The FCC would rather auction spectrum to the cellular telcoms rather than consider what is best for all spectrum users.* Amateur radio is an extremely low priority to the FCC* Traditional business land mobile radio has been replaced in the age of digital mobile phone communication.  * The FCC has been downsized with reduced staff and fewer field offices* Influx of a magnitude more cheaply made Chinese import electronics overwhelm the FCC type acceptance office.
