Actually L is for L-band.View attachment 53820
Type 382 looks odd. One of the faces appear angled. I am not sure if the Type 383 label is being applied to the new radar or this Type 382 variant. The slots for the "L" there should not be for an L-band radar but for the IFF. One of the ECM units there, the smaller one, appears to be the same one used on the Type 056 corvettes.
