In September 1972 [REDACTED] Memo to conduct hearability
testes of certain HF long-distance commercial telephone circuits
between the US and South America. The circuits carried drug-
related traffic. [REDACTED] The tests were successful. The activity
was terminated on 30 Jan 73 following CGC determination that they
were illegal.

We conduct an intercept operation in [REDACTED] targeted
on radio telephone conversations. [REDACTED]
These intercepts contain a
large number of unrelated conversations often involving US citizens.

Testing in the US of OID-developed electronic collection
systems will result in the collection of domestic telephone
conversations. When the tests are complete, the intercepted
material is destroyed.

CIA [REDACTED] technicians conducted tests in the Miami area in
August 1971 OF OF gear intended for use against a Soviet agent in
South Vietnam. While wholly innocuous, the tests preceded the
holding of the conventions there and could be construed as
being somehow related to them.

In February 1972 CIA asked an official of AT&T for copies of
telephone call slips relating to US-China calls. The operation
lasted for three or four months and then dried up. CGC stated its
belief that the collection of these slips did not violate the
Communications Act since eavesdropping was not involved.

Page 29        Mail coverage

Since 1953, CIA has operated a mail intercept program of
incoming and outgoing Russian mail and, at various times, other
selected mail at Kennedy Airport in New York City. This program
is now dormant pending decision on whether to continue or to
abolish it.
