The emergency radio room was located on the main deck aft and provided for emergency communications with the outside world in the event of the destruction of the main radio room forward. Originally the main piece of equipment in this space was the TCS radio transmitter and receiver. Also on display here aboard the SLATER, is the High Frequency Radio Direction Finder (Huff/Duff). The Huff/Duff was developed to intercept German radio transmissions from U-boats. The equipment, originally developed by the British, played an important role in the detection and location of German submarines during the Battle of the Atlantic.
Generally an effort was made to fit at least one ship in every escort division with Huff/Duff. As originally built SLATER was not fitted with Huff/Duff. However, because it was such a critical piece of destroyer escort history, when the opportunity came to acquire the unit, it was incorporated into the historical display.
