Re: [Elecraft] [KX3] KX3 and Digital Modea (KM4VX)
I have found that the use of an inexpensive computer type fan on even low power running behind the KX3 works well in allowing the full use of the digital modes, to include WSPR at 5 watts full cycle of 112 seconds. Thank you for all the thoughtful inputs. Running WSPR at 3 watts does not require the fan, but at 5 watts the fan is adequate. The radio gets warms, but does not overheat.

Re: [Elecraft] [KX3] KX3 and Digital Modea (KM4VX)
FWIW and don't know how this would work on a KX3 but ... When I still had my KPA100 on my K2, and was using the K2/100 in RTTY contests, I stuck a brushless 12 VDC computer muffin fan to the top of the heat sink, blowing down, with a little tab of velcro over the PA's. I have a digital thermometer with a remote sensor on a very small wire, and I tacked it to one of the PA transistors. I was able to run in a contest at 100 W and the PA temp stayed well within limits. The heat sink stayed cool to the touch. As I said, FWIW. I finally sold the KPA100 and use my K2 as my field rig with the Alex Loop and no digital now. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/23/2015 1:40 PM, KM4VX wrote: I have found that the use of an inexpensive computer type fan on even low power running behind the KX3 works well in allowing the full use of the digital modes, to include WSPR at 5 watts full cycle of 112 seconds.

Re: [Elecraft] OT: Ground Loss (long)
True, at least from my experience. If you're on a pointy part of the Earth [aka summit such as in SOTA], the far field effects can and often do lower the max elevation angle to or below the apparent horizon. Most antennas on summits exhibit a host of other inefficiencies as well, but the effect is there. I used a vertical GP with my Buddipole on summits only because the horizontal OCF loaded dipole configuration was worse. One thing that hasn't been mentioned is noise on RX. It seems like the preponderance of man-made noise is vertically [more or less] polarized. Until last Sunday, I had a Gap Titan on the roof. Good antenna, very low SWR on all its bands. Nearly all the time, noise was 1-3 S-units higher than on my tribander or dipoles. I did keep checking because occasionally, mainly on 12 and 10, it was lower than the TB. Man-made noise may not be a problem in a remote, back-packing environment of course. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/23/2015 4:30 PM, Don Wilhelm wrote: For the lower frequency bands, the height of a dipole with those characteristics is not practical for most hams and the vertical wins hands down for DX - provided a good radial field or elevated radials are used. 73, Don W3FPR __ 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] Atmospheric noise increases
Has anyone else noticed the dramatic increase in atmospheric noise lately? On 20M, 30M, and 40M especially, I see a wide-band noise source wandering back and forth across the bands. At times it almost looks like a sine wave on the waterfall display. The noise will vary from an S3 up to a 20/S9. It is especially troublesome on the frequencies I use most, namely, 10.1389, 14.045, 14.070, 7045, and 7070. With the antenna disconnected, the noise drops to S1 or less. I use 3 different antennas, a Force-12 15 ft vertical about 50 feet from the house, a homebrew 25 ft flagpole vertical about 30 feet away and an inverted vee for 40M on the tower adjacent to the house fed with 450-ohm ladderline to a 4:1 balun at 50 feet. All three exhibit the same patterns and are separated by at least 50 feet from each other. I am using the Rocky utility connected to the I/Q output of my KX3 to a 48KHz USB sound card input to the laptop computer. -- W7HD KX3#6966 Licensed continuously since 1967 Now retired!

Re: [Elecraft] OT: Ground Loss (long)
Near field soil conditions become less of a factor with the use of elevated radials. Consider a ground plane antenna with the base mounted at the rooftop of a 1 or 2 story building - it is reasonably independent of near field ground conditions because it is an antenna within itself - much the same as a vertical dipole. A vertical with buried radials is quite dependent on ground conductivity unless the number of radials is large. The far field ground conditions still do play a part and what Jim has pointed out below is valid. IMHO, the main advantage of a vertical is that it has a null at the top of the elevation plots which will reduce the response to high angle reception (nearby stations). If you look at the elevation plot for a horizontal dipole along with a vertical, you will see that the dipole has almost as much gain at low angles as the vertical - so from a pure gain standpoint, the vertical offers no advantage. BUT that is comparing a vertical with a high dipole (at least 1/2 wavelength high). For the lower frequency bands, the height of a dipole with those characteristics is not practical for most hams and the vertical wins hands down for DX - provided a good radial field or elevated radials are used. 73, Don W3FPR On 7/23/2015 11:10 AM, Jim Brown wrote: On Wed,7/22/2015 6:15 PM, Al Lorona wrote: This suggests that ground loss is sort of an impedance-matching problem. Clearly, as your ground gets really bad your antenna can still work just fine, even better in some cases! Hi Al, Several observations. First, soil influences vertically polarized antennas in two ways. First, loss in the soil near the antenna as the field from the antenna causes current flow in the ground. The result is simple I squared R loss, and that power does not get radiated. Second is the reflection from the earth in the far field where the radiated field hits it. That reflection adds (algebraically) to the direct signal to form the vertical pattern. The strength of the combined direct signal plus reflected signal depends on the relative phase angle between them, which in turn is a factor of distance, the elevation angle, and the soil. The second point is that conductivity is not the only soil parameter. There is also the dielectric constant. In EZNEC, if you open the Ground Description tab and right click on either Cond or Diel Const, you'll get a window showing a continuum of soil types from very good to very poor. BOTH Cond and Diel Const vary with those soil types, and both quantities affect how the antenna behaves. A year or two ago, I did an extensive study of the interaction of vertically polarized antennas with soil of different types and at different mounting heights. I presented it to the Pacificon Antenna Forum using these slides. http://k9yc.com/VerticalHeight.pdf 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 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] K-Line mounting
If you look at my (N1HEL) QRZ.com page, you will photos of my K-Line gear arrayed in its bookcase structure, which is securely mounted to the (extended) dinette table of my RV, which in turn is permanently braced and bolted to the floor. (The RV serves ONLY as a mobile comms van.) The pieces sit atop non-slip rubber matting. When I travel, I secure the tabletop level gear (the K3/P3 on the left and my Astron on the right) by means of bungee cords that run (a) from the front edge of the table to its back edge, hooking into screw eyes on the front and back edges of the table (You can see the screw eyes in the last picture of the bunch.) Shorter cords are used to secure the K500 and the tuner, which are on the second level (left side) and my VHF/UHF gear, which is mounted to a plywood board and sits on the top-left level. For the high-levels gear, screw eyes and S hooks on the edges of the shelves are user to anchor the bungee cords. So far, the gear has seemed very stable under bungee control, although I must admit that I have only run on paved roads. It takes me 5-10 minutes to secure everything. -Paul, N1HEL __ 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] [K3] Firmware Update Saga
Hello All I recently ordered a KRX3A and KSYN3A board for my K3. I was running firmware version 4.58 so I thought I'd better update it in readiness for the new arrivals. The computer I use for radio is 32 bit running Win98se, it works very well with my homebrew logging program which integrates with the K3. I did try porting it to WinXP but met with problems, if it ain't broke don't fix it, so stuck with 98se. This computer dual boots to Linux Mint12, which runs K3utils. My internet computer is 64 bit and dual boots Win7 and Linux Mint17. I use Mint17 for all internet work so I downloaded the Latest Linux K3utils (1_14_10_24) and installed it, I tried to run it nothing happened. After a session of 'Googling' I found that K3utils is 32 bit and needed 32 bit files loading to make it run on a 64 bit machine, I decided against this and downloaded all the .hex files, transfering these to Linux Mint12, connected the K3, and tried running the Util. It could not find the port displaying the message 'access denied'. After trying various things, without success, I went 'Googling' again, this time I found the problem was, as the User, I wasn't a member of the group 'Dialout', which gives access to serial ports on Linux, on joining this group the Util now worked OK. It was Sunday afternoon with time to spare before my evening meal, I decided to bite the bullet and run the upgrade to 5.29. I had not updated the firmware for a while and could not remember how long it took. Off it went, my meal was ready and still it churned on and seemed to be running slower and slower, I left it, had my meal and came back to find it was still plodding on. It took 4400 seconds according to the display on the Util. With fingers crossed I turned the K3 off and on again, yippee it worked, very much to my relief, in view of some of the problems posted on the reflector. The newly ordered parts arrived and were duly installed. I had to run the K3util to install the firmware for DSP2, this took 2200+ seconds, is this normal for firmware loading? All is working FB, and getting to grips with listening to different stations in each ear!! If anybody else has the same or similar problems, I hope in some way this helps, If nothing else it might have caused a chuckle or two.

I used to have fans as one of my categories back when I was employed as a components engineer at Hewlett Packard. One thing I remember is that even a small amount of moving air makes a big difference in a heat sink's thermal resistance. You don't need a huge fan. Alan N1AL On 07/23/2015 01:40 PM, KM4VX wrote: I have found that the use of an inexpensive computer type fan on even low power running behind the KX3 works well in allowing the full use of the digital modes, to include WSPR at 5 watts full cycle of 112 seconds. Thank you for all the thoughtful inputs. Running WSPR at 3 watts does not require the fan, but at 5 watts the fan is adequate. The radio gets warms, but does not overheat. My KX3 came with the latest heat sink from ElecraftI, have not performed the temperature compensation mod, and will not be buying any after-market heat sink. 73 Ron KM4VX -- View this message in context: http://elecraft.365791.n2.nabble.com/Re-KX3-KX3-and-Digital-Modea-KM4VX-tp7605181p7605261.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 Message delivered to n...@sonic.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] Atmospheric noise increases
If it is wide band, but not all over the entire band,, it's probably not atmospheric noise, more likely created by humans [i.e. your neighbors]. Especially if it drifts up and down slowly. Odds generally are that it's correlated with the slowly increasing use of LED and CFL lights ... and possibly increases in indoor agriculture. The latter can generally be identified by a fairly strict schedule of on and off. I have one near me. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/23/2015 5:07 PM, w...@msn.com wrote: Has anyone else noticed the dramatic increase in atmospheric noise lately? On 20M, 30M, and 40M especially, I see a wide-band noise source wandering back and forth across the bands. At times it almost looks like a sine wave on the waterfall display. The noise will vary from an S3 up to a 20/S9. It is especially troublesome on the frequencies I use most, namely, 10.1389, 14.045, 14.070, 7045, and 7070. With the antenna disconnected, the noise drops to S1 or less. __ 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] OT: Ground Loss (long)
On Wed,7/22/2015 6:15 PM, Al Lorona wrote: This suggests that ground loss is sort of an impedance-matching problem. Clearly, as your ground gets really bad your antenna can still work just fine, even better in some cases! Hi Al, Several observations. First, soil influences vertically polarized antennas in two ways. First, loss in the soil near the antenna as the field from the antenna causes current flow in the ground. The result is simple I squared R loss, and that power does not get radiated. Second is the reflection from the earth in the far field where the radiated field hits it. That reflection adds (algebraically) to the direct signal to form the vertical pattern. The strength of the combined direct signal plus reflected signal depends on the relative phase angle between them, which in turn is a factor of distance, the elevation angle, and the soil. The second point is that conductivity is not the only soil parameter. There is also the dielectric constant. In EZNEC, if you open the Ground Description tab and right click on either Cond or Diel Const, you'll get a window showing a continuum of soil types from very good to very poor. BOTH Cond and Diel Const vary with those soil types, and both quantities affect how the antenna behaves. A year or two ago, I did an extensive study of the interaction of vertically polarized antennas with soil of different types and at different mounting heights. I presented it to the Pacificon Antenna Forum using these slides. http://k9yc.com/VerticalHeight.pdf 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
[Elecraft] [K3] KXV3B - No missing pin
Am installing a KXV3B into my K3 #266. The latest manual (Rev C1) says it’s normal for one of the pins that plug into J66 to be missing (third from right looking from front panel). In my case there is no missing pin so I’m wondering if that, too, is normal? Anyone come across this? It would be easy to remove but I’d rather not if it’s alright to leave it. 73 to all Geoff G3UCK __ 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] [K3] KXV3B - No missing pin
Many thanks, Don. Keith at Elecraft sent me a direct reply too - good service as usual. My question answered in just over an hour! It is as you say. There is nothing on the KXV3B pin in question so there is no need for it to be removed in the case of an early K3 like mine that does not have the keying plug in J66. 73 to all Geoff G3UCK -Original Message- From: Don Wilhelm Sent: Thursday, July 23, 2015 5:39 PM Geoff, Look at the mating female connector. If there is a plug in that connector that matches the third from right pin, you will have to remove the pin. Those are keying pins to assure that you do not misplug the connectors by being one pin off. If there is no keying plug in the female connector, then you do not have to remove that pin - but be careful to insert the pins correctly. 73, Don W3FPR On 7/23/2015 11:07 AM, Geoffrey Downs wrote: Am installing a KXV3B into my K3 #266.
