Re: [Elecraft] 43 Ft Vertical and Elecraft Tuners
Remember the old Hy-Gain Hy-Tower ? It had tuning stubs brought out from various places in order to provide resonance on 10, 15 20 M, maybe even one for 40M. I have a manual around here but am too lazy to go find it. Anyway, I believe it was 57 feet overall and was rated for 80 - 10 M. You could add a base loading coil and an additional length of wire off the top mast for 160M. With an adequate radial system, they were the cat's meow of verticals back then. I always wondered how the connection points for those resonators was determined. Probably to limit interaction with other bands (??) Maybe some sort of similar set-up could be done with parallel wire stubs. I remember trying to tune a four pair parallel wire dipole for 20, 17 , 15 and 10 M. What a bear. Tweak one band and it would screw up the others. I finally got it tuned, but had to completely replace all the wires since I had chopped and re-soldered all of them so many times. I used ½ PVC pipe spreaders which kept the four wires about 2 from each other. Once up, it would have been impossible to re-deploy due to tangles. 73, Charlie k3ICH - Original Message - From: Jim Brown j...@audiosystemsgroup.com To: elecraft@mailman.qth.net Sent: Tuesday, September 03, 2013 11:03 PM Subject: Re: [Elecraft] 43 Ft Vertical and Elecraft Tuners On 9/3/2013 7:30 PM, Fred Jensen wrote: With the KPA500 at 500W, on 40m, I get a lot of RF from the GAP screwing up things like the WinKey, the laptop, and various other digital gadgets.

Of course you can operate the K3 in low power transceive on any frequency from 490-KHz to 32-MHz if in the TEST mode. Only issue is VFO readout is the IF and not the operating frequency of a converter or transverter. But say you use 3.472-3.478 MHz as your IF? Your LO would be 3.000 MHz. This could even be a DDS oscillator locked to a 10-MHz reference. A simple mixer and LO without filters would work 0-500 KHz (maybe). The wider issue if using other ham transceivers that only operate in the ham bands. My K3 has the EXREF board for referencing to an external 10-MHz source. This enables 0.1 ppm accuracy. A 10-MHz LO is 1-Hz stabile. 73, Ed - KL7UW At 03:58 PM 9/10/2013, Jim Miller wrote: It would really be nice if K3 would support 80m as a transverter frequency.

Re: [Elecraft] Elecraft SSB Net Announcement
I know it would take a few more net control volunteers, but the Collins Collectors Association net on 14.263, Sundays at 2000Z usually has at least two net controls located at (more-or-less) opposite ends of the country. They start with buy/sell/swap and then take check-ins by call area, starting with 1,2,3,4. Then 8, 9, 0, 7, 6. This attempts to follow the general propagation on 20 M and they stress that you check-in from the area your are transmitting from rather than your call. Mobiles, DX, and QRP stations are given priority and are specifically listened for every few minutes, taken anytime, anywhere. Admittedly, I just heard about the Elecraft net, so I don't know how long it runs, or whether this format would be practical. The CCA net is one of the oldest running Equipment Specific nets and if on a non-Super-Bowl or obnoxious contest weekend, can run over 4 hours. This puts us at 8PM EDST, so propagation must be taken into account. I have, on many occasions, checked in with my KX3 barefoot and gotten great signal reports not to mention some incredulous comments about signal strength. As you might expect, most 100 watt and up ops can't believe you can actually make contacts running 10 watts. (You don't have to be running Collins, just have an interest in it.) I might add that I do NOT have any spectacular antenna either, just a little Cush-Craft LPDA at 55 feet. As a slightly off topic comment, I didn't have any luck trying to check in a couple weeks ago with the KX3 and a 6 foot diameter Mag-Loop, but conditions were not good either(sour grapes). 73, Charlie k3ICH __ 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] Filters for mixed JT65 and JT9 HF
I believe that figure of 3400 Hz is the AUDIO bandwidth which is equivalent to an AM bandwidth twice that, or 6.8 kHz. If I am correct, then you can most certainly take advantage of your 6 kHz AM filter which will limit your broadcast audio bandwidth to 3.0 kHz. The 15 kHz filter will get you an extra 400 Hz.of audio, but is probably not practical due to the excessive bandwidth. Save that one for FM. 73, Charlie k3ICH On 10/7/2013 4:51 PM, Joe Subich, W4TV wrote: On 10/7/2013 4:39 PM, Bob wrote: Just be aware that current DSP firmware in the K3 limits the receive bandwidth to something around 3400 Hz.

Re: [Elecraft] OT: Installing PL-259's
It makes an extremely rugged and reliable connection. You could literally support your entire body weight from the cable without pulling it out of the connector. Alan N1AL I agree, try THAT with an N connector. I have never concerned my self with the fact that the center insulation might melt. I simply make sure that the cable and connector are held motionless during the soldering AND cooling process to follow. So what if it softens a bit, it'll solidify again as it cools. Like most hams, I have installed many hundreds of UHF connectors over the years on RG-58, -8x -213. Every failure has been due to my not catching a single strand from the shield.

The larger one (don't remember which one) can expand the female center socket. If you switch to the smaller version male after using the larger one, you may get an intermittent connection. You can tighten the female with a dental pick. We mixed connectors when TV stations switched from UHF to BNC for video. We found this issue years later! All BNC males are not the same.

Re: [Elecraft] Internal Antenna Tuner and SPE Expert AmplifierQuestions
The only possible situation where the connection you describe would function is when the INPUT SWR to your amp is not good. This is a quite common method of matching HB amps where their input impedance isn't THAT bad and the builder doesn't want to bother with a separate set of switched input matching networks. An external tuner, or one inside the amp, such as an LDG for example is used to match the tube(s). However, in order to do this, you have to let the input tuner do it's thing only when you have a good 50 Ohm dummy load on the amp. THEN, after the input is matched, you can switch in your real antenna tuner and adjust it for best SWR to the antenna. At this point, it is essential that the input auto tuner is NOT still trying to find a match. 73, Charlie k3ICH - Original Message - From: Don Wilhelm w3...@embarqmail.com To: elecraft@mailman.qth.net Sent: Monday, December 09, 2013 8:55 AM Subject: Re: [Elecraft] Internal Antenna Tuner and SPE Expert AmplifierQuestions Mark, The short answer is no. __ 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] Would anyone like to see an all-mode VHF/UHFoffering from Elecraft?
I've been on 50 MHz since the time when DXCC was impossible since there were not 100 countries in the world that had six meter privileges *. I even have a QSL from a pirate in Scotland (back in the 70's ??) before they got the go ahead after ch1 TV was shut down in Europe. Every propagation mode known happens at one time or another on 50 MHz. Moonbounce, E skip, Tropo, F2, Aurora, Meteor scatter, Back scatter, and good old Ground wave if you're diligent. There are many beacons all around the world below 50.1. Check there first before you say the band is dead. Two meters is right behind. About the only mode I haven't heard there is F-2. There's even E skip on 220 Mhz. There's LOTs to do above 50 MHz. That said with all the enthusiasm, I can't really see Elecraft making a dedicated VHF/UHF radio when they already have some very good transverters available. I would have to agree that effort to fill some holes on the P3 would be of more interest to me. 73, Charlie k3ICH * 140 countries confirmed on six meters, plus WAS, WAC, and 37 states confirmed with NO moonbounce on two meters from here in Virginia. - Original Message - From: Edward R Cole kl...@acsalaska.net To: Elecraft@mailman.qth.net Sent: Friday, January 31, 2014 2:01 PM Subject: Re: [Elecraft] Would anyone like to see an all-mode VHF/UHFoffering from Elecraft? Ted, You really expected a VHF contest to sound like Field day on the HF bands? That tells me that you do not regularly operate VHF-ssb. I have been pleading with the FM repeater HT hams for years to explore the fun of VHF-ssb/cw/digital modes with multi types of propagation and the response is they don't have the time, the cash, the know-how, the property that allows antennas, etc. etc. There is plenty VHF multi-mode radios available plus a wide assortment of transverters, plus very economical surplus multi-modes from past years. Radio supply is not the problem. With the exception of 2m-eme using digital modes there is just not much interest by the usual VHF users and especially new hams. Satellite use has dwindled due to lack of cheap launch capability so new satellites are essentially orbiting repeaters for the most part. A radio with the capabilities you request will be in the $3000 class (If not more). A K3/10 + transverters will accomplish this if you want Elecraft equipment at less than that (I think). Or one could buy the KX3 and add the 2M module when it comes out. Then add transverters for 222, 432, 1296. In 2012, I sold my FT-847 to purchase a 222-28 and 432-28 transverter to go with my K3/10 which I already had 144-28 and 1296-28 transverters.

Wire a small grain-of-wheat incandescent light bulb to the unused antenna feed and fire up the transmitter. If the bulb lights brightly, you need some protection.

Re: [Elecraft] adjacent antennas and potential radio damage
Connect a grain-of-wheat light bulb across the unused coax and gradually increase transmit power. I know this is a rather un-scientific, crude test, but simply put, you're in big trouble when it glows! I tried this with a 600 foot Beverage that is, at it's closest point, 50 feet from any transmit antenna. On some bands, I could run a kW but on others bands, the bulb was bright at 150 watts out I now have a Collins RF Overload Protector (622-0908-001) permanently in the Beverage feed ! Better to use a GOOD antenna switch with published maximum isolation, or unplug the unused antenna. 73, Charlie k3ICH - Original Message - From: Julie Royster jsdroys...@nc.rr.com To: elecraft@mailman.qth.net Sent: Wednesday, April 16, 2014 11:06 AM Subject: [Elecraft] adjacent antennas and potential radio damage Thanks to those who wrote me privately as well as those who replied on this list (KL7UW and K4NH ) regarding the possibility of damage to one radio from another radio transmitting on a nearby antenna. For the benefit of all I am pasting below highlights of the useful information I received. MANY THANKS! I learned a LOT from you kind folks. Julie KT4JR Dick at Elecraft said: At 5 watts it's usually not a problem, at 450 watts, you want to have a bit of room (maybe hundreds of feet) between antennas. The radios have some protection from overdrive. Carefully planned with antennas end to end or facing different direction with enough space it's possible to share a band with multiple K3s. But if the antennas are coupling sufficiently, it can be destructive to the front ends of the radios. I can't offer any guidance better than you've receive thus far. Every multioperator contest or Field Day station has to deal with this problem, and there are solutions, but they require some effort, either bandpass filters to keep energy from nearby transmitters on other bands, or antenna placement planning, or some combination. AB9CA/4 said: There are certain orientations which might allow simultaneous operation of the two stations. If one antenna is a vertical and it can be placed on a line perpendicular to the mid-point of the Vee you should be OK. This is when the base of the vertical lies on the vertical part of a 'T' arrangement with the Vee forming the horizontal top of the 'T' (looking down from the air). Place them as far apart as possible. There is minimum interaction in this configuration. With chokes in place and proper dress of the feedlines you could get maybe 60 dB of isolation between them... (On Field Day) Our club has used two stations on the same band, usually 20m, with success. One on CW the other on Phone. We did it with two wires arranged as I mentioned earlier, in the 'T' configuration. Especially note that damage can occur even if one rig is turned off. The antenna is still connected internally with power off. To be certain of avoiding damage it is best to disconnect the antenna from any rig not in use. And when you connect them be certain of what band the other station is on (and make sure you are not on it!). __ 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 Message delivered to pin...@erols.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 Message delivered to arch...@mail-archive.com

I have the capability to measure it, but I have not done so. If it's going through any DSP, there will be some, probably a few msec. I would not expect it to be a problem. The difference between what we hear through bone conduction and the actual sound of our voice is mostly the difference in frequency response between the two paths. We can get a better approximation of how we sound to others by talking straight into a hard wall at a very close distance. Now, our ears hear our voice bouncing off that wall with very little loss. There's a phenomenon called precedence effect that was first documented by Joseph Henry around 1850 (the guy whose name is on the unit of inductance in recognition of his inventions involving magnetics much earlier). Precedence effect describes the characteristic of human hearing that if we hear the same sound from more than one direction, we will hear it as a single sound, coming from the direction from which it arrives FIRST even though a later arrival is louder. There's a limit -- a loudness difference of more than 10 dB will break precedence. Yes, long delayed echoes can make it difficult to talk or to play music. In live sound reinforcement, delays are produced by DSP, and also by the time it takes sound to get from speakers over a stage down to the audience. Delays more than about 35 msec will start causing fatigue or discomfort, and I've heard very professional announcers slow down and stop talking with delays in the 80-100 msec range. 73, Jim K9YC __ 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 Message delivered to wun...@wunderwood.org -- Walter Underwood wun...@wunderwood.org __ 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 Message delivered to pin...@erols.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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] QRQ CW
Back when I worked at the old Microlog Corp in Gaithersburg MD in the late 70's, we found that a lot of rigs couldn't be keyed much faster than about 50 WPM. Key click filtering etc., made mush of the faster CW.A keyed string of dots looked like the output of a half wave rectifier ! To get around this limitation, in order to run 100 WPM CW, we'd revert to AFSK keying, copying the Mark frequency only.worked like a proverbial charm. It was like having our own private encryption system as nothing but a computer assisted copy system could decipher it.We never really asked if it was legal though. And, to my knowledge, there was and still is NOTHING out there as good as the decoding algorithms those programmers wrote. (The main one just happened to be the president of the company.) I tested every piece of competitive equipment I could get my hands on to prove this point. Microlog was the absolute king-of-the-hill for CW copy, hand sent, bug sent or otherwise.

I used to be able to copy 50 wpm pretty consistently in my head and I have a 40 wpm W1AW code proficiency certificate. But it makes no sense to go that fast in a contest unless you are content to work only other QRQ stations. I think around 30 wpm or so is reasonable. Even operators who can't go quite that fast can probably get your callsign after listening for a minute. Then when they call you at 18 or 20 wpm you can slow down to work them and then speed up again.

Re: [Elecraft] OT 4M
Yeah, that was SUPOSSED to happen, but in true guvmint fashion, it didn't quite work out that way. (Where have we seen THAT before?) There's still a LOT of analog low-band TV, so the chances of a 4M ham band over here in the colonies, is just about dead.

It checked the CW copy, aligned the AFSK generator and verified CW PTT keying, all in that 3.2 K of RAM with neat graphic indicators on the screen for the production testers.

Re: [Elecraft] OT: Learning the code
NO ! Start with the long characters FIRST. We (at Microlog) developed an automatic Morse Trainer for ( an unnamed guvmint agency ) where we simply automated their technique. The first four characters they taught, if my memory is correct, were L, P, Q C. The last ones to learn on the list were E, I, T, M The logic is such that when first learning the code, if you hear a figure 1, you will change your mind four times.is it E, A, W, J, or finally the figure 1. This method teaches you to learn the sound of each character rather than what it looks like printed as dots dashes. Proof of the pudding.my son passed his Novice code test after just two weeks of 20 min per night starting from scratch (NO Morse ability at all to start.). And yes, the characters were send at 15 WPM rate with enough space to equal 5 WPM. Curiously, when asked to send, he would snap out the letters at around 12 to 15 WPM on a hand key because that's how he heard them. 73, Charlie k3ICH __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] RF in the Trees
Don't rule out traps. Also, the RF Connection and probably others, sell a nice stranded copperweld wire that has a black polyethylene insulation. If I remember correctly, it is 13 ga and is ideal for antennas. For all practical purposes, it doesn't stretch, is fairly slippery and only a little springier than hard drawn copper. I use those double ferrule aluminum crimp on's that are designed for flexible wire cable to hold everything together. I was concerned about them holding through the poly insulation, but the following antenna has been up for about ten years now. It consists of a double (fan) dipole with a pair of 80 meter traps in the top leg for 160 80 M coverage and a pair of 40 meter traps in the lower leg for 60 40 M coverage. It is fed thru a 1:1 balun with RG-213 and is tuned for resonance. Basically, I operate SSB 99% of the time, so the antenna is tuned for that end of the bands. An MN-2700 tuner in the shack takes care of small excursions from resonance. It's only up about 50 feet, so performance is what you'd expect. It's not straight either and is sort of a lazy Z, being strung between two 55' telephone poles that are 105 feet apart. The ends droop down at about 45 degrees to tie-off points in trees. A compromise? Yes, but it works. 73, Charlie k3ICH - Original Message - From: Jim Brown j...@audiosystemsgroup.com To: elecraft@mailman.qth.net Sent: Thursday, June 26, 2014 1:55 AM Subject: Re: [Elecraft] RF in the Trees On 6/25/2014 5:43 PM, Dauer, Edward wrote: So, I've been selecting two of the tallest candidates a couple of hundred feet apart and stringing a stout nylon rope between them. In the middle of the cord I attach the balun for the Vees, thereby allowing the legs to be in the clear, moveable from side to side, and tied to smaller (8') trees at their distal ends. In one variation on the theme I had a 40 meter dipole as the center section of the supporting rope, tied to the same balun as an 80 meter vee. In another I tried a linear-loaded 80-meter Vee, about 45' on a leg; it loaded fine but didn't perform as well as the full length version. If you can suspend a flat antenna between two tall trees, why would you want an inverted vee, which is a less effective radiator? Your two trees 200 ft apart could support a full size 80/40 fan and a 20/15/10 fan, in line with each other. A high 80/40 fan is a VERY good antenna, and is easy to build. My technique has evolved to starting with #8 bare copper from the big box store, stretch it VERY slowly between a tree and a trailer hitch until it breaks. Do this carefully where there's no one around to get hurt. Now you have #10 hard drawn copper, which is pretty strong, and pre-stretched. Use that for the longest dipole in each fan. Use #12 or #14 THHN (house wire) for the other elements. I make spacers by cutting 1/2-in PVC conduit into lengths of about 16 in for 3-wire fans, and about 12 inches for 2-wire fans. 5-6 ft between spacers is a good rule of thumb. Hold the spacers in place by soldering short lengths of copper around the spacer to the bare copper of the long element. The higher your antenna is, the more robust your center insulator should be. A high 80/40 dipole (80 ft or more) will be closer to 75 ohms than 50 ohms. A 20/15/10 fan will be close to 50 ohms. Use RG8 or RG11 depending on the Z at resonance. Don't waste a dB or two with small coax. My 110 ft 80/40 fans are fed with Belden 8213. For weights, I fill 6 gallon water jugs with dry sand, and tie one to one end of each span. The other end can be fixed. I have pulleys high my trees. If you don't have a pulley and weight, your antenna WILL end up on the ground, and it won't take a big storm for that to happen. My HF antennas are all at the 110-120 ft level in a dense redwood forest that towers 50-75 ft above them. They work. My seat of the pants observation is that attenuation increases with frequency, and is greatest with vertical polarization. 432 MHz is a waste of time, 2M sort of works, and 6M works pretty well. For an analysis of the value of height, study this. It supports the statement earlier in this thread that a high dipole beats a low tri-bander. http://k9yc.com/VertOrHorizontal-Slides.pdf When Fred observes that the ends of antennas are hotter, he means that this is voltage maxima and a current minima, so good insulation is needed to whatever the antenna is attached. I once melted heavy dacron rope that was tied directly to the end of said dipole (well, twice, actually). The extra ingredient was that it was wet.

Re: [Elecraft] RF in the Trees
The professional Arborists use a cloth or leather bag filled with lead shot and something called tangle-free line or similar to throw up in a tree so that they can pull up a supporting rope for tree trimming etc. From what I've seen, the bag is about the size of a tear drop shaped golf ball. The idea of the shot instead of a solid weight is to make the bag less damaging if it hits your house (or window) on the way down. I have a neighbor who's son is an arborist, so I've watched him on several occasions. It DOES take a bit of practice, but the line never seems to get tangled. I tried this with a few lead fishing weights on some thin nylon line and it was a disaster. The secret is to use a thick enough line so that it won't spin around itself and (mysteriously) tie itself in a knot way up in the tree. 73, Charlie k3ICH - Original Message - From: Fred Jensen k6...@foothill.net To: elecraft@mailman.qth.net Sent: Thursday, June 26, 2014 8:05 PM Subject: Re: [Elecraft] RF in the Trees On 6/26/2014 4:12 PM, Rick Bates, WA6NHC wrote: This may be off topic, but in light of it being Field Day Weekend in the US It's radio, Eric will probably see it as relevant, unless we overdo it, which we do at times. :-) The arrow has an issue because it gets hung up or in branches and doesn't have enough mass to pass through some branches or allow gravity to pull it down.

Re: [Elecraft] KXPA-100 to ICOM PW-1 amplifier
Just to clarify... use of ALC with the PW-1 is not to adjust drive power. That's a bad practice. You MUST use the ALC line because the amp uses this as a primary means of protection. Without ALC, a fault condition can damage the amp. 73, Josh W6XU Well, yes it is when connected to an Icom transceiver it is used precisely to control drive power.

Re: [Elecraft] P3
Even if you manage to bring out the IC-7600's IF, the problem is that the radio's IF is around 64 MHz but the max frequency that the P3 can accept is about 33 MHz if I remember correctly. Simply put, there's no easy way do connect a P3 to the IC-7600. (If anyone knows of a way, I'd sure like to hear about it.) However, there ARE methods that will provide a much improved panadapter/waterfall display over what shows on the radio's screen. There's an easy mod that uses a Mini-Circuits or other brand, two way splitter to bring out the IF scope signal. You basically pull the coax line from the IF to the scope input on the board inside the radio and insert the Splitter such that one of it's outputs goes to the original scope input connector and the second splitter output goes to the outboard device. Usually a simple dongle SDR or LP-Pan is used with a computer program for a much improved panadapeter waterfall display. Another somewhat more costly way is to use the same splitter between the Rx-IN RX-OUT connector to drive something like and SDR-IQ or as I am doing, a QS1R SDR receiver running SDRMAX V + Omni-Rig. The SDR basically runs in parallel with the IC-7600 and Omni-Rig allows master/slave functions between them. It's a lot of stuff to turn on, but you'll be rewarded with a spectacular screen of info. 73, Charlie k3ICH - Original Message - From: anel...@min.midco.net To: Elecraft@mailman.qth.net Sent: Sunday, August 03, 2014 1:22 PM Subject: [Elecraft] P3 Has anyone hooked the P3 to an Icom IC-7600?

Maybe mechanical was not the proper choice of words.

Re: [Elecraft] very small 20A switching PS
Curiously, I have found that certain switching supplies can actually deliver quite a bit more peak, or very short duration current than their ratings would imply. For example I was testing a TS-480 HX running from a 25 Amp Astron switcher and was getting the full rated 200 watts out momentarily with barely noticeable voltage sag. At this level, the total supply current was around 35 Amps. Now, admittedly, I did not look at the DC waveform on a scope, but the SSB transmit audio sounded fine which to me, implied it was clean. I'll have to try again and look at the waveform. It'll have to be with resistor loads since I don't own the HX now. 73, Charlie k3ICH - Original Message - From: Charlie T, K3ICH pin...@erols.com To: elecraft@mailman.qth.net Sent: Sunday, September 21, 2014 8:00 AM Subject: Re: [Elecraft] very small 20A switching PS Gamma something.

Re: [Elecraft] HF noise.....10 M
Anyone have any idea what those weeblies are on ten meters? They typically start high in frequency and flitter past the receiver then stop abruptly. They sound like a very unstable oscillator, almost like there's a random (or encoded ?) narrow frequency modulation as they move lower down the band. They are quite noticeable on the panadapter display and appear to have several rates of downward frequency shift. Also, occasionally, a wide band hump for lack of a better word. will appear in the display and pop off a second later as quickly as it came. I've tried tracking them down, but they all seem to not be coming from anything in close proximity to me. I've heard these weeblies for many years. They're not a QRM problem since they're only in the passband for a second or so and occur at about 1 to 5 per minute. It's just that this is the first time I've been able to see them on the screen. The display kinda reminds of the Quark capture displays we used to see. 73, Charlie k3ICH - Original Message - From: Thorpe, Jeffrey jtho...@liberty.edu To: elecraft elecraft@mailman.qth.net Sent: Tuesday, October 14, 2014 9:39 AM Subject: Re: [Elecraft] HF noise.30m Does the CW signal show up on a particular schedule?

Re: [Elecraft] Interesting K3 QRM problem
I'd go for a series tuned trap to ground. That would seem to the least disruptive, if that's the right word, to your system. I remember working at Vectrol in Rockville MD fairly close to an AM transmit antenna site. We designed built big three phase SCR controllers and of necessity, had to isolate any oscilloscope's chassis ground.You could always see the low level AM signal on the scope. A similar trap worked, but it would have required dozens of them to cover all the scopes etc.. Luckily, when you're looking a 60Hz waveforms, we just ignored the BCI. 73, Charlie k3ICH - Original Message - From: Vic Rosenthal 4X6GP/K2VCO k2vco@gmail.com To: Elecraft Reflector elecraft@mailman.qth.net Sent: Thursday, October 23, 2014 6:58 AM Subject: [Elecraft] Interesting K3 QRM problem I live about 3.3 miles from a 50 kW BC station on 1080 kHz. It is on 24 hours a day, transmitting in Arabic, not that that matters. I have two antennas: an R8 vertical and a Pixel Loop receiving loop. With either antenna, I hear a wideband noise on my K3 that is synchronized with the program material of the BC station on the 14, 10 and 7 MHz bands. I first determined that it was not affected at all by the attenuator in the K3. So I assume that it is not caused by front-end overload in the K3. I noticed that if I listen on the Pixel Loop via the K3's RX ANT input the noise completely goes away when I unplug the R8 from the K3's ANT 1 connector! I also noticed that the noise is reduced when I bypass my amplifier or my SWR/wattmeter, which are connected between the ANT 1 connector and the R8. Reduced, but not eliminated. I conclude that what is happening is that the BC RF is being picked up by the R8, and the diodes in the wattmeter and the amplifier and the K3 finals are creating IMD products which I am hearing. The K3 seems to be the major contributor. I am thinking that maybe the IMD products are being re-radiated by the R8 and picked up by the Pixel Loop. I tried one more experiment: I have a BC band filter which is used with the MFJ antenna analyzer when there are nearby BC signals. Sure enough, putting this in series with the K3 ANT 1 connector kills the noise. Of course I can't transmit through it. Has anyone had a similar problem? I am thinking that the solution is a highpass filter or trap at this spot.

Re: [Elecraft] KX3 on SSB Mobile
My personal opinion is that you're setting yourself up for a very frustrating experience. Yes, you will eventually make some contacts, but unless you'll be spending a lot of time in the vehicle, your contacts per trip will probably be rather low. Technically, I agree with Rick that you need the outboard amp. However, for what you'll pay for the amp, you can buy a radio that was designed for mobile. I have two Kenwood TS-480S/AT's in mobile service and I find it is the best mobile rig I've ever used in over 40 years of mobiling.With tunable antennas such as the Tarheel that Rick recommended, I'd go for the HX version with 200 watts output. It WILL make a difference, especially when you're operating on 20 M and below where even the best 8 foot antenna is a severe compromise. Even though I've had a radio in the car for many years, I am not a serious mobile op. I use an old solid SS bugcatcher mast and several Hustler resonators. From experience, I operate 95% of the time on several bands (20 40 M) , so I never felt the need for an expensive all-band antenna and a couple resonators are adequate for me. One trick I've found to increase their efficiency is to use the next higher band coil and add length to the top whip. A 4 foot whip will work fine on 20 M using a 15 M coil. I also removed enough turns from a 40 M coil to also use a 4 foot whip for resonance. Mobile operation can be fun, but QRP mobile, at least to me would not be. Now, if you're mainly interested in listening, then it's a different story. 73, Charlie k3ICH - Original Message - From: Rick Bates, WA6NHC happymooseph...@gmail.com To: elecraft@mailman.qth.net Elecraft@mailman.qth.net Sent: Friday, October 31, 2014 12:30 AM Subject: Re: [Elecraft] KX3 on SSB Mobile Like any great station, most of the budget should go into the antenna. The Hustler will load and it might even radiate, but the resonators have low Q and are not very efficient. I just gave mine away last week, I now use a Tarheel (screwdriver) on my truck. If your budget insists on that choice, at least make double sure that is it as high as you can safely afford with everything bonded well to (and ON) the vehicle for the best efficiency. If you get a screwdriver antenna, same rules but get the coil as high as you can and use a capacity hat instead of a tall whip. Next you'll want to pay attention to how you power the radio. Cigar lighters are notorious for noise because they are not well grounded and often have other devices (noise makers) on the same circuit. Find a better power source, preferably connection directly to the battery (automotive self-resetting circuit breakers at the battery, fuses near the radio; BOTH leads to the battery AND both fused). The battery will act as a HUGE capacitor, keeping a lot of noise out of the rig. Once that is taken care of, you can set up your transmitter audio as you've been instructed and there are plenty of 'scopes out there to get accurate reports. I might also cut the lows in the TX EQ which helps add more 'punch' but don't overdo that or it sounds like crap (pinched noise while breathing helium). Don't forget that since it is a wider signal, SSB won't have near the energy you're used to (you'll need more power than you do on CW). So it can be done. The question (for you): is the time and frustration worth the fewer contacts you'll make (compared to a 100 watt mobile). For me, life is too short for QRP but some folks thrive on it. I'd seriously consider adding the KXPA with tuner into the mix. Then you can consider one of the other larger amps... ;o) 73 es GL, Rick, WA6NHC __ 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 Message delivered to arch...@mail-archive.com

We make a #33-100 KX3 PX3 DC Power Splitter which helps facilitate neat cable management for users of the KX3 PX3 (https://proaudioeng.com/accessories/). If you are using straight plugs for your headset, you can position them as much as 2.25 apart and still use the splitter. You could also reverse the positions, in which case if you are using the splitter the PX3 can be positioned up to 1.25 to the right of the KX3, and you would have to use a right-angle BNC for the antenna connector. An additional 1 or more of separation can be achieved by removing the heatshrink and tape holding the two conductors of the splitter if necessary.

Re: [Elecraft] OT: Good time to buy Begali products
I think there's a matter of semantics here. I believe the comment that the exchange rate will not affect Dayton prices can be interpreted as Begali will NOT purposely raise their prices BECAUSE of the exchange rate. As the dollar gets stronger, it means their prices will yield the same in Euro as before, except that it will take fewer dollars to buy them. 73, Charlie k3ICH - Original Message - From: Jim Hoge knowk...@verizon.net To: Elecraft Reflector elecraft@mailman.qth.net Sent: Sunday, January 25, 2015 11:44 AM Subject: Re: [Elecraft] OT: Good time to buy Begali products Regarding Begali's prices at Dayton, they are directly related to the exchange rate. Also, you are not paying for shipping. As for exchange fees, Paypal does a good job of making you dig for the information but you can determine the fee prior to making a transaction. To do so, follow these instructions: log in to your account, click on profile, click on my money, click on currency, enter the required information, then click on calculate. The last time I made a payment in Euros, I think Paypal added about 2.5 points to the exchange rate. Even with that, the cost of dollars to Euros is still at bargain levels compared to what it has been.I don't need any more keys but I must satisfy the K3's lust for a new one now and again so I, er, my K3 is sorely tempted to purchase another one given the current exchange rate. 73,Jim W5QM On Sunday, January 25, 2015 10:25 AM, Phil Wheeler w...@socal.rr.com wrote: On line prices are in Euros, so a more favorable exchange rate will reduce the price in $US -- if ordered on line.

Re: [Elecraft] Side KX and/or cover
Do most people who order the side panels also get the clear plastic cover? I'm trying to decide what, or if I need them. Bearing in mind that I'd saw a dime in half if I could spend it twice. I buy C-128 laser cartridges for my printer and they come in a fairly tough tubular bubble pack which just happens to be a perfect fit for the KX3, the Comet CAA-500 analyzer, or a 15A MFJ power supply. Each one makes for a package slightly smaller in diameter than a football (the brown pointed one, not the black white one). I don't do back-pack type operation, but they work fine for carry on baggage or the car trunk. 73, Charlie k3ICH - Original Message - From: dyarnes w7...@cox.net To: Elecraft Reflector elecraft@mailman.qth.net Sent: Saturday, January 31, 2015 11:51 PM Subject: Re: [Elecraft] Accessing KX3 buttons when using Side KX Hi All, I have the Side KX panels on my KX3, and it's really not a problem for me. As has been pointed out, there are fairly large slots on both sides through which you can access any of the buttons on either side row. I suppose someone with especially large fingers might possibly have an issue, but in that case (or anyway!) just use the opposite hand! It is no problem at all accessing buttons on the left side with the right hand and vice versa. By the way, the left panel also has the two buttons identified that need to be pushed to turn the KX3 on or off. So, they obviously thought about this when they designed the panels and determined the slot size. One nice thing about the panels is that their size (depth) does not extend much beyond the main tuning knob. So, if you KX3 fit snugly in whatever you were using for a case before, it probably will still fit with the panels in place. I was slightly concerned about that when I ordered the panels, as I had already selected a carrying case, but there was no problem, before or after--and it is a nice, close fit. Anyway, at worst I would say it is a minor concern.
