The manual states that the audio amplifier circuit is optimized for a pitch of 600-650 Hz. I set my offset to 400 Hz and have no problems. I don't know about the mod to increase bandwidth. I did install a 10-turn pot and am very glad I did. One other thing. I wound the VFO inductor L9 as per the instructions, but during alignment had to add a turn, so I'd suggest building it with an extra turn (61 turns total), as it's easier to remove them than add them. It is a sweet radio, and I'm sure you will enjoy it. Good luck. By the way, I bought the book, as well, but got impatient, built the radio, and have yet to read the book. I'm hoping to get to it soon. :-) Best, Andy N1KSN Menasha, WI ------------------------------ Date: Thu, 27 Nov 2003 19:42:35 -0500 From: "Tim Jones" To: "Low Power Amateur Radio Discussion" Subject: [161963] RE: New Kit Announcement - Brass Paddle Kit Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Is there a link to the webpage?

The first symptom was that it would not boot up on the first turn-on but after three or four tries it came up and ran normally. A few days of the above, and it would not boot even with multiple tries. Questions: 1. Would a dead lithium battery on the mother board act like this? 2. Has anyone had experience replacing this battery? If so, how do you get to it. 3. After replacing the battery what sort of start-up problem should I expect? As is obvious from the above, a computer genius I ain't.

Inital results look good. The digital display tracks the analog meter on the WM-2 very closely on all ranges. That means the output from the diode compensation amp is very linear, all the way down to milliwatt levels. I did have some trouble getting the readings on the WM-2 meter to agree with my true rms digital watt meter. I had to cobble together an adjustable output, AGC output level stabilized, linear amplifier capable of at least 10 watts output which produced a good sine wave in order to get the two meters to agree. The WM-2, like most watt meter designs, requires a perfict sine wave signal to read accurately. This is something to keep in mind, as assuming a perfict sine wave is coming out of your rig maybe a poor assumption to make. I still have some clean up work to do on the software and monkey with the display formate some, then add a SWR calculation routine. When it's finally done, the software will become available for free down load. 72, Steve, KD1JV "Melt Solder" White Mountains of New Hampshire http://www.qsl.net/kd1jv/ ------------------------------ Date: Tue, 25 Nov 2003 14:46:12 -0500 From: Steven Weber To: qrp-l@lehigh.edu Subject: [161966] Silk Screening info?

Too bad I never got a chance to learn how to do it - we always had cute young girls just out of art school for that job :-) Anyway, I'd like to print the top of the new AT Sprint box. I can have it done locally, but I figure for what it would cost, I could buy the stuff needed and do it myself. I've found some suppliers on the web, but not quite sure what I need to buy, besides the obvious. A basic set up doesn't look too expensive.

Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit When I was in Boy Scouts, I did some silk screening... it was a MESS! basically, you need a screen, silk is good since it is thin and strong, it must be stretched TIGHT on a frame. Take you stencil and lay it on a piece of scrap material, lay your screen over the stencil, and squegee (I cannot spell it tonight... err, this morning!) but you lay the silkscreen ink across the frame. The ink will hold the stencil to the frame after the first pass. You want that ink to to be the thinest possible so that the ink dries fastest and doesnt smudge. In scouts, I had help... my neighbor worked for VelvaSheen - I think that they have since gone out of business, at least I have not seen any VelvaSheen products in MANY years. We made t-shirts for the troop and shirts for the RV club... I would ASSUME that the process is the same for circuit boards too.

In fact, many people have suggested such a change in my design. The use of analog needle panel meters would also have similar benefits in other projects I build. The advantages: 1. Eliminate the need for the LM3914, LM3915, 20 LEDs, and 2 PC boards. 2. Save space inside the chassis (by eliminating 2 PC boards). 3. Save space on the front panel (by eliminating 20 LEDs). 4. Save time building the device as a result of factors 1, 2, and 3. 5. Better readability in bright sunlight My questions: 1. Where can you buy analog needle panel meters for a cheap price? They seem to be in limited supply and expensive (many are over $100, some well over $100). 2. Are there any panel meters with shafts 7/8 of an inch wide or smaller? I ask because my Unibit only goes up to 7/8 inch. 3. If the answer to question 2 is no, how do I drill a larger hole cleanly and neatly? I do have a Nibbler tool, but I think the edges of the holes would be even messier than those of a regular drill. 4. Are there panel meters that can give you voltage 2 as a percentage of voltage 1? Measuring the reflected voltage sample as a percentage of the forward voltage sample would be necessary to determine the SWR.

Message-ID: <20031128172126.61740.qmail@web11608.mail.yahoo.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Hey guys! I'm thinking about putting together a 40meter ground plane vertical with the base about 16 to 20ft up. I thought if I made the vertical heavy enuff ( 1 1/2" to 1" aluminum tubing?) I could mount an 88' on a side doublet on top, feed it with 450 ohm ribbon, and use it pretty well on 40/80/160. I'm also thinking I'd feed the ground plane with 450 ohm ribbon and probably be able to use it on 40 & 80 both. This should be an improvement over my current 44' on a side doublet up about 35 ft and also give me a chance to do some extensive comparisons of dipoles vs verticals. My question? How should I run the feedline for the doublet to minimize interaction AND is there going to be so much interaction between the two antennas that my vert vs dipole comparisons aren't valid anyway? Thanks for any advice! 73, Gary ===== Gary Slagel/N0SXX Conifer, CO http://gdslagel.bravepages.com __________________________________ Do you Yahoo!?

Yep. It actually sets the temperature. There's a bimetal/magnetic thermostat control in the barrel that controls the temperature based on the thickness of the little nub on the back of the tip. > i pulled the tip out of mine, and it has a "7" marked on the bottom.. > > does this mean 700F?

I believe tips are available for 600, 700, and 800 degrees F. The WTCPT was my first real soldering station, too, and I now wonder how I did without it. It makes soldering small components much easier and less anxiety-producing. By the way, I have used 700 degree tips exclusively with great results. Now, for soldering coax connectors and other large mass components, you will probably need a hotter tip (I still use my almost 50-yr old Wen soldering gun for PL-259's--otherwise, it is officially retired from electronic projects).

However, perhaps you can place a long(er) insulated extension at the top of the vertical (where, by the way, there is a voltage node), and then put the dipole attachment point atop that section. Food for thought. Let us know how you do.

Hey guys! I'm thinking about putting together a 40meter ground plane vertical with the base about 16 to 20ft up. I thought if I made the vertical heavy enuff ( 1 1/2" to 1" aluminum tubing?) I could mount an 88' on a side doublet on top, feed it with 450 ohm ribbon, and use it pretty well on 40/80/160. I'm also thinking I'd feed the ground plane with 450 ohm ribbon and probably be able to use it on 40 & 80 both. This should be an improvement over my current 44' on a side doublet up about 35 ft and also give me a chance to do some extensive comparisons of dipoles vs verticals. My question? How should I run the feedline for the doublet to minimize interaction AND is there going to be so much interaction between the two antennas that my vert vs dipole comparisons aren't valid anyway?

Yes, as other have pointed out. The temp is adjusted by the material INTERNAL to the tip. A tip stamped '7' will be magnetic below 700 degrees, and non-magnetic above 700. One other thing... Genuine tips for this iron are 'plated'. They are extremely durable, but you have to take care of them. When you first heat a tip, coat it with solder. When you go to use it, wipe it on the damp (not wet) sponge, and freshly coat it with solder again. NEVER EVER EVER abrade the tip. NEVER file it, never sand it, never rub it! EVER!! When you are done using it, before turning off the iron, wipe it on the sponge to clean it, then apply solder again to coat it. Let it burn off any flux until the smoking stops, then turn the iron off with the tip STILL COVERED with fresh solder. This will protect the tip from corrosion. Treat it right! And it will last for years of hobby use. MANY years! Mike ------------------------------ End of QRP-L Digest 3118 ************************ --------------------------------
