ray70 pulling down seatalkng net

Hi,
i have a ray70 which i installed in 2015, and have updated the software in.
recently i stopped receiving all data from seatalk ng connected devices at my a75 and i70. after removing each device one at a time i found that everything worked properly when the ray70 was disconnected. the vhf radio appears to be working.

any suggestions? i beleive i registered the radio so it might still be under warranty.

thanks,
