To further what Hazmat34 has already stated. MARC frequencies are valuable when an incident requires multiple agencies (fire departments, police departments, flight for life, ALS ambulances, highway department) to respond that normally don't work together.2 trucks long truck 2 cars I94 near K 154.6550 . raido problems "switch to the marks channel" ?
Your guess is as good as mine. I am assuming he means the crash on Thursday that closed I94 near CTH G. It was a mess.2 trucks long truck 2 cars I94 near K?
What does that mean?
Not all of them, in fact I'd venture to guess that only some could actually be controlled by DTMF. If there is a 24 hour POC and the sponsoring agency can control it by wireline, then it does not require remote (DTMF) control.The MARC repeaters are activated by DTMF.
