Anomalous
Spectrum Scans
WFLL 1400 Fort Lauderdale
The sidebands are different sounding than strong IBOC stations,
but have obvious similarities.
A brief .WAV file recording (195kB) of the WFLL
broadcast
and adjacent sidebands presents the sounds in the sequence: 1400
- 1390 - 1400 - 1410
- 1400
Later monitoring of WFLL when the on channel audio was again
working
properly found the strange sideband noises no longer present.
These sidebands sounded similar to sounds heard in the aftermath of a
hurricane and were likely the result of transmitter malfunction,
unrelated to IBOC.
