Message-ID: <3FC8B057.96509F0F@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Well said Bruce, a typical small company commercial telling us the likes of a NASCAR team is as good as GM/Delphi. I do not doubt that your company makes excellent products, maybe 10 or 20 at a time, and that your customers are satisfied. But what would you do, and what changes in assembly and testing would you make if the contract called for 100 or 1000 units? Sure, wave soldering is a dated technique, so am I. Wave soldering was the best and most reliable technique available when I was working. ALL components were through hole types. Our boards were four layer double sided, about 8* x 10" with about 100 to 150 components on them. The circuitry was a mixture of analog and some digital. Wave soldering gave us the best consistency. Is consistency important to the customer as long as the unit works properly? Yes, especially where you don't repair any failures. I know, your equipment does not fail) , but in the real world of production equipment does fail, and the military and other high volume users like Panasonic and even ham radio companies have learned that in-house or INDEPENDENT repair depots are the best way to care for their products. To have success with such a concept requires not only careful training of personnel but a highly consistent product build. It is not enough to slap o the lid and say "it works". You have to prepare specs and write service and operating manuals, but you have to ensure that serial number 1001 is as exactly the same as serial number 1, to the best of your ability. Also you must ensure that the boards in serial number 1001 and serial number 1 will interchange any spare boards you provide and that they will work as designed. Specs and standards are very important in this effort. They provide the outline that ensures that all the units look and perform exactly the same way With individual, low volume production the only way to guarantee such a result is to have a single operator or team build the run. I am sorry you think standards are generally worthless. If you worked in a real production environment you might have a different idea. And large production companies are mot all slow moving slugs either. The company I most identify had less than 300 employees when we won the contract for the F-16 Flight Control System. This was a multi stage production contract, where we built about 20 pre production prototypes. These were the equivalent to your small hand built production runs. Our design was entered in a "fly off" against several other autopilot vendors; we won and received a production contract for about 100 airplanes. Our success with these led to more contracts for more planes. At every point we had to conform to both government specs and standards but aircraft manufacturer specs and standards and our own internal specs and standards. These ensured commonality of units from number 1 on. Don't get me wring here. I love development. I made my living at it for a long time. When I became associated with aircraft flight controls my career direction changed to production support and then to field engineering and support. Here is where commonality became sort of king. It didn't matter what serial number it was, you had to repair it. And we had one directed sub-contract for certain boards in our box; they had to be repaired and tested in one shop! I n the end this discussion really comes down to a matter of perspective. If you have always worked for a small company you will view it one way. If you have only worked for large production companies you will view the problem in a different way. Perhaps I am fortunate, I have worked for both and can understand both sides. That is what I am asking of you by these posts.

Yes that is a valid assumption since you can measure or compute what is at the input and the output. But you don't know the length of the transmission line.

I find it extraordinary that companies can produce consistent results over thousands and perhaps millions of identical products. And the methods we use at my place of employment are not always the best approach. Sometimes we design stuff that is almost impossible to build--and we have had our share of failures where we have gone beyond that. Our Japanese customers sometimes get very frustrated with us because our methods are difficult to document. Our entertainment industry customers are mean and nasty and sue happy--that's how that industry operates. Our military and government customers sometimes disapprove of our methods (but they come back for more. So, we must be doing something right)...still, there are often better approaches than the ones we use. And there is the accountability thing. If someone makes a mistake EVERYONE knows about it. Small company environments can be suprisingly brutal. So, now you have "the rest of the story"...I am glad we could discuss this civilly--sometimes I get wound up and forget to be a gentleman.

Regarding the lacquer, I use a type available from McMaster-Carr (www.mcmaster.com>. Use their search engine and look for clear lacquer. This product is pricey but in my experience it is tough, invisible, and last for years without crazing or delaminating. (No financial interest, etc.) Regarding the scarcity and expense of springs. It is true that it is hard to get compression springs of the desired characteristics, but it seems that tension springs are much more common and cheaper. If you buy a bag of assorted springs the bulk of them are likely to be tension springs. They can be easily converted by "overextending" them until they are deformed to the required degree. The coils will now be evenly separated, and you will have a compression spring. By changing the amount of overextension, you can set the stiffness of the resulting springs over a very wide range. Then clip out the length you need, and bend the last turns inward slightly to form a flat end surface. You can make a large numnber of such springs for very little cost. Also, McMaster-Carr, as mentioned above, has long length of compression spring material that can be cut to length. The AZ paddles look very nice, and all the work that the club is putting into them will be much appreciated by QRP enthusiasts. An excellent club project. 72, Rich, WB9LPU ------------------------------ Date: Sat, 29 Nov 2003 10:05:27 -0800 From: "Michael Melland, W9WIS" To: , , Subject: [162048] FS: S&S Engineering ARK-4 40 meter Transceiver Message-ID: <003001c3b6a3$607c7700$0300a8c0@e5o8v5> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit S&S Engineering ARK-4 40 meter QRP rig.

Altoids has a couple of new collectible tins, my favorite being Curious George. There is also a shaggy creature tin from a 'toon that I don't recognize. The Curious George tin would make a fine "salesman's sample" where you pack a neat QRP rig into the tin in order to spread the gospel to the uniniatiated. 2.) Wallyworld has a very clean round tin collection in the kitchen gadget department. Nice rounded edge circular tins for spices. CHEAP and easy to customize as the stickers are eazy-off. I've seen the same types of tins at Micheals Crafts and/or A.C.Moore. 3.) Michaels has in their current flyer, the small wooden boxes that are great for that custom "Louisiana Look" epitomized by the fine work of Jim N5IB. Check out his website. I saw that A.C.Moore was also 'giving' these small boxes away and they had a nice variety. 4.) Home Depot (my favorite store & also the store my 5 yo daughter has grown to hate the most) has in their Turkeyday sale, small Sheffield knife gift sets that come in a GREAT little carrying case.

But in today's market the demand for analog meters is low, so buying a good quality meter movement, scale, and mounting bezel is becoming quite expensive (even low quality ones are no bargain). So the new designs are using DVM displays--partly for the more modern look, partly for the improved resolution, but also because it costs less. (2) There are several common sizes, but all are much larger than 7/8". Some use rectangular holes instead of round--that makes accurate hand cutting a bit easier. Using a behind-the-panel mounting gives a good look with a rectangular hole (like the meter on the HW8, HW9, etc.) (3) To make the large hole, the best hand tool is a Greenlee punch. But if you think the meters are expensive, wait till you see the price on a 2" punch! I go with scribing the circle, using the nibbler to come close to the scribed line, and carefully filing out the last fraction of an inch. It need not be perfect, as the meter front will cover up small imperfections in the hole. It's a trade off of time for money: Like most QRPers, I'm willing to spend more of the former than the latter. (4) Many common DVM chips provide a read-out as a ratio to a "reference voltage". The reference usually is a fixed voltage at 100mV, 1V, 5V, etc.--but if you apply a variable reference, the meter displays the voltage ratio. This includes the Intersil 7106/7107 family, the National 3914 and 3915, and even the ADC input on some Microchip PICs. The PIC option is intriguing, because you could use software to linearize the display. 72, --Tim (KR0U) >"Jason Hsu" : > ><...> > >My questions: >1.

Is the hex file on the ARRL web site the same as > the code shipped with the chip from you? Inquiring minds just gotta know. Nope. The hex file on the ARRL site is the code as it was at the time the article was written, which was April of this year. I had to freeze it at some point, and didn't want the hex file to be too far out of sync with the article text. I added some features in July and August that are not in the older version. Here's a list of differences: 1.) Beacon mode. The code available from ARRL uses a jumper or switch on pin 4 for beacon mode. The newer versions use an embedded BN prosign and don't require the jumper (pin 4 is unused). I find that much more useful for sending CQ; I set mine up to beacon a 3x3 CQ every 10 seconds, and if someone responds all I have to do it tap a paddle to shut off the beacon. 2.) Message pause. The PS prosign is not supported in the old version. 3.) Straight key mode. The newer version supports the use of a straight key, detected at power on. Anyone ordering a pre-programmed chip, regardless of whether it's from the reference in teh article or not, will get the latest version. It's still backwards compatible with the old version and is sent with the latest instructions and data sheet, so even if they have built a board with a jumper for beacon mode it will still work fine. > dit dit es good job, Thanks! 72, Dale - N0XAS -- It's a thankless job, but I've got a lot of Karma to burn off.

I was thinking of using a BNC T connector, with one end on the Ant. terminal of the K2, dummy load to the other end and the tap would go the the scope. Should I connect it directly to the scope with a short length of coax or use the scope probe. (which is compensated for a nice square wave.)? What is the correct way to trigger the scope. Should it be tied to the Keying line or let the scope autotrigger on the rigs output? If you should use the key line, what is the easiest way to do it if the rig has a built in keyer?

There is one described in EMRFD (Experimental Methods for RF Design). It is actually for testing AGC (dits a bunch of RF into the front end of the radio), but can be easily adapted to dit a keyer instead. The circuit used by the ARRL Lab is described in the "ARRL Test Procedures Manual" (http://www.arrl.org/members-only/prodrev/testproc.pdf) as a "Keying Generator" on page 133.

It's got temperature, diode and transistor checking along with the V-O-M functions and seems to be very precise. It has a nice removable rubber "padding" that holds the electrodes and doubles as a stand, along with protecting it when it gets pulled off the bench....

Keith here in the Depths of the Great Bergen Swamp Well, with further Googling not finding anything short of custom envelopes available in 10K+ quantities, and NEEDING two envelopes NOW, i went the homebrew path. I disassembled and measured a 12 cm CD envelope and scaled it accordingly for the 8 cm envelope. It ended up that I could fit both envelopes on one 8.5" x 11' sheet. I ended up with about 1/2" of scrap on each long edge and 3/4" of scrap on the short edge, not bad. My wife was looking over my shoulder and commented that if these were so important that maybe, just maybe there is a market for such an envelope. That brought the secondary though on my part that maybe someone has software to lay out custom envelopes. Then a vendor to make envelopes, package them in 50's and 100's and take them to computer shows and... Man! That sound like real work! Anyway, I now have my envelopes, homebrewed in the finest of amateur tradition. Yes, I glued the edge with Elmer's Glitter Glue, but that's all that was available in the leftover day care bin... Do they still make mucilage bottles with the rubber applicator? I need some more envelopes :-) 73, Keith, WB2VUO, Trustee of the NQ2RP/B 10-Meter Beacon 28.2873 MHz on Your Radio Dial - 24/7 ------------------------------ Date: Sun, 30 Nov 2003 09:40:03 -0500 From: Bruce Muscolino To: wkhibbert@frontiernet.net Cc: Low Power Amateur Radio Discussion Subject: [162071] Re: OT: Envelopes for 8 cm (Small) CD/R's Message-ID: <3FCA0143.5C62CA38@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I would ask the stores to check with their envelope suppliers.

The manual is version OA copyright 2000. This was part of the group buy via NJ qrp club (thank you). Will check the archive for tips and stuff. What I need is page 25 of the manual, it is blank (so is page 20 but that is for 20m). Page 25 covers I think coils, chokes and toroids (# windings). Can anyone help with this page? Also missing is two caps but have those in spare parts bin. Manual seems to have errors and really wish the schematic listed values for 40m instead of * (I know it's in the band specific listings). Operating is done mostly in the woods using a endfeed half wave wire. Code speed only 10wpm and very lid like, but I'll keep improving. ;) Brian R.

The manual is at least as big, and resembles the manual for the Yaesu FT-817 in layout and in the fact that basic functions are set using a menu. As you might recall when the 817 came out one person was selling a book that took data from the 817 manual and made it easier to read and understand and such an aid would be useful for this radio. What I am happy about is the 1.5 watts output on 2 meters and 1 watt on 70 Cm's and the short antenna hits most of the repeaters in town. This is different from the other tiny radios. There is 1000 memory slots and they can store unusual splits, ctcss data and much else. You can group them any way you want for scanning. There is scanning of the whole band(s), of the memory and what parts of each! This is a huge capability since it will scan from 500 KHz to 999 MHz! Or less if you set it up. It has a good tiny computer and a big as possible lcd display window. I have no trouble reading it with my 68 year old eyes. It weighs 8 Oz with the battery so it's easy to carry in a pocket. A guy from this list found a battery place on the web that sells batteries for this radio at $20.00. This is half the price Yaesu charges. The battery will take about 300 charges, so it's good for a year of daily use. It will take several hours to set up this radio to my satisfaction. It is very complex but once you get the idea in your head on how to do most things it becomes easy. But this will take several days because I have other things to do. -- - Karl Larsen k5di Las Cruces,NM Az ScQRPions - ------------------------------ Date: Sun, 30 Nov 2003 09:41:49 -0700 (MST) From: Karl Larsen To: Chuck Adams Cc: Low Power Amateur Radio Discussion Subject: [162078] Re: [AZpad] While waiting for the paddle Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII On Sat, 29 Nov 2003, Chuck Adams wrote: > At 12:47 AM 11/29/2003 -0600, Dale Botkin wrote: > >...snip snip... > >I have some small experience with (ahem) the keyer in question, and I can > >tell you with some degree of confidence that the first thing that's > >getting done when *my* paddle kit arrives is to figure out a > >directly-attached keyer to screw onto it.

I just use a keyer, set the speed fairly high and hold the dot paddle closed. You then need to find a place in the rig to trigger the scope when the rig is keyed (easy if you use an external keyer, just trigger on the keyer output) You need to trigger the scope so you can get a stable display of the output on the scope to measure the rise and fall time and will also show you if there is any delay beween the keying and the actual RF output. If you don't have a convenent place to clip a scope probe to the RF output, using a "T" and a jumper back to the scope will work. 72, Steve, KD1JV "Melt Solder" White Mountains of New Hampshire http://www.qsl.net/kd1jv/ ------------------------------ Date: Sun, 30 Nov 2003 11:21:15 -0800 (PST) From: Mark Hogan To: Low Power Amateur Radio Discussion Subject: [162090] RE: NORCAL cap kit???

The most notable exception being SOME silver mica caps, where 330 equals 330pf. USUALLY, if there's a J, or a K, following the 3 numerals, it means the 1st definition. But it's ALWAYS best to measure unknown origin silver micas. 1000pf = 1nF = 0.001uF = 102J AND for most MIL / ceramic / monolithic caps, you can keep track by picking a standard, and equate from there. A company I worked for a long time ago used mostly 0.1 uF caps for digital bypassing, so I used 104... e.g. CK05BX104's. 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: Sun, 30 Nov 2003 15:19:55 -0500 From: Ed Tanton To: wa2dgd@comcast.net, qrp-L Reflector Subject: [162092] Re: How to measure keyed waveform Message-ID: <6.0.0.22.2.20031130111642.01d302f8@pop.earthlink.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed While I think you COULD do a direct connection-at 5W to a DL-I wouldn't do it. Use a 10X probe. That way, any loading effects by the scope input as well as those of the cable, will be negligible (*1) for HF measurements. Use a BNC-Tee. TEK used to have a red plastic pickoff (to connect the probe to the BNC CAL-OUT) that would be VERY handy for this... and connect the probe's GND clip wherever is handy. The 'regular' AUTO trigger ought to be fine-although, if you want to use a delayed sweep you MAY need to help the trigger out some with EXT Sweep. Easiest way for that is to use a 10X probe connected to the same place. I personally would use the internal, auto-trigger (which requires NO connection on its own); but if that was not working out, then the RF for a trigger; and lastly the keyer. You can use a 1X probe for the key. The trigger probe does not HAVE to be another scope probe. It's just easier to use/etc. Any BNC cable with some clips on one end would work (*2). But I think the regular Internal Trigger will be fine. Should you want to use the keying line, I see no reason the trigger probe could not be connected across the key. There's SOME voltage present on those terminals, and the CHANGE in that voltage (to GROUND/zero volts) is what will set off the trigger. (*1) Besides the input circuitry's net capacitance, a regular cable has some as well. As you know, RG-58 has a specific capacitance/foot, and that gets added in as well. Keep in mind that whatever capacitance we're talking about gets added in parallel to ground. In the case of RG-58 this figure is 29.6pf/ft. 10X probes have some pf/ft also, but the 10X divider is in the probe, reducing the effects of that capacitance on the test-subject. For RF frequencies, TEK made 2 Active FET Probes (one good to 650MHz and one to [I think] 950MHz) that placed FET amplifiers in the probe to buffer the input and reduce loading at RF frequencies. 100 pf to ground is bad enough at 7 MHz, but is DROP-DEAD-SERIOUS at 400MHz. Mostly the active probes are trying to eliminate the effects of the 10X divider capacitance/etc. rather than the cable's characteristics. Note also, that for a keying waveform, you are mostly looking for the high speed, switching-transient garbage on the leading edge of your keying waveform-so that 100PF in a 3 ft cable is more than enough to filter that edge. For a squarewave, this tends to round of the corners-and if there are any nasty little ringing transients on that leading edge, this filtering may be just enough to grossly reduce them-just what you don't want when you're looking for key-clicks, etc. (*2) In the case of some kind of RF-feedback problem from high VSWR, or other high power RF-related problems, such a 1X pickoff might swamp that RF problem... but OTOH, your feedback problem would then clear up somewhat, cluing you in that it was RF through the key into the TX that was the problem. Not a typical problem with modern TXs-much less with QRP. 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: Sun, 30 Nov 2003 14:09:28 -0700 (MST) From: Karl Larsen To: qrp-l@lehigh.edu Subject: [162093] FOX: Tom KV2X Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Hi Tom, please reply to this email and let me know if you want high or low Tuesday next.
