š” Why Proper TSCM Equipment Matters: A Real Example of Bad Scanning for Targeted Individuals
When you’re being targeted with covert RF signals, you deserve real technical evidence, not guesses.
Unfortunately, even some so-called āprofessional TSCM investigatorsā are not properly equipped ā and today, we’ll show you a real-world example of why noise floor and resolution bandwidth (RBW) matter so much when scanning for covert threats.
šØ Real Example: REI OSCOR with -90 dBm Noise Floor
A recent TSCM report shows spectrum graphs captured using a REI OSCOR Green or OSCOR Blue, a professional sweeping device used in many corporate and government sweeps.
While the OSCOR is an excellent broad sweep tool, it has critical technical limitations when used improperly for serious Targeted Individual investigations:
Factor | What Happened | Why It’s a Problem |
---|---|---|
Noise Floor | About -90 dBm | Real covert signals (implants, passive threats) are often below -100 dBm. A -90 dBm noise floor misses weak signals entirely. |
RBW (Resolution Bandwidth) | Very wide (likely 100 kHz ā 1 MHz) | A wide RBW blurs small signals together, hiding fine covert transmissions inside bigger environmental noise. |
Interpretation | Claimed to detect āP/N junction emissionsā from the human body. | Scientifically incorrect. Standard RF sweepers cannot detect biological junctions through RF emissions. |
šÆ Why Noise Floor Matters
- Every TSCM sweep depends on how sensitive your equipment is.
- -90 dBm might seem low ā but covert transmitters, passive retro-reflectors, or implant backscatter signals often hide at -110 dBm, -120 dBm, or lower.
- If your scanner can’t even see below -90 dBm, you are blind to weak attacks.
Professional SIGINT and TSCM investigations for covert threats typically use:
- Ultra-low noise floor analyzers (-150 dBm or lower)
- Narrow RBW settings (<300 Hz) to separate overlapping weak signals
- Long dwell times (slow, careful sweeps)
A fast sweep like the one done here misses fine signals completely.
š Why RBW (Resolution Bandwidth) Matters
- RBW controls how finely the analyzer separates frequencies.
- A wide RBW (like 100 kHz or 1 MHz) averages together signals ā if a covert beacon is hiding inside a loud broadcast, youāll never see it.
- For detecting covert emissions:
- You want RBW of 10 kHz or smaller.
- This allows you to spot narrowband signals that would otherwise be masked by larger noise.
š¢ The Truth: Real TSCM Requires Real Equipment
Real TSCM Sweep Needs | This Example |
---|---|
Noise Floor < -150 dBm | -90 dBm only |
RBW < 300 Hz | 100 kHz+ estimated |
Long, careful sweep | Fast baseline sweep only |
Proper source identification | Misinterpretation of biological P/N junctions |
š” Frequency Classifications
Frequency | Service Type | Typical Use | Notes |
---|---|---|---|
479 MHz | Land Mobile / Auxiliary Broadcast Services | TV studio-transmitter links (STL), remote broadcast links, and low-power devices | – Falls inside the 450ā470 MHz range (UHF T-band) used for licensed land mobile and some auxiliary broadcast services. – Specifically, 470ā512 MHz is called the “UHF-TV Sharing Band” where TV broadcast and land mobile users share spectrum. – Some Part 74 auxiliary operations (TV studio links, wireless microphones) may use it. – Also eligible for unlicensed low power use (if <50mW ERP under FCC Part 15), which is what the TSCM report vaguely mentioned. |
887 MHz | Cellular Band (Extended) | Sprint (legacy), small carriers, sometimes private LTE, paging systems | – 869ā894 MHz is the original U.S. cellular band. – 880ā890 MHz was traditionally uplink (device to tower). – 887 MHz specifically falls right inside the uplink range. – This is normally carrier-to-tower transmissions, like cellphones. – Could also be pagers, alarms, IoT devices operating through private cellular networks. – Absolutely not a standard implant band ā way too high power and structured for that. |
šÆ What This Means Technically
Claim | Reality |
---|---|
479 MHz signal from “P/N junction scanning” | Highly unlikely. Far more likely a nearby low-power auxiliary broadcast device, walkie-talkie, wireless microphone, or even background environmental noise. |
887 MHz signal from “P/N junction scanning” | Extremely unlikely. This is in the cellular uplink range ā meaning most likely background traffic from a nearby cellphone, tower, or LTE device. It is normal to see signals here even in a clean sweep. |
ā” Critical Analysis
- 479 MHz is used by licensed low-power broadcast and auxiliary systems, not mysterious hidden implants.
- 887 MHz is almost certainly cellular noise ā impossible to separate body emissions from a busy cellular environment without extremely specialized tools (even then, very hard).
Bottom line:
Both frequencies are normal for city/suburban RF environments.
Neither indicates biological emission or hidden P/N junction activity.
š Final Summary
Frequency | Legitimate Use | Likelihood This Is a Covert Threat |
---|---|---|
479 MHz | Licensed auxiliary (wireless mics, remote cameras) + some unlicensed low-power | Very low |
887 MHz | Cellular device uplink (normal phone traffic) | Almost zero |
š¬ Final Thoughts
When your freedom, health, and privacy are at stake, you need the right tools.
Even a professional with a good reputation can fail you if they aren’t using ultra-sensitive equipment or don’t properly understand RF physics.
If your TSCM sweep:
- Shows a high noise floor
- Doesn’t use tight RBW
- Jumps to conclusions about “biological emissions” from standard RF sweeps
Then the sweep is not valid.
š Always demand high-sensitivity, fine resolution, and scientific validation ā not assumptions ā when your life depends on it.
