Considering the signal coverage overlap that has always existed ever since 1040 went on the air, this is a good idea.
Let's just hope they get the audio on both signals exactly in synch. I remember when Roberta Gale's talk show was simulcast on 94.3 and 94.5. If you were in an area where both signals were equally strong and had a less than perfect radio, you could hear an echo as your radio began to pick up both signals simultaneously, because the audio was not in synch on both stations.
Anyway, 1040 WCHR is truly a squeezed-in station which should have never gone on the air in the first place. Just like the old 1510 WRAN, their daytime signal is just too directional to have good coverage where it would count most (Trenton & Allentown), and as a result it is mostly wasted over rural areas. And then at night, the signal changes to a completely different directional pattern, so that most of the daytime listeners lose the signal at night, and most of the nighttime listeners lose the signal during the day.
