Captain Robert de Baudricourt, a military squire, handsome and physically energetic, but with no will of his own, is disguising that defect in his usual fashion by storming terribly at his steward, a trodden worm, scanty of flesh, scanty of hair, who might be any age from 18 to 55, being the sort of man whom age cannot wither because he has never bloomed.

Although much of th is article has foc used on the FM broadcast band.
Although emphasis is often placed on peak dates, many showers last for several days. For these showers, detection should be attempted on several days. The directions listed in the Optimum Path columns indicate the directions from which signals can be received at your location. The times in these columns should be considered as broad guidelines only. I rthere is one. There will he no unoccupied channe ls tu mon iwr.

For tlwse who want a11 anlemia with a little gain, the 3-elemenl collinear c can be used. This is based the use of 14 solid or stranded wire although other sizes can be used.
If the antenna impedance Zr and the receiver input lo match, you won 't need the balun. Although lower frequenc ies would produce longer echoes and hi gher ampli tude echoes.
While frequencies above 50 MHz have the advantage of smaller antenna size, these higher freque ncies arc subject to higher path loss. In one system. When a meteor trai l appears, the remote site senses the renected signal and it in turn transmi ts a burst of data.
Amateur radio operators have played a major role in meteor communications and many sti ll attempt communications via meteors. In the past. That is, one station would repeated ly se nd a message and the receiving station wou ld piece together the informat io n unt il thecontacteould be confi rmed. Recently however. A liule practice with s poradic meteors and the Orionid meteor shower wi ll prepare you fo r the poss ibili ty o r a spectacular show during the Leonids over the next few years.

Thi s fall and winter, I will attempt several me teoractivities with the assistance of Ontario OX Association membe rs. You can try some on your own or help us with ours by liste ning for our signal and sending re ports.
You can start by mon itoring sporad ic meteors. You can record the reflected s ignals on audio tape, stripe hart pa per, or your computer. You can tht:n prodm:e your own graphs of daily mean hourly rates of reflected signals. A variati on of this is to produce a graph of average monthl y median echoes per hour. AN Similarly, you can select a meteor s hower and dett:rmine lhc average hourly rate at wh ich you detect me teors during the shower.
This information can stand on its own or be compared to the daily mean hourly rate for sporadic meteors. My planned activities include detecting meteor whistles.
EST during October. As with the experiment conducted by V illard, Manning, and Peterson at Stan ford Uni vers ity, lhe output of lhe transmitter wi ll feed a half-wave dipole. A similar dipole wi ll be used at the receiver site several ki lometers away. Although we will be li ste ning for whi stles, we will welcome reports from anyone who hea rs the signal.
We will also be transmitting du ri ng several meteor showers. Dcdination :just as you can locate any point on Eanh by specifying its longitude and latitude, you can locate a star or in the case of meteor showers, a radiant by specifying the ri ght ascension a nd dec lination on the celestial sphe re. Right ascension is given in hours and m inutes; declination is g iven in degrees. For example, fo r the Leonid meteor show, the right ascension a is! Duration: most meteor showers last for several days.
Meteor: the streak of li ght and related phenomena such as ion ization produced when a meteoroid e nters Earth' s atmosphe re Meteoroid: a n interplanetary particle which may be as small as g or as large as g. Meteor stream: a group of meteoroids traveling in high ly correlated orbits parallel paths ac ti v ity will take place during the Geminids December A poss ibl e meteor shower activity w hi ch we will undertake and which you can attempt as well is to set up two beam antennas preferably narrow-beam ante nnas pointing at the horizon.
As Earth rotates, a large number of echoes will first appear in Antenna I indicating the presence of a group of meteors the shower. As Earth conti nues to rotate, acti vity in Ante nna 1 wi ll diminish and echot:s will be heard in A ntenna 2. The transfer of activity from Antenna 1 to Antenna 2 confirms the ex istence of the meteor s tream. Th is method was used primaril y for studies of major showers, such as the Pe rseids or the Geminids.
They are closely related however. Planisphcrc: a chart of the sky showing the location of stars and constell ations. The chart has a clear. The effect is sim il ar to para lle l railway tracks thal appear to meet in the distance. The meteor shower is usuall y named for the constellation in w hic h the rad iant is located.
Forexample, the Leon ids' rad iant is in the l:onstellation Leo: the Perseids' radiant is in the constellation Perseus. With today' s EMS syste m in place.

Even d iret:t sate llite li ste ners may o bj ec t to the m ulti -lingua l approat:h. Swiss Radio International took the ambitious route. It was easy to set up 24 hour satell ite channe ls in the country's national languages, German.
French, and Itali a n. But S RI expanded its English programming as well into a 24 hour operati on. Most smalle r stations couldn ' t afford that kind of expansion. T he solution. The idea was obvious; the only proble m was doing it , considering the nature of European public broadcasting.
Large media bureaucracies just coul dn't work together that way. The " Ga ng of Four" o f Radio Netherlands.
Rad io Sweden, Radio Canada International, and Swiss Radio International discussed the idea, but couldn 't agree on its implementation. The European Broadcasting Union belatedly set up a spec ial forum for international broadcasters, which also ta lked about the concept.
Who would run the system? Who would decide who got to broadcast in prime time? How would be costs be di vided up? Who would pay for lines to the uplink site? The re were lots of questions, and no experience in actually working together on that le vel. They got UPI to provide temporary fac ilities by doing some work for the m, and talked British Sky Broadcasting into providing a free sound c hannel as a test.
For a week stations from all over Europe, and as fa r away as Is rae l a nd India, s hared a common satellite c hannel. The s igna ls poured into a tiny room at UPJ 's headquarte rs in London's Doc klands by sate llite link. It looked li ke c haos with cables running everywhere into equipment just patched together for the week, but it worked.
Some weeks later, supported by a contrac t from National Public Radio to bring its programs to Europe, WRN Network One we nt on the air on Astra, re lay ing some 20 international broadcaste rs. That was foll owed by a second channel, WRN 2, which turned things inside out by carrying program s in various stations' native languages for their nationals in North America. C-SPAN has re layed international broadcasters on its Secondary Audio Programs fo r several year: one c hannel for the BBC World Service, another for a varlet y of stat ions, most of which have been avai lable in Nort h America via some satell ite re lay.

Call your SGC dealer now for details. SGC Bu1h. Box That" s worked on shortwave. But numerous complaints about the repeats have come in from the Canadian night owls. More rece ntl y. WRN has expanded to Africa and Asia. The African service is on Intelsat A deal similar to that with CBC Overnight has been worked out.
The Asian service is part of a package of European radi o broadcasters on Asiasat Both the Afri can and Asian re lays differ from those to Europe and North America in that they are digital. That means right now the average home listener can' t tune in.
Instead they are intended for local and cable rebroadcasts. I've de voted a lot of space to the World Rad io Network story. There's simply nothing better right now. The larger broadcasters. However, both continue to provide programming on WRN as well.
But the comi ng digital age in broadcasting will see new stations that have never used an y other medium. Europe is just introducing Digital Audi o Broadcasting. The first regular transmissions began in September l in Britain and Sweden. Denmark, Norway. Germany, France, and Belgium have all followed suit. Ultimately, DAB receivers wi ll pick up transmissions from both terrestrial and satell ite transmitters. In preparati on forth is. Radio Net herlands.
Right now the co-operation involves a number of weekly programs called Radio E carried on sate llite and short wave by the stations involved. German, and French lhat would run on DAB channels in each of the participating countries. This goal seems rather remote, as DAB spectrum wi ll he limited until the FM band is phased out after the tu rn of the cent ury: most countries wi ll be fill ing their current DAB allocations with their own stations and are unl ikely to make room for Radio E.
One new digital international radio project is defin ite ly moving forward. Each wi ll provide digi tal audio channels to the entire coverage area. The first satellite to be launched will be AfriStar in June on Ariane. It will be followed at six month interva ls by AsiaStar and AmeriStar.
All three are being made by Alacatel Espace of France. The plan depe nds on the deve lopment of affordable receivers. By using economies of scale. These would be truly portable, with antennas the size of credit cards. WorldSpacc and similar projects may be a threat to traditional tropical band DXing.
