The frequency the lander used was the same as the last stage of the Saturn booster telemetry channel, which was kept active so it could provide information until it crashed into the moon and set off seismic sensors from an earlier Apollo flight.

I didn't see an earlier message, but it sounds like you are referring to the Greater Piedmont QRP Club's "Rock Mite Flea-fight" last year. The year before was the "Rock Around the Clock" event, and both were held on Straight Key Nights. It was the sense of the club members and our "special" stations (one got mega-points for working them) that SKN created loud, crowded bands, less than optimal conditions for making QSO's while rock-bound. So for 2004 we intend to move the date, but haven't landed on a specific one at this point. Any favorite dates out there that won't conflict with some major (add name of contest/event) that will overwhelm our little rocks? We're open to suggestions. 73, Ken KG4FGC John Sielke wrote: > I'll try this question.

My troubleshooting involved the following with no changes. changed bands, modes, all controls(squelch-etc), unplugged keys, disconnected antenna from jack, I didn't change power supply. operation is fine xmt and rcv all modes. not having service manual I am stuck, its only annoying but I would like to address it. Oh I did do the mod some months ago(green wire cut and input a code on pwr-up) for the 60 meter band which worked fine. Hoping someone might have the answer on this. I did send yaesu an email but no response. Tnx Jim kw3u ps I think I solved my posting problem, under format, rich text(html) was marked, changed to plain text.

It's real accurate and covers 100 KHz to 160 MHz in 1 Hz steps. Output adjustable and metered from .2 to 1.0 Volt RMS into a 50 ohm load. I thought it was 1 V P-P but found the specs and its RMS (+3 to +13 Dbm). It camed out of a scrapped GE MRI unit from a hospital.

(For you that are not from the Houston area, that is about a 100 mile trip one way). I happened to listen to the shuttle on the 147.760? repeater while I was driving down Hwy 90 one day. The shuttle had just undocked from the ISS and was in it's own orbit returning from earth. The person on the shuttle doing the talking mentioned that they were just coming up on the California coast. They would be going over San Francisco and that in about 15 minutes they would be going over Chicago!! Talk about moving! That was better than 5 miles a second. It was going so fast that I believe that if I was standing on the side of its flight path and could see it coming towards me that for a few seconds as it approached me and then went away from me, it would litterally become invisible. 73/72, Dan Harriman Orange, Texas At 19:09 02/04/2004, you wrote: >In the Clear Lake, TX area (Mission Control Houston) the traffic is >pumped into the local two meter repeater in real-time.

Somewhere in the house I have a bunch of cassette tapes of Apollo 12, 13, 14, 15, 16 & 17 - featuring the commentary and word pictures painted by Walter Cronkite and Wally Schirra. That was before I got involved in Ham radio. For the Apollo program, I don't think outside of the Houston area that you heard much on any 2 Meter repeaters. When the Shuttle program was "new and exciting" (like it's still not exciting !!!) it seemed there were 2 meter repeaters rebroadcasting Shuttle audio all over the place. Doesn't seem like anyone does it anymore. So I ask the question. Next year (or later this year ???) when the Shuttle program resumes, will we be able to hear re-broadcasting of Shuttle audio perhaps by tuning in the various NASA affiliated 2 meter repeaters (such as WA3NAN) via Echolink? Do THEY still do it anymore? 73 de Larry W2LJ - Vivat Morse!

It may be 6 more weeks of poor conditions on the high bands, but 40 and 80 continued to be the workhorses. Overall conditions were down a bit from last month with 40 noticeably weaker. A handful of brave souls(especially WA9TZE, KH6B, and WD7Z) worked a few on 20. WA9TZE snagged a couple of locals on 15 and 10 for the only activity on those bands. The total number of logs was 76. That's up 2 from 74 last month. However, a computer glitch ate one log from someone named "Yo". If that was your log, we're sorry. Send it again and we'll include it in next month's 'Late Logs' section. Here's the band statistics: Band This Month Last Month 80M - 550 522 QSOs 40M - 1085 1290 QSOs 20M - 80 15 QSOs 15M - 2 0 QSOs 10M - 2 0 QSOs Total - 1719 1827 QSOs Skinny Winners - Again this month, Doc K0EVZ and Steve N7SR fought it out for the Skinny honors. This time Doc finished on top with one more QSO and a shade less weight. Clearly, this is becoming a battle of the Titans. Well, QRP Titans... Third Skinny was Phil K4PQC with the lightest setup in the Sprint and 31 contacts. Tubby Division Winners - Jim WA9TZE was this month's tubby winner with 102 contacts on all five bands! It was another excellent performance from Jim. See the Soapbox for Jim's winning setup. Last month Tom K3TW edged out Todd N9NE with 91 and 90 points respectively. This month Tom K3TW edged out Todd N9NE with 81 and 80 points respectively. Wow, talk about competitive! Special Recognition, Outside Operation - With winter at full force, most of us were sure to stay inside. The closest we got to roughing it was Charles AB4VF who "Operated with a full wave 20 mtr loop on my balcony. Wx was just right here in Central Florida." Late Logs - Everyone was prompt last month and there were no late logs. Way to go, team. RESULTS - Each contact received one point. If you didn't tell us the weight of your station, or if your station weighed more than an ice sculpture, we assigned a weight of 30 pounds. The soapbox is published separately in the February issue of The ARS Sojourner which comes out soon. Don't miss it! www.ARSqrp.com We hope everyone had a good time. See you in March!

Greetings Folks I have some VERY thin flexible doublesided circuit board some of you will be interested in. This is so thin, it is hard to believe it is not just a thin sheet of copper, but I measured it with the OHM meter and it is indeed doublesided material. I have decided to offer my circuit board material in three or four steps, most of which is going to be free, but the first offer is one dollar and a self addressed envelope. Only one stamp is needed and I will put 5 sheets that are as long as the envelope, that's letter size or business size by 1 3/4 inches. The original size is 1 3/4" by 11 1/2" so if you send business size envelopes, you'll get a little more material. I have enough of this for thirty offers, and will wait for one week for the orders to come in and mail them all out at the same time. If, there are not thirty orders for this I will take and add another board or two to the orders received so you might receive 6 or 7 sheets. So, here's the deal 5 sheets of doublesided material 1 3/4" by 8 1/2" for one dollar and a self addressed stamped envelope. I'm not sure how to handle the over the boarder orders, if you fit that bill, and are willing to see what is needed, you are of course welcome to take advantage of this. I made the offer in this fashion because I wanted to make sure there were enough boards to go around, which of course limits the material available. If there is not that much need, then I will add a little more material as noted. Please also note, this is not taking place of the freebies coming up. Thanks for the bandwidth, check with me to see if there is still material if you do not want to throw away the stamp or two, I would mail you back the dollar if I ran out. 73 72 Bill KE9XQ ------------------------------ Date: Wed, 4 Feb 2004 19:48:31 -0800 (PST) From: Lloyd Lachow To: Low Power Amateur Radio Discussion Subject: [167069] Re: Transmitting on the Fox frequency - long, pontifical Message-ID: <20040205034832.9992.qmail@web41008.mail.yahoo.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii --- KXBill wrote: > "And certainly, > it's appropriate for the Fox to ID at least once > every > ten minutes or less." > > Lloyd, I agree with you and I believe the Fox must > also ID at the end of > each QSO. Please flame me if I'm wrong. > Cheers to all > KXBill&& Bill, From the Rules: "The Fox's information may in some cases be "deemed" to be exchanged. That is, the Hunter need not acknowledge the Fox's information, and the Fox may work a list. For example, the Fox may call several stations and acknowledge their information one by one, while sending his own information only once for the list." That's what that means. In this setting, since everyone knows who they're talking to, the Fox just has to ID as any station in an extended QSO would. The FCC Regs say, "Each amateur station... must transmit its assigned call sign...at the end of each communication, and at least every ten minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions." In the regs, they also mention "transmissions," and I get the sense that, although I couldn't find the terms defined, a 'communication' might be considered to consist of a number of 'transmissions." In a rag chew of an hour, f'rinstance, you only ID once in awhile, and again at the end of the QSO, or 'communication." I think the whole Hunt would be a 'communication,' with the Fox ID'ing every so often - there being clarity about where his transmissions are coming from - and the bit above from the Rules of the Hunt is to try to help Hounds figure out why they might be having what feels like an incomplete QSO, with no Fox ID. So consider yourself flamed with a plethora of verbiage. Flayed is more like it.

Had about forty requests, three of which were from Canada. I took a couple boards with me and priced the regular mails to Florida from my QTH and was kind of disappointed at the price. And found that N2GO had the right idea with the flat rate envelopes, so picked up a bunch of them today, and will start making the boards fit, and picked up three flat rate to Canada envelopes. I'm not sure how much board I can stuff into these, but the directions on the Canadian envelopes say I cannot go over 4 pounds, and I think the 4 pounds will come before the envelope is stuffed, so guess we'll see what transpires. So, here is the deal folks: 1. Write me off list, to make sure you are on the list. 2. Canadians send me 6.00 US or equivalent, seems like quite a difference, and locals 3.85... This is what they are charging me for shipping like I said flat rate. These Monies can be Paypal, or whatever suits your fancy. 3. When the monies arrive, I should have the envelope all ready to mail out. Just to give everyone a heads up, I only go into town 2 or maybe 3 times a week, so have a little patience. 4. As I said, I had 40 requests, and if 40 of you order, I'll need to cut up some more board so, I'll give you a heads up before you send in your order, that I need some more time to cut this up... I want to cut it up outside, and it's been cold out here... : ) I think I have enough for most of 30 orders so far. So the first orders should not have to wait at all.

First, the unit is dBm, not dB. That is, the quantity is -107 dBm which describes a power level 107 dB below one milliwatt. IT is meaningless to way that one microvolt across 50 ohms is -107 dB. A reference must be stated, hence the term dBm. The math is the usual dB = 10*log (P2/P1) where P2 = (one microvolt) squared over 50 ohms, expressed in watts P1 = 10^-3 watts The ratio of P2 to P1 is your 2*10^-14 watts divided by 10^-3 watts which is 2*10^-11. This is a pure dimensionless ratio. Taking the log of this and multiplying by 10 gives -106.9 dB or -107 dB for short. Since the reference power used here is one milliwatt, we express the power ratio in dB in terms of dBm. So the relationship is that one microvolt across 50 ohms corresponds to a power level of -107 dBm. I think that what you were missing is the reference of one milliwatt. 73, George W5YR w5yr@att.net ----- Original Message ----- From: "Karl Larsen" To: "Low Power Amateur Radio Discussion" Sent: Thursday, February 05, 2004 7:12 AM Subject: -107DB > > It is said that a signal which is 1 micovolt is a -107DB signal > in the Elecraft paper.

Let's start with the basics: 1) Install FPP. Hopefully you've installed FPP as described in Lesson 10, posted on the project website. Having gone through this you will have successfully installed the program, acivated the driver and seen some lines wiggle on the board. If you haven't done this yet, you should focus right here first before proceeding. The cable you need for connection between the PC and PIC-EL board is actually required in this first step, but for review here again it is a standard straight thru 9-pin DB9M (male) to 9-pin female DB9F connector. You can pick this cable up at many computer supply places like Staples, Best Buy,Mouser or even from Radio Shack ((p/n 26-117B). The cable plugs into the RS-232C serial port on your PC and the other end plugs into the PIC-EL board. If you only have a USB port, as some more modern computers come these days, you'll need to get a USB-to- RS232 adapter, as explained elsewhere on the project page. Another thing that's important to remember doing when a PC application such as FPP is attempting to use the serial port is to "disable" other programs also using that same swerial port. For example, on my own system I need to "exit" my HotSync program that talks to my Palm PDA in the docking cradle. Another thing that often commands the serial port, effectively blocking its use by other programs, is an IDE development program (perhaps like MPLab, and certainly like the Motorola ICS08 IDE that I use for the HC908 Daughtercard development). Lastly, be sure that you have a sufficiently high voltage power supply connected to you PIC-EL board. Although the board can run off a 9V battery, as I've done at our club meetings, you'll need to have at least 12V present on the connector in order to geneerate the minimum "programming voltage", called Vpgm. Okay, now that the cable is connected, you've got FPP loaded and turned on, your PIC-EL board is powered by at least 12V, and you've manually wiggled the lines as described in Lesson 10, it should be a piece of cake to program a PIC on the PIC-EL board. 2) Obtain the .HEX program The HEX file is the new software you will be burning into the PIC. You can download the TestSoftware.ZIP program from the web page, which will create a bunch of files on your computer when unzipped. The T- PICEL.HEX file contains the Test Program in "hex ascii" format, which is just a specific data format expected by the FPP program. I normally place all the software files into a folder called PICsoftware. 3) Load the T-PICEL.HEX file into FPP. Click on the LOAD button and navigate to wherever you unzipped the TestSoftware.ZIP files on your local computer (like the folder called PICsoftware). You will see the t-picel.hex file listed there - just doble-clik it and the hex ascii code will load into the FPP buffer. You will see that code in the FPP window. 4) Slide mode switch S1 DOWN to PGM MODE. You need to move the slide switch S1 to the DOWN position in order to put the PIC-EL board into the PGM MODE. The LED next to the switch will turn on when you do this. 5) Erase the PIC currently plugged into the PIC-EL board. You first need to "erase", or clear out the software program currently in the PIC's flash memory before you are able to burn a new program into the PIC. Click the ERASE button to do this, and if successful you will see a simple message pop up saying "PIC is erased". 6) Burn the new code into the PIC. Now that the PIC memory is empty and you have the new program (t-picel.hex) in the FPP buffer window, you are all set to burn the program into the PIC. Click PROGRAM on the FPP application window and confirm your desire again in the pop-up window. It will take a few moments for this short program to be burned into the PIC, but when complete FPP will display "Device programmed!". If it says "Programming failure", you obviously have a problem like the PIC was not first erased, power supply wasn't connected or sufficiently high, cable was not plugged in, etc. 7) Slide the mode switch UP to go into RUN MODE. Now that the programming is complete, you next need to put the PIC-EL board back into RUN Mode. Do this by sliding Mode Switch S1 UP, and the PGM LED will turn off once again. 8) RESET the board to start up the new program. Although not always necessary, just press the RESET pushbutton on the PIC-EL board to start up the new program just programmed into the PIC. Hope this all helps ... please let us know how it works out for you. 73, George N2APB ---------- Original Message ---------------------------------- From: "Dick" Reply-To: Dick Date: Thu, 5 Feb 2004 12:36:40 -0500 >I cannot locate any step-by-step info on FPP to load programs into PIC-EL.

Dave uses Yo as a tag because NC7J is a club station and there are so many Daves in the club. Dave had 66 QSOs on 40 meters and 30 QSOs on 20 meters for a total of 96 contacts and second place in the Tubby division. That is an outstanding effort. That moves Tom K3TW to third and Todd N9NE to fourth in the division. The corrected results will be posted on the Adventure Radio Society web site.

Looking around for a "portable" power supply to use with my PIC-EL, I found a box with multiple wall-warts in it. Of the five (5) different "12V DC" power supplies tried, every one of them put out between 16 and 17 Volts DC.! Probably not a good idea, since the electrolytic caps at the input of the PIC-EL are rated 16V. Fortunately, my local surplus store had a box of "Regulated 12V DC @ 1.5A" wall-warts for only $8 each. Not only does it put out a _clean_ 12.16VDC, it's a "switcher". No, not a peep on a nearby receiver. There is broadband noise audible if I put my Sony ICF-2010 right up next to the power supply, but inaudible a couple of feet away. Certainly good enough for "experimental" operation. 73, Garey - K4OAH Atlanta ------------------------------ Date: Thu, 5 Feb 2004 14:52:57 -0600 From: "Lew Paceley" To: "Low Power Amateur Radio Discussion" Cc: , Subject: [167101] Re: Elmer 160: PIC-EL -- Manual, Section 11 Message-ID: <003701c3ec2a$09ee4e60$6501a8c0@swbell.net> MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit Hi John, The voltage at TP-A (Vpgm) is determined by zener diode D5 and transistor Q3.

I believe the manual is in error. Perhaps George or Craig can jump in and confirm. I would double check to make sure R5 is 22K though.

I have a few questions. I've scoured the web searching for help first and have found nothing to help. As far as I can tell I am transmitting a signal. I am using a lightbulb as a dummyload and am able to get a signal on my Shortwave radio across the house. My troubles some in two forms. A. If I have the Pixie to near my Shortwave, even when key is up, I am getting constant signal on my radio ( whine). My guess is that this is due to the fact that the Pixie Oscillator is always running, but only transmits through the antenna when key is down. Perhaps this is due to stray RF created near the Rig. Once I move out of the room, the signal during key up stops. B. I have sound coming through my earphones but can hear no CW coming through. I am tuned to the same frequency on my shortwave and hear CW through the SW however, I don't hear the same signal through they Pixie. Some of the CW coming through the SW is fairly strong so I would assume the Pixie could pick it up. This audio sounds real up and down, a hiss that resembles what I'd think I could hear, but comes and goes loud and quiet, hope that is a good description. I have joined a local ham club and have access to an oscilliscope ( if i can figure out how to use it ), I have a voltage meter. Any assistance on where to go for direction would be GREATLY appreciated. Thanks a ton KC0RFC __________________________________ Do you Yahoo!? Yahoo!

Look at the page, http://www.atc-frost.com/products/design/va.htm It is reverse then what you asked, but you should be able to figure from here. I was not aware of all of the issues with the ratings. A close approximation is that the 24V 40VA transformer will, with a full wave bridge configuration, deliver about 28VDC at 1A. Check my math using the page above.

If the voltage is 24 volts and the secondary can sustain a 40 VA load, then the current associated with that VA level is 40/24 = 1.67 amps. Note that the transformer will consume more than 40 VA from the line supply due to losses within the transformer. 73, George W5YR w5yr@att.net ----- Original Message ----- From: "Tom" To: "Low Power Amateur Radio Discussion" Sent: Thursday, February 05, 2004 3:43 PM Subject: Transformer Rating > Hello, > > I picked up some transformers awhile back to make a power supply and I'm > not sure what the output rating means.

I've never built a Pixie but I read the schematic once. :) A. You're correct. The Pixie oscillator is always running. It acts as the Beat Frequency Oscillator when you are key up so you can hear other stations. It acts as the transmit oscillator on key down to generate a signal others can hear on their radios. The oscillator is not very powerful so any appreciable distance from the radio will cause the signal level to drop off quickly. B. No signal/modulated noise could be due to a couple of things. There's not a lot of gain in the Pixie so you definitely need a good antenna and feedline. If the station that is transmitting is right on your local oscillator frequency you won't hear anything. To hear a station it needs to be slightly above or slightly below the local oscillator frequency. I'd recheck solder joints in the receive path and make sure all the components are in the right place first, if you haven't already. I'm not sure what DC power the Pixie uses but I'd also make sure you're getting the correct voltage level applied to the rig. >From your description, it sounds like the product detector isn't working properly. As I vaguely remember signal detection is done through the power amp/output transistor so perhaps there's something you can find there that could give a hint. The most straightforward way to confirm what's happening is to use a signal generator to pipe a low level signal straight into your antenna jack. See if someone at your ham club can help you do this. A great kit to help you solve problems like this is the VE3DNL marker generator available from the AMQRP club page. It's a "poor man's" signal generator and I use mine a lot for debugging these kinds of symptoms. Shawn, although the Pixie is inexpensive, it's not a good first QRP radio. The Pixie puts out too little power and the receiver is just too simple to be more than a novelty. I would call it an expert's radio. Yes, it can make contacts but they are likely to be few and far between. My suggestion would be to spend just a little more money and get a Small Wonder Labs SW40+ and see if you can get a local Elmer to help you through the process of building it.
