I believe that freq is part of the Niles Radio LTR system. I usually hear the Sedona Trolley on it.
Since its a trunked system there won't be any PL or DPL tones. You'll need a trunk tracker scanner capable of following an LTR system to track them accurately (although the freq doesn't appear to be that busy, so you could listen to White Tie and the Trolley without a trunker).
