EchoStar and SpaceX Both Say Record Backs Them in SCS PFD Limit Fight

Both EchoStar and SpaceX are pointing to the record on SpaceX's reconsideration petition concerning the out-of-band power flux density limit in March's supplemental coverage from space order as backing their opposing positions. There is ample opposition to the recon petition in the record, EchoStar said in a filing posted Tuesday in docket 23-65. SpaceX's lone supporter, T-Mobile, is partnering with it on SCS service and the carrier misunderstands how notice-and-comment rulemaking works, EchoStar said. The FCC wasn't obliged to put on notice in the SCS NPRM that it might adopt an aggregate out-of-band emissions limit, it added. SpaceX said the technical evidence in the record shows the need to reconsider the aggregate power limits. Band-specific limits "would respect fundamental physics," and there's no technical evidence supporting the arguments of backers of the aggregate limit, it said.
