I got a 559 and was running 40 watts into a dipole, when I dropped to 5 watts I was still 539... We always have WARC bands to get away from the rat race on the other bands.

Then I found the famous QRPp Special Regen Issue and I knew I was going to have go through this again. :-) This time, however, I have been enjoying SWLing with the solid-state regens I built rather than trying to use them as communication receivers coupled with a transmitter for QSOs, and I must say the sensitivity, selectivity, and audio quality are just truly amazing. For the past month I have been using the MFJ WorldBand 8100 Regen and the TenTec 9 Band Regen to discover the joy of SWLing with a regen receiver. This afternoon, while working in the basement shack I found RTE Radio 1 (Ireland) on 13.640 just booming in with nothing more than two hookup leads for an antenna connected to the TenTec 9 band regen . We are talking maybe two feet of wire for an antenna in the basement, and the audio was fantastic. And it has been like that for the past four weeks. I have rediscovered the fun of SWLing and the DX stations that I have found on 31 and 25 meters just cause me to shake my head in amazement at times as to what a simple transistor circuit can achieve using just a couple of feet of wire as an antenna. Oh, and those receivers do a fine job for checking the activity on the ham bands when I'm upstairs in the study. I did make one contact today on 40 CW with another solid-state regen I built a few years ago and the secret there is to have separate sidetone monitoring and netting the receiver to the transmitter using very, very low power. I think a 2N2222 xtal osc circuit to serve as a marker with some of the QRP frequency xtals I have will do the trick in the future. So now I'm trying to decide whether to build the PipSqueak or the WBR special next. Anyone else on the list "suffering" with regen madness these days? 72 de Ted, AB8FJ ------------------------------ Date: Sat, 1 Nov 2003 19:29:37 -0700 From: "Rod N0RC" To: , "qrp-l" Subject: [160485] Re: For sale: DSW-40 and K1 Message-ID: <009d01c3a0e9$29a5ed30$6501a8c0@greyrock> MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit Why not Pat?

Personally, I prefer IBM. The price isn't all that much different and the quality, IMO, is a lot better. One of the issues, tho, is the pointer. Seems like each manufacturer uses only one kind of pointing device. A lot of people really hate the TrakPoint on IBM and Tishiba laptops, I personally like it. It's not that great for drawing, but when you're typing, it's right there. I really hate the little pads, a lot of people like them. I would suggest playing with the different machines at a Best Buy or something like that to find out what you like best before you buy. Keep in mind, too, that a laptop really isn't all that upgradeable. With a desktop you can upgrade disks, motherboards, video cards, CDs, and keep incrementally upgrading the same machine for years and years. With a laptop all you can really do is upgrade the disk, and that tends to be expensive. On a brand new laptop you might be ablt to add a CD writer or something like that, but the compatible device will no longer be available in a year or so. So keep in mind that the thing will probably be a boat anchor in 3 years or so. Even then, the battery probably has a 1 or 2 year life, and by the time you replace it, the battery will cost more than the laptop is worth. There's a tremendous amount of convenience to having a laptop, but they are a little more expensive than they appear at first glance. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Francis Callahan" To: "Low Power Amateur Radio Discussion" Sent: Sunday, November 02, 2003 10:37 AM Subject: Info on Buying Laptop > I am thinking of getting a laptop computer.

From RadioShack.com: "For travel or home. Clips over receiver's rod antenna. 23-ft. insulated wire stores on reel when not in use." I have a very similar antenna that came with a Sony shortwave radio a few years ago. It is 25' of wire, but reels up just like the R$ one does. Was just thinking that with a bit of a counterpoise, this antenna might be perfect with my new KX1 (#073). Nice and compact. Finger dimple to allow quick rollup. No pecuniary interest in R$ (wish they had had a frequent buyer program for the last 30 years, though...).

Are components by different manufacturers really directly interchangeable..or are there some slight differences.? If so ..how significant are the differences? Which components are SAFE to interchange and what are the ones you have to be careful with. I spoke to a technologist and acting engineer this weekend ..and he told me GATES ie NAND OR ect..are pretty well SAFE to interchange..but timing circuits are sometimes a bit tricky. I realize this is very general statement. I hope to build up a data base with much more specific information. Anyways. I hope to also have some interesting ham radio circuits.. ie QRP stuff as well and test jigs..hints and kinks ect. I will be posting some of the emails I have received from folks on the subject of electronics components. If you dont wish your email posted..please let me know.

Sitting on my workbench (among the other breadboards and projects in-work) is my latest effort at a regen (2N3904 common base RF amp, MPF102 regen detector, LM386 audio amp) and a homebrew active antenna with an 18 inch clip lead for the pickup. Both are built "Manhattan" style, my first projects built like that (and of course, I'm hooked on that construction technique now!). Both are in boxes (usually do this on plug-in breadboards) because they were far too much fun for just temporary use. The regen stage is sort of a Hartley with a few turn link, rather than a tapped coil, which is fed from a pot in the JFET source. Even added a bandspread tuning pot (a necessity on a receiver that tunes 9 to 19 MHz in a half turn of the knob!) which feeds voltage to a varicap diode. A "bandswitch" puts in an extra fixed cap to get to 49 and 40 meters. I spend at least a few minutes with it every week just to remind myself how well simple circuits can work. Yes, the sensitivity of a typical regen is amazing. I built some gain into the active antenna, but the first thing I found was that I had to add a "volume control" to it and crank it nearly all the way down so as not to overload the regen. It has trouble with strong signals but not with weak ones. For what's in them, these regens work much better than one would think. They separate stations and do a good job on CW and passably on SSB even. Was surprised at how well it handled the CW SS'ers on 40M last night. I must admit however that I've never even attempted a ham QSO with a regen receiver, because of worries about overload and drift. A good DC receiver can be nearly as simple and work better, but not for AM signals which is where the regen really shines. If you've played with simple superhets, where its easy to overload the IF amp and clip off all the audio on strong signals, you realize that somehow the regen detector performs an admirable AGC job too. I don't often sit and listen to SWBC, but I like to tune around and see what can be heard and how strongly its coming in. There are some rather interesting programs and music on the stations, and one can get sidetracked on a jaunt thru the bands. Radio Netherlands (when its broadcasting in English) can be hard to get past. These days, as often as not, the stations aren't transmitting from their home turf, so you don't always know where the signals are coming from. Radio Netherlands broadcasts from the Caribbean. The Voice of Greece booms in on 17 MHz; I believe its actually broadcast by Radio Canada, somewhere on the east coast of Canada. Regardless, SWLing is fun and there are a lot of things out there to hear. Using a regen receiver, especially one you have just built yourself, cranks the fun up another notch or two. Nearly lost my composure when I saw the receiver project in the latest QST! Talk about a fun looking receiver! Looking at the schematic takes me back to the days when you could pop out the IF tube in a receiver, wrap a short wire around the grid pin, run the wire up the outside of the glass envelope, then plug it back in. For those who have never done this, the feedback capacitance added between the plate and grid gave you a regenerative IF stage to boost the gain and selectivity. You could even make it oscillate as a BFO to receive CW and SSB. You just adjusted the position of the wire to get the amount of regeneration you wanted. Cool trick. The deluxe version added a pot in the cathode lead as a regeneration control. Regen may be outmoded for serious communications with today's technology, but I'll bet there are plenty of us experimenters still tuning the bands with them. 72's, Phil WB7AEI ------------------------------ Date: Sun, 2 Nov 2003 15:06:21 -0500 From: "Brian Murrey" To: , "Low Power Amateur Radio Discussion" Subject: [160521] Re: Possible KX1 field antenna on sale at RadioShack Message-ID: <008f01c3a17c$c95567a0$02fea8c0@bjmw2k> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Here's a neat idea for portable dipole.... http://www.eham.net/articles/5523 ----- Original Message ----- From: "Michael C.

The Compaq I purchased a few months ago has three (count them!) USB ports, but NO serial ports. I found a rather inexpensive "adapter" that will convert a USB port to RS-232 (see: http://www.sewelldev.com/USBtoSerial.asp ) that works GREAT, but I've discovered it produces a bit of RF hash in the VHF band (right around 144.200, unfortunately). I've not yet tried ferrite or anything to quiet that down, as it is not a problem on HF, which is where I spend 99.999% of my radio time.

I recently bought a used laptop and I'm tickled to death with it. It cost me less than a third of what a new laptop cost, and I'm pretty confident I'll get at least a third of the use out of it One big issue is the battery. Laptop batteries cost up to $200, with most being in the $100 neighborhood. This is a hard thing to check when you buy a used laptop, and it's a major reason why people trade in otherwise perfectly good laptops. These are usually Lithium Ion batteries anymore, so you can't just replace the cells like you can in an old NiCd battery. The other thing I failed to mention is ports. You said you wanted it for ham use, and so you will need ports. Look carefully, a lot of laptops are deficient in ports, or they need a docking station or port replicator to access them. There is precious little amateur software that works with the USB ports that are popular, and for many of these applications, the USB to serial adapter won't work, either. And don't be too stingy with the hard drive. You said you only wanted it for things that basically don't need storage. Recognize that a laptop is a terribly convenient thing, and it's hard not to use it most of the time for everything. You may find that your main computer will sort of fall by the wayside. Also, for many of the things you mentioned, you will need to be connected. For a laptop, you really loose a lot of the advantage if you need to be wired. Think about making a connection to whatever your home connection is over wireless. Again, it depends a bit on your sensitivity to price, but the kinds of things you mentioned will be just fine over the cheaper 802.11b, although a lot of folks will tell you that 802.11g is better. It is, but it's a lot pricier. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "sjolin" To: "Low Power Amateur Radio Discussion" Sent: Sunday, November 02, 2003 12:16 PM Subject: Re: Info on Buying Laptop > Given the use you plan for yours, I dont think I would buy a new one > as you probably dont need the speed, etc. ------------------------------ Date: Sun, 2 Nov 2003 22:09:30 +0100 From: "Sverre Holm" To: , "'Low Power Amateur Radio Discussion'" Subject: [160525] RE: Regen Receiver Fun Message-ID: <000f01c3a185$a75c9250$8e00a8c0@Master> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit > -----Original Message----- > On Behalf Of Ted Albert > > So now I'm trying to decide whether to build the PipSqueak or the WBR > special next. > > Anyone else on the list "suffering" with regen madness these days? I've had a lot of fun with the WBR receiver which I built Manhattan-style a few weeks ago. Although it doesn't match a good superhet, you get more performance per component than in any other receiver! The WBR is a regenerative receiver with good isolation from the antenna and with little interaction between tuning and regeneration controls. The WBR has a JFET detector and a separate oscillator for the regeneration, plus an LM386 audio amplifier. WBR = Wheatstone Bridge Regen, and that is the unique part of it, a sort of a balanced input circuit with very loose coupling to the antenna for minimizing radiation Unlike other regens I have tried, it is stable enough to listen to CW/SSB. Mine covers from 7.0 to almost 7.3 MHz, and I also use it for listening to broadcasts. Of course, I just had to make some 'improvements' so I have modified the original design slightly by adding more audio gain (NPN transistor between JFET and LM386) and an audio gain control. Maybe the next project should be a superregenerative? I wonder if there is a 'modernized' superregen design around, say for 2 meter? -- 73, Sverre ------------------ Sverre Holm, LA3ZA www.qsl.net/la3za ------------------------------ Date: Sun, 2 Nov 2003 16:27:42 -0500 (EST) From: "n2cx" To: qrp-l@lehigh.edu Cc: njqrp@njqrp.org Subject: [160526] PAC-12 and Tenna Dipper - long, biased Message-ID: <200311022127.hA2LRgdO020685@email2.voicenet.com> MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Group, I was fortunate to be in on the ground floor so to speak with James Bennett s (KA5DVS) neat PAC-12 antenna. Several years ago he brought his first prototype out to QRP To The Field. Its small size and clever construction impressed everyone there. I encouraged James to write it up and so he did! The article appeared in the QRP Homebrewer and proved so popular that James allowed us to post the info on the NJQRP web site for all to enjoy. Needless to say I duplicated it post haste and found it much to my liking. Much as James, I travel frequently on business and need a small antenna that can be packed in my luggage and set up nearly anywhere. Since it breaks down into 12 inch pieces it tucks away in almost any suitcase. Fast forward a couple of years - James has now gone commercial! He has a web site under pacificantenna.com with the details. Suffice it to say that it is basically the same design, polished a bit and including machined parts that take away the need for exotic tools. All you have to do is wind the loading coil and screw it together. James was kind enough to include me in the beta test group. I had mine built in record time and used it effectively in This year s QTTF. While not as effective as a tri-bander at 60 feet, it managed to snag 40 meter contacts all over the East coast and 20 meter Q s out to New Mexico. Since then I ve used it by necessity at the home QTH. My fixed antenna was taken down as a preventative measure During hurricane season and I ve not decided what its replacement will be. So the PAC-12 is the interim home antenna. It seems to do quite well for my casual operation. I ve done a couple of things to enhance its operation. The first is to mount it on a 3 foot high metal fence . This gives it mechanical stability and adds to the ground plane. I ve also added six 15 foot radials to the ground system. The basic set of radials included with the kit work pretty well for 20 meters and up but more ground is needed for stable operation on 30 and 40. Incidentally you can gauge if you need more radials by noting SWR readings at the far end of you feedline. If touching the shield of the coax or the SWR meter case changes the SWR, your feedline is acting as part of the ground system. While the antenna will work, its operation may be affected by cable placement and body proximity. Just add more radials as I ve done and things settle down. Yet another find is the KD1JV Tenna Dipper! This thing was a absolutely *made* for portable antennas and is a great adjunct to the PAC-12. Mine is installed in a Whitman s Sampler tin and goes everywhere with the PAC-12. It makes adjustment to resonance painless. Be sure to order one from the Four States QRP Group ASAP. You will not be disappointed. See http://www.w0ch.net/fsqrp/kits/kits.htm for details. Steve Melt Solder the recent recipient of the NORCAL QRP Contributor of the Year has graciously allowed that new club to offer his kit to support their operations. While the PAC-12 and the Tenna Dipper are not the ultimate in performance they are a convenient way to quickly and inexpensively get on the air to make lots of contacts when it is difficult to use a more traditional antenna. Please check them out! Now I m not a paid employee or any other such blather. I am a sort of insider being friends with the folks involved and having been a PAC-12 beta tester. My main reward is being able to share my positive results to encourage others to use this pair of worthwhile products. 72/73, Joe E., N2CX ------------------------------ Date: Sun, 02 Nov 2003 16:43:51 -0500 From: "Henry Freedenberg" To: qrp-l@Lehigh.EDU, "John J.

About a year ago I got a hankering for a laptop and purchased a Toshiba 233 MMX for $240. It has 232, USB and infra-red. The battery was dead so I found a replacement on ebay for $25 (there are people who rebuild laptop batteries..the one I purchased lasts for about a.5 hours and is fine for my needs. I didn't like the 4GB HD. I upgraded the W98 OS to recognize a large HD and purchased a 20GB HD on ebay for $85. Works fine. Also bought network cards (have both ethernet and 11g). Both work fine. Went to Eckerds and bought an AT&T prepaid internet access card for $10 (2 hours on 800 number or 8 hours on local access number...have ever been anywhere where I had to use the 800 number). Bought the $30 Digi-Traveler GPS. Also bought inverter for car and various cables. I have about 40% of the cost of a new machine invested. The 233 is fine for traveling..surfing, word processing/report preparation (my math modeling software for the day job runs fine), data logging, running the GPS etc. I figure that I have about $400-500 invested and it is one of my more worthwhile purchases. What I would do differently...the AC inverter makes lots of RF hash...will check into the N4UAU(?) DC-DC converter. The laptop screen is TFT(?) and washes out easily in daylight. I would look for a unit with an easier to view screen. Also, the Toshiba has a pencil eraser type thing that passes for a mouse. Very difficult to use in the car. I would look for a unit with a touch pad. my partial workaround for the mouse problem consisted of going into the control panel and setting the maximum trail time and minimum speed for the mouse. I am toying with putting a dedicated PC in the vehicle. The new mini-itx boards seem promising. Haven't really thought this through yet...I found a promising video display for a reasonable price (http://www.ssl-hk.com/index_online.html) and would use and infrared keyboard/mouse. The problems are having to wait for a bootup whenever the car is started and I worry about the hardiness of things like the HD. It might be easier to just put a laptop in the vehicle. Meanwhile, I anxiously await John's PIC tutorials.... Henry On 2 Nov 2003 at 15:17, John J.

Very pleased with it.......However, several vendors offer the same technology. The Centrino stuff really gets the most out of your battery and offers built-in wireless. If you are going to use your laptop as a desktop replacement and are not conerned with battery time........you can save some dollars and opt for one of the Intel Pentium IV mobile processors or Celeron units....they generate more heat and drain a battery much faster, but it doesn't matter if you are running off the AC adaptor. You will find today's notebooks (no longer called laptops because they can get pretty hot and burn your leg if you have it sitting on your lap) fall mostly into two catagories.......the "desktop replacements" and those that are used by the road warriors....the mobile-minded folks that really need good battery life.

Has *only* a ten gig hard drive, 400MHz PII processor, 128MB ram, 56K modem... Has Legacy printer and serial ports (and PCMCIA slots, of course) for connectivity with my simple homebrew projects plus apps such as DigiPan, MMTTY etc. USB port for...well, for USB connectivity. Small footprint on the project/operating bench. Just purchased a 'mobile' DC-DC power converter...10-14 VDC in....12-18 VDC out in discrete steps...great for running the TP from a 'car' or 'deep-cycle marine' battery... It's all I currently need to stay connected......got it for pennies on the dollar at 'you-know-where"... There ARE much newer (and much more expensive) models floating around out there...with varying degrees of connectivity. YMMV...kinda depends on what your current and future needs might be... 73.
