We are pleased to announce the release of the February 2021 edition of the monthly TSCM | SIGINT newsletter. This edition of the newsletter discusses the procurement of Test & Measurement equipment vs the incremental investment in advanced Software Defined Radio (SDR) technology. There is a growing demand for advanced threat technology detection and identification across the radio-frequency and power line infrastructure that simply cannot be accomplished with obsolete spectrum analysis concepts and equipment designed for other industries. The Kestrel TSCM Professional Software is an innovative TSCM specific, operator centric software far beyond any other competitive product.
