You’re looking at $15-20k in user fees for the estimated life of the radios, then sticker shock if they suddenly require upgrades, or worse…arbitrarily determine to de-platform your agency.
True about upgrades, but major functional upgrades (like LLA) are unlikely to be needed by this time.
MARCS cannot arbitrarily “de-platform” a user unless it’s specifically stated in the user agreement that they can, and that’s usually only in cases of serious malfeasance or long term non-payment of user fees (and even that’s unlikely to get someone kicked off; as of 2023, there were quite a few agencies seriously in arrears who hadn’t been kicked off).
Being on MARCS for most small agencies is still cheaper than buying your own system. 25 radios at $5/month is $15,000 over 10 years, and a
good quality repeater is at least that plus the cost of installation and annual maintenance. With MARCS you have better coverage along with interoperability, and the state handles all the heavy lifting.
Buying and installing your own system gets financially feasible only for large municipalities, or when the county bands together to purchase and install the system to spread out the cost.
