On the LiveATC page for KPUB, there is a dedicated feed for Tower #2, 123.675. I've been listening to it lately and haven't heard anything at all on that frequency. Does anyone know if KPUB currently uses 123.675, and if so, for what purpose? It's not listed in any charts I could find, and it's apparently not patched to other frequencies (assuming the Feed Radio for 123.675 is up and running properly). I don't live anywhere near that airport, so I have no way of monitoring the situation directly so to speak. Hopefully someone down south can shed some light on this...
