The Brenda JamFest is up and running full speed ahead and to top that off a few other things have happened..... I got my ScQRPion Paddle kit yesterday and guess what??? It's number 007.... Wheeeeeee. Many many thanks to whoever passed out the numbers. Sometimes a fellow gets lucky! And that same evening the UPS truck found us and dropped off a copy or two of a new booklet published by the QRP ARCI. It's my little "How to Achieve 20 WPM CW with NO Effort on Your Part, Or I'm Lazy and Don't Want to Work at It! Check with Hank at the QRP ARCI Toy Store to find out how to get one. I don't know the price..... Hey, I just wrote it! :-) Then there was the phone call about a project that I'm being offered that would put me in Australia next spring! So it's a very busy week and I'll know more after next weeks meetings.....

I wanted to see how I had done with my 5w, K2 and WimpyWire vertical. I looked for the CA scores, and found them on p. 105. I found I had taken first place QRP in CA. Considering the handicap of operating from the west coast, I thought this was pretty good. Then being curious, I wondered if I had beaten any QRPers in other states/provinces. Digging through the scores I found I had beaten the entered scores of QRPers in 14 states/provinces--CT, ME, NJ, NY, MD, GA, NV, WA, MI, WV, CO, IA, VE2, VE7. To be fair, I checked on how many state/province entries had beaten me. There were 10--MA, NC, VA, AZ, UT, OH, IL MN, MO, VE3. This didn't seem like a very long list, so I checked for states/provinces with no QRP entries. There were 29--NH, RI, VT, DE, PA, AL, FL, KY, SC, TN, AR, LA, MS, NM, OK, TX, ID, MT, OR, WY, IN, WI, KS, SD, VO1, VY1, VE5, VE6, VE9. I'm sure there were QRPers in the contest who just did it for the fun, and never entered their scores. Ok, now I'm really getting greedy. Did I beat the top Low Power station in any state/ province? Turns out there were 8--CT, MA, RI, AR, ID, WY, VE5, VE6. Wow, QRP Lives! Ok, what has this proved? Not a darned thing, really, other than that QRP is a lot of fun and can turn in surprising results in contests. But then, you already knew that, didn't you? 73, Bob N6WG ------------------------------ Date: Tue, 09 Dec 2003 19:36:47 -0500 From: Peter Burbank To: "Low Power Amateur Radio Discussion" Subject: [162653] Re: LAB, Sulfated plates.

The stuff that Wal mart sells is the same chemical to the best of my knowledge. I read a review in Car and Driver a few years ago and they concluded that VX-7 was one of the best additives for an auto.

The handbook gives the formula, L(in uH) = (d^2*n^2)/(18d + 40L), where d is the diameter of the coil (C to C of wire), n is the number of turns, and L is the coil length in inches. I guess you could also d is the diameter of the form plus the diameter of the wire. ('L' refers to the second 'L', since lower case l just looks too much like a one.) Assuming your wire size and coil form size fix 'd', you still have variables d and L to contend with. I'd put the formula into a spreadsheet or calculator and play with numbers until you hit a good combination. But that's for and *air core* coil, right? Yes. I think I've heard that it's good practice to design so that the slug just enters the coil a little bit at the correct inductance value. I suppose this is to give maximum Q and also to help with temperature stability, which will be better with "mostly air" than with "mostly iron powder" in the coil. So I'd recommend designing for maybe 3.5 or 4 uH as an air core coil and then let the slug shim it up the rest of the way. 72 and give us a report-- Nick, WA5BDU -----Original Message----- From: owner-qrp-l@Lehigh.EDU [mailto:owner-qrp-l@Lehigh.EDU] On Behalf Of Rod N0RC Sent: Monday, December 08, 2003 5:41 PM To: Low Power Amateur Radio Discussion Subject: [qrp-l] Slug tuned coil winding question.

Why did they pick any on-air frequency? Because it's all supposed to stay inside the cable and/or the cable is supposed to be totally shielded from outside influences. He had it right on - ingress! There ain't supposed to be any. If there is, there's also egress, which is leakage, which we ain't supposed to have either - in fact, it's strictly FCC regulated. Otherwise we'd be interfering with air navigation, communications, and all kinds of things and maybe bringing planes down on our heads. I speak as one who has been working for Time Warner (Milwaukee) via a contracting company for 2 years, and is now training as an in-house employee (Broadband Tech I). In my training group are three new guys in the CLI department - guys whose only job is to drive the 3000+ miles of cable plant and find leaks. They have to drive all 3000 miles of plant every 3 months. The lower range is used for the return path for cable modems and fancy cable boxes - that is, frequencies below channel 2, circa 54 MHz. Thanks to hamming, I'm ahead of most guys on splitter losses, coax properties (the trainer couldn't even define characteristic impedance of coax very well), return loss, shielding, et al.

Of course, the key is: are they really from Yahoo, or is it folks using them (and other biggies) as a spoofed return address? My own domain is even used as a spam return address - and they're even dumb enough to send some to me so I can get wise and make a (feeble) attempt to complain. The best anti-spam approaches actually check the IP address of the sending server, not just the domain name. - a program like MailWasher, for example, checks sources like Spamcop that work only on IP addresses. Putting a whole domain like yahoo into your "spam" is about like rejecting all calls from a certain area code just because you get lots of telemarketing calls from that area.

Hey John; Actually reverse address checks are not fool-proof either. In fact alot of legitimate mail would fail such a test. There are examples galor, including everyone that gets mail thru an email forwarder. The only sane way for the internet community to handle spam is to disallow mail relays by checking outgoing mail for address headers that indicate this on the (supposedly) very first smtp hop, and not trashing any mail, but rather tagging it for the end user to process in a local email client. Any email forwarders should also have spam tagging (and tagging only i.e. no dumping) software installed as well. Anything else will not be correct at least a real and measurable percentage of the time IMnsHO. And now that the congress has gotten into the act, you can bet it will be all screwed up. ...........................

Pretty heavy QSB........K5TR finally popped out of the noise after disappearing a few times. Never even heard W8RU but there might be a connection between that and the huge cold front rolling in here or perhaps the skip was long. 73 Pete NV4V Kentucky ------------------------------ Date: Tue, 9 Dec 2003 23:42:08 -0500 From: "Tom Palmer" To: Subject: [162690] FOX: What an evening Message-ID: <000501c3bed7$f87ea000$4f3b0843@swfla.rr.com> MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit If - as appears to be true - W5YR, George, did not bag both pelts this hunt, no Hound will be "14 for 14" when the Week 7 LOGS are posted. George will be "13 for 14." Not too bad, though. Being "40 for 40" at the end of the Winter Season is a real accomplishment. Very few hounds have ever accomplished "40 for 40." George (in TEXAS) was loud here in Naples, Florida, throughout the hunt. I could hear Ron, W8RU (in Michigan), up until 0400 but there was heavy, slow QSB on Ron's signal during the 2nd hour. Heard N4ROA and N9AW calling Ron and both were loud here. Ron came back to Dan (in Virginia) at 0348, but I didn't hear Ron give Dan a pelt. Didn't hear Ron go back to N9AW. Heard Doc, K0EVZ, bag his pelt from Ron with only 1 call. Nice grab! Doc. Band conditrons this hunt were bad, but on 1 or 2 occasions I've heard worse.

I had a few problems that resulted in a shaky start but I got most of them worked out during the hunt. The cold front is blowing through here and the wind is/was gusting to 40 mph and stirring up one or two bad connections on the power lines tonight. But the noise was not on all the time and not too bad. As everyone has noted the band was long but did seem to change some near the end when I worked several stations in NM and CO with big signals. I thought I heard W5YR at least once but he was very weak. I hope my signal was OK out there and congrats to W9JOP who made it into the log with 50mW if I copied it correctly. And if I got it wrong I am certain he was running some sort of mWatts.

Thanks much for your note, Ron. I heard faint snatches of your signal right at the start of the Hunt and then you just vanished. I was about ready to shut it down when I checked your frequency once more and faintly heard you. I took a chance and called and heard you come back with my call and your exchange. Just as I started mine, a QRO station came on calling CQ, so I figured I was wiped out. That is why I repeated the exchange and "hoped." I faintly heard an "R" when I finished and then you vanished again. What an evening! Thanks again for the prompt confirmation, Ron, and for taking the time and effort to be a Fox for us. 73, George W5YR w5yr@att.net ----- Original Message ----- From: "Ron Majewski" To: Sent: Tuesday, December 09, 2003 10:44 PM Subject: you made it! > Hi George, > > Yes, you're in the log at 0343utc.

See for pics of the close-spaced-fingerpieces mod. The link to keys and paddles is at the lower right on the main page. Then again on the lower right of the next page for the link to these photos. I considered originally using countersunk screws, but feared weakening the plastic at that point.

The TTFD in even its original version with a 390 or 400 ohm terminating resistor, and using the formula 100/lowest frequency of operation for calculating the length of the antenna, and 3/ lowest frequency of operation for the separation between wires, is a COMPROMISE antenna system,very useful for some specific applications.... The mucho mas modern .... yes, much more modern design ( computer optimized ...) with a 800 to 900 ohm terminating resistor and even less separation between the upper and lower wires works very well and you can see all the data at www.cebik.com , if you don't believe me. I ran a lot of tests, not only with different antenna modeling software, but also in actual practice, and all I can say is that the up to date design of the T2FD is a very useful one for many applications... One must admit that on frequencies where the antenna is less than 1/2 of a wavelength long, it will be introducing expected losses...but, that's a small price to pay for a single downlead, a single antenna and a really wide coverage, plus the fact that your T2FD will in many instances fit where other antennas for the lowest planned operating frequencies won't !!! My 14 meters long ( about 44 feet ) T2FD with separation of 30 centimeters ( 12 inches ) between the two wires, 820 ohms 20 watts non inductive terminating resistor and a homebrew 12 to 1 balun works extremely well from 30 meters up, and provides a nice 40 meters band antenna that may perhaps be about one S unit, or maybe less than one S unit down from a full size half wave single band 7 mHz dipole... I do use the TTFD or T2FD a lot for scanning the bands, and also for short wave listening... it is a nice looking antenna, costs little to homebrew, and connected to the antenna tuner all my radios like it.. Without the antenna tuner, the maximum SWR I see is about 2.5 to 1 on some specific frequencies, and my vacuum tube radios finals can take it easily... On many frequencies the SWR is much less so I can carefully connect my solid state radios to it, watching the SWR !!! Although some antenna gurus will object to this statement , my perception is that the TTFD picks up much less noise than my half wave wire dipoles, my EDZ and of course my verticals !!! 72 and DX YOur friend in Havana Arnie Coro CO2KK ----- Original Message ----- From: To: "Low Power Amateur Radio Discussion" Sent: Tuesday, December 09, 2003 11:06 PM Subject: Antenna (and 50 dB issue) > I ran a series of EZNEC models and unable to get more than 12 dBi variation > with a wide range of antennas without directors or reflectors.

In review of my previous comments on the T2FD from a few years ago I agree the T2FD has a lot of merits and even with the -16dBi on 160m you are looking at only about 2 S-units reduction. Even more crutial in many instances is the generated lobe pattern. Understanding the pattern and the expected gain one can have reasonable expectations from a particular antenna. As is with all antennas, they are a compromise, especially with multiband antennas....you just can't have your cake and eat it too. Again you raised some very valid points regarding not only the T2FD but antennas in general. Regarding the earlier issue of the 17ft vertical with a 45ft horizontal wire I have found thru both calculations and experimentation that you get an optimum match in most cases when the horizontal and vertical legs of an Inverted-L are similar in length. For 160m I have found a 33 by 33ft inverted-L is minimal in size for a marginally effective antenna with resonable impedance characteristics when fed with 300 ohm line. With the 17 by 45ft set up it is actuall adventageous to add a coil to the top of the 17ft vertical wire and shorten the horizontal wire to about 33ft. The coil is about 50-70 turns on 1 inch pvc form to cover 160-10m and 30-50 turns for 80-10m. this gets the loading generally within the range of most auto tuners. Thanks for the feedback and for those not familiar with the past comments and criticisms on the T2FD do a GOOGLE search in the GROUPS section and you will get a long list of past posts. You will get to see both pro and con feedback.

My wild idea is to give the fall/winter fox the capability to operate on both 40 and 80 meters changing bands however they want. This would make things more interesting for those within the 40m skip zone, but offer more range (to those foxes who don't have phased verticals) than only operating on 80m. and anticipating/looking for the bandswitches adds to the hunt when we can only hear them on one band! to keep things on even keel - rule would be one qso for hunters to not reduce number of calls in the log. Just an idea -- we got to use our heads as we deal with a less robust ionosphere. maybe this idea has to wait until next year for consideration, or we select a pair of foxes to give the idea a try. curt wb8yyy ocassional fox chaser --- Lloyd Lachow wrote: > > --- "George, W5YR" wrote: > > Absolutely the worst conditions tonight that I > have > > ever heard in a Fox > > Hunt, Obviously, the Truffle was non-existent > here. > > > The amazing thing is, here in MD, all seemed fine > until about 0220 or so - then the RF-impermeable > curtain drifted down. > > LL > > ===== > 73, 72 es oo, Lloyd, K3ESE - Reisterstown, Maryland > KX1#11 - multiPIG+#14 - K1#379 - 20/40M RockMites > > EDZ - Longwahr - Begali Magnetic Classic Paddles > ARRL - ARS - QRParci - QCWA - FISTS #8774 > FPQRP #476 - QRP-L - BORG #2 > Fun = Skill / Power ! 8^D > > __________________________________ > Do you Yahoo!? > New Yahoo!

It was really stiff and not very useful. If you loose your spring, you can buy another 6 (actually 12 since we cut the spring in half) at the local hardware store. Look for a display rack of Century Spring. The springs will be in a little plastic bag. Look for spring C-516. A small bag will cost about $2.50. There should be six 1 inch long springs. You can cut one in half and have the same spring as we provide. If you want a slighly stiffer spring, cut the spring longer. Cut it about 3/4 inch or so and then try it out. You can always cut more off. If you can't buy any at your local hardware store, we will sell you two 1 inch springs for $1 + an SASE.

In those applications where SWR bandwidth is the defining goal at the expense of efficiency, it is a very effective antenna system. It seems to me, however, that the prime consideration in the design and implementation of any antenna should be its radiation capabilities: pattern in three dimensions, "gain" if any, and efficiency (inherent losses in loading coils, terminating resistors, traps, etc.). I think that too much emphasis is placed on how well an antenna "matches" or how well it covers a wide frequency range without any equipment or antenna adjustments. The trade-off here is convenience for efficiency. In some applications, it is justified - in others it is not. I guess it all gets back to the old urban myth that a low SWR makes a good antenna. The role of the antenna is to radiate and to gather energy from passing electromagnetic waves. How it is fed is an engineering issue dealing largely with cost, efficiency and convenience. I read post after post about antennas of various types and it seems that always the primary attribute being mentioned is how well they match. This is probably due to our predilection to use either 50-ohm coax or ladderline of some sort. Within reason, any antenna driving point impedance can be matched to any reasonable transmission line and still have the majority of the available transmitter power delivered and radiated. So, why not emphasize radiation efficiency rather than matching convenience? Some antennas employ matching at the feedpoint - this is most common with Yagi and driven array antennas with gamma, beta, T and other such matching devices. Others, such as resonant dipoles, rely upon pruning the antenna length, and perhaps the feedline as well, to obtain a workable line input impedance in the near vicinity of the operating frequency. Still others - notably the multiband antennas - use various methods such as stubs or traps to provide a match to 50 ohm coax, for example, or rely upon a low-loss line, such as ladderline, and a tuner in the shack to provide the impedance transformation required. In all these situations, I feel that primary emphasis should be placed upon the antenna configuration that provides the radiation performance the operator desires. Once an antenna has been chosen with that in mind, then matching becomes a secondary exercise that is usually resolved by any of several well-known means. For example, I use a pair of 20-meter Extended Double Zepp antennas on 80 - 10 meters. I chose this antenna for its gain on 20 meters and pattern applicability on those bands. The price was a widely varying driving point impedance from band to band since the antenna is not resonant in any amateur band. Fed with ladderline, the antenna is readily tuned with a convenient tuner in the shack Antenna performance first - matching second. Alan, I am not taking issue with your posting but it seems to me that "you get an optimum match in most cases when the horizontal and vertical legs of an Inverted-L are similar in length . . ." should not be the implied criterion for antenna design. Matching in some cases is primary, as in the case of a resonant dipole fed with coax and used within a narrow frequency range, and is the goal in the system design since the dipole is known to have certain given performance parameters. However, I feel that we should seriously consider the trade-off between antenna performance and the effort required to match to a desired feedline. Not yanking your chain, Alan, just trying to offer another viewpoint. Having the most effective antenna in the world is of little use if you can't get power to it, so matching is certainly a major consideration. My only point is that it should be secondary rather than primary in the list of requirements. Keep up the good work! Very interesting data and information. 73, George W5YR w5yr@att.net ----- Original Message ----- From: To: "Low Power Amateur Radio Discussion" Sent: Wednesday, December 10, 2003 9:39 AM Subject: Re: Antenna (and 50 dB issue) > Arnie > By infamous I am reflecting the general tone of comments about the antenna on > the various reflector.

Beside the groups of non ham hunters using two meter HT's, there seams to be some type of beacons on various freg between 144 and 144.5. The pulse rate is repetitive and each freg has a different pulse rate on it. There is also no CW ID sent from the beacons. I am assuming the beacon transmissions are from a type of animal tracking system used here in the wilds of the West Virginia Mountains. Does anyone in the group have any information about the tracking systems? Am I listening to what I think I am listening to.

If you can use a full size 3 element beam for 80 meters, so use it.

At the risk of giving it the kiss of death, I think this is a great idea. Maybe even split the hunt into 1 hour 40M and 1 hour 80M, or have one Fox on 40 and one on 80, and then they swap at the 1 hour point. I think that not only would this give those inside the 40M "skip zone" a shot, but it would utilize 80M CW which is somewhat under utilized. It is one of the first bands the Phone Phreaks point to when justifying expansion of the phone bands.

The QRN on 40m was low but so were the signal levels. I started with the yagi pointing East but only heard stations from the West. The rate meter quickly climbed to 70 and I settled in hoping for a big first hour. This was not to be. At 0220utc propagation took a dive. Everyone disappeared. I couldn't hear any signals for 3kc on either side of me. Definitely a bad thing. >From that point on the band was up and down. Hounds showed up in small bunches with large gaps in between.

I'm picking the same thing up on that rig, however I've observed that the signals drastically vary in strength around different parts of town. Perhaps it's a harmonic to some sort of control signal in the ~72 MHz band. I've not bothered to check that out. Anyone know who's spectrum slot that is?

My wild idea is As a Fox it sounds interesting. But let's make it a voluntery thing. My last Fox outing for instance was too many Hounds to work at first and then the band died and nothing much happened. I have an 88 foot dipole I use on 80 meters and 75 meters as net control for a local net. I have not listened to 80 meters at 0330 UTC but will do so soon. There is a heck of a lot of space down there! So as a strawman rule: The Fox may announce in his message to the QRP-L list that at a time after 0329 UTC he/she intends to move to 3.5040 MHz, and listen 2 KHz higher. This will perhaps allow closer stations to work the Fox. If others can be around at about 0330 UTC on 3.5040 MHz in the next few days let's see how well this will work. It's possible 3.5040 is not a good frequency. I will see this evening and might suggest another. > to give the fall/winter fox the capability to operate > on both 40 and 80 meters changing bands however they > want.

I've got a couple of boatanchors that I've mostly been using the straight key with, but occasionally would like to use my keyers with. I've done the in-line relay thing, to isolate the solid-state (2n3906?) from the 80v at the rig's key jack, but have found that there's a speed-limit on the relay. Is it possible to do a solid state solution using just diode(s) forward-biased in series with the keyer? That way the the voltage across the PN junctions of all devices would be divided. Correct??? I know there's switching times to these devices, but it's got to be faster than the relay I've been using (limits me to 30wpm).

As I mentioned before, this would give me the push I need to become QRV on 80. The Hunt already gives us a fun reason to improve our operating skills, and something along these lines might give more of us a reason to expand to 80, if not there already. Those of us with monobanders can feel justified in building a new rig, or two, maybe a new tuner...and...hanging more wire/aluminum, and... LL __________________________________ Do you Yahoo!?

Coax to the LDG balun was fine, but my son had gotten angry at me and had=20 shorted out the 450 ohm line across the balun terminals. I was loading just the shorted balun.

Last night I got one or two brief moments when I heard my neighbor in Detroit, but did not work him (I'm near Cleveland). At the same time that the hunt began I normally check into the 80 MI QRP net, and last night I heard none of that net; normally many stations there are 599 copy. A couple years ago in the winter hunts I could just about be assured of working both foxes if I waited the whole 2 hours, during that period I would get an opening. Not so this year. So I'm not sure 80 is the answer entirely, but it would be interesting to try out. We used to have two hunts a week, Tuesdays and Thursdays. I would myself like to see each fox on twice, once on each band, and you can only count at most one time working them. That would tend to even out location I think. Maybe list things several ways, 40 only, 80 only, 40/80 count all, 40/80 count one. But two things to remember, (1) its all for fun, and (2) band conditions, weather, and everything else are part of the hunt. Should we try to level the playing field (outlaw more than 2 elements in a beam for example)? Should we try to maximize everyone's success? When band conditions are really poor, I would love to have early spots on frequency posted here. I have had a lot of fun with the hunts, gained some useful skills, and learned much about propogation; two hours of tuning the radio and listening to noise can be a bit frustrating. 73/72 - Mike WA8BXN ------------------------------ Date: Wed, 10 Dec 2003 20:21:20 -0000 From: "Dennis Ponsness" To: "cw_list" , "QRPL All Members" , Subject: [162744] New Morse code character Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Looks like we will be needing to learn a new character now.

I think they would be able to handle 80v easily as they are rated for 100v. Not sure of the type of keyer that you are using, but you may be able to use one of these as "drivers" from your keyer to your BA rig.

Bandchanges occur all the time in contests and dx operations - and the fox is trying to maximize his/her score. I would suggest let the fox move between bands however they wish. They can announce QSY 80 and then move ... I was thinking only one pelt per fox - so no incentive to work both bands - as this reduces number of unique calls in the log. By the way, I get no competitive advantage from this as i have poor antenna characteristics below 40m as my wire is too low (until i choose to install some "artificial trees" which may not happen). The goal i have is to get more stations into the game, so if they are too close on 40m they will have a shot on 80m (if they find the fox there when they are looking). We may limit the number of band changes during the event, maybe 5 or 6 is a good number? Or we could just split 1 hour of each, but a thinking fox would be more fun. __________________________________ Do you Yahoo!?

Pretty slick! The ground wires and silver plated "contacts" seem to have fixed the problem I always had with the NorCal kit. And the lacquered brass pieces are very pretty. The observations: I found that I didn't need to bother with the Teflon tape around the pivot screws. Even though the shoulder washers were a loose fit (as others have reported), once the screw is secured with a nut under the base, there is very little slop in the "bearings". I used the same simple solution as on my NorCal paddle to obtain narrow spacing between the guitar picks. I simply mounted the left pick on the Inside of the arm, and the right one on the outside. As with the NorCal, the spacing closely matches that on my old trusty Bencher. I noticed a slight sticking action between each arm and the stop. This didn't seem to impair my sending, but was mildly annoying. I removed the stop and used my 220 grit sandpaper to remove the lacquer from each side of the stop. This eliminated the "lacquer to lacquer" contact and seems to have fixed the problem. Since the sides of the stop are not visible, there is no affect on the appearance. For a strain relief on the cable, I used a crimp type spade lug. I found one whose hole was just big enough for my cable to slip through and then lighly crimped it. I secured the spade under the screw that holds the stop in place. After reading on QRP-L the method of finding a lost spring, I checked my parts bowl and discovered my spring was missing. Turned out the lights, got on the floor with a flashlight and found it. That little piece sure is easy to lose! I think mine snagged on the non-skid material and then fell onto the floor... -- 73, Bob Patten, N4BP Plantation, FL E-Mail: n4bp@arrl.net Website: http://www.qsl.net/n4bp QRP ARCI #3412 SOC #1 ARS #799 Whiners #6 FISTS #7871 ------------------------------ Date: Wed, 10 Dec 2003 13:28:42 -0800 From: "PHILIP DECAIRE" To: Subject: [162754] Re: Modern keyers w/boatanchors...

If your keying voltage is positive, then you'd need an NPN or N-channel MOSFET. If its negative,, then you'd need a PNP or P-channel MOSFET. Depending on the setup, you may need a 2nd stage to go between the key and transistor to set up the proper on/off biasing. One easy way to do that is to use an internal 9 volt battery to provide either gate or base bias, and key that with your keyer. Since a MOSFET draws no gate current, a battery lasts its shelf life. Most of the boatanchors have very small key currents (grid block keying), but measure it first to be sure. Some rigs have you key hundreds of mA! Those will need a beefier transistor (and more base current) than a key circuit that only handles 1 mA or less. I had to build such a device to operate with an old Kenwood TS-520, which required keying about -100 volts at a mA or so. It worked very well. 72's, Phil WB7AEI ------------------------------ Date: Wed, 10 Dec 2003 16:37:41 -0500 From: "Ron Polityka" To: , "Low Power Amateur Radio Discussion" Subject: [162755] Re: Touch-Up paint.

Message-ID: <3FD79AC9.3040201@mindspring.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Dale - Transmitter keying circuits fall into three main categories, at least in the last 70 years or so. From approximately 1929 to about 1955 or so, most transmitters were cathode keyed, which resulted in Positive keying voltages to ground of up to several hundred volts at up to the full cathode current of the keyed stage(s). The "modern" tube transmitters began to use grid-block keying which resulted in Negative keying voltages to ground of roughly -50 to -100 volts, but at just a few milliamperes. One of the first transmitters to use grid block keying was the Johnson Ranger. The first units were cathode keyed, but a small chassis was added fairly early that converted it to grid block keying. When solid state transmitters came along, they used Positive keying voltages (usually at +12V or so) at low currents of just a few milliamps. This includes most QRP gear as well. So the "rule de thumb" is, early tube gear is cathode keyed (+ to ground), "modern" tube gear is grid block keyed (- to ground), and solid state gear is again (+ to ground). Many keyers in the 1970's "transition" era offered the ability to key either positive or negative voltages via either separate outputs or internal jumpers. By the way, before 1929 many transmitters were keyed by switching the power supply PRIMARY on and off, (USUALLY) with a relay, but not always! 73, Garey - K4OAH Atlanta ------------------------------ Date: Wed, 10 Dec 2003 17:17:27 -0500 From: w9ya To: "Low Power Amateur Radio Discussion" Subject: [162761] Re: re.

Allowing (or requiring) the fox to work some on 80 in addition to 40 might not solve the problem of the skip zone, but it ought to help. I'd like to see the limit of one contact per fox per hound maintained. Seems that even now it sometimes requires quite a while to get the pack down to the point where the fox is working simplex and hence giving those using truly QRP rigs (no rit) a chance. The same applies to the summer 20m hunts. The skip zone there is big and a lot of us were within it last summer. As I recall, one of the primary motives of the hunts was to give folks a chance to experience different propagation, and allowing direct comparison of the prop on two different bands ought to expand our understanding. The idea is to bag the fox and learn something of propagtion in the process. No need to expand to a 40m class, plus a 80m class, plus a 40/80 class, etc. Each hound bag each fox and keep track of the band on which the fox was worked.

I use a mercury wetted relay driven by a simple solid state interface. The sealed (enclosed) mercury wetted relay contacts don't stick at high speeds and can switch appreciable current and voltage. Works FB with the boatanchor rigs here. The particular relay I use is made by Clare and I see them from time to time at hamfests.
