WBZ!

Mark Durenberger no doubt knows more about this than I do, but back in the 
60s-70s when there was talk of allowing the I-A clears to go to 750 kW, 
Westinghouse acknowledged that there was no way that KDKA and WBZ could 
co-exist with 750 kW each at night. They were prepared even then to keep 
KDKA at 50 kW and allow WBZ to get the big juice (with a proposal to put 
the transmitter in Provincetown, at the tip of Cape Cod!), accepting 
whatever interference was received to KDKA.

The present situation is eerily similar.
