## Discrepancy

RNA-34BF "LOCKS UP" WHEN IN VICINITY OF FM RADIO STATIONS BROADCASTING ON 107.9 MHZ.  INDICATIONS TO THE USER ARE THAT THE RADIO CANNOT BE TUNED TO ANOTHER FREQUENCY AND ALL OUTPUTS BECOME FROZEN OR ABSENT.  MFG HAS BEEN MADE AWARE OF THE PROBLEM BY CANADA, SWEDEN, AND NOW US FLIGHT INSPECTION ORGANIZATIONS.  INITIAL PROBLEMS REPORTED AT LEAST BY 2008, BUT NO RESOLUTION YET.
