NI FN: That's kind of a loaded question , is n' t it. The hobby certai n ly is changi ng , and in ways that 1 d on 't particularly care for. Ham radi o for me is bu ilding a radio, an ante nna. and talking to some guy o n the othe r si de o f world (us ing C WoI' course) who has the same interests . B ut, for a maj ority now (in tcnns o f simp le numbe rs, anyhow ), it's going to the local radio superstore or Internet site and buyi ng an HT so they can use the repeater to talk to somebod y on the other side of to wn who has the same interes ts. W hat a change, ove r twenty years or so ago. Un fort una tely. while admin istration o f th e hobby has never been " maj ority rules," we are ge tting to the point where a majori ty of the ad ministrators have come into the hohhy through the eas ier and less technical routes, and those are the guys who make or influence policy and regulations.

Co nse q uently, we decided to do our "own th ing" once again and sent o ff a series of E-mails to those travel agents listed in the guidebook. One particular agent, Cortez Exped itio ns, responded with such e ffi ciency and enthus iasm that we almost im med iate ly started negotiations for our o wn tailor-made itinerary. We opted for o ur tested formula o f a week's fairly intensive trave ling and
a week relaxing o n a beach. when l could play a hi t of radio . We also found that if we booked our international flights on Air Madagascar - affc ctiunatcly known as "Air Mad" then all o ur intemal lli ghts would be heavi ly d isco unted. Fl ights were from Paris-Charles de Gaulle airport. so we cashed in so me air mil es and booked feeder lli ghts fro m Bristo l to Pari s to make the connections . When the revisions to the IOTA Di rec tory were im plemented in 2()(x), a new island group - " Madagascar's Coas tal Island s East: AF-090" - was created and I noted that this included Nosy Bohara (alk/a He Sainte Marie ).

Those "Badger" identification badges were programmed with "hidden clues." Some had a numberlletter combi nation, o thers just a number. The object was to copy the clue from another's badge in Morse, add the data to yo ur " fill in" sheet and complete the qu ote se lected for the contes t. You have n't heard QRM until yo u' ve heard 150 Morse-generating badges all going off at once ! To compete required that you circ ulate amongst the throng, gathering information from each attendee and giving your data in return ! Now add the bright flashing LED to the clamor and perhaps yo u can im agine what it was like! BEDLAM!!! With prizes for the winners.

Letter From the Other Side Re: Celebrating the bisesquicentennial of a shocking event.
This i tem from The Hertzian Herald is published 10 commemorate the 250th anni versary of the first prectical app lica tion of elect ricity (Franklin 's ligh tning rod, june-October 1752, d epending a ll how yo u see i t) .
t age 2 1, I was j ust trying to establish myself as a respec table young man. so I felt like a perfect foo l. run ning aro und out there in that field. J kne w that if an yone saw me I would have a great dea l of e xpla ining to do, And , indeed. for years afterward the pu lpits aro und Philadclphi a rang with the warning that only Sata n himself could have co ncocted such a scheme as to poke pointed metal stic ks up into God 's heaven. literally daring Him to send lightnin g bolts down to destroy us. The gus ting wind spun the kite in di zzy c ircles each time I tossed it into the air, and I considered it fortunate that the sharp wire poi nt Father had attached to the top of it buried itse lf in the ground each time it landed, rather than into my head or shoulders. Finally. as the ra in started to fall and the wi nd steadie d, I got e nough tail on it to keep it sta ble. a nd it ro se into the lowering clouds. Father was seated in a shed at the

He wouldn't touch the wet string. but only held a dry silk handkerchief he had tied to the end of it. After some time sparks began to j ump from the end of a large iron key he had a lso tied to the end of the moist string , He then touched an electroscope to the key, and the lea ves inside the glass via l float ed apart. "T hat clinches it. Willi am," he said. " Lightning and e lectrici ty are one!" Father had been experimenting with electricity si nce 1746, ge nerating great sparks by rubbing a rapidly rotating glass sphere. and igniting spirituous fumes. and tingling folks with "electric shoc ks." which I found quite di sagreeable. On several occasions he deliberately killed turkeys with these shocks, and at least once he very nearly killed a goose - himself - knocking himsel f qu ite senseless. He claimed to have ignited a name by an e lectric di scharge sent across a river, using the river water as the co nductive medium - a feat which I never witnessed. but if true, it anticipated Morse 's teleg raph
by nearly 90 years. and Marconi's wirele ss by some 140. In 1750. electri city was tho ught to consist of two fluid s: vitreous (obtained by rubbing glass) and resinous (from rubbi ng rosin ). Father first proposed that it was a single fluid. flowing between two poles that he named positi ve and nega tive. He was also the fi rst to connect electric sources in series. which he called a battery. After the success of the kite experiment. Father knew e xactly what to do. He recognized that the c louds and the Earth we re the two plates of an c normous Leyde n jar (a ca pacitor. I believe you ca ll it in 2002). and he proposed to discharge it in the usual way, only on a much larger sca le. In October his newspaper. the Pennsylvania Gazette. carried comple te direc tions for performi ng the e xperime nt - carefully phrased in the passi ve voice (a kite is to be made) to avoid revealing that he himself had done it. That sa me issue earned an advert isement for the ne w edition of his Poor Richard s Almanac, whic h in tum contained similarly worded instr uctions for constructing a gro unded lightning rod. with confi dent Conrin ued on page 54 73 Amateur Radio Today • October 2002 35

Saving the Fleet Of batteries, that is.
It is interesting to observe that batteries cared [or by a single user generally last longer than those operating in an open fleet system where everyone has access to them, bur no one is accoull!able [or th em. n this article. we look at two distinct battery users - the personal user and the fl eet o perato r - and provide suggestions for prolonging battery life and incre asing reli ability in the rather harsh environme nt of fleet use . A persona l user is one who operates a mobile pho ne. a laptop. or a video
camera for business or pleasure. He or she will likel y follow the recom mended gu ide lines in caring for the buttery, The user will get to kn ow the irregularities of the battery. When the runtime gets low. the battery will get serviced or re placed. Critical failures are rare, because the owner adj usts to the performance o f the battery and lowers expectations as the battery ages. The Fleet user. on the other hand. has little personal in terest in the battery and is un likely to tolerate a pack that is less than perfect. He simply grabs a battery from the charge r a nd expects it to last through the shift. The hattery is returned to the charger at the e nd of the day, rea dy for the nex t person . Perh aps d ue to neg lect. fl eet batt eries ge nerally provide a shorter service life than those in pe rsonal usc. How can fleet batteries be made to last longer?

missions The high failure rate o f fl eet baueries. excessive replace me nt costs. and poor reli ability have prompted m any organizatio ns to se rvice rechargeable baueri es with a battery ana lyzer on a reg ular basis. Today. battery ana lyzers play a critical role in prolonging baucry life and m aintaining a healthy battery fleet. Conven tio nal wisdom says that a new battery a lways perfo rms fla wlessly. ye t many users re alize that a fresh battery ma y not a lways meet the manufacture r's spec ifications. With a batte ry analyzer. weak batte ri es can be identi fied and primed. If the capacity does not improve. the packs can be re turned to the ve ndor for warrant y replacement. Entire hatches o f new batteries ha ve been se nt bad because of unacceptable performance . Had these bauerie s been released without prior inspecti on , the whole system would ha ve bee n jeopardized. resu lting in unpredi ctable pcrfonnance and frequent d owntime . In add ition to getti ng new batterie s field -ready, battery ana lyzers perform the important fu nction o f restoring weak batteries and weeding out the "d ead wood." Weak batteries can o ften hide among the ir peers. But whe n th e syste m is pu t to the test in an eme rgency. the se no npcrfonners stick o ut like a sore th umb. It sho uld be noted th at battery analyzers are most e ffective in restoring nickel-based batteries. Lithium-based batterie s lose capac ity mostly du e to ag ing . and such performa nce loss is nonreversible . Organizati ons tend to postpone hattery maintenance until a crisis situ ation deve lops. O ne fire brigade using two -way radios e xperienced chronic com m unication problems. es pecia lly during callouts lastin g more tha n tw o hours. Although their radios functioned in the rece ive mode. they were not able to transmi t. a nd firefi ghters were left u naware that their ca lls did not ge t through. The fi re brigade acquire d a Cadcx battery ana ly zer and all batteri es were serviced th rough exerc ise and reconditio ning methods. Those batteries that
d id not reco ver to a pre se t ta rg et capaci ty were replaced. Shortly thereafter. the firefighters were sum mo ned to a te n-ho ur call th at demanded heavy radio tra ffic . To their a ston ishment, none of the two-way rad ios failed. The success o f th is fla wless operation was c red ited to the exce llent performance of their ha tteries. The fo llo wi ng day. the captain of the fire brigade personally co ntacted the manufacturer of the batte ry analyzer and enth usiastica lly endo rsed the use o f the device . Batteries placed o n prolonged sta ndby commonly fa il whe n needed in a n emergency. A Cadcx representative was a llo wed to view the State Emergency Management Facility o f a large U.S. city. In th e fortifi ed underground b unker, over one th ousand batteries were kept in chargers . The green lights g lowed. indicating that the batteri e s were ready a t a moment's noti ce . The officer in c harge stood e rect and confidently said. "We are prepared for any eme rgency. The rep resentative then asked the offl eer to ha nd over a battery from th e charge r to check the state o f health. Within seco nds. the battery analyzer detected a fai l cond ition. In an e ffo rt to make good . the officer grubbed another batt ery from the charger ban k. but it failed. too. Subseq ue nt batteries te sted a lso failed . Scenario s such as these are common . Poli tical hurd les and lack of fund ing o fte n make it difficult to so lve such prohlems q uick ly. A maintenance program in wh ich each batte ry is cycled on a monthly basis with a hattery analyzer would pre vent suc h a problem . In the me antime. the o nly thi ng the officer of the emergency fac ility can do is pray th at no emerge ncy wi ll occur. A nother user group th at re lies hea vi ly on ba tteries is the m ilitary. Defen se organizatio ns take great pride in e mploying th e hig hest-q uality and best-performing eq uip me nt. Whcn it c omes to rec hargeable batteries. ho wever, there are exceptions. The battery o ften escapes the sc rutiny of a fu ll military inspec tion and o nly its visual appearance is chec ked . ~ a in te nance

require ments arc frequent ly ignored. Litt le effo rt is made in keeping track o f th e battery's state o f health. cycle count, and age. Eve ntually. weak. batteries get mixed with new ones and the system becom es unreliab le . As a rcsuit. so ld ie rs are carrying rocks instead of batteries. A battery m aintenance program wi th battery anal yzers keeps deadwood out of the arsenal.
Sum mary Un like ind ividual battery users who kn ow the ir batteries like a good friend, fleet users m ust share th e batteries from a po ol of unknown supply. While an individual user can detect eve n a slig ht reduction in ru nti me. flee t operators ha ve no way of knowing the behavior or condi tion of the battery whe n p ulling it from the charger. They arc at the mercy of th e battery. It 's a lm o st lik e playi ng Russian roulette . Increasing ly. flee t batte ry users arc setti ng up ba tte ry maintenance p rog ram s.

Sleeper Package Comes Awake If you are like me, every now and then something com es alon g that looks good but y ou just ca n '( seem to make it click. This happened to m e with
.1
program named PSK-PAL, which i s, as
you can tell by examining th e name, obviously another I'SK com m unications program.
T
here h. a lillie history to this software. It showed up well over a year ago, and I have lo st reco rd o f how I became aware o f its ex istence. I do wn loaded it and it is unique in certain re spects. One thai stands o ut is the fact there arc three recei ve panes and each ha s its own waterfal l. Kinda fun . The software always has been good on the receivi ng end, hUI I had problems getting it to dri ve the audio for transm it. l tricd it in several computers, und er differe nt operati ng systems and corresponded with the author, Erik VK7AAR . I thin k I on ly identified one user o ver the air and I was not in contact with that ham to see how it worked for him , and Erik was at a lo ss. Obviously, it must have worked fo r him and others in his neck of the wood s. I put the PSK ·PAL o n a back -burner and never qu ite forgot abo ut it. In the ensu ing mo nths. I found a tru ly great SSTV edi tor by Erik, SSTV-PAL that works flawlessly and has been the subject of a couple of columns here. The luck of the d raw seemed to prevail recently as I was getting the Web site lin ks co rrected and I ran across a very recent modification for PS K·PAL on Erik 's FTP site. I sho uld spe nd a few lines here and explain something about the URL listed for PSK·PAL and SSTV-PAL. Thi s site is a strictly no-frill s d irectory o f the files avai lable fo r do wnload by yo u a s an interested ham . I am sure when you bring up a page that say s si m p ly. " Directory of I- erac" yo u are sure yo u have hit the wrong key somew here. Not so, you are really there. The a vailable file s are the product of the "ge nius at work" and are ready to he downloaded and enjoyed.
The rest of the story Th ;11 is j ust what I did . T he orig ina l zipped fu ll ve rsion of PS K· PAL is a bout a 1.6 42 73 Amateur Radio Today • Octobe r 2002
megabyte file. T he latest modificat ion d ated J uly 4. 2002, is a Huh: less than a 0.25 Mh download . Very quic k. and I insta lled the two tile s tha t appeared after the unzip in the PSK-PAL direc to ry. They were re placements for two existing files. All that was len was to boot the program and check the se tup. The program uses the PTT which setting agreed with the co mm port int o whic h the PIT c ircuit is p lugged. I thoug ht I was up and running. Cl icking transmit seemed to wo rk . The rig keyed up , but I needed to tweak the Windows sound driver. I am still behind the times. That is, I am using the cables direct from the soundc ard to the accessory jack on the back u f the Icom rig. Those o f you usin g the commercial interfaces need only adjust a knoh to set the ALC level. Along with this is a nice lill ie "Set Tran sm it Out pu t" fu nction found in the Soundcard pull-do wn me nu. C licking here di splays a slider over the TX bu tton o n the right of the mon itor display. You can watch your ALC and power meter while you ad just here and then cli ck "Do ne ," and the selling remains for subseq uent hoot-ups. I still had to revert to the Windo ws sound driver wh ich does not always stay where I put it, but that is just a local probl em . If I ever ge t serious about thi s stuff I will ... cure that? Anyway, bingo! T he transmit problem was c ured. I hunted around and found a contact and the repo rt was very good. Then I went back and started reading the He lp tile . T his program has some excellent feature s that may just e ntice you to give it a try. To begin. I found J had not ed ited the macros to fit my needs. Easy chore, right click the macro button s and edit. Everything you need to know is a vailable in the edit screen. The n I di sco ve red a built-i n log feature . As the Hel p fllc indicates. PSK·PAL
is intended fo r c asual ragc bcwing and this means the log con fo rms to the no-nonsense. non -con test principles. Howe ver, yo u will find it is quite intuitive. I have 110 reason to believe the log can be exported into any o ther log . but that is not something I would ho ld against the software. Most casual hams don' t req uire such refinements. Speaking o f cas ual ragchewlng. that is my ma instay. It is not u nusual fo r me 10 make a contac t that lasts in exce ss of a half ho ur. T he re is all e xceptio n. This is being written in midsumm er a nd the paths are not ho lding up for long transmission s, but if the path does hold up then there c an he a 101 of short bursts of really Impo rta nt info. Nice thing abo ut the d igital modes: T hey do hang in far better und er marginal condit ions than phone . O ne of the no ve l things I fou nd wa s the case in swapping between the three receive panes. What always mak es me take a deep breath when using a program with more than the " main" receive display is what to do when I spo t a CQ on one of the other panes. Not a problem here . I found two bu ttons labeled " Use Ch I'' and "Use C h2". What you do is simply click on e o f these buttons and the swap o f tex t as we ll as the waterfall trace selected la kes place . You are ready to give that fello w a call ju st that easily. T hat is fun and refreshing. I also found that, even with my late mode l soundcard, tha t see ms 10 get me in trouble "chasing" signa ls o fte n as no t. every QSO turnover was almost exac tly o n frequenc y, and no comp laints from the o ther e nd . I did notice a feat ure that had tnt" wondering for a minute, speaki ng of tun ing. I found that two signals with a space of perhaps 70 Hz betwee n offered a tuni ng problem . The program wou ld "home-in" on the stronger signal. A tri p to the AFC pull-do wn revealed a simp le solutio n for th is phenomenon . The
AFC width is se lecta ble. I like to have a program fo llow a wand ering sig na l most o f the tim e. But you ca n have th is by choice , You are affo rded 10 Hz, 50 Hz , and 100 Hz. • c ha nged it from 100 H z to 50 H z. and seemed to gain the best of both world s. It wo uld still follo w straying signals as well ax allow tuni ng to the weaker signal I w ished to track . PSK-PAL is a 101 o f fun to usc . not on ly because it is di ffe rent, h ut yo u can get the fee l of w hat the ham was thinking when he sat down to w rite something that fit his opera ting sty le . He has answered so me o f the need s by usi ng approac hes not fo und e lsewhere. When yo u ge t a chance , g ive it a try.
The Chart o n t he Web Many o f yo u ha ve responded fa vorabl y to the ease o f use o f The C hart since it is o n the Web. C hange come s slowly. A fte r two mo nths. r real ized a notatio n belong s in the head ing to thi s colum n . B ut, e ve n so. yo u were find ing th e Web site j ust fine . T he co nve nience facto r is the part thai is mo st worth the effort to get it in p lace . T he ty pi ng erro rs are e lim inated . Just sim ply decipher the sho rt defi nitions I have gi ven and cl ic k. yo u are o n yo ur way. G lad I d id it, o r shou ld I say. "l am do ing it?" It is o ne of those projects that goes on for a long time . To be ho nest. I thin k I had the links organi zed and work ing just in the nick of time. le ss than a week before the A ugust iss ue showed up on yo ur doorstep. Anywa y. allthat aside. I ran across som e ve ry good ideas w hi le gett ing the o nline Chart in order. Some o f it came whi le resting the links (Gee. that is q uicker at this end a lso). A nd so me came as I was compari ng the ether vers ion o f T he C hart o n the WA2HNG site. Bob had very g raciously included T he Chart in his Web site for th e better pan o f a year while I procrastinated in setti ng this one up . Bob has some lin ks he added that are j ust plai n fa sci natin g . A nd . o f course. I have been letting some o f th e new deve lopments pass me by. So. I will start playi ng catch- up. A s I was looking th rou gh the li nks. checking 10 m ake certain they wo rked . I ran across several interesti ng ideas in need o f d iscussion. Not the least o f these was the PSK· PAL m odifi cation thai is d iscussed at the beg inning of the co lum n this mo nth . T here is so m uch inform ation available for the ham o n the In ternet th ai it almost defies organization. The reason I say th at is. firs t each person is an individual with his O WII ta stes. Secondly, though we are sim ply look ing at a sma ll segment of w ha t is available , a lot of information overlaps.
F ig. J. PSK-PAL - Th is is a screenshat where I actually have it Wiled ro and decoding 3 different PSK signals. Note the separate waterfalls. The macro.f a n' easily edited af ter a right-click. And there are 3 lIIacro sets selecta ble with the boxes j ust below tiie b1l1101lS. There tire h ot-keys for Xmit a nd Rcve and the function keys also activate the macros which call include Xmit and Nn e or Ja il may simply click the TX and RX boxes. The Hell' file is to -the-point and tho rough. The p rogram has tool-tips yOIl calltllm all so J a il call get a quick run-down 011 any unfamilia r button o r feature when J ail touch it with your III O/l se cursor: YOII COIl stop Ilu' a uto-scroll of the main recei ve pane hy clicking the " E" ha/p m )' Ill' the rigllt side. a llowing J ail ro ra ke a no-hassle look back ar p revious information. The re a re individua l BID readings f o r all J received signals. The "casual " log line at the bottom a llows YOll to tvp e in whatever YO/l desire and it all reappears when yon type in the callsign next rime , Not a contest p rogram. but a nice intuitive piece of software f o r relaxed operators: and did J mention FREE ?
I find . e ve n with the multit ude o f ex cellent se arc h e ng ines ho ve ri ng o ut there. it is d iffi cult 10 fi nd prec isely what we are look ing fo r eve ry time. So I seulcd back 10 loo k a t j us t T he C ha rt and rea li zed I

Coaxial Test Devices Last m onth we covered the epplicetion of coaxial relays and discussed som e attributes and fa ults of parricular connectors. As tar as most test equipment is concerned. coaxial connector use varies greatly. However. clues about the use of BNC and UHf conneclOrs .1 l m icrowave are very limited, esp ecialty above 1 GHz.
M

power meier is a work horse on my test bench. It is limi ted in power ran ge from minus 20 dBm (0 plus 10 d Bm (maximum). Freq uency-wise it is rated from 0.1 to 12A GHz, with its thermistor powe r head a ~7 XA which is lilted with a coaxia l "N" co nnector. As a g reat co m mercial piece of tes t eq uipment. it demonstrates con fi dence in microwave operation for the " N" connector. There are better connec tors , such as the APC-7 con nec to r. which is a ge ndertess. co ns tant impedance c o nnecto r. W hat is meant by constan t im pedance is that SW K thro ugh the co nnecto r measure s like the co nnector was not the re, mimicking a section of c oa x c able , The " N" c o nnector consisting of a pin and soc ket create a smal l but man ageable impe dance irreg ulari ty.

Wh ile the A PC-7 con nec tor is q uite ex pensive. it offers nea r perfection in co nnec tors co nstruction. maintaini ng the center pin's exact d iame ter. It is used primarily in high end test instrumenta tio n. The APe-7 is kind of like a connec tor to test how good an " N" connec to r is performing .

In general. they' re quite prevalen t in test device .... Did you e ver no tice that for V HF usc the B:"lC and U HF connectors abound. hut for ~50 M Hz ope ration o n some eq uipment the " N" connecto r is used?

(A suitable power au enua tor co uld be used 10 make the measurcmem.) Howe ver, if you do not have, say. a 20 dB aucnuator rated at 50 watts. wha t do you do?

Direc tional couplers can e xhibit very high power capabili ties and come in various dB levels (no rmally 10, 20, and 30 dB reduction bet ween source and co upler o utput).

A sa fe method to measure a transmiucr's power level is to place an addi tional attcn uator o f at least 10 or 20 dB on the coupler o utput to not o verpower the 478 power meter head . In th is case, 10 watts inp ut to the 30 dB coupler, p lus, say, 10 dB o f added ancnuator fo r safe ty 's sake , would produce zero as read on the microwave po\\'er meter. Remember 10 watts = +40 dB , minus 30 dB for the co upler and 10 dB for the anenuator = ze ro dBm.

Work it out as +40 is 10 waus, subtract 10 dB and that's I watt. Double I watt (+3 dB ) and that 's 2 watts. Going hackwards, +40 = 10 watts. minus 3 dB = +37 = 5 wa lls. minus 3 dB = +34 o r 2.5 watts, and soon.

HOMIN6 IN continued from page 51 to schedule a tcn-meter Tt-h unt. I j ust had to try RDF! Stories such as these and the "Carl and Jerry" se ries in Popular Electronics magazine got me going in ham radio. They fueled my imagination fo r new gadgets and encouraged me to learn more about radio and electronics, w hich led to a career as an engmeer, Tompkins, a pro lific wri ter o f westerns and screenpla ys, produced three ham radio novels in the 1960's, ai med at teenage and pre-teen boys. After a twenty-year hiat us, he came back to ham radi o as a subject and wrote three more Tommy Rockford novels in the four years before his death in Novembe r 1988 . He is missed. bu t o thers ha ve ta ken up his effort 10 promote ham radio throu gh advent ure stories. Today 's best-k nown ham radio novelist is Cynthia Wall KA71TI. She writes from a much different perspective tha n Tompk ins. Unlike th e a thl etic , technicall y inc lin ed Tommy Rockford. w ho seem ing ly spe nt 24 ho urs a day be ing a ham, C indy 's lcad character is Kim Stafford KA7SJP. a teenage girl for whom ham radio is j ust one part of a we ll-rounded life. You would expect that such a heroine would appeal primari ly to girls Kim's age and younger. Ind eed, that was C indy 's intended audi ence , but her stories have much wider appeal. Several adult male ham s have told me that o nce started, they had to stay up into the wee ho urs to fini sh reading Wall's books. Wi th ca reful research and atte ntio n to de tai ls, Cindy has produced fou r ham radio thrillers for ARRL. Nighr Signals, her first book, is the on ly one that inc ludes RD E Published in 1990, it tells how Kim and ham radio come to the aid of her new friend Marc Lawrence KA71TR when he is inj ured o n a solo hik ing trip high in the Cascades. But my favorite is her second boo k., /lostage In The Woods. If yo u read Chapter 3 and the A utho r' s Note, you' ll see wh y.
The Foxhunt Adventure A noth er wr iter fo llo wing Walker Tompkins' legacy is Dave Casler KF.00G, author of The Foxhunt Adventure, published
by MFJ Publishing. wriuen for you ng read ers, it is a story o f four youth anending high sc hool and working in a pizza parlor in Louisville, Colorado, a town near Boulder. Illegal drugs are appearing o n the campus and Ben Thompson KE00G hears something very unusual in his hamshack that might help idcntify the source . The next few days arc fill ed with da nger and intrigue. Ben and his pizzeria coworkers learn important lesso ns about ham radio technology and human interaction. O ne begins wo rkin g toward her ham rad io license. Her in terest in improving her German by talking to DL hams and her attraction to Ben give her a dual incentive to study. Later, he r buddi ng knowledge o f C W becomes vitally im portant as the story unfo lds. Dave C asler learned about radio in his c h ild ho o d wh en h is aunt g a ve h im a Hallicrafters shortwave rec..c ivcr. This interest led him to serve as an electronic systems officer in the US Air Force, and to get an advanced degree in electrical engi nee ring. Today he is an engi neer in aerospace. " Like you, I got into ham radio because o f the Walker Tompkins books," he told me. " I always wanted to do some thing similar to that, but never thought I could until I sa w Cynthia Wall's fi rst book. [read that and said ' Gee, I can do this.' And I pu t an outline together:' Casle r drew on his 'f-hu nting experiences at Bri gham Young University 10 complete his tal e of high school ham adventure. " I' d been interested in ham radio for years. but it wasn't until I was in cortege that I did something about it," he says. 'The clu b I was in had a 101 of 'l-hums. We thoroug hly enj oyed them. I thought they were the greatest thing." The Tompkins and Wall books are readily available in paperback from ham radio oealers, in addition to direct mail from ARRL.2 C indy Wall often goes 10 ham conventions and is invited to give talks in Oregon schools about ham radio and writing. O n the ot her hand, Ca sler's book has not been promoted by its publisher. You probab ly can' t find it in ham stores, hut it's available by mail order from MFJ. Stoc k number is MFJ-3101.1t is also available on the Wcb from Barnes and Noble.' So if it's lime to get a b irthday present for a g ra ndc hild . niece , nephew, or any o ther you ng person who s ho uld learn more about ham radio , con sider o ne o r more o f th e Wall, Tompkins and Casler book s . If i t ' s fo r an ad ult, c o nsi d e r Rebecca Gruenncr's hook . But be sure to do your shop ping early, so yo u' ll have the m in time 10 read yourself!

The last four days of the month show a pote ntial for so me of the largest so lar events of 200 2, so look fo r several C MEs and/or Xcclass flares. They co uld prod uce a large proton event between the 28th and 3 1st if any of them arc Earth-di rected .

Agai n, mueh of the globe should be workable during daylight hours. For best results, work from cas t to west a s thc day progresses.Try Europe before noon. Africa and the Middle East shortly after noon. and Ce ntral or South America after that. Late in the day you should pick up the South Pacific and other areas of the so uthern hemisphere for a few hours, but signals. will fade quickly after sunset. Check the morning and e vening gray-li ne paths ove r the pole s for contacts in Asia. Dayti me short-skip operate overdistances between 1.000 and 2.(1(0 miles. 15 and 17 meters
Excellent worl dwide openings. are likel y to be available with the best opportunities in the southern hemisphere. Europe will peak before noon. but most other areas don' t begin to open up until after mid-day. The best sig nals will still he from Ce ntra l and South America. but strong openi ngs can be found 10 both Africa and the South Pacific. Short skip will typically range from 1,000 10 2,000 miles. 20 meters Good DX can be expected all day, from sunrise through the evening hours. Peak periods will he shortly after sunrise . again in the late afte rnoo n, and someti mes in the
early evening. West and Central Afri ca can provide unusually strong signals at this time of year. so try to fill in some of the countries missing from your OX log. The same is true for the South Pacifi c and Asia. Short
These bands are finally coming into season with decent worldwide DXing available from sunset through sunrise. Tropical storms may still limit activity here. hut when they subside some strong European signals can be heard from the Ea st Coast. and strong South Pacific or New Ze aland stations can be picket! up fr om the West Coast.

This has worked o ut fabulously in India where there are groups providing micro-loans to people so they can start their o wn businesses. Warning'!
We're all aware of the co llapse of investments. First savings and loans, [hen c-companics. and now Enron, WorldCorn. et al. The Wilshire 51XlO, which tracks every publicly traded U.S. company, hit its peak in March 2000. Since then the market has lost over $7 trillion in value, and over a thousand major co mpanies have go ne o ut of business. That's 4 1% of the value of aJitraded stocks going pITt in 28 months! Alan Greenspan and Dubya assure us that our economy is sound. Wi th almost half our peop le 's savings gone, the sound I hear is an echo. An echo of 1929's
dull thud, when Hoo ver also ass ured the cou ntry thai the eco nomy was basica lly sound. Th is fiasco resulted in Roosevelt being elected in 1932, tak ing us off the gold standard so the Fed could issue all the paper it wanted on a "trust us" basis. trying to paper our way out of the depression. II took WWlI to fi nally get things moving again. I' m not sure how our mak ing trillions of dollars of war materials and destroying the m rebuilt our economy, but it did. We ll. it go t us used to having our taxes taken out of our paychecks instead of paying the go vernment off o nce a year. II got us used to so-called Social Security, where our money was also taken o ut of ou r paychecks so it co uld be immcdiatel y spent by Congress. replaced by their IOUs. They still haven 't explained where the money will come from to repay all those IOUs. But. at least they' re begi nning to worry abou t it. Thanks . We also got used to wives having to join the workforce so families could make ends meet. Today two family members working earn less in real do llars than o ne did before WW U. Okay. so what docs all this mean? Well, with a thousand companies out of business and the others busy downsizing. it's goi ng to be more and more difficult for wage earners to fi nd wage sources . With an average stock market loss of about $30.000 per family, people are obviously goi ng to be buying less stuff putting stuff manufacturers and retailers out of business. This could. at least. put a stop to the projected HDTV conversion and the year ly upgrading of personal compute rs.
The Iraq Stess Let's see now. are you in favor of our attacking Iraq and gelling rid of Saddam? Or do you think it's a had idea'! If you' vc read Black Ha wk Down (or seen the movie ), you' re unlikcly to be much in favo r of the war. Or you may have a firm belief in peace. With Saddam signing alliances with Syria and even Iran , and with o ur allies look ing away nervously when we ask them to joi n us. the situation is loo king messy. On the other hand, a recently defec ted Iraqi nuclear physicist testified that Saddam can be expected to have built two or three nukes within three years. And that's if he hasn' t already managed to buy a few from ex-USSR sources. Saddam 's next step is obvious . .. hide o ne in downt own Manhattan or Washington and threaten to use it if the U.S. causes him any trouble.

in the search, going 10 Nikumaroro Island. Another, Nauticos Corporation, plans 10 spend $3 million to $4 million searching the ocean bonom in the Howland Island area. Still anorheer. Dana Timmer's group, Head of Howl and Landing, Inc.. spent a million to hunt for the plant: in 1999. Whe n writer Fred Goerner researched Amelia 's disappe arance, a six year adventure which culminated in his book in 1966, he wcmto the islands where Amelia had been reported to have been seen. And he did this with the Navy obstructing him cverv inch of the way. A~ I' ve written before. Amelia was a good friend of my dad 's. She kept her Lockhee d at my dad's Central Airport. just across the river from Philadelphia and she had dinner at our house a couple times. In 1936 her chie f mechanic had dinner with us. explaini ng that he'd just I1n ished installing spec ial higher-powered engi nes. extra wing tanks. and cameras for her coming flight around the world. He said that President Roosevelt. who had been the Secretary of the Navy, had asked her to make a spy trip to take photos of the Japanese installation at Truk. Bv a coincidence, when I was at the submarine rest camp in 1944 on Majuro in the Marshall Is lands , the nati ves said that a plane had c rash-landed there seven vcars earlier. Th e woman pilot was unhun , but the man navigator had been in· j ured. They said a Japanese ship picked up the two and their plane and look them to Saipan. This was the same story Goerner heard when he interviewed the Maj uro natives about twenty years later. When my sub stopped oIT for a couple days at Saipan to refuel I had. an opportunit v to a...k the nari vcs there about Ameiia. They said that she' d been killed by the Japanese when the Americans were capturing the island , and that the Americans had burned her plane. Again, Goerner gut this same story when he visited Saipan. I corresponded with Goerner about all this at the time and. reponed it in my editorials. Why all the co v cr-up? Our government didn' t want 10 admit that the most famous woman in the world had been recruitcd by Roosevelt as a spy. And the Japanese didn' t want it kno wn that they'd executed the most famous woman in the world. Still don't. The next time you see a newspaper arMort.' Amelia ticle about fi nding Amelia's plane, clue in the writer for me. Oh. and send me a If these groups who want to fi nd copy of the clipping. Amelia Earhart 's plane would bother to do so me fairly simple investigation. 7\tort' Drug Nonsense they' d stop wasting their time and a Ion While vou were sleeping, the DEA's of money.

made for you o ne night. It 's eno rmously complicated and it has an unbelievably capable repair system built in. II 's able to convert a wide varie ty of fuel into heat and the building material for a lifetime of maintenance. So you si t down at a table, put food in your mouth. chew it. a nd swallow it. Case closed'! Hmr n. not quite. The fact is that there's this saliva stuff in your mouth which is a fundamental part of your digestive system. Chewing food j ust enough so you can swallow it win send it to the next part of the system before it's read y. Dr. Kellogg, a hundred years ago, had it right when he got people to chew every bite a hundred times before swallowing. C hc w everything thoroughly be fore you swallow, Give the saliva a chance to do its part in your digestive system. Yes, it takes longer 10 cat. I used to he a gap and swallo w eater; now when I'm in a restaurant other groups come in. order, get their meals, cat, pay their check and arc gone while I'm still si tt ing there chewing. Chew your food. What' s your damned hurry'? At home l listen to my tape of the previous night's Coast to Coast A rt Bell radio show and assemble the pages of my books while I'm chewing. Or I' m CUlting up fruit and vegetables for the next day. It takes a while to CUi a watermelon into six quart contui ncrs. Or cUI up some cantaloupes. oranges. and grapefruit. Okay, now lesson two. Once you've chewed every thing up in a saliva bath you send it o n to your stomach. Here it's doused with hydrochloric acid to fu rther dissolve that j unk you ate, mainly 10 satisfy your taste buds , and probably with lillie consideratio n for the fuel you should he supplying. So you pour down some water, tea. or coffee to dilute the acid so it can' t do its job properly and the food is then forwarded on dow n the chute in only partially digested form. This means that your intestines won' t be able to do their job of removing the nutrients right and the whole system is in trouble. Your bod y does need a whole lot more pure water than you've been giving it, but not at meal ti me. Give the food an hour before you start the deluge. Give your digestive system a break. okay?
