July 19, 1994 FIELD OPERATIONS BUREAU ACTIVITIES FOR THE WEEK OF JULY 10 SECRET SERVICE INTERFERENCE: Officials from the White House Communications Agency contacted the Denver Office last Thursday to complain about interference in the Denver area. They told FCC engineers that communications equipment used by Secret Service agents protecting the Vice-Presidential motorcade was seriously affected by unknown signals on two frequencies. FCC investigators using direction-finding techniques identified the problem as a common carrier paging transmitter in Cherry Creek, CO. The paging system license agreed to limit operations for the duration of the Vice-Presidential visit. INTERFERENCE TO FIRE FIGHTERS: The Douglas, AZ, office received a request from the U.S. Forest Service in the Colorado National Forest in Southeastern Arizona to help them eliminate a communications problem they were having with portable repeater stations they had brought into the area to coordinate fighting wildfires. The interference posed an immediate threat to the safety of the lives of the fire fighters and, using mobile radio direction-finding units, immediate action was taken by the FCC to trace the source of interference. ABANDONED RADIO STATION: Recent field surveys have indicated that many AM directional stations are not properly maintaining their signal patterns. As a result, FCC inspectors have been randomly inspecting these stations to encourage compliance. Last week, the Dallas Office sent an inspector to Denison, TX, to check an AM/M station and was surprised to find that the station was operating completely unattended. The station did not change to its nighttime patter, had no Disc Jockey, and no one watching the EBS receiver. Pre- recorded programming and commercials were brought in periodically by an employee, but the station had no telephone or apparent contact point. FCC inspectors finally tracked down the station manager who explained that times were hard and he had to lay off the station's employees. A violation notice is being prepared and further action will be coordinated with the Mass Media Bureau.

FCC inspectors inspected the shipment and uncovered approximately $250,000 worth of CB radio equipment that had been modified to operate on several out-of-band frequencies. Additionally, Customs has issued a recall order to the importer for an additional four shipments that had been released prior to the FCC investigation. The FCC and Customs authorities are considering whether to have the equipment destroyed. -FCC- News Media contact: Patricia A. Chew at (202) 418-0500.
