## Discrepancy

NR 2 COM INTERFERENCE ON FREQUENCY 127.975.  INTERFERENCE IS COMING FROM BOTH AZ-810 ADC'S. HONEYWELL TECH SUPPORT INSTRUCTED ME TO INSTALL FOIL TAPE ON ADC EXTERIOR PANEL SEAMS TO ELIMINATE PROBLEM.  THE ADC'S SHOULD BE REPAIRED OR MODIFIED INTERNALLY BY HONEYWELL TO ELIMINATE RF INTERFERENCE.
