Summary:  
The document details audio surveillance activities conducted at a SAS safehouse in Bethesda, Maryland, during July 1963. The subject under surveillance left Washington, D.C., on July 13, 1963, while the property owner, Fred C. Thomas, vacated his residence on July 12, 1963, to relocate to a PCS assignment. Case officer Charles Matt coordinated surveillance efforts, including requests for audio monitoring of the subject’s conversations with an individual named Quintero during the absence of SAS case officers. Technical preparations involved setting up equipment in designated rooms (floor living room, bar) and a crawl space over a gorge, with instructions to lock the area and service recording devices as needed. A cover story was devised for an agent working on the property, claiming he was assisting a Washington state estate agent, R. Cortland, in managing transient clients. The document also notes the involvement of Rafael Aurelio G. Guitero Tarrable returning to Bethesda on July 29, 1963, and mentions technical specifications for audio equipment, including VORs obtained from Francana.
