Science Fiction Unit Callsigns
Create a radio identity with a consistent unit prefix, fixed-width numeric identifier and spoken call word. Keep locked identifiers distinct and compare compact alternatives. In the accompanying garden-cart race, an exact call makes a technician answer for an unearned delivery; a useful identifier cannot win her back a lost lap.
Enforce unit prefix, fixed-width number and spoken call word.
- Unit prefix
- Fixed-width identifier
- Call word
- Spoken number form
ARC, 042 and Lark are separate components. Different call words do not make a repeated numeric position valid.
