What is the radio frequency used for Region 11 ambulance to hospital communication?

• A. MERCI 340 (155.340 MHz)
• B. STARCOM21 (700/800 MHz)
• C. MED CHANNEL 123 (452.000 MHz)
• D. REGION 11 EMS Frequency 138.000 MHz

Answer: (A)

Region 11 uses the MERCI radio network for ambulance-to-hospital communications, specifically on 155.340 MHz (MERCI 340). This channel is designated for direct link between EMS crews and hospital ED staff to relay patient information, receive orders, and coordinate arrival. The other systems serve different purposes: STARCOM21 on the 700/800 MHz bands is the statewide interagency public-safety system, not the EMS hospital-to-field channel; the medical channel on 452.000 MHz is a separate medical frequency not the Region 11 ambulance-to-hospital channel; and the local Region 11 EMS frequency of 138.000 MHz is a different EMS channel, not the official ambulance-to-hospital line.
