Narrative:

125.35 is cle TRACON satellite frequency. As I was working this position I had 3 releases off of satellite airports all at about the same time. As they all tagged up on my scope, the aircraft were trying to contact me on our satellite frequency, 125.35. The frequency was out. No main or back up would work. The controller in charge was notified and I went to a back up miscellaneous frequency.
