MESA’s New RF Jammer/Interference Detection

A firmware update is available for the MESA spectrum analyzer that includes a new Jamming/Interference Detection feature in the Mobile Bands mode.  In our last Newsletter, we discussed jammers and the role TSCM plays in the detection and location of RF jammers.

Criminal use of RF jammers continues to trouble law enforcement, military, corporate and private security and public safety.  The presence of an illicit jamming signal is typically an indication of some other illegal activity or security threat.  RF security is one of the main concerns of TSCM, therefore it is important to know when jammers or other forms of interference are present.

The MESA’s Jammer/Interference Detection feature is enabled by default and generates alerts when an increased density of RF energy in a frequency band is detected.

The image above shows an example of an active jammer detected in Band 2 (835-850 MHz). A Jammer Detection might appear in a single band or multiple bands depending on the frequencies being targeted. Bands 4 and 6 in the image above indicate a jammer or interference was detected in the past but is no longer active in these bands.  Because the MESA Mobile Bands are customizable, the user can create a detection band at any frequency up to 6GHz. Double-clicking on a Band displays a spectrum view of that Band. Below is a screenshot of a zoomed-in view of a jamming signal from Mobile Band 2. Notice the Mode icon outlined in blue still shows Mobile Bands while displaying the spectrum view. Clicking on the magnifying glass icon   will return to the Mobile Bands screen.
MESA detects jammer

A Signal Overload can also occur when the receiver is saturated with strong RF energy from a jammer or interference and will show red throughout all of the bands. When this happens, moving away from the transmitter or adjusting the Attenuation may help reduce the overload status.

The Jammer/Interference feature provides configuration adjustments for power, sensitivity and alerts settings. The Band titles can be customized as well as the frequency spans of the Bands.

Jammer Detector Log
Jammer/Interference Detection logs activity and can be viewed and saved to a USB storage device.  The time, date, frequency and power history of the interference is recorded.

The Lock option provides a way to prevent the Jammer Detection feature or any of the settings from being changed or disabled.  Operations can still be monitored in a dimmed display but settings can’t be changed unless unlocked with the user-defined pin.

The MESA’s Jammer Detection feature is one example of REI’s continuous product improvement.  The free MESA firmware update (version 1.1.9) that includes the Jammer/Interference Detection feature is available to download from the REI website along with update instructions.

Non-Alerting TSCM, a Common Mistake

We often get asked about “non-alerting” ways to keep an eavesdropper from knowing the security products and technical surveillance countermeasure equipment (TSCM) being used.  In Sun Szu’s Art of War, he describes the need for secrecy when making tactical decisions.

Sun Szu’s Art of War, Chapter 6

“O divine art of subtlety and secrecy! Through you we learn to be invisible, through you inaudible; and hence we can hold the enemy‘s fate in our hands…
In making tactical dispositions, the highest pitch you can attain is to conceal them; conceal your dispositions, and you will be safe from the prying of the subtlest spies, from the machinations of the wisest brains.”

However, the question of being “non-alerting” is usually asked from the perspective of how security measures are performed, and the process for purchasing products and services is often missed as one of the most “alerting” actions.

Public tenders for acquiring intelligence security products can expose existing security weaknesses while also advertising the types of countermeasures being purchased. Public tenders are typically intended to promote competition, secure the best price, provide fair opportunity for all, and make the tender process transparent.  But with intelligence products, an argument can be made that full transparency may not be the best strategy.  There’s a point where transparency can be synonymous with exposure.  All security products have limitations.  So if you know the security products being used, you can also figure out its vulnerabilities.

When playing cards, the dealer usually slides your cards face down so other players can’t see them.  And the cards are usually kept face down or held up close, to keep other players from peaking at your hand. Unless you want to lose, you don’t lay them on the table for everyone to see.  Purchasing security equipment should, as much as possible, be the same. Federal government and law enforcement agencies around the world use closed processes to purchase TSCM equipment.

There are other reasons public tenders can produce undesirable results including:

  • Slow process
  • Confusion about technical requirements or the specifications are too broad
  • Suppliers of inferior products may claim compliance when in fact they do not meet required specifications or needs
  • Process puts communication barriers between provider and customer
  • Difficult to know when cheaper, poor quality materials/labor are used
  • After sales support, repairs, and training are often not accurately accounted for in procurement
  • Post award changes can be very costly

Too often we hear stories from people who find the perfect product solution to a problem, but end up with a lesser or ineffective product as a result of the public tender process. Usually, because the person processing the tender weighed price over feature and performance criteria, or didn’t fully understand or specifically define the desired solution.

Sole source justification is one way of protecting intelligence product purchases from public exposure and to clearly define the purpose and application of the procurement.  Sole Source definition according to Office of Justice Programs, U.S. Department of Justice Sole Source Justification Fact Sheet:

“Procurements by noncompetitive proposals, referred to as sole source procurement, is procurement through solicitation of a proposal from only one source. Recipients may conduct competitive (‘sole source’) procurement through solicitation of proposals from only one source when one or more of the following circumstances apply:

  • The item is available from only one source
  • The public exigency or emergency for the requirement will not permit a delay resulting from competitive solicitation
  • Competition is determined inadequate after solicitation of a number of sources”

Because of the sensitive nature of security products and the unique technical requirements, REI recommends considering closed procurement methods where appropriate.  This not only ensures that the proper equipment is purchased, but also that the security capability is not exposed, which can lead to an even greater security risk.

When you make efforts to increase security capabilities, be sure not to disclose them, either during security activities or the procurement process.

REI does not propose sidestepping good contracting practices, or using sole source justification to avoid competition.  Government and commercial procurement agencies can, and should verify manufacturer pricing to ensure it is fair, reasonable and equitable, and free from conflict of interest.

GPS Tracking Devices and the ANDRE®

GPS tracking devices leave a minefield of malicious threat opportunities. This can include the endangerment of military personnel by having their location revealed, the discovery of secret business meetings, or someone being tracked by an abusive partner. GPS tracking can expose anyone to unwanted surveillance.

A GPS tracker receives signals transmitted by satellite to determine its location on earth. A tracker usually receives location signals from at least four satellites, while additional satellites help refine and improve location data. With the boom of mobile devices, GPS has improved to incorporate the use of cell tower, Wi-Fi and Bluetooth information to help pinpoint locations. Location accuracy depends on the type of GPS device being used and the location data it can receive.

Three Types of GPS Devices

GPS tracking devices come in three types: data logging, data pushing and data-pulling devices. Data Logging devices only use satellite signals and the information is stored on the tracker. This type of device must be retrieved to access the information. Data Pushing trackers receive satellite information and then continuously push the information to a cellular network. The data gets transferred to a server and then to the internet, where location data can be viewed through an app or browser. Data-pulling devices receive location information and broadcast this information to the person doing the tracking at set intervals, when a predefined parameter has been met, or at the user’s request. Parameters may include geofencing, movement, speed, when a car is turned on, etc. For example, the device may be programmed to send a notification when the vehicle arrives at specific location, like an office, stadium, house, etc.

Adding Technical Surveillance Counter-Measures (TSCM) to the Mix

TSCM can help protect privacy and information from GPS threats. The ANDRE Broadband Receiver is good for detecting GPS pushing and pulling trackers. The ANDRE can detect the RF transmission from the tracker to the cellular tower, even as fast as 1/1000th of a second. Because the ANDRE is a broadband receiver, it displays the amplitude of the strongest RF signal; regardless where in the 6GHz (or 12GHz with the Down Converting antenna) it occurs, which will be mostly in the cell phone band for trackers. This ensures almost 100% probability of intercept (POI).

Practical Application

Typical search procedures and methods for working with the ANDRE to detect GPS devices include:

  • Set up the ANDRE Deluxe and whip antenna in the center of the vehicle
  • Activate the Data Logging feature (ANDRE Deluxe)
  • Drive the vehicle to check for geofencing, speed, interval, Bluetooth and/or Wi-Fi perimeter triggers
  • You may also choose to leave the ANDRE in the vehicle for a period of time (up to 250 hours) to look for transmit patterns
  • Turn on the “Chart Audio/Live Audio” feature on the ANDRE to hear distinctive pings from the transmission of GPS data to a cellular tower
  • Block off all incoming cellular tower signals to the GPS tracker. Once cellular frequencies are available again the GPS will quickly have a more active connection “frenzy” while re-establishing communication with a tower. This may give the ANDRE a stronger signal to detect.
    • Eliminating signal activity may be possible by isolating the vehicle from cell towers using natural barriers or by using a sterile RF environment.
    • Jamming the surrounding signals may also be possible; however the use of jammers is highly regulated. Know the responsibility you have using a jammer and the legal/regulatory implications.

As good as the ANDRE® is, it doesn’t replace the necessity for a physical search. The longer an enemy has to install an illicit tracker, the more sophisticated the installation can be – making the TSCM search more difficult. GPS trackers require either a physical retrieval or a transmission of RF energy to view target location data. For a tracker that requires retrieval, or transmits only upon request, nothing replaces a thorough physical search of the vehicle.  For other transmitting GPS devices the ANDRE Deluxe provides the best chance of detecting unknown GPS trackers.

Online Seminar Schedule Through June 2022

When you’re in a Jam

RF Jammers are used to block or interfere with the physical transmission and reception of wireless communications.  In most cases, they work by generating RF energy to overwhelm or confuse RF transmissions.  They can deny service indiscriminately or they can target specific classes of transmission (GPS, Wi-Fi, Bluetooth, cell phone, etc.).

Jamming technology has not been historically considered in TSCM applications, but the fact that jammers may interfere and disrupt RF transmissions means the necessity to investigate for jammers will undoubtedly increase.

New technologies and the Internet of Things (IoT) are being developed all the time that use wireless communications and so are opportunities to interfere, disrupt, and manipulate them.  Causing denial of service can be disruptive and, possibly, extremely dangerous.

A quick list of wireless applications that can be affected shows just how harmful illegal or illicit jamming can be:

  • GPS (location, navigation, tracking, mapping, timing)
  • Cell phones (emergency 911 calls)
  • Bluetooth devices
  • Key-fob/car locks
  • Wi-Fi communications
  • RF equipment+
  • Satellites
  • Security equipment
  • Radio transmissions
  • Industrial controls
  • Home automation
  • Fleet management
  • Drones

Despite the illegality of jammers (in most countries), they are commercially available, inexpensive, and used privately, often marketed as security devices, but criminals use them to conceal illegal operations, disrupt law enforcement or first responder communications, disrupt surveillance efforts by law enforcement, block or disrupt wireless security equipment, block GPS trackers, even parole ankle bracelets.  Types of jammers include 5G/4G/LoJack/XM, GSM/GPS, Walkie-Talkie, Wi-Fi, Bluetooth, and more.

Can Jammers Be Defeated?

There are only a few ways to practically defeat a jammer:

  1. Move out of its range:
    • Distance – getting out of range of the jamming signal. Without knowing the location of the jammer, this will be difficult.
    • Frequency -searching for quiet channel or possibly selecting a different frequency modulation scheme.
    • Amplitude – using power management techniques, increase the transmit amplitude for outbound transmissions (attempt to overcome the jammer interference)
  2. Detect, locate and disable the jammer source.

This is where TSCM skills come into play.  Jammers, by design, transmit strong RF signals, meaning the transmit signal can be detected with a spectrum analyzer.  The right spectrum analyzer for detecting and possibly locating an RF jammer should include:

Portability:   The spectrum analyzer must be portable and mobile so it can sweep and rapidly analyze energy in different areas.

Frequency Range:  The spectrum analyzer needs to cover a wide frequency span.  A signal strength indicator alone, like most basic RF detectors have doesn’t provide the information needed to differentiate a jamming signal from other RF activity. Some jammers flood multiple frequency spans simultaneously while others target specific spans, so it’s important to have a spectrum analyzer that shows the scope of the jamming signal.

Analysis Capability:  A spectrum analyzer that can isolate jamming signals into frequency bands (cell phone, Wi-Fi, Bluetooth) provides an excellent method for quickly identifying targeted devices.  Spectrum view, Waterfall and Persistence display also provide additional perspective on the signal’s activity over time.

These are just a few things to look for in a spectrum analyzer to aid in signal jammer search and detection. REI will soon be introducing new features in the MESA Mobile Bands function to help detect and locate RF jammers.  This feature will be available as a free firmware update on REI’s website and will be in new shipments beginning in July.  Watch for more information in the next edition of the REI Newsletter.

Non-Linear Junction Detectors (NLJDs) have been used for decades to detect and locate hidden electronics, and REI’s ORION was among the earliest brands developed.  A number of NLJD manufacturers have since come and gone but ORION has remained, adapted to technology changes, and today is by all standards considered the leading NLJD internationally, and not because it outlived the others.  The ORION has many advanced features that make it stand out from the rest.

Operational Features

Advanced Transmit Signal

The ORION antenna head radiates a low power 1.25 MHz-wide OFDM spread spectrum RF signal. Shown here is a screen shot from an OSCOR spectrum analyzer that demonstrates the difference between ORION’s wide digital spread spectrum signal compared to a narrow analog TX signal of a typical NLJD. The wider Digital Spread Spectrum signal provides higher probability of detection using less peak power.

Touchscreen Display and Antenna Head Display

ORION HX models are the only NLJDs with a touchscreen display delivering specialized data graphs that can be screen captured and saved to micro-SD for reporting. Display graphs include:

  • Frequency Adjust Screen – displays a graph of the ambient RF activity in the TX, 2nd and 3rd harmonic frequencies. This is necessary for selecting quiet channels to prevent interference in the transmit and harmonic frequencies
  • Spectrogram View – provides a spectral view of the 2nd and 3rd harmonic receivers
  • Histogram Display – a graph that displays a history of transmit power and harmonic activity over time (see below). No other NLJD can deliver this kind of data.

All tools, settings and operations are controlled through the touchscreen menus. ORION HX also has an antenna head display for line of site monitoring of the target area.

Frequency Avoidance

The ORION is the only NLJD in the world with a built in spectrum analysis view for transmit, and both 2nd and 3rd harmonic frequencies. This ensures the ability to operate on a clear frequency band and eliminate interference and false alarms in a dense RF environment. In this screen shot taken in Sao Paulo, Brazil; there was clearly RF interference in each band, but the unit was easily tuned to a clear channel for reliable operation. Other competitive products claim frequency agility, but no other NLJD in the world has 60+ channels in which to find a quiet frequency and avoid interference.

The ORION also provides several transmit frequency selection modes including Auto (automatically sweeps for a quiet channel) and Manual (user selects the TX frequency). Select models also include a Sweep mode (continually sweeps sequentially through channels), and Hop mode (randomly hops through channels).

The ORION digitally modulates the transmit signal with OFDM technology that correlates the 2nd and 3rd harmonic when received by the ORION. This significantly increases detection gain and helps prevent false detections.

Advanced Transceiver Technology

The ORION has unparalleled receiver sensitivity: -140 dBm

DSP Gain (Patented)

Another feature unique to the ORION is the adjustable DSP (Digital Signal Processing) Gain feature. This setting configures the level of DSP integration used to process the received signals. Sensitivity increases as the DSP Gain is increased from Low to High.


ORION provides 3 types of alerts when RX signals exceed adjustable thresholds.  Alerts are important for discreet sweeping and for sweep efficiency. Alerts include Audio (headphone or speaker), Visual (antenna and touchscreen displays), and Haptic (handle vibration). In most NLJDs, audio and/or visual may be available, but not all 3.

Automatic Power Control (Patented)

Transmit power level on the ORION can be changed manually or automatically.  In the Auto transmit power mode, the transmit power will automatically reduce whenever the receiver becomes saturated. In Manual, the transmit power remains at the same level until it is manually changed.


Antenna Head Design

The ORION 2.4 has a smaller antenna head that transmits a shorter wave length signal, which is better for smaller, modern electronics.  The ORION 900’s larger wavelength antenna is better for larger, older electronics, and it is also better for penetrating denser materials (bricks, walls, etc.). The ORION HX Deluxe includes both interchangeable antenna heads in a single package to provide better detection sensitivity throughout changing environments.

The ORION’s unique Patented spiral antenna is circularly polarized to transmit and receive, removing the risk of missing a threat due to incorrect antenna polarization, improving reliability and sweep efficiency.

The ORION is designed for harsh environments:

  • Water resistant
  • Protected from dust ingress
  • Operating temperatures -10° to 60°C / 14° to 140°F



ORION is the only NLJD available that has FCC AND CE mark models, which is very important to ensure safe operation and legal use around the world. No other NLJD meets the regulatory standards of the ORION.

There are many intangible benefits that come with the ORION — in-house manufacturing for reliable quality control, training, experienced sales and product support, just to name a few.  At the end of the day, it’s important to have the right NLJD that provides the highest probability for finding electronics.

REI has released two new free online seminars:

When you take the best features of a portable, handheld broadband RF detector (size, portability, utility) and combine them with the analysis capability of a spectrum analyzer, you get the MESA® – Mobility Enhanced Spectrum Analyzer. The MESA® is a compact, full-featured portable spectrum analyzer with physical search capability similar to a broadband receiver.

The first thing you may notice about the MESA® is how easy it is to navigate. Once you get a feel for the menus, icons, buttons and the main screen controls on the 7” capacitive touch screen, it may seem like you have it all figured out, but really, you’ve only begun to scratch the surface. Beneath the user friendly display is a powerful palette of tools and functions to help identify and locate signals.

MESA Deluxe Antennas/ProbesAntennas
MESA® is available in a Basic and Deluxe package (see the Accessories comparison chart). The MESA® Deluxe includes six RF antennas. The Fixed Dipole and Whip Antenna, are uniquely designed hybrid antennas that include a circular dipole for a higher frequency, and a longer mass antenna for low-frequency signals. The Down Converter antenna is a directional antenna with a frequency range from 500MHz to 12GHz. Other antennas include a Locator Probe, VLF probe, and low-frequency directional antenna. The QMA antenna input allows for non-REI antennas to be connected.

MESA®  also has a Multi-Carrier Probe (carrier current), Ultrasonic, IR/Visible light, Audio Transformer and Audio Leakage probe. MESA® automatically recognizes REI antennas and probes when connected and adjusts the frequency display.

MESA Spectrum AnalysisOperation Modes – Spectrum Analysis
MESA®, like the OSCOR®, is a portable swept-tuned super heterodyne spectrum analyzer that sweeps to 6GHz (12GHz with the Down Converter antenna included in the Deluxe model), at a speed of >200GHz per second at 312.5 kHz resolution bandwidth.

The Resolution Bandwidth (RBW) auto-adjusts depending on the frequency span.
• The narrower the span the finer the resolution bandwidth
• The wider the span, the higher the sweep speed

MESA® displays a full range of frequency data including span, start and stop frequencies, dB, RBW, Peak/Average Trace, Persistence Trace (below 200MHz spans), raster waterfall, RSSI, Alerts, and signal lists.

A new patented Cached Peak feature, preserves and displays 312.5kHz and 39kHz resolution Cached Peak traces as the span is zoomed in to higher resolutions, enabling peaks obtained at previous resolution bandwidths to be seen.

SmartBars™ – Mobile Bands – WiFi/Bluetooth®
SmartBars™ is a new patented mode that quickly detects and locates RF energy by displaying a bar graph of new signals, or increased RF energy, compared to a reference trace from outside the target sweep area. SmartBars™ offers a Fast Scan and a Signal Resolution scan which creates a signal list of signals that exceed the user-defined threshold.

Watch this video for an overview of how SmartBars™ works.

Additional display modes include Mobile Bands displaying RF energy levels for multiple RF Bands (i.e. WiFi, GSM, etc.) on one screen. Each Band is customizable to user-defined spans. This mode is excellent for quickly searching for RF energy in specific spans.

WiFi and Bluetooth® modes display nearby WiFi access points and Bluetooth® devices, relative signal strength, and links to the Spectrum View to view it in live frequency trace mode.

The MESA® is a completely new product that complements REI’s existing RF products – ANDRE® and OSCOR®. With the complexity and sophistication of new threats, multiple RF detection tools are required. Here are some of MESA’S benefits:

• Easy to use spectrum analyzer in a handheld package with touch screen controls
• Portable: 5 x 8 x 2 inches; (12.7cm x 20.3cm x 5.08cm), 1.08kg
• Sweep speed:  >200GHz/second at 312.5kHz resolution; 30GHz/second at 39kHz resolution
• Quiet, flat noise floor with no internal spurious signals
• Quick to deploy and easy to use and walk around with, for fast effective site surveys.
• Patented SmartBars™ function to quickly and easily identify new signals using inside to outside comparison.

REI Online SeminarsWhen COVID brought travel to a halt in early 2020, REI had to cancel many of its training courses, but customer demand for product and TSCM information never diminished. Since change and adaptation became the theme for 2020, REI instructors began searching for different ways to stay connected and at least try to satisfy some of the appetite for information.

REI customer feedback has always concluded that virtual training will never achieve the standard of in-person training for a number of reasons (hands-on access to equipment, live exercises, personal instruction, and networking). Under the present circumstances; however, virtual webinars can certainly provide value in the absence of in-person training.

REI instructors developed a series of free online Zoom Seminars to provide an overview of products and popular TSCM topics which includes ANDRE; OSCOR; TALAN; ORION; GPS Tracking; Basic Telephony; Introduction to VoIP, with more to come. Each seminar is approximately 1 hour long with Q&A at the end. The format is informal and interaction is encouraged. Capacity is limited to ensure optimal participation, so early registration is recommended.

In-person training courses have resumed, but REI plans to continue offering the online seminars. Schedule and registration information for online seminars and REI Training courses are available through the links below.

The REI Training Center recently added a new Level 2 course for REI’s newest product: MESA® – Mobility Enhanced Spectrum Analyzer.

The 5-day MESA® course will review radio frequency energy fundamentals. This module will further explore the basic characteristics of radio frequency (RF) energy and how it behaves in a normal environment. The purpose of this segment will be to build on the student’s knowledge of RF energy as it relates to spectrum analyzers. 

Trainees will be introduced to the MESA by examining its technical specifications, operational features and function compared to other REI RF products – ANDRE and OSCOR. Modes and features to be examined in hands-on exercises include Spectrum Mode, the patented SmartBars™Mobile BandsWi-Fi and Bluetooth® 

The Countermeasures Core Concepts course is a prerequisite to the MESA Course.  Schedule and registration for the MESA® training course is available here.

7 Ways to Protect Your Equipment from Electrostatic Discharge (ESD).

The weather is changing and cooler temperatures mean short days, cozy sweaters, and static electricity. Colder, drier air outside causes us to turn on heat indoors further lowering humidity, which adds to the conditions that promote static electricity.  Today’s electronic components and assemblies tend to be smaller more efficient, and also more delicate and sensitive to ESD and can be affected by even the smallest unseen, unfelt electrical charge. ESD can cause erratic operation, shortened electronic life expectancy, or catastrophic failure.

At REI our production teams take extra precautions to prevent static electricity, and here are a few tips to keep your products functioning properly.

  1. Review the product user manual.
  2. Prep your work area – use a grounding work surface or mat when possible.
  3. Check the humidity levels of the environment you’re sweeping in, take extra ESD precautions when working in a dry environment.
  4. Transport and store the equipment in the original manufacturer’s case to prevent accidental ESD events.
  5. To discharge built up ESD on your person, touch a piece of metal before handling any electronic equipment.
  6. Practice social distancing – keep charged materials about a foot from your devices. Be aware of how close you’re keeping plastic, foam, scotch tape, and other materials that can build up a charge.
  7. Try not to overdrive your equipment inputs.

Taking precautions for ESD can save time in your sweeps and money.
