Amateur Radio Activities
(From the NSA Handbook)
Amateur radio (ham radio) activities are known to be exploited by hostile
intelligence services to identify individuals with access to classified
information; therefore, all licensed operators are expected to be familiar
with NSA/CSS Regulation 100-1, "Operation of Amateur Radio Stations" (23
October 1986). The specific limitations on contacts with operators from
communist and designated countries are of particular importance. If you are
an amateur radio operator you should advise the Security Awareness Division
(M56) of your amateur radio activities so that detailed guidance may be
furnished to you.
