Blue angels

[DQ]

I attended the 2017 Fleet Week in San Francisco October 7-8, 2017. The Blue Angels used a frequency referred to as Comm Channel 20. The frequency was 246.500 MHz (AM). I've collected their frequencies for years and this one was not on my list.

346.5 CH. 18 was referred to as "Start-up"

Sounds like you came upon a new one.
And what you found is indeed 2xx.5 not 3xx.5?
