One T-6 50-watt transmitter for 2,307 to 3,333 Idlocycles. This 

 transmitter was used for schedules with Winthrop radio station and 

 sending position reports, weather reports, and all ice information to 

 the Hydrographic Office. 



One CGR-18 direction finder. 



With her limited equipment the General Greene carried out as closely 

 as possible the schedules and broadcasts of the larger vessels on regular 

 ice patrol in previous years. 



Two ice broadcasts were sent daily on 705 meters after a preliminary 

 call on 600 meters. The broadcasts contained the position of the ice 

 observation vessel, weather conditions, and ice information. Each 

 broadcast was sent twice. In addition to the broadcasts, special ice 

 information was furnished all vessels requesting it. 



A summary of the ice information received each day was sent via 

 the Coast Guard radio station at Winthrop, Mass., to the Hydro- 

 graphic Office of the Navy at Washington. Also the Weather Bureau 

 was furnished weather reports daily. These messages were also sent 

 through Winthrop. On several occasions, difficulty was experienced 

 in clearing traffic through Winthrop. This was due partly to distance 

 but in most cases to static and interference. 



On the northern oceanographic cruise communication with Winthrop 

 was very difficult and a great part of the time impossible. When out 

 of communication with Winthrop, we relayed our traffic through 

 Labrador and Greenland shore stations and ships at sea. 



During the 5 months the General Greene was away from Boston on 

 ice observation duty no serious trouble was had with the radio equip- 

 ment. During this time she sent and received 3,668 messages totaling 

 179,586 words.
