How many radios and what are their roles at each RFF?

4 total: 1-Guard, 1-VHF working, 1-DSC, 1-UHF Data

5 total: 1-Guard, 2-VHF, 1-DSC, 1-UHF Data

6 total: 1-Guard, 2-VHF working, 1-DSC, 1-UHF voice, 1-UHF Data

The question is about ensuring emergency, routine, and data/mission communications are covered at each RFF by having dedicated roles for each radio. The best setup gives six radios: one Guard, two VHF working, one DSC, one UHF voice, and one UHF Data.

Why this fit works: the Guard radio stays on the distress/priority channel so emergencies are always heard, regardless of traffic. A separate working VHF set handles normal voice communications without tying up the guard channel. A DSC-capable radio is essential for rapid digital calls and distress signaling, which can be more reliable under busy voice conditions. An additional UHF voice channel provides the military line-of-sight communications you may need, and a UHF Data channel handles automated or data transmissions required for tactical or status updates. Together, these cover emergency, routine, voice, and data needs in a clear, organized way.

The other options miss important pieces (like DSC or the data-capable UHF, or they add unnecessary redundancy) and therefore don’t provide the complete, appropriate mix for each RFF.
