The radio service of the _Corsair_ in the war zone was so important and essential a part of her activities that a description of it in some detail seems well worth recounting. Chief Radio Electrician H. F. Breckel went to the trouble of preparing a narrative which reads as follows, and it goes without saying that he was the man best fitted to undertake such a task: I reported on board the U.S.S. _Corsair_, then at the Navy Yard, Brooklyn, during the last week in May, 1917, in accordance with orders from the Bureau of Navigation. At that time I was attached to the U.S.S. _Ohio_, then at Yorktown, Virginia, which was the war base of the Atlantic Fleet. Reporting to Ensign Gray, Communications Officer of the _Corsair_, I was told that I would be in charge of the operation of the radio department and to get things in shape for a long cruise away from any established base of supplies.

BRECKEL, CHIEF RADIO OPERATOR] [Illustration: ELECTRICIANS SWAN AND PLUMMER, OF THE HIGHLY EFFICIENT “RADIO GANG”] My first step was to make sure of a personnel which would furnish efficient service under all conditions. Four operators were necessary and this number was soon sent to the ship, and a better group of men could not have been found in any vessel. The radio force comprised: Ensign Gray, U.S.N.R.F. (Radio Officer) Harry F. Breckel, U.S.N. (Chief Electrician, Radio) James A. Plummer, U.S.N.R.F. (Electrician, 1st Class, Radio) Meriam H. Swan, U.S.N.R.F. (Electrician, 2nd Class, Radio) Ivan E. Davis, U.S.N. (Electrician, 2nd Class, Radio) Each man was given a thorough examination when he reported on board and the results indicated that all of them were proficient and reliable operators. We promptly set to work and the radio-room fairly hummed, day and night. The transmitting apparatus was inspected, calibrated to the proper wave lengths, and tested. The receiving apparatus was also overhauled, minor repairs made, and adjusted to receive the various wave lengths used by other U.S. naval vessels. Then the inspection included the various switch-boards, storage batteries, heating and lighting systems, motor generators, etc. The radio-room was located on the main deck with doors opening directly on deck, so it was necessary to devise a lighting circuit which should automatically switch off the lamps when the doors were opened, as the ship moved in total darkness. After stocking up with spare parts, the antenna was given careful attention, for nothing is more exasperating than to have your wires carry away and to have to replace them in heavy weather.
