π‘ IQ Data: Real Physical Evidence You Can Use in Court
π§ Overview
When it comes to proving unlawful surveillance, electromagnetic harassment, or covert targeting, IQ data is one of the strongest forms of evidence a Targeted Individual (TI) or TSCM (Technical Surveillance Countermeasures) professional can collect.
β
IQ data is not just a screenshot.
β
It is a raw recording of the electromagnetic environment, captured to hard disk, fully preserving the signal’s frequency, phase, and modulation.
β
It meets legal standards for digital evidence β when done properly β and is admissible in court.
But even more important:
π― Your intent when recording is what makes it lawful.
Letβs break it all down clearly.
𧬠What is IQ Data?
Feature | Meaning |
---|---|
π§ “I” and “Q” Components | Every RF (radio frequency) signal can be broken into In-Phase (I) and Quadrature (Q) parts. Together, they describe the complete waveform. |
πΎ Full Recording | IQ data captures everything about the signal: frequency, phase, amplitude, modulation β just like recording live video, but for radio waves. |
π‘ Raw, Untouched Evidence | IQ captures the RF world exactly as it exists at a moment in time, without human filtering or editing. |
β This makes IQ data scientific, forensic, and replayable years later β like a frozen snapshot of the invisible world.
π‘οΈ Why IQ Data Is Considered Physical Evidence
β Direct recording of a physical event β The RF environment is real, and you are simply recording it like a dashcam records a traffic accident.
β Preserves full technical signature β Later, analysts can extract:
- Frequencies π‘
- Modulation types π
- Signal strengths π
- Source direction π
- Hidden content (audio, telemetry) ποΈ
β Tamper-resistant β Properly stored IQ files can be hashed (MD5, SHA256) to prove they haven’t been altered.
β Replayable and verifiable β Judges, defense teams, or technical experts can replay the RF signal from the original data β just like replaying a 911 call or video evidence.
βοΈ The Legal Foundation: Intent Is Everything
π― Hereβs the critical rule you learn in professional TSCM training:
You are allowed to record RF signals if your intent is to collect evidence, not intercept private communications.
β
Your purpose must be technical, defensive, and forensic β
not spying or eavesdropping.
β
Capturing illegal, suspicious, harmful, or unexplained RF signals is lawful under most electronic surveillance statutes β
especially when you record frequencies and modulations, not private voice conversations.
π Statutes and Legal Protections That Apply
Law / Statute | How It Protects You |
---|---|
π Federal Wiretap Act (18 U.S.C. Β§Β§ 2510β2522) | Illegal to intentionally intercept private communications β but capturing signal properties (frequency, modulation) without decoding speech is legal. |
π Electronic Communications Privacy Act (ECPA) | Protects electronic content β but passive RF environmental scans that don’t extract private content are allowed. |
π Federal Rules of Evidence (FRE) 901 | Digital evidence (like IQ recordings) is admissible if authenticated (proper logs, metadata). |
π FRE 1002β1003 (Best Evidence Rule) | Original digital files or properly verified copies are allowed in court proceedings. |
π ASTM E2815-11 (TSCM Practices) | Recognizes RF signal detection and technical sweeps as legitimate investigative tools, including logging anomalies. |
β Summary:
- RF IQ data = Legal forensic collection.
- Intent matters: record signals, not private conversations.
- Chain of custody and expert authentication make it courtroom ready.
π§Ή Surveillance vs Evidence Collection: Know the Difference
Surveillance (Illegal) | Evidence Collection (Legal) |
---|---|
π― Goal: Secretly monitor private conversations for gain. | π Goal: Lawfully document unexplained or suspicious RF activity. |
π― Captures: Content of speech or electronic communications. | π Captures: Frequencies, modulation patterns, energy levels β not decoded speech. |
π― Risk: Violation of privacy laws. | π Protection: Falls under technical investigation, like dashcams or security recordings. |
π― If your goal is honest forensic documentation of suspicious RF activity, you are operating within lawful protections.
π Real-World Example: TSCM Operations and IQ Evidence
Professional TSCM teams recording IQ data:
- Investigate hidden surveillance bugs π‘
- Capture illegal GPS trackers π
- Prove unauthorized microwave harassment β‘
- Detect foreign intelligence surveillance π―
β
They save full IQ files to hard disk
β
They document chain of custody (who collected it, when, where, how)
β
They present it as scientific evidence in corporate, civil, or even criminal trials.
π₯ How to Properly Collect IQ Evidence (Quick Guide)
Step | Why It Matters |
---|---|
π Document Collection Details | Who captured the file, device used, time, location. |
π΅οΈ Use Calibrated Equipment | Spectrum analyzers, SDRs (Signal Hound, USRP, Tektronix) properly configured. |
π‘οΈ Secure Storage | Write-protect media, make verified backups, hash files (SHA256). |
π§ Keep Metadata | Timestamps, device logs, antenna information, environmental conditions. |
π Avoid Intentional Content Interception | Don’t decode private phone calls unless authorized. Focus on signals, not conversations. |
π§ββοΈ Consult Expert Witnesses | RF engineers, forensic consultants can testify about your data’s authenticity and meaning. |
π§ Final Survival Takeaways for TIs and Investigators
β
IQ data = full, permanent recording of real-world electromagnetic events.
β
Captured lawfully with proper intent, it becomes strong court-admissible evidence.
β
Courts already accept digital forensics from radios, networks, GPS β IQ is no different.
β
TSCM professionals trust IQ capture as one of their primary evidence tools.
π― Bottom Line:
- Record smart π‘
- Document properly π
- Defend lawfully π‘οΈ
- Present professionally π―
π Notes:
- Attach copies of IQ file hashes (SHA256 or MD5) if available.
- Attach screenshots of signal anomalies (optional but helpful).
- Attach basic equipment calibration information (optional if available).
