Here is the Andy Airshow report from our anonymous contributor (and thanks a million for sharing).
123.4750 MHz -- Golden Knights. Communication between the ground and jumpers giving wind speed and conditions etc.
141.0750 MHz -- Victor channel simulcast
235.2500 MHz -- T-Birds solos. Also monitored the pre-flight brief (high show etc.) and their pre-show "poem."
235.2500 and 379.2000 MHz -- T-Birds traffic. Unfortunately I didn't note which of these two was the primary air-air for the formation flying. I heard all of it, so it has to have been on one of these two.
413.2750 MHz -- T-Birds ground team at the comm cart communicating with team prior to take-off (mentioning lots of FOD on ramp etc.)
