Our county repurposed former schools, parks and rec and public works high band VHF 16- channel ICOM F3S radios by removing the Smart-Trunk boards and reprogramming them to the MURS channels for issue to CERT, Neighborhood Watch and Medical Reserve Corps.
Any of the older analog VHF high band 154-160 Mhz radios by GE, Motorola, Vertex-Standard, E.F. Johnson or Bendix-King can be modified by any 2-way radio shop. The Bendix-King is frequency agile and be programmed directly from the keypad. Others require a computer interface cable and software.
The various ICOM F3 radios were widely used for range control by the Army and sold off as surplus in the 1990s. Mine is a 256 channel version which has 2-meter ham, MURS, VHF Marine, Ground SAR, EMS and Fire Ground talk around freqs all in one unit. You can program wide or narrow band FM and power output by channel and also program channels like the NOAA weather or EMS dispatch to receive only.
With the older radio you can expect to need to rebuild or replace battery packs and antennas in addition to reprogramming, so they are not "plug and play. But after investing about $100 in each obsolete radio salvaged from the dumpster at the County radio shop after the P25 digital conversion you can have " All VHF-Analog" in one unit. We repurposed several hundred of them and are still using them 20 years later.
