I see the "New" Ohio MARCS section... is this the radio system that will eventually replace the current Ohio MARCS system or will they be kept separate?
To amplify and clarify what Ron said...
MARCS-IP will replace the current system, which will then be decommissioned and the 800 MHz frequencies moved over to the new system. The use of 700 MHz frequencies on MARCS-IP is a means not only of getting the system on the air but also a means to increase site capacity once the 800 MHz frequencies are repurposed.
Existing MARCS radios are already mostly capable of P25 operation and won't require flashing, but will need to be reprogrammed to add the MARCS-IP system. Nearly all are already capable of 700 MHz.
Talkgroups will not remain the same but will be all new.
