The Jotron TR-810 VHF AM Multi Purpose Radio Offshore Version 83200OF is based on the Jotron TR-810 VHF AM Multi Purpose Radio that has been designed to be largely future-proof against possible requirements for the versatility of a ship-borne radio.

Basic qualities of the TR-810 VHF AM Multi Purpose Radio are that it is robust in construction yet still lightweight.

It is available in six configurations: Vehicle, Desktop, Man-Portable, Last Resort*, Sub Rack* and this one, the TR-810 VHF AM Multi Purpose Radio Offshore* Version (*available from Outdoorgb.com).

The operator’s control panel (OCP) is detachable from the compact base unit and communication between the two elements of the device is through a standard CAT-5 cable, the module design being what enables the versatility of its applications.
