WOW! There are so may knowledgeable users in this group. This makes me wonder, what are the REAL numbers for KRBE and they are low enough, would they be willing to do a format change. It would cost them almost nothing to run the True Oldies Channel, because I believe they (Cumulus Media) owns it. The have had good success with it in Chicago when they ran it on WLS-FM.
No idea what the numbers are now, but the last time there were any public numbers for KRBE, it was cuming well over a million. I suspect not much has changed, and I also suspect there is zero chance of a format change at 104.1.
