## Discrepancy

NR 1 VHF HAS INTERMITTENT SHORT BURSTS OF STATIC.  SOME JUST SECONDS APART.   REMOVED ANTENNA CONNECTOR WAS VERY CORRODED BUT ANTENNA CABLE AND CONNECTOR CLEANED OK WITH NO CORROSION.  TESTED CHF COMM L-C & R PER MM.  THEN TESTED ACARS PER MM.  C VHF ANTENNA REPLACED BECAUSE STATIC PROBABLY WAS COMING FROM ACARS TRANSMISSION FROM C VHF.
