As is the
case with WIL, this illustrates the fact that WMVN’s
IBOC operation wipes out 600 kHz of spectrum space. By contrast, analog takes
up less than 200 kHz of space, and produces superior audio quality over IBOC.
The audio quality of WMVN (known as “Movin’ 101.1”) was
already CD-quality before they made the illogical step of switching to a
spectrally inefficient technology that has no technical integrity. In the case
of WMVN, there is a semi-local station on 100.7 MHz. Pointing the antenna
toward WMVN’s transmitter site, signals on 100.7 MHz,
dominated by KFNS-FM Troy, MO, are practically unlistenable.
