Sens. Jerry Moran (R-Kan.) and Tom Udall (D-N.M.) have added their voices to those of broadcasters and others asking the FCC to be careful how it allows new users to share the C-band spectrum they use to receive programming networks from suppliers.

"As part of its proceeding, the FCC must consider whether sufficient spectrum will remain available to accommodate today's C-band services, whether other transmission capacity could provide an equally reliable, available, affordable and resilient alternative, whether new uses of the band could result in harmful interference to existing services, and how to reiumburse C-band earth station operators for costs incurred," they wrote FCC Chairman Ajit Pai. 

Broadcast and cable voices calling for caution praised the addition to the chorus.
