I heard an announcement on their "Afternoon Praise Party" yesterday that stated they will be going silent for a month then will be returning to the FM band. I don't remember hearing any specific time frames or new frequency mentioned, however.
I suppose they could lease an a brodcaster's HD-2 channel to be simulcasted on a translator. They could be making a deal with KDEE-LP as well.
There's also a little known new CP for an FM at 89.9 in Buffalo Hill, CA that Diamond might be looking at. The Longley-Rice map puts the signal above 54 dbu over most of the market. It wouldn't be much of a usable signal epecially with 89.7 KLRS, but they could buy a translator in the area. As you know, Non-coms can have translators thousands of miles from their parent station.
