My involvement with the plans to assassinate John F. Kennedy commenced at the end of June, 1963. On July 1, I was contacted by (CIA head of Domestic Operations Officer) Tracy Barnes. He requested that I purchase four Mannlicher 7.35 mm surplus rifles. According to Barnes, the rifles were available in the Baltimore area from Sunny's Supply Stores. Upon my agreement to make the purchase, Barnes requested that I alter the forepiece of each rifle so that the rifles could be dismantled, hidden and reassembled quickly. I thought this last request odd until I was informed that the rifles were to be used for a clandestine operation.

One day later I received a second phone call. It was Eladio del Valle calling from, I assumed, Miami. He asked me to supply him with four transceivers which were not detectable by any communications equipment then available on the market. Although his request seemed impossible, I told him that I had an idea which might fulfill his requirement. I could provide him with sub-miniaturized units whose operation would be confined to a range of fifty or one hundred kilohertz. To operate any sizable distance, the units would require an antenna at least several feet in length. A wire taped to the user's leg would easily suffice for this purpose. The set-up would not be pretty, but I could assure him that no one would be monitoring these low frequencies.

Del Valle then requested that I deliver the transceivers and the rifles to David Ferrie. I was surprised by Ferrie's involvement in the transaction. Barnes, in our previous conversation, had neither informed me that the rifles were being made for Clay Shaw in New Orleans nor that David Ferrie would be the person responsible for picking them up once I had completed the required alterations. Del Valle explained to me that the rifles and communications equipment were for his Free Cuba Committee, and that Clay and Ferrie were assisting him in the operation. I assured him that the equipment would be ready on time as I would immediately order the Motorola-made special transceiver units. Motorola was manufacturing the units for railroad communications equipment; they were relatively easy to secure.

The radio transceivers for del Valle were more difficult to create than I had originally thought they'd be. An unusual amount of power was required for them to transmit over any significant distance. To solve this dilemma, I included an extra pack of four "D" type battery cells to be used for transmitting purposes only. The pack was plugged into the transceiver unit and could easily be carried in the user's pocket. Ironically, I later learned from del Valle that the transmission time was to be limited to five minutes, which meant my additional adjustments had been unnecessary.
