And you're running RSRD?

TMO and RSRD

You should at least run into several dd's patrolling truk. Also, always look in the shallows to the east.

Did you go past the reef into the atoll. The mountains block radar and you have to get the right angle. The last I looked in the ME almost always a Yamato and Fuso there. I think in May and June it's full of TF's.

ran around everywhere, even the harbors where empty.
