39.5000 MHz is the Statewide Lo Band for Interop. It is used for Emergency Management, Police, and was formerly used in Vidalia as the FD Tone Out freq. It is also the current MHP/LSP interop freq. As the Nationwide V-Call/V-Tac, and U-Call/U-Tac freqs are programmed into all the MHP Mobiles, MHP-LSP will then switch to the VHF Hi Freqs.
Lo Band will gradually be phased out in all areas of LA as the LATIE plan is implemented.
