It is the upgrade to C-145/147 (not ADS-B) that has enabled ASA to pull out navaids, saving a fortune for ASA, at the cost of transferring huge costs onto the aircraft owning/operating community, across the board.
Saving a fortune for ASA?? I suspect that the big end of town said that they don't need, don't want and won't pay for the NDBs around the country. Just goes to show that the user pays model for aviation infrastructure is flawed.
