Re: [Elecraft] [KX3] CMP/ALC display won't change
Do you have the KX3 in « CW in SSB » mode? If you go to the CW WGHT menu, and tap the « 1 » button, it will turn this feature on (SSB +CW) or off (SSB -CW). Also check that you don’t have it in SPLIT mode (with other VFO in CW mode) — you’ll see « SPLIT » on the screen if that is the case. -- 73 de Matt VK2RQ Le 26 juillet 2015 à 1:27:45 PM, Gary Hawkins (g...@hawkins-zhu.com) a écrit: I'm in USB mode and CMP/ALC is displayed.

Re: [Elecraft] OT: Ground Loss (long)
Hi All, I cannot improve, or add much to, the excellent commentary provided by Jim Brown and others. However, I can say that my experience tends to confirm a lot these findings. First, I originally had an R7 vertical ground mounted. Performance was O.K., but certainly not very exciting. Later I elevated that antenna to about 15 ft. above ground, and the improvement was very noticeable. Subsequently I have replaced the R7 with an F8 (acquired in an estate sale), and the results are very much the same--the antennas are not all that much different anyway, but the R8 is a bit taller, and does cover 6 meters (after a fashion!). If you look at the study Ward Silver, N0AX, did many years ago on various vertical antenna systems, the R8 is rated one of the very best. In any event, I've worked well over 100 countries QRP on 40 meters using this arrangement. After hearing Rudy Severns' presentation about ground systems at Pacificon several years ago, I began elevating radials when using my portable antenna systems while camping. Most of this was done using either an MP-1 or a Biddipole configured as a Buddistick. Again, the results were very rewarding. As Rudy indicates, elevating your radials even just a small amount can result in significant benefit. Usually I try to deploy 4 elevated radials. Sometimes, though, only 1 or 2 are practical under the circumstances. Still, it helps! I also acquired a used Sigma 40XK, and now use it as my primary 40 meter antenna at home. That antenna is raised about 6 feet off the ground, so the overall height is about 20 feet or so. I wish I could go higher, but neighborhood restrictions prevent that. I get a 1 to 3 Db improvement with this antenna over the R8, measured by comparisons using the RBN system. I've become a big fan of vertical dipoles! When I go QRO (500 watts for me), I get some reports from DX stations that I consider to be exceptional. I also monitor myself on the RBN, so I have some idea as to who might hear me and who can't. It's almost better than trying to interpret some of the propagation software. I also have one of N6BT's Bravo 7 antennas, which he calls vertical dipoles also. By the way, N6BT also designed the Sigma 40KX when he owned Force 12. Anyway, the Bravo 7 works pretty well as a portable system, but I'm not quite as happy with it as a 40 meter system. Still, it is very portable, and easy to put up and take down. N6BT makes some pretty aggressive claims about the performance of this system, but I am pretty sure most of his testing was done over salt water. In any event, the higher up I deploy that system, the better it seems to work. I think Jim Brown's suggestion of adding a better radial system to vertical dipoles may be exactly what I need to try and do with the Bravo 7, particularly for 40 meter operation. Soil conditions here in Arizona are pretty awful. It's not very often that I go camping anywhere that offers anything much better. Deploying elevated radials can be problematic, but it certainly seems worth the effort most of the time.

Re: [Elecraft] Cwskimmer Bandwidth and more
Only when there is a direct connection to one of the hard coded SDRs, such as: SDR-IQ, QS1R, Mercury or Perseus. When you use a K3 with an SDR-IQ, for example, you will see a pan adaptor display of up to 192 kHz, but CW Skimmer (setup as SoftRock-IF) will still be limited to much less than 48 kHz. Now if you have found a way around that, myself and many more would like to know. 73 de Sebastian, W4AS On Jul 24, 2015, at 6:41 PM, Doug Ellmore d...@ellmore.net wrote: Don, cwskimmer settings allows up to 196khz.

Re: [Elecraft] K3 Setup for TX at 630 Meter Band
John, Wayne covered the technical aspects of transmitting on 630m, but there are legal aspects that all newbies with K3s and upgraded K3's should be aware. There is NO HAM BAND on 630m so your ham license is invalid for transmitting on those frequencies (FCC promises someday - don't hold your breath). The only way to legally transmit is to obtain an experimental license from the FCC for use of 630m. I am not prepared to walk you thru that - just saying its a lot more involved than a ham license. If really interested in getting on before amateur radio is approved, I suggest you get in touch with the ARRL Experimental Group: http://www.500kc.com/ ARRL has just submitted renewal of our license: WD2XSH.

Re: [Elecraft] 200 Hz 5-pole filter
One can download the Sherwood list and save it to an EXCEL file. Then sort it by your own choosing. The Sherwood list is presented on one parameter only being dynamic range, narrow spaced.

The point is that there isn't going to be much difference between the 250hz 8 pole filter and the 200hz 5 pole filter. But think about your comment for a moment. A stock K3 with no additional filters is that good enough to rank that high. It might actually rank higher, because the ARRL and Sherwood methodologies differ. In any case, far too many people are far too concerned about the Sherwood rankings. Most people don't understand what the data mean and only worry about where a radio ranks on the list. The few dB between radios at the top of the Sherwood rankings means the list could probably be reordered based on component differences in production runs.

Re: [Elecraft] 200 Hz 5-pole filter
Not in most cases, since turning on the attenuator significantly reduces the MDS (sensitivity) of the RX. IMDDR3 is the difference between the input RX sig levels that created the IMD and the MDS of the RX. It may increase IMDDR3 slightly, or even reduce it, depending on which RX stages go into distortion at high levels first. But who wants a deaf RX that can not hear down to the noise floor of the band? What turning on the attenuator (or having a poor sensitivity RX) -does- do is artificially increase the iP3 number, rendering it meaningless as a number for comparing different receivers which have -different- RX sensitivities for that measurement. Some manufacturers have gamed this number for years. For best comparisons, receivers should be compared at the same sensitivity level.

Anyway, the Bravo 7 works pretty well as a portable system, but I'm not quite as happy with it as a 40 meter system. Still, it is very portable, and easy to put up and take down. N6BT's verticals ARE vertical dipoles, loaded in some quite innovative ways. W6GJB and I are building an 80M vertical dipole for FD and CQP based on some of Tom's ideas. N6BT makes some pretty aggressive claims about the performance of this system, but I am pretty sure most of his testing was done over salt water. I've not known Tom to puff his antennas with exaggerated claims. He's a very good designer, and my experience with him is nothing but honesty. It is, however, well known that verticals work awfully well over salt water, and he's written extensively about that. In any event, the higher up I deploy that system, the better it seems to work. I think Jim Brown's suggestion of adding a better radial system to vertical dipoles may be exactly what I need to try and do with the Bravo 7, particularly for 40 meter operation. After having done some more modeling, I'm backpedaling on that suggestion. You'd need a LOT of radials over pretty awful ground to see a dB or so. Note also that the horizontal elements at the bottom of Tom's vertical dipoles are NOT radials, they are capacitive loading for the bottom half of the dipole. Don't try to add to them -- you'll detune the antenna. :) 73, Jim K9YC __ 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] 200 Hz 5-pole filter
We're hoping to add the 200-Hz filter back to our product line as soon as possible. Meanwhile, the 400-Hz and 250-Hz filters also do an excellent job. As I've mentioned before, any radio with 2-kHz IMDDR3 numbers in the 100-dB-plus range is going to be a solid performer on the air. A dB here or there above this level is really splitting hairs; it speaks more to an engineering achievement that a required level for most operators. That said, we're happy to have two of our radios in Sherwood's top four, especially when you consider the difference in price. And if you take blocking dynamic range into consideration, as well as the various footnotes, the K3S is second to none. 73, Wayne N6KR __ 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] 200 Hz 5-pole filter
No, and it's also from 2009, but that's not the point. The point is that there isn't going to be much difference between the 250hz 8 pole filter and the 200hz 5 pole filter. But think about your comment for a moment. A stock K3 with no additional filters is that good enough to rank that high. It might actually rank higher, because the ARRL and Sherwood methodologies differ. In any case, far too many people are far too concerned about the Sherwood rankings. Most people don't understand what the data mean and only worry about where a radio ranks on the list. The few dB between radios at the top of the Sherwood rankings means the list could probably be reordered based on component differences in production runs. Certainly a radio near the top ten is good enough. 73, Scott N9AA On 7/25/15 3:29 PM, XE3/K5ENS via Elecraft wrote: That is not the Sherwood receiver list that everyone covets.

I just ordered one to try out. 10 bucks plus shipping: http://www.amazon.com/Network-Output-Manual-Sharing-Switch/dp/B00AUB3SSA/ If you wanted it to switch automatically you could probably modify one of these boxes with your own relays and decoder circuit, or just build one from scratch. There are 8 pins on the connectors. Power and ground (pins 1 and 3) don't need to be switched: just wire all in parallel. VSCL (pin 4) is not used in the P3 and can be left disconnected. So for each sensor you'd need one 5PST relay to switch SCALE, SENSE, VREF, VFWD and VREV (pins 5, 7, 8, 6 and 2 respectively.

There is NO HAM BAND on 630m so your ham license is invalid for transmitting on those frequencies (FCC promises someday - don't hold your breath). The only way to legally transmit is to obtain an experimental license from the FCC for use of 630m. I am not prepared to walk you thru that - just saying its a lot more involved than a ham license.

[Elecraft] DB9 connectors
Hi everybody, Reading the Reflector convinced me that a RS232 connection is better than a USB connection between the K3 and the computer. I recently changed my laptop and succeeded in finding a laptop with a RS232 com port (HP ProBook 650 G1). The problem I'm now facing is that normal DB9 female connectors cannot be reliably inserted in the male DB9 connector of the laptop due to the physical characteristics of the male DB9 connector : there are no nuts on the laptop to attach the connector and the height of normal DB9 female connectors is too big. I looked at many supplier web pages but didn't find a thinner DB9 connector without bolts. Has anybody made the same experience and resolved the problem ?
