Trace Residential High-Pitch Squeal

I need a skilled RF-oriented technician to come on-site to my residential address, sweep the area with a portable spectrum analyzer, and pinpoint whatever is generating a persistent high-frequency, high-pitch squeal. The job is straightforward: confirm the exact source, capture the key frequency data, and hand back a concise report that shows your measurements, screenshots or data logs from the analyzer, and a brief explanation of how you isolated the culprit. If you can suggest quick mitigation steps, even better. I’m only considering freelancers who can show solid, hands-on experience doing field spectrum analysis or similar interference hunts, so please highlight that in your bid. Bring your own calibrated portable spectrum analyzer; no software-only solutions will work for this task. Once the source is confirmed I’ll take it from there—just need the expert ears and equipment to get me the facts.
