Trooper Helicopters
Maryland State Police

MSP helicopters are controlled by SysCom in Baltimore (44.74 MHz).  SysCom (Systems Communications Center) manages dispatch and medical radio communications for Maryland State Police helicopters throughout the state.  The helicopters are equipped with Wulfsburg Flexcomm radios.  These radios cover 30-512 MHz and are commonly used on medevac helicopters.  Troopers use the radio frequencies of the local police and fire departments responsible for the incidents they work.  Frequencies in the 30-512 MHz range are locally patched to 800 MHz trunked systems where applicable in Maryland for the Troopers' use.  In rural areas of Maryland, EMS consultations with hospitals are patched by SysCom using 47.66 MHz (or 47.50 MHz as an alternate).  The Troopers also may do hospital consultations via EMRC on the "Med" channels.  SysCom will send the Troopers out of state for mutual aid when requested and available.  SysCom also coordinates mutual aid helicopter assistance to Maryland.

In Montgomery County the Trooper can generally be heard on Fire/Rescue channels 1, 2, 3, 5, as well as Police channels 1-5, but may be heard on other channels and frequencies depending upon the situation. In the Montgomery County area mutual aid may be received from the U.S. Park Police (Eagle), Washington Hospital Center (MedSTAR), or INOVA Fairfax Hospital (AirCare).
