Articles and reviews from Zach

Notice: this is an article I published last year in Greek about the American digital radio in a greek web site. The theme is also on the page: http://zlgr.multiply.com/reviews/item/27 HDFM – HD radio Η αντιπρόταση το ψηφιακού ραδιόφωνου στην ΗΠΑ Το HD radio σχεδιάστηκε σαν μια επέκταση της υπάρχουσας τεχνολογίας ετσι ώστε να είναι απολύτως συμβατή με τα σημερινά ραδιόφωνα AM και FM και να προσφέρει πέρα από την υψηλή ποιότητα ήχου εφάμιλλη με τα CD την ικανότητα να ανθίσταται σε περιπτώσει ανωμαλίας της διάδοσης από ανακλάσεις (πχ σε βουνα όταν πχ χρησιμοποιείται στα αυτοκίνητα το σήματα να ακούγεται πάντα σαν να ήταν δηλ σταθερό ) Αυτή ήταν από την αρχή η φιλοσοφία το HD. Το σχεδιασμό και την μελέτη ανέλαβε η εταιρία Ιbiquity , προϊόν συγχώνευσης των εταιριών Lucent (εταιρία που ασχολείται και με δορυφορικά συστήματα εκπομπής ) και της Westinghouse Οι περισσότεροι μεταφράζουν τον όρο HD σε High Definition.

Notice: The times listed here are UTC (ie 2 hours less than the local time ) As you might see from my last year’s posting , the New year's eve , was with much of radio , DXing and satellite TV watching then visiting the waited but not realized , festival of New year on the centre of Thessaloniki This year was quite different than last year. At first , I was working this year until 1200 o clock but really there was really nothing special on office and local buildings were vacant from people. This is what we call in Greece , ‘we and the walls‘. Waiting to take my parents from the house , located nearby, (ca 1 km far from my work place) I asked my father who was outside , what they could do. He advised me to leave and return my home , as I did . My wife was waiting for me there. Last year’s eve we both were not at work At the other site , I already knew that nothing would be done on the night with the festical. Instead of it , the festival started fr...
