[Elecraft] KX3 beta firmware rev 1.87-better AM BCB sensitivity
I installed beta rev. 1.87 and selected the BCB=160 and observed my local AM station on 920 KHz go from S8 to S9+5 with PRE on set at 20-dB. I then tuned down to 495 KHz and am able to see signals at S9 that were at noise level before! Noise floor is S6 with BCB=160/PRE ON. With BCB=NOR everything is S0 at 495 KHz. This quick test was into my 80m inverted-V and not the 600m inverted-L (which needs repairs). 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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
Re: [Elecraft] K3 - No speaker output
Mine failed with a stereo (not a mono) plug which had been inserted prior to the K3 being powered on. The external speaker of 8 ohms was wired onto the left channel (plug tip), therefore the right channel did not have a load at the time. Don't know if this causes a problem. The fault occurred when the AF gain on my K3 was advanced to approx 12 o'clock, at which point the audio out the speaker failed. So, the fault was NOT caused by shorting either of the outputs, or plugging in the speaker with the K3 powered on. My K3 is an early Ser # 307 73 Stewart G3RXQ On Tue, 14 Jan 2014 19:10:29 -0700, Dave Hachadorian wrote: Putting a mono plug into the stereo jack is not the ONLY failure mechanism for the speaker amplifier chip.

That will cause failure of the audio amp for the speaker. Later K3s (I don't know the serial number) have protection for that shorting condition. The best protection is not to put a mono plug into the speaker jack. If you want mono, cut off the mono plug and connect only the tip and shell to your speaker - the ring does not connect to anything. 73, Don W3FPR On 1/14/2014 6:55 PM, Richard Solomon wrote: Can someone explain to me exactly why the chip failed, and what the Audio Protection Assembly is for ?

Re: [Elecraft] Requirements for keying a KXPA100
I got a variety of suggestions, and decided to go the easiest route (since it worked) of removing the current limiting resistor and switching the diode to a schottky diode. The extra diode is required in my case because the PTT also keys an internal TX preamp whose keying circuit is run on 13.8V. Without the diode this circuit (unless I chose another suggestion of creating two separate PTT drivers on the transceiver) would see the floating 5V in the KXPA100 as a relative ground, so just connecting the KXPA100 key line would have caused the internal TX preamp to be keyed. It was clear that a current limiting resistor was not required for either the internal TX keying circuit or the KXPA100 (they key current is about 1 mA for each of them). I decided if a current limiting resistor is required for keying another amp I can build an external adapter cable that includes the resistor for that use case. With the schottky diode in place the Hermes transceiver pulls the KXPA100 key line down to about 0.39 volts, which should be enough to trigger it with hopefully a comfortable margin. Everything appears to be working properly now, so now I get to play! Anyway, thanks to all for the helpful suggestions. 73, John AC0ZG __ 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

[Elecraft] K3/KPA500/KAT500 SWR Problem WHITE SMOKE!
I am pleased to relate that I seem to have finally nailed this problem, and I think many of those who gave me helpful advice and the Elecraft design team will be interested in learning what the final diagnosis and cure turned out to be. A quick recap: About 2 months ago, operating at about 75W into my trusty OCFD, the KAT500, KPA500 and K3 SWR readings shot up into the red and all DX fun ended abruptly. The problem remained, so I started looking for the culprit: I pruned tree branches that were touching the antenna after a recent storm. No joy. I replaced my 300W 4:1 balun at the end of my RG58 buried coax feeder with a 1KW unit. No Joy. I replaced the buried RG58 feeder with UR8 which took a new route, avoiding burial. No Joy. I dropped the antenna and replaced the 300ohm twin feeder from the balun to the T piece, the T piece itself and the antenna wire and dog bones. No joy. At this point I consulted the Reflector Oracle, and the most common response was common mode current on the feeder caused by OCFD unbalance. I did research and decided to build the renowned GM3SEK choke balun. I chose the mid range version which covers broadly 5-14MHz and installed it just south of my 4:1 balun at the North end of the feeder. No Joy. Further ideas from reflector pundits suggested that it might still be common mode, but coupled from the antenna into the feeder where my GM3SEK choke wouldn't help. Fortunately I had bought enough Fair Rite oval cores to build all three (Lo/Mid/Hi) balun designs, so in a final roll of the dice I built the two core Hi Band balun and installed it in the Shack next to my rig. The hi band version has a fairly flat impedance curve and reaches down to 7MHz and up to 30MHz. IT WORKED! I have run 100W on all the bands from 40m to 10m and I have seen no run away SWR readings. My 25W tune value stays rock solid. As a final push-my luck step I turned the KPA500 to operate and ran 400W SSB. No Sweat! All of these things were no-nos yesterday. The final diagnosis is as follows: Some simple fault perhaps a connector or a crimp termination caused the first occurrence. I then compounded the problem by replacing my buried RG58 with an unburied and, I now see, a more parallel routed feeder which locked the problem in via antenna coupled common-mode currents. This also explains the fact that I could keep operating provided I kept power below 40W. Some respondents felt there was a KAT problem which compounded the problem, I always felt that the problem lay outside the shack but that maybe, just maybe, the KAT might be a bit sensitive to the problem. The only thing I would ask the Elecraft design team to investigate is whether the SWR circuitry has to respond to the common mode currents as it does. Probably not a firmware issue though! Thanks to the many people who made so many helpful suggestions. E Pluribus Unum! Ray Coles, C.Eng.

Re: [Elecraft] K3 - No speaker output
The final addition to the AF amp protection circuitry was phased into production about a year ago. I'm trying to determine what the first S/N was. We'll also be making this available as a mod kit shortly. There have been a few other improvements to the AF amp circuitry, all phased into production a long time ago. These are listed on the K3 mods page. The K3 owner who posted about not having speaker output has a very old K3 (~S/N 300) which had none of the upgrades.

Re: [Elecraft] K3/KPA500/KAT500 SWR Problem WHITE SMOKE!
Good news Ray, I swear by Ian's choke design. It has worked miracles here. As I mentioned in an earlier post I went straight to the 3 section GM3SEK choke, in fact two of them, one at each end of the coax section. Works a treat. I can't speak highly enough of the KPA500/KAT500 combination. 73 Stephen G4SJP On 15 January 2014 15:59, Ray Coles raycole...@gmail.com wrote: I am pleased to relate that I seem to have finally nailed this problem, and I think many of those who gave me helpful advice and the Elecraft design team will be interested in learning what the final diagnosis and cure turned out to be. A quick recap: About 2 months ago, operating at about 75W into my trusty OCFD, the KAT500, KPA500 and K3 SWR readings shot up into the red and all DX fun ended abruptly. The problem remained, so I started looking for the culprit: I pruned tree branches that were touching the antenna after a recent storm. No joy. I replaced my 300W 4:1 balun at the end of my RG58 buried coax feeder with a 1KW unit. No Joy. I replaced the buried RG58 feeder with UR8 which took a new route, avoiding burial. No Joy. I dropped the antenna and replaced the 300ohm twin feeder from the balun to the T piece, the T piece itself and the antenna wire and dog bones. No joy. At this point I consulted the Reflector Oracle, and the most common response was common mode current on the feeder caused by OCFD unbalance. I did research and decided to build the renowned GM3SEK choke balun. I chose the mid range version which covers broadly 5-14MHz and installed it just south of my 4:1 balun at the North end of the feeder. No Joy. Further ideas from reflector pundits suggested that it might still be common mode, but coupled from the antenna into the feeder where my GM3SEK choke wouldn't help. Fortunately I had bought enough Fair Rite oval cores to build all three (Lo/Mid/Hi) balun designs, so in a final roll of the dice I built the two core Hi Band balun and installed it in the Shack next to my rig. The hi band version has a fairly flat impedance curve and reaches down to 7MHz and up to 30MHz. IT WORKED! I have run 100W on all the bands from 40m to 10m and I have seen no run away SWR readings. My 25W tune value stays rock solid. As a final push-my luck step I turned the KPA500 to operate and ran 400W SSB. No Sweat! All of these things were no-nos yesterday. The final diagnosis is as follows: Some simple fault perhaps a connector or a crimp termination caused the first occurrence. I then compounded the problem by replacing my buried RG58 with an unburied and, I now see, a more parallel routed feeder which locked the problem in via antenna coupled common-mode currents. This also explains the fact that I could keep operating provided I kept power below 40W. Some respondents felt there was a KAT problem which compounded the problem, I always felt that the problem lay outside the shack but that maybe, just maybe, the KAT might be a bit sensitive to the problem. The only thing I would ask the Elecraft design team to investigate is whether the SWR circuitry has to respond to the common mode currents as it does. Probably not a firmware issue though!

The K2 heat sink was cold to the touch, by-the-way. WTF!?? Powered off K2, turned back on and same error message. Next time, power K2 and 12vdc supply. Powered back on DC supply, then K2 and got same PA HOT message….now it’s getting scary! WTF…….I pull off all cabling and run K2 into dummyload. Power back up and PA HOT error again! Now I’m considering a hardware reset which I really don’t want to do. So…….for grins and gigglys this time I turned K2 off, DC power supply off and removed the 12vdc cable from back of K2 and voila, when I reconnected DC power, K2 operating normal again and back on air making 100w thru KAT100 into dummyload and into dipole. So, for my K2 wizard friends, any thoughts what happened? I’m thinking a relay got “suck” in some weird state and took all this to get everything reset again?

Hi Ed, This has happened to me. I heat my house with a wood stove and the radio shack is far away from it. When the door is closed it can get quite cold in there. As Wayne explained to me when my fan started up on one frosty morning it is because he is from California and knows little about weather below 0 degrees Centigrade :) The firmware for starting the fan depends on the temperature reading.

Re: [Elecraft] KX3+KXPA100 operation improved when running from a 12-V battery
Hi to the group. I hope the group wasn't thinking my test conditions were my recommendations for running the KX3-KXPA100 station. I purposely set it up under marginal conditions to test the new software and originally to test the old software. The battery is over 4 years old and I may replace it this spring. There were 3 fuses in the circuit and the KX3 was getting it's power from the duel socket on the KXPA100. The old battery was several tenths of a volt lower than my newer battery although it definitely does not have a dead cell. I could solve much of the problem with the original software just by running the KX3 directly off the battery. A new battery would also help. My goal when camping is 6 db over 5 watts which is 20 watts or 10 db over 5 watts which is 50 watts. I ran at 100 watts on my dummy load to make the entire test as tough as possible. I run almost 100% CW when I am camping as even low power RTTY or PSK31 draws much more total currant from the battery then CW in an hour of operating. Fargo has two 50 KW broadcast stations in the area so I was not surprised when I tuned in a 5 KW station that was 230 miles from me that I had the interference problem with the 160 position. I was pleased that the NOR position still worked but having said that I can see myself using the 160 position when I camp in the north wood of Minnesota. Once again I appreciate these two new options and they are meant to be used with reasonable care. 73 Ken W0CZ w...@i29.net Sent from my iPad On Jan 14, 2014, at 9:36 PM, Wayne Burdick n...@elecraft.com wrote: Thanks for the report, Ken. At lower voltages, especially in voice modes, you should consider dialing back power output to preserve the amplifier's headroom. For example, if the supply is dipping below 11 V, I back the power down to about 50 W, just to be safe. This is only a 3-dB drop in power but it'll be a little easier on the gear. For higher/lower voltages, adjust accordingly. Of course the amp and radio will protect themselves if, due to reduced voltage, you exceed a threshold of current drain, temperature, or other parameters. 73, Wayne N6KR On Jan 14, 2014, at 6:11 PM, Kenneth A Christiansen w...@i29.net wrote: I brought up my old deep discharge battery and am extremely please with the way it now works with the KX3 and the KXPA100.

Eddy, If you turned it on when its temperature was below 0 degF, that can happen. The programmer's bug-a-boo of a maximum number of 255 and a minimum of 000 has bitten you. When the numbers decrease to below 000, the next lower number is 255 - which indicates a really hot K2! Even if it is not true. It is not really a big problem and can be solved easily in the menu. Let it acclimate to the ambient temperature (an hour or so powered off) - and measure that temperature in degC. Then enter the K2 menu for TPA and edit the parameter. Set the parameter to match the temperature in degC and exit the menu Job done.

[Elecraft] K3/KPA500/KAT500 + ocf dipole
I happen to think that the K line and the off-centre-fed dipole make for an ideal compact station, particularly for those with very restricted land on which to put just one aerial. As you have concluded, common mode current must be conquered and I think the GM3SEK chokes are ideal where weight is not a factor, eg on the ground and in the shack. I built one in a weather-proof box with the LF version and the HF version all in together for a very neat solution. Your problems were mainly with transmit, but these chokes also work on receive keeping noise off the coax which would otherwise creep right inside the radio. As others have said, you need a choke at the feed point after the balun and others down the line depending on your layout. A feeder that does not drop vertically from the aerial induces further cmc onto the coax. Another good and easy thing to do is ground the coax shield before it enters the house, but not everyone can do that, so a choke at the radio does the job. DJ0IP/NJ0IP is putting data on his website from a very large number of measurements on various combinations of ocf dipoles to show which chokes and baluns work best. His project is not yet finished but it is the most comprehensive set of measurements I have seen on practical aerials. David G3UNA ...the most common response was common mode current on the feeder caused by OCFD unbalance. I did research and decided to build the renowned GM3SEK choke balun.

Re: [Elecraft] How do I generate a Key Down to tune an external 6m amp?
The easy way is to hold the dash on the bug. If you want to use a straight key just wire it across the terminals on the bug. You don't need but one key input. The way the old telegraphers used a bug was to insert the flat connector between the base and the copper/brass strip that connects to the contact on the straight key and the straight key was permanently bolted to the desk and wired to the telegraph line.

Just what I can make in dots or dashes Is there a way to get key-down WITH a closed PTT so external 6m PA comes on? -- Bob KD7YZ http://www.qrz.com/db/KD7YZ www.denstarfarm.us/LGD __ 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 __ 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
[Elecraft] KXPA100 Assembly Manual Suggestion
I assembled KXPA100 #333 this evening and have 2 assembly manual suggestions. 1. Figure 4 on Page 6 and Figure 10 on Page 11 show the tabs for attaching the cable shield oriented in the 12 o'clock position. I assembled them that way and found the Ant1 and Ant2 coax to be stressed at the connector when attaching the end panel. I rotated the tabs 90deg counter clockwise so they're facing the 9 o'clock position and and found it much easier on the coax. I also gave each tab a 45deg bend for less pull on the coax. 2. Figure 6 on Page 8. The warning just above the picture says Place one lock washer between each standoff and the LPF board. Figure 19 on Page 16 has a warning that says If you failed to install two lock washers under each standoff as shown in Figure 6 on Page 8 I only put one washer and mine seemed to fit okay. But they're conflicting warnings. Awesome kit which assembled in roughly an hour. Looking forward to using it! 73, Tighe -- Tighe Kuykendall NK4I | www.NK4I.com | Follow Me on Twitter: @NK4I ARRL Life Member, NAQCC #6467 __ 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
