Just installed a 1623 and followed all directions implicitly. Radome is mast
mounted - 10M cable through the cabin
and wired up.
It turns on, warms up, and I can hear the thing rotating up there when I switch TX on, but there are NO RETURNS! I'm in my marina and there is stuff everywhere, yet zero returns on the screen
Scanner test mode shows 41RPM, and scanner OK (cd) whatever that means...
What's going on here? Did I miss something? I'll call furuno
next but was hoping somewhere out there may have a quick remedy.
