Courtesy of longtime contributor Steven Green, this goes way back to just about the beginning of the Imus in the Morning program on WNBC.
Gary Bridges was one of a large staff of known personalities, some of whom listeners had grown up with. Personalities such as Don Pardo (the voice of many of WNBC radio and television's promotions), Soupy Sales, who had been around in the 1950s and on television, Imus, who by this time was already an institution and the whole WNBC news department.
Here's PART 2 in our series of AM-Stereo airchecks. WNBC used the Khan-Hazeltine AM Stereo system and while the transmitting plant itself was finely tuned and well-processed by NBC's top-notch engineers, heard on a (then) modern, wideband AM Stereo receiver, this sounds BETTER than modern processed FM stations!
