M25 is the ENIGMA designation of a former radio communications network, operated by the United States Government.

Information about this radio network was first published by Harry Helms [1] in 1980. Helms stated that is was an operation of the State Department Intelligence Service (possibly meaning the Bureau of Intelligence and Research). He listed the following stations:

  • KKN50 - Washington DC
  • KRH50 - London, UK
  • ACN - La Paz, Bolivia
  • KKN44 - Monrovia, Liberia
  • KWS78 - Nicosia, Cyprus

The stations intially operated in Morse code while later they started using RTTY as well.

Don Schimmel published a QSL card sent in 1985 to Patrick O'Connor by KKN44 [6], on which the station is idntified as "Regional Relay Facility, Monrovia, Liberia, Diplomatic Telecommunications System". Schimmel added a new station to the list, KKN39 in Miami, FL and corrected the location of KWS78 as Athens, Greece.

According to Ary Boender [7], officially, KKN50 was operated by the National Communications System (NSC) for the US Department of State. It was the CIA however who was running the show. KKN50 used at least one of the facilities of the Warrenton Training Center (WTC). Warrenton has/had five sites, 'Station A', 'Station B', Station C', Station D', and 'Station E'. WTC 'Station C' is located near Remington and is one of the homes of 'The Counting Station' [E05/V05]. The Office of Communications (OC) used 'Station D' at Culpepper, VA, as relay center and it was also the site that was used by KKN50.

KKN50 was but one of the many stations in the network. In official publications the stations were often listed with fake locations. A couple of the most active stations have been figured out over the years, though. One of the most active stations, besides KKN50, was OC Miami with callsign KKN39. Their routing indicators were RUEG and RUEGMI. Incidentally, the tactical call of KKN50 was BRANDY and its routing indicator was RUES. KKN44's signal was also found as part of VOA's feeder signal.

The network was last heard in 1997.

The main players in the net were:

KKN [M25] network
Callsign Location
KKN39 Miami, USA
KKN44 Monrovia, Liberia
KKN50 Washington DC, USA
KRH50 London, UK
KWS78 Athens, Greece

Besides the numerous CW and RTTY transmissions of the main players, sometimes also other callsigns were logged:

  • KUO29 clg KKN39
  • KKN50 clg KWT91 KRC81 KWT94 KWY29 KPH7 KKN44
  • KWT91C clg KKN50
  • KKN44 clg 9GV
  • KGN clg KKN50

In addition to the callsigns mentioned above, several publications have listed a larger number of stations, stating that they were part of this network too. I could not find any logs of these stations though, which does not mean that they did not exist of course. Ary Boender has made a compilation of all the callsigns that were mentioned, in the following list.

  • KGN
  • KGO50
  • KKN32 Washington, DC, USA
  • KKN33
  • KKN35 Washington, DC, USA
  • KKN36
  • KKN39 Miami (possibly beamed to Central and S. America)
  • KKN40 Monrovia, Liberia
  • KKN41
  • KKN42
  • KKN43
  • KKN44 Monrovia, Liberia
  • KKN46 (Possibly beamed to Central and S. America)
