Band Segmentation (BS) and Radar Detector Rejection (RDR)

Introduction

In the spring of 2013, Escort Incorporated, offered a firmware update to its current line of Redline radar detectors. This update offered two, widely needed features: (a) band segmentation (BS), and (b) radar detector rejection (RDR). The band segmentation feature allows users to select, from 10 filtered settings, a customized band sweep of Ka radar. Traditionally, and still present in many radar detectors, units would scan entire swaths of the Ka band. This posed a combination of issues of related to decreased sensitivity and false alerts for threats in the Ka band. Now, users of a Redlines with the new firmware can program specific frequencies for filtration. The Beltronics STi-R Plus is currently equipped with this feature, and for several years made this detector a preferred pick by customers over the Escort 9500ci. The other update in firmware is the radar detector rejection. Much like the Traffic Safety Rejection (TSR) option, RDR allows the radar detector to negate false alerts from leaked K-band signals by Cobra Inc. detectors.

 

Band Segmentation (BS)

 

What is it?

There is some amount of risk when users segment the Ka band. For example if users come across an old version of the Stalker ATR that operates at 35.2GHz and have setting Ka7 turned-off, then this situation may cause a missed alert. In this case, users should turn-on the Ka7 segment as well as the recommended 2/5/8 segments. The best way to utilize band segmentation is operating the RedLine in Spec display mode (default BS/RDR settings) for a while so they can see the frequencies used in their area and determine the common frequencies used. Users can also use the Geographical Survey to get an idea whats used in their area at RDF Geographical Survey. The key to proper use of band segmentation is understanding what guns are used in the area (MPH 33.8 – Stalker 34.7 – Kustom/Decatur 35.5), and the level of risk users are willing to take for possibly filtering a out-of-tune radar gun. A way to mitigate this risk, if for example a 34.7Ghz gun is seldom used in the town, is by running Ka4 turned-on.

 

High-Threat Frequencies

The most popular radar frequencies used are 34.7 Ka, 35.5 Ka, and 33.8 Ka, so users must ensure these bands are activated. As will be shown in the table below, these frequencies are categorized under settings 2, 5, and 8, respectively.

 

Table of Segments and Recommended Settings

Band Segmentation Listing / Green Recommended
Setting Number Frequency Range (GHz) Default Setting
Ka1 33.392 – 33.704 Off
Ka2 33.704 – 33.896 Off – change to ON
Ka3 33.886 – 34.198 Off
Ka4 34.184 – 34.592 Off
Ka5 34.592 – 34.808 Off – change to ON
Ka6 34.806 – 35.166 Off
Ka7 35.143 – 35.383 Off
Ka8 35.378 – 35.618 Off – Change to ON
Ka9 35.595 – 35.835 Off
Ka10 35.830 – 35.998 Off

Some of the common radar gun frequencies used here in the US are as follows:

MPH Industries Applied Concepts Inc. Kustom Signals Inc. Decatur Electronics McCoy’s Line
33.8 GHz 34.7 GHz 35.5 GHz 35.5 GHz 35.5 GHz

 

Band Segmentation Programming

In the following video, our forum member, “Vortex,” covers the basics of programming the Escort Redline radar detector for band segmentation. The table, presented earlier, illustrates the bands that are most commonly enabled for increasing the radar detection range. This programming applies to the the Escort Redline, Escort 9500ci, Escort Passport, and Beltronics STi-R Plus detectors. NOTE – The video talks about the “Redline XR,” however, there is no such model, but a business on the internet sells a Redline with this title and charges customers a $100 premium for configuring a basic Redline with the same features described in the video.  This video will save you $100.

Radar Detector Rejection (RDR) / Traffic Sensor Rejection (TSR)

Radar Detector Rejection (RDR) is a feature in some Escort and Beltronics radar detectors that filters false alerts in the Ka-band range from Cobra radar detectors. Similarly, Traffic Sensor Rejection (TSR) performs the same functions, except it is found on the Valentine One detectors. Turning RDR off allows you to turn off the filtering of false Ka alerts caused by leaky radar detectors such as Cobras.With the firmware update, RDR is turned-on by default. Beginner users may not initially want to turn-off RDR, however, after some experience, ECCTG recommends users to disable it for improved sensitivity and performance, but with the shortfall of no false filtering. Coupled with the segmentation options listed above, users will have superior range/reactivity and little to no false threat alerts.

This video presented by “Vortex,” our member here on the forum, discusses this feature in detail and how explains how enabling or disabling it can affect the range detection of your radar detector across the K-Band spectrum. In our testing, the Uniden LRD950 was the only detector where TSR did not adversely affect the detection range.
