Aircraft; Human Factors; Procedure
We experienced VHF data packet bursts interfering with primary communications during landing. We were in the last stages of a night visual approach into DEN on final for 35R. Our altitude was between 200 and 300 feet AGL transitioning to the landing phase. The aircraft was fully configured for landing. VHF comm 1 was selected for both receiving and transmitting and was tuned to Denver Tower on 133.3. VHF comm 2 was tuned to ARINC and deselected. VHF comm 3 was in its normal data mode and deselected. All other settings were per SOP. The data bursts were easily heard on the active comm 1. There were three bursts total; similar in sound; each lasting less than two seconds and occurring successively. One burst blocked a portion of Denver Tower's transmission; however; the transmission was not intended for our flight. The other two bursts occurred during radio silence between transmissions. The bursts were consistent with the sound of ACARS transmissions or other VHF packet bursts. We didn't experience any other radio anomalies during our two legs that day on that specific aircraft. This is not the first experience I've had with these bursts; merely the first that I tracked data for. Previous experiences occurred in nearly identical positioning of the aircraft on final approach into Denver.
A319 pilot reported VHF communications were interrupted by data packet bursts on short final at DEN.
