I have seen it done once about 25 years ago for a repair shop I was installing but I couldn't describe the procedure off the top of my head. I remember they made periodic measurements while sinking a ground rod in the soil; they met the specified resistance after driving the rod 100 meters down! The specification required something like .001 ohm. There is a military specification or standard on the subject. Now that most military specificatations are declassified it is [probably online.

The people who do it a lot use a clamp on meter but it can be done with a meter, power supply, wire and 3 or 4 probes. I have some books that tell how here somewhere but I think the materials are available from PolyPhaser. michael N6CHV Bruce Muscolino wrote: > > Patrick, > > Ground resistance is a fairly common measurement with sensitive test > equipment.

If you get the DDS Daughtercard from NJQRP, you will be able to drive it with your PIC-EL, or as a minimum, build up a PIC to drive it. The Far Circuits board does include real estate for the PIC and LCD, which, depending on your perspective, may be good or not.

Dug out my old posting: Doing a bit of follow-up on the mystery of tying two electrolytics in series back to back for AC use. Electronic urban legend or fact? I hooked a couple of garden variety aluminum electros, 10 uF, 36V rated, in series with their negative leads tied together. Hooked 'em to a 6.5 volt AC, 60 hertz supply. BTW, that's about 500 ohms reactance total, so about 13 ma rms current flowing. Measured from the center out to each end with my DVM set on DC. What do you know? I get -1.5 VDC. Where did that come from? Cecil said electros will give some non-linear diode-like behavior. Maybe so. When I checked later, it had dropped to a volt. Then -0.35 volts and finally after 3 hours it was at -0.18 volts. Trying again with two caps from the same bag but this time tied + to +. Initial voltage is +0.9 which climbs to +1.19 VDC in a minute or so. Now after about 15 minutes, it has dropped to +0.6 VDC. So OK--not a real definitive test, but better than what I had to start with. Voltage will build up at the center. Whether it will eventually drop all the way to nothing, I don't know. It's not enough to keep the caps from being reverse polarized during part of the cycle, but it does keep the average over time biased in the right direction. 72--Nick, WA5BDU ------------------------------ Date: Fri, 16 Jan 2004 22:39:28 -0500 (Eastern Standard Time) From: "Mike WA8BXN" To: "Low Power Amateur Radio Discussion" , Subject: [165528] RE: [qrp-l] Re: non-polarized electrolytic Message-ID: <4008AE70.000001.02360@compaq1500> MIME-Version: 1.0 Content-Type: Text/Plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit I think in the very early days, long before solid state diodes, something akin to electrolytic capacitors was used for rectifiers.

How about as a stand-alone VFO, a signal generator for your bench, a replacement LO for your Sierra or NC40 transceiver, or perhaps as the heart of an antenna analyzer! Control it with your favorite microcontroller, or even hang it off your PC's printer port. Any way you do it, you'll be generating quality signals for under $20." 1) With a PIC It'll work directly with the PIC16F84A and the "siggen3" PIC DDS VFO project that started this whole craze. One can get the PIC code from the HamPIC Resource Page (http://www.njqrp.org/ham-pic/projects.htm) and program the PIC directly to control the DDS Daughtercard. Adding a rotary encoder yields a project that is a good VFO with bells 'n whistles designed by Craig AA0ZZ and Bruce AA0ED. 2) With the QuickieLab It plugs directly into the NJQRP QuickieLab (http://www.njqrp.org/quickielab/index.html) to give that BASIC experimenter's platform RF generation capability. With the canned software available for this project, along with Joe Everhart's wonderful "Quickies" and "Test Topic & More" columns that focus on its use, this is probably the easiest and most flexible way to play with a DDS. http://www.njqrp.org/dds/index.html ----- Original Message ----- From: "Steve" To: "Low Power Amateur Radio Discussion" Sent: Friday, January 16, 2004 9:31 PM Subject: Who Makes Good AD9850 Digital VFO Boards?? > I have gotten my little gruby fingers on a couple of AD9850's and I am > itching to build up a good digital vfo or signal generator.

First step is to remove the gps so the mouse will function. (took me a while to realize that had to be done) I would find out what comm port has been assigned to the gps and then see what else is also setup for that port. Two serial devices can not share a comm port.

Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII If you're looking for something neat to go with your W5JH/Az ScQRPions brass paddles, I have an answer. How about a directly attached, bolt-on memory keyer? I have built and will be selling the PicoKeyer ScQRPion Special, a 1.9" x 2" keyer designed specially for the ScQRPions paddle kit. The keyer attaches directly to your paddles using existing screws. Just unsolder your cable, remove three screws, attach the board and you're off to the races. This keyer uses the new Super PicoKeyer chip, which offers speed control using the menu and paddles method and/or a convenient pot for quick adjustments. You can set a speed via the menu, and any time the pot is set to its minimum position (below 5 WPM) the speed selected by the menu is used. Use the pot, the paddles or both. It's slick. Of course it's got all the other features you would expect - two memories with chaining and beacon mode, message pause, variable pitch sidetone that can be turned on or off, adjustable weight, A or B timing, dot & dash memories, tune / straight key mode, etc. The on board battery ought to last a good long time (I don't know exactly HOW long, since I haven't yet killed one). The kit includes all needed parts - PCB, chip, socket, battery and holder, jack, keying transistor, cap, resistor, pushbutton switch and even a rubber foot to help stabilize your paddle. My paddle (#72) no longer tends to scoot around as I use it. No permanent changes to your paddles are needed, and the keyer can be removed at any time. I wish I could say this will keep you busy with a soldering iron for a while, but I'm guessing the average builder will be done about the time the coffee starts getting cold. You could satisfy your remaining homebrewing urges by making a nice polished brass cover with your call sign engraved on it or something. I'm taking orders now. As soon as I get enough orders to make up a batch of PCBs I'll order the boards, which will take 2-3 weeks for delivery. I get 6 boards to a panel, and I'd like to order 4-5 panels at a time to save on shipping. I'll order extras, so any subsequent orders probably will not have to wait long. I just don't want to pre-order a bunch of boards without some way to gauge demand, since this is a pretty application-specific project. The easiest way to order yours is to point your browser at and order there. I'll also take checks or money orders by mail, or regular PayPal payments -- just make sure to tell me what you're ordering, who you are and where you want your kit shipped. Total cost with shipping in the US is $18.00; DX orders please email me for shipping costs. 72 & have a great weekend, Dale - n0xas -- It's a thankless job, but I've got a lot of Karma to burn off. NEW PicoKeyer version with pot AND paddle control is here!

The only Lithium battery I have is one called a B-9583 and it is made for several cameras. It is re-chargeble about 300 times. It's voltage is about 3.7 volts and it's capacity is 1050 mAh. A new one costs $20.00 from the cheapest web site and is made in China. The re-chargable Lithium battery is called it seems, a Lithium-ion battery (Li - Ion for short). A battery that cannot be recharged using Lithium is called a plain Lithium Battery. To charge a Li -Ion battery you need a special charger. These are now almost always built into the camera or ham radio. But you can build one special at home. The chips are available but are surface mount only. Sam's Club has a large section of their camera area devoted to batteries. They have a lot of Lithium and very few Li - Ion batteries. The rechargeable are only available if you also buy a charger.

I can't see all those pins . . . My, iron is too large . . . My first time . . . Sound failure? Not to worry about damage to that new DDS chip. I just built two DDS 9850 circuits and both work using the 'gob'solder-on/wick-up technique (below). Want a warm fuzzy? I am 63 with trifocals and can not see those tiny pins ! ! How may DDS circuits have I built in the last few weeks? TWO How many worked the first time? None *BUT* >>>NOT due to SOLDER PROBLEMS. The problem was, first my compiler then my programing skills. I use silver bearing solder with a low temperature iron. First, the PCB must be 'tined (a lite coat of solder already on the pads), but most PCBs come already tined, just wipe pads bright with a paper towel. Second, tack solder two opposite SMD pins to hold the chip in place on the PCB (not to worry about shorts and bridges >my first accident<). Third, tack the other pins down, again here too, not to worry about solder shorts or bridges between pins. Next, with very thin light weight solder-wick (braid embedded with flux), place braid between iron and one side of the SMD to reheat all 14 pins at same time and wick up all that will come, let cool, then do the other side. I must use a magnifier to inspect work in case touch up is necessary, to date none required.

So long as it 'sounds' ok? I say any rig sounds as it looks...fixed delay in the 'sending station's' rig is one thing...I can detect that only by viewing the waveforms...varying delay, whole 'nother story... For my own sending, there's how it 'sounds' in my rig's sidetone and then there's how it 'sounds' in a properly adjusted separate local receiver... Anyway... I'd like to know what you guys think about the ARRL's conditions under which a rig-under-review is tested for "CW keying waveform", particularly regarding the "equivalent keying speed is 60 WPM" spec. Granted, all rigs should be tested under equal conditions, but 60 WPM?...how 'bout 6 WPM with a scope sweep speed of 100 milliseconds per division... Ok, perhaps that'd be swinging to the opposite extreme. Umm...15 WPM with scope sweep speed of 40 mS per (using variable sweep, of course), maybe? I know, some other digital modes are affected by a rig's 'QSK' abilities (especially,a rig's receiver recovery time) but I'm only interested in discussing CW for the immediate, including that receiver recovery time( the other half of QSK)... And, what about using 14.2 MHz for Hf rigs in CW mode...right, it really doesn't matter, technically...14.2 MHz or 14.06 MHz etc... What do y'all say? 73.

Wal-Mart sells the Lithiumion batteries in their camera department. They are used in Sony digital cameras and several different brands of camcorders. They are not cheap, they run about $60.00 each. They work very well and have a long life between charges. In my old Sony Digital you could take up to 500 photos (about 250 using flash) before having to recharge.

If you are having problems getting your band modules to seat properly you might need to physically realign the band module slot. You will need to do this if .... A) You can't get your band modules to fit flush in the slot. (Note you should ensure that this is a problem with multiple modules. If there is only a problem with a single module then you should check the connectors on that module to make sure the problem isn't due to bent connectors on the module.) B) You find that it seems to require a little too much force to get the modules in. Again it should be an issue with multiple (ie all of them) modules not just one or two. The procedure to correct this is simple. Remove the 2 black screws on each side of the rig. This will allow you to remove both top and bottom covers. While holding the rig with the front panel facing you, note the two stacked silver colored screws on the left side of the rig at the rear left of the band module slot. If you look closely you can see that these screws are attached to the small PCB at the back of the band module slot via a small L-bracket. By loosening these screws slightly you can make minor changes to the orientation of the PCB containing the band module connectors. I found it to be a bit of trial and error. When you have things aligned correctly you should be able to insert the modules so that they are fully seated (ie flush with the face of the rig) with a minimum of force. Once you have done this verify that all your modules fit fine and rig is working ok with each module inserted. If the alignment gets too bad and you don't correct it you are likely to either damage the band modules or the slot itself either by bending the connectors or causing excessive wear to the contacts.

The only way it *would* make sense is if the keying were perfect at that speed. Then I'd know it would also be fine at lower speeds. But if it's not fine at 60 WPM, what have I learned? Is it OK at 40 WPM? I'd suspect that fewer than 1% of CW ops carry on QSOs at 60 WPM, even allowing that a few more than that can copy that speed. Now to the specific test of the K2 at 100 watts: The O'scope trace is pretty weird, alright. [New QST, page 79] You assume that the upper inflection of the keying waveform is 'key-down', but then how did the rig know that a second dit was coming, as you pointed out. So maybe the lower part of the trace means key down. The time between dits is a little less than the key-up time of 20 ms. I guess the rig stretches time a little to avoid shortening and it's overdone a little. Still, for 60 WPM, that trace looks pretty good to me. 72--Nick, WA5BDU -----Original Message----- From: owner-qrp-l@Lehigh.EDU [mailto:owner-qrp-l@Lehigh.EDU] On Behalf Of bill@n4qa.com Sent: Saturday, January 17, 2004 9:30 AM To: Low Power Amateur Radio Discussion Subject: [qrp-l] ARRL rig reviews QSK test...

As I think someone mentioned, this only seems to be stressing the capabilities of the radio. However, I would like to see the waveform at other speeds, too. Even when contesting, I rarely go much above 30 wpm. If I start going too fast, I seem to get a lot fewer answers! The other thing I would like to see them include is tests for key clicks. Very few radios today seem to have the rise and fall times designed appropriately to prevent key clicks. Unfortunately, even the K2 is guilty in this regard, particularly the fall time. According to W8JI's web site (http://www.w8ji.com/what_causes_clicks.htm), the ARRL recommended rise and fall times should be about 5 ms. The ARRL review of the K2/100 seems to show a fall time of 2 ms or less, and the rise time isn't much better. Having said that, I'm sure Eric knows about this and will have a fix in the works at some point in time. 72/73, ____ / _____ / / ) / / / /____/ ____ /___ (____ ____ /___ /___ / ) / ) / ) ) / / ) / /_____/ /____/ /____/ _____/ (____ / / / . . . +----------------------------------------------+ | Bob Schreibmaier K3PH | E-mail: k3ph@ptd.net | | Kresgeville, PA 18333 | http://www.dxis.org | +----------------------------------------------+ ------------------------------ Date: Sat, 17 Jan 2004 11:56:59 -0800 From: "Lee Hopper" To: "Posting to the list QRP-L" Subject: [165585] Fw: [SOC] Ever tried CWCom?

The object of the diode it to conduct if you connect the power in the wrong direction, clamping the voltage to 0.7 Volts and blowing the fuse. If you are going to protect the equipment, you need the diode to have a forward current which is higher than the fuse, otherwise the fuse will not blow, but the diode will, letting the negative voltage into the equipment to reap havoc. I also would not consider putting two 1N4001 diodes in parallel as if one has a slightly lower forward resistance, it will blow first and then the second one will go. You need to search out a diode with a forward current of at least 2Amps and I would recommend 5Amps for safety. 72/73 Ray, G4FON ------------------------------ Date: Sat, 17 Jan 2004 14:51:26 -0600 From: "Jim Sheldon" To: "Flying Pigs Mailing List" , "QRP-L Mailing List" Cc: Subject: [165593] First Hellschreiber QSO with the Modified PSK-20 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit After modifying the PSK-20 to work pretty much all modes, I set making at least one QSO per mode.

Message-ID: <001601c3dd3f$cff03550$0400000a@wa5bdu> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit There are a couple of ways to use the protection diode. One is to put it in series with the positive line so it blocks reverse polarity. The advantage is that no fuse has to blow or anything when you hook it up backwards. The disadvantage is that you lose "one diode" drop of voltage to the rig--meaning about 0.7 volts, in normal service. This may not be critical if you use a 13.8 volt supply or an adjustable one you can crank up. It is more critical if you use a battery and you want to get all you can out of it. For the series diode method, many folks use shottky diodes, because they drop less voltage in conduction. Maybe 0.4 volts instead of 0.7. The 1N4001 is probably OK. It's a one amp diode, which is probably all that rig pulls on transmit, more or less. A two amp would give a little margin though. I think it's a 50 PIV, so it should be able to block 12 V OK. The other method is to put a fuse in line and put the diode in reverse biased to ground, downstream of the fuse. Advantage is that there's no voltage drop in normal service. Disadvantage is that you blow a fuse and draw a spike of current when you hook things up backwards. Also, there will be some brief reverse voltage on the rig for the time it takes the fuse to blow, but it won't be a full -12 volts. With this method, you need to be sure your power supply isn't current limited at a value less than (or close to ) the fuse value, or it may take a long time to blow the fuse. Or it won't blow at all. Still another method is to use a full wave diode bridge at the input. Hook the DC where the AC input normally goes. This is foolproof and there is no such thing as backwards. Disadvantage is that now you lose TWO diode drops of voltage drop. ************ On troubleshooting (the HW-8), look your schematic over. Hopefully, the transmit circuits did not become energized and so weren't harmed. Look at components (polarity sensitive ones) that have little or no resistance to the supply line as more susceptible than those with big resistors limiting current. Electrolytics directly across the line are highly suspect. If you can energize the rig, see if transistors that should be active have 0.5 to 0.7 volts from base to emitter. Heath is good about putting voltage values on the schematic. Check them out.

The TSSOPs like the AD9850 have their legs a lot closer together and are a real pain without a decent board. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Stephen Wandling" To: "Low Power Amateur Radio Discussion" Sent: Saturday, January 17, 2004 4:20 PM Subject: Re: Who Makes Good AD9850 Digital VFO Boards?? > My vision of Dennis' idea would look like Fig 3 or 4 of the 9000 series, > but without the outer ring of pads.

I am doing an article for QRP ARCI Quarterly about the subject now. A quick summary would be: Headphones: used to be 1/4" now mostly 3.5mm, likely stereo, connectors. You can find 2.5mm, but that mm makes a serious difference in mechanical strength. Mouser does have a really neat little 2.5mm plug though you'll find not much to plug it into besides what you build. Unless you seriously need the space, use the 3.5's. Keys: mixed... probably more 1/4" for transmitters/transceivers w/o built-in keyers but 3.5mm for the rest. Stereo connectors for paddles. (Audio) Line Out: RCA jacks. I use these for almost any audio, single line, output. The "Line Out" thing is the 500 ohm output for RTTY, etc. Power Input: 1) 'Low" Power: 2.1 and 2.5mm (called "coaxial") DC Power Connectors. I settled on 2.5mm, with the center positive. These connectors are working TOO hard at 3A; 2) Molex connectors, many kinds, work well, die easily; 3) Anderson Powerpole connectors... THE connector of choice for anything under 175A (Yes... 175A.) RF: Your preference... most common QRP connector is BNC. Internal cable interconnects: SMA and SMB. All-Weather multi-pin: For these you have to just pour through the Mouser and Digikey catalogs. Expect to pay some serious bucks, and only buy gold pins. 72/73 Ed Tanton N4XY Ed Tanton N4XY 189 Pioneer Trail Marietta, GA 30068-3466 website: http://www.n4xy.com All emails & checked by Norton AntiVirus with AutoProtect LM: ARRL QCWA AMSAT & INDEXA; SEDXC NCDXA GACW QRP-ARCI OK-QRP QRP-L #758 K2 (FT) #00057 -------------------------------------------------- "He that gives up a little liberty to gain temporary security will lose both and deserve neither". --Benjamin Franklin "Suppose you were an idiot ... and suppose you were a member of Congress... but I repeat myself." --Mark Twain -------------------------------------------------- ------------------------------ Date: Sat, 17 Jan 2004 18:26:50 -0500 From: Ed Tanton To: , QRP-L Subject: [165610] Re: Fwd: R: Antenna Analyzer Message-ID: <6.0.1.1.2.20040117182540.01fa08c0@pop.earthlink.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed From moments ago experience, 145 euros through paypal is $185. 72/73 Ed Tanton N4XY Ed Tanton N4XY 189 Pioneer Trail Marietta, GA 30068-3466 website: http://www.n4xy.com All emails & checked by Norton AntiVirus with AutoProtect LM: ARRL QCWA AMSAT & INDEXA; SEDXC NCDXA GACW QRP-ARCI OK-QRP QRP-L #758 K2 (FT) #00057 -------------------------------------------------- "He that gives up a little liberty to gain temporary security will lose both and deserve neither". --Benjamin Franklin "Suppose you were an idiot ... and suppose you were a member of Congress... but I repeat myself." --Mark Twain -------------------------------------------------- ------------------------------ Date: Sat, 17 Jan 2004 23:31:56 +0000 From: M Taylor To: n2go@arrl.net Cc: Low Power Amateur Radio Discussion Subject: [165611] Re: Fwd: R: Antenna Analyzer Message-ID: <20040117233156.A13126@pull.privacy.nb.ca> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline On Sat, Jan 17, 2004 at 05:32:25PM -0500, n2go@arrl.net wrote: > Hi, > Is the Euro on par with the Dollar yet or did it pass it? http://www.xe.com/ For all your currency exchange queries (and I believe they provide various exchange service as well).

Message-ID: <4009C73D.C3EE2E2D@KN5L.net> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit It has been my assumption that the oscilloscope sweep rate is selected first to resolve and measure the slope of the leading and falling edge of the CW key waveform. Then a CW speed is selected which will show a few key transitions within the display. Assume that the rising and falling edge shapes will remain essentially constant for varying CW speeds. A slower sweep rate for a lower CW speed will indicate vertical, or almost vertical leading and falling edge waveforms.

The image under discussion (QST February, 2004, page 79, figure 7) shows a single-sweep of a dual-channel scope, having a common time-base. If you're suggesting that false 'scope triggering caused the apparent timing relationship depicted, I respectfully disagree. In Bill's world, the following is happening in figure 7: At T0, first-dit key-down (upper trace) occurs at the extreme-left-hand side of the blue shaded area (the 'scope' screen). This is the start of the single-sweep. At T1(~ 20 mS after T0), first-dit key-up occurs. At T2(~ 22 mS after T0), first-dit RF envelope begins(lower trace). At T3(~ 40 mS after T0), second-dit key-down occurs. At T4(~ 42 mS after T0), first-dit RF envelope concludes. At T5(~ 56 mS after T0), second-dit RF envelope begins. At T6(~ 61 mS after T0), second-dit key-up occurs. At T7(~ 72 mS after T0), second-dit RF envelope concludes. At T8(~ 80 mS after T0), single-sweep ends. For the first-dit, the RF envelope lags its 'key-down' by about 20 mS, or a phase-shift of ~ 180 degrees. For the second-dit, the RF envelope lags its 'key-down by about 16 mS, or a phase-shift of ~ 140 degrees. If I were able to do 60 WPM(I am not), this timing relationship might be somewhat confusing...especially if listening to my own sending through the use of a properly adjusted separate local receiver as opposed to listening to my own sending via a contrived 'sidetone'. Whew! There's a lot to this thing we call CW! 73.
