Re: [Elecraft] Are you satisfied with your K3?
And to elaborate on this theme, it is my setup on QTH up for trade. It is equal in price with a new FTDX-5000MP, and I am asking for the value of a used MP for it. Separately, I have tried to sell it for what used MPs are going for. I had tried to sell it for that price previously on QTH, and got a lot of flack about the price being too high. Do the math. Unfortunately, some gear retains resale value better than others. I traded a FTDX-9000MP for the K3, P3, KPA-500, power supply, Heil Mic, Mic stand and a Swan 700CX. I based the trade on the published receive specs. I had K3 fever, and was pushing for the best possible receive specs and capabilities. The KPA-500 would offer me 100 watts extra power, and the Pan Adaptor, while showing potential for further development, fell a little short in comparison with the DMU capabilities. The 9000MP was used nearly exclusively for government spectrum in volunteer contingency communications support. Had I asked the correct questions, I would have known before hand that the MARS/CAP software band limits removal routine cut out a fair slice of spectral real estate between 7650 KHz and 10 MHz. Also, 100 percent of my operation on federal spectrum was in nets authorized for mixed mode operations; where digital and voice communications were allowed, and it was expected that the operators were capable of operating either mode on command, and both modes within minutes (or less) of each other. Where the K3 excels in CW and Ham Band Dx, it doesn't match up with the operability of an IC-718 in my application. My mistake; no one else's - I just never thought it possible for the limitations to be present in a rig of that cost and reputation. On top of that, the fellow I traded with claimed it to be perfect in every way, and I had to replace a FET in the low power amplifier to get the power stability and distorted transmit audio problem corrected. The amp went back to Elecraft, after it developed a high reflected power error, even into a dummy load. We live and learn. I had tried to use it with an IC-756 Pro II, and a LDG AT-1000 pro. The results of that combo was a fused antenna relay in the 756 pro and all the magic smoke was driven from the AT-1000 Pro. Fortunately, I was able to isolate the problem in the Icom and replace the relay. LDG made the tuner good, with an updated model; sent to me at no cost. We all need to be careful in our trades with fellow hams.. I hate to admit that.. Where the features and operability of the K3 may have been a bit less than I was expecting, the Elecraft Customer Service was a far more pleasant experience. Howard was able to point out the exact failed component over the phone after a few trouble shooting procedures. He was patient, informative, and well versed on the product. When the replacement FET that I ordered from Elecraft arrived, and was replaced, a phone call netted more patient responses from Howard as I set the Bias on all three of the FETs on the LPA Board. When I sent the KPA-500 in for repair, the turn around was extremely quick, and the cost was certainly fair for the work done,. No complaints at all about how Elecraft supports their product. All in all, I wish I hadn't ever let the FTDX-9000MP go, and wish I could recover enough to get a FTDX-9000D and only lose 200 watts over the deal. I am still hopeful I could possibly recover enough to get a used FTDX-5000MP, (lose 3 micro tune modules, true second receiver, the DMU, TFT screen, and 200 Watts). If no hope of either of those possibilities, I will know that I at least tried to recover the value of a used setup when compared with a used setup of another manufacture, where both carried the same retail price and age. But, FWIW, it is all on me. No one forced me to keep trying to build the best station for my type of operations. I have done some reconsidering, and will be moving away somewhat from the contingency communications volunteer operations, and devote some time to other endeavors. It is one of those situations where you really wanted to do the best possible job that your equipment would allow, and just got too close to the abyss. I could have done worse, I suppose. There is still a lot that can be done with the setup in the environment that it was ultimately designed for. The shortcomings were in my expectations, not the equipment. I maintain a presence here, as the firmware is evolving, and I have already seen improvement in the capabilities after less than 2 months of ownership; by firmware evolution alone. I only threw away the bath water; I kept the baby.

Re: [Elecraft] K-Line system integration questions
FWIW, you can find InsideOut Edgeport interfaces on eBay that are usually quite reasonable. I have them in 2 port, 4 port and 8 port configurations.

Each port can be configured, port number renamed, etc via the Control panel - System... The USB ports have a tendency to wander around if you use them in real world situations.

Re: [Elecraft] K3 Problems
Chas, If a single button held in on power up won't cure it, grab a handful. The CPU should still be attempting to strobe the panel for key presses. All you want it to do is have the lockup clear up long enough for the cpu to sense a correctable failure. If/When you get it unlocked; immediately reload all firmware; or at a minimum, the firmware that seemed to be affected. And the word corrupted is probably the most salient term here. You may have to scare the cpu worse than it already is, before it will allow a fix. You may be amazed to find that if you disconnect all devices, cables, etc and physically move the K3 so you can be sure it is not connected, in any way, to the real world; the problem may dissipate after a few hours; provided it is the equivalent of a ground loop. If not, removing the back-up battery and letting it stand for a half hour may bear favorable results. This is a computer. It fails just like any other computer.. It's stability is largely dependent on the complexity of the firmware's ability to be able to second guess every way a task can be attempted. Before you try the radical approach; Elecraft Support should be available soon, as they sun is coming up on the left coast.

Re: [Elecraft] Small HF amp suggestions
Take a look at this site: http://www.n2ckh.com/fl110.htm These show up from time to time. My little QRP circle of friends have found 2 in the last month. Both were around $300. When you see a solid state amp that was built in the late 70's with the original output transistors, you get the feeling it was put together correctly. The amp can actually take up to 15 watts in, and can develop higher output than the 110 watt advertised output. I believe it has a 200 watt PA potential. The Tokyo HL50 (forerunner to the HL45) can be purchased in the 350 - 400 price range. If you have to order one new, and pay shipping, it can become cost prohibitive. You can always go the Metron route, and have up to 1K watts; if you have enough battery and charging system.

[Elecraft] K3 Receive Sensitivity Consistency
When I turned the K3 on this morning, I decided to listen to 60m, to get away from the contesting. As I went through the bands from the 2 meg frequency I had been monitoring, when it got to the 5 MHz band it seemed to be a bit deaf. Volume was considerably lower, but signal on the P3 looked consistent with the other bands. Going into the Menu and bringing the Receive EQ to +16 on all 8 frequencies did not restore the volume level. Using the Band switch, toggling back down to 75m brought similar results; lower receive level. However when going back to the original 2 Meg frequency and manually tuning up with the VFO, the sensitivity and volume remained consistent all the way up to the 5 Meg freq that I was trying to monitor initially. After that, going through the spectrum using the Band Select switch yielded consistent results. When using the VFO, I was looking for a magic relay click, or some crossed frequency threshold that triggered a return to sensitivity, but there was no degradation as long as I was going up the band with the VFO. Serial Number 5063; Anyone else seen this before?

Re: [Elecraft] K3 Receive Sensitivity Consistency
Preamp, Attenuator, ATU, AGC were all checked before determining that the audio on 60m was lacking. The levels on the P3 were also checked to aid in determining the problem. RX EQ was all maxed out in able to overcome the inherit audio attenuation when the EQ settings are moved off of +16. My guess is that it seems to be firmware related, and for now, the problem has been cleared out of the processors scratch pad memory, and may not show up again.

Re: [Elecraft] KPA500 input SWR in standby ...a question.
FWIW, below are my notes - from before I sent mine in for repair. Something happened that caused an LDG AT-1000Pro to toast the protection Diode, and an Icom IC-756 Pro 2 to burn one of the contacts off of the antenna 1 / antenna 2 change over relay. I had already taken the K3 out of line for unstable output before trying the Pro II. We found one of the drivers bad on the K3. It is looking like the amp is common to all items that were affected. I am in luck in that I can replace the driver on the K3, and the relay on the Pro 2. Dwayne at LDG will treat me right on the 1000Pro, so all I am really stuck with so far is the $65.00 to ship and insure the LPA500 to Elecraft, and whatever they find wrong, plus return shipping and insurance. Here is what I wrote: MFJ Analyzer shows (worse case at 50 MHz) 1.5:1 in standby and 1.1:1 in operate with dummy load connected directly to amp output. My problem is that the amp shows high SWR and REFL HI error whenever it is keyed; no matter what the power or load or band. I am guessing whatever went wrong with the amp sent a fair size spike out to both the rig and external tuner. If you are going to die, you may as well take a few with you :) I will find out soon enough.

Hi All, Thanks for the messages about the power up LCD blink - it's the way it should be. Now another question: my KPA500 replaces an old AL811. I noticed, when I connected the KPA500 in line, that the K3 SWR meter was giving slightly higher than expected readings with the amp in standby. Given that nothing else in my transmission chain had changed, other than swapping over the amps, I thought this was strange. I also noted that my LP100 meter would show an SWR of 1.0:1 (on the rig side of my manual tuner) while the K3 meter would show an SWR of 1.2:1. The KPA500 SWR meter agrees with the LP100. Looking at this, I put a dummy load on the output of the KPA500 and with the amp in standby, I found that on 20m and above, the KPA500 input SWR is around 1.2:1 with a maximum of 1.3:1 on 6m, measured by an Antenna analyzer on amp's input. Also, taking the amp out of line by physically disconnecting it and using a coax barrel connector to join the input and output lines causes the K3 and LP100 meters to agree. So, is this input SWR variation in standby mode, within spec for the KPA500? I didn't see this with my AL811 in line, but then I'd carefully adjusted its tuned inputs. Please tell me I'm fly specing here and to stop obsessing :) Cheers JohnVK7JB __ 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] K3 Data Modes using SignaLink USB
Got my cable in today to do soundcard data modes on the K3 with a SignaLink USB Not much chance of getting the cabling incorrect, installation was uber easy. I used the rear panel inputs and outputs for the additional isolation; allowing me to keep the Mic on the front panel for mixed mode operation requirements. However, I am not having much luck finding a stable plateau to chance moving it off the dummy load and on the air. Output power isn't stable, and rises while the rig is in transmit. If power is changed while in transmit, it drops off, then starts building again. No power is generated until output level on the interface is high enough to generate ALC action. Not much chance of anything dependable here Where am I going wrong? I never run any ALC, unless it is an occasional flicker; usually a reference to decrease volume for a purer signal. Some prefer to run the output power to 25 watts and run 50% ALC, and share the signal up and down the band. I would prefer to set the power to a higher starting point, set the volume level correctly, then decrease the power, if necessary, maintaining a clean signal throughout. Anytime the power level on the K3 is changed at all, the output falls down and starts to build again. Around 30 to 45 seconds into a transmission, it may stabilize. I have used the SignaLink USB on a FT-897, FT-817, FTDX-9000MP, TS-2000, IC-756Pro II, IC-7000, IC-706, IC-7200, FT-857, FT-2000, Jupiter, IC-756 Pro, TS-870, TS-480 And never experienced any instability of output before.

Re: [Elecraft] K3 Data Modes using SignaLink USB
Don, Thanks for the info. I will give it a try, and will find out soon enough if the 4 bars of ALC activity is trashing the signal quality, as anticipated. From the other brands I have used and am currently using, the K3 seems to be the only one that uses this approach, so I am not sure if I understand your reference to internet wisdom... Does the K3 use some other kind of output processing, and just hang an ALC label on it? No problem on driving the SignaLink; I can match them to the other gear, using jumpers or resistors, as well as matching in the software input config. Please don't tell me this is the same approach that Microsoft uses when contemplating changing a light bulb; defining darkness as the new standard :) David KD4NUE -Original Message- From: Don Wilhelm [mailto:w3...@embarqmail.com] Sent: Friday, October 12, 2012 10:46 PM To: dalit...@bellsouth.net Cc: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Data Modes using SignaLink USB David, Are you following the instructions in the K3 manual, or are you trying to follow the wisdom supplied on the internet? The K3 is different than the internet wisdom transceivers. The fact that you say the output is not stable leads me to believe you are trying to use the internet wisdom that tells you to set the power to maximum and use the audio injection to control the power output. That is a recipe for problems when using the K3 (K2 as well, but that is not the question). Refer to the K3 manual and adjust the audio drive to give 4 bars on the ALC meter solid and the 5th bar flickering - you can do that in TX TEST so you do not bother your ham neighbors. Once you have done that, set the power knob to your desired power level and all will be well. The SignaLink may have to be set for Line Level output - it is plugged for mic level by default. See the manufacturer's documentation to see how to set it to line level output. 73, Don W3FPR On 10/12/2012 10:19 PM, David Little wrote: Got my cable in today to do soundcard data modes on the K3 with a SignaLink USB Not much chance of getting the cabling incorrect, installation was uber easy.

Re: [Elecraft] K3 Data Modes using SignaLink USB
Don, That puts things into a better perspective. With that in mind, it does mimic normal ALC operation. I don't quite know how to interpret the instability in output while it is measuring volume units, before it switches to ALC and stabilizes. -Original Message- From: Don Wilhelm [mailto:w3...@embarqmail.com] Sent: Friday, October 12, 2012 11:01 PM To: dalit...@bellsouth.net Cc: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Data Modes using SignaLink USB David. I would like to point out that the K3 ALC indicator is also a level indicator. The onset of ALC begins at the 5ht bar, and bars 1 through 4 do not indicate any ALC action at all. They are more like a VU meter provided to allow you some metering to help you adjust the audio level. 73, Don W3FPR On 10/12/2012 10:19 PM, David Little wrote: Got my cable in today to do soundcard data modes on the K3 with a SignaLink USB Not much chance of getting the cabling incorrect, installation was uber easy.

You can reduce it if you go into the menu and set AGC*THR to 5 (or 4). 4 will totally eliminate the distortion but will reduce the maximum volume the radio will produce. For me, (I'm going to say it) the wimpy audio amplifier is a big disappointment. As you have discovered, even using an external speaker it does not produce decent volume. If I use the radio outside in my patio, headphones are pretty much manditory. Even with headphones, if my neighbor is mowing his lawn. it can be difficult to hear. My K2 has enough amplifier that I can just drown out such noise. I would certainly have accepted a few more mA of current drain for a decent audio amplifier. 73/72 de Al, W2GZN From: Johnny Siu vr2...@yahoo.com.hk To: k...@yahoogroups.com k...@yahoogroups.com Cc: Elecraft elecraft@mailman.qth.net Sent: Tuesday, October 2, 2012 3:53 AM Subject: [Elecraft] KX3 - audio distortion after level 30 Hello elecrafters, I fully understand that audio from the internal speaker of KX3 could be distorted at high level say 30.

[Elecraft] 43 ft Vertical Balun
Those of you who a thinking about a 43 ft vertical or how to feed it might read the links I have provided you here. I have built a 43 ft vertical from a 50 ft telescoping Rohn push-up pole. I am using a mesh ground system under it thanks to Home Depot's 4ft x 7 ft mesh sheets linked together, radial wires, grounding rods, and a homebrew balun. I am using a K2 with ATU and 100 watts through a short run of LMR400 coax to the base of the antenna where the balun is located. The 43 ft vertical also supports my windom. The windom is insulated from the vertical. Below are several links on the 43 ft antenna including the AD5X info on how to build your own balun. I based my balun on his and it works fine. If you do not wish the build your own balun, a great one can be purchased from Balun Desins LLC. They offer two models for low and high power.
