AM Expanded Band Return Rule Challenged

Having been given expanded band AM stations, should companies that choose to keep them be obliged to give up their earlier frequencies as originally required?
Eleven broadcasters and four public interest organizations are asking the FCC to waive its rules that mandate expanded-band stations return either the new or the original frequency.
The group also is asking the commission to delay the effective dates of the give-back rule. At present, a station must decide within five years which AM license to give up.
