Peak Broadcasting let two members of its on-air staff go Wednesday, according to reliable sources. Greg Williamson and Melissa Dawn Liebenthal were both let go by Peak from their jobs as utility players (both held down shifts on KXLT/107.9 Lite FM). Melissa has been with the company since way back since the Jacor days, while Williamson was on his second tour of duty with the cluster. Williamson also anchored morning traffic updates for the cluster – a job Tobin Jeffries will now step into. It is unclear how the rest of the KXLT broadcast day will shake out. The station went “all Christmas” on Friday as it does each year.
