I will use Chicago stations for examples, as I live in that market.
OK I understand how WFLD (FOX) and WPWR (My) share a channel as they are both owned by the same company. I am assuming since the amount of bandwidth is the same, the only reason for sharing the two station is they can do things like force a "must carry," because otherwise, why not just use one license to cover the bandwidth.
The second thing I noticed is that station WWTO is a full power station (now licensed to Naperville) but shares with low power WLPD-CD. So this means that the station doesn't reach as far as it could right? So my question is as a licensed full power station but only broadcasting on low power, does it still have must carry right?
The reverse seems to be the case in Boston where the low power NBC station, WBTS-CD channel shares with the full power WGBX so it gets the benefit of full power coverage without have the license requirements? Something similar but not exact in Rockford where WIFR-LD the CBS station has it's own low power channel but has an agreement to use WREX's subchannel so it is in effect a full power coverage.
Lastly the main question is how these sharing agreements work. I am assuming (and I may be wrong) they are only valid for a certain number of years. Now suppose WXFT (virtual Channel 60) is a guest on WLS-TV's (virutal channel 7) rf channel 22. Now supposing after this channel sharing agreement ends, WLS does not want WXFT to share what happens to WXFT? Does it sit in limbo till it can find some other station willing to share it's frequency? Or what elsee.
Sorry the post is a bit long but I wondered how this worked and often how it plays out in the real world. Any additional information you think would be informative or relevant I'd be interested in hearing.
