Can anyone help. My radar seems to be working OK but I get no
targets, Not even land. What should I check ???

One common situation on the 1830 was (is) caused by turning the "A/C
SEA" control "up" (or clockwise) and effectively eliminating close-in
targets. This is the center knob of the three at the top of the control
panel. Make sure the knob is in the "out" position too..... that is, not
pushed "in".... (sort of a dual function knob)
This is a simple tip, and certainly does not replace the good advice
from Bruce from Alaska!
