[b]I was curious how much bandwidth is wasted by the simulcasting of the weather radar on several of our local affiliates
Here is an email conversation I recently had with the chief engineer from WFAA recently. As a courtesy to him I have deleted his name and email address.
Thanks for the kind words. We are working with vendors to develop compression technologies that will minimize the pixilation you see during high motion content. Keep watching.

FWIW, I notice during Monday Night Football and other HD broadcasts that there is a great deal of pixilation during the show. The wife constantly asks "Why do we have to deal with this?" I reply with "It's HDTV!!" I am receiving your ATSC signal with a strength of 90+ here in Cumby TX., Hopkins Co. at all times with a standard antenna at 28 feet. Thanks you for what you are doing for us(SkyWarn) and the rest of the ATSC capable viewers in the market. I work in the cable/satellite industry and I can safely say that the Plano and McKinney area is 80% converted to digital TV. We install attic antennas EVERYDAY!!!

P.S. If you have an e-mail address for the powers that be involved with that purchase, I can provide them a good reason to make the investment. The president of the American Radio Relay League which represents ALL of amateur radio in the entire country resides in Dallas. We can arrange a proposal that will blow their socks off.
$150k is not a lot of money to a company the size of Belo. Maybe the future will come before next spring. Your radar helps us save lives!!

Brian, our goal is to provide full time radar on 8.3 at some point in the future. Last week we were evaluating some new encoder technology that will allow WFAA to provide one high quality HD signal and two good quality SD signals all in our 19.39Mb stream. The new equipment is not cheap at $150k. Be patient with us. We are going to instruct our weather personnel to put the radar into the live window in 8.2 during major rain events, hopefully this will help you during severe weather.

This service is BY FAR NOT a waste of bandwidth. This precious service is the first REALTIME radar Skywarn has ever had access to. Before, we had the internet with a 3 to 5 minute delay. 3 to 5 minutes could be difference between early warning and no warning at all. I am a BIG HDTV fan. I have had HDTV since 9/9/01. Yeah the Sunday before. I remember that being one of the first things I saw on my new Mitsubishi/DTC100.
The 8VSB technology will undergo some major improvments in the near future. Channel 11 almost has it right but even then I saw an excessive amount of pixilation during the steelers game sunday with a 90% signal.

Mid grade RS antenna @ 28 FT with CM amplifier
I get >80% signal on all DT streams with the exception of KDFI which is around 50% here. I live in Hopkins county on the BIG hill between Greenville and Sulphur Springs.
