LOST - Where Is That Transmitter?

Radio Direction Finding (DF) is not something that is impossible to do. In fact is it is a big hobby for some people. Check out the page of of Amateur Radio Direction Finding enthusist, Joe Moell. I was amused by the strange efforts of Sayid on this week's LOST. If the transmitter is not moving, take a line of bearing (LOB), move and get another LOB. Better record these some how, maybe on a map. Pretty soon you can see where all the LOBs intersect and you have a FIX. The FIX is an area where the transmitter probably is. (Sometimes you get it wrong.) Its the same principle of resection with a compass. Equipment that automatically figures the FIX is three or more recievers taking reading togethers. The LOB from one radio is transmitted to a station that calculates where the FIX was on a computer.

1. Where was the map, electronic or paper, that was going to be used for the DF?

2. How were these walkie-talkie radios going to transmit their data? If you could transmit data, what was it going to transmit? Sayids radios could show a general LOB, but there was nothing that he was carrying that could figure a FIX through automation.

3. How were they calculating the location of the radios with no maps? Maps are key to DF.

4. By the way, they do need to find that French transmitter because it has an awesome power source. What is powering that thing?

With no map and radios that just showed the highest power reading of the reciever, probably one would be better off just walking, take a reading and walk and take a reading. Soon you it would be able to find the strongest LOB and start walking it. Recheck occationally to keep you on course. If you find the strongest signal behind you, you just passed it!

Was the New Testament Letters Only Written to Male Brothers?

  Question:   Was the Bible written to men only and not to women?   Some teach that the New Testament letters address brothers exclusively.      Executive Summary Answer:   Women and men share in the blessings of the gospel, Scripture was written for both women and men. So God created man in his own image, in the image of God he created him; male and female he created them. (Gen. 1:27 ESV) Answer:   The Bible recognizes differences between genders but also recognizes the commonality between male and female genders.   The book of Proverbs is written to sons to gain wisdom.   “Hear, my son, your father's instruction, and forsake not your mother's teaching, for they are a graceful garland for your head and pendants for your neck.”   (Prov. 1:8-9 ESV) The book of Proverbs was written in order to teach young men wisdom.   Even so, often it is the female gender that teaches wisdom.   Early in the book, the male gender, a son, is to embrace the teaching from a member of the

In The Hours Words by Helen L. Parmelee Music by Kevin Twit http://www.igracemusic.com/hymnbook/lead/inthehours.pdf This song by Indelible Grace is one that really moves me. I think it moves me because it reminds me of my own story. The words remind me of God's work in my life through the blessing of suffering. A lot of my best days walking with my Lord has actually been days of suffering. Verse one reminds me of growing up when I felt rejected by others but God was my song. 1. In the hours of pain and sorrow, When the world brings no relief When the eye is dim and heavy, And the heart oppressed with grief While blessings flee, Savior Lord we trust in Thee! While blessings flee, Savior Lord we trust in Thee! Verse two talks about my drifting from the Lord when I was caught up in pride and the sin of self-sufficiency. 2. When the snares of death surround us, Pride, ambition, love of ease Mammon with her false allurements, Words that flatter, smiles that please Then ere we yield, S

Celtic Words In English

I once heard a lecturer say that English was made up at its heart three languages; Anglo-Saxon (A Germanic tongue), French (influence from William the Conquerer A.D. 1066), and Latin (from the church and scholars). She also mentioned that Celtic had been the language of England before the influence of the Anglo-Saxons and some “tie together words” had been brought into English. I assumed she meant words which tie sentences together, or nouns. But I was not sure which words she meant in particular. So I did a little research to find out what those relics in our language are. It seems that Celtic has few words surviving in English. I'm not counting the Celtic words which came in through other languages such as French. I'm not sure that there is a definitive list of Celtic words in English but here are a few I found in various places on the Internet and a book I have. ass (borrowed earlier by the Celts from the Latin asinus) bannock bard blarney bucket car cart clock coll
