WASHINGTON, DC — Technical experts will discuss the impact of an in-band -on-channel (IBOC) proposal recently submitted by radio broadcasters to the FCC at The NAB Radio Show. Geoffrey Mendenhall, vice president of transmission research & technology at Harris Broadcast Systems, will moderate the panel discussion featuring executives from Continental Electronics, Broadcast Electronics, Nautel, Greater Media and NPR.
The proposal would allow FM broadcasters to increase power in the digital portion of their IBOC signals by up to 10 decibels (dB), to increase their digital coverage area and to improve reception by portable HD Radio receivers which are soon to be on the market. Attendees will learn how to design new facilities to operate at these higher power levels, and will also examine the issues surrounding the upgrading of existing facilities. Session participants include:
