Simrad takes the latest step in the march towards GMDSS-friendly VHF communications

Simrad’s latest VHFs – the RD86/87 and the RS86/87 – are targeted at pretty much everyone using VHF: all sizes of yacht, powerboats, fishing boats and workboats.

The RD/RS86 models are operated with handset or a fist mike featuring a built-in speaker and channel changer buttons, to help listening to weak transmissions and escape noise on deck or below. Its souped-up sister, the RD/RS87, has an all-singing, all-dancing handset that allows complete dVHF communications through a new low-noise system that clears up reception.

The RS models are fully capable of full function dual station or relay operation through the handset. This means a station mounted at the helm can be used to communicate with another dual station, in the navigation station for example, making crew communication considerably more effective.

The main differences with the RS range are that they have a built-in scrambler to allow secure communications when used with DSC ship-to-ship calls. There is also an optional iDSC output function which can, when linked with the Simrad 42 or 52 series VHFs, allowing any DSC message received to transfer directly to the screen. The recipient can then acknowledge – turning off the alarm – and send a working frequency.

The Simrad sprung cover still protects the GMDSS activating button on all the dVHF units.
