All the air shows i've been to the Super Hornet and Legacy Hornet have used the VHF air boss freq. I guess it depends on where they're at. What venue and so forth. But all you'll hear on the air boss freq is the normal ATC duties for their perfomance. You won't hear anything to a spotter like the F-22, F-15E, and the F-16 uses which is the topic here. Why i don't know. I guess they figure they don't need one. As for the Legacy flights those are usually done on the air show discretes for the weekend and that range is usually between 122-124MHz range. But i've also heard them on the air boss frequencies too.
