Thanks LukeFF and JChanning,
My issue is that with
only the v1.3 SD radar I was
NEVER attacked by aircraft. Even when going 7600x in time compression, the SD pulls the time compression down to 8x which I then stop and figure what the 'bogey' is. When I click on the unknown 'bogey' it usually says 'very fast' so that is my first clue about it being an aircraft. Japanese hovercraft and hydroplanes very limited in WW2 IIRC:rotfl:.
With the SD + SJ combo I am subject to aircraft attacks again which makes the SJ totally worthless for me

. It's not like I wasn't finding anything to shoot at using only sonar contacts.
