Contacting the State EOC

Whenever the State EOC is fully activated, the State EOC station, KD8MTL, will be operational. This includes statewide drills and exercises, as well as incidents and emergencies.

The station may be activated to support local or District exercises by arrangement with the station manager.

If an actual emergency or incident requires support from the SEOC station and the SEOC has not been activated by the State Police, notify the SEC of the need, ideally via E-Team notification. If the SEOC has been fully activated, the Station Manager and SEC will be notified by the Michigan State Police.

HF Operation

Unless arranged otherwise, the SEOC will monitor 3.932 MHz LSB and 3.563 MHz CW when operational. Other modes are possible by prearrangement. The station is capable of simultaneous operation on these two modes.

When the F2 Critical Frequency (F0) rises above 8 MHz, 7.232 MHz and 7.063 MHz will be used. If the critical frequency falls below 3.5 MHz, 1.932 MHz and 1.812 MHz will be used.

It should be noted that marginal F0 values (between 3.5 and 4 or between 7 and 8) or high Kp values may preclude the use of HF phone. Local EOCs should endeavor to have CW operators available. If the county EOC is not HF-capable, the EC should arrange to have a local strong HF station relay.

In times of adverse conditions, HF digital modes such as Olivia can be effective. At the current time, the SEOC station cannot use these modes without preplanning. It is expected this situation will be rectified shortly.

VHF FM Operation

The station at the State EOC is capable of monitoring local repeaters including the CMEN and IRA link systems. There are both IRLP and Echolink nodes nearby, but neither are reliably available. VHF operations must be planned in advance, although the station will typically monitor any repeater that may make sense for the event.

CMEN frequencies are available here and a coverage map here. The IRA coverage map which includes frequencies and tones is available here.

When available, the IRLP node is 7930 (N8HEE). Possible echolink nodes are 289654 (N8HEE) and 114032 (W8MSU).

VHF Packet Operation

The SEOC may be reached at [email protected] on the statewide packet system. When active, the station monitors channel 911 on the CONVerse bridge or the channel of the affected county.

Liaison with the Military Affiliate Radio Service is generally through VHF packet. ECs should consider developing relationships with local MARS members as potential alternate circuits.

MPSCS Operation

As a general rule, the MPSCS (800 MHz) system is not used. However, if necessary because other circuits are not available, or if desired for a test, arrangements can be made.


When the State EOC is fully activated for a statewide exercise or incident, the station will maintain a situation report in E-Team. When the station is activated for an amateur radio only exercise, E-Team is generally not available.

The SEC and backup can receive notification via E-Team, so a directed message to them from E-Team can be effective.


There are two telephones at the station operating positions:

  • 517-324-2381
  • 517-336-3984
Each EOC should have these numbers available for reference.
