KMI, Dixon Radio, CA
KMI was the west coast radiotelephone station of AT&T. It's sister stations on the east coast were WOO and WOM. They provided voice telephone service to ships at sea, first via AM and later via SSB.
KMI was established in 1921 with its receive site at Point Reyes, just to the west of the RCA receive site. Transmitters were inland at Dixon, CA.
The station also had a point to point component providing trans-Pacific voice circuits as well as ship to shore service.
The 1939 "Berne book" lists KMI as having five AM HF channels.
