But it was something to see being on the flight line less than 500 foot from the runway and seeing that bird.

Right now it is at $29-which is a pretty good price for an HD-1250-with 3 days left. For you collectors there is also an HM-10A Tunnel Dipper, again under same category ONLY.

EDU" Subject: [160820] SA602 Question Message-ID: MIME-version: 1.0 Content-type: text/plain; charset=iso-8859-1 Content-transfer-encoding: 7BIT I'm sure there are a lot of people reading this list that know the '602 inside and out, since it's used in so many excellent receivers. I am goofing around with a Manhattan style "Sudden" receiver and am trying to find information about the capacitor values for the colpitts oscillator using the transistor between pin 6 and 7. Compared to a standard Colpitts it has a DC blocking capacitor between pin 6 and the tank. Dumb Question Number One is how does this cap figure into calculating the resonant frequency of the tank? Question 2 is how critical are the two caps in the traditional pair of caps whose centertap goes back to the emitter (pin 7)? Do these also affect resonant frequency? Right now it is oscillating ok on 14 MHz, but even using a 10pF variable cap I get almost 1MHz of adjustment and I don't want to use this for SWL. Any of you guys know where there is a good reference about this stuff? I have "Experimental Methods in RF Design" and have read the section about Colpitts oscillators, but due to a technical dearth am having trouble relating it to the slightly different circuit of the Sudden. EMRFD has a bit on the Seiler oscillator, and that gives the Xc's of the different caps, but when I applied these to the Sudden it didn't even oscillate. The SA602 datasheet shows the exact setup used in the Sudden, but not much info on the mechanics of determining the values, probably presuming if you are using their part you know how to design a Colpitts oscillator, which is reasonable but in my case incorrect. I have also googled with "SA602 and Colpitts" and surfed to most of the promising sites but still came up empty handed.

If anyone has anything in particular they would like to do at the Forum, or anything they would like to have discussed, let me know and I will see what I can do to make it happen. We usually get an enthusiastic crowd of 20 to 30 QRPer's. It has turned out to be one of the bigger forums at the hamfest - that is why they have not scheduled anything after us in the White Room.

As a kid I used to love going to the surplus store and find boards with lots of sockets. Once I got home I grabbed a screwdriver and popped them all out. Sorted them out on the table top. Usually knocked them off the table pretty quick. There are STILL IC's embedded in the carpet upstairs, most of the ones left have bent pins and aren't dangerous. I walked very lightly in that room... Never did get poked too seriously. Did once with a sewing needle tho...

(Hams Expounding Low Power)--smile I wanted to call your attention to the group on YAHOO http://groups.yahoo.com/group/pQRP/ This is designed to have basically Pacific Northwest issues and information passed and will supplement the QRP-L and QRP-F lists already in existence (not replace them). If you are looking for a local QRPer to operate with during an event or want to call for an informal coffee meeting this will be a good source for communicating. Note you do not have to be registered with YAHOO to get the mailings or to send messages to the group. the site noted above will list the most recent messages. To access the archives you wll have to REGISTER with YAHOO be we are looking at changing that. If you have any questions regarding the GROUP please direct them to Terry wx7s@cfsystems.org You folks in Eastern WA feel free to join in also.

That reminds me of another problem... I have a number of boards of various types that seem sharper than normal. Some PC boards don't bother me...

Message-ID: <3FABE491.165ABF27@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Alex, There are several issues to contend with when choosing a filter. The absolute best filter choice is the one that the manufacturer has designed for the rig. However, other filters may work. The points to ponder are: 1) The filter impedance. The rig has been designed to accept a certain impedance for the filter in the IF stages. This is not to say that you could not design an impedance transforming circuit, but it will require more parts and space. 2) The filter's internal loss. You will probably have to design extra amplification for your filter. Again, more components and more space. 3) Filter bandwidth and type. There are filters and there are filters. CW filters are ate most general in terms of shape factor. SSB filters generally have shape factors tailored to their intended use. 4) Space. This may seem like a trivial matter in a boat anchor, but in a small modern radio it can be a problem.

End fed wires need only one support, or in the case of a longer wire, two supports whose spacing isn't critical. One wire can cover multiple bands. I use a 170 foot wire to cover 80-10, and shorter wires for backpacking or to cover 40 and up, etc. Of course, the radiation pattern isn't as predictible as a dipole, but then neither is that of a dipole is most compromise field setups. You'll need a counterpoise wire of at least a quarter wave on your lowest band, laid out on the ground in the most convenient direction. 73, Bruce N7CEE ------------------------------ Date: Fri, 7 Nov 2003 13:50:24 -0500 From: kwike@gdls.com To: "Low Power Amateur Radio Discussion" Subject: [160861] Re: Beware of Integrated Circuits (under foot)!

For a portable, limited use antenna you might be able to get away with RG-174 coax. This stuff is small and lightweight. The loss is not so bad that it cannot be used. However, RG-8 type cable would be better. I believe there is an RG-8 cable of small diameter. Of course you could use RG-57 cable too. 73 ------------------------------ Date: Fri, 7 Nov 2003 12:09:19 -0700 (MST) From: Karl Larsen To: charlescurrey1@imcingular.com Cc: Low Power Amateur Radio Discussion Subject: [160863] Re: Huntsville, AL Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII On Fri, 7 Nov 2003 charlescurrey1@imcingular.com wrote: > Anybody know of a good ham radio store in the Huntsville area?

When I was in college I got an old Teletype that Dad (who had been a RTTY operator in the Navy) was helping me put on the air. One evening he told me we needed to make some cables for it. The next afternoon when I got home from school I plunked down on the floor of the shack with the Weller, a spool of zip cord, and a pile of 1/4 inch phone plugs. I'd strip the ends of the wire, stick on a plug, clamp the wire between my feet, and hold the soldering gun in one hand and solder in the other to make it all permanent. Dad was surprised to find me in that position when he got home. He said he never saw one of his kids in the Navy assemble cables that way.

John, At work I've noticed that if we use IC sockets with stamped contacts (typically made by Augat) the socket leads that extend through the board are more vicious than round pin sockets. The socket leads are usually too short to be trimmed off by our post-solder lead trimmer, too, so they don't get removed. Also, some boards are panelized so there are several in one sheet of PCB material. They're all stuffed and soldered as if it's one big board, then the smaller boards are cut out of the panel. Depending on how they're attached, they might just be broken out of the panel instead of cut free. If they're broken out, the points where they were attached are very rough.

Hi Steve, I suggest if your going to be car-camping that you use the bigger Radio Shack RG-8 or the rg-58 that has a multiconductor inner wire. I have the rg-58 on my w3ff home made dipole and it works very well on 20 and 15 meters.

Well, actually, at HF for short runs, it's not too bad. And you won't have power issues with QRP. RG-8 is better, but for short runs on HF would you notice? Probably not. And you can get RG-8x and RG-8M, much smaller and easier to work with than RG-8. But are you running with a tuner? If so, consider just hooking direct with a long wire. Or even 300 ohm twinlead. I have a 'portable' antenna I take camping with the Boy Scouts that I hook to my K2. It's a 40m dipole made with 22ga speaker wire stripped to a single strand. I feed it with the CHEAP 300 ohm twinlead. Takes just a few minutes to put up with 'jute' cords, and just minutes to take down. I hook it to the K2 with one of the BNC to binding post adapters. Works gangbusters on all bands except 12M. 10M, 15M, and 17M I have to retune if I move around too much, but otherwise it's nice. I run the same thing here at home, but it's put up with 18ga speaker wire, and the high quality 300ohm twinlead. I also have a good quality rope stretching out the ends to make it through the winter. The jute stuff is lucky to last a whole week at the scout camp.

One number about concrete that I found in an obscure article was that it was about 100 ohms per foot. I guess many of us ol' outdoor dogs like going around barefoot. HI!

The consensus is that RG-174 would "do the job" but would carry with it the pain of attaching connectors and the increased power loss over an equal length of RG-58 or RG-8. Many suggested using an end-fed halfwave with a quarter-wave counterpoise. That is the exact setup I had this past winter -- that is, until the family dog decided to snag the tension cord, pull the wire down, and chomp it into pieces. I will try the halfwave again.

This stuff is lighter than RG-8X and has even less loss. It should use the same reducers for PL259's as RG59 does. I've used it successfully for Field Day (QRP) and on DXpeditions to the Bahamas. The only drawback I see is that it is not as flexible as RG-174 and RG-8X. As far as I'm concerned, RG-174 has no place in QRP.

Comes preloaded with software which makes it do a bunch of neat things. Go to and search on butterfly to learn more about it. Seemed like a natrual to make a DDS controller and display out of it. So, I've been addapting my multi-band, DDS VFO control software to work on it. Got it mostly working, but still have a way to go before it's totally finished. On the plus side, you'll be able to load this software into the device yourself, using just your PC and a DB9 connector to your serial port. The down side is you'll have to down load a 20 meg zipped program from Atmel to do it. (took over an hour with my dial up) But that will also give you the ability to write your own software for the chip too. When I get the program finished, I'll see if I can talk Geroge into putting it on the amQRP web site for download.

Even on the lower bands the loss is too much for me. My backpacking antennas are all end fed wires, and my non-backpacking field antennas are fed with balanced line. Oh yeah, and my two home antennas (a 170 foot horizontal loop and a 33 foot vertical) are fed with balanced line. The only coax I use is from balun to tuner to rig, and for the VHF/UHF antenna that I hardly ever use, and that's all RG8 or better. -- 73, Bruce N7CEE -- Bruce Grubbs Outdoor Photographer-Writer PO Box 22065 Flagstaff, AZ 86002 928 606 5225 E-mail: mail@brucegrubbs.com Gallery: www.brucegrubbs.com ------------------------------ Date: Fri, 7 Nov 2003 16:13:08 -0600 (CST) From: Dale Botkin To: QRP list Subject: [160886] New soldering station Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sorry, just had to tell someone who might care... Mr. UPS Man just delivered TWO boxes of goodies. One is parts to finish a couple more Rock-Mite portables and my son's bass amp, the other is my new Weller WES-51. SOOOO nice to have a decent soldering station in the shop again, after putting up with "field-grade" irons for a few years since my WCTPN bit the dust! Ahhh... now to go finish up some projects! 8-) $69 after a $20 mail-in rebate, by the way, from Action Electronics and a few other places. No relationship, just a customer, yadda yadda. Not bad for a temp-controlled iron with auto-off (important for someone like me!) 72, Dale - N0XAS -- It's a thankless job, but I've got a lot of Karma to burn off.
