Re: [Elecraft] KX3 internal battery problems
I think you will find that one of the cells used in this series arrangement will have a high internal resistance. You also mentioned a brand that I have seen the worst performance from (my personal experience). I have been using one of the Blue ESR meters (80 bucks) for about 4 years to look at batteries that don't perform well, high resistance in a cell has always been the issue.. Before all the engineers jump on and say there is a difference between resistance and impedance and I don't understand, and this is not the correct way to read internal resistance. I can say that I also understand how to load a battery and at the same time and take a resistance reading of the cell. But who has the time.. I have no intent of testing in a laboratory, when the shop is sufficient. First off make sure you don't use any of the really expensive ESR meters that measure the voltage first and if they see any the go into a capacitor discharge cycle.. that would not be good. I simply hook the battery across the meter and read the resistance.. While this is not a exact laboratory measurement you can tell a lot from the reading.. look at each cell in the string, if one is higher just get rid if it you will see an improvement of string capacity. As an example not long ago I had a battery pack that could last about 5 minutes after it was charged.. reading the whole pack's resistance it showed about 9 ohms of resistance on a 14 volt pack. opening the pack I found two of the cells bad.. one measured 2.5 ohms the other was 3.1, that is 4.5 ohms just from two of the batteries.. the rest were around .85 ohms.. I have also tested thousand of SLA batteries this way, and can tell you instantly if the battery will deliver the rated capacity.. from experience if a cell is more than .8 or .9 I don't use it.. Regards.. Fred I had to post this message two time to get it to the list..

Re: [Elecraft] KX3 Vehicle mount
Brian, if you run the negative lead all the way to the battery (direct) fuse the lead close to the battery. If you run the negative lead to point that ends in a frame ground do not fuse the negative lead. This does not conflict with standard automotive manufacture recommendations. Also carefully read almost all manufactures installations it says run the leads to the battery, and they provide two fuses on in the positive and negative lead. I have not seen an installation manual in years that didn't say directly to the battery.. Tom W8JI has some good explanations on they why's and how this came to be http://www.w8ji.com/mobile_ground.htm Regards..

Re: [Elecraft] KX3 Vehicle mount
I will add to the conversation with a direct story relating to radio grounds, in this case it was a sail boat... At one time I spent much of my life Surveying boats, another survey friend asked me to look at his sailboat as he could not keep zinc's on the boat they would last about a month.. An arriving throwing a silver anode over the side (in salt water) showed about 1.75 volts between the water and his ground. So that is why the zinc's were plating off of the boat. All grounds on the boat lead to a grounding plate at the foot of the mast (42 foot). As I was disconnecting each ground wire on the grounding plate, suddenly the ground went away, and Lee said "the VHF radio went dead", it was on as he was listening to the weather. So what had happened.. This was a case where the radio was wired directly to the battery, with fuses in both the positive and negative leads. The fuse in the negative lead was indeed blown (unknown reason). The ground path to the radio was up the coax shield to the masthead antenna, this antenna was DC grounded flowed then down the mast to the ground plate. This connection raised the ground potential in reference to all other grounds 1.75 volts.. and was the cause of all of the problems. Properly grounding the radio ground to the ground plate permanently resolved the issue.. This was a case of small currents (radio in receive), however should a starter have been involved as Tom (W8JI) explains the currents would have been great and could easily have caused a fire. My point is where ground connections are made can have consequences.. Regards..

Re: [Elecraft] Small QRP antenna
With an end fed 1/4 wave you only need a counterpoise that is about .05 wave length. it can be the coax or another counterpoise. Although a counterpoise has some effect on radiation pattern of a quarter wave radiator, it is minimal. You won't see much improvement in performance by going above .05 wave length.. it's not worth the trouble to increase the counterpoise length..

Re: [Elecraft] Small QRP antenna
Jim, almost everyone on the list immediately noticed that I accidentally typed 1/4 when I actually meant to type 1/2. They most likely noticed it because the thread has been almost 100% about 1/2 end fed radiators. The person I replied to specifically asked about adding a 1/4 wave counterpoise to a EFHW antenna. It appears that you deleted the part of the message I was replying to and only kept the portion you wanted everyone to see.. My response (this post) has nothing to do with my miss-type (we all oops sometimes) it has 100% to do with making sure you have not confused anyone on the list into thinking an EFHW is the same as a 1/4 wave radiator.. BTW I 100% agree with everything you said about 1/4 wave radiators.. I absolutely do not agree that ground losses are the same on 1/2 wave radiators as they are on 1/4 wave radiators.. Discussions about current node locations can be had another day.. Keep spreading accurate knowledge, everyone needs it, just make sure the knowledge you spread applies to the subject.. otherwise it creates even more confusion.. Regards..

Re: [Elecraft] KX3 - AFSK RTTY
Keith, I have been on unix for the last 30 years, and fought with cocoModem for about 3 months, and finally came to the conclusion that it is not ready for prime time. I would get it working for several weeks, then it would quit.. I never got it to talk to my logging program even with applescript, finally I moved to fldigi with logging and rig control coming from rumlogNG and have never looked back... This gives more modes than cocoModem supports.. I use both a signalink, and a small 7 dollar usb sound card depending on my location (home/portable). I could use the existing soundcard in the mac, but just havn't build up a cable for that to work yet..

Re: [Elecraft] kx3 px3
Fred: Turns out I had already read everything you suggested, and did correctly understand the compensation, however... -73dbm at the antenna, signal generator only (no noise) does =S9 on the KX3, and does not = -73dbm on PX3 (Lvl Mode = scale:db) Per PX3 manual page 23 bottom right paragraph 5th sentence down: "The indicated dBm level should be the signal level at the signal level at the KX3 antenna input" In my case this is not true, I am seeing about a 10-12dBm difference. In my previous post, I referenced S9 and 50 microvolts, thinking most people on the list are not use to referencing dBm, that was my error. After re-reading my original post I even said mV when I intended micro.. I should have been more specific, and correct.. I do not expect the PX3 to be a precision instrument, however I am trying to resolve and understand a 10+db error here, huge to me, which should not exist according to the PX3 manual, but may be in the PX3 specification if its specification is +-10%. As a side note the PX3 scale does appear to be linear, relative to dBm, i.e. the error is the same through the usable scale.. If that is normal I can live with it, I simply want to understand if this is what others are seeing.. and make sure this new to me PX3 is operating correctly..

Re: [Elecraft] KX3 tuner getting stuck at 25.4:1 SWR
Sorry for the late response.. I had the exact problem several weeks ago. Every time I removed the batteries the problem would be resolved.. The problem was ultimately me being a dumb ass.. I had purchased a nice blue tooth speaker that perfectly sat on top of the KX3, however it kept sliding off. My solution was to glue a small round magnet on the front corners on the KX3 top. I also glued the same small magnet on the bottom of the radio. Well guess what, I knew better but didn't even think about magnetic shielding of the inductors in the ATU. While testing everything was fine, when I was convinced everything was ok I would place the radio back in it's operating position everything was still ok even with speaker on top, as long as I was on 20 meters, as soon as I went to 40 which could be a couple of days later.. the radio again went to 25.4:1 One magnet was not enough to do it, but when both magnets were on the top right hand corner, it was all over for the ATU.. makes 100% sense now that I know what was happening...

Re: [Elecraft] Is it my KX3/antenna or is it lousy band condx?
There has been a happening in the last 15 or so years. It seems that every antenna is "the best we have ever had" this statement is directly proportional to the number of people who study theory to those who just read others comments on the internet. Or as some say, the SWR is 1:1 so its a great antenna. BTW I love my dummy load for EXACTLY that reason. I can clearly say that I have had enough different antenna's over the last 35 years that I know what is a good antenna and one that is not.. plus I even understand most of the theory. Today a new ham dumps 125-150 bucks in to a 5 dollar pre-manufactured wire antenna, and says, this is the best antenna around even if he has never used any other antenna. See how good it works I even have an S9 noise floor, no other antenna is this sensitive, when all the wile he is running 30db of preamp he does not need. Simply amazes me.. that some think they even have enough education or experience to even have a meaning full opinion.. but away they go on eham or qrz about how good something is. Lucky most on Elecraft don't all into this category. We do have many good radio related sites out there, examples are those who show current band conditions, low power reporting sites to check your own propagation etc.. those we should learn to use as they are meaningful but don't assume the to be 100% all of the time, I remember many years ago when I was elmering a new ham, he built a 15 meter beam, when he decided after one week that the 40/15 dipole I built for him was just not working, I loaned him a HW16, he complained for weeks that the something was wrong, I went over one Saturday to see what actually was wrong, a spin across the band showed no signals, one CQ with 50 watts and from Ohio I was the pileup of European stations, I worked about 5 contacts, looked at him, and said, "So what is wrong", he says.. "what knob did you turn when I wasn't looking" did you ever call CQ "no says he" "I think you need to actually use the radio before you decide something is wrong" says I. If the band propagation sites say the band is dead, and your radio is not hearing anything, most likely it is not your radio or your antenna. If you are hearing S9 noise and unhook the antenna and it goes away, I will make you a bet that your radio is not broken.. And yes all of the switching supplies didn't exist 20 years ago, so we need to do things we didn't have to do before with toroids and other things that we didn't do before, there is even some noise sources we can't fix as others are legally generating it. Me thinks the days of a usable -127db noise floor are few and far between, thanks mostly to what our government is allowing to happen... FWIW/WYP.. regards..

Re: [Elecraft] OT: Inverter type generators used for FD?
When you evaluate generators look at the continuous load that is what is important. Lets compare two Honda units as an example the 2000i and the 3000i. The 2000i is rated at 2000 watts for 10 minutes and 1600 continuous, while the 3000i is rated at 3000 watts for 10 minutes and 2800 continuous. Purchasing two 2000i with a slave kit (48 bucks) will run you 1900 bucks and give you 3200 continuous, while a 3000i will give you only 2800 continuous, you also get to spend 500 bucks more for the 3000i. The 3000i is 131lbs, while each 2000i is 47lbs each. I can move two 47 lb units by myself, a 131lb unit is hard on us old people. It is much more flexible to have two and only pull out the second one when you really need it. one drawback, the 3000 is quieter then two 2000i by a few db's. Two generators also burn lightly more fuel, but you may also be able to run two in economy mode, while you would not be able to run the 3000i in economy making up for the difference in fuel. I also have found no reason for any type of filter with Honda's.. additional savings. Also note that one brand the noise hash was being emitted directly from the generator not the power line, a filter won't fix that one.

Re: [Elecraft] OT: Inverter type generators used for FD?
Over the last several years we have tested about 6 different brands of inverter generators. Hash on all of them except the Honda's. I have not seen any hash on the 1000, 2000, or 3000 generators. One brand had hash over +20 on 40 meters. It was coming directly from the generator, not the power line cord, moving it out from the trailer on a 100' cord reduced the hash to around S6. Of course Honda's are the ones everyone else is trying to beat with a lower price point. You only get a lower price point one way in a competitive market, make it cheaper. Just purchased a 2000i from Mayberry advertised in QST for 929 free freight and sales tax to me here in Florida (no relationship). 150 bucks cheaper than anywhere else I could find it. Regards..

Re: [Elecraft] OT: Inverter type generators used for FD?
Jim; When using the Honda's I have no experience of relative location to the antenna's causing a problem. Also I am absolutely sure no one on this list would expect to hear noise below the noise that is below the noise when they already had a high noise floor for other reasons, and they are already hearing noise from the high noise floor not caused by the generator they could not hear because of the already high noise floor they already had before the generator noise floor was generated below the noise floor. All of my testing was done with places far removed from the mains, that is why I need a generator to start with. The generator I alluded to that was generating extremely high hash, was generating it without anything plugged in, not even an extension cord, the hash did not diminish when you placed it on a load either, so it was NOT common mode. That generator was the Generac Inverter (3 different ones) that is competing with the Honda. BTW I consulted your web site, and didn't see any references to the how far a generator must be kept from the antenna's, Please add a reference for all of us so we know when we will have a problem, we may not be able to move it without advanced warning of the problems it might cause. If anyone on the list is hearing noise from their generator that is below their normal noise level, please let us know.. so we can get it documented on Jims web site. And I still don't need a common noise choke you designed, so don't think I will build one, no matter what the mechanism is. Regards..

Re: [Elecraft] Keying CW in SSB Mode
Ted, it's not a great strategy any time, and yes most likely that is what was going on. You should see their signal when they have RF on the audio or a hum. Not exactly meets the FCC requirements. If you are listening with a wide filter some times you even get to hear their Microsoft Windows generated tones if they forget to turn them off. Let the flood gates start with all of the "you can't tell the difference so it's ok" But I can and have seen it many times with bad signals.. It's not CW keying, its USB or LSB keying with a single tone.

Re: [Elecraft] OT Learning Morse anew
I am convinced that the barrier most folks have is from bad habits that allow you to unconsciously learn double and triple conversion in your head. when you are slow.. hear the sound, count the elements, determine what it means, then convert to writing.. I am 100% convinced that doing anything to fix that problem is the only solution to the problem.. My real life story, which has been applied to multiple other people and has fixed the problem in most cases.. Back in the mid 70es I was trying to break the 13 WPM barrier to get my General License.. I was working several stations per night but not getting anywhere with my speed.. A friend at work who was not a ham, but taught CW in the Army finally heard from me enough and said "are you free tonight and do you have a code practice oscillator" I did so over he came.. He grabbed a book from the shelf, handed me some paper and said.. I am going to transmit at 15WPM for the next 15 minutes. I want to you write each letter down, don't worry about the mistakes I don't care about them.. I will not stop. After the 15 minutes he took the paper and started writing down letters... He only wrote down the first letter I missed in a string when done he said.. you are double translating in your head and there are 6 elements you really don't know. So after a cup of coffee, he sent me those 6 letters for the next hour at 20 wpm, no writing only saying the letter out loud as I heard them. Spacing was also fast.. no farnsworth, don't even think it existed them.. if I had it wrong he didn't say anything, he just kept repeating the character till I had it correct then he went on. after a break, we then spent another hour doing the same thing with all other elements and then he went home. The next night he came over and I not only was at 13wpm but could write at 18 wpm 100%. then he said.. now get on the air, from now on you are only allowed to write name, call, address if sent, otherwise copy in your head..you now know all elements of the code, if you are writing you are translating from ear to mind to hand, you do not want to translate at all, anyone is capable of writing from memory without stopping to translate.. problem fixed.. and have been enjoying CW since then.. I have used this method about 10 times myself on other hams, and in all but one case the problem was fixed... the moral.. listen to faster code than you need, and put down the pencil and paper..

Re: [Elecraft] Counterpoises and Grounding
Jim, lets stop talking about grounds totally when dealing with RF, it's just a confusion factor when it comes to discussions. unless we are talking about as NEC and others when they correctly call it a "Safety Ground" or a "Grounding Conductor" and make sure that everyone understands the difference.. most don't discussions should be about Safety Grounds, and grounding conductors 100% about 60 cycle and DC currents common connection points 100% about how the above are connected counterpoises, radiating elements: deals 100% with RF and antenna's etc.. properly understanding each one and you won't be confused at all.. I also disagree with your statement "First, and most important, for lightning protection and electrical safety." The first and most important item is an electrical Safety Ground as it protects people, they can't be replaced. Second is lightening protection, as it typically protects equipment. equipment can be replaced They don't carry the same weighting factor.. as very few worldwide are killed from lightning vs improper safety grounds. most likely the only thing we don't agree on.. everything else you seem spot on...

Re: [Elecraft] Counterpoises and Grounding
Jim please accept my apologies, I didn't realize that since you have written extensively on the subject and actually had a website that no one else is allowed to comment without being chastised for contributions. I have made myself a note to never reply to any conversation you are currently or could possibly become involved in , as all authoritative answers have already been provided on your web site.. and absolutely nothing else ever need be discussed. and again I must disagree with you. when you state that "I think what you view as disagreement is my failure to write well enough." you write extremely well, your condescending attitude comes through very clear, to everyone.

Re: [Elecraft] PX3 interfering with rig control to KX3?
Bill, I use exactly the same setup, and I just verified mine is working, even after "High Sierra" upgrade. I had that problem when I first set it up and the problem was in the Serial speed in RumlogNG in my case. My speed in rumlog was differtent than the speed on the PX3. Since it goes there first before the KX3, The PX3 will not pass the bad baud rate date to the KX2, I set all of my speeds to 38,400, RumlogNG, the PX3 and the KX3.. hope this fixes your problem also..

I quit contesting when about 5 years ago, when I walked into the 20 meter CW station at field day to relieve someone, I found 5 guys who could not copy any CW at all, averaging 140-150/hour one was watching CW skimmer and clicking on the calls, one was sending call/599 with keyboard and one was logging with another keyboard. The other two were there just in case someone got tired of typing.. All at the same time they were telling jokes and drinking coffee. I'm out of here says I, I still work FD, but refuse to work a CW contest, yes 30 meters is your friend on contest weekends Fred Moore email: f...@fmeco.com wd8...@gmail.com phone: 321-217-8699 On 11/27/17 10:30 PM, Ron D'Eau Claire wrote: > I certainly sympathize with your feelings Fred.

Re: [Elecraft] CW Contest and Elecraft K3s decoder
Not a looser at all.. I'm quite happy to not play in the robot CW pool. Most of the time these roboCW guys leave their rig off, except during the contest, so life is very good for the rest of us. BTW sorry I didn't consult you before I posted my comments.. I'll try to do better in the future... I bow to your cow dung, and those who you know, who most likely sit in the dung you fling.

Re: [Elecraft] CW Contest and Elecraft K3s decoder
CW skimmer can copy almost anything. I will not play in their sand box... I think we need a good contest where each ham sends an actual RST he copes, and a personally designed 3 alpha numeric check sum. The check sum get published when he/she turns in their log. The logs get computer compared any call where RST and Checksum that is copied correctly during the exchange gets 5 points anyone that is incorrect looses 100 points for that QSO. The contest sponsor should be putting out false calls and frequencies on the frequency spotter list, if any of those calls show up on any list the whole log gets tossed and their name published as a cheat.. There should also be people who only call CQTEST and never answer a call, if there call shows that log is also tossed. I have not use for CW decoded qso's as a learning tool or otherwise.. off my soapbox Fred Moore email: f...@fmeco.com wd8...@gmail.com phone: 321-217-8699 On 11/27/17 5:53 PM, EUGENE GABRY wrote: >> On November 27, 2017 at 2:39 PM Fred Moore wrote: >> >> CW contests have >> become a machine contest not a Ham contest... >> > > This is something I fight personally when I decide to enter a CW contest. > Technology is great, it has allowed those who are either not proficient at CW > or can't even copy CW, to be able to communicate. > > I've always thought the focus of a "conTEST", whether CW or SSB was to test > the capabilities of the "operator" to accurately receive the information > sent, making as many contacts in the time period of the contest as possible. > Scores determined in part, by busted calls or other information copied > incorrectly, and then scoring against their peers. > > > Today there are a lot of (Robots) that can decode CW.
