Dir sirs.
This is an open letter to the Barbados Advocate, and others. This may be distributed and/or reprinted by anyone who receives it. I do hope and expect that the errors and corrections noted below will appear in the Advocate.
On page 14 of the Barbados Advocate, dated 2008.05.14 an article penned by one Kerrie Bynoe was titled “Digital Divide – saying goodbye to analogue TV”.
- The definition of “Analogue” is “Something that bears an analogy to something else.” The correct word in this context is “Analog”, which means “Of, relating to, or being a device in which data are represented by continuously variable, measurable, physical quantities, such as length, width, voltage, or pressure.”
- The author of the article mis-represents the transition which is occurring in the US (and 33 other countries), and has already occurred in six others. Specifically, the transition to “digital-only” transmission is really moving to High Definition TV (HDTV) (720i, 720p, 1080i, 1080p) from Standard Definition TV (480i, 520i).
- The author then suggests (“Are Barbadians Ready?) that the CBC has already made the transition. This is absolutely and completely false. While the CBC has migrated their MultiChoice service to use digital transmission (within the MMDS band in the 2.5 GHz range), they are *not* in any way prepared for HDTV service delivery, and the systemdeployed here is *not* able to handle HDTV signals. To tell the people of Barbados that they are ahead of the curve, when in fact they haven’t even started climbing the slope, is at best inappropriate.

On page 9 of the Barbados Advocate, dated 2008.05.13 an article penned by one Kerrie Bynoe was titled “A Copper market in Barbados”.
- It is stated that “According to electrician Jason Farley, copper is ideal for wiring because it does not lose energy when the electricity passes through it.” This is completely false. There is *no* metal which conducts electricity without loss (read: resistance) at ambient temperatures. Those materials which do are known as super-conductors, but these must be cooled to only a few degrees above absolute zero (0 degrees Kelvin, or -273.15 degrees Celsius). In fact, the search for a room-temperature super-conductor has been one of the holy grail goals of the material sciences for just short of 100 years.

One might hope that the esteemed and trusted Forth Estate in Barbados would spend the small amount of time required to check and verify technical facts for their printed articles.
Thank you for your time and attention.
