(I\u2019ve updated them a bit for 2014) <strong>1. When setting up antennas within close proximity:<\/strong> If you are using wire antennas such as dipoles, and they run parallel to each other there will be interference on your HF operating bands in the form of hash so arrange them at <strong><span style=\"text-decoration: underline;\">right angles<\/span><\/strong> to each other and at slightly different heights.<\/p>\n<p><strong>If you use wire antennas such as dipoles<\/strong>, try to stay away from trap dipoles and use full length antennas instead. You may also wish to run your dipoles in different configurations such as have one as an \u201cinverted V\u201d and another as a sloper, etc. An antenna cut to the exact band you are using will decrease interference to and from other bands.<\/p>\n<p><strong>Do not compromise by using trap or \u201call band\u201d antennas<\/strong>. (The<strong><span style=\"text-decoration: underline;\"> only<\/span><\/strong> efficient \u201call band antennas\u201d are a log periodic and a \u201cfan dipole\u201d NOT a \u201cfolded dipole\u201d or others that claim they use \u201cbalancing resistors\u201d as this only wastes RF energy in the form of heat.) With others you may make a few contacts, but they are junk and <strong>will cause harmonic radiation. Do not fall for any ads claiming &#8220;miracle antennas&#8221;.<\/strong><\/p>\n<p><strong>Don&#8217;t waste your watts! <\/strong>Dedicated operating needs the right antenna. <strong>Wasted energy on trap antennas<\/strong> (some of your RF energy is used up in the form of heat) and that equals an inefficient radiator, especially as you go lower in frequency. On HF, try not to use vertical antennas as they receive too much man-made noise from sources such as generators, street lamps, etc.<\/p>\n<p><strong>Using a Yagi style antenna for Field Day may look impressive<\/strong>, but be careful that the &#8220;focused energy&#8221; doesn&#8217;t interfere with other operations. Know as well, that transmitting focused energy may be all well and good, but it, in receiving signals it can also make your station &#8220;deaf&#8221; from directions so you may have to waste time turning the beam&#8230;. is it worth it? &#8212;&#8211; \u00a0READ ON, THERE&#8217;S LOTS MORE INFO! &#8212;-<\/p>\n<p><!--more--><\/p>\n<p><strong>2. When NOT to use a tuner!<\/strong> Tuners are great and some people use them all the time. (This includes any rig\u2019s \u201cbuilt in tuner\u201d or any \u201cout board tuner\u201d) HOWEVER, you need to concern yourself with something called \u201cinsertion loss\u201d. Every time you use a tuner, there is a power loss due to heat of matching an antenna system to a rig.<\/p>\n<p><strong>READ THIS TWICE:<\/strong> If the antenna system is measured at an SWR (standing wave ratio) of 1:1.5 or less before using a tuner <span style=\"text-decoration: underline;\">you do not need to use a tuner to do a perfect match as the insertion loss of using the tuner will be off set by any matching it does. Power (ERP) will be lost in the form of heat within the tuner.<\/span> If you don\u2019t believe me, do a test, using a field strength meter at a distance of several wavelengths away from the antenna and you will see that what I\u2019m saying is correct.<\/p>\n<blockquote><p><strong><span style=\"text-decoration: underline;\">Tuners do not work miracles<\/span><\/strong>, so don\u2019t expect them to. Using a tuner for NVIS is another story as it is an emergency \u201ccompromise antenna\u201d.<\/p><\/blockquote>\n<p><strong>Using a tuner to compensate for an antenna that is way \u201cout of whack\u201d should tell you to use a better antenna (or FIX it),<\/strong> matched by it\u2019s length, for whatever band you wish to operate. If you use a tuner to match, say a 20 meter signal to work with a 15 meter antenna, it will also create harmonic distortion on the other bands! Don&#8217;t interfere with other operations at your site by doing this.<img decoding=\"async\" loading=\"lazy\" title=\"ICE_Bandpass_402x\" src=\"http:\/\/sanantoniohams.org\/blog\/wp-content\/uploads\/2009\/06\/ICE_Bandpass_402x.gif\" alt=\"ICE_Bandpass_402x\" width=\"200\" height=\"101\" align=\"right\" border=\"0\" hspace=\"5\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><strong>3. When operating within a tight area, as required by FD rules<\/strong>, it also pays to use \u201cband pass filters\u201d such as those <a href=\"http:\/\/www.iceradioproducts.com\/filtersrf.html#2\" target=\"_blank\" class=\"broken_link\" rel=\"nofollow\"> manufactured by ICE<\/a>. I have a full set of these HF filters and they work great. They are only about $38 per band and drastically reduce interference from your other operating posts. Make sure they are grounded as seen by the grounding lug on the top of the photo.<\/p>\n<p><strong>If your pocketbook can\u2019t afford them<\/strong>, use coax \u201cstub\u201d filters. The lengths of these and how to build them can be found at: <a href=\"http:\/\/www.k1ttt.net\/technote\/k2trstub.html\" target=\"_blank\"> http:\/\/www.k1ttt.net\/technote\/k2trstub.html <\/a> They are simple to make and easy to use. Both systems have been used by the major DXpeditions all over the world with great success. On HF frequencies make sure each operating station is properly grounded.<\/p>\n<p><strong>Do NOT use a common ground for all your operating posts. If you do, you will get \u201cground loops\u201d with energy going where you don\u2019t want it, including in to computer logging systems and the possibility of RF burns by operators or anyone touching the equipment.<\/strong><\/p>\n<p><strong>4. Make sure that each operating position has a laminated chart of frequencies <\/strong>that can be used under your station\u2019s or club\u2019s operating license. Watch out and don\u2019t operate too close to the band edges. (and remember: no one \u201cowns\u201d a frequency)<\/p>\n<p><strong>5. If using computer logging<\/strong>, always have paper logs and scratch pads ready to use in case your computers bog down or crash. (Ever use a \u201cdupe sheet\u201d? Don\u2019t know what it is? Find out and use it!) Paper logs as a backup to computer logging also makes sure you get the info (exchange) right&#8230;. in some cases (mainly contesting), having the wrong info may get your operation penalized points or even disqualified.<\/p>\n<p><strong>6<\/strong>. <strong>Whenever I operate either in contests or operating events<\/strong>, <strong>I find it advantageous to camp out (remain on) a frequency rather than tune around (hunt and pounce).<\/strong> Remember that propagation conditions will change so stick with it even if you think the band has died or other stations appear on your frequency that weren\u2019t there earlier. That\u2019s just how propagation works. Save \u201chunting and pouncing\u201d for near the end of the event when you wish to eek out those few last stations. Remember: When you move frequency, someone may take your camping out frequency and you won&#8217;t get it back!<\/p>\n<p><strong>7. Keep your calling frequency active by calling CQ often.<\/strong> Don\u2019t wait! <strong>Leave a gap of only four (4) seconds between calls<\/strong> or stations tuning by will miss your call and other stations <a href=\"http:\/\/sanantoniohams.org\/blog\/wp-content\/uploads\/2009\/06\/mfj434b.jpg\"> <img decoding=\"async\" loading=\"lazy\" title=\"http:\/\/sanantoniohams.org\/blog\/wp-content\/uploads\/2009\/06\/mfj434b.jpg\" src=\"http:\/\/sanantoniohams.org\/blog\/wp-content\/uploads\/2009\/06\/mfj434b-200x86.jpg\" alt=\"http:\/\/sanantoniohams.org\/blog\/wp-content\/uploads\/2009\/06\/mfj434b.jpg\" width=\"200\" height=\"86\" align=\"right\" border=\"0\" hspace=\"5\" \/><\/a> wishing to camp out may take over your frequency. <strong>In events such as FD, it also pays to use an automatic voice unit<\/strong> such as MFJ 434B \u201cvoice keyer\u201d. (Cost is about $170.)<\/p>\n<p>If you can\u2019t obtain one, use a cheap electronic memo reminder and just play back your pre-recorded CQ while holding it close to your microphone but not so close as to induce audio distortion. <strong>(Editor &#8211; Your smartphone might have a way to record and quickly replay an audio recording as well.)<\/strong><\/p>\n<p>This form of \u201cacoustic coupling\u201d is an inexpensive way to save your voice. I have used both methods over the years with success. Keep your calls \u201cshort and sweet\u201d using ITU phonetics ONLY. <strong> Don\u2019t use any \u201ccutesy\u201d phonetics. \u00a0BEFORE FIELD DAY&#8230;. REPLACE ALL BATTERIES IN VOICE AND CW KEYERS, ANTENNA ANALYZERS, DIGITAL CLOCKS, FLASH LIGHTS \u00a0AND ANY OTHER UNITS THAT USE BATTERIES!<\/strong><\/p>\n<p><strong>8. If you are lucky enough to cause a \u201cpile up\u201d (several stations calling you at once) answer the easiest one to hear first.<\/strong> <strong>If you can\u2019t make out complete callsigns<\/strong>, ask for the station with the easiest partial call to reply. The others will wait. Do not get flustered. <span style=\"text-decoration: underline;\"><strong>If you do, simply state \u201cQRX\u201d.<\/strong><\/span> (This means you are requesting those stations to pause, usually so your station can change operators, go flip to another blank log sheet, etc.) This will give you a few seconds to re-focus your thoughts. It is at this time where it also pays to have another person with you to help sort out any call signs or help with logging.<\/p>\n<p><strong>9. Ignore jammers.<\/strong> Do NOT bother answering them.<\/p>\n<p><strong>10. Have your station\u2019s callsign and exchange info posted in large letters<\/strong> at your operating position in case you get a bit tired or flustered so you won\u2019t forget and announce your own call by mistake. Make up some large signs to indicate what band \/ mode each station is operating on, to avoid having more than one station on the same band \/ mode at the same time (rules violation).<\/p>\n<p><strong>11. If possible, bring your own headphones<\/strong> to make your life easier and to cut down on ambient noise from your area and helps you to concentrate. An \u201codd ball\u201d pair of headphones can actually put stress on you if they don\u2019t fit properly.<\/p>\n<p><strong>12. Talk in a loud, clear voice, just like you were talking with a child and want to put a point across.<\/strong> No need to shout as it distorts your signal and makes it splatter to adjacent frequencies. Speak in to the microphone at an angle. Female operator&#8217;s voices tend to attract more contacts for some reason as well. Other stations might accuse you of &#8220;switch and bait&#8221; if you use the recording from a female operator, but answer with a male&#8217;s voice.<\/p>\n<p><strong>13. Pace yourself, drink plenty of fluids<\/strong> and let whomever is in charge know when you need a break. Do NOT be a \u201cmic hog\u201d as other people may wish to gain the experience of operating. Hopefully there will be plenty of ops around which will allow you the chance to rest a spell.<\/p>\n<p><strong>14. Learn a bit about propagation characteristics for each band<\/strong> time of day <span style=\"text-decoration: underline;\">before <\/span>you come to FD. With sunspots on the raise, the higher bands will be a bit more active than in pervious years, unless there is a solar flare or other disturbance.<\/p>\n<p><strong>As a rule: Use higher HF frequencies during the day<\/strong>, when the sun is doing it&#8217;s job with the ionosphere, and <strong>use lower frequencies after sunset<\/strong>. Find out what &#8220;grayline&#8221; propagation is and learn how it use it to your advantage. (Grayline is the &#8220;terminator line&#8221; of sunrise or sunset, but read more about how it works and how it can work for you. If you are a DXer, you NEED to know about this.)<\/p>\n<p><strong>15. If there are enough people, have someone do the logging for you.<\/strong> This way they will learn to copy callsigns under less than perfect situations and will make life easier for you. A \u201cdouble set of ears\u201d makes it easier to operate and log. It might even entice non-hams to get their license. When you aren\u2019t operating at the moment, try to keep the \u201cchit-chat\u201d down at any operating post. Save the talk when you are away from whomever is operating as it may confuse them.<\/p>\n<p><strong>16. If you want your FD to be more successful, WAIT until all members have arrived before deciding what amount of stations you wish to put on the air for the event.<\/strong> You can always change bands, even with a 1A station. Years ago one club I was a member of on Long Island decided to operate <strong>20A<\/strong>! That\u2019s 20 stations operating. The only problem was there wasn\u2019t enough people to man all the stations for the length of FD, so we were stuck at times with 10 stations we couldn\u2019t use. You can\u2019t change your exchange once the event starts. Talk about bad planning. Make sure everyone signs a log-in sheet so operator tally can be accounted for.<\/p>\n<p><strong>17. Flag all coax runs, power cords and antenna guy lines<\/strong> with brightly colored caution tape so no one walks into them or trips over them. <strong>Label each member&#8217;s equipment and cables<\/strong> so you can sort them out easier at the end of the event.<\/p>\n<p><strong>18. Never assume you\u2019ve \u201cworked them all\u201d.<\/strong> In 1991 a pair of inexperienced ops came out of the 40 meter SSB tent claiming they \u201cworked the band dry\u201d. I told them they hadn\u2019t and taking another op to log for me, in 30 minutes I worked an additional 60+ stations on that \u201cdry band\u201d by hunting and pouncing. Lesson learned: There are always other stations out there to work AND propagation changes&#8230;. sometimes from minute to minute.<\/p>\n<p><strong>19. Know the rig you are operating <\/strong>by reading each radio\u2019s instruction manual. By doing so you\u2019ll avoid problems and make more contacts. Be especially careful of the filters in complex radios as they could filter out wanted signals. Keep your operations <strong>simple <\/strong> so the next person assigned to your station won\u2019t get confused twisting and turning knobs!<\/p>\n<blockquote><p><strong><em>Have a rig\u2019s \u201ccheat sheet\u201d handy. For Field Day, basic rigs with basic filters, work the best.<\/em><\/strong><\/p><\/blockquote>\n<p><strong>20. Turn off all gear during refueling <\/strong>of any gas generators. Use proper safety procedures so voltage spikes won\u2019t harm your radios. This means to turn off your radios BEFORE the generator shuts off and wait until it reaches operational speed before turning your gear back on. You can get voltage spikes during the shutting off of the generator and the start up cycle. Use care when refueling the generator and NEVER gas it up while it is running. A gas spill even when the generator is off but HOT can also spell disaster.<\/p>\n<p><strong>21. Learn , but most of all : Have fun<\/strong>. Take lots of pictures to post on your club&#8217;s website and on any report you may have for www. SanAntonioHams.org \u00a0 \u00a0 Also, have your station license handy (the call sign you are using)\u2026 it\u2019s an FCC requirement.<\/p>\n<blockquote><p><em><strong>If you have any questions, feel free to contact me via email at: <a href=\"mailto:alonestaryank@aol.com\">alonestaryank@aol.com<\/a><\/strong><\/em><\/p><\/blockquote>\n<p><strong>This year, the BEXAR OPERATORS GROUP (W5BOG) including myself, will be running a good \u2013 old fashioned Field Day operation at the Callaham Unit at Choke Canyon Texas State Park.<\/strong><\/p>\n<p>(Editor&#8217;s Note: This is about 75 miles south of San Antonio, just west of Three Rivers, Texas.
