The U.S. Government is seeking sources to procure four RT-5512 dual-band transceivers for the Bullseye Radio Network at Yakima Training Center and Joint Base Lewis-McChord, with the intent to support a competitive procurement. The radios must operate from 30–512 MHz, be controllable via external interfaces, support ED-137 VoIP, include a 70 MHz IF port for GPS synchronization, and meet specific power, rack-mount, and dimensional requirements. This is a sources sought notice for planning purposes only—it does not constitute a solicitation or commit the government to award a contract. Interested businesses are asked to submit a capabilities statement (maximum two pages) that details relevant experience, commercial availability and pricing, and any small business status or certifications. All responsible firms, including small businesses in all socioeconomic categories, are encouraged to respond to help the government determine how to structure the requirement.
