LMCC Responds to TV Station’s Request to Switch Channels
Wednesday, May 19, 2021 | Comments

The Land Mobile Communications Council (LMCC) filed an ex parte letter with the FCC responding to a reply from the KTUL television station in Tulsa, Oklahoma, concerning KTUL’s request to switch channels.

In April, KTUL filed a request to substitute its current channel 10 with channel 14 in the Digital Television (DTV) table of allotments for the area. The LMCC filed opposition to that request, arguing that approval of the request would pose an “unacceptably high risk” of causing interference to protected land mobile operations.

In its response to that opposition, KTUL said that in its request it had acknowledged the possibility of LMR interference and had committed to using a filter to prevent that interference and other necessary steps to limit interference.

“LMCC, however, requests that the commission impose additional requirements, which have no basis in commission rules or policies,” KTUL’s response said.

In its ex parte letter, LMCC questioned whether the proposed steps would actually prevent interference.

“Contrary to KTUL’s proposed interference mitigation solutions, the LMCC stated that land mobile receiver filtering was not a practical solution given the number of fixed and mobile devices that would be involved and asked who would be responsible for the costs associated with that approach,” the LMCC said in a statement. “It requested the FCC to conduct its own investigation of the availability of alternative UHF channels for KTUL’s use.”

In its letter, the LMCC also requested that if the FCC decides to grant the request, it require KTUL to address the land mobile interference concerns through on-air testing and said the TV station should not be granted programming authority until the interference concerns are resolved.

“There are several hundred land mobile incumbents who could be impacted by the operation of this proposed high-power transmitter,” the LMCC’s statement said.
