What Is Mixed-Mode Radio?
Mixed-mode radio explained
Mixed-mode radio refers to a radio system — or a radio channel — that supports both analogue FM and digital communications simultaneously. It is the migration technology that allows organisations to move from analogue to digital radio without replacing all their equipment at once.
How mixed-mode works
A mixed-mode capable radio automatically detects whether an incoming signal is analogue or digital and switches its receive mode accordingly. This means a digital radio operating in mixed-mode can hear transmissions from analogue radios on the same channel — and vice versa, if the analogue radio is compatible.
Why mixed-mode matters for radio upgrades
Most organisations upgrading from analogue to digital do so in stages — replacing radios department by department, site by site, or as older equipment reaches end of life. Mixed-mode operation allows new digital radios and legacy analogue radios to share the same channel and communicate with each other throughout the transition, preventing the network from fragmenting into separate groups that cannot talk to each other.
Mixed-mode limitations
When a digital radio is receiving an analogue transmission in mixed-mode, it cannot apply digital audio processing or use digital features like encryption or GPS. The communication works, but at analogue quality. Full digital benefits only come when the entire fleet has migrated to digital.
