Advanced RF Systems & EW Solutions
for Contested Electromagnetic Environments
Yankee Actual delivers advanced RF engineering and electronic warfare capabilities to defense primes, government agencies, and commercial operators who demand performance in contested electromagnetic environments.
Founded by engineers with deep operational experience in signals intelligence, tactical electronic warfare, and SDR platform development, we bridge the gap between laboratory-grade RF performance and field-deployable systems that hold up under real-world conditions.
From custom waveform development on embedded platforms to full counter ISR and UAS system integration, we build solutions designed for the fight — not the datasheet.
Signals intelligence, spectrum monitoring, counter-ISR, counter radar, counter PNT, and counter-UAS datalink characterization. Waveform analysis and exploitation.
Custom waveform development, signal-processing pipelines, and platform integration on COTS and custom hardware — the engineering behind the EW Fabric that powers Spectral Warrior, with open Python control end to end.
Real-time waveform implementation on AMD/Xilinx Zynq-class silicon — including the multi-channel DRFM and AWG architectures fielded in Spectral Warrior Gen 2 — plus custom carrier board design.
Operations training for tactical electronic warfare personnel, delivered by instructors with decades of field experience spanning advanced EW, system design, and fundamental theory. Students train on real hardware and keep the full reference library sampled in Resources.
From analysis and rapid prototyping to field ready hardware and software, Yankee Actual delivers across the full RF system lifecycle — design, integration, test, and sustainment.
Flagship browser-based RF spectrum analysis and signal intelligence platform — real-time visualization, automated detection, emitter classification, and RF fingerprinting with native TAK / COT broadcast.
Explore PlatformOne node, seven EW modes, on commercial silicon — a palm-sized reconfigurable EW platform that senses, generates, and responds, controlled from any browser. Gen 1 & Gen 2 built and running.
PreviewSecure mesh remote-operation deployment — encrypted mesh networking for distributed, remotely operated systems in contested or expeditionary environments. Integration in progress.
PreviewCustom SDR application and hardware development — waveform and DSP pipelines, FPGA implementation, and carrier-board design for ADRV9009/9361 and RFSoC platforms. Integration in progress.
PreviewGeospatial FCC spectrum license survey — map and table view of licensed emitters by location, frequency, and IEEE band. PostGIS spatial search with Leaflet visualization and CSV export.
View ToolRadar system emulation for development and training — high-fidelity threat and target signal generation for test, evaluation, and operator training. Delivered with partner TactIQ Research.
Meet the PartnerYankee Actual offers operations training for tactical electronic warfare personnel — built around the contested electromagnetic environments operators actually face, not sanitized classroom abstractions.
Our instructors bring decades of field experience in advanced electronic warfare, combined with deep expertise in system design and fundamental RF theory. Students learn from practitioners who have built the systems, operated them downrange, and understand the physics underneath.
Curriculum spans foundational signal theory through advanced EW tradecraft, with hands-on instruction on SDR platforms, spectrum survey technique, emitter characterization, and counter-UAS workflows. Courses can be tailored to unit mission profiles and delivered at your facility or ours.
Condensed samples of the reference materials issued in Yankee Actual training programs — the complete references, with full signal-level detail, are provided to students as part of each course.
Frequencies, modulation schemes, and signal parameters across GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS, and SBAS constellations.
Open ReferenceSignal characteristics across all transponder modes — Modes 1–5, Mode C, Mode S, and ADS-B — with waveforms, code space, encryption, and timing.
Open ReferenceComprehensive datalink and control frequencies for UAS platforms — command links, video downlinks, SATCOM, and ISM-band control across military and commercial systems.
Open ReferenceSOLAS, solid-state Doppler, recreational, VTS, and beacon emitters — the maritime X/S-band environment from megawatt bridges to FMCW domes.
Open ReferenceTerminal, en-route, surface, precision-approach, and secondary radars — the air traffic control emitter set from ASR to Mode S.
Open ReferenceNEXRAD, TDWR, commercial, airborne, spaceborne, and profiler radars — including the highest-EIRP civil emitters in the spectrum.
Open Reference2G through 5G NR, cellular IoT, and satellite direct-to-device — bands, waveforms, duplexing, and power classes.
Open ReferenceWi-Fi, Bluetooth, IoT mesh, LPWAN, RFID, UWB, and short-range devices — the unlicensed signal environment every survey encounters.
Open ReferenceOpen-source survey of Russian early-warning, SAM, counter-battery, and strategic radar systems by band and role.
Open ReferenceOpen-source survey of PRC early-warning, HQ-series SAM, counter-battery, and strategic radar systems by band and role.
Open ReferenceOpen-source survey of European surveillance, GBAD, counter-battery, and BMD radar systems by band and role.
Open ReferenceYankee Actual was founded on a simple premise: the engineers who understand the electromagnetic battlespace should be the ones building tools to dominate it.
Our team brings deep backgrounds in military electronic warfare, software-defined radio platform development, tactical communications, and defense hardware engineering. We have operated in the same contested RF environments our customers face every day.
We operate as a lean, responsive engineering firm — no marketing theater, no bloated program offices. When you engage Yankee Actual, you work directly with the engineers building your system.
Clearable personnel available. ITAR compliance maintained. SAM registered for federal contracting.
