The Navy must have used cheaper maps. Karl, are you saying the students will have to learn all the sounds at once? Seems to me like that would be a killer. I have heard of sending code and having the students pick out just the ones they have learned. I guess the objective was to learn to drop a character and go on if it was not recognized immediately. It also exposed the student to similar sounds so discrimination was improved. But 40 at once? I agree with Bob, AH7I that after learning a few characters there is a sense of accomplishment and that motivates you to do more. How long would you have to work to feel you had accomplished something if the first hurdle was 40 characters? Sorry about sounding negative re: 40 characters at once. Perhaps I misunderstood or maybe it will work. Keep us informed. Breakthroughs often come when someone tries an unusual solution. Good luck.

I have an intermittent bug in my QROP Meter (http://www.jasonhsu.com/ee.html). I've designed it so that all 10 SWR meter LEDs are dark when I'm not transmitting. (In other words, SWR=1.) Let me explain my current design, and then I'll get to the bug. THE DESIGN: Here is how the LM3914 displays the SWR: The reflected voltage sample is fed to the SIG pin. The forward voltage sample is fed to the HI pin. The LO pin is set at 30mV. (This idea is from the QST article "A Pocket-Size, Direct-Reading VHF SWR Meter", which you can download from the ARRL web site.) In an earlier design, the LO pin was set at 0V. However, this caused various LEDs to go on and off randomly when I wasn't transmitting. The LO pin is set at 30mV so that when the SIG pin voltage is less than this (the case when not transmitting), the entire SWR display will be dark. The 30mV modestly reduces the accuracy of the SWR display at very low power levels (by about 1 LED between 200mW and 1W). Here is why the watt display looks like it's in bar mode during SSB transmissions: During SSB transmissions, the power levels will vary greatly within a fraction of a second, and the wattmeter display (although configured in dot mode) will appear to be in bar mode. That's because you might be transmitting at 35W at one instant, 18W at another instant, 1.1W at yet another instant, etc, and this will be reflected in the LED display. All this will happen so quickly that it will appear that several LEDs are lit up at once. This is desired. Here is why the SWR display should appear to be in bar mode during SSB transmissions: Suppose you're calling CQ at 18W in SSB with an SWR of 2.3. When you transmit in SSB, there will be instants when your transmitted power level is 0W. At zero power, the SWR meter will display an SWR of 1.0 (no LEDs lit up). At another instant, you'll be transmitting the full 18W. The SWR=2.3 LED will be lit up. There will be other instants at which you will be transmitting at a small fraction of a watt, and at these instants, the SWR=1.1, 1.4, and 1.8 LEDs will be lit due to the error caused by the 30mV reference voltage at the LO pin. To your naked eye, it will appear that all the first 4 LEDs (corresponding to SWRs of 1.1, 1.4, 1.8, and 2.3) are lit up simultaneously. THE BUG: The problem is that the SWR=infinity LED sometimes goes on when I'm NOT transmitting. Interestingly enough, disconnecting the QROP Meter from the transceiver immediately turns off the LED. Evidently, the transceiver has something to do with this. (It could be that RF picked up by the antenna/load is reflected by the transceiver and causes interference.) THE DIAGNOSIS: The bug is caused by RF interference. The 30mV reference voltage at the LO pin and 0V at the HI pin means that the 10 op amps are on a hair trigger, having only 3mV apiece, which is close to their offset voltages. It probably doesn't take much RF interference to cause a problem. This problem does NOT exist in the wattmeter part of the circuit because the LM3915 is configured to respond to much greater voltages. Using more than a 30mV reference voltage at the LO pin of the LM3914 would reduce the impact of this bug but also reduce the accuracy of the SWR measurement at QRP power levels. ATTEMPTED SOLUTIONS: I've checked my connections, and they're all OK. I've added a 100uF decoupling capacitor to the power supply. I've added a .1uF decoupling capacitor to the LM3914 power supply leads. (Yes, the capacitor is next to the IC so as to minimize stray inductance in the RF path.) I've added .1uF decoupling capacitors to the SIG voltage and HI voltage of the LM3914 (as suggested in the application notes). But none of this was enough to eliminate the bug. I realize that using long leads in the LEDs doesn't help due to stray inductance, but the decoupling capacitors were supposed to address this, and using shorter LEDs would make my instrument more difficult to build and service. (I'm not a manufacturer.) SOLUTIONS I HAVEN'T TRIED YET: I'm looking for suggestions on how to remedy this bug. The possibilities: 1. Comination of log and antilog amps (though accuracy and stability could be issues) 2. Analog Devices or TI divider ICs (though expensive) 3. Other, cheaper divider ICs (Are there any?) 4. Halve the forward and reflected voltage samples (so that the 10V associated with 200W becomes just 5V) and then feed them into PICs 5. Any other suggestions?

You can use almost any length of wire that you can find stuffed into the antenna receptacle. I have an Icom R-71 that I us in my workshop and I use a 4 foot test ire as its antenna. I also have a Kenwood R-820 there that I used about 15 feet of wire run along the window tops. I have used substitute antennas for receiving for over 30 years. Receivers generally have excess gain, especially through say 12 mHz so they can stand short antennas. Receivers generally don's gave input impedance issues so a short end fed, which is what it is, doesn't cause problems. And if your listening to SWBC stations, you are listening to very strong signals.

You have settled in a good length. Most of the other stuff is really only impatient to you. A note about the Artificial Ground. If you are planning to use resonant counterpoises you really don't need the Artificial Ground. I don's know where you plan yo run them and what you intend for separation, but the Artificial Ground will tune a 12 to 15 foot piece if wire in all frequencies very well. I use a 12 foot wire laying on the floor. Think about it, you may be making more work for yourself.

I think there is a mid-west college band named Zambonie. You are probably refering to Zamboni, the trade name of a large ice resurfacing machine. If you watch hockey or ice skating you will periodically see a large box shaped machine come onto the ice. As it quickly passes around the rink it shaves a thin layer of ice off the surface and leaves a very thin layer of cold water that quickly freezes. This leaves a nice fresh surface for the skaters that follow. I think there are other manufacturers of ice resurfacers but Zamboni was the first and like Kleenex and Coke, the name has become synomous with "ice resurfacer". It is pronounced zam BONE knee (or close. Language experts feel free to correct.) I also think there is an Italian dessert with a similar name. Hope this is what you were looking for. 73 Clint Poss KE4FDT ------------------------------ Date: Sun, 01 Feb 2004 00:25:43 -5 From: "Bill Kelsey - N8ET - Kanga US" To: "James Kelley" , "Low Power Amateur Radio Discussion" Subject: [166762] It's Zamboni Message-ID: <401C4787.28732.2AE9084B@localhost> MIME-Version: 1.0 Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Content-description: Mail message body As probably the only Zamboni driver on the list (yes - I really do drive the Zam at the local rink!)

Zamboni was the originator's name and he had a company of the same name that resurfaced skating rinks (prior to that you had to use warm water and somehow smooth it, which was, shall we say, challenging, sort of like an actual frozen pond). Kind of like Kleenex - synonomous with tissue. All Kleenexes are tissues but all tissues are not Kleenexes. All Zambonis are ice resurfacers but not all ice resurfacers are Zambonis. As for rinks, I've found more and better rinks in south Florida than I did in the DC area, or pretty much anywhere else I've been for that matter (haven't been to North Dakota though).

The QRP operators here seem to be fairly spread out making it difficult to maintain an organized club. It is our hope that if this works out to make Puyallup an annual meeting for QRP operators. For those not familiar with Puyallup, it is about 30miles SE of Seattle. At present we are slated to have a representative from ELECRAFT at the show and making a technical presentation. Additionally Bruce Prior N7RR (Mr. QRP Backpacker) will be making presentation also. As you know Bruce has reviewed many of the newer QRP radios for the various publications. We will possibly have one more speaker. In addition to the technical sessions we plan to have an operating QRP station outdoors. With the typical NW weather we may have to locate them inside a liferaft if the rains continue (smile). I would like to extend a warm welcome to QRP operators in Canada, Oregon and Idaho. For more details see: http://www.mikeandkey.com/flea.htm Generally you will find many QRP related companies like SGC, ICOM, EMTECH and have often seen the Buddipole and Paddlette Co represented in the past. Through this gathering I hope we can help to establish some frienships and help folks find operators in their respective area so they can get together for Coffee and Pie and some good eyeball QSOs.

I installed a BNC connector on the side of the case of my MFJ dummy load with a short length of wire bent 90 degrees just as it comes out of the connector (parallel to the load resistor).

Use a 5 pf to the coax, then a 220 pf to ground from that 5 pf output. This will form a 40:1 voltage divider. You can pick the output for the counter off the junction of the two caps. 5w is 22v pk or 44v pk-pk. This will give you about 1v pk-pk from the junction, somewhat less than 1 mW. The SSS frequency counter, I found I count get a count just by attaching two feet of wire and picking up my transmit signal over the air. - Dan, N7VE ------------------------------ Date: Sun, 01 Feb 2004 10:07:32 -0500 From: Lee Mairs To: rattray@accesscomm.ca, Low Power Amateur Radio Discussion Subject: [166776] Re: Still no PIC-EL!

I thought the desired value for the "low" programming was as close to ground as possible. Without R27, this would be Vce-sat or about 0.1 volts. With R27, it should be around 0.62 volts. Obviously, the circuit works as designed, so this question is just a curiosity. Fourth is not a question but an assertion: NJQRP should have dropped shipped all the PIC-ELs from a centrally located place such as Arkansas, so the packages would reach the far corners of the USA at approximately the same time. And not that it matters, I would have mine by now. 00000111 00000010, Nick, WA5BDU ------------------------------ Date: Sun, 01 Feb 2004 10:14:21 -0500 From: Edwin Lappi To: Subject: [166778] FS: PSK-80 Warbler Message-ID: <504iBaPoV1136S07.1075648461@uwdvg007.cms.usa.net> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable I have for sale one PSK-80 Warbler plus serial cable to computer plus instructions.

Well, I have to say it is quite a nice kit. The board quality was first-rate and though the instructions were a little vague and terse, it went together very well. Not bad for a couple of sawbucks and a fin! However, I do have a couple of questions. The default freq. is 14 060.00kHz, but there is a very weak continuous tone at +670Hz (14 060.67kHz). It stops upon key-closure and begins again at key-open. I don't know how much power its putting out there (at 14 060.67kHz). Incidentally, the power out at 14 060.00 kHz looks to be about 300-400mW. With regards to above, the secondary freq. is 14 060.76kHz, and it too puts out a weak continuous tone, but this one is at -870Hz (14 059.89kHz). So question No. 1 is; What are these tones? And are they transmitting out with any real energy? The sidetone is a bit loud. What are any suggestions for C8 (0.1 uF) to drop that level a tad? Final question, the tone is very raspy, the suggestion is to put an R-C combination together to soften that. What has anybody else done? It may be tolerable if I drop the sidetone volume some, but as it stands now it is very tiring to listen to for any real length of time.

Also, for additional resourced, I picked up a copy of "Programming and customizing PICMicro microcontrollers", by Myke Predko, and it seems like a very good into about how to interface to all sorts of different devices like keyboards, LCD's, etc, do serial port handling, etc. The book however, is $15.00 more than the PIC-EL. ;-) - Rich -- Richard Mulvey ------------------------------ Date: Sun, 1 Feb 2004 11:47:12 -0500 From: "Carr Family" To: Subject: [166786] Re: Need suggestions on an intermittent bug in my QROP Meter Message-ID: <000001c3e8e3$0a4f5f60$0100a8c0@china> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Jason, Based upon your description and a quick look at the LM3914 datasheet, I would suggest that your current problem is the same as the problem you had before adding the small voltage at the bottom of the voltage divider. With some voltage at the bottom of the divider and zero at the top, the top most comparitor would be the most sensitive. I suggest perhaps removing your previous fix and add an enable circuit that will enable the LM3914 only when you have some input voltage on the top of the divider. Perhaps a fet switch on the bias current?

It's called ExpressPCB (part of a two-part package, one for boards & the other for schemos, which is another story) & you can download it & try it out. You can even keep it. Why, you can use the software to draw a board & then get an estimate for gettin' some boards like you drew done for you. The schematic drawing software, well, it sucks. I have gotten so used to using DesignWorksLite that anything else is just user-surly. But I can't export the DWl stuff into the ExpressPCB stuff (at least I ain't figured out how), so I have to trust myself to draw the board up right. The board drawing software, it's good, however. You can do 4-layer boards (if you're nuts) and you can do two sided boards, plated through with mask & all that, if you want to go through the effort. I've used it so far to draw up a board for the TDA1072A that I mentioned in the other post. It was pretty easy to work out, using both sides of the board & all that. Then I used the software to estimate the cost of havin' three boards made up to my drawing. It'd cost just shy of $60 to get three boards done. No mask & no parts markings. Just the board, etched, tinned & ready for destruction. Or deconstruction. Whatever. Now . . . anybody here what ain't got intervention using this or similar software & what's their experience with it? Like I need another project! 73 Nils . . . next I draw up a board to mimic Jeff Anderson's 9-volt battery case radio from many years ago . . . ---------------------------- Nils R.

Seriously. It's a double-tuned set with variable coupling & it's huge & old-fashioned lookin' and all that. And I can hear the local NDB from Xenia on it. With an AF amp I can hear a couple more of 'em. And broadcast stations too, which is another story. Then, after I got tired of listening to stuff like that (which ain't hard, given the number of "all-talk/all-sports/all-right-wing-ranting" stations on the air), I started lookin' at a ZN414 kit that I got somewhere. I built that & hooked it up to the xtal set tuner. Soon that got boring (for the same parenthetical reason as above) & I got out my collection of other weird projects. Remember the TDA1072A single-chip thing I went through a couple years ago? Well, it's back. Same-same the TEA5551T project, which is further off 'cause it's SMD stuff. However . . . I discovered the following items (not all of 'em available any more): ZN415E -- a TRF receiver chip, 8 pin DIP, that's the ZN414 with a two stage amp for headphones. MK484 -- replacement for the "no longer available (yeah, right)" ZN414 CXA1600M/P -- a Sony 8 pin DIP that's a complete superhet with VCA headphone amp . . . uses a built in 55kHz IF & filter. You hose up the oscillator LC, the antenna LC, an AF gain pot to ground, an AGC cap, power & ground & you get an AM receiver. I'm serious lookin' for this one, if only to say I built one of 'em for SW. Spec sheet is pretty lame: no info on input frequency response, but it's at least 1 MHz. CXA1619AM/AS -- another Sony 30 pin DIP (for through hole use; it's a 28 pin SOP SMT) that's a seriously complete superhet, AM/FM with what looks like a VCA AF amp for headphones. Pins for AGC, mode select &c. Uses external IF transformers & looks like a Sony version of the TEA5710. CXA1691AM/AS -- another Sony IC, another version of the '1619 as I see it . . . Haven't really chased the differences 'cause I'm more interested in what might happen if I even find the '1600. And then there's Nick Kennedy's website for his working out a TDA1072A as a CW rx. Serious evidence that he got much, much further than I did with the '1072, which is cool . . . I looked at what he'd done & began getting that itch again. I even found my stash of '1072s and one TEA5551T that I put on one of them "surfboards" that Roger has for people who end up with SMT stuff to play with but no way of workin' out a solution. My vet's gonna love me. When he put me on these meds (to keep my hands from shaking, which is another story), he asked me to keep a log of what I do & whether the meds do anything or not. Well, I built the xtal set, didn't I? And I found these schemos & new chips & stuff, eh? And now I've got this wild idea of getting down the proto-board & trying again to see a working '1072 receiver. Even if I do scob some ideas from Nick. Something to do while I'm waiting for my copy of the 60s movie "Che!" to arrive. 73 Nils ---------------------------- Nils R.

The problem with that is the switch will be turning on and off many times per second when transmitting in SSB mode. Ripple in the power supply is something that's supposed to be avoided (hence the reason for decoupling capacitors). Another possibility is to supply a voltage at the HI pin at all times. This requires a circuit that will accept two voltages (forward voltage sample and a small reference voltage) as inputs and output the higher of the two. Or maybe it would be easier to just use a microcontroller to do these functions.

Nope, they only make it as far as the mixer, the PA is shut off. > The sidetone is a bit loud. What are any suggestions for C8 (0.1 uF) to drop > that level a tad? I use a .01 and find it quite comfortable. I haven't tried a filter for the sidetone, and you're right, it's a square wave and pretty obviously so. I found it much more tolerable with a .01uF cap, which may have had some filtering effect anyway - don't know about that. I've been meaning to play with that, but I'm still trying to find time to put my other two in cases. I find a slightly modified Radio Shack 270-1808 plastic enclosure (8 x 3 x 1") will nicely hold the RM and eight AA cells for portable operation. I'm thinking about using a BLT case for a dual-band RM. 72, Dale - n0xas -- It's a thankless job, but I've got a lot of Karma to burn off. The NEW Super PicoKeyer offers speed control by pot OR menu!

I use a couple that keep me going. You probably are appreciating building stuff more than ever. Thanks for you summary of one chio radios. A couple of things. I thought that the ZN414 was not readily available except at Ocean State for the criminally high price of $9.95. MK484s on the other hand are around and cheap. The MK484 chip is also obsolete, but there are reputed to be a half a million of them floating around in the world. I get mine from DIY Electronics in Hong Kong for $.30 apiece. And Mitsumi still manufactures and sells ANOTHER ZN414 clone, the LMF501T, which you can buy if you are willing to buy 2000 units. There are also a few of FM only chips which lend themselves to other types of radios. The TDA7000 comes to mind. And I have a bunch of TDA7088T chips. These are the ones that are in those little button-tuned FM radios that go for cheap at discount stores. I'd be willing to sens a few TDA7088Ts to anyone who could give me a good suggestion for a receiver (other than an FM broadcast radio) for these chips and would be willing to try. I'll even send a Surfboard adapter to those who come up with really promising ideas. By the way, there are a number of simple shortwave radio designs out there that use the ZN414/MK484 for an If amplifier. I am working on such a design myself--getting BFO injection into the chip is the tricky part, but there are those who claim to have done it. You have started a most interesting thread--hope others contribute.

I have used ExpressPCB a couple of times. Good quality, and if all you need to do is bang out a couple of prototypes and you need them really quick, they are almost impossible to beat. As you noted, though, it's no solder mask, no silkscreen, and the software is pretty limited. If you're not in as big a hurry, there's a better and cheaper (albeit slower) alternative. Any PCB CAD program that can generate Gerber files can be used, or download the free version of Eagle. Email the files to Olimex . They do excellent work, prety quickly. The downside is that they are in Bulgaria, but it's not much of a downside. They do need a FAX of a signed PO to go along with your credit card information for payment, but I have gotten around this by using a decent (3.2 megapixel) camera to shoot an image of the PO form, convert it to TIFF and email it. To be honest I was hesitant at first, but these guys are honest, quality-minded people who do an excellent job. I "met" the owner on the PICList a couple of years ago. I now use them exclusively for my keyer kit boards as well as other things. At $34 for a one-off with no silly setup fees, I'll make boards for projects occasionally. A 6.3" x 3.9" double sided, plated through board with mask and screen will cost you a total of $34, including delivery. Air mail from Bulgaria takes a couple of weeks, no Customs hassle or duties or anything though. They do offer express or courier delivery if you're really in a hurry. I've looked at several other places, but none that I have found work very well for small runs and prototypes. There was one that looked promising in Singapore, but their quality was so extremely poor as to be unusable, and a total waste of money. Nice guys, they just can't make boards. Olimex is the real deal, and I highly recommend them. 72, Dale - n0xas -- It's a thankless job, but I've got a lot of Karma to burn off. The NEW Super PicoKeyer offers speed control by pot OR menu!

Message-ID: <200402011214.AA41746802@mail.codenet.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii greetings, I'm deep into getting the portable station ready for FYBO and have a variety of options for battery ops. In particular, I have some li-ion battery packs that output typically 14.4 volts nominally, 16.6 or so when newly charged. Anyway, I don't want to run the AT Sprint on any more than 12 volts. One option is to just use one pack (7.2v nominal) - anyone have an idea what kind of power out and performance one might get at that voltage?? Another option would be to build a small battery control module (in an altoids tin of course) that can switch in diodes in series with the battery packs to drop my voltage. I've built Steve Weber's battery monitor circuit and can add that to the device. Anyway, would diodes be a good option to drop voltage?

I converted a TDA7021 cheap FM headphone mini-receiver, actually one with the equivalent KA22429, to a VHF receiver covering 112-163 MHz. It is very simple as all that it took was to remove a 22 pF capacitor from the oscillator tuned circuit. It demodulates AM, FM as well as wideband FM reasonably well, see app. note on http://www.semiconductors.philips.com/pip/TDA7021.html. I wouldn't be surprised if the TDA7088 was just as easy to use for VHF. -- 73, Sverre ------------------ Sverre Holm, LA3ZA www.qsl.net/la3za ------------------------------ Date: Sun, 1 Feb 2004 14:45:46 -0500 From: "John" To: "QRP-L" Subject: [166812] FS: Iambic paddle Message-ID: <004b01c3e8fc$005d8f40$4f398d41@ATHOME> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Vibroplex iambic paddle, standard with gray base.

On the first, the boards arrived via Priority Mail in a couple of days from wherever they're located (Oregon?) to NH. On the second and third instances, ExpresPCB shipped the boards via Airborne Express second-day air delivery, which took eight days and thus turned into "second-week air". That said, the boards are certainly adequate for building. The plated-through holes make building a pleasure. On the downside, I'd like to see more component-footprint and schematic-symbol patterns in their software libraries. If you're in need of software to draw schematics, you can use the Express Schematic portion of the package and generate printed copies. Also, if enough people adopt it, the software could become a handy medium for exchanging designs. 73-- Brad AA1IP ------------------------------ Date: Sun, 01 Feb 2004 15:08:41 -0500 From: Richard Mulvey To: "John J.

Read and see more about both of these fun new kits at www.amqrp.org/kits/SuperKitSunday.html 72/73, George N2APB and Doug KI6DS for the American QRP Club www.amqrp.org ------------------------------ Date: Sun, 1 Feb 2004 15:41:01 -0500 From: "Joseph Trombino Jr" To: "QRP-L" Subject: [166820] re: F.S Schurr paddles Message-ID: <00fb01c3e903$b472c520$220110ac@gateway.2wire.net> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Howdy Gang: The Schurr Proffi-2 paddles I had for sale earlier have been sold. 73, Joe W2KJ ------------------------------ Date: Sun, 1 Feb 2004 16:15:54 -0500 From: "n3drk" To: "George Heron N2APB" , "Low Power Amateur Radio Discussion" Subject: [166821] Re: "Super Kit Sunday" at AmQRP meetings this weekend Message-ID: <01b401c3e908$9410e050$6400a8c0@n3drk> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit They may continue to provide fun and excitement but where are the 6 month due Homebrewer Magazine? john ----- Original Message ----- From: "George Heron N2APB" To: "Low Power Amateur Radio Discussion" Sent: Sunday, February 01, 2004 3:39 PM Subject: "Super Kit Sunday" at AmQRP meetings this weekend > The American QRP Club continues to provide more fun and excitement than > QRPers should be allowed to have with its kits, online projects and weekend > forums! > > This time, in a coast-to-coast "double-whammy", the AmQRP unveiled its two > newest kits on this Super Bowl weekend. > > Yesterday at the NJQRP Club monthly meeting in New Jersey, ELSIE the > Atlanticon Kit was first shown and demonstrated to about 35 QRPers in > attendance. > > Then this morning at the NorCal monthly club meeting in California, the Tin > Ear Receiver was first shown and demonstrated to about 30 QRPers. > > Read and see more about both of these fun new kits at > www.amqrp.org/kits/SuperKitSunday.html > > 72/73, George N2APB and Doug KI6DS > for the American QRP Club > www.amqrp.org > > > ------------------------------ Date: Sun, 1 Feb 2004 16:27:42 -0500 From: "George Heron N2APB" To: "QRP-L" Cc: Subject: [166822] Re: "Super Kit Sunday" at AmQRP meetings this weekend Message-ID: <00d701c3e90a$3adc3280$6400a8c0@n2apb1> MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit As the magazine's web page explains (www.amqrp.org/homebrewer), the issue is in the mail and subscribers will be getting it as soon as the pastal service gets it to your mailbox. ~George N2APB ------------------------------ Date: Sun, 1 Feb 2004 16:33:59 EST From: Ke9xq@aol.com To: qrp-l@lehigh.edu Subject: [166823] FS: Circuit Board Material Message-ID: <1d8.19904f0a.2d4ecac7@aol.com> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Greetings This is just a feeler, to see how much interest there is in getting some of these old boards again. I have some old single sided material here that is looking for a good home, and if there is enough interest, I'll package it up and let you know what the postage will be. This is old material, but still very good or usable stuff, and it's going to be basically free, I'll charge for the envelope and the postage. I'll find out how much it will cost to mail out probably this next Wednesday. Any interest??? Probably let me know off the list. 73 72 Bill KE9XQ ------------------------------ Date: Sun, 1 Feb 2004 15:40:53 -0600 From: "Craig Johnson" To: , , Subject: [166824] Re: [qrp-l] Re: PIC-EL up and running - 2 questions Message-ID: <01e601c3e90c$11d30fb0$6201a8c0@cbjp2> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Nick, > Here's the original "2 questions" post from Brian Riley, which I think > was answered by John Mc: OK.

Is this OK or is the zener "off" ??? I think it is OK. Probably just some voltage drop across R6, which means the zener is not really being used as a voltage limiter. The zener is only there as a precaution - to protect everything in case someone hooks up a much higher voltage power supply.

Obviously it is getting a "LOW" on the PIC pin side of the LED. Since it works OK on other tests, it must not have a short to ground. Does the LCD work? LED3 is a on one of the LCD data lines. Check the voltages on both sides of R18. There is nothing that directly associates PB3 with LED3 - it's just programming. PB3 may well be OK. Check the voltages on both sides of R35 to make sure. Does the speaker work? If PB3 is "shorted", the speaker will not work. 73, Craig, AA0ZZ ------------------------------ Date: Sun, 1 Feb 2004 16:42:11 -0500 From: "John J.

New, old stock. Please limit one or two per order for now. These are Panasonic Model # KX-A11 AC Adapters Input is listed as: 120VAC 60hz 12W .1A Output is listed as: 12vdc 500mA They come with about 3 feet of lead wire and have what looks to me like a 2.5mm plug on them. The center is wired as negative. If that's a problem, cut the connector off and rewire it for center to be positive. I'm asking $5.00 for the item plus $3.85 shipping in the USA Let me know if you're interested. ============================================ Agnus dei, qui tollis peccata mundi, dona nobis Pacem. ============================================ KB9BVN/QRP QRP-L 1540 QRP-ARCI 10223 39.558 N 86.095 W Johnson Co., Indiana GRID: EM69WN - Elecraft K1 - Attic Dipole - 5w Member of the ARRL - SOC #400 FISTS 5695 CC 764 FPQRP #-57 ============================================ ------------------------------ Date: Sun, 1 Feb 2004 14:08:35 -0800 From: "Donald Jacob" To: "Low Power Amateur Radio Discussion" Subject: [166827] Beacon Report addendum Message-ID: <009b01c3e90f$f025dba0$6501a8c0@socal.rr.com> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit KG6CYN/B Time: 06:10 2/1/04 (UTC) Name: Don (first only) Call: WB5EKU ( for log) R/S: 5-4 to 5-7(readability & strength) Grid: DM04sg( e.g., EM22cv ) City, State North Hills, CA (San Fernando Valley) KH6B/B Time: 12:38 UTC Name: Don Call: WB5EKU R/S: ESP to 5-4 With S5 to 6 noise Grid: DM04sg City, State: North Hills, Ca ------------------------------ Date: Sun, 1 Feb 2004 17:23:05 -0500 From: "Carr Family" To: Subject: [166828] Re: Need suggestions on an intermittent bug in my QROP Meter Message-ID: <000001c3e911$f6d0c9e0$0100a8c0@china> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Jason, >>Correct me if I'm wrong, but it sounds like you are suggesting that I use a >>special switch that supplies the LM3914 its 12V of power ONLY when there is >>a significant input voltage. The problem with that is the switch will be >>turning on and off many times per second when transmitting in SSB mode. I was suggesting that you do something with pin 7. I am assuming that the LED's will be off when the bias current is zero. The datasheet says " The ability to modulate LED brightness with time, or in proportion to input voltage and other signals can lead to a number of novel displays or ways of indicating input overvoltages, alarms, etc." Ron WA1VGB ------------------------------ End of QRP-L Digest 3183 ************************ --------------------------------
