Why cant WFLA 970 stay on the air?

S

For a week or so now the 970 transmitter cuts off over and over again. It is happening during their most productive day parts.... Getting really annoying as a listener.
 
Hey, I got an idea, maybe Clear Channel can take one of their underperforming FM properties like Mix and turn it into a simulcast of WFLA -- nah, nevermind, bad idea...
 
I've noticed that their transmitter is tripping off from time to time. It may be an antenna bandwidth problem.
Their IBOC "hash" has always been very annoying to me. This high level of hiss may indicate that their antenna bandwidth isn't broad and flat enough to pass the IBOC signal cleanly.
 
I know that they had some trouble with one sideband and the corresponding IBOC sideband was weaker, so the signal was not symetric. I saw a spectrum analyser shot of their signal that showed that. That is a fairly complicated site co located with 1250, a combiner separate phasers and 5 towers. Arent they using Harris DX25's?

Non symetrical sidebands would explain the IBOC hash that I hear. It's much worse in their nulls.
 
Man, if you guys ever learn to speak English, you'll be dangerous! j/k ;)

Seriously, on a non-technical aspect, CC has a bar minimum of engineers. Could it be that they are just slipping a bit on the being able to properly maintain all those signals?

By the way, that is not a knock on those guys. They're excellent professionals, but keeping that cluster going is an awful lot of work.
