Hi all.
Today, when taxiing out at Bankstown, Tower advised almost unreadable on ground freq 119.9.
A check on Tower freq 132.8 OK initially, then unreadable 5 min later.
Radio Techs removed Radio and checks perfectly on the Bench.
Reception fine and Sidetone fine. Just transmit probs.
Later on ground checks, transmit distorted on lower freq but twr reading loud and clear at higher freq 132.8
Ground test of Antenna OK.
Problem just appeared today and no issues since Radio installed new in late March this year.
Am using latest David Clark DC-PROX ANR Headset but problem still there on old Headset and no improvement on copilot side.
Appreciate comments guys.
Cheers Roscoe
