    To all the kids who survived the 1930’s, 40’s, 50’s, & 60’s

    Copied via email from a friend…

    First, we survived being born to mothers who may have smoked and/or drank while they were pregnant. They took aspirin, ate blue cheese dressing, tuna from a can, and didn’t get tested for diabetes.

    Then, after that trauma, we were put to sleep on our tummies in baby cribs covered with bright colored lead-based paints.

    We had no childproof lids on medicine bottles, locks on doors or cabinets, and, when we rode our bikes, we had baseball caps, not helmets, on our heads.

    As infants and children, we would ride in cars with no car seats, no booster seats, no seat belts, no air bags, bald tires and sometimes no brakes.

    Riding in the back of a pick-up truck on a warm day was always a special treat.

    We drank water from the garden hose and not from a bottle.

    We shared one soft drink with four friends, from one bottle, and no one actually died from this.

    We ate cupcakes, white bread, real butter, and bacon. We drank Kool-Aid made with real white sugar. And we weren’t overweight. WHY?

    Because we were always outside playing…

    We would leave home in the morning and play all day, as long as we were back when the streetlights came on. No one was able to reach us all day.

    We would spend hours building our go-carts out of scraps and then ride them down the hill, only to find out we forgot the brakes. After running into the bushes a few times, we learned to solve the problem.

    We did not have PlayStations, Nintendos and Xboxes. There were no video games, no 150 channels on cable, no video movies or DVDs, no surround-sound or CDs, no cell phones, no personal computers, no Internet and no chat rooms.

    We had friends and we went outside and found them!

    We fell out of trees, got cut, broke bones and teeth, and there were no lawsuits from those accidents.

    We would get spankings with wooden spoons, switches, ping-pong paddles, or just a bare hand, and no one would call child services to report abuse.

    We ate worms, and mud pies made from dirt, and the worms did not live in us forever.

    We were given BB guns for our 10th birthdays, made up games with sticks and tennis balls, and, although we were told it would happen, we did not put out very many eyes.

    We rode bikes or walked to a friend’s house and knocked on the door or rang the bell, or just walked in and talked to them.

    Little League had tryouts and not everyone made the team. Those who didn’t had to learn to deal with disappointment.

    The idea of a parent bailing us out if we broke the law was unheard of. They actually sided with the law!

    These generations have produced some of the best risk-takers, problem solvers, and inventors ever.

    The past 50 to 85 years have seen an explosion of innovation and new ideas.

    We had freedom, failure, success and responsibility, and we learned how to deal with it all.

    If YOU are one of those born between 1925-1970, CONGRATULATIONS!

    You might want to share this with others who have had the luck to grow up as kids before the lawyers and the government regulated so much of our lives for our own good.

    While you are at it, forward it to your kids, so they will know how brave and lucky their parents were.

    Kind of makes you want to run through the house with scissors, doesn’t it?

    The quote of the month by Jay Leno:

    “With hurricanes, tornadoes, fires out of control, mud slides, flooding, severe thunderstorms tearing up the country from one end to another, and with the threat of bird flu and terrorist attacks, are we sure this is a good time to take God out of the Pledge of Allegiance?”

    Close your eyes and use your imagination…

    I’ve been a fan of radio shows for years, dating back to when I was introduced to them by a friend in high school. If I remember correctly, Sean introduced me to “The Hitchikers Guide to the Galaxy” first, then series like “Now Nordine“, “The Cabinet of Doctor Fritz”, and “A Prairie Home Companion.”

    It was just incredible to turn out the lights, climb into bed, close my eyes and get lost in the sounds and characters from these stories and performances.  One of my favorites was Jack Flanders.  The background sounds in this series were recorded live in the locations they described.  You can hear and feel just like you were standing right there with the characters as the events happen.

    The ZBS Foundation, who produces the Jack Flanders series, describes it this way; “Jack Flanders is an adventurer. He not only travels to different countries in search of knowledge, he also steps into other dimensions to solve strange metaphysical puzzles. All of Jack’s stories have a lightness and humor, as well as some wonderful little wisdoms scattered throughout.

    “Jack Flanders’ adventures are often set in locations where we traveled to record the sounds; Brazil, the Amazon, India, Bali, Java, Sumatra, Belize, Costa Rica, Morocco, Montreal and New Orleans.”

    There are a number of Jack Flanders’ adventures:

    All I can really add is that it is truly amazing how these stories can entertain and spur the imagination.  Movies and TV can accomplish much, but your imagination can do so much more…

  • A Technical ‘Twas the Night Before Christmas’

    A Technical ‘Twas the Night Before Christmas’

    This gives me a headache…

    ‘Twas the Night Before Christmas’ as written by a technical writer for a firm that does Government contracting…

    Twas the nocturnal segment of the diurnal period preceding the annual Yuletide celebration, and throughout our place of residence, kinetic activity was not in evidence among the possessors of this potential, including that species of domestic rodent known as Mus musculus. Hosiery was meticulously suspended from the forward edge of the wood burning caloric apparatus, pursuant to our anticipatory pleasure regarding an imminent visitation from an eccentric philanthropist among whose folkloric appellations is the honorific title of St. Nicholas.

    The prepubescent siblings, comfortably ensconced in their respective accommodations of repose, were experiencing subconscious visual hallucinations of variegated fruit confections moving rhythmically through their cerebrums. My conjugal partner and I, attired in our nocturnal head coverings, were about to take slumberous advantage of the hibernal darkness when upon the avenaceous exterior portion of the grounds there ascended such a cacophony of dissonance that I felt compelled to arise with alacrity from my place of repose for the purpose of ascertaining the precise source thereof.

    Hastening to the casement, I forthwith opened the barriers sealing this fenestration, noting thereupon that the lunar brilliance without, reflected as it was on the surface of a recent crystalline precipitation, might be said to rival that of the solar meridian itself – thus permitting my incredulous optical sensory organs to behold a miniature airborne runnered conveyance drawn by eight diminutive specimens of the genus Rangifer, piloted by a minuscule, aged chauffeur so ebullient and nimble that it became instantly apparent to me that he was indeed our anticipated caller. With his ungulate motive power travelling at what may possibly have been more vertiginous velocity than patriotic alar predators, he vociferated loudly, expelled breath musically through contracted labia, and addressed each of the octet by his or her respective cognomen – “Now Dasher, now Dancer…” et al. – guiding them to the uppermost exterior level of our abode, through which structure I could readily distinguish the concatenations of each of the 32 cloven pedal extremities.

    As I retracted my cranium from its erstwhile location, and was performing a 180-degree pivot, our distinguished visitant achieved – with utmost celerity and via a downward leap – entry by way of the smoke passage. He was clad entirely in animal pelts soiled by the ebony residue from oxidations of carboniferous fuels which had accumulated on the walls thereof. His resemblance to a street vendor I attributed largely to the plethora of assorted playthings which he bore dorsally in a commodious cloth receptacle.

    His orbs were scintillant with reflected luminosity, while his submaxillary dermal indentations gave every evidence of engaging amiability. The capillaries of his malar regions and nasal appurtenance were engorged with blood which suffused the subcutaneous layers, the former approximating the coloration of Albion’s floral emblem, the latter that of the Prunus avium, or sweet cherry. His amusing sub- and supralabials resembled nothing so much as a common loop knot, and their ambient hirsute facial adornment appeared like small, tabular and columnar crystals of frozen water.

    Clenched firmly between his incisors was a smoking piece whose grey fumes, forming a tenuous ellipse about his occiput, were suggestive of a decorative seasonal circlet of holly. His visage was wider than it was high, and when he waxed audibly mirthful, his corpulent abdominal region undulated in the manner of impectinated fruit syrup in a hemispherical container. He was, in short, neither more nor less than an obese, jocund, multigenarian gnome, the optical perception of whom rendered me visibly frolicsome despite every effort to refrain from so being. By rapidly lowering and then elevating one eyelid and rotating his head slightly to one side, he indicated that trepidation on my part was groundless.

    Without utterance and with dispatch, he commenced filling the aforementioned appended hosiery with various of the aforementioned articles of merchandise extracted from his aforementioned previously dorsally transported cloth receptacle. Upon completion of this task, he executed an abrupt about- face, placed a single manual digit in lateral juxtaposition to his olfactory organ, inclined his cranium forward in a gesture of leave-taking, and forthwith effected his egress by renegotiating (in reverse) the smoke passage.

    He then propelled himself in a short vector onto his conveyance, directed a musical expulsion of air through his contracted oral sphincter to the antlered quadrupeds of burden, and proceeded to soar aloft in a movement hitherto observable chiefly among the seed-bearing portions of a common weed. But I overheard his parting exclamation, audible immediately prior to his vehiculation beyond the limits of visibility: “Ecstatic Yuletide to the planetary constituency, and to that self-same assemblage, my sincerest wishes for a salubriously beneficial and gratifyingly pleasurable period between sunset and dawn.”

  • Child Logic

    Child Logic

    Had a friend send me these…

    1. She was in the bathroom, putting on her makeup, under the watchful eyes of her young granddaughter, as she’d done many times before. After she applied her lipstick and started to leave, the little one said, “But Gramma, you forgot to kiss the toilet paper good-bye!” I will probably never put lipstick on again without thinking about kissing the toilet paper good-bye….

    2. My young grandson called the other day to wish me Happy Birthday. He asked me how old I was, and I told him, 62.  My grandson was quiet for a moment, and then he asked,  “Did you start at 1?”

    3. After putting her grandchildren to bed, a grandmother changed into old slacks and a droopy blouse and proceeded to wash her hair.. As she heard the children getting more and more rambunctious, her patience grew thin. Finally, she threw a towel around her head and stormed into their room,  putting them back to bed with stern warnings. As she left the room, she heard the three-year-old say with a trembling voice, “Who was THAT?”

    4. A grandmother was telling her little granddaughter what her own childhood was like: “We used to skate outside on a pond I had a swing made from a tire; it hung from a tree in our front yard. We rode our pony. We picked wild raspberries in the woods.” The little girl was wide-eyed,  taking this all in. At last she said, “I sure wish I’d gotten to know you sooner!”

    5. My grandson was visiting one day when he asked, “Grandma, do you know how you and God are alike?” I mentally polished my halo and I said, “No, how are we alike?” “You’re both old,” he replied.

    6. A little girl was diligently pounding away on her grandfather’s word processor. She told him she was writing a story. “What’s it about?” he asked. “I don’t know,” she replied. “I can’t read.”

    7. I didn’t know if my granddaughter had learned her colors yet, so I decided to test her. I would point out something and ask what color it was. She would tell me and was always correct. It was fun for me, so I continued.. At last, she headed for the door, saying, “Grandma, I think you should try to figure out some of these, yourself!”

    8. When my grandson Billy and I entered our vacation cabin,  we kept the lights off until we were inside to keep from attracting pesky insects. Still, a few fireflies followed us in.  Noticing them before I did, Billy whispered, “It’s no use Grandpa.  Now the mosquitoes are coming after us with flashlights.”

    9. When my grandson asked me how old I was, I teasingly replied, “I’m not sure.”  “Look in your underwear, Grandpa,” he advised, “mine says I’m 4 to 6.”

    10. A second grader came home from school and said to her grandmother, “Grandma, guess what? We learned how to make babies today.” The grandmother, more than a little surprised, tried to keep her cool. “That’s interesting,” she said,  “how do you make babies?”  “It’s simple,” replied the girl. “You just change ‘y’ to ‘i’ and add ‘es’.”

    11. Children’s Logic: “Give me a sentence about a public servant,” said a teacher. The small boy wrote: “The fireman came down the ladder pregnant.” The teacher took the lad aside to correct him. “Don’t  you know what pregnant means?” she asked.  “Sure,” said the young boy confidently. ‘It means  carrying a child.”

    12. A grandfather was delivering his grandchildren to their home one day when a fire truck zoomed past.  Sitting in the front seat of the fire truck was a Dalmatian dog.  The children started discussing the dog’s duties. “They use him to keep crowds back,” said one child. “No,” said another. “He’s just for good luck.” A third child brought the argument to a close.”They use the dogs,” she said firmly, “to find the fire hydrants.”

    13. A 6-year-old was asked where his grandma lived. “Oh,” he said, “she lives at the airport, and when we want her, we just go get her. Then, when we’re done having her visit, we take her back to the airport.”

    14. Grandpa is the smartest man on earth! He teaches me good good things, but I don’t get to see him enough to get as smart as him!

    15. My Grandparents are funny, when they bend over; you hear gas leaks, and they blame their dog.

  • Satellite Terminology

    Satellite Terminology

    Here’s some basic information to get you started with satellite operations…with my thanks to the many different sources from which it has been gathered around the Internet including AMSAT and Stephen Holmstead, N7TQL, for use of the information contained in the HAM Satellite FAQ.

    Definitions

    • AMSAT – It is a registered trademark of the Radio Amateur Satellite Corporation, a non-profit scientific/educational organization located in Washington, DC that builds and operates Amateur Radio satellites.
    • Attitude – Position of a craft in space; determined by the inclination of its axis to a fixed reference point on the Earth.
    • Apogee – Point in an Earth orbit where an orbiting body is farthest from the earth.
    • Argument of perigee – The polar angle that locates the perigee (point where the satellite is CLOSEST to the earth) point of a satellite in the orbital plane; drawn between the ascending node, geocenter, and perigee; and measured from the ascending node in the direction of satellite motion.
    • Ascending node – The point on the ground track of the satellite orbit where the sub-satellite point (SSP) crosses the equator from the Southern Hemisphere into the Northern Hemisphere. Traveling from South America up (ascending) to North America.
    • Azimuth – Direction (side-to-side in the horizontal plane) from a given point on Earth, usually expressed in degrees. North = 0 or 360 degrees; East = 90 degrees; South = 180 degrees; West = 270 degrees.
    • Beacon – Most satellites have a fixed Morse beacon at the lower end of the satellites band-pass transponder. This is useful to detect when the satellite has crossed the horizon and is in range for operation. It can also be used to determine Doppler shifts.
    • BBS – An electronic Bulletin Board System which users can use to leave and retrieve messages.
    • Cosmic Speed – Five miles per second, the velocity required to put a satellite in Earth orbit; called first cosmic speed.
    • Drag – Air resistance to a body in flight.
    • Descending node – The point on the ground track of the satellite orbit where the sub-satellite point (SSP) crosses the equator from the Northern Hemisphere into the Southern hemisphere. Traveling from Canada DOWN (descending) towards South America.
    • Doppler effect – Apparent frequency change of waves which results when the source and recipient of the waves move toward, and then away, from each other. A shift in frequency caused by satellite movement toward or away from your location. When the satellite is coming toward you, the Doppler shift decreases the frequency. When the satellite is going away from you, the frequency increases. Like the waves from the ocean piling up in front of a storm.
    • Downlink – The frequency which the satellite transmits to the Earth for reception by stations on Earth.
    • Eccentricity – The orbital parameter used to describe the geometric shape of an elliptical orbit; eccentricity values vary from e = 0 to e = 1; where e = 0 describes a perfect circle and e = 1 describes a straight line. The amount a spacecraft deviates from a circular orbit.
    • Ephemeris – Table indicating the computed positions of celestial bodies from day to day or at regular intervals throughout the year.
    • Elliptical Orbit – Those orbits in which the satellite path forms an ellipse with the Earth at one focus.
    • Epoch – The reference time at which a particular set of parameters describing satellite motion (Keplerian elements) are defined. The particular time the elements were produced.
    • Equatorial orbit – Earth orbit with a plane near or identical to that of the equator.
    • Geocenter – The center of the Earth.
    • Geostationary orbit – A satellite orbit at such an altitude (approx. 22,300 miles) over the equator that the satellite appears to be fixed above a given point. The satellite must also travel in the direction of the earth’s rotation. The satellite remains in the same spot day after day, year after year.
    • Ground Station – A radio station, on or near the surface of the earth, designed to transmit or receive to/from a spacecraft.
    • Groundtrack – The imaginary line traced on the surface of the Earth by the subsatellite point (SSP).
    • Inclination – The angle between the orbital plane of a satellite and the equatorial plane of the Earth.
    • Keplerian Elements – The classical set of six orbital elements numbers used to define and compute satellite orbital motions. The set is comprised of inclination, Right Ascension of Ascending Node (RAAN), eccentricity, argument of perigee, mean anomaly and mean motion, all specified at a particular epoch or reference year, day, and time. A decay rate or drag factor is usually included to refine the computation.
    • Kepler, Johannes – (1571-1630) German astronomer who determined the periods of revolution of the planets. Created “Kepler’s laws” which read: 1) The path of every planet in its motion about the sun forms an ellipse, with the sun at one focus (see Elliptical orbit). 2) The speed of a planet in its orbit varies so that a line joining it with the sun sweeps over equal areas in equal times. 3) The squares of the planets’ periods of revolution are proportional to the cubes of the planet’s mean distances from the sun. Kepler was very active in astronomy throughout his whole life. He was once the astrologer and astronomer to Rudolph II of Bohemia. He also corresponded with Galileo and Tycho Brahe while at the university of Graz, Austria. In 1600 Kepler became Tycho’s assistant in Prague. Kepler’s laws removed all doubt that the earth and planets go around the sun. Later Newton used Kepler’s laws to establish his law of universal gravitation. Kepler also invented the present-day form of the astronomical telescope.
    • Mean anomaly – An angle that increases uniformly with time, starting at perigee, use to indicate where a satellite is located along its orbit. MA is usually specified at the reference epoch time where the Keplerian elements are defined. For AO-10 the orbital time is divided into 256 parts, rather than degrees of a circle, and MA (sometimes called Phase) is specified from 0 to 255. Perigee (closest to Earth) is therefore at MA = 0 and apogee (farthest away from Earth) is at MA = 127.
    • Mean motion – The Keplerian element (a number) to indicate the complete number of orbits a satellite makes in one day. (ie. 14.00374 orbits per day)
    • Mode A – This mode requires a 2M SSB/CW transmitter and a 10M SSB/CW receiver and supports CW and voice.
    • Mode B – This mode requires a 70cm SSB/CW transmitter and a 2M SSB/CW receiver and supports CW and voice. Some satellites also support RTTY and SSTV in this mode.
    • Mode K – This mode requires a 15M SSB/CW transmitter and a 10M SSB/CW receiver and supports CW and voice. This mode is unique in that it can be done with a simple HF rig.
    • Mode JA – This mode stands for J Analog and requires a 2M SSB/CW transmitter and a 70cm SSB/CW receiver and supports CW and voice.
    • Mode JD – This mode stands for J Digital and requires a 2M FM transmitter and a 70cm SSB/CW receiver and supports packet.
    • Mode S – This mode requires a 70cm SSB/CW transmitter and a 2.4Ghz SSB/CW receiver and supports CW and voice. Many people use a 2.4Ghz to 2M converter with a 2M SSB/CW receiver instead of buying a 2.4GHz SSB/CW receiver.
    • Mode T – This mode requires a 15M SSB/CW transmitter and a 2M SSB/CW receiver and supports CW and voice.
    • Nodal period – The amount of time between two successive ascending nodes of a satellite orbit.
    • Orbital elements – See Keplerian elements.
    • Orbital plane – An imaginary plane, extending throughout space, that contains the satellite orbit.
    • OSCAR – Orbiting Satellite Carrying Amateur Radio.
    • Pass – An orbit of a satellite.
    • Passband – The range of frequencies handled by a satellite translator or transponder.
    • Perigee – The point in a satellite’s orbit where it is CLOSEST to Earth.
    • Period – The time required for a satellite to make one complete revolution about the Earth.
    • RAAN – Right Ascension of Ascending Node. The Keplerian element specifying the angular distance along the celestial equator, between the vernal equinox and the ascending node of a spacecraft. This can be simplified to mean roughly the longitude of the ascending node.
    • Repeater – This closely resembles a land-based repeater. It listens for signals on one frequency and retransmits it on another frequency. All satellite repeaters (and transponders) are full duplex, meaning you can (and should) listen to you signal on the downlink (with headphones) while you are transmitting.
    • Satellite pass – Segment of orbit during which the satellite “passes” nearby and in range of a particular ground station.
    • SSP – Subsatellite point. Point on the surface of the Earth directly between the satellite and the geocenter (center of the Earth).
    • Telemetry – Radio signals, originating at a satellite, that convey information on the performance or status of onboard sub-systems. Also refers to the information itself.
    • Transponder – A transponder is a band-pass repeater, a device onboard a satellite that receives radio signals in one segment of the spectrum (band), amplifies them, translates (shifts) their frequency to another segment of the spectrum and retransmits them. It accepts a range of frequencies on the input and retransmits the entire range on the output. All offsets within that range are preserved.
    • Uplink – The frequency at which signals are transmitted from ground stations to a satellite. The signal you transmit to a satellite.
