Re: [IRCA] WHP 580 IBOC
Yes Patrick, WHP does use IBOC but only during the day when
the station is nondirectional. The program director told me
it would be very expensive to modify the night time
directional array for IBOC and I guess Clear Channel didn't
think it was worth the cost. If IBOC had become more popular
the modifications might have been done. I wonder if the
station pays less for an IBOC license since it isn't on all
the time.
In a number of AM stations IBOC is only on daytime. WHJJ-920 (Clear
Channel) and WDDZ-550 (Disney) didn't use IBOC at night. Both had too small
a bandwidth for night pattern. We tried it at night at WDDZ. The
distortion was so severe it wouldn't even decode in the transmitter building
or in the parking lot. Current WBZS-550 (Salem) will not be using IBOC at
all. FWIW, there was not one complaint about IBOC being gone on 550. I
suspect that if the WHJJ-920 IBOC fails it may not ever be repaired.
Probably won't be missed there, either. It's a talk station so sound
quality is less important.
For WDDZ to use IBOC at night they would have had to replace the towers and
most of the antenna tuning parts. Would have been a quarter million
dollars, according to an estimate.
