So, stupid question: why couldn't 560 be diplexed with the KGO site by the Dumbarton, even if the station had to go nondirectional at a lower power? The 810 transmitter plant is there, it's co-owned, the towers are in place and probably decently maintained (understanding that This Is Cumulus...), wouldn't that be the path of least resistance if they really wanted to keep 560 alive? What am I missing?
Questions to ask:
1) How much would diplexing cost?
2) How long would it take to recover that cost?
3) What amount and kind of resources would one have to keep going during the amount of time it would take to recover the cost? In other words, how long could one hold out before the investment paid off?
I think there are very few entities that could provide a viable answer to all three questions. I don’t think Cumulus is one of those entities.
