Re: [IRCA] 1470 WWNN IBOC off, or something.

["W. Curt Deegan" <WWWR@xxxxxxxxxxxxx>]

Regarding 1470 WWNN Pompano Beach, and their appearance on 1480 when their
IBOC was off.  Upon further investigation I have determined that this was
indeed an artifact of their IBOC signal...sort of.

When WWNN turned off their IBOC I was able to hear the first harmonic from
740 WSBR Boca Raton.  Both stations are owned by the same company and at
the time I was listening they were both carrying the same program.  Later,
with WWNN IBOC still off and unique programming on the two stations, it was
apparent what I was hearing.

The Bad news is that for the last couple days I've found the IBOC to be 
back ON.
Whatever prompted it's silence has, alas, passed.

Again there are two noise makers in SE FL ... not counting Cuba.
