	Many metro areas that operate large UHF (450-470 MHz) and UHF-T (470-512 MHz) public safety systems have infrastructure in place for the UCALL/UTAC interoperability channels. Many, including Los Angeles, Boston, New York and Chicago, have their own regional/metro UHF interoperability systems as well - eg. BAPERN in Boston, NYMAC in New York City, etc. The UHF MED channels are used for regular day-to-day dispatch operations in some areas. In other areas, they are used for interoperability purposes, medevac communications to hospitals, or similar purposes. Nearly all communications on the MED channels is through repeaters. CTCSS tones vary depending on local needs and band plans. The 6.25 kHz MED channels are rarely used. MED-9, MED-10 and MED-1 through MED-8 are the most commonly used channels. MED-12, MED-22, MED-32, MED-42, MED-52, MED-62, MED-72, MED-82, MED-92 and MED-102 are used in some areas.
