Ty... The meaty parts are behind Fybush's paywall, and while he takes a mean picture of a broadcast tower, I'm pretty meh about paying for his newsletter. Seeing the speculation come from Fybush lends a little bit of credence to it, but still, though, to me that doesn't make sense, considering WFMZ still has KJWP and a low-power transmitter in Philadelphia on RF 45 plus whatever additional spectrum they bought.
WFMZ, WBPH, and WLVT are all on WFMZ's tower at South Mountain already, so, yeah, okay, sure. Contours and footprint probably would remain the same. But are there any examples of eight virtual channels (69's 4, 39's 2, and 60's 2) sharing one physical channel anywhere else? Wouldn't there be bandwidth limitations? I don't know enough about this newfangled "H Dee" technology to really know, so someone please educate me, but it doesn't seem like it would work all that well.
