amendment SF 1449 N6883625QS070 0001.pdf

This document is an Amendment of Solicitation/Modification of Contract (Standard Form 30) for Solicitation Number N6883625QS070, dated 25 Jul 2025. The amendment publishes a list of questions and answers from vendors regarding a UHF-band radio installation project for three Helicopter Maritime Strike Squadrons (HSM-40, HSM-48, and HSM-50) located at Naval Station Mayport, Florida.

The vendor Q&A clarifies technical details about the radio system, including: no specific digital format is required, radios will only communicate with aircraft (not other stations), remote control is limited to two locations within the same building, and the system will use a single frequency of 250.9 MHz. The current infrastructure consists of Motorola brand base stations estimated to have been installed in the 1980s. The frequency range covers 250.9 MHz, which falls within the UHF military band between 225-399.9 MHz, and is intended to provide continuous ground-to-air communication for three squadrons, with each squadron requiring two UHF-band transceiver units and associated antennas.
