Re: [Elecraft] KX3 Utility & Windows 8.1
Thanks Mark, well the success got better as I was able to get my SCS Pactor modems, DSP Tracker, SignaLink Interface etc and all the software going too, so my KX3 is truly a multi mode radio now, that is very portable. 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 > On 29 Mar 2014, at 3:47 pm, Mark Petiford wrote: > > > RE: "Great, I have actually achieved something for the day!" > > Jack, > > Excellent.

[Elecraft] KX3 Utility & Windows 8.1
Hi Everyone, I never seem to have much to contribute to this list, but this may help someone Managed to get my new Dell Venue 8 tablet with WIN8.1 going with the KX3 utility. Whilst the screen on the unit is only 8" it's a workable setup and being able to manage my KX3 without lugging a laptop around, is a big bonus. First thing I did was use it to save my configuration :-) Now, I have no fear of ever having to do an EEINIT in the field! Plus I have all the other benefits of the KX3 utility. I just used the standard KX3USB cable with a USB OTG adapter cable that I ratted out of an older Android Tablet kit I had. Took a few port tests to register COM3 in the utility (COM1 no go) and it's all up and running. Great, I have actually achieved something for the day! 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 __ 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] KX3 OSC Temp And Freq Drift Relationship?
Thanks everyone for the ideas.I have the XG50 for the job. Doing the Temp Comp routine hopefully will improve the reliability of decoding PSK31 directly with the KX3 and my HCT.

[Elecraft] KX3 OSC Temp And Freq Drift Relationship?
Tonight I have been experimenting on PSK31 at 3 watts and 5 watts. In my shack the OSC Temp is about 38 deg and transmitting my CQ call about every 60 seconds @ 3 watts takes the OSC Temp to 39 deg, on RX it drops back to 38 deg. At 5 watts it goes up to 41 deg, but immediately settles back to 38 deg. My question is, what would the estimated frequency change be, per degree of OSC Temp change? I am trying to work out the total freq shift between the start and the end of my PSK31 transmission. Now, I have not done the OSC temp compensation routine to my radio. Trying not to go down this road in case I make a hash of it :-) In closing, I will not be using WSPR or JT65 etc with this radio. 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 __ 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] Multiband end-fed dipole with KX1
Paul, I also use these for portable work, you may need to carry a couple of antennas, or make up some half wave length wires for bands other than 10/20/40. On their QRP antenna you remove the tri-band wire and put on the wire of your choice, to work other bands.

Re: [Elecraft] A confession
Charlie, You must admit it's been fun along the way :-). I have Icoms Yeasus etc scattered around here everywhere, about 10 of them and they have all given me pleasure at some time or another and still do. I got an SG2020 when they came out...thought it was the best thing since sliced bread! It's died more times than I have had hot dinners...but I still have it and does currently work! And then I drank the Elecraft Kool Aid...the taste was mysterious, but I grew to like it very much. I look forward to new software releases all the time now..when I load them up I get that new radio feeling every time..yet I still have the same hardware :-) Never look to the past, always look to the future and your next Elecraft purchase! 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 > On 10 Feb 2014, at 6:40 am, "Charlie T, K3ICH" wrote: > > You want product obsolesance.?...How about the Icom's progression of "new & > improved" starting with the IC-756, followed by the IC-756PRO, IC-756PRO II, > IC-756PRO III , and finally (?) the IC-7600. > > I'll admit, they suckered ME into ithad 'em all. > > Got a K3/P3/VGA now. > > 73, Charlie k3ICH > > > - Original Message - From: "Scott Manthe" > To: > Sent: Sunday, February 09, 2014 1:32 PM > Subject: Re: [Elecraft] A confession > > >> Think about your "problem" this way: When Yaesu wanted to upgrade the >> FT1000MP, they brought out the more expensive and poorer-performing Mark-V >> Field (sorry if I offend, but the difference in RX performance between the >> two has been long noted).

Re: [Elecraft] (OT) -- Regarding the QRP Discussion
I would not say the Omniangle is a compromise antenna if it works :-) The operator had nothing else to compare it with and was able to make many contacts with it! We would all like a big Yagi I guess, but they weigh more than a few pounds. The thrill really, is doing more..with less! Incidentally, I am about to find out just how good an Omniangle on 20 metres is, Dale shipped mine out, earlier this week. 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 > On 7 Feb 2014, at 11:05 am, stan levandowski wrote: > > FYI - if any Listers here happened to work 3DA0US in the last couple of days, > you might be interested to learn that he was running a KX3 at between 5 and > 10 watts depending upon his DC input level.

Re: [Elecraft] Vedr: [KX2]
Ray, The most feasible way would be a retrofit surface mount prebuilt SSB module and its interface requirements for the existing KX1. People still build the radio but simply add the SSB module IF they want it. Like everything..publicise an expression of interest request, see what happens. No, Elecraft don't have to make it but, it would be nice if they did :-) Look at the HCT, started as a project and evolved into a product, specifically for one radio model, the KX3. I wonder how many KX1s have been sold, to date? 73, Jack VK4JRC Club.www.cqara.org.au Member WIA SARL ARRL GQRP #14392 QRPARCI #15068 VKQRP.#833 > On 7 Feb 2014, at 7:28 am, Ray Sills wrote: > > Well, as much as some would like Elecraft to make a "KX2" it looks like > it's not going to happen.

Re: [Elecraft] Vedr: [KX2]
I agree with Martin, the SSB module added to the existing KX1. The KX1 being a builders kit radio now, the space inside may be at a premium, so the SSB module could be a pre made one as surface mount components, so it could fit inside, without making a new case etc?

[Elecraft] Weird Thing with K2
I just got a s/hand K2 and was going through the menus and after reading the manual and checking it's settings, I discover D19 is set ON, but the radio is not fitted with the K60XV option. so, I turn it OFF This caused my 40 metre output power level to drop to 4 watts out, even with the power knob set full on. Same thing with the ATU IN or OUT. Problem solved when I set D19 back ON.

Re: [Elecraft] Flying with K2
David, I approached Qantas Airways to carry a battery on a trip to Lord Howe Island, off Australia's east coast. I made formal enquiry and received an approval document (see below) to carry the battery, with certain requirements, on the airline's part. Note the reference to IATA A67 DGR, which is an International regulation, also note ICAO, which relates to secure packaging, some battery makers have this certification and the battery will be so marked and also referred to, in it's MSDS document. Sonnenschien is one such battery. The battery I carry is a 9 amp hour, weighing 2.6KG. After this, is individual airline operator approval, which is administered as part of their internal safety policy. I can carry this battery, anywhere in the World, on a Qantas flight, the approval is good for the whole calendar year that it was granted. I just show the approval document at checkin and it's noted against my passenger details and that is it :-) My approval request was sent directly to the Dangerous Goods section of the airline and was no problem. Do not go to any other part of the airline organisation, they have no knowledge and they just solve the problem, by saying NO! The battery MUST be marked on it's outer casing with IATA A67, and have the supporting MSDS document from it's maker. Maybe you could make a trial enquiry with your chosen airline and see how you go? 73, Jack.

Re: [Elecraft] No RTFM
After being on the reflector for a few weeks and reading all the posts on the K3, I thought that maybe the K3 would be too much radio, for me! So, I have a K2 kit here, I have started to build, amongst buying a secondhand K2 and KX1. As far as me getting a K3? My best prior investment may be to buy the KE7X book and read it thoroughly. IF I can understand it's contents, there maybe a chance I could drive the K3? I always read manuals, but sometimes miss the vital messages contain therein. It is very hard to produce a manual that everyone can totally understand, I guess that is the good part about this reflector, great help is never very far away :-) 73, Jack VK4JRC Sent from my iPad __ 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] XG3 Sending Morse?
Now I have a new XG3 in my hot little hands, thought it was time for a fiddle. After studying the release notes etc, I cannot see any place in the software to set the PF1 memory? Is this what I need after sending WM,[13de_vk4jrc:03[20de_vk4jrc:03[30de_vk4jrc:03[40:03#; to the XG3? Despite doing this in the command line, the XGS does not send anything, other than its continuous carrier. I have successfully upgraded the firmware to 1.14, that process worked fine. Does PF,01,01; need to be included in the above command string, to write to the memory, so the PF1 button will set the XG3 to transmit the string?

Re: [Elecraft] KX3 vs. K3 and other rigs?
The KX3 will be just what I need, for my kayak, marine mobile ;-) http://vk4djc.webs.com/apps/photos/album?albumid=11608735 73, Jack VK4JRC On Mon, Jun 6, 2011 at 9:21 PM, Buddy Brannan wrote: > More to the point, and maybe I'm missing something very obvious, wouldn't > having as good a receiver as possible be nothing but good for portable, > compromise antenna operation?

Re: [Elecraft] KX3 pics + Newbie.
This is my first post to the group, I am an Elecraft "newbie" having just bought a K2 kit for SSB and having owned a T1 ATU for some time. I am also a digital modes freak! Operating portable/mobile is my main interest. I have a collection of portable radios, including my Codan X2 backpack pedestrian mobile setup, what with 3 Icom 703, 1 FT817, 2 Icom 7200, 1 SG-2020, 2 Icom 706MKII radios, I am really looking forward to the KX3 radio:-) The KX3 will be a great radio, just as it is:-) It's easy to 'add' ideas to any product design, after you see what the KX3 is going to be. Just imagine what would result IF everyone was asked to design a radio along the lines of the KX3 from the ground up. For a start, it would be unaffordable, the RX current would be high (because of all the junk bells and whistles in it) I could go on, but I won't :-) Just produce the KX3 as it is, so I can I buy it soon! 73, Jack.
