Follow your instructions and get the Essex class carrier. But no luck with airbases when I use the preset channels.
Try to get the airbases manually with the C-26 remote controller. Found the airbases on following frequencies (if the ARC-5 shows frequencies) which not compare to the normal ATC frequencies found on the map.
ANA 225; map. 250
KRD 238; map 251
Nov 249; map 252
Kry 261; map 253
MAY 275; map 254
Think there is a problem in the programming of the navigation radio.
