Here we see Dave in a file photo showing how he solders the center connector wiring as the open wire line is affixed to the horizontal wires. [image: Olive tree lies on the ground.] The antenna at W0ZSW needed work after summer storm damage. It had been replaced in a temporary configuration. The trouble began in June, when there was a stretch of three weeks rain followed by strong winds. Its roots soaked and weakened, a big, sturdy olive tree fell, taking the northeastern leg of the 200 foot antenna down with it. Several other trees went down, too - so there was a lot of clean up work to do. In late June the antenna was restrung and placed in the temporary location. Overall, the antenna's performance was marginal over the remaining summer months as band conditions were poor, combined with the temporary setup. It was replaced on Tuesday 24 March 2013 with a repaired double extended zepp (W0OXB Special) dipole fed with 450 ohm ladder line and a 4:1 current balun. Minor finishing work remains to be completed, but as of now the station is operational. Reports or comments may be directed to wa0tda@xxxxxxxx. Remaining work includes weatherproofing the current balun, performing more tests, and replacing the power supplies with a single 50 amp unit. I have located an Astron RS-50M, the model with a meter, for use in the station. The Kenwood TS-480HX radio requires two "standard" capacity power supplies to operate and even has two separate power connectors. The single 50 amp supply will have the capacity to handle the greater current demand of the radio, even in 200 watt operation. What's up for the future? - We could consider using the TS-480HX's second antenna port for another antenna. We would appreciate your feedback on the current antenna system and any other ideas you might have if you are a registered user. - Radiosport: Are there any users out there who might be interested in using the station to work toward awards or participate in contests? How would a shared resource be used in a contest, anyway? - What about the software? Is it working for you and do we need to improve it to make the station more useful? Patrick Tice, WA0TDA Courage Kenny Handiham Coordinator ------------------------------ Bulletins [image: Bob Zeida, N1BLF, at his recording desk.] Handiham volunteer Bob Zeida, N1BLF, shared an article that was written about him recently. <http://www.southcoasttoday.com/apps/pbcs.dll/article?AID=/20130824/ENTERTAIN/308240304&cid=sitesearch> As most of you know, Bob has recorded many, many hours of audio for us over the years, tackling magazine articles, books, and the periodic question pool updates. He has even volunteered at Radio Camp! If I comb the photo archives, I know I'll run across a photo of Bob up in a tree at California camp. The article Bob sends is one that focuses on his volunteer recording for us and for others over the years. He has an impressive portfolio of recordings and his work is much appreciated not only by us at Handihams but by many others around the world! Thank you, Bob! ------------------------------ Practical radio [image: pliers and wire] 43 foot verticals The 1/4 wave vertical antenna is resonant on a single band and is a good match for 50 ohm coax. What about those 43 foot verticals we've been hearing about? The whole idea of the 43 foot vertical probably came about because no one wants to deal with complexity in the mechanics of antenna design. Perhaps it would be possible to pick a magic length for a simple vertical conductor that could be made to tune on various ham bands without having to add stubs or traps. The sleek design would be good-looking compared to trapped or stub-tuned multiband verticals and would be cheaper to produce. Enter the 43 foot vertical. It is - as Joel Hallas, W1ZR, points out in QST, one-half of a 20 meter extended double zepp antenna. It is actually not resonant on 20 meters, though. If you fed it directly without a tuner, you would have to put up with SWR readings of almost 10 to 1 on 20. It would tune on 10 and 60 meters without a tuner, though. Unfortunately, these antennas just do not work well above 20 meters. In fact, in the October 2013 QST Frank Fahrlander, N7FF, points this out and suggests a method of adding dipole antennas on top of the 43 foot vertical, feeding them with coax through the hollow center of the vertical's tubing. You can check out both Joel's article about 43 foot verticals and how they work and Frank's article about these mods in QST. Joel's article is in the June 2012 issue and is entitled "The 43 Foot Vertical Monopole - What's the Magic? <http://www.nxtbook.com/nxtbooks/arrl/qst_201206/index.php#/38>" Frank's mods are in his article "Dipoles Atop a Vertical<http://www.nxtbook.com/nxtbooks/arrl/qst_201310/index.php#/32>" in the October 2013 QST. Both are available in the QST archives or in your NLS Daisy audio editions. You must have your ARRL log in credentials to read these articles on line. What do I think of the 43 foot vertical? Not much. They tune best if you are willing to add a wide-range automatic antenna tuner at the base of the antenna. Anything short of that will tend to be lossy, since SWRs can be as high as 54 to 1. You might be tempted to tune the antenna with a tuner located in the ham shack instead of outdoors at the base of the radiating element, but those high SWR numbers will mean lots of loss in the coax! You are better off with a trap antenna if you are interested in a low angle of radiation for DX and for better SWR readings with less loss. I suggest doing a web search for 43 foot vertical antennas and doing some reading. Find out what others think. The bottom line is that they can work, but the best place for the tuner is right at the base! Remember that you cannot get something for nothing. The simplicity of the 43 footer is attractive, but the extremely high SWR numbers are a concern - and a deal-killer if you try to feed the antenna with coax and tune it with an antenna tuner in the ham shack. And even if you get it to tune, the performance can be rather poor on 14 MHz and above. Remember that this column is about "practical radio", which is figuring out what works and making the most of it. Use what works for you! ------------------------------ Handiham Nets are on the air daily. If there is no net control station during any scheduled net time, just go right ahead and start a round table discussion. [image: TMV71A transceiver] *We are scheduled to be on the air daily at 11:00 USA Central Time, plus Wednesday & Thursday evenings at 19:00 USA Central Time. *A big THANK YOU to all of our net control stations! What will Doug, N6NFF, come up with for his trivia question tonight? I guess we'll just have to tune in and listen! Tune in and see how you do with the question this week, or just check in to say hello. *We maintain our nets at 11:00 hours daily relative to Minnesota time. Since the nets remain true to Minnesota time, the difference between Minnesota time and GMT is -5 hours. The net is on the air at 16:00 hours GMT. * *The official and most current net news may be found at: http://www.handiham.org/nets * ------------------------------ *A dip in the pool* [image: Pat shows off his new Plantronics USB headset!] It's time to test our knowledge by taking a dip in the pool - the Amateur Radio question pool, that is! *Let's go to the Extra Class pool and examine a question about vertical antennas:* E9C11 asks: "How is the far-field elevation pattern of a vertically polarized antenna affected by being mounted over seawater versus rocky ground?" Possible answers are: A. The low-angle radiation decreases B. The high-angle radiation increases C. Both the high- and low-angle radiation decrease D. The low-angle radiation increases The correct answer is D, The low-angle radiation increases. That is one reason that those operators lucky enough to be located at the edge of the sea and its excellent conducting salt water always seem to rack up the DX points while those who live over rocky, crystalline poorly-conducting soil have to put in extensive radial systems and still sometimes struggle to work as many DX stations.

W0ZSW was off line for almost six hours yesterday for antenna repairs. Outages: We are expecting minor outages on W0EQO as we do updates. Outages are reported on http://handiham.org/remotebase/station-status/. *Band conditions:* As of this writing, conditions on HF are good. Check http://handiham.org/remotebase/station-status/ for a current HF conditions report from G4ILO. *Operating tip: * Find out how to tell if the remote base station is already in use if you are using JAWS: - Listen to the tutorial: http://www.handiham.org/audio/remotebase/W4MQ_status_JAWS.mp3 - Read the tutorial in accessible HTML: http://handiham.org/remotebase/2013/03/05/check-station-status-with-jaws-13-or-14/ **** * [image: Pat holding up NLS digital cartridge and mailer] Don't care to download Handiham materials via computer? This digital cartridge and mailer can bring you Handiham audio digests each month, plus we have room to put the audio lecture series or equipment tutorials on them, too! * - If you have trouble logging in, please let us know. - All Daisy materials are in zip file format, so you simply download the zip file you need and unzip it so the Daisy book folder can be accessed or moved to your NLS or other Daisy player. - Tip: When in the Daisy directory, it is easy to find the latest books by sorting the files by date. Be sure the latest date is at the top. The link to sort is called "Last Modified". - You can also find what is on a web page by using CONTROL-F. This brings up a search box and you can type a key word in, such as "September". You may find more than one September, including 2012, but you will eventually come across what we have posted for September 2013. - Our thanks to Bob, N1BLF, Jim, KJ3P, and Ken, W9MJY, for reading this month. Look for these DAISY materials in the members section. <http://handiham.org/drupal2/user> *Digital mailers are important: *If you do mail a digital cartridge to us, please be sure that it is an approved free matter mailer. Otherwise it will quickly cost us several dollars to package and mail out, which is more than the cost of the mailer in the first place. We don't have a stock of cartridges or mailers and not including a mailer will result in a long delay getting your request back out to you. *DAISY audio digests are available for our blind members who do not have computers*, playable in your Library of Congress digital player. Handiham members who use these players and who would prefer to receive a copy of the monthly audio digests on the special Library of Congress digital cartridge should send a blank cartridge to us in a cartridge mailer (no envelopes, please), so that we can place the files on it and return it to you via free matter postal mail. Your call sign should be on both the cartridge and the mailer so that we can make sure we know who it's from.
