 religion or changed his name to that of his favorite baseball team。 He grew up in Brooklyn; you know。〃
 〃No;〃 said Jake Grafton through clenched teeth。 〃I didn't。〃
 〃Yeah。 Anyway; he's dabbled in puters and radar for years and patented this technology for suppressing reflected radiation。 He came to me with some technical problems。 I used my influence with the navy to get him a good radar to work with。 Had it delivered in a moving van。〃 He chuckled。 〃I'll tell you that story sometime。〃
 〃Henry says he's a genius。〃
 Fritsche nodded his agreement between drags on his cigar。 Smoke filled the interior of the car。 Jake cracked his window an inch to exhaust the thick fumes。 〃He'll probably be in the running for a Nobel when his achievements get declassified。〃
 〃Somebody said he's greedy。〃
 〃Samuel wants some bucks; all right。 I can't condemn him for that; not after a few years of reading about the pirates of Wall Street。 Dodgers is the founder and only benefactor of his church and he wants to take it nationwide; with TV and radio anil a hallelujah choir; the whole schema。 I think he realizes that since he's so heavy into hellfire and damnation; contributions are going to be light。 The feel…good; be…happy ministries are the ones rolling in the dough。 Dodgers is going to have to keep his afloat out of his own pocket。〃
 Jake Grafton arranged the collar of his civilian jacket around his neck and lowered the window another inch。 〃What did George Ludlow say when he heard about Dr。 Dodgers?〃
 〃Amen;〃 Fritsche said lightly。
 〃I believe it;〃 Jake muttered。 His panion tittered good…naturedly。
 The car rolled on into the farm district south of San Jose。 Eventually Fritsche turned up a dirt driveway and parked in front of a ramshackle wooden structure。 A large sign amid the weeds proclaimed: 〃Faith Apostolic Gospel Tabernacle。〃
 〃I think we ought to get down on our knees inside and pray the GAO never gets wind of this;〃 Jake said as he surveyed the weeds and the fading whitewash on the old structure。 The last coat of thin whitewash had been applied over a still legible Grange hall sign。
 〃You'll see;〃 Fritsche assured him。
 Samuel Dodgers was a stringy man in constant motion。 He stood in the small; dusty chapel and tugged at this; gestured at that; reset the Dodgers baseball cap on his balding dome for the hundredth time; pulled at his trousers or ear or nose or lower lip; moving; always moving。 〃So you fellows wanta see it again; huh; and see what progress looks like in the late twentieth century? When do I get some money?〃
 〃You got your last check two weeks ago。〃
 〃I mean the next one。〃 He hitched up his pants and reset his cap and looked from face to face expectantly。 The sunlight ing through a dirty windowpane fell on a long; lean face。 His chin jutted outward from almost nonexistent lips。 Above the grim mouth was a sharp nose and two restless black eyes。 〃The next check…when?〃
 〃I think it's a couple months away;〃 Fritsche replied gently。
 〃If I weren't a Christian I'd cuss you government people。 Your tax people squeeze the juice right out of a man…a man who's sitting on the biggest advancement in military technology since the horseshoe…but the giving hand is so all…fired parsimonious; stingy; miserly。 You people are just cheap!〃
 〃You're being paid according to the contract you agreed to; Dr。 Dodgers。〃
 〃Get a man over a barrel and squeeze him。 It's a sin to take advantage of a man trying to do the Lord's work like I am。 A an。〃
 Jake glanced at Helmut Fritsche。 He appeared unperturbed。
 Dodgers led them between a dozen or so folding chairs toward the door near the altar。 〃Praise the Lord and pass the ammunition;〃 Fritsche muttered just loud enough for Jake to hear above the tramping and scraping of heavy feet on the wooden floor。
 The back half of the old Grange hall was a well…lit workshop。 Several strings of naked hundred…watt bulbs were woven through the joists and cast their light on a crowded jumble of workbenches; tools and junk。 The visitors picked their way through it behind Dodgers; who approached the only person in the place; a young roan of about twenty with carrot…red hair and acne to match。
 〃My boy Harold;〃 Dodgers said to Jake; who shook the offered hand and introduced himself。 〃Harold was at Stanford; but they weren't teaching him anything; so he came back here to work with me。 Learn more here with me than he would in that Sodom of little minds。 Those fools with their calculators; always saying that something won't work。。。〃 He continued to fulminate as he opened the large doors at the back end of the building and began stringing electrical cords。 〃Well; Helmut; you seen this done before。 Don't just stand there like a tourist。〃
 Dodgers drew Jake aside as Fritsche and Harold hooked up electrical cords and moved a workbench outside。 〃Okay。〃 He cleared his throat 〃Over there on that little bench below those trees〃…he pointed at the side of a hill about a half mile away…〃is the radar。 Harold will run that。 That's the radar the navy loaned me。 Got it up there in an old two…holer that used to be here behind the tabernacle。〃 He stopped and showed Harold exactly how he wanted the power cables connected。
 Jake joined him at a workbench。 〃Now this little radar suppressor…it picks up the ining signal on these three antennas here and feeds it into this puter over there。 Got four of the fastest chips made in this thing…Harold did most of the puter design。 puters are his bag。 Little hobby of mine too。 Anyway; the puter analyzes the ining signal: strength; frequency; direction; PRF…that's Pulse Repetition Frequency…and so forth; and generates a signal that goes out through these panion antennas to muffle out future signals。 That's why these antennas are twins。 You have a receiver and a transmitter。〃
 〃But you can't suppress the first signal ing in?〃
 〃Nope。 They get one free look。 The very first ining pulse will not be muffled。 Nor; in this generation of this device; will the second。 See; you can't get a pulse repetition frequency until you have received at least two pulses; which you must have to time your outgoing pulses; the muffling pulses。 But with existing radars; the return from one pulse will be treated like static。 The cathode…ray tubes need a lot more pulses than that。〃
 〃And when the guy painting you stops transmitting; you beacon one more time?〃
 〃That's the problem Harold and I are working on right now。 You see; after the first pulse es in; and the second; the puter then has to figure it all out and start transmitting。 Right now we've got the puting time down to about ten billionths of a second。 That's not enough of a clean chirp to let any existing radar get a definable return。 If the next pulse doesn't arrive right on time; we'll stop the muffling pulses ten nanoseconds later。 Just need to fix the software; the XY dipole and。。。〃 His voice fell to an incoherent mumble。
 〃Why wouldn't a second radar that is in a receive…only mode see you beaconing to the first radar?〃
 〃Bistatic radar? It would;〃 said the genius in jeans; 〃if all we were doing was pulsing straight back at the transmitter。 But we aren't。 We're pulsing from a series of antennas all over the plane to neutralize the reflected signal。 Knowing how much to radiate; precisely enough yet not too much; that's where the puter really makes this thing work。 First you must know the exact reflective characteristics of the object you are trying to protect…that's your airplane…and put that data into the puter's memory。 Then the puter calculates the scatter characteristics of the ining signal and tells each of the two hundred transmitters positioned over the fuselage and wings and tail just how much to radiate。 All of the transmitters have to radiate in all directions。 And this whole thing has to work very; very quickly。 No puter was fast enough to handle this until superconductivity came along。 See; to make the electrical signals move along fast enough to make this work; I've had to super…cool my puter in a tank of liquid hydrogen and encase the wires to each of the antennas in this special sheathing。 That lowers the resistance just enough。〃 He gestured to a row of pressure bottles that stood in one corner of his worksho
