My Ratheon CL70 radar system (5 years old, approx. 4,000 hours of
usage) showed the following malfunction: When I would change the
range from 3 to 6 miles and vice versa, the screen would go blank for
from 3 to 5 minutes. Upon inspection, the local Raymarine rep. said
that the antenna drive belt was seriously deteriorated and was
failing. While I accept that the belt was bad, does changing the
range have any impact on the drive belt? Any suggestions as to other
possible causes of this malfunction. Thanks, Steve L.
