Just found this jewel:

CTG 77.4 comments:
1. FM2 and TBM aircraft of TG 77.4 were equipped with WE-233A, and F6F 
aircraft with AN/ARC 5. Because of the large number of carrier divisions 
involved and the resulting variance in crystals, three VHF frequencies only 
were available for aircraft operations. These were 140,58 mcs (channel 1), 
142.02 mcs (channel 2), and 142.74 (channel 4). Channel numeral designations 
were made in accordance with the "old" Navy system, and promulgated by 
dispatch in order to aid CSA and the FDOs in designating operating 
frequencies. This method of designating channels was necessary owing to the 
confusion resulting from the various systems in use and was determined in 
conference with all task unit communication officers as most convenient.
