This didn't make sense at first, but now it's clear:
KLIF takes the ABC top of the hour news, to keep it from going to a competetor.
KLIF takes a couple of tenths from KRLD, maybe keeping KRLD from passing 820.
820 eliminates a conservative talk competetor, possibly picking up a couple of tenths.
Existing resources are leveraged across another outlet.
Building a strong station/brand is not a priority, nor is serving the community, but at least Cumulus still has another place to park pay-per-response and pay for play programming.
