SIMRAD RS20 VHF Radio

 

Part # 000-13545-001

 

 

Simrad RS20 Class D DSC VHF Radio is an entry level VHF radio with NMEA2000 connectivity for GPS position, backlight control and night mode grouping with Simrad MFD's. Radio has NMEA2000 connectivity for advanced functionality like backlight grouping when connected to Simrad MFD's. NMEA0183 connectivity and receive GPS data from a compatible GPS unit. Output DSC (for DSC call), DSE (for enhanced position when doing latitude/longitude request and buddy track). Radio has a new front mountable mechanical design for easy installation and is low profile to align with style of Simrad MFD's. Full inbuilt country specific channel banks, no requirement for LC programming or cloning.
 
Other features included are Start-Up Wizard; giving region & country selection, enter MMSI, call sign, GPS source selection and time offset. Improved SCAN features; All Scan, All Channels + 16, My Channels, and My Channels + 16. Favorite's Shortcut; customizable favorite functions of defaults, contrast, sensitivity and VHF info. Channel Name; my channels, set channels as favorite channels, enter favorite channel mode by long pressing channel dial and only favorite channels will be included in channel scrolling. Track up to 5 buddies! Track buddy is a feature that automatically requests the position of another VHF radio. Simply enter the MMSI of the VHF into your contact list, then start tracking! Polls your contacts for their latitude/longitude position automatically. Can be set to 1, 5, 15, 30 or 60 minute intervals. Displays the position on a compatible chart plotter, great for keeping track of friends, family or vessels you need to know the position of.
