</s>104-10179-10167 2025 RELEASE UNDER THE PRESIDENT JOHN F. KENNEDY ASSASSINATION RECORDS ACT OF 1992 RETURN TO CIA 3 fon.64 Background Use Only Do Not Reproduce, 3 Jan. 64 3 January 1963 MEMORANDUM FOR . Chief, Special Affairs Staff ATTENTION 1 Mr. A. Rodriguez ATTENTION i Radio Switch Equipment for Demolition SUBJECT i Radio Swatch Equipment for Demonolition Firing Purposes 3.1. After our conversation on this subject on 30 December, the question was discussed with Mr. (lay Alpera) TSD/AD/SDA), and Mr. Lee Poole (TSD/RTF), the following information (forwarded for your Poor's/TSD-RTF. The following information is for your discussion. 2. Mr. Alpern) Audio Operation Branch-composer, 7. components, under classified contracts with TSD, are two have experience, under classified contracts with TSD, in producing reliable equipment for this purpose of this part. They also, reliable equipement for this part, and also, they are also communications needs. These examples are: (Motorola, Chicago, Illinois) (Radio, Cambridge, Illinois ) The TSD VHF VHF with unique equipment for demolition was developed by (by(Motorolas), "Kell-Com) for transnationalized sets have developed by(Motorol, "Kells-Com" (transnationalized etc) have of other SAS projects. The special "need for demolition purposes) 3. In 3. The opinion of both persons consulted, the expenses noted in our first discussion was produced a reasonable amount of workable equipment of the crystal was capable of reliable, equipment for this sort of crystal tuning control for reason for reliability, equipment of this sort and forth tuning control of reason for reliably, selectively and rejection of previous signals. 4. Inherent equipment of Japanese or American manufacture in the citizen's band frequency ranges for toys, radio control devices, 61/1/1)

Summary: The document discusses the procurement and development of radio switch equipment for demolition purposes under classified contracts with entities like Motorola (Chicago, Illinois) and Kell-Com (Cambridge, Illinois). It outlines considerations for reliability, crystal tuning control, and security measures to prevent accidental laser triggers. Technical challenges include predicting operational reliability based on signal power, antenna orientation, and environmental factors such as building construction and radio frequency interference. The Quick Reaction Facility is noted as capable of producing small quantities of secure radio switches using commercially available components from manufacturers specializing in citizen's band frequencies, toys, and radio control devices. Recommendations for further discussion with audio technicians or engineers are included to address specific operational requirements.  

Key People: Mr. Alpern (Audio Operation Branch), Lee Poole (TSD/RTF), Austin M. Jones (C/TSD/CAB/SD)  
Key Locations: Chicago, Illinois; Cambridge, Illinois  
Key Events: Discussion of radio switch equipment development for demolition, evaluation of reliability and security measures, mention of classified contracts with Motorola and Kell-Com  
Key Organizations: TSD (Technical Support Division), RTF (Radio Technical Facility), SAS (Special Affairs Staff), CIA
