Radio Amateur Civil Emergency Service
The IDHS Amateur Radio Disaster Communications ("Ham") Team supports auxiliary communications through the RACES program using amateur radio frequencies and any other means necessary. The Team also supports all other amateur emergency communications programs in the state of Indiana.
Military Auxiliary Radio System
IDHS-HT proudly partners with USAF-Military Auxiliary Radio System (M.A.R.S) for emergency communications interoperability. The Indiana Department of Homeland Security has been issued an Agency License to operate on military frequencies using specially trained amateur radio operators. Preparedness is practiced using both voice and digital communications.

Indiana State HF Test
Purpose of the State HF Test
The directed test conducted twice a year exercises the communications between the County EMAs and the state EOC over amateur radio frequencies. The designated radio operators are encouraged to use any or all of the announced frequencies and modes to test equipment and propagation. Counties checking in are encouraged to relay for other counties to assist and ensure participation in the state test. The use of HF voice and digital modes are highly encouraged.
Who may check in to the State HF Test
Any amateur station appropriately licensed by the FCC and designated by the county’s EMA director may check in representing that county. A single station represents each county on a given frequency and mode. The EMA director may designate any station to check in to any or all test frequencies and modes as he or she chooses. As part of the Test, counties are encouraged to conduct their own local Nets and to report the count of their check-ins as traffic for this Test. However, individual stations are NOT invited to check in for this test without prior authorization from the EMA director.
