Las Vegas - At the 2010 NAB Show Geoff Mendenhall, vice president, transmission research and technology for Harris Broadcast Communications, was named the recipient of the newly created "NAB Best Paper Award" at the convention.

Mendenhall's paper, titled "Extending Your HD Radio Footprint," was selected from approximately 50 papers presented at the NAB Broadcast Engineering Conference on the topics of radio and DTV broadcast technology. The educational paper was targeted to help radio station engineers seeking ways to improve HD Radio signal coverage. Mendenhall discussed recent changes to the FCC rules and regulations and also provided a specific blueprint that radio stations can follow to plan HD Radio coverage improvements.

The paper was considered unique to other presentations at the show, focusing on elements that have not been widely covered in industry documents. Specifically, the paper covered:

  • The pros and cons of space combining vs. common amplification
  • How to correctly size a transmitter plant to accommodate elevated HD Radio sidebands
  • Overcoming transmitter linearity challenges
  • How high-level combining of FM and digital transmitters can work with a filterplexer
  • Using unequal HD Radio sidebands to prevent interference with adjacent channels
  • New opportunities to improve HD Radio coverage through the use of digital + analog gap fillers and translators

    The paper is included in the proceedings of the NAB Broadcast Engineering Conference available from the NAB bookstore.
