Doesn't matter what the contours of KCIV are, if they have listeners that are being interfered with by a new, and especially secondary station, the onus is on the new station to resolve the interference.
Why is 99.7 bleeding over into 99.9 at all? Time for a new transmitter already?
I think it is time for KKDJ to move off the 99.7 frequency. I'm driving south on 99 near Olive, and KKDJ is not listenable! This is just a waste! WHY HAVE IT???
