Yes, they've been known to use discrete freqs that aren't usually on the standard lists, and they have their own ALE setup on 2 different nets - one used as a Secure Internet protocol, the other Non Secure. I don't know whether they've ever used COTHEN but I sorta doubt it, given they have their own much more massive set of freqs to choose from. The Worldwide Utility News server (which is linked on our Utility Monitoring wiki) is the single best place to find freqs like this. 73s Mike
