ANALOG VS. IBOC: KSD 93.7
Frequency/Station Before

93.3 KNSX
Steelville, MO Semi-local
signal in Stereo Interference
to Stereo pilot*
93.5 MHz KRMS-FM
Osage Beach, MO** Wiped
out by KSD’s IBOC sidebands
93.9 MHz Either
Lincoln, IL or
94.1 KPVR
* denotes when the antenna is pointed in a southerly
direction
** denotes occasional reception
In this case, two good
channels for distant stations are lost to the IBOC sidebands, while
interference to the Stereo pilot tones for KNSX and KPVR are strongest with the
antenna pointed directly at KSD’s transmitter site in
southern St. Louis County, MO; some interference was even indicated to KNSX’s stereo pilot when pointed directly at KNSX’s transmitter site in Franklin County, MO. As a
result, 93X loses a good chunk of coverage in southern
