I’m experiencing suspicious radio-frequency activity that appears to shadow me from place to place. To put the matter to rest—and, if warranted, take legal action—I need a qualified RF engineer to carry out a comprehensive signal analysis, identify any illicit transmitters, and compile hard evidence. Scope of work • Perform an on-site and near-site sweep that covers my home and the immediate surroundings, with attention to possible satellite-related links. • Use professional-grade spectrum analysers, SDR setups, near-field probes, and direction-finding gear to hunt for audio bugs, covert video cameras, and GPS trackers—each is a genuine concern. • Log every anomaly, capture signal characteristics (frequency, modulation, duty cycle, power level, timestamps), and map the location of each source. • Produce a concise, court-ready report that explains methodology, raw data, findings, and your expert conclusion on whether illegal surveillance is occurring. Acceptance criteria 1. A written technical report (PDF) backed by spectrum plots, waterfall screenshots, and GPS-tagged photographs of any discovered device or antenna. 2. A short summary section written in plain English that my attorney can reference directly. 3. All raw measurement files (CSV/IQ recordings) supplied for independent verification. Please indicate the primary tools you intend to deploy and your availability for on-site work, and confirm any relevant certifications or prior bug-sweep experience when you respond.

Hi, I am interested in assisting with your RF investigation project. With a background in RF engineering, wireless communications, signal analysis, and SDR-based diagnostics, I can perform a structured technical assessment to identify, characterize, and document RF emissions using professional measurement methods. For this project, I would use a combination of spectrum analyzers, software-defined radios (SDRs), directional antennas, near-field probes, and RF analysis software to identify signal sources, characterize their frequency, modulation, bandwidth, and signal strength, and distinguish legitimate transmissions from abnormal or unexpected emissions. All measurements would be documented with timestamps, spectrum plots, waterfall captures, and raw data files where applicable. Following the investigation, I will prepare a clear technical report summarizing the methodology, findings, supporting measurements, and conclusions in both technical and plain-language formats. I maintain clear communication throughout the project and will ensure the documentation is organized for independent technical review. I would be happy to discuss the site location, available equipment, and your specific concerns before beginning the investigation. Regards,

Hi there, I am an experienced RF engineer with a background in secure communications and spectrum monitoring. I specialize in identifying non-standard transmissions, covert hardware, and illicit signal shadowing. I understand the sensitivity of your situation and am prepared to provide a professional, court-admissible analysis to establish the facts. Technical Methodology: To detect sophisticated bugs and trackers, I utilize a high-end SDR-based stack (Ettus USRP/HackRF) paired with high-gain directional antennas and near-field probes to isolate localized emissions. My process includes: Spectrum Characterization: Monitoring across the full range (kHz to 6GHz+) to identify anomalies in duty cycles, hopping patterns, or persistent carriers. Source Geolocation: Using triangulation and signal strength attenuation to pinpoint the physical location of any illicit transmitters. Evidence Chain: I will provide comprehensive waterfall plots, CSV measurement logs, and GPS-tagged data to ensure all findings meet legal documentation standards. Deliverables: I will provide a formal report including a "Plain English" executive summary for your legal counsel, ensuring the technical data is actionable. My workflow is strictly disciplined to preserve the integrity of the data for independent verification.

Hi, I can assist with a professional RF signal assessment and documentation process focused on identifying and characterizing detectable radio-frequency activity in your environment. I have experience with RF analysis, SDR-based monitoring, spectrum analysis, signal characterization, and technical documentation. My approach would include a structured RF survey using appropriate tools such as spectrum analyzers, SDR receivers, directional antennas, and near-field probes where applicable. I would document observed signals by frequency, bandwidth, modulation characteristics, signal strength, timing patterns, and other measurable parameters while separating normal RF activity from unusual findings. The final deliverable would include a detailed technical report with measurement methodology, spectrum/waterfall captures, recorded data where available, and a clear summary of findings written in an understandable format. All collected measurement files would be organized for review and verification. I focus on evidence-based analysis and avoid conclusions without measurable supporting data. I can discuss the location, environment, available equipment requirements, and scope of the survey to determine the best approach. Best regards, Ihor

I’d be interested in carrying out a structured, evidence-led RF and technical-surveillance assessment of your property, with the important understanding that the investigation must neither assume nor dismiss surveillance before measurements are reviewed. My approach would combine a calibrated spectrum analyser, wideband SDR, near-field probes, non-linear junction detector where appropriate, thermal and optical inspection, and directional antennas for source localisation, while separately checking for common cellular, Wi-Fi, Bluetooth, GNSS, broadcast, satellite, and household RF sources that can otherwise produce misleading results. Every anomaly would be logged with frequency, bandwidth, modulation, signal strength, duty cycle, timestamps, direction-finding observations, and GPS-referenced photographs, with repeat measurements used to distinguish persistent transmitters from normal environmental activity. I would deliver a clear PDF report containing methodology, instrument settings, spectrum plots, waterfall captures, findings, limitations, and a plain-English legal summary, together with the raw CSV and IQ files for independent review. Any suspected device would be documented and preserved without tampering so that evidence handling remains defensible.
