K2YWE Little Pistol 01-2011 - p6 Elements of Little Pistol Success The Right Frame of Mind Preparation Practice Attention to Detail Perseverance Learning from Others My observations are relevant to most successful endeavors
K2YWE Little Pistol 01-2011 - p7 The Right Frame of Mind QRL! Don’t forget it is a competition “it's a jungle out there”... de N6TR You will not be alone “... contesting skill includes the ability to tolerate high levels of QRM, and if you can't do that, you might as well hang it up.“... de K3ZO Think Big “If you think and act like you’re a big dog, you will convince most of the pack that you are, although you may get bitten once in a while.”... de K2YWE Don’t forget it is a competition “it's a jungle out there”... de N6TR You will not be alone “... contesting skill includes the ability to tolerate high levels of QRM, and if you can't do that, you might as well hang it up.“... de K3ZO Think Big “If you think and act like you’re a big dog, you will convince most of the pack that you are, although you may get bitten once in a while.”... de K2YWE
K2YWE Little Pistol 01-2011 - p8 Preparation Have a strategy – write it down Provides baseline guidance Try to optimize within your constraints Modify as needed in “battle” Reassess your strategy during the contest Expect to change the details Take radical departures only if you have good reason to, like one or more of your baseline assumptions was wrong “Now the general who wins a battle makes many calculations in his temple ere the battle is fought. The general who loses a battle makes but few calculations beforehand.”... Sun Tzu
K2YWE Little Pistol 01-2011 - p9 INSERT key seems to stick! Preparation Get your act in order before the performance Check your set-up well before the start Antennas, Hardware, Software, support files Set appropriate software defaults Provide enough time for fixing any problems Be well rested for the contest Listen day(s) before to get a feel for Condx Have a simple means to restart software What did I call this file...? Re-use the same name for the current contest files. Rename after the contest. Skip Next - Contest Basics Jump to “Strategy”
K2YWE Little Pistol 01-2011 - p10 Rules are published well in advance Valid contacts exchange two-way information Contest rules define the specific information Final score is composed of two pieces QSO points – Based on number of valid contacts Points per contact may vary Multipliers – Based on a unique characteristic Usually location - State, Country, Zone, Grid Total Score is QSO points times the Multipliers Total Score = “Q pts” x “Mults” Same stations may provide multiple Qs or Mults Contacts on different bands or modes may each count Contest Basics 31 W6IXB 59 59 SCV 32 W5AFX 59 59 STX 31 W6IXB 59 59 SCV 32 W5AFX 59 59 STX Individual contest rules spell everything out, including scoring Skip Contest Basics Jump to “Strategy”
K2YWE Little Pistol 01-2011 - p11 Scoring Example Pts/QSO may differ within some contests Might be different by mode, or by local or “DX” QTH Simple Multi-band contest Skip Contest Basics Jump to “Strategy”
K2YWE Little Pistol 01-2011 - p12 Sample Exchange (CQ WW HF Contest) “CQ TEST PA0LOU”PA0LOU calling CQ contest “K3AU”K3AU responds “K3AU 599 14” PA0LOU sends the callsign he is responding to, then exchange of RST and Zone “599 5”K3AU sends his exchange “TU PA0LOU”Thanks K3AU and waits for next station to call Results in one “Q” for each station, and a multiplier if the other station’s zone or country has not yet been worked on this band (CQ WW) Stations try to exchange required info as efficiently as possible Skip Contest Basics Jump to “Strategy”
K2YWE Little Pistol 01-2011 - p13 More Q’s are key to producing higher scores Q’s and Mults are both important but... Q’s fuel the engine, Mults provide the turbo boost Operating Time is fixed, so Rate must go up! Thus, Concentrate on achieving Higher Rates Rate Drivers Successful Running is a proven rate generator Being Heard and Hearing others At fixed power level, this mainly means better Antennas Efficiency - Less wasted time in and between QSO’s Look to Operating Practices and Shack Arrangement Attracting the other stations Operating Practices High Level Thoughts... Some reasoning to frame the problem
K2YWE Little Pistol 01-2011 - p14 Strategy Class Selection Band(s), modes, assistance, number of Ops, … Leverage your strengths Bands and Modes Which, when? Propagation What’s best for Q’s and Mults ON/OFF times selection Time limits Meals, sleep, “real life” periods Operation CQ vs. S&P Rates, Speeds and Timing Having a game plan pays off during the contest SOA, MUF, S&P, rates, snacks... Q’s, Mults, Bones...
K2YWE Little Pistol 01-2011 - p15 Focus on making the most Q’s Block out expected S&P and Run times, ground rules Balance with occasional short checks for Mults Base primarily on expected Propagation Range of prediction tools are available QST or CQ tables – simplest Models – most complex, better “Rules of Thumb” Temper predictions with your own observations Gray Line info can help real-time, especially on 160m and 80m Allow for time-of-day considerations What’s going on elsewhere in the world Strategy Remember that maximizing Q’s is primary to success
K2YWE Little Pistol 01-2011 - p16 Choose OFF times at lowest expected Q rates Base on your own or other stations’ history Don’t forget minimum OFF time rules Try to ensure using your full time allotment Allow possibility you may want a late slot Don’t get caught short of time at the end I usually leave a late half-hour insurance slot It’s tricky, considering the bullet above Sync with your personal needs (duhh) ON/OFF Times Make the best use of your time
K2YWE Little Pistol 01-2011 - p17 Set an average rate you want to achieve (Total Q’s) / (Operating Hrs) Set minimum rates you’ll accept Acceptable rate will vary over the contest period Include minimum rates in your Strategy Make a change if you drop below the Rate Change Freq, Band, Mode Swap Running and S&P Chase some Mults Change your shirt Rates Rules Setting Rate Rules helps you achieve QSO goals Change Something !
K2YWE Little Pistol 01-2011 - p18 Be thoroughly familiar with your software A contest is not the time for first trial Gain familiarity in day-to-day use Exploit helpful features Use practice programs and modes Modify settings to suit your style Be comfortable with Run techniques Practice with a simulator Try to operate “run style” (5NN MD DAN BK... TU) Pick a day with a good conditions on your best band Use the Best Practices mentioned later in this presentation Contest Hound Practices with CT Practice It may not make you perfect, but it will make you better!
K2YWE Little Pistol 01-2011 - p19 Station Improvements Assess Station Strengths and Weaknesses Take band by band inventory based on performance history Attack Weaknesses with biggest payoffs first Incrementally fill in the holes Expect Antennas to rank high Don’t forget to pick “low hanging fruit” Assess your Operating Practices Bounce your operation against the Best Practices (later) Adjust accordingly Improved Antennas & Running payoff most But every improvement counts – they all add up Put method behind your madness
K2YWE Little Pistol 01-2011 - p20 My Experience Operation Better exploited software features (Bandmap, SCP, …) Discovered and incrementally adopted “ Best Practices ” Biggest single payoff in Operation was Running Started Running – Had assumed not possible for an LP My running rates improved with experience and trials Station Improved antennas – eventually migrated to monobanders None exotic – Delta loop, bent dipole, and lazy U wires Eventual addition of small Yagi made a big difference Made shack changes for better” operating efficiency”... Performance improved with incremental changes
K2YWE Little Pistol 01-2011 - p21 “Better Operating Efficiency” Boom Mic & Footswitch Life is Good! Footswitch & Prop Mic Prop No Help! Ugh!
K2YWE Little Pistol 01-2011 - p22 Station Improvements at K2YWE Footswitch Frees hands for undisrupted keyboard use CW - Quick T-R transition without listening to QSK noise Boom or Headset Mic Less fatigue, freedom to move, respond to local “QRM”... Antenna Switching Quick band changes. Replaced connector swaps. Added or Improved Antennas More chance to sustain Run, snag S&P Q’s with less calls Make more “second” tier QSOs uipment “Sensible Rearrangement” of Equipment More efficient, less effort to operate... Improvements aimed at higher rates
K2YWE Little Pistol 01-2011 - p23 Antenna Improvements What assets exist to hang antennas on? Use all the property lines to full advantage Try to design a system using monobanders Add/change antenna to help your weakest band Consider fixed antenna with gain to EU or West Enable a new band, like 160m for New Mults and more Q’s during slow times Put up even a minimal Yagi if possible Be innovative within your constraints

K2YWE Little Pistol 01-2011 - p26 Software (S/W) Use your Radio and Keying interfaces Build or buy and integrate them if you haven’t already (Appendix A) It’s very hard to make and sustain high rates without them Recommended S/W Setup (CT keywords SHOWN) WORKDUPES- BANDMAP & ANNOUNCE Windows CORRECT call signs - RATE Window Super Check Partial- SCP Window Stop on auto CQ- SCORE Window Spotting Network? View as a strategic decision Can be a valuable asset, especially in S&P Remember caveats about wasting time chasing Mults Does not alleviate you from confirming all entries Use a contest-oriented program and set it up to facilitate high rates
K2YWE Little Pistol 01-2011 - p27 Software Features Most Useful to Me Skip All but Bandmap Skip all All Detail- Jump to Best Practics
K2YWE Little Pistol 01-2011 - p28 Dupe Alert (CT screen) Check for duplicate entries is automatic upon callsign entry TI3TLS Alert as DUPE with time & date of previous QSO TI3TLS Skip All but Bandmap
K2YWE Little Pistol 01-2011 - p29 Matches callsign fragments against database created from recent contest logs and current logged contacts... anywhere in the callsign Check Partial Call (CT screen) Call fragments yield possible known contester callsigns Skip All but Bandmap
K2YWE Little Pistol 01-2011 - p30 the Bandmap (CT and N1MM screens shown) Tells you who is on what frequency, if worked before, and if needed as QSO or multiplier Data is entered by hand or automatically from spots Map updates periodically to expunge stale data Own frequency can be ‘centered’ or scrolled The bandmap saves time in Search & Pounce mode Skip Bandmap Jump to SO2R

K2YWE Little Pistol 01-2011 - p35 Tips and Best Practices “Best Practices” are what successful competitors say works for them.
K2YWE Little Pistol 01-2011 - p36 Some CW Tips* - CW Do not be intimidated by stations too fast for you to copy. Start with the slower stations higher in the band. Don't worry if you have to hear a call several times to get it. As the contest goes on your will improve! Call CQ high in the band at a speed comfortable for you. Don’t be shy about sending QRS. Most stations will slow down to your speed. Try moving frequency a bit if you can’t seem to be heard. Often receiver bandwidths in a crowded band are set very narrow. Don’t let your code speed keep you from enjoying CW contests *Some tips are courtesy of the 1999 YCC “Cookbook”
K2YWE Little Pistol 01-2011 - p37 Some Phone Tips Use conventional or unmistakable phonetics “Duck Soup” are poor phonetics for “D S” Use Standard or “Common Use” phonetics (countries, cities...) Maintain a “friendly sense of urgency” in your QSOs Chattiness will slow your rate and lose you contacts. Do not be intimidated by stations talking fast or unintelligibly. Firmly ask until you get all the exchange info. Use “again?” It is usually better to ask for one piece of missing info at a time. Listen to what is on your frequency when working split. If you can hear it, you can better time your call or defer until later. Apply these basic Phone tips for starters
K2YWE Little Pistol 01-2011 - p38 Every point counts! There’s no such thing as “not worthwhile” When things are slow, call for “anybody” A rule of thumb strategy Work bands that may close first. Move with propagation. This often means 10-15-20 in a.m. then 40-80-160 later on. Try running rather than chasing spots when high bands are open. Go after the Mults when 20 has slowed, but 40 hasn't opened yet. Keep multipliers in mind “Move” Multipliers if you can do so efficiently Have frequencies on each band set up for quick jaunt Balance the effect on rate and total score when chasing Mults Best Practices Basics* - Overall Overall * Some of these tips are courtesy of the 1999 YCC “Cookbook”
K2YWE Little Pistol 01-2011 - p39 The Master Callsign Data Base is not the Bible Verify the callsign of the station you're working BV6U and 5C8N are not real callsigns (6V6U and HC8N). Don't log them that way. Always HEAR the call that the station is signing and log it correctly. Best Practices Basics* - Overall Overall - continued * Some of these tips are courtesy of the 1999 YCC “Cookbook” You mean that’s a busted call?
K2YWE Little Pistol 01-2011 - p40 “fresh meat” “fresh meat” S&P rates can be very high early in the contest fo Everyone is for you. quickly hop from You can quickly hop from station to station with little fear of Dupes. safe to call You are usually safe to call first and fill-in the call at the QSO end. Use early S&P to find a spot to CQ You can maintain a high rate while searching for a clear spot. It beats the alternative of establishing a frequency before the Test Be sure to try CQing late in the contest You will be “fresh meat” to many that have been CQing all along. They will be seeking to squeeze out the last few QSOs. Repeat only what is missing when asked for a fill Repeating known parts wastes time and possible “clear times.” QRL?... Best Practices Basics - Overall Overall - continued
K2YWE Little Pistol 01-2011 - p41 Do you really want to ask QRL? “Can anyone honestly believe that there is a single KHz anywhere in the relevant portion of the 20 meter band that is NOT in use somewhere in the world during the CQWW?”... de K3ZO One Approach... Pick a “clear” spot and CQ without “QRL?” You will only invite others to take the frequency by asking. You’ll find out quickly enough if the Freq is in use by calling CQ. This is very controversial. Many hams feel that not asking is rude. You Decide. Use “QRL?” if you have any doubts or are thin-skinned!
K2YWE Little Pistol 01-2011 - p42 Best Practices General Use K3ZO's "Rule of TWICE" – modify “twice” as sensible If you can't get a station after calling TWICE, move on If he doesn't ID after transmitting TWICE, move on Don’t waste time repeatedly calling DX that has moderate Sigs when the band is otherwise quiet from their part of the world They are probably “opening the band” with lots of ERP Enable and use the band map in your logging software Insist on fills until you get all the info. Use “Again?” on phone Don’t log the QSO without complete info. “Sorry, No QSO” Keep the width of an SSB signal in mind Be sure you are away enough from strong stations running not to be covered by a pileup you can’t hear
K2YWE Little Pistol 01-2011 - p43 Running Use the widest IF bandwidth you can stand Less chance to miss off-freq callers, especially on CW Don’t break a run to pull one station through Your rate will suffer if you take too long You will drive away impatient waiting stations Use only a quick ‘Thanks’ if stations are waiting They know your call. Don’t waste time on it. Throw in your call every few Q’s for the uninitiated Send complete exchange with a partial call Nearly all Ops will correct you, good ones without a missing a beat Fix the call during his transmission more Best Practices...
K2YWE Little Pistol 01-2011 - p44 more Best Practices... Running - continued Call CQ when bands are dead for the day or worked out Call CQ when the band is active if you are able to find a frequency and hold it Always work Dupes ("WORKDUPE" in CT) You might not be in his log If you can't drag a station's call through after trying TWICE, ignore him and start calling CQ again. This is part of K3ZO's "Rule of TWICE." Modify "TWICE" to suit your station capabilities and contest circumstances. Enable call sign correction in your software. This will send the corrected call as part of your goodbye message ("CORRECT" in CT)
K2YWE Little Pistol 01-2011 - p45 more Best Practices... Running - continued Speed up if your run is being sustained This is especially true in contests like SS where the exchange includes your call sign. Slow back down appropriately Hit the SEND key as soon as the call is in your head. Finish typing in the log during the automated response or while talking Some programs can do this automatically after n characters Move Multipliers to other bands if you have the time Pick frequencies in advance
K2YWE Little Pistol 01-2011 - p46 more Best Practices... Running - continued If another station calls CQ on your frequency, try "QRL" or "Frequency in use, QSY" Don't engage in extended frequency fights If QRL/QSY fails, it almost always pays to move Sometimes you can move up or down a bit in order to lessen the QRM and still hang on to "your" frequency NEVER NEVER NEVER acknowledge a "jammer". NEVER. Just keep your pace, and don't change your tone of voice on phone or even synchronize your calls to his QRM. Often throwing in a few fake Q’s will discourage the jammer The Complete Best Practices Collection Appears in Appendix B The Complete Best Practices Collection Appears in Appendix B
K2YWE Little Pistol 01-2011 - p47 A Word About Single Op 2 Radio Everyone has their own idea of an efficient SO2R layout... K1PT S02R Setup two radios, two computers “Special” contest switch at DF0WA S02R one computer An earlier two radio setup (no PC)
K2YWE Little Pistol 01-2011 - p48 It’s easy for SO2R to be a distraction KISS (Keep It Simple Stupid) is key Start with a simple setup Use SO2R only when things are slow CQ #1, S&P #2 or Alternate CQs Modify your setup operation with experience Many top Ops swear by it (i.e. N6TR) Has potential to add significantly to your score Some don’t use it at all (i.e. K3ZO) p.s. I’m at stage one – few or no SO2R Q’s per contest - dbz SO2R Save SO2R until you have nearly exhausted other improvements
K2YWE Little Pistol 01-2011 - p49 If the IF is being "pumped" by stations nearby (and in the AGC bandpass) trying running with your AGC OFF”... de K3RA Noise limiters can cause noise or clicks when “pinged” by strong adjacent signals. Turn off unless you have no choice. * Miscellaneous Receiver Tricks Hints and Kinks that you may not have considered *On the Yaesu 1000MP, turn the adjustment knob full CCW, even when both NLs are off.
