25 Watt VHF FM Marine Transceiver
Oversized alphanumeric LCD Knobs and Keys
Designed to take the day in and day out punishment in the harshest environments. The VM-3500E can take submersions or more likely direct water from waves crashing over the bow. Oversized knobs allow for easy adjusting of Volume, Squelch, channel changing and moving through radio and Digital Selective Calling functions.
The LCD is one of the largest in the industry with 4 lines of Alpha-Numeric characters that boldly display channel names, DSC call information and even GPS position with Speed Over Ground and Course Over Ground. Programmable scan, Dual Watch and Ch16 priority scan allows you to scan any number or combination of channels so you will not miss a call.
Capable of being connected to RAM + second station microphones
This advanced remote operates as a full second station to the VM-3500E at the fly bridge, cockpit, tower or location of your choice. The submersible RAM+ has a oversized display and keys that allow the user to remotely control all VHF functions including PA and FOG, Digital Selective Calling functions, show channel names and repeat GPS information.
Unique Intercom System
There is no need for a dedicated Intercom system when you have the VM-3500E and RAM+ microphones! Want to talk from the VM-3500E to one RAM+ or RAM+ and VM-3500E you can! VERTEX STANDARD has even built in a Calling feature that allows you to individually alert the VM-3500E or RAM+ from the station that is being used. Clearly the next step in communication on your vessel!
30W Loud Hailer with listen back and 4 fog horns, bells & whistles
The VM-3500E has a 30W loud hailer with 4 pre-programmed Fog signals; bells and whistles even listen back. For advanced users the VM-3500E allows you to select the fog horn frequency for true versatility. Most VHF,s with a PA do not allow monitoring VHF transmissions; this has been solved with the VM-3500E Simply tune to a channel before selecting the PA mode and when a VHF transmission is received you will hear the conversation. In addition, all the PA functions can be controlled by using the optional Enhanced RAM+ remote speaker mic.
