Re: [Elecraft] Testing anti-static mats - found one that works
How are you measuring resistance? Matt W8ESE On Wed, Apr 7, 2010 at 6:53 PM, Alan Bloom a...@elecraft.com wrote: It is important to use an anti-static mat to prevent damage to electronic devices when working on solid-state equipment. Since Elecraft is heavily kit-oriented this is a topic of interest for Elecrafters. Quite some time ago I did some testing on the Radio Shack portable anti-static mat and found that its resistance was way too high to do a proper job of bleeding off static charges. I then bought another low-cost mat from Jameco and it also measured way too high. I began to doubt my testing methodology (described in a previous message, copied below). So now I have bought a third mat. This one is more expensive, but unlike the cheaper mats it has an actual data sheet that specifies that it meets ANSI specs for anti-static performance. I figured if it also measured bad then my testing must be in error. But it didn't. Here are the results: Radio Shack P/N 276-2370 ($22.99) - 26 G ohms (26,000 M ohms) Jameco P/N 10584 ($16.45) - 44 G ohms (44,000 M ohms) Digi-Key P/N 16-1121-ND, (Desco 66164) ($38.18) - 41 M ohms The Desco mat's resistance is about 1000x lower than the cheaper ones! This mat is quite large, (2 x 3 feet, 61 x 91.4 cm) so if you buy one you may need to cut it down to fit on your workbench. It comes with a common point ground kit (that you have to install on the mat yourself) that provides a long wire with solder lug to connect to ground and a two-socket connector for connecting one or two wrist straps. The wrist strap and cord have to be purchased separately. It looks like Digi-Key P/N SCP172-ND for $8.95 should work. So the total cost is about $47. But the cheap mats are no bargain if they don't work. I tried cleaning the surface of the mats with some wipes that are especially intended for cleaning anti-static mats (Digi-Key MTT20-ND) and they did help. The Radio Shack mat went from 26 to 6 Gohms and the Jameco went from 44 to about 12 Gohms. But those numbers are still way too high. The Desco mat's resistance also went down, from 41 to 20 Mohms. The Desco mat came with a small spray bottle of Rezstore, their own brand of mat cleaner. By the way, the back side of the Desco mat is some kind of highly-conductive black rubber, apparently to keep the entire mat surface at equal potential. They warn that you should always use it blue side up because the resistance of the back side is too low. Sure enough, it was low enough to measure with my digital multimeter - about 80 kohms. So my recommendation is to buy a mat such as the Desco model that has a data sheet that specifies that it meets ANSI/ESD S4.1 or ANSI/ESD S20.20. If you already have the Radio Shack mat, then either replace it or at least clean it with a cleaner approved for ESD mats. (You're not supposed to use soap or detergent because it might harm the anti-static properties.) Gary KI4GGX recommends a product made by Techspray: http://www.all-spec.com/products/1733-QT.html Whatever you use, it is important to keep the mat clean. A word about my test procedure. Accuracy is not very good because I am trying to read the peak amplitude of a brief needle flicker. If I had an analog meter with a high-impedance input that would work better because the reading wouldn't change so fast. Also my sauce pans no doubt do not give the same answer as the ANSI-specified test probes. So overall, I doubt my measurement accuracy is better than +/- 50% or so. But for the purposes of this test that's good enough. In the test procedure below I had to substitute a 1.0 uF capacitor when measuring the Tesco mat in order to get a long-enough time constant to measure accurately. (Also, it's actually a Triplett meter, not a Simpson.)

The ESD Association http://www.esda.org has promulgated an industry-standard test for ESD mats, ESD S4.1. It is the standard specified by most commercial mats. I decided not to spring for the $70 to buy a copy of the standard, but other information I found on the web describes the test in general terms. It uses two circular electrodes, each weighted with 5 pounds, spaced 10 inches apart on the mat. The Point to Point Resistance is specified to be: At 40-60% RH: 10^6 - 10^7 ohms At 20-40% RH: 10^7 - 10^8 ohms At 10-20% RH: 10^8 - 10^9 ohms I don't know what the RH here in Santa Rosa was yesterday when I did the test, but I don't think it was very low since it has been raining recently and the ground is still damp. For sure the resistance shouldn't be below 10^9 ohms (1 gigohm) and probably more like 10^8 or 10^7 (100 or 10 megohms). I measured 2.5 x 10^10 ohms (25 gigohms), which puts the Radio Shack mat way out of spec. Test

Re: [Elecraft] Elecraft Amps
David, there is no reason they couldn't package it with the PA other than input source differences. If its a single platform, or use PA, we will include power conditioning with it. The cases where we dont the PA is used on multiple platforms and has to run from 1275, 704, 400 cycle, 3 phase etc. And it makes sense for the power conditioner to be a platform independent kit. If you look at most radios as well, they require the power supply external so you have the choice depending on where you are plugging it in or if you are running of batteries.

Re: [Elecraft] K2: winding T5
The solder blob method takes a little trick, you have to sit on the end of the wire long enough for the insulation to melt (heat has to transfer to the wire).

It is just as effective. Matt W8ESE On Mon, Feb 8, 2010 at 11:31 AM, lstavenhagen lstavenha...@hotmail.com wrote: Ok, thanks Don.

Of course if they have stock left over, you have a chance, but that can only be on older designs. All new designs will use RoHS-compliant parts.

Re: [Elecraft] Looking for a good battery/charging system for K1
If cost is not an issue, look into A123 battery packs, either thru buddipole or hfprojects, or you could order cells and roll your own. Matt W8ESE On Fri, Jun 19, 2009 at 7:25 AM, Michael Babineaumbabin...@magma.ca wrote: John : Here is a few battery suggestions for your portable K1 station. If you want 5W you will need a 12V+ pack. If you are willing to settle for about 3w out the K1 will hum along nicely at 9 to 10V. It is quite a miserly rig so you can easily manage a day outing with battery capacity in the range of 2 to 3 Ah. I use a couple of different packs depending on the circumstances. My suggestions : 1) a small sealed lead acid (aka GEL-Cell) battery in the range of 2 to 3 Ah - Walmart also sells a good little charger for SLAs for about $25 called the EverStart Battery Companion (1.5Amp trickle charger). It is actually a 3-stage smart charger perfect for SLAs that are = 2Ah. 2) 9v (actually closer to about 10.5V when fully charged) R/C NiMH battery packs The Radio Control packs you should be able to get at Radio Shack along with the proper charger. Radio Shack usually sells a combo pack with a charger (part 23-432) for about $20. These packs are in the 1500 to 1700 mAh range. If you go this route I suggest you buy a 2nd pack so you have a backup. Another good idea is to cut the leads on the pack and solder appropriately rated pico-fuses on both leads (these look like resistors) then put heat-shrink tubing over them and tape the leads against the body of the pack with electrical tape (the pic-fuses are a bit fragile so you don't want break them). (Hint, these packs also fit inside a FT-817 and make a good cheap internal battery for that rig.) 3) Go with rechargeable AA cells. You can buy 8 and 10 cell holders depending on what voltage you want (note that NiMHs are nominally about 1.2V when fully charged). You can find lots of these at WalMart, Radio Shack etc, along with 4 cell quick chargers. I would go with a reputable name (ie Duracell etc) rather than the no-name ones and try to buy cells that are in the 2000 mAh range. Note that the K1 will tolerate up to about 15V in so you can use a 10 cell holder if you are using NiMH rechargables. In practice I have found that a 10 cell holder with NiMHs will give 13+ V when fully charged which is perfect. For safety reasons, (both yours and the rig) I strongly recommend that you fuse whatever battery solution you decide on and don't forget that you need to be careful with NiMH packs as these batteries can generate a very very high current for a short period of time if shorted out. Needless to say this can result in burns or even an explosion. Best of luck Michael VE3WMB / VA2NB P.S. Another related idea. I standardized my QRP power connections on a 2 pin Molex connector (polarized). Most of my battery packs have a short pigtail with the female version of this Molex and I have a slightly longer length of wire that is fused and has the male Molex on one end and the appropriate coaxial power connector that fits into the K1. This allows me some flexibility in how I power my K1. For instance I have a cigarette lighter plug that has the female Molex so I can use this adaptor to plug my K1 into the cigarette lighter jack in my car if I want to operate from the car. For some of my otherQRP rigs like the ATS3 that have a different power connector I just made up a fused power cord that has the male Molex on it so I can use any of the battery options that I already have for the K1. I found that this modular approach works very well. __ 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

This 'flaw' in transistor theory only presents itself in high density IC if you read the article, and I would suspect it has to do with no longer being able to follow partical theory, which is what works for discrete transistors, soon as things get small enough, wave theory takes over, and common conventions are no longer valid, however maxwells equations always apply to both... its just the terms you ignored in certain cases start to become significant.

Generally true. I bought mine brand new (with employee discount) some years ago and have never regretted it. For once in my life, it's nice to have a no-compromise, reliable piece of test equipment.

Re: [Elecraft] BL-2 Connection To An Unbalanced Wire Antenna
Ahh now you are no longer talking about RF ground but the black art of EMI. Its not to difficult to determine RF ground, you have to have very good spatial visualization, the ability to hold the 3D model of the board, chassis and housing in your head, and you need to think like an electron. It takes practice, but being relatively inexperienced i've gotten the hang of it after being involved in the successful design of 2 radios, but then again I have fantastic mentors and elmers. In the end everything is explained by Maxwell's equations and if 1/10th of the ham population took the time to understand how these fantastic formula work and what they mean, 99% of this confusion and most of the half truths you see passed around as 'common knowledge' would disappear.

Perhaps the biggest concept drilled into me by the RF engineers I worked with at Motorola (I was a digital/software/comm engineer) is that there is no such thing as RF ground. RF can, and is, conducted on any path that it wants. This is especially true for the so-called ground and power paths, which while appearing to be well bypassed, still will carry RF currents. The problem was really drilled home when I had to track down a problem with a 450 MHz handheld data transceiver being desensed. The cause was the 250th harmonic of the microcontroller main clock, which placed a 14 uV signal on the receiver input. The signal was being conducted on the system ground, including shielding, and into the receiver front-end. How do you solve it? Shift the crystal frequency when on problematic channels. So, while the concept of a common ground which carries no signals may be an interesting one, in practice it simply does not exist. - Jack Brindle, W6FB. -Original Message- From: Ron D'Eau Claire r...@cobi.biz Sent: Apr 1, 2009 2:00 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] BL-2 Connection To An Unbalanced Wire Antenna Jim, IMX it's a mistake to equate RF ground with an Earth connection. An RF ground is just a low-impedance, low-reactance current sink for RF. Of course it is an integral part of the antenna circuit. An RF ground would not be expected to radiate, and most counterpoise or radial setups don't radiate a significant amount of energy*: 1) Counterpoises near the Earth and on-ground radials tend to couple all their energy into the lossy dielectric of the Earth, never to be seen again. This is how BCB stations achieve a good RF ground generally using 120 0.2 wavelength radials around their towers to couple the RF into the Earth. 2) Elevated radials will radiate a lot unless they are carefully balanced and symmetrical so legs produce RF fields that cancel each other outside of the immediate area of the antenna. Such radials, like any RF ground, *are* part of the antenna circuit but, when properly designed, they are a non-radiating current sink. In the common ground plane designs, they also decouple the radiating element from the feed line, providing an RF ground not only for the radiator but also grounding the feed line at the antenna so RF currents don't flow down the outside of the coax shield. Ron AC7AC * Students have asked me what happens if they use only one radial with a 1/4 wave antenna. I reply that if they make it 1/4 wave long, then elevate them both into the air and arrange them to run in opposite directions for maximum efficiency, one 'radial' works just fine. If they draw out the antenna I described on paper they'll recognize the common center fed dipole antenna. In that case, there's no problem with the radial radiating. -Original Message- On Tue, 31 Mar 2009 18:43:39 -0700, Ron D'Eau Claire wrote: But it *IS* a ground for RF purposes Nope!

A connection to earth does NOT do any of those things. It IS critical for lightning protection. That's all. Radials are not GROUND in any sense. They are part of the antenna! Indeed, their purpose is to intercept the fields produced by the antenna and by providing a low resistance path for return currents, prevent those fields from producing current in the lossy earth.

Re: [Elecraft] hot glue K2 toroids?
I doubt you use actual RTV but a RTV-like sealant. RTV contains acetic acid and will eat/corrode electronics and is a no-no for mil hardware. In mil spec hardware I doubt you are winding your own toroids. While it was common practice to do your own air wound coil knifing, the CMMI people have pretty much axed that practice as it makes it too easy to loose the recipe and manufacturing costs are too high. Now everything is bought with a ridiculous tolerance spec from coilcraft or its laser trimmed.

Since building switchers for the military is my profession these days i would like to think i have some authority on the subject. Failures can occur almost anywhere in a switcher and the most typical type depends on the topology of the supply. Typically there is a pass transistor on the input that will turn off power to the whole supply (at least in my designs) if anything goes out of spec however i would bet in cheap commercial supplies this is not always the case. My most common failure in lab tests for me is the primary side transistor, what happens depends on whether the transistor fails short or open. If it fails open you typically have no voltage on the output (again this is dependent on topology) but if it fails closed, you can get runaway on the output in certain topologies. I would like to think any 'smart' design has a pass transistor and enough bit and supervision circuitry as to shut the supply down if something goes wrong, Component failure in the feedback loop is going to be rare, as these are typically passive components, either a resistive divider, a sense winding on the transformer, these parts typically don't fail, and if they do, they fail in spectacular fashion which usually gives you a clue something is going wrong.

Re: [Elecraft] smaller?
smaller is also better for RF, surface mount resistors and caps are much more consistent to manufacture and better for RF due to almost eliminated stray effects. Also with cheaper comes more accurate, almost all surface mount resistors are 1% and they are cheaper than the 5% ones.

Re: [Elecraft] New Elecraft rigs...
It seems to me the old guys want things to get bigger, i want them smaller, there is no reason with advances in technology and smaller components that you cant fit a radio with the performance of the k2 (basic anyway) into an altoids tin, look at the AT-Sprint i think its a great example of what can be done. If you want a better example i spent the summer building and prototyping a power supply for military radios, we shoved 350 watts with 9 outputs and red/black isolation into a 3U conduction cooled compact pci card, which with the height restriction that imposes i think was a pretty amazing feat. If i had the free time to actually study the k2 and figure it out on the level that don has it down, i wouldn't mind designing my own, but alas i never have enough time to finish any of my dream projects, only to start them and then to leave a bunch of parts and sketches in a box somewhere.

It would likely be a rig I would really like, as there are plenty of small rigs out there. They don't need to go head to head with the major manufacturers if they don't want to, they can sell what they sell and how they want to sell it, and be as big or as little as they want. My guess is they want to sell zillions of K3's though, with all the jetting around to hamfests. If the K4 was twice the size of the K3, and had four times the knobs and buttons on it, and had the K3 performance, I bet they would sell even more of them then K3's, at a higher price. I don't see why Elecraft could not get very large in short order, as no one has the range and performance they do, kits, small rigs, top end performing rigs, medium size rigs, backpack rigs, antenna tuners, amplifiers, and with the K4, big deluxe rigs.

Re: [Elecraft] New Elecraft rigs...
I think we need to get with the times, i'm not saying a smaller box for the k2, but i wouldnt mind seeing a surface mount version, which would mean more space inside the box for user mods and tinkering, i think with all the options installed everyone agrees the k2 is a tight fit. And as much as everyone seems scared of smt, it seems to be the same fear of toroids, there not that bad, theres nothing hard about it, no magic spells to cast, it just takes a little practice, so the sooner we get a kit radio we really really want, that requires us to do a little surface mounting the sooner the ham community will get over itself (this is the 20 year year olds perspective though) Matt KD8DAO On 9/6/07, Brett gazdzinski [EMAIL PROTECTED] wrote: I don't know if people want it smaller, or they push smaller stuff to the people, or if it's a young thing, or what.

Re: [Elecraft] solder in kits, the sequel
In response to the solder comments i'd like to contribute my $0.02 : IDM, As long as the solder is not on the prohibited list it doesn't matter. There I said it, everyone proceed to gasp and freak out. I'm still working on my K2 slowly, and have now used more than 6 different kinds of solder ranging from kester, to radio shack, to multicore. I've used various diameters from way to small to way to big. I don't think it really matters, any solder that melts will produce a radio in the end, you could spend a lifetime arguing about which is better and perfecting your special solder formula, I would prefer to get a few QSO's in instead. I will admit that a good solder is nice and minimizes the effort and fuss, but even crappy radio shack solder (from my testing it has been the worst so far) works though it requires added cursing and a few rude gestures to make it cooperate. Solder is solder despite what everyone likes to claim IMHO, and a little practice and a decent soldering iron is worth more that worrying about what brand/mix solder you are using. Just pick up the soldering iron and get to work, your gonna make a mistake or two, your going to need some practice, your going to need to let the smoke out of a few things in the process. In the end, mental energy and effort is better spent in actual building and use of the project than freaking out because you don't have the magic bullet special solder.

Also does anyone know the gold plating thickness on the right angle connectors? I am generally unhappy with the wetting I am getting on several pins and am concerned about these solder joints breaking somewhere in the future, has anyone else had this problem (Before I get the canned responses I am using a Metcal RF soldering iron with a 037 tip and am building the board in compliance with JSTD 001D Class 3) Thanks a bunch.

[Elecraft] RE: Started building my K2 have a few ?
A metcal 037 tip is 700 deg F. I'm using some kester 60/40 solder I had laying about(pocketpak), not sure of actual part number. In regards to my plating question, from a commercial production standpoint, if gold plating is too thick on a part, it tends to cause cracking in a solder joint in later life. Under JSTD001 gold platings above a certain thickness are supposed to be filed/sanded down to alleviate this problem. Usually at least in my place of business we do not know of problems with plating until it is too late. I was just curious if there were any other 'crafters out there that have had issues with the gold plated connectors, if not I don't plan on worrying about it, I have not had the opportunity to look at the joints under a scope, however just the fact that capillary action failed to pull solder thru the vias and wet the top of the board gave me a bad initial feeling ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
