JHS-770S/780D VHF Radiotelephone
JRC introduced in 2007 a new VHF product, It’s the JHS-770 series VHF, replacing the long running JHS-32 model. It comes with several new features. Available as semi-duplex or full duplex, the JHS-770 has a separate transceiver and controller allowing a more flexible installation approach in confined spaces. Built in Class A and Ch 70 watch keeping is standard as is ATIS (for European Inland Waterways) and a direct calling function by way of the AIS information. Other features include a high visibility display and recording function for the last 120 seconds of talking. Clearly noticeable will be the design philosophy of aesthetics and MMI as already seen in the NAVTEX NCR-333 and the new echo sounder which is JRC’s second new product.

Bearing, range and MMSIinformation of target vessels are sorted from the shortest range upwards. You can now easily select the vessel you wish to get in contact with, and send a DSC message immediately.
