UM725
Fixed Mount Marine Radio
Uniden is the first to offer text messaging using marine VHF radio. You and your crew will enjoy the privacy of texting boat-to-boat, rather than broadcasting over your radio for all the boats in your area to hear. The UM725 marine radio comes packed with the latest features, including IPX8 submersible rating, NOAA Weather Channels, DSC Distress send and receive, and speaker microphone equipped.

NMEA0183 Input and Output
SEND/RECEIVE GPS & DCS INFORMATION
NMEA 0183 (version 4.10), a standard for data communication between marine instruments. NMEA sentences contain different sets of data related to your ship. When your radio receives another boat’s position data in a DSC call, the radio sends the position data to the chartplotter so you can see the location


NOAA WEATHER CHANNEL WATCH
WITH WEATHER ALERTS
The radio scans channels according to your radio settings, including Priority and Weather Alert watch, if set. If the radio detects a transmission, it stays on that channel; when the signal stops, the radio resumes scanning. When the radio receives a transmission, it pauses the scan and stays on the transmitting channel.
