From The RadioReference Wiki
Coronet missions are those across the Atlantic/Pacific Oceans that are either delivering new aircraft or flights of aircraft rotating to/from overseas bases. If they can't make it on their internal fuel load, they are assigned a tanker(s) to fly along with them and provide fuel.
Those frequencies correspond to the suffix of the flight - such as TABOR 11. First, you look at the suffix. Since it's 11, their refueling freqs are the A (Alpha) set of freqs. There's a Primary and Secondary freq for the Alpha refueling plan. In the example, TABOR 11 would use the Alpha set of freqs - either 396.2 or 394.6.
A HURON 61 flight would use the Kilo set -- 343.1 or 322.8.
