[Elecraft] PA No worky...
Ok well I'll provide a bit more information. I've pulled the PA and taken a look at things and nothing looks like its gotten hot at all. Nothing is obviously wrong at all. I've checked all my filter settings (which hadn't changed since it was working a few minutes ago) and they all still seem to be correct. I reloaded the firmware to the radio and also restored my previous configuration. I've redone the synthesizer configuration because I've recently added the synth stiffeners. I then redid the TXG calibration. 5 Watt TXG calibration goes 100% successfully. However 100W TXG Calibration results in an ERR TXG message. It seems like its doing everything that it should to make the radio produce 100 watts but the PA just isn't doing its job. Flipping between PAio ON and PAio TST does produce a relay click so the PAIO is doing its job. I should also mention that all fan speed tests check out ok as well. If I'm forgetting anything else to check please enlighten me.

[Elecraft] YET ANOTHER (VERY) HELPFUL FIELD DAY FEATURE
Folks: In order to prevent 'knob twiddling' by unfamiliar ops who like to 'twiddle' knobs of your rig, especially in order to get an INDICATED 100W OUTPUT IN SSB MODE ON AN EXTERNAL (AVERAGING) POWER METER... The K3 offers a feature to LOCK the MIC GAIN, COMPRESSION, and POWER OUTPUT controls so an uninitiated user can't 'crank up the gain' to be 'louder' (and much more distorted) on the other end... Go to CONFIG | PWR SET and press [1] to lock/UNlock MIC GAIN, COMPRESSION and POWER level controls once they've been 'CORRECTLY' set by the owner! Works just GREAT! We used it last year and it SAVED us from several 'poor audio' reports. 73, Tom N0SS __ 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

Sure. > What are your thoughts. My last question please. What’s “73” and I thought > “Q” was aerodynamic pressure as in MaxQ ? "73" is a friendly "word" between operators. It is generally translated "best regards." Q does stand for aerodynamic pressure (where it is usually lower case "q"). In electronic parlance, Q (generally upper case) indicates the quality factor, generally for an inductor or capacitor, and is the ratio of the reactance to the resistance of the device. Q can also be used as an abbreviation for QSO. In the early, early days of radio telegraphy, a number of procedural signals were defined starting with the letter Q. These were three letter combinations that could be used to help communicate radio concepts -- possibly between operators who had no common language between them. These Q-signals were adopted by radio amateurs, and have become synonyms with certain radio concepts. A QSO is a contact between stations. As you work to get your license, you'll learn about 73, Q and other things as well.

Re: [Elecraft] Low headphone audio level
Hi Pete, I have the same problem with the Heil Proset that I purchased from Elecraft. I also have a Sennheiser HD280 Pro which has a higher output but is not as comfortable as the Proset. I personally think the headphone AF output should be higher. (Yes I have the config on HI). Admittedly my hearing is not as good as it used to be. If you want to see how it could sound enter this code several times in the K3 Utility under the Command Tester tab. !66; Each time you enter it the headphone level will increase slightly. But this change is not remembered through a power cycle. I've asked for this to become a config choice on this reflector and in direct e-mails to Lyle and Wayne. (Wayne as recently as 5/18 but no response). I guess I'm the only one requesting it. To solve the problem I plug the headphones into the rear speaker jack. It solves the problem but if I want to use the internal speaker I have to pull the plug out. If you do this be sure to set CONFIG:SPKRS to 2 for stereo. 73, Mike K2MK Pete Smith N4ZR wrote: > > I have just gotten around to trying headphones with my new K3, and am > surprised by how much audio gain is required for an adequate listening > level with my old Heil BN-10 (?) headset.

Re: [Elecraft] Low headphone audio level
You might consider plugging a stereo switchbox into the rear speaker jack and plugging the speaker(s) and the headphones into the switchbox. I prefer that because it's easier and involves no wear on the radio's jacks. I use an old Radio Shack "Stereo Source Audio Selector (#42-2112). That one has three outputs so I use stereo computer speakers, a Heil Proset Plus, and a Sennheiser HD-280, which is my favorite.

Funny, the rules say: 7.2.4. If any or all contacts are made using an output power greater than 150 Watts, the power multiplier is 1 (one). That suggests that 1KW is perfectly legal.

Hi Don, Thanks for the info, I downloaded the program and carried out the calibration procedure, and yes, it was interesting to watch but didn't cure the problem. Here's the results I get, the power indicated is taken from the KW.

Re: [Elecraft] Low headphone audio level
Hi Mike, We sort of got sidetracked from the original posters remarks. It's about low headphone level on the K3. If the level were a bit higher there would be no need to plug the headphones into the speaker jack. Similarly each pair of headphones you grab seems to have a different level. I have 3 different headphones and don't intend to buy a forth. Naturally the one that is the most comfortable is also the one with the lowest level. And I understand that most people don't seem to have this problem. It might be better hearing or better headphones. One of my earlier rigs (maybe my FT1000D) had a headphone equalization adjustment that permitted one to adjust the headphone level so that it was not necessary to readjust the volume control when going from speakers to headphones and vice versa. That would be a nice feature on the K3 and would be most effective if it were handled as a CONFIG adjustment. 73, Mike K2MK Mike-14 wrote: > > I have the Yamaha CM5000 headset plugged into the rear panel, and toggle > the external speakers with a macro. > > 73, Mike NF4L > > Mike K2MK wrote: >> Hi Pete, >> >> I have the same problem with the Heil Proset that I purchased from >> Elecraft. >> I also have a Sennheiser HD280 Pro which has a higher output but is not >> as >> comfortable as the Proset. >> >> I personally think the headphone AF output should be higher.

Re: [Elecraft] Bad start to FD - smoked a K3!!!!
Jim - ( rant mode on ) What you say is perhaps pertinent to all you flat-landers - but then there's those of us who have to run high power just to be heard. Or, we could equalize things another way. We can run 100 watts, but then we would insist that all of you South-48 types not count any QSO from a station closer than 1500 miles from your FD site. That's what FD means to us, you see. Other than within Alaska, the closest FD stations we can work (Seattle, WA area) are 1500 miles (or more) distant. If we don't run the amps, our QSO rate is about 1/5 of of what we get at higher power. Part of the problem is that all the flat-landers are aimed East or West, not north or south. And 150 watts to 40 or 80 meter dipole that is 30 feet high doesn't make it up this way very well - particularly when we have daylight 18 hours of the day (solar time, which means disregarding civil offsets like daylight saving time, means the sun comes up about 2:00 AM and sets about 10:00 PM.) I have long maintained that FD stations located in areas not part of the contiguous 48 states should be allowed to run higher power without penalty. There are FD stations from Guam, Hawaii, Puerto Rico (and so on) too. Hawaii is more like 2500 miles to it's closest FD neighbor. ( rant mode off.

Bill, I'm sure this will generate a flurry of responses without asking important questions. :-) How far apart were the antennas, and how well were the antennas constructed and installed? The how far apart thing is easy. The more complicated and important thing is the installation. If they didn't suppress common mode from the antennas, you could have direct RF excitation coming through wiring to a common generator. If the antennas were next to each other, then you could have direct coupling. Even feedline lengths, because it affects current and voltage on bands where the feedline is mismatched, can have a huge impact. Also, some antennas respond much better to out-of-band signals than other antennas do. To give you an example of how immune the K3 is to problems, I have several antennas within 1/2 wave of each other and have no issues at all with the K3 on one and 1500 watts on the other antennas. But...these are planned antennas that have reasonable band-selectivity. I don't do anything foolish. At field day, I have never operated without a bandpass filter on my rigs. As a matter of fact I keep two or three old Johnson KW matchboxes around for just such occasions. I made some measurements in my K3 and antennas because I had an unexplained failure in the post mixer amplifier. (This had NOTHING to do with RF levels, it was a new operation failure when I first connected the K3 by itself.) Current can get pretty high in that device when input level goes over 10-20 dBm. The mixer is tough and just passes the input signal right through! I'm not sure what the most common failure is, but when I looked at mine the device following the mixer seemed to be the thing that got hottest fastest. Of course with a very high quick spike, damage could be almost anything near the front end. Bottom line is if an extra 10 dB from an amp caused the K3 to fail, the system was not planned very well. You should have a hell of a lot more headroom than 10 dB below catastrophic failure in a good installation, so it might have ate the K3 up anyway over time at 100 watts! 73 Tom __ 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] Bad start to FD - smoked a K3!!!!
Ok guys lets get a few things straightened out here. Number one all of the answers that were slanderous or laced with ridacule were very much uncalled for. This was not a planned operation. It was the case of one operator rising early on FD and getting on with power. This was not and I repeat not going to be used in field day operations. The operator of the K3 that was fried arose and went into an operating area completely away from the gentleman whom was operating qro and turned on his K3 unaware of the early morning dx hunter whom was just being a ham radio operator. We posted the incident hoping that someone would come up with a cure that we could apply in the field. That was all that was intended and nothing else. All here are experienced operators and would never have intentionally done this on purpose. It just is a very unfortunate incident that yes should have not happened but it did so now we will try to get it fixed and go on. We are sorry to have cause so much trouble. I suggest this thread should end unless someone can give us a credible fix.

Hi Bill You probably smoked the KANT board. The 8mhz trap seems to get smoked by nearby high power transmitters. This happened to 2 of our clubs K3's in a field day operation.

Re: [Elecraft] Bad start to FD - smoked a K3!!!!
The KANT3 board is easy to work on. You need to be careful about not bending the voltage regulator leads as they will fatigue and break if bent repeatedly, but otherwise, working on it is very straight forward. In the case of my problem, the 8 MHz trap was suspected to be the source of a problem causing low output on 30 meters but wasn't.

Re: [Elecraft] Amps at FD ?
Maybe, but I have been in emergency comm situations where high power on 80m was required. When a hurricane has wiped out local commas and you can only do it with high power, then that is what you use. It is important to practice for that situation.

[Elecraft] K2 Receiver issues
Greetings, I just finished building my K2 and seems to work pretty well except that it does not received like I think it should. I put it side by side with my K1 and the K1 picked up signals better. They were louder and clearer on the K1 than the K2. I have made about 3 passes through the alignments and am comfortable with those. The S meter, when I am listening to a strong signal, will barely come off the first bar. All of the resistance and voltage checks along the build have come out fine. I am now deciding how to attack this issue and would appreciate any suggestions anyone has. I am going to be doing some of the voltage checks from the back of the manual next week and also seeing if I can find a 10 MHz crystal to make the signal generator to begin that process.
