The Ambassador in Mexico ( Daniels ) to the Secretary of State
[Received April 2.]
Sir: With reference to the Department’s instruction number 607 of February 6, 1935, with regard to interference between the radio broadcasting stations KPRC in Texas and XENT in Nuevo Laredo, Mexico, I have the honor to report that the Radio Communications Section of the Ministry of Communications has replied to the Embassy’s representations in this matter, that the frequency of Station XENT has been permanently changed from 1115 kilocycles to 910 kilocycles and that the Bureau of the International Telecommunication Union has been so notified. The Chief of the Radio Communications Section declined to be impressed with any arguments as to the serious interference caused American stations by this change in authorized frequency. Mr. Galindo, Chief of the Section, pointed out that there is a spread of 10 kilocycles between XENT and KPRC, which should be sufficient, and said furthermore that he had notified the Mexican station to adhere strictly to this new frequency.
As having some bearing on the difficulties encountered by the Embassy in this case, it has been reported that the powerful station XENT at Nuevo Laredo is frequently hooked up with the broadcasting station XEO, owned and operated by the National Revolutionary Party, the dominant force in Mexican politics today.
