[Elecraft] KXPA100 Utility v1.14.11 CONFUSION and HELP!
New KXPA100 (with 100w internal ATU) for KX3 owner. I have the KX3 and KXPA100 hooked up with the Elecraft supplied cables. In the Amplifier section of the utility, when using the KXPA utility, why is the PA Bypass box checked? I understand the Attenuator box being unchecked. In the Anntenna Tuner section, the Tune button (on the right) does not tune the rig, it just causes the 25w LED to blink. No noise is heard from the ATU. I have to physically hit the ATU tune button on the KX3 to retune. Finally, in the same Antenna Tuner section, why is the ATU Bypassed check box (below the Mode options) checked when the Mode box is set to Auto? I’m doing something wrong, please help this newbie.

Re: [Elecraft] KXPA100 Utility v1.14.11 CONFUSION and HELP!
Good morning, Dave! PA bypass is controlled by the KX3 power setting and ATU tune. If you have selected a power level below 10 watts with the KX3 power control, the KX3 bypasses the amp. The PA is also bypassed during ATU tuning. If you don't have the KX3 in PA mode ON and the ATU is not tuning, the PA should initialize in not bypassed at power on. In PA mode the KX3 power control should go up to 100 watts or so. Pressing the ATU tune button causes the KXPA100 to begin tuning. It blinks the 25w to indicate tuning in progress. But now it needs a few watts of steady RF to measure SWR. You need to turn on the transmitter at this point. The amp TUNE button is intended mostly for transceivers other than the KX3. With the KX3, with PA mode on, the KX3 sends a command that effectively presses the KXPA100 TUNE button, then the KX3 turns on its transmitter, and the ATU steps through relay settings. The KX3 periodically asks the amp if it is done tuning, and when it is, the KX3 stops sending carrier. If you don't have a KX3, or choose not to use the connecting cable or PA mode is not ON, then you'll need to somehow key the transmitter to provide a few watts until ATU tune completes. The ATU is bypassed if the match is good enough without the ATU. If you tune into a dummy load, often the best setting is ATU bypassed. My 20 meter antenna offers a very low SWR in the low end. But in the phone band the SWR rises. I have tuned at several places in the band. At the low end, the best tuning solution is bypassed, and that tuning solution is memorized so when I return there it selects that setting, in mode MAN, based on a frequency count. In the phone band, the tuning solution uses tuner reactances to show the amp a low SWR. After you have tuned the ATU in several places in the band, I'd recommend you switch the ATU to mode MAN. 73 de Dick, K6KR On Jun 29, 2014, at 2:36, Esquer Dave dave.esq...@gmail.com wrote: New KXPA100 (with 100w internal ATU) for KX3 owner.

[Elecraft] Radials for vertical
Most people would think we're well into Summer. Not here in the High Rockies. Summer here has just begun. Time to mend some fences. Now the point: I just pulled about a mile of #11 soft drawn aluminum wire - mostly in 50' to 100' lengths. Normally its electrified and the cattle won't touch it. But last year the charger died and the cattle just shredded the wire to get into my grassy meadow. So now I have all this aluminum wire that I would hate to throw away. So I'm thinking of making a really good ground plane and putting up a vertical of some kind. I have enough scrap tubing to make about 38' or so. I was thinking of putting a remote tuner at the base of the vertical as the length of coax to reach it will probably be at least 150'. So I'd be interested in comments on how to configure the radials in terms of length and number. I know there's some guys on this reflector that real know a lot about this sort of thing.

Re: [Elecraft] Radials for vertical
HI Doug: I assume you are talking about a vertical mounted on the ground. If so, you might want to consider extending it a bit to 43 feet.. some feel that length works well on bands from 80 through 10 meters. I'f not ever done that, so I don't know. But I have used base loaded verticals in years past. Some have said for a ground mounted vertical, you need at least 16 radials. If you can make them as long as the vertical, that'd good, but even half that size is good. More radials is better. And length is not critical.. so you can just use whatever sizes you have. If you elevate the radials... then length is critical, and you would want four radials every 90º for each band of interest. Glad to hear you want to put that AL wire to good use. :) 73 de Ray K2ULR On Jun 29, 2014, at 3:07 PM, Doug Person via Elecraft wrote: Most people would think we're well into Summer.

Re: [Elecraft] Radials for vertical
There is a lot of work on number and length of radials. You can get a good ground with anything from 16 1/4 wave radials to 120 1/10 wave radials buried. Elevated 1/4 wave radials work well with only 2, though 4 is nice. The experiments on this are either in the ARRL Antenna Book or the ON4UN Low Band book. I'll try and track it down. You may have rocky, low-conductivity soil, so radials could be much more important. wunder K6WRU On Jun 29, 2014, at 12:35 PM, Fred Jensen k6...@foothill.net wrote: On 6/29/2014 12:07 PM, Doug Person via Elecraft wrote: So now I have all this aluminum wire that I would hate to throw away.

Re: [Elecraft] WTB: KBPF3 Gen Cov Module
David, Actually, aluminum will hold up OK in many soil conditions - although in highly acid soils, it will become rather brittle. Squirrels and other rodents chewing on the aluminum wire is more of a problem. So my conclusion is that if you want in-ground radials that will last for about 3 years, you can save over the cost of copper by using aluminum - make your long term choices depending on your ham budget. If you are using elevated radials, aluminum is great - but put them high enough so that humans, deer and other animals can pass under them without harm to the radials or the beast. If you are in an area where riders on horseback could pass, use plentiful warning signs. My criteria is 10 feet above ground, but yours may vary. I have lots of trees (we live in a forested area) , so buried radials are not practical due to tree roots, so I use electric fence insulators attached to the trees to support elevated radials. For a good source of aluminum wire, look to suppliers of electric fence wire. I use the 17 AWG size for my radials. 73, Don W3FPR On 6/29/2014 5:13 PM, David Christ wrote: I have been told that aluminum does not last very long in contact with the ground.

Aluminum/Copper Alloys do not last long in the presence of Sodium Chloride which is present in most soil and plentiful in most water, particularly runoff and sea water.

[Elecraft] Ouch
So about 20 minutes prior to starting another successful Field Day with my trusty K3 I powered it up for the first time after connecting everything had just started some tests when my buddy starting yelling that I was letting some of the magic smoke out of the radio. Sure enough, there was smoke coming out of the back of the radio. I dived over and pulled the power. To make a long story short, I was running an S9 31' vertical antenna base tuned with an SG-231 autotuner, with the auto tuner powered over the coax using DC blocks. The exact same config as I ran with last year with wonderful results. Unfortunately this year in my excitement I carelessly installed the DC block at the radio end BACKWARDS, sending the 13.8v from my 30 switched supply right into the antenna jack. After the incident I powered back up with my finger on the off switch to try to assess the level of damage. The radio puts out some power, but the SWR is infinite even into a dummy load. I am not sure of the status of the receiver input chain as I didn't want to put it back onto a real antenna. So I am just wondering before I open it up what kind of damage I might find and what kind of options I might have for repair. Has anyone heard of this sort of a bonehead mistake? Any ideas on what I might have fried? Given this is a mechanical assembly only kit is there any chance any of the parts are going to be user serviceable? I love the radio and I'm hoping it is at least salvageable.

Re: [Elecraft] Ouch
Mike, I am sorry to hear that you had such an incident.Unfortunately, you may not be alone in your woes. Such events are not uncommon among Field Day reports. The basic K3 is protected by a series reverse protection diode, and should be OK. Unfortunately, there is not such protection for the KPA3 because the added 0.3 volts drop of a diode rated at 20 amps is not practical. I would expect that the damage is restricted to the KPA3, and may require replacement or major repair. Contact customer support at k3supp...@elecraft.com to review your repair options. There may also be damage to your SG-231 autotuner as well, but Elecraft customer support cannot help with that. Try the K3 working into a 50 ohm dummy load and see what the results might be. Elecraft can help with analysis of the damage for that part of your problem. 'Closing the barn door after the horse is gone' is not really helpful, but I would advocate the use of Anderson Power Pole connectors with fuses right at the power supply end of the power cord as prevention for the future. Properly constructed APP connectors are 'genderless' and can help prevent such incidents. I just returned from Field Day operation with 2 of my Elecraft rigs with no problems, but I use APP connectors on each piece of the 12 volt supply for all my gear. One gentleman at the Field Day site used one of my power supplies to power his Omni, but he did not use APP connectors in his system. I gave him the power supply (with APP connectors) and allowed him to change the connections to the power supply output at his own peril - fortuntely, there were no problems. In my system, the power supply is fused within inches of the power supply end (both the positive and negative leads with fuses rated for the wire size used in the cable - see AWG tables) and all the rest plug into a Rigrunner or other distribution box with fuses rated for each branch. The fuses should be sized for the smaller of the wire size in the power cable or for protection for the gear on the 'business end' of the power cable. I fuse #12 power cable to a 100 watt class transceiver at 25 amps. 73, Don W3FPR On 6/29/2014 11:23 PM, Mike Lewis wrote: So about 20 minutes prior to starting another successful Field Day with my trusty K3 I powered it up for the first time after connecting everything had just started some tests when my buddy starting yelling that I was letting some of the magic smoke out of the radio.
