Earhart's last recorded radio transmissions in 1937

A radio log captured by the US Coast Guard vessel Itasca — which was waiting for Amelia Earhart off Howland Island in the Pacific with fuel — shows the final communications from her aircraft in July 1937. Earhart and the Itasca never made two-way voice contact and it’s possible Earhart never heard any of the Itasca’s transmissions.
