The Icom IC-R30 does have features that support the display of unit IDs, but this capability is limited to certain digital modes. Here's a breakdown of how it handles unit IDs in the supported digital modes:
D-STAR: The IC-R30 can display the callsign and unit ID of transmitting stations in D-STAR mode. This is part of the D-STAR protocol, which includes metadata such as callsigns and unit IDs.
P25: In P25 mode, the IC-R30 can display the unit ID (Radio ID) of the transmitting radio. P25 is commonly used in public safety and professional communications, and the unit ID feature is integral to the protocol.
NXDN: The IC-R30 can also display unit IDs in NXDN mode, which is used in commercial and industrial applications.
While the IC-R30 can display unit IDs in these digital modes, it does not have a specific alert feature solely for unit IDs. It will show the unit ID on the display when receiving a transmission from a radio that includes this information in the supported digital modes.
For users who need more advanced alerting and tracking capabilities based on unit IDs, specialized digital scanners or software-defined radios (SDRs) with trunking capabilities might be more suitable. These devices can provide more detailed control and alert options for monitoring specific unit IDs within trunked radio systems.
