A paper from Triveni, “TV Broadcaster Connecting with the Mobile User,” presented by Richard Chernock at NAB2007 offers an easy way to implement a form of mobile DTV.

All 2-GHz broadcast equipment will be upgraded to digital technology and will be operating under a new band plan that keeps the same number of channels but reduces their width to 12 MHz.

When I started my RF Web site back in 1995, there were few with information on RF and TV broadcasting. Eight years later, almost any question about RF can be answered with a quick Google search.

This month I'll use two recent examples of DTV-to-analog interference to show how I analyzed the interference and determined some possible reasons how it could happen.

The FCC database used for FCC Bulletin OET-69 interference studies does not include TV stations' real antenna patterns.

At NAB2004, broadcast engineers were focusing on getting ready for the shutdown of analog TV.

This month, I'll look at some of the things to consider when deciding on a DTV channel, and also relay some information I received from readers about low VHF DTV.

This month I'll look back to address comments received on my November RF Technology column and look forward to TV broadcast RF issues I believe will be important in 2004.

The FCC is actively checking broadcast sites for compliance with FCC Rules §1.1310, RF radiation exposure limits.

At this year's NAB, the focus was not on debates about DTV standards or the transition, but discussions on how to make DTV transmission and reception work and improve DTV broadcast equipment.
