The Naval Air Warfare Center Weapons Division in China Lake, CA intends to sole source the procurement of Radio Frequency Spectrum Control TX/RX Eval Kits to Spectrum Control Inc. of Fairview, PA. This is because these specific kits provide the required non-fixed, fully customizable channels for a new system configuration. Any firm believing it can fulfill this requirement may submit a written capability statement for consideration within 5 days of the notice's publication. All responsible sources must maintain an active registration in the System for Award Management (SAM), which now requires a notarized letter for registration or renewal.
