The RADAR group.

The RACES ARES Disaster Assistance Repeaters (RADAR) group was formed by a team of amateur radio operators dedicated to providing high quality repeater communications for amateurs involved in public service communications or responding to emergency or disaster situations. We are affiliated with Wayne County Emergency Management, Oakland County Office of Homeland Security, and the Michigan State Police 2nd District Emergency Management.

Using the FCC call sign WR8DAR the RADAR group currently operates 2 meter, 440, and 900 Mhz repeaters in various locations in southeast Michigan. We have plans to add a repeater on the 6 meter band as well. Our plans also include linking UHF repeaters for wide-area seamless coverage. Our members individually own all but one of our repeaters, and they have dedicated them to the organization for the benefit of all. 

No membership is required to use the RADAR repeaters so dues are not required. Donations for the maintenance and upgrade of the repeaters are appreciated.  Contact us at [email protected] for information.
