________________________________ This week's Surfin' considers Web sites where Amateur Television (ATV) is going digital. ________________________________ What Exactly Is 8-Vsb Anyway? http://www.broadcast.net/~sbe1/8vsb/8vsb.htm answers many of your questions concerning digital television. If you watched television during the past months, you could not miss the barrage of announcements concerning the switch from analog to digital broadcasting over the airwaves that will occur next year on February 17. If you use an analog television to receive broadcast signals over the air and not from a satellite, cable, or telephone company, then you will need a converter to receive broadcasts after Presidents' Day 2009. David Sparano has written an excellent article, http://www.broadcast.net/~sbe1/8vsb/8vsb.htm"What Exactly Is 8-Vsb Anyway?", that according to Nick Sayer, N6QQQ, has the best and most accessible description of 8VSB (8-level vestigial sideband modulation) that he has ever found. Nick is working on setting up an 8VSB transmitter. His goal is to get as close to an ATSC (Advanced Television Systems Committee)-compatible ATV station as he can get. Hhe recommends the article to anyone who wants to get started in digital ATV. By the way, Nick has a Web page http://www.kfu.com/~nsayer/ and a blog where you can read about his adventures in ATV. Another by the way -- if you search the Internet for digital ATV information, you will find European Web sites dedicated to the topic, but note that Europeans use DVB (Digital Video Broadcasting) Standards that North American television receivers cannot demodulate. Until next time, keep on surfin'! Page last modified: 08:00 AM, 03 Oct 2008 ET Page author: [EMAIL PROTECTED] Copyright © 2008, American Radio Relay League, Inc. All Rights Reserved.
