Subject: Information from Radio Sources Other Than the Federal Communications. Russ The German military now occupying the itussian city of Kerch appear to be operating the former Russian wireless channels of that city under their original calls, U:G-2 and UKG-3, both of which have been observed calling DLL, Berlin. UKG-3 was heard trans- mitting five-letter groups. Tires and frequencies have been recorded on both. The German operators were inexperienced, and the signal tone very rough, indicating that the original transmitter was }rotably de- stroyed by the Russians. Finland last week direct radio traffic between Italy and Finland were heard. much of it in the clear in German and Italian. From both the increase and nature of the traffic and sore of the content in the clear text, it would appear that some Italian troops are operating; in Finland. Turkey The German Gestapo circ omits from Turkey to Hamb.zrg have been terrifically active. The frequency of two rain circuits are recorded, together with one rather permanent tire sched -:le. Jai an Frequencies, hours, dates, call letters, etc., have been noted with regard to the various Japanese traffic, particilarly APPROVED FOR RELEASED DATE: 09-Jun-2009 that frog. Station C'LA2, Santiago, Chile. Ienerally. this traffic is Japanese dirlomatic ;oin; to and fror. the Fore-;n Office and the anbassies, Japanese r.i itary (;lar Department and Attaches) and Japanese Naval (Navy Department and Attaches). Consular and other types of messages have been heard clearly on many frequencies and times iron some one hundred points in Japan. China and the Ditch Last Indies. fost of the traffic has been in five Roman letter groups and in numeral groups sent in Japanese short signals. Some Japanese front line messages in Yana have been heard and their frequencies and hours. etc., noted. LSflhanistan Considerable increase in traffic has been observed between Station DFC, Berlin and WAX, Kabul, Afghanistan, with "rush" traffic. It would seed worth while nder the circacstances to watch well be connected with possible impendin thrusts of the Axis in Egypt and beyond and the prospect of some future iossible drives of the Japanese India-ward, South America At the moment there is a great amount of caution by Gestapo agents in the S.''estern Hemisphere. However, some twelve Gestapo circuits have been heard, rost of them, with changing calls but with TNT, UCH, and BX7 frequently occurring. Freouencies have been recorded, but there is considerable change as to time schedules. Chile Since the entrance of the United States into the war, Santiago, Chile, appears to have become the channel through which the bulk of communications from the 7'eetern Hemisrhere has been and is being transmitted to Japan. On the day we declared war, a mes- sage was intercepted going frog.tLexico City to Tokio, a message in Spanish from the Japanese Ambassador to the Japanese Foreign Office. in which the Ambassador stated that the ;'exican Government would per- tit the transmission of radiograms only in the clear - in Spanish or dnglish. This situation would appear to have caused the Japanese Government to turn elsewhere for an outlet unrestricted in this re- gard. Within a few days, Santiago, C?.ile, became: very active on its short-wave circuits linkin;; Tokio. This develo,ment vas reported by the radio source involved to a overnnent official presumably competent to initiate the necessary action. The Atlantic an the gripbean The German Transoceanic News Service's daily trans- mission over short-wave wireless telegraph station 011:, Berlin, has made a significant departure from its routine ly interspersing Nazi Government secret messages, comprised of five-ntmber ;roups. The press sequence is interrupted by a call :E'SER/ DONAU AMSER/DONAU WESER/DONAU and then messages of frog. one hundred to one hundred and fifty groups are sent. It has been learned from a reliable source that these words were used by the German Government in 1917 and 111# to designate encoded and en- ciphered messages transmitted to German submarines. It will be recalled as having been noted in the F. C. C. reports that direc- tions and information have been broadcast on "voice" radio, apparently intended for submarines in the Atlantic and Caribbean. It would also appear likely that the cryptograms hidden in press traffic are also intended for submarines.
