Re: [Elecraft] (Elecraft) Laptops/Notebook Suggestions
I would like to second Tony, KT0NY, regarding ASUS 11.6", Core I3, Win 8 Laptop. I purchased one about one month ago at Best Buy for less than $500. I had been shopping for small laptop for some time with Win 8 but did not want to spend $1000 for one. The ASUS fits the bill very nicely and works with the K3/KX3 very well. Would highly recommend. 73, Steve W0SZ __ 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] KBPF3 General Coverage Receive Option Questions
N1LQ-Dave: I have the KBPF3 installed in my main receiver. I needed it to use my K3 down on the 600m band (495-510 KHz), so having it in the main radio is necessary for transmitting on 600m using the TEST mode. Probably not a very common usage, but I thought to mention this. I have the 13-KHz FM filter, 2.8-MHz and 400-Hz CW filter installed in the main receiver, so only use the 13-KHz filter for VHF-FM or BC AM. Use of the DSP filter makes the 13-KHz filter a good choice as roofing filter, since one can tailor bw using the DSP filter. Audio bw is <4-KHz in any case. 73, Ed - KL7UW __ 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 Reduced BW FSK
Interesting thread on the AFSK DSP width reduction. Supposing all goes well, will we see a release of new firmware which will include the new data!!!

This was shown in his write-up posted at http://www.frontiernet.net/~aflowers/k3rtty/k3rtty.html Note that this does NOT indicate that there was any sort of problem with the K3, just that there was a chance to be better. Other manufacturers also have this same chance to improve. A little later, Ed, W0YK, also known as P49X in many contests, announced that he had successfully used experimental DSP firmware from Elecraft in the BARTG rtty contest. “The K3 DSP firmware engineer coded a wave-shaping filter that narrows the transmit bandwidth similar to what their AFSK filter provides. The resulting spectrum image looks like the better, i.e., narrowest, of the images in K0SM's recent work.” Elecraft then allowed Ed to share this firmware with others who were interested in trying it, which is how I got it. As anyone who was in the WPX RTTY contest this past weekend knows, anything that can help reduce the unnecessary interference from overly wide transmissions is more than welcome. It is great that Elecraft has reacted so quickly to this opportunity. (Would we expect anything less from these guys??)

Re: [Elecraft] K144XV Problem
Might double check your xvtr settings in the menus and make sure they look right. If you have a recent good config backup of the K3 you can try restoring it. Other things to try: - Direct setting the frequency via the keypad. - If you have quick memories assigned to M1-4 keys to set 2M favorite frequencies try that. - Check to see if you can hear a known frequency like packet on 144.390MHz or a FM repeater. Perhaps the .XXX portion of the dial is accurate as is the xvrter and the XXX. portion of the display frequency is corrupt. - Spin the dial either side of 146.0 causes the xverter to switch local LOs. Any of these methods might get you back were you belong. - Mike -- View this message in context: http://elecraft.365791.n2.nabble.com/K144XV-Problem-tp7569906p7569935.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] [K2] KAT2 Question
Hey all, I've been working on the KAT2 module for my K2. Mostly making progress but stumped in the bridge null adjustment. I was having problems with C55, and getting silly readings on U4 Pin1, so after staring at my board for a while, I went to the web for a while and read about other folks' problems and figured out I had wired J7 backwards on the control board. I fixed that, which brings us to my problem... I set ATU CALn in the menu, exit, hit 'TUNE' like I did before, and instead of getting the mV reading like I was before, I just get a power reading - e.g. "P 4.5". I can't seem to get back to what I was looking at before. I went back and checked the other tests again ... I have everything in ATU mode in the menu, I can make the relays go clicky-click when I run through that set of options in the ATU menu, but I can't get this null mode to work. I was able to get it to work when I had the RF cable J7 wired up wrong. Ideas?

Re: [Elecraft] [K2] KAT2 Question
Brian, Are you certain you had the J7 connector backwards? The coax shield should be toward the right side panel. The results you are now getting indicate that you have something wrong with what you changed. That power reading is likely coming from the K2 RF board RF output detector rather than from the KAT2. If that is the case, the KAT2 is not being recognized - check the connector to the Control Board. An inability to achieve a null on C55 is usually an indication of a problem with T1. Check that it is wound in the same direction as shown in the manual. Check that the proper color leads are in the right holes. Look at the solder side of T1 - there should be no rings in the solder around the leads - that is an indication that the leads were not well stripped and tinned. I would suggest removing T1 and re-winding it. It MUST look just like the diagram in the manual or it will not function properly. 73, Don W3FPR On 2/14/2013 9:18 AM, Brian Handy wrote: Hey all, I've been working on the KAT2 module for my K2.

Re: [Elecraft] OT: G5RV's and variants
Ron, I've modeled my antennas using EZNEC. What I've found is that the horizontal pattern is more sensitive to conductor length on dipoles. Electrical height determines vertical angle of arrival. For NVIS work on 40 30' high is good; double that for 80. However,as you get higher than 1/4 wave the lobes start to lay down. there is an exception to this and that is a null that is created at the horizon that can occur when you get to certain heights between 1-2 wavelengths above ground. It's part of an interference pattern. The Carolina Windoms are really interesting affairs. they are designed to have radiation from a part of the feed near the dipole. I've chosen to use an18' radiation length on my 66 footer. This allows a little better radiation at the horizon on the lower frequencies with a small impact on ten. However, at 22' things got crazy, so, 18' became the magic number. Using these configurations for a fair number of years I find that this seems to work. I do reach out and touch people when band conditions are in good shape, and in the present iteration, the antenna is at about 40' on one end and about 30 feet on the other. This is not by design but rather by aim and the slope of the ground. I do run both QRP, ~5 Watts and QRO, 100 Watts. What I do and what I say about antennas are NOT absolute. These are good guides that can be tailored for specific locations. The only important thing to remember, IMHO, is antenna tuners take care of many bad estimates and low loss feed lines mask many mistakes. 73, Barry K3NDM On 2/14/2013 1:29 AM, Ron D'Eau Claire wrote: If you like to use it for chasing DX on 10 meters, you'll get better results with a slightly shorter radiator - something about 42 feet overall. That's because a longer antenna generates a big lobe pointing straight up on 10 meters - not very helpful for DX-ing on that band. At 42 feet the main lobes are still down near the horizon on 10 meters. At 42 feet, the efficiency is excellent down as low as 40 meters. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of k3...@comcast.net Sent: Wednesday, February 13, 2013 5:37 PM To: Ken G Kopp Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] OT: G5RV's and variants >From my experience, hams misunderstand antennas more than anything else they have as a part of their station. What I've been able to discover for the popularity of the G5RV is that you have an "all band antenna" in just 102'. The other issues have to do with the concept of resonance in an antenna system and the need for it. I guess I'm just not smart enough to worry about all of the issues. My approach has been to just hang up 132' or 66' of wire fed in the center with open wire to a 4:1 balun near the house. My transition into the house is either something like LMR-240 or LMR-400 to my tuner. I can use this configuration either 80-10 or 40-10. Resonance? I really don't worry about it too much as my tuner can address the issue for me thereby making my transmitter happy. I don't worry about losses either. With low loss feeds, there is little loss, even at 10 meters, with SWRs as high as 10:1. Simplicity is key here. The antenna that I now have up is roughly equivalent to a 40 meter Carolina Windom, modified. My thinking on this gets a little convoluted, but it works. For a new installation with the room, I would suggest the center fed dipole with low loss feeds into a good tuner.

If the tuner as no internal balun, one can be made or purchased. I once knew a local who actually coiled the coax portion of his G5RV's feed "system" behind his desk and then connected it to his tuner. The end of the balanced portion was within inches of his tuner's balanced line connections. The G5RV certainly qualifies as a "cult" antenna. 73! Ken Kopp - K0PP ___
[Elecraft] K3 with 2m module K144XV
Lance, As you know I am active on 2m-eme. I can't give any opinion on the K144XV but have a couple comments on frequency stability requirements for JT65B. Many stations use the "Freeze" function to reduce the decode spectrum to 20-Hz. Mainly this is in a crowded band with many stations calling. Therefore, I would say one needs overall frequency to stay within 20-Hz. My DEMI 144-28 transverter drifts upward 5-Hz after running JT65 30-minutes at 50w. My K3 adds about 2-Hz to that keeping the total drift easily within a 20-Hz target. I have the K3EXREF installed with a surplus OCXO from e-bay (approx. $45) as 10-MHz standard. That keeps the K3 at 28-MHz within +/- 2-Hz (or 0.1ppm). Without the K3EXEF the K3 runs about 14-18 Hz off freq. which is close to the TCXO3-1 spec of 0.5ppm. The transverter runs a PTC heated xtal oscillator on 116-MHz. Actual drift on 28-MHz has not been measured on the K3 so it may be less. You may be happy running the k3 without the K3EXREF. It would all depend on the additional drift of the K144XV (so maybe some who have this will comment). 73, ED - KL7UW PS: I have another DEMI 144-28 transverter with a VHF PLL and it is < +/- 1Hz. I installed the PLL to have two LO freq.

Re: [Elecraft] OT: G5RV's and variants
Interesting observation, Ken. After seeing a upsurge of interest in G5RV antennas discussed on various ham radio reflectors (and noting that the interest seems most enthusiastic among newly-minted hams), I honestly feel that the recommendations from one new ham to the next seems to be based on trumped-up theory that the G5RV is an all-band antenna. Almost every new ham would like an inexpensive, easy-to-build, low profile antenna for "all bands". While we know that the G5RV *can* be made to work OK on several bands with a tuner, I feel that this new found G5RV interest is a self perpetuating rumor spreading like a bad cold among newcomers.

Re: [Elecraft] OT: G5RV's and variants
There is a reason that the G5RV is a good beginner's first antenna, IMO. It is relatively easy to install. Of course the same size antenna performs better as a doublet fed with balanced line, but I had a lot of trouble with balanced line when I was starting out. I didn't know enough to get usable matches. Feedline length, routing and balun issues, while simple for me to solve now, were just too much for me to solve in the beginning. The G5RV got me on 10, 12, 15, 17, 20, 40, 60 and 80 all at once. Admittedly not very well on all, but I made contacts on all those bands.

Re: [Elecraft] OT: G5RV's and variants
I have always been amused by the antenna adverts that say things like "I worked 100 countries in 6 hours" or some such nonsense. Those type ads never give radiation patterns or any other meaningful data that can be used to compare with other antennas. That does not mean that the ads were mis-leading, but the fact that however many contacts were made is really meaningless. The fact is that any antenna will radiate and can make contacts unless it is rolled up and sitting on a shelf in the basement. 73, Don W3FPR On 2/14/2013 4:03 PM, hawley, charles j jr wrote: Yes sure...

Re: [Elecraft] K3 with 2m module K144XV
Lance Having tried the K3 with the high spec oscillator and with the external locking I found I needed the external locking for my 144 digimode qsos. However my eme shack varies between around 37F and 110F (outdoor garage) so it is expecting a lot of the internal reference External locking of the K3 also helped when using the internal transverter to drive external transverters at 144MHz for 1296, 2304 and 3400 digital EME qsos If you lock the k3 reference and the 144 xverter inside the K3 it is vital to do the mod at http://www.elecraft.com/K3/mods/K3EXREF%20freq%20shift%20fix.pdf Not sure if the "Production phase-in is pending."

I have a K3 with the optional high stability reference oscillator option. I have been very pleased with the frequency stability of the unit up through 6m. Next month I am interested in ordering the K144XV so I can also use the rig for 2m EME with JT65B mode. Is there anyone out there currently using such a setup successfully on 2m EME? Is it stable enough as-is, or will I need to also add the K3EXREF and some additional outboard frequency standard? I would like to avoid involvement with the K3EXREF unless it is required. I do not plan to use the K3 2m as an IF for microwave transverters, so I hope it will be stable enough on 2m without it. I look forward to your experience!

Re: [Elecraft] OT: G5RV's and variants
A 66ft off-centre-fed dipole works better than the 105ft G5RV worked on multiple bands. Remember, however, that when Louis Varney designed his antenna (aerial in those days, probably) we all had valve (tube) transmitters which could cope with the wide variation in impedance. My only matching unit was for top band. I didn't use a matching unit for the other bands until I had a transistor rig. David G3UNA There is a reason that the G5RV is a good beginner's first antenna, IMO. It is relatively easy to install.

[Elecraft] K3XREF Question
Hi Don and All IMHO using a GPS disciplined 10 MHz (Trimble etc.) or a Rubidium standards are unnecessary , expensive and overly complicated approaches, to be used as the K3XREF 10 MHz external source. There are extremely stable (as high as 10 x-12th) Double Oven Controlled Xtal Oscillators (OCXOs) available on the Off Shore surplus market, for under $50 delivered. These are pulls from US built surplus equipment, and are guaranteed and tested . I have bought several, and the latest one has been bench tested for several months, and after initial adjustment has not varied a single cycle on my GPS locked counter. Even this stability, is an overkill, when used as an external reference for the "frequency", not "phase" locked K3. These OCXOs are less than 2" cube in size and available on e-Bay from several dealers. Check e-Bay under the subject OCXO.

Re: [Elecraft] K3XREF Question
Yes. I have had the GPS system and also the Rubidium and other than seeing my HP counter with the oven controlled oscillator agree with them from time to time, I have to say it was pretty boring.

Re: [Elecraft] OT: G5RV's and variants
My 2 cents, As a relatively new ham lacking any real world skills with regards to making antenna's, the G5RV has worked for me. I am very limited in time, I am not normally home more than 10 days a month so my spare time is limited. But I still have some time to enjoy the hobby and personally I would rather spend what time I have getting on the air. That being said the G5RV has done what it promised, I have made contacts on 80 through 10 meters and I always am able to tune any band with less than 1.5 SWR using the K2's internal tuner. I am only running 10 watts and have made contacts as far away as the Ukraine from my east coast QTH so it seems to getting out. I'm sure there are better antenna's and some day I would like to have something more than the G5RV but for now it works for me. Anyhow I don't really understand why the G5RV is so controversial.
