Re: [Elecraft] Re: Elecraft Antennas in trees
As you have I have tried many different ways of getting a line into a tree during the past 50 years, well 60 :-) The problems that I have always found with shooting, casting or throwing a thin line with a weight or ball at its end is that too often the end wraps itself around a branch or gets stuck in a piece of broken bark, and secondly to place a line exactly where I want it in a 100ft tree is almost impossible due to human error, or breeze causing the line to drift. Shooting tennis balls is a good idea, but when I tried this method too often a ball would bounce off a branch or become stuck. It would seem that I need more practice in shooting tennis ball! A local problem is that there are several Buzzards living in the trees who have an unhealthy interest in flying objects! 73, Geoff GM4ESD - Original Message - From: Benny Aumala [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Saturday, July 26, 2008 9:14 PM Subject: [Elecraft] Re: Elecraft Antennas in trees Best and easiest way to shoot antenna is here: http://www.antennalaunchers.com/csv19/index.htm I tried almost all imaginable systems during 50 years.

RE: [Elecraft] Elecraft Antennas in trees
I am not a professional tree climber and do not even play one on tv, BUT I recommend using a light rope with a plastic bottle partly filled with water as the throwing weight. That way, if the bottle breaks, u do not have 12 oz of ball bearings raining down on ur or ur neighbor's heads. Also, for the times u miss and the water bottle gets hung up in a tree, when it finally comes loose, all u get is a little wet and a light plastic bottle coming down! Also, same level of safety when the water bottle comes loose from the rope in mid flight. A slingshot or bow/arrow look great, but take care of down range hits. 73 Charles Harpole [EMAIL PROTECTED] Date: Sun, 27 Jul 2008 12:14:11 +0100 From: [EMAIL PROTECTED] To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Elecraft Antennas in trees Benny Aumala wrote: http://www.antennalaunchers.com/csv19/index.htm That URL seems to lead to a cybersquatter (the sort that gives you their search engine results).

[Elecraft] [K3} Eterlogic VSPE 0.78
I hesitate to interrupt the flow of OT trivia but here's something that's actually useful: http://www.eterlogic.com/Products.VSPE.html This small free program allows you to create multiple connections to one serial port used by your K3. For example, my old P3 computer has one true RS-232 port on COM1 which I use for my K3. When attempting to run a second program simultaneously, it's locked out of COM1 by the first program connected. Using VSPE, I can assign COM1 to a virtual COM3, and then reset all programs to use COM3 instead of COM1. Using this I can now run the K3Utility, HRD and N1MM all simultaneously connected without any apparent conflicts.

[Elecraft] [K3] Re: Adjust TX and RX Equalizer
There is already a bypass facility for the equaliser with the synchronous data mode used for Pactor and Amtor modes, this is assigned to one of the PF keys and when in use bypasses the TX and RX equalisation. Maybe someday Wayne and Lyle will include an equaliser switching function, it could be assigned to one of the PF keys and rotate through perhaps two user defined settings and off for both TX and RX. Hopefully, the K3 will not become over complex with these various suggestions, one of the delights is the ability to use it without constant reference to the manual! 73 Dave, G4AON K3/100 #80 But I think the RxEQ should be mode specific.

RE: [Elecraft] Re: Elecraft Antennas in trees
I use an EZ-Hang and it works great, although if I had known about the tennis ball launcher first I might have chosen it instead. OTOH, in dense foliage I suspect the fishing weights penetrate much better than a larger tennis ball. I'm in forest land where the tree branches generally form a solid canopy. I do not try to pull the weights through the tree. Once over, I take the weights off and attach a line to the end in their place, then pull the fishing line with the line attached back through the tree. The attachment is carefully taped and covered to provide a smooth junction to avoid catching in branches. The line will naturally migrate toward a crotch in the branches as it is pulled, so anything that can get stuck usually will get stuck! Sometimes I use a heavy twine or cord first, then use it to pull a halyard through the tree. Ron AC7AC -Original Message- HAHA oh thats JUST what I need!!! ;) I've already got a few fishing weights up in the tree in the back yard... Its a big cedar and getting through it is a bear. So as you get part way through and are realing back those things tend to wind themselves around a branch and not want to let go.

RE: [Elecraft] dipole antenna camping trip
Nice report Scott! Where you are on the mountain can create some astonishing results; 1) If you were somewhere on the side - below the peak - you probably had significant low-angle gain away from the mountain. At the height above the ground you had your antennas, the ground nearby acted like a reflector in a beam. In this case the main lobe is not straight up, as in a NVIS antenna on level earth, but since were on a slope it was skewed down toward the horizon where it's better for working longer distances. Of course the signal is much, much stronger *away* from the mountain than through it ;-) Some dedicated mountain enthusiasts even arrange inverted V dipoles held by a single support sticking out sideways on a cliff face to enhance this effect, but it's very real even on more reasonable slopes. 2) If you were on the very peak of the mountain, the mountain itself acted like an antenna support. For the ground to act like normal level ground, it needs to extend several wavelengths away from the antenna. At our home QTHs on nearly level ground, that's a limitation. On a mountain peak, that's a real advantage! Objects many wavelengths away (like those other mountains in the vicinity) aren't likely to cause any noticeable effect. That's where Marconi and the experts of his time disagreed. Hertz had shown that a simple piece of metal would stop electromagnetic waves. What people (including Hertz) didn't realize at the time was that Hertz' waves were in the VHF range, from what later engineers could determine. They are stopped by a significant piece of metal. Marconi, after hearing his spark signals over a small hill on his family's estate, was convinced that Hertz was wrong. Marconi was right, since he was using very low frequency signals in the range of a few hundred kilohertz. I've seen the effect described in a way one can visualize as putting a breakwater - a stone wall jutting above the waves - in a harbor entrance. A small breakwater will stop the turbulent rapid (high frequency) water movement, but longer, slower (lower frequency) waves will wrap right around it and show up on the other side. The bigger the breakwater, the longer wave (lower frequency) wave it takes to pass around it: shorter (higher frequency) waves are more effectively blocked. Understanding that, and not realizing there were other propagation mechanisms, such as refraction of radio waves by the ionosphere and even the surface of the earth itself, is what led early engineers to believe that lower frequencies - longer waves - were essential for long distance communications. It was that misunderstanding that put us Hams on 200 meters and down. We were given the short waves in the mistaken belief that they had no commercial value and no one, including us Hams, would be able to get out of our back yards on such short wavelengths. Of course, as soon as we Hams discovered how effective ionospheric propagation was for long range short-wave communications, just as you did working stations on the far side of those nearby mountains, they took most of those useless short wave frequencies back :-) Ron AC7AC -Original Message- Subject: [Elecraft] dipole antenna camping trip Here is some antenna information that might supprise you! I was planning a camping trip to the mountains and needed a dipole antenna for my K2/10. I would be camped in a heavly wooded area and space between trees would be small. So before leaving home I built a 20 meter dipole because it would be short and would be easier to get in between the trees. Then I decided it would be nice to have 40 meters if I had the room, so I took two end clamps off of a battery jumper cable and clamped them to the end of the 20 meter dipole, then added enough wire to the clamps to make it a 40 meter dipole. When I installed the antenna at 8000 feet alt I had enough room for the 40 meter addition. The center was 25 feet off the ground, one end was 20 feet up and the other 6 feet off the ground. I found that with the 40 meter attachment with the battery cable clamps the antenna was resonate on 40, 20, and 15 meters with an swr of .1 on all three bands. Even in the heavly forrested area I worked stations all over the US and Canada. Just to the north of me was a mountain range that went above the timberline, but I didn't seem to have any trouble getting over it, and to the south was another that was about ten thousand feet high.

RE: Re: [Elecraft] Elecraft Antennas in trees
What you need are a set of climbing poles, which needs the poles, 3 ropes and a weight. The climbing poles are very two long rods with a hook on the end of each able to slide along each other (but not tilt !). The poles extend via two ropes, one per pole attached to the base of that pole and to near the top of the other. Then you hook the first pole over a branch. Pull on a rope to extend the second pole and hook it over a higher branch. Continue branch by branch up the tree. This contraption can carry a weight attached to a third rope with a release mechanism (a breakable tie for example). When over the branch you want, pull the rope from the correct side so the weight comes over the branch and back down to ground. The climbing contraption also needs to be tied to the rope so you can unhook it from the lower branch. After this, curse the fact you forgot to tie the aerial to the rope and start again. Hard work. It is easier to fire up a weight in a catapult. To stop leaving failed projectiles (e.g. tennis balls) in the tree, make the projectile out of ice, it will then melt. -- View this message in context: http://n2.nabble.com/Elecraft-Antennas-in-trees-tp582760p585503.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Beta test firmware instructions
Success!! Dave, G3TJP hit the nail on the head. Whatever you call the folder you created to bring in the Beta Zip File from Elecraft web site, the utility creates another folder called, K3fw2r20, for this particular beta version, when you un-zip it.

RE: Re: [Elecraft] Elecraft Antennas in trees
Dan's comment is very true of *any* antenna, and most especially tree mounted antennas. To survive storms at all, it's very important that the antenna wire or the halyards *never* fall under strain from the tree as it moves in the wind. Even small trees can exert tons of pressure on the wire or halyard. I have an Inverted L with the end attached about 50 feet up in a 60 foot high Spruce tree. Two counterweight systems maintain sufficient tension on the antenna to keep it in place while allowing the anchor point in the tree to move at least 15 feet in high winds. One counterweight allows the main antenna end guy rope to change length as needed as the tree moves and the other allows the back stay that loops over the tree to move independently. The counterweights need to be heavy enough to hold the antenna, but not heavier than needed for that. When trees whip in the winds, the inertia of the counterweights can produce shock loads many, many times greater than the weights themselves for a brief moment until the weights begin to move. The heavier the counterweight, the greater its inertia and the shock load. My antenna survived two storms with hurricane-force 100+ MPH winds last winter, although the antenna counterweight did move almost its full travel as the tree swayed more than 10 feet at the 50-foot level. This summer I adjusted the system to allow more movement. Even so, the system needs to come down every couple of years to be inspected for chafing of the lines and to move the lines somewhat if you don't want them to damage the tree. Dan's suggestion is an excellent one. No sense in starting from scratch if the worst does happen! A few feet of extra line can make all the difference in the world. If we humans have learned anything at all, it's that anything human kind can erect nature can knock down! Ron AC7AC -Original Message- ... and, HOWEVER you get the ropes over the tree, they will someday fall. If the location is a good one, you may want to use it again. Rather than trying to hit that perfect branch again, I always include an extra rope, for after the fall. The extra rope is a continuous loop that reaches the ground and does not bear any weight. It is used simply to pull a new rope/antenna up after the current one falls. It looks like I have three ropes over the branch, but one holds the antenna and the other two are just both sides of the backup loop. I usually do my antenna launching in the winter when foilage is less, but the things come down whenever they please. With a loop over each good branch, I can pull up new rope/wire even in the middle of summer.

[Elecraft] Re-loading earlier version firmware ?

RE: [Elecraft] K3 Beta test firmware instructions
The K3 Utility creates just one default firmware folder, under ...\Application Data\Elecraft\K3 Firmware. The folder containing Beta firmware is created by you, or by your choices made with the program that expands the downloaded zip file. The K3 Utility needs to know what folder you have placed the firmware files into, and you tell it that by providing the folder name in the text box on the Firmware page under the label Local folder for firmware files, either by typing/pasting it into the text box, or by navigating to it with the browse-for-folder dialog that is launched when you click the Browse... button. Creating appropriately named folders under ...\Elecraft\K3 Firmware is a fine way to retain beta versions in an easy-to-find place. But there's no magic to any of the folder names. The unzip program probably created the K3FW2R20 folder for you based on its defaults which may be dependent on the zip file name or the folder the zip file was in. If you point the K3 Utility to the same folder you unzipped the files into it should work. There's no requirement that the firmware folder be in a subdirectory of the default firmware folder. For example, the manual file transfer technique described in K3 Utility help describes using a flash drive as the firmware folder. It's just normal file system stuff, no magic is intended here! The send buttons are disabled if the firmware folder you have selected (with the above-mentioned text box on the firmware page) does not contain the necessary files to load the K3. Send New is disabled when the version of these firmware files is not newer than the firmware installed in the K3.

I just got through paying to have a new control board put in my Kenwood TS-2000 because it apparently had some ESD damage. I always disconnect my gear during thunderstorms, etc., so I assume it came in as a result of having the audio input and output and data lines connected to other equipment.

If I miss and the weight comes down where I don't want it, I detach the weight and wind the line back very slowly so as to not entangle the line. At 60 lb test, one doesn't want to create too much whiplash and catch one in the head.

The antenna crew used an air gun, similar, I think, to the ones used with tennis balls, but the projectile was a small cylinder about 1 in diameter and length, probably metal. The air reservoir was charged using a pump designed to inflate tires. A valve seemingly designed for lawn sprinkler systems was used with an electrical circuit to release the air charge into the pvc pipe barrel. The shooter did not aim for a specific branch but at a very steep angle over the top of the tree. This system had no problem getting the projectile way above the tops of tall pine trees. Due to the steep shooting angle, the projectile with fishing line also came down steeply on the other side (good idea if there is a building that you don't want to hit!). At this point the line was on top of several branches, big and small. The shooter would slowly pull the line back, directed by a second person with the projectile in view. This way several small branches were cleared without snagging the projectile. When the projectile was hanging down from a sturdy branch, the line was released to get it down to the ground.

Re: [Elecraft] [K3} Eterlogic VSPE 0.78
Very nice. Looks a lot lie the bridging program being developed for the LP-PAN. Will have to check this out. I get around it by running rig control and spotting (ACLOG) for most of my activities. Then N1MM by itself or with MMTTY for CW/SSB/RTTY contesting. MMTTY is setup to run on VOX, and CW for N1MM uses the serial interface. I haven't transmitted PSK yet. Have played with Digipan and HRD. HRD is very provisional and all-in-one. Lots of neat things it is cable of doing, and the superbrowser is cool. But I haven't taken the time to sit down and sort it all out yet. David Wilburn K4DGW Bill W4ZV wrote: I hesitate to interrupt the flow of OT trivia but here's something that's actually useful: http://www.eterlogic.com/Products.VSPE.html This small free program allows you to create multiple connections to one serial port used by your K3. For example, my old P3 computer has one true RS-232 port on COM1 which I use for my K3. When attempting to run a second program simultaneously, it's locked out of COM1 by the first program connected. Using VSPE, I can assign COM1 to a virtual COM3, and then reset all programs to use COM3 instead of COM1. Using this I can now run the K3Utility, HRD and N1MM all simultaneously connected without any apparent conflicts. Please do not contact me about setup questions. 73, Bill ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 CW spot feature
I ended up playing with some of the AGC / audio settings, as I had not messed with them, since I initially played with them when I got the rig. But CWT is working fine, used it a lot yesterday. I did notice initially, after the firmware update, that I adjusted the threshold a notch or too, but that is all it took.

[Elecraft] Elecraft CW Net Report for July 27th 28th, 2008
Good Evening, Wow, that was noisy! My ears are still ringing after my walk. Tomorrow's chainsaw work will seem pleasant in comparison. Trying to find the weak signals on 40 meters was not easy. It did not help that I kept hearing dits and dahs in the noise. I did hear a few requests for my rain to move further south. Seems like the weather in California is above 80 degrees. I have only seen the temperature that high a couple times this year. This week it is still raining every morning with sun coming out around noon. I will have enough wood ready for two years soon if this weather keeps up. The prediction is for mid to low 70s until Thursday. This is probably why the QRN is so high. Luckily during the Flight of the Bumblebees it was not so bad. I tried all of the bands but only 20 and 40 meters gained me any contacts. Still learning N1MM which is much nicer than paper logging. Much nicer than any other logging program I have ever used too! The approximately 400 pages of documentation is too much to work through so I take it a little at a time.

I will also pack all the material for the roof up there now so I don't have to do so when the temperatures are in the 80s. I expect it will get warmer when the dry season gets underway but that has yet to happen. Fireweed just started blooming if that gives you any idea of the season up here.

RE: [Elecraft] ESD Damage Question
I suspect that the K3 does not have any design features for minimizing susceptibility to ESD. The K2 apparently does not. When I moved to NV from CA I had a rude awakening. The humidity here is low, often in single digits. I always draw sparks to every piece of metal, e.g., light switch plate screws. I found that the K2 would go into hyperspace and require an off/on reset whenever I reached for it and drew a spark to the case. One day I sparked to the case containing the KPA100 and KAT100 and the amp stopped working properly. The firmware probably got zapped. I restored function by putting in a new firmware chip and bringing all the mods up to date. Since then, I have grounded everything to power ground and have an operating table with conducting paint (Walmart). It is now easy for me to keep discharged to the table. Nonetheless, the K2 still burps if I happen to spark to the case, even though it is well grounded. My K3 was set up with great care and attention to grounding, but I expect that it may also respond to case discharges. I sure am going to try to avoid testing that surmise! Jerry AI6L -Original Message- From: Mike Thornton [mailto:[EMAIL PROTECTED] Sent: Sunday, July 27, 2008 2:30 PM To: elecraft@mailman.qth.net Subject: [Elecraft] ESD Damage Question I have my K3 on order, and plan to take all of the standard ESD precautions when I build it. My question is about after it is built and in operation. I just got through paying to have a new control board put in my Kenwood TS-2000 because it apparently had some ESD damage. I always disconnect my gear during thunderstorms, etc., so I assume it came in as a result of having the audio input and output and data lines connected to other equipment. I would hate to have a repeat of that situation with the K3. Does anyone have any thoughts about the K3 and static damage or any special precautions that should be taken?

RE: Re: [Elecraft] Elecraft Antennas in trees
I've gotten my fair share of storms here too and rather than go the route of counter weights since I had to kinda skirt the side of a big cedar I opted for a rope method. I ended up tying two ropes together at the center point of the dipole. Then ran the rope up into the trees. The rope bears all the force (and it can take some HEAVY beating). Then the antenna is simply hung from the rope using crossed zipties around the spreaders (its a fanned dipole). This has lived through some pretty hair situations. I did lose a few feet of elevation one year but that was because the tree lost a limb and I fell down to the next branch! hihi. ~Brett (KC7OTG) On Sun, 2008-07-27 at 22:16 -0700, Jim Brown wrote: On Sun, 27 Jul 2008 11:47:54 -0700, Ron D'Eau Claire wrote: The counterweights need to be heavy enough to hold the antenna, but not heavier than needed for that.

[Elecraft] Sidetone Monitor Preference Opinions
Just out of curiosity what do you gentlemen prefer? Do you like things better the way the K3 does things where the monitor level is a fixed output regardless of the AF knob. Or is the way the K1 does things more preferred. The STL menu entry allows one to set the side tone monitor as an offset from the RX level. So you set the monitor level and it gets louder or quieter as you adjust the AF Gain. My personal preference is the K1 method. I like this because if my wife is sleeping then I like to turn down the volume (if not go all the way and use headphones). I like to have the sidetone go down as well rather than make a separate adjustment. I'm not asking for any changes. Just curious to hear the thoughts of others on this topic. ~Brett (KC7OTG) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
