The Quantum GX3500S is an ITU Class D marine transceiver that has been approved by Transport Canada for commercial use on specific vessels. A separate Channel 70 receiver allows DSC calls to be received even when listening to traffic on Marine VHF channels. Designed to take the day in and day out punishment the marine environment can dish out. The GX3500S can take submersions or more likely direct water from waves crashing over the bow. Oversized knobs allows 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 the boldly display channel names, DSC call information and even GPS position with Speed Over Ground and Course Over Ground. The standard hand microphone has a built in speaker and uses Noise canceling technology called ClearVoice for unsurpassed communications even in the noisiest environments. This microphone also has the capability to directly switch between channels 16 and 9, change channels with the large UP/Down keys and can be removed for storage.

The QUANTUM GX3500S has a 30 W Loud Hailer with 4 programmed Fog signals, Bells and Whistles even Listen back! Simply purchase one or two RAM+ mics and be able to control these functions remotely. The Quantum is so advanced it also allows you to control the fog horn frequency! When in the PA or Fog modes the receiving the last selected VHF channel or DSC calls is not problem.

There is no need for a dedicated Intercom system when you have the QUANTUM GX3500S and RAM+ microphones! Want to talk from the GX3500S to one RAM+ or both simultaneously or from a RAM+ to RAM+ or RAM+ and GX3500S you can! STANDARD HORIZON has even built in a Calling feature that allows you to individual alert the GX3500S or RAM+ from the station that is being used. Clearly the GX3500S is the next step in communicating on your vessel.

STANDARD HORIZON has pioneered the capability to poll (request and send) the GPS location of another vessel and show the position of that vessel on the VHF's display. Standard Horizon has taken this feature one step further, if any Standard Horizon GPS is connected to the GX3500S the polled position of the vessel is shown on the display of the GPS chart plotter making it easy to navigate to the location of the polled vessel. This is a great feature for anyone wanting to know the position of another vessel.

The GX3500S has the capability of being connected to TWO, Enhanced full-function, remote microphones (RAM+ Mic). This advance remote operates as a full second station to the GX3500S at the fly bridge, cockpit, tower or location of your choice. The submersible RAM+ has a huge channel display, speaker microphone that allows the user to remotely control all VHF radio functions including PA and Hailer functions, Digital Selective Calling functions and can show channel names and repeat GPS information.

Because the GX3500S is built better, it's backed better. If the STANDARD HORIZON GX3500S fails for any reason (including water damage) during normal use for the first 3 years of ownership, STANDARD HORIZON will repair or replace it free, without hassles or charges. If it fails for anytime thereafter in normal use, for as long as the original purchaser owns the radio, STANDARD Horizon's Lifetime Flat Rate and Customer Loyalty Service Programs will cover it.
