Radar interferring with VHF

[jdfnav69]

I developed a problem about a month ago with my radar interferingwith a few channels on my VHF. I installed a LORAN on the boat yesterday. In doing this I pulled the radar and VHF out of the electronics box. When I was working on the install I powered up the radio and radar and the interferrance problem was gone.

After I got everything reinstalled in the electronics box I powered everything up to check my work. Well the radar interferance was back again, and to make things worse the LORAN interferred with all VHF channels.

The radio, radar and LORAN all come from the same power source in the electronics box. When I initially purchased the boat the radio and radar played together just fine, now they don;t and the LORAN has made it even worse. Anyone know of a possible fix other than pulling a new power supply for the VHF?

My first instinct would be to check and see if all the shielding is grounded on all those wires and also check to make sure you have grounded all the grounds

Believe it or not it seems to have been caused by a weak house battery. I charged her up today and went from 11 volts on the supply to 13.8 and the interferrence went away.
