I was listening to 154.800, it went quiet mid January sometime. I have (i believe) the OKWIN programmed as well but it's totally silent.
For what its worth, I heard them on 154.800 on a Uniden 355N while mobile a few days ago...
Have you checked for a PL tone change?
It's a bct15x. See my post below though. Does the basic models not rely on pl tones? I'm now confused
