What I bring up below may have been discussed before. I'm not much of a network person, but I believe UDP packets are tossed out with no error correction at all (like unproto X25 packet). Having lived in a packet loss environment for a long time (years) and running IRLP, I can tell you that when a packet it lost, it is lost. The command, audio, whatever, will be lost and have to be repeated in order to get it through. As I said, this may have been discussed before and I'm sorry for any repetition it brings. It also causes pretty bad holes in the audio if it is sent UDP.

Re: [Elecraft] KPA-500 fan noise
On Mon, 2 Jun 2014 06:05:22 -0700 (PDT), Harry Yingst via Elecraft wrote: > You could always try replacing the fan with a quieter fan. I would consider that myself, but only with one recommended by the good people at Elecraft. The fan in the KPA is VERY loud when it hits the last two speeds. Warp and Turbo Warp would wake my wife in the next room if she was a light sleeper, although I virtually never get it up that warm. It was just my short excursion on 6M FM that really got it up there fast. My issue isn't with the fan operation, although I wish it would come on just a bit earlier than it does. My issue is with the sound level out of this particular fan. It's a screaming banshee when it gets up there at speed. It's a very "raw" sound, not the sound of air moving, but of a high speed motor. My only hesitation with putting a different fan in it would be compatibility with the speed control circuitry. I just won't do it, especially under warranty, without Elecraft's recommendation and blessing. They've got a good product and I want to keep it that way. Typing this up raised my curiosity and I went to the shack and ran a control test into my Bird load. I set my rig at 10W on 52.525 FM, which gives me 200W output. With manual fan control, I made sure the amp was cooled to 33C as a starting point, and then set the fan back to NORmal setting. I keyed the rig on FM at the (unmeasured) 10W setting, and sat back to see what it did. It took 75 seconds to reach 70C. At which point, the fan is at 5, a rather noisy speed. It seemed to level out at 77-78C for a bit and then went to 80C at 4:50 minutes. I ended the test at that point. At 80, the fan went to 6, the highest speed, screaming away. With this test, I'm confident that it would probably handle anything I would ever do to it in normal operation, especially given the fact that I'm not dumb enough to do that test at 500W output. :o) I think the fan does a pretty good job, but do wish it was quieter. I never hit those higher speeds, except in test conditions like this. My normal use has it hitting 70C only on the rarest of occasions.

Re: [Elecraft] KPA-500 fan noise
> Am I missing > something here or is this normal? Sounds normal for mine. I've recently had mine on 52.525 in an FM QSO. I ended up at about 250W with short transmissions. That didn't surprise me much at all, because my KPA seems to produce quite a bit of heat on six meters anyway. Hit the dummy load and do some continuous carrier testing and see how long it takes to hit high speed. It won't take long. That's one screaming fan. By the way, you can sample those speeds just by going to the menu and changing the fan control setting. That menu item sets the minimum speed the fan will run (auto = off when below threshold). One thing you might try is to set the fan to the first or second speed (not auto) when you're operating those modes. That let's the fan run all the time at the speed you set, which allows it to cool in receive mode when it might normally kick down to the off mode until you key the next time. Don't miss understand, the fan control menu sets the MINIMUM speed the fan runs. It still kicks up faster for warmer operation.

These two statements are conflicting. If you're going to have a StepIR that will go down to 40 meters, you aren't going to want a Ham IV on it. That's way too light, for this country anyway. In fact, a T-Twister isn't enough for that. If you were going to limit it to 30 and above, I might go with a T-Twister, but I really feel my TH7DX tri-bander puts mine through more than it wants. It needs to be rebuilt now and then. StepIRs are heavy too, at least the ones I've seen. But you're right. It's really nice to have the tunable frequency range Did you follow his link? He's got tons of space and can put up wire for anything out to 160M dipoles, with a single support tower or pole. Further, he can go almost any direction with wires without having to weave in and out of tree branches, etc. I sure wouldn't mess with anything like a G5RV or OCF in that situation. The gold standard basic antenna on the lower bands is a simple half wave dipole. He's got room to do that down to 160M. Why go with less? On upper bands, a ground plane does wonders, but a simple 3 element yagi is excellent.

That's not bad, unless it is the weekend for your favorite mode, OR the other mode spills out of its normal area of the band and takes over everything in sight. That happens all the time. And I don't care what you or anyone else says, I know and regularly hear, people just pile into areas of the band where there is other activity, regular nets, etc. Contest organizers should designate a portion of the band where they will accept valid contacts, and disallow the rest.

You're talking to one of the anti crowd. It has nothing to do with speed.

Dumb question time. Why don't you just learn to operate CW the way most people do? CW is supposed to be a manual mode. It is an ART. Copying CW is a part of the tradition of amateur radio. If you have to have perfect CW to be decoded, it's the same as or worse than RTTY. Your brain can decode CW with missing characters and elements quite nicely. Use your head!

You've got a good point, Jim. However, I would prefer a combination of both methods. I'd run a (good low reactance) buss, AND another to the grounding point from each buss attachment point on each unit. Your point about all of the ins and outs on this stuff leaves plenty of room for loops. Also, any time storms approach, I pull the USB ports. They seem to be sensitive to such damage.

You've already had many comments on the subject, and yes, I'm about to add mine. Believe it or not, most of them are true! Ken Kopp has one of the most important ones. Get familiar with DXMaps web site and sign up to receive email alerts when the band opens for North America. As soon as someone puts a spot up for a station, you'll be informed that it is open. You can click on the link provided in the email and it will show you a map of the contacts posted. I pay close attention to that. You'll get lots of "openings" for people on the east coast, or in the southern states, especially southeast. You just have to evaluate what you see to decide if you want to run in and fire up the rig or not. One thing about it, the further south you are, the more openings you'll get. I've been a ham since 1960, and, except for having a 6M FM mobile in the early 70s in Montana, I'd never been on six meters until a couple of years ago. I picked up a used rig that had six on it and a friend about 10 miles from here called me on 2M and told me the band was open. I used my HF beam, a TH-7DX to get on the air and tune around. As it turned out, I was able to work someone! We later had a much better opening and I worked a ton of stations. I was hooked. It's just like ten meters. When it is open, a wet string will work for an antenna. It just isn't open as often as ten. The suggestion that March through August are good months is a good one. My first July on six SSB filled a log book. My second year did a good job on another, even though neither year's travel plans allowed me to work the entire month. I've worked transequatorially to southern Chile, but no JAs yet. My second year on the band, I got a note from an old friend I hadn't talked to in years and he cussed me out for working KL7 before him. He had been on for over 20 yrs and never worked KL or KH. I worked two KLs in less than a week, followed by two KHs. The recommendation to not go too large on the antenna is a good one. Directionality becomes a problem when you are in the monitor mode. You need to be able to hear signals that come in from all directions, just in case. I'm lacking that here, but I do have a good takeoff angle almost 360 degrees. I'm currently running a 5 element so-so antenna at 60 feet. With my KPA500, it talks pretty darned well. You would do well to put up a more omnidirectional antenna for monitoring. > The band is always dead quiet with the small exception of some noise > spikes here and there but very rare. This is pretty normal. However, it does give you a chance to hunt up some noise sources if you have any. Power line noise, and junk like that can really have negative effect on your enjoyment of any band, especially six, where you have to be there and be ready to pounce as soon as you hear something. Openings can last from seconds to hours. > Question: is there any activity for six meters that I should invest > in a nice multi-element 6 meter bean antenna? Start small (3-ele) for now. It is pretty much assumed that we are on the downhill slope of the sunspot cycle and the band will likely be open less and less for awhile. Plus, you are more likely to hear something off the side or back of the antenna when a signal comes in from the wrong direction. > My most dominant operating mode would be CW but maybe some SSB from time to > time. I have no idea what's there as this band has always been blank to me. CW is alive and well on six, but not nearly as much as SSB. Sign up for the emails from Sherlock (DXMaps) and get ready. We just had a short opening to SoCal a couple weeks ago with good strong signals. You never know when it will open.

I have SN 1255 and have heard none of what is being described. I've purposely heated it from cool to in the 70s where the fan kicks into warp speed. At first I was ready to jump in with my "clicking" experience, but it was true clicking, not ticking that others seem to be describing. My clicking experience was rather short lived and I attributed it to a poor RF situation with my six meter antenna. For a short time, I would sometimes get a relay click and rather high VSWR indicated when on six. I replaced a few jumper cables and all was well again, including the output of the KPA. It got even better when I got that Mother's Fine Junque tuner out of the circuit and installed the KAP. It's nice to see just about the same reflected in both units now on the lower bands. Before, I could get the tuner to show zero reflected, but the amp didn't. Sometimes I would slightly off-tune the tuner to get the amp down better. Don't get me wrong. All readings were under 1.5:1.

I know this is not what you asked, however, it may be of interest to you or someone else reading it. IF you are using modern hearing aids, there are now blue-tooth links available for shoving your stereo or TV directly to your hearing aids. I use mine every morning when I get up to link the shack to me while I fix breakfast. It is very useful. The same link can be used for cell phone linking (all without wires), etc. If you happen to be hearing impaired, you may want to look into it. I go through three perpendicular walls to get to the kitchen from the shack, at a distance of about 50 feet. A fourth wall is at a very shallow angle to the path, and also gone through. I can go about 25 feet further than the kitchen, as long as I wear the pendant on the side of my body that faces the shack.

I wish Smith charts had been spoken of and understood back when I got started. To this day, I do not understand them in the least. I wish I did.

You have a very weak point at the point of entry into the PL. A few flexes of the coax, and your shield will be broken and non-existent. Solder through the holes and allow the black sheath to reinforcingly hold the coax in the connector. It should only be trimmed back far enough to clear the holes. I've never been able to use the tinned shield method. Too many stray wires, and/or too large to freely enter the center of the connector without catching. I also don't like the idea of enlarging the holes in the PL, although that seems the least undesirable of the things people have mentioned. If you do, at least make sure there are no burrs on the inside to catch the braid as you thread the coax into the hole. While on the subject, someone mentioned not being able to get the tip of the gun (I use a gun) into the channel where the holes are. Why not? My 300+ watt tip isn't that large. It should fit fine. You do NOT put the tip into the holes themselves. You heat the outer until the folder will freely flow between outer, shield, and (if using one) UG reducer. Make sure solder is FLOWING, not just sitting there stuck on some piece of flux or something. It should flow from one hole to the next IN the shield. Someone mentioned the word waterproof. PLs are NOT waterproof. The best you can do is to make sure moisture can't get into your connection on either side of your connector. Fully seal several inches either side, multiple layers. I haven't used it in years, but I used to use Scotch Kote. A layer of 33 or 88 tape, Scotch Kote, and another layer of tape, each one extending beyond the last layer does a pretty good job and you'll pull brand new connections out of it 10-20 years later.

But ^FC5; left no doubt! But why not let the thermostatic controller do its thing? And, if it is kicking up to high speed in a QSO, you must be doing some very high duty cycle QSOs, i.e. talking continuously or working AM with long transmissions. Mine never seems to go above about 4, when pushing things a bit, unless I'm on 6M, then it will run a bit higher during long ones. What does your thermometer read normally? Mine occasionally goes above 51C, where the first audible fan noise appears, but very quickly drops off after that. I also monitor the exhaust temp with an electronic sensor in the grill of the fan. I'm quite surprised how cool things run in the auto mode (norm). Temps will run higher if you are running some reflected power too.

Not accurate at all. Most manufacturers say to stand the beam up so it is pointed straight up into the sky, reflector down, to do such checks. I still don't trust that, but is better than having it parallel to the ground. Keep everything (including yourself) away from the elements during the test.

In contest situation, you might not get it as hot as a long winded rag chew transmission. I don't contest, but I've gotten it hot enough that it hits the high speed fan mode. I would expect a slight sag when it gets hot, but would head off the heat by going into the menu and changing the fan control from NORM to 3 or 4 (depending on your condx) to keep higher minimum fan speed. That fan is a screamer when it hits 70C. Don't forget to take it back to NORM when the contest is over. That will save a lot of wear and tear on the fan.

However, there is something similar happening on the > frequencies below 160M. At this point, I cannot duplicate what you saw. But... I've just made a fairly extensive test run on all bands (except 60M) because of my <160M problem mentioned above. At first, I only checked the AM broadcast band and lower, but then thought maybe I should check all of the bands and did so, all the way to six meters. Since I retired and lost access to the IFR to generate reliable signals for testing, I used some local/regional AM broadcast signals for that portion of the spectrum. To check the frequencies under the BC band, I used local/regional LF air-nav beacons. The frequencies below the broadcast band were where the problem was initially discovered, specifically 60KHz WWVB. To keep sensitivity of the meter fairly high, I kept the strength below S-9 for all readings, except one or two more local broadcast stations. I did it with either the attenuator, or tuning to the edge of a filter in a couple of places. I also have the XG3, so used it for all of the later readings on all ham bands (again, I didn't check 60M). When using the XG3, I used 50uv signal with attenuator on for about an S-7 reading on most bands. Be aware that the S-meter calibration on the TS-590 is not 6db per S-unit below S-9. This is a personal aggravation, but most of the manufacturers seem to have a similar problem. Generally, in all of the ham bands, I can see ONE BAR of S-meter drop on the TS-590 when putting the KPA into OPERate VS STandBY. That's not a scientific measurement, just an observable change. It is also pretty insignificant, but it is very repeatable so does exist. In some cases there was no noticeable drop, so I slid off to the edge of the filter and adjusted for one 10Hz step above the threshold of the S-meter bar being lit and then put the amp in OPER position to see the change. There was always a change, but sometimes I had to make that tweak to see it. The spectrum below 160 meters is much more drastic. Broadcast signals suffer lots of signal loss, air-nav signals disappear except for locals, and 60KHz WWVB is totally missing, along with all noise of any kind from the antenna. Switching the antenna in and out, had no effect on noise, not even a pop is heard in the speaker when switching antennas or disconnecting connectors when the amp is in OPER position. In STBY, all sounds normal. Generally speaking, the broadcast band could be summed up by saying, the lower in frequency you go, the more loss you are going to see when switching the amp in and out. It varies from an S-unit or two, to several S-units at the bottom of the band. Below that, it gets much worse. Only the strongest signals get through in the 250-350KHz range, and just about nothing makes it below that. One might ask why not just turn the amp off when not listening to the ham bands. Well, because I shouldn't have to, for one thing. For another, I don't always remember to. These results are also being sent to support. I don't know if there is a pin-diode problem on mine, or if this is to be expected. I don't like it, but can obviously live with it if there's nothing to be fixed.

My answer won't help you a bit, because, as you already know, you have an abnormal installation. However, I do use whole house and I use more than one. There is one at the entrance where the buried cable comes out of the ground and enters the house. There is a second one at the old entrance that is fed directly by the new underground entrance via long line. Third, there is another one located at the shack 230 line that I ran from the old entrance when I first bought the house. All of these units are standard 220-0-220 units, none are poly-phase. I've been using them for some 40 years. A tidbit of info for you. General Electric units used to cost $30 each. I was charged over $120 for the last one I bought. When I questioned it, I was told that the prices shot up when the marketing department got hold of the product. That was many years ago. I paid no attention to the warranty. I don't expect them to do a thing about it if there is any damage. I just bought the best protection I could afford at the time. I wouldn't pay today's prices you quote. Insurance is cheaper. > Would it make sense to install the unit at the old panel > instead of selling it? It does to me, but then I am not worried about the wording of the warranty, and I don't have a poly-phase installation where voltages are odd. All of the above is my OPINION, and could be incorrect technically. YMMV.

[Elecraft] KPA-500 construction problem/question
I received my KPA recently as a kit. Assembly has gone well to this point. However, I cannot get the fan connector to slide down over the very long pins on the PC board. They insert and feel like they should, and like they are engaging properly with the pins, but it lacks 5mm of going on flush with the plastic to plastic contact. The pins appear to be twice as long as they should be. I could clip them, but won't do it until I know that's what I should do in case I'm doing something else wrong. I have pushed and wiggled so hard that I am flexing the board more than I want while trying to get the connector mated. Anyone else have words on this? Yes, it is the right connector (P7).

Absolutely. Make sure you use good quality connectors, cables, etc. If possible, plug the wattmeter directly into the RF output on the back of the rig (NOT the tuner or amplifier), using a double male if possible, and plug the PROPER, good quality dummy load directly into the wattmeter. Remember, every connector you go through, loses you fraction of a db. How many connections, cables, etc., does it take to equal one db of loss? Not too many. One db is 26%! If you lose 1db getting between the output port and the load, the load will only see 74W with 100W output from the transmitter. Something to think about. A typical old style tuner will lose you around 5 watts or more.
