In case of team flying, the intent of air-to-air communication should be voice only. Please do not promote any more "eyes to the panel" electronics; there are two many already.

Best case would provide a private voice frequency for each team. Therefore, the most case scenario would be total entries divided by two. For a big regional or a national contest a reasonable number would be 35 frequencies. An international contest would require more.

Again, no more "eyes to the panel" electronics please.
