This verification letter is for a reception made in Seoul of their 648 kHz outlet. The station was administered by the Air Force’s Pacific Broadcasting Squadron.
Their MW outlet could be heard in Korea without much of a problem when the station in Russia was off the air.
Today, the station is called AFN Okinawa or Surf 648. Since the station in Russia on 648 is no longer on the air, it is an even easier catch in Seoul.
