Various articles and statements about the C-QUAM AM stereo system over the years have said that the range of the signal is lower than mono AM (for the same transmitter power level).
AFAIK, the signal strength (at a given distance) of the L+R portion of the C-QUAM signal is the same as a mono AM signal.
(KCJJ 1630 AM stereo [did the matrix quad broadcasts encoded for Dolby Pro-Logic 2 music decoding in 2011] switched back to mono in 2012, they stated that their signal coverage was less w/AM stereo)
Does C-QUAM reduce the coverage of an AM station?
