Sen. Ed Markey, D-Mass., is spearheading a letter to the FCC backing the reserve of spectrum for some carriers as part of the broadcast-TV incentive auction it plans in mid-2015, his spokeswoman confirmed Tuesday. That letter is expected to be sent to the agency Wednesday morning, she said, and is similar to a letter House Democrats sent to the FCC earlier this week (CD May 13 p7). Markey’s spokeswoman declined to say how many signatures this Senate letter may have. The FCC is expected to vote on an incentive auction item at its meeting Thursday.
