While serving in the Navy on a destroyer as a Radioman 2nd we used the R-390-A with the WRT-2  "T-2" and an LS-474 bulkhead mounted speaker or headphones when operating CW in a net. Usually the RM1 would also monitor comms via speaker, you seldom saw the RMC/Chief Radioman unless he showed up to chew someone's unfortunate butt. We had R-1051's that were crap on CW, excellent on RATT. UCC-1 multichannel RX KWR-37 or the old Orestes KW-7 ship/shore URA-17 if my decades old memory is functioning... There was a URC-35 T-827?/R-1051 transceiver for HiComm SSB if I remember right..
