Think the 14 v batteries came from the days of Radair 360 Narcom 11A etc -
all the newer ones (last 20 years except possibly Icom A200) work OK on 12v
7ah batteries. I do suggest the big (long) 2 seaters use 16g wire from the
battery to panel exp Xcom as it is a powerful radio and you can get a power
drop. While going in Nimbus4 the aerial is in the rudder and a BNC at the
base of fin/rudder gets wet when you dump tail water. Please check each
annual and or do something as it will play up eventually!!! Ian McPhee
