Marine VHF Radio Replacement

Category: Electronics

Maintenance/Repair Details: Due to the failure of the Navman 5500i chart plotter to find and hold GPS satellites it has been necessary to bring the whole electronic side of navigation up to date. As such both the chart plotter and Navman 7100 radio, both at least 20 years old, have been removed.

Being that we now use a Navionics tablet based navigation system the only new item required was a new VHF radio with built-in GPS positioning to give us the most up to date distress positioning system. 

Completely recovered the top of the helm dash to complement the new streamline look to the helm. 

21 July 2022 - Installed a new whip antenna on wheelhouse roof, removed old fibreglass antenna and made good the area.

Parts and/or Items Used: Cobra VHF FF77 GPS Marine Radio. Supergain Target 530mm Antenna.

Old electronics removed with the new radio in position. Replacement and repositioning of the
antenna cable still to do.

New whip antenna in place.

Dash top panel recovered before fitting.
