Spy and number frequecies

     We all know that the government listens in on just about everything we
do.  So why shouldn't you listen in on the government?
     The following is a list of CIA and foreign classified radio frequencies
including call sign, and times of best access.  A short wave receiver is
almost always necessary especially with the CIA.


     Due to the sensitive nature of this super-secret branch of the US govern-
ment, information regarding radio communication facilities is very scarce.
The listing below is a combination of ITU data and off-the-air monitoring.
According to the ITU, a power of 15 kilowatts is used for both CW and RSR/RTTY

     Nothing you can hear on short wave quite equals the cloak and dagger
intrigue of the so-called "Spy and Numbers" stations.  As incredible as it may
sound, the ordinary listener with modest equipment can hear signals intended
to convey vital information to spies, guerilla fighters, and every consider-
able type of underground clandestine political organziation.
     The majority of radio stations broadcasting such signals do so using
regular AM.  The trick is the spacial numeral code groups -- apparently
changed with every transmission.  Sophisticated techniques are becoming more
common including compressed CW send at speeds of 200 words per minute for tape
recording (it's reliably reported that Radio Berlin International transmits
compressed CW at various times during regular programming).  Obviously no ID
is given by the broadcaster and the "spy" is usually the only one who knows
what to listen to in terms of positive ID.
     The list below contains some of the more frequently heard stations at the
time of the publication of this file (1-20-86).  Frequencies and schedules are
subject to erratic and sudden changes.

     I hope you get as much information from these stations as I have, and
remember that certain people tend to frown on eavesdroppers so exercise some
