That was my first thought too A2, but upon further reflection it occurs to me that VORs have a significantly higher radiated output than comm transmitters used to broadcast ATIS. Possibly a factor in reception range also? One could also listen to KSFO ATIS on the Point Reyes VOR (*H class VORTAC, elevation 1340') too if I recall.
Attached is the header from one KSFO Jepp chart and the A/FD. These same four frequencies are also on the panel of the San Francisco Sectional and TAC charts.
No doubt one VHF is arrival and the other is departure. Presumably, 115.8, the SFO VOR being on the center of the airport, would be departure ATIS, and PYE VOR, being several miles north and on a hill, would be arrival ATIS.
