Subject: Cease Fraudulent Claims Regarding the “Cyber Shield” Device – Technical and Legal Violations Identified

---

Dear Mr. Ruble,

I am writing you directly regarding your continued marketing and sale of the so-called “Cyber Shield” device, which you are reportedly charging victims upwards of $2,500 for. After a comprehensive technical review and independent replication attempt of your claimed setup, I am formally notifying you that:

Your product is both scientifically fraudulent and potentially illegal under U.S. federal law.

🚨 Your Technical Claims Are False

You claim that your device:

• Uses ADF4351 RF synthesizers
• Is controlled by a microcontroller (unspecified, likely Arduino- or STM32-class)
• “Heterodynes” targeting signals into the 5–40 Hz brainwave range
• Doesn’t need to detect frequencies to interfere with them

Each of these claims is demonstrably false:

• The ADF4351 operates in the 35 MHz to 4.4 GHz range — it cannot generate, interact with, or heterodyne signals into the 5–40 Hz domain.
• The RBW (resolution bandwidth) of the ADF4351 is around 300 kHz, making it millions of times too wide to operate at brainwave resolution.
• No detection, signal classification, or IQ data analysis is performed — which violates the basic principles of RF countermeasure design.

I personally reconstructed your device using identical hardware and verified it does absolutely nothing related to jamming, interference, or brainwave-level signal shaping.

⚖️ If It Emits Anything, It’s a Felony

According to FCC rules:

“The use or marketing of a device designed to block, jam, or interfere with authorized radio communications is a violation of federal law…”

If your device emits random RF noise, you are operating an unauthorized jammer, which under U.S. law can carry:

• Civil fines up to $112,500 per violation
• Criminal charges and imprisonment
• Product seizures and FTC action for fraudulent claims

If the device does nothing: It’s a scam.
If it transmits RF: It’s a federal crime.
Either way: It’s not protection — it’s liability.

❌ False Testimonials and Manipulation

Your operation is further propped up by:

• Unverifiable testimonials from anonymous individuals
• Emotionally charged stories that repeat your unscientific language
• No data, no spectrum evidence, no IQ samples — just hearsay and marketing

This is classic social engineering of a vulnerable population. It is manipulative, unethical, and likely prosecutable under consumer protection law.

🧠 You’re Hurting the TI Community

This scam:

• Drains life savings from victims
• Diverts attention from real evidence and engineering
• Discredits legitimate RF investigations
• Opens buyers to legal danger if they accidentally interfere with radio services

And most of all, it emboldens skeptics and disinformation agents who label TIs as delusional — because grifts like yours give them all the ammunition they need.

🧾 Final Notice & Challenge

You are hereby requested to:

1. Immediately cease all marketing and sale of the Cyber Shield device
2. Publicly retract the claim that it can heterodyne signals or block V2K
3. Submit to a recorded, technically moderated public review where:
   • You demonstrate the device’s spectrum output
   • You provide IQ data or emission data
   • You explain your signal chain and interference method

Failure to comply will result in:

• A public technical report and breakdown distributed to every major TI platform
• A submission to the FCC and FTC with your name, screenshots, and hardware layout
• Legal pressure from those affected by your fraud

Sincerely,
