Field Day V/UHF contacts are point to point, not through repeaters. I don't really think the higher frequencies are an issue. Big operations that are looking to maximize every point possible will be running there, but from an interest standpoint, it's very boring just doing ground line of sight contacts. There will be some e-skip activity on 6 by that time, that's about it.
I know, I was saying that I would use the repeaters on the 13th just to see what kind of range I could get from the club.
