Listen for yourselfs. Sample "A" has slighly brighter sound, but more noticable distortion in the bass line.
Samples B and Sample C sound the same as FM.
Which brings me the point of simulcasting? What's the point?
The FM antenna used was an omni-directional set of crossed dipoles. Reception of FM stations from New York City and Conneticut using this antenna on a normal FM receiver is quite acceptable. Even the Receptor radio did well hearing analog signals on this antenna. However, only four stations showed any signs of a digital signal. All were from Conneticut and none from New York City. Two of the stations indicated presence of a digital signal but the radio would not switch out of the analog mode. One has a good signal here and the other is fairly strong. On the other two signals the radio switched in to the digital mode. These stations were very strong.
Oh boy, reception troubles with outdoor antenna!
There are no AM samples. This location is @35 miles from New York City on Long Island. While signals from the NYC AM stations are decent here, of those that were running IBOC there were none strong enough for the radio to switch to the digital mode. In fact, the sensitivity of the radio was so poor we were lucky to hear any stations in the analog mode. Relocating the supplied loop antenna did not solve the problem.
Whoa!
