John Kean has joined consulting engineering firm Cavell, Mertz & Associates.
He was most recently senior technologist at NPR Labs for 11 years.
Kean has been involved in various broadcast projects, including digital radio, RF signal propagation analysis and signal mapping.
Kean is a member of the National Radio Systems Committee, which sets guidelines and standards for broadcast technologies. For the NRSC, he studied power-saving AM Modulation-Dependent Carrier Level compatibility with HD Radio and the performance of Single-Sideband FM Stereo and its compatibility with present-day FM receivers. He also recently developed and supervised a study for the Consumer Electronics Association on loudness range preferences of listeners.
In an earlier stint at NPR Kean focused on technology projects for the network and FCC regulatory activities on behalf of public radio. He then joined engineering consulting firms Jules Cohen & Associates and Moffet, Larson and Johnson, where he focused on the fields of PCS systems, analog and digital television and radio facilities, FCC regulations, microwave and satellite systems, and mobile cellular networks. He returned to NPR in 2004 to help establish NPR Labs.
John also holds a U.S. patent for a technical algorithm for determining the signal coverage capability of In-Band On-Channel broadcasting, which we now call by its brand name — HD Radio.
