FCC Grants Waiver to Vertex Standard for 2 UHF Radios

The FCC granted Vertex Standard a waiver of the requirement that Part 90 certification applications in specified VHF and UHF bands must include a 6.25-kilohertz operating mode or equivalent efficiency.

Vertex requested the waiver for equipment certification applications for two 5-watt 12.5-kilohertz UHF radios that are not capable of operating in a 6.25-kilohertz operating mode.

The FCC rules state that applications for Part 90 certification of transmitters designed to operate in certain VHF/UHF bands filed on or after Jan. 1, 2015 — an extension of the original 2011 deadline — must be capable of meeting a spectrum efficiency standard of one voice channel per 6.25 kilohertz of channel bandwidth or equivalent efficiency.

Vertex said it successfully completed and submitted applications for four out of six products in a new product line, without 6.25-kilohertz capability, prior to the Jan. 1, 2015, deadline. With respect to the other two models, the vendor said it submitted equipment to the test facility early enough for an application to be submitted before the deadline, but the test facility unexpectedly requested additional material, which delayed the completion of the testing.

Because of the delay, Vertex was unable to submit equipment approval applications for the two models before Jan. 1, 2015. Therefore, Vertex sought a waiver for the two remaining models in the product line without 6.25-kilohertz capability.

The commission said in a letter to Vertex Standard Executive Manager Yukimasa Tomita that Vertex presented sufficient facts to meet the high standard for grant of the requested waiver.

“The supplier has shown diligence in planning and has invested substantial resources in its new product line,” the letter said. “If the waiver were denied, Vertex would continue to market its existing products without 6.25-kilohertz capability, but, according to Vertex, ‘rejecting the waiver request would deny users the benefit of using radios with improved performance and design. It would also require Vertex Standard to develop new devices to replace the VX-264-G6-5 and VX-261-G6-5 outside of the company’s typical development cycles.’ ”

The FCC also said that users seeking 6.25-kilohertz capability can obtain such equipment from Vertex and other manufacturers.
