the transceiver side of things.

[Elecraft] Digital modes other than PSK31
Are there any plans to implement Olivia/Contestia into the KX3? I'm finding these digital modes are wonderful when using sub-optimal antennas or in a noisy location to conduct rag-chews, and I've love to be able to utilize these when out camping to talk with friends since I'm running QRP, without a computer. It would be amazing to have this capability built-in (one of the reasons I'm learning code is to ditch the laptop). Being able to converse even below the noise floor is mind-boggling to me, and I'd love to see this implementing in my radio (KX3) or the PX3.

Re: [Elecraft] VFO IND in the KX3?
Hi Dave, To resurrect a technical description about LF-band receive I posted earlier this year: * * * The KX3 does not have filtering specifically for the lower portion of the AM radio band. It is intended primarily as a ham-band transceiver, and covers nearly the entire SWL range. But to completely eliminate low AM-band 3rd-overtone LO images such as the one you're hearing would require at least two and possibly three more filters (more on that below). Complicating this is the high-pass filter in the T/R switch, which is intended to protect the PIN diodes from very strong signals below 1 MHz or so. This attenuates low-AM-band signals. (To quote the KX3 product brochure on our web site: ...also covers 0.31 - 1.5 MHz with reduced sensitivity….) The KXAT3 ATU provides some additional filtering for the lower AM range when correctly configured. But at 500 kHz, the LO still isn't filtered enough to eliminate strong signals. * * * The IC706mkIIG probably uses a keying relay rather than PIN diodes in the main T/R path. 73, Wayne N6KR On Oct 27, 2014, at 1:47 AM, Dave elecr...@g4fre.com wrote: I found similar at GW0FRE.

Re: [Elecraft] Now which mic can I use.
Let me add my 2 cents. I heard so much crap audio this weekend, that all I can recommend is that you use a Mic element purpose designed for the job of SSB QRP communications. I have recordings of good and bad examples that I will assemble into something useful at some point. I heard guys with big wide signals that I could not understand who were running lots of power. I also worked many QRP guys with amazing audio that was correctly shaped for SSB. Don't kid yourself, that $2 computer mic, while it sounds ok locally doesn't cut it when you need your signal to be understood. This is not about FM full range audio. This is about being heard and understood. Bob Heil spent lots of time designing the right mic element for SSB communications. He did this with input from Bell Labs. Leo Laporte did a great interview with Bob where he describes why he did it. Since you asked, my choice every time is the HC5 with the right cables. Keep a close eye on your ALC settings too. Your KX3 will work just fine and you will be heard. 73, Mike va3mw On Sun, Oct 26, 2014 at 9:08 PM, Don Wilhelm w3...@embarqmail.com wrote: Tim, You can use many headsets and microphones with the KX3 - *IF* you are willing to build an adapter.

Computer type microphones and headsets can be made to work, but because the tip and ring are connected together, there is some special considerations to be had when choosing the bias - they work OK with bias turned off, but then will be using the source for digital voltage in the K3 to bias the microphone which can cause noise in the signal. While it will work, a proper adapter will provide better quality results. That is why I built the adapter for my CM500. 73, Don W3FPR On 10/26/2014 5:14 PM, Timothy Gordish wrote: I have several microphones on hand and wondering if any will work with my soon to be order KX3.

I have my homebrew adapter for the CM500 headset that works just fine, but if you are not able/willing to build your own adapter, order the Elecraft MH3 microphone - it works just fine. Computer type microphones and headsets can be made to work, but because the tip and ring are connected together, there is some special considerations to be had when choosing the bias - they work OK with bias turned off, but then will be using the source for digital voltage in the K3 to bias the microphone which can cause noise in the signal. While it will work, a proper adapter will provide better quality results. That is why I built the adapter for my CM500. 73, Don W3FPR On 10/26/2014 5:14 PM, Timothy Gordish wrote: I have several microphones on hand and wondering if any will work with my soon to be order KX3. My preference is a Heil Pro-Set Plus which has two crystal elements and a phase reverse switch. By far the most comfortable headset I have ever use. Can I use these with an appropriate adapter? Then I have a Yaesu HT speaker mic with the correct 4 conductor connector used with a VX-5. Then I have a headset with the same connector which I used with a HP netbook. Cheep but sufficient. Will any of these work, or should I just order the Elecraft hand mike? __ 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 va...@portcredit.net __ 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 n...@arrl.net __ 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] Now which mic can I use.
Yes, there are a lot of bad SSB signals on the air - excessive compression and excessive mic gain leading to splatter and unintelligible signals. With the K3 and KX3 TX EQ, there is no need to be particular about the microphone. The K3 and KX3 have the means to make most any microphone sound good on the air. For communications quality, set the first two bands of the TX EQ to minimum to reduce the bass response. reduce the 3rd band by 6 to 8 dB. If your microphone does not have the high end boost, set the upper two bands to +1 to +3 dB and you will have good sounding communications audio. Yes, I do have a microphone with the Heil HC5 element, and I have an Elecraft MH2, and I have an Astatic D104 with an FET in the base to change it to a low impedance. I typically use the D104 with no rise in the high end (because it is present in the mic element), but I do cut the low end as I have indicated. Those lows add nothing to the communications effectiveness and only burn up power. On the K3, you can use TX TEST and record the monitor to see how you will sound on the air. When I do use my CM-500, I boost the two high bands to +3 dB, but the other mics already have the high end boost built in. Unfortunately, the Heil elements are no longer available as separate products and Heil has settled on the low output HC6 as his element of choice for his microphones (too much bass for my tastes). Besides, Heil products are grossly overpriced IMHO, and I do not favor ESSB. 73, Don W3FPR On 10/27/2014 4:05 PM, Michael Walker wrote: Let me add my 2 cents.

Re: [Elecraft] ACOM 2000A and Elecraft K3
Bill, Setting AUTOINF to 1 the K3 will report any changes over the RS-232 bus - this is not polling - it is information send by the K3 without any polling requests. I don't know the ACOM 2000A capabilities, but if it does poll the K3 for information, the proper setting for the K3 is AUTOINF = nor. Yes, when a logging program is involved, the logger will poll the K3 for information, and the ACOM may 'listen in' and respond to band changes, etc. In that case, the K3 should be set to AUTOINF = NOR. 73, Don W3FPR On 10/27/2014 3:13 PM, Bill Turner wrote: I think I have figured out the connection issues when using a K3 with an ACOM 2000A. I wrote up the following mini-tutorial to try to clarify what is, to me, a confusing situation. Please read it and let me know if I have made any errors and whether you find it helpful. If you find it helpful, feel free to copy and distribute any way you wish. Thank you, 73, Bill W6WRT +++ When operating an ACOM 2000A with an Elecraft K3, there are two possible modes of frequency control. Each mode requires a different cable. When a PC is NOT connected: Use a cable like that shown in figure 7.6 of the ACOM 2000A manual. You should set the K3 AUTOINF menu option to 1. In this mode the 2000A will poll the K3 for band data and will change bands accordingly. The K3 will also send band data when you manually change bands on the K3. When a PC IS connected: Use the cable shown in figure 7.2 in the 2000A manual. You should set the K3 AUTOINF menu option to nor. Note that this cable does NOT have the TXD wire going to the ACOM 2000A, but it does have the TXD wire running between the legs of the Y connector. This cable can be either a single cable terminating in two DB-9 connectors or it can be a single cable with a Y adaptor connected at the DB-9 end. In either case, it must be the electrical equivalent of figure 7.2. In this mode, the ACOM 2000A gets band data information ONLY from the logging program, not from the K3. If you close the logging program, the ACOM 2000A will NOT follow band changes from the K3. You can still do band changes by sending a dit as explained in the ACOM 2000A manual. __ 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 w3...@embarqmail.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 Message delivered to arch...@mail-archive.com
[Elecraft] K30 mini ticking sound
I have up dated my K3 to the latest Beta FW to cure the ticking sounds when using it with the K30 mini under remote control. The ticking still occurs, and I assume that I also have to up date the FW in the K30 mini as well? How do you connect the K30 mini to the K3 util to allow for FW up dates. My K3 util dose not see my K3 0 mini using the supplied USB cable.

Re: [Elecraft] Now which mic can I use.
I agree, though the CM500 isn’t that bad for backpacking, and I go lightweight. A KX3 with batteries is very close to one kilogram. A wire antenna adds another 100-150g. The CM500 is 300g. Some earbuds (haven’t weighed them) and an Elecraft MH3 (138g) are lighter, but the difference isn’t a back-breaker. Maybe 1300g vs 1400g, about a 3.5 oz. difference. wunder K6WRU CM87wj http://observer.wunderwood.org/ On Oct 27, 2014, at 8:59 PM, Jim Brown j...@audiosystemsgroup.com wrote: On 10/27/2014 1:05 PM, Michael Walker wrote: I heard so much crap audio this weekend, Didn't we all. that all I can recommend is that you use a Mic element purpose designed for the job of SSB QRP communications.
