MIRO

The Mercer Island Radio Operators (MIRO) is the volunteer team that provides auxiliary technical and communications support for the City of Mercer Island and its Police and Fire Departments in the event of natural or man-made emergencies.

MIRO operates under the authority of the City of Mercer Island Department of Emergency Management and reports directly to the City’s Emergency Manager, Amanda Keverkamp at 206-275-7795 or amanda.keverkamp@mercergov.org.

MIRO is one of several Emergency Preparedness volunteer teams on Mercer Island, and not a “ham radio club.”

Meetings

Emergency Practice Net: Second Thursday of the month at 7:00 PM

The net is conducted on the MIRO VHF repeater frequency of 147.160 MHz positive offset tone 146.2 Hz. The check-ins are by assigned neighborhood region.  After announcements the net shifts to the UHF repeater 440.150 MHz positive offset tone 103.5 for a role call of those who have checked in on VHF.  The purpose is to practice shifting frequencies.

In the event of a repeater failure, the net will switch to the simplex frequency of 147.440 MHz.

Monthly Meeting: Third Thursday of the month at 7:00 PM

The MIRO meetings are typically held at Mercer Island Fire Station 91 but are temporarily moved to the LDS Church at 4001 Island Crest Way on the SW corner of Island Crest and SE 40th Street.

All MIRO members, prospective hams, and visitors are encouraged to attend.  The monthly MIRO Newsletter will specify meeting location and subject.
