The FBI’s investigation into the assassination of Leo Ryan and the deaths of Peoples Temple members in Guyana on November 18, 1978 included many contacts with amateur radio operators – hams – who had listened in to Temple radio conversations or who had been in touch with the Temple themselves. For the most part, these contacts reported little more than the dates and summaries of the conversations, all of which were before November 18 and most of which had no bearing on the events of that day. Because of that, these serials have not been transcribed.
Serial 1651 reports on one of those radio contacts. The pdf of the serial is here.
