How to Set Up & Configure the Radenso RC M

Radenso RC M radar detectorThe Radenso RC M is an excellent custom installed radar detector with great performance, false alert filtering, low powered radar detection, and ALP integration.

The Radenso RC M manual does a great job going over the radar detector and so in this tutorial, we’ll go over things in a bit more detail and help you get the RC M set up for where you drive.

Radenso RC M’s Settings & Menu Options

The RC M is highly customizable, even more-so than most other detectors, and there’s a lot of options available here.

If you’re running front and rear radar antennas for arrows, the RC M gives you independent controls for both antennas. Usually you’ll want to configure the two antennas identically, but it can be nice to operate them independently. For example, in Edmonton you can enable MRCD for the front antenna and disable it for the rear. This way you’ll get sufficient warning as you approach, but limit the excessively long rear alerts you’ll get as they continue shooting you from behind despite you being long past the kill zone.

Now that said, Radenso’s default settings (marked with a *star) do a great job of giving you a quiet detector out of the box. There’s very few settings that I even bother changing. Let’s run through all of them.

Front Radar

Enable detection of your front radar detector antenna.

  • *On
  • Off

Rear Radar

If you have a second rear antenna to give you arrows, enable this option.

  • *On
  • Off

Driving Mode

This allows you to adjust the sensitivity of the RC M’s radar detection. You can adjust X, K, and Ka band sensitivity individually (in an upcoming menu option). The driving modes allow you to choose if and when the detector drops to reduced sensitivity (ie. at lower speeds around town to help cut down on false alerts).

  • Highway: Full sensitivity at all times
  • City: Reduced sensitivity at all times
  • *Auto City: Automatically switches between full sensitivity at higher speeds and reduced sensitivity at lower speeds

Auto City Speed Limit

The first number is for low speed muting. X and K band signals below this speed will be automatically muted.

The second number is the speed threshold for when the sensitivity changes. Below this speed, Auto City mode reduces the detector sensitivity. Above this speed, it runs at full sensitivity. (Default: 30 / 60)

  • 0-55 mph / 35-130 mph

City Level (Front Antenna)

Individually adjust the sensitivity of X, K, and Ka band for the front antenna.

This number adjusts signal attenuation. You can think of it as how strong the signal needs to get (1-9) before you get an alert.

Lower numbers mean less filtering and more sensitivity/range. Higher numbers mean more filtering and less range. Set it to “0” for maximum performance.

  • X 4, K 2, Ka 0

City Level (Rear Antenna)

Same as above, just for the rear antenna.

  • X 4, K 2, Ka 0

F-X Band (Front Antenna – X Band)

Enable X band detection for the front antenna.

X band has been phased out of most of the US. It is actively in use in OH, NJ, and a few rural places here and there. Most people are safe disabling this to avoid X band false alerts.

  • *On
  • Off

F-K Band (Front Antenna – K Band)

This allows you to both enable/disable K band detection and to adjust how wide the detector scans across K band. You can scan all of K band or cut off the lower and upper ends to help cut back false alerts if there’s not a ton of low/high frequency K band in your area.

Low is a good option if you have a fair amount of K band in your area and want a good balance of filtering and range. High is the best option if you don’t face a ton of K band and you want the quietest detector possible.

  • Wide: 23.950 – 24.250 GHz (24.100 GHz ± 150 MHz)
  • *Narrow: 24.010 – 24.190 GHz (24.100 GHz ± 90 MHz)
  • Off: Disable K band detection

F-TS Rej

Traffic sensor rejection allows you to filter out many false alerts on K band at the expense of ultimate range. High gives you the most filtering, Low in the middle, and Off the least.

If you’re running it on Low and are seeing fixed traffic sensors along the highway causing K band falses on your RC M, switch this to High.

  • Off
  • Low
  • *High

F-Ka Band

This allows you to enable/disable Ka band detection on the front antenna as well as adjust how band segmentation works.

Ka Narrow gives you the best performance and control over which frequencies are scanned while Ka Wide scans everything and helps cover potentially out of tune guns.

  • Off: Ka band detection disabled
  • Wide: 33.4 GHz – 36.0 GHz
  • *Narrow: Enables individual Ka segment options. Each segment is ± 120 MHz.
    • F-Ka 33.8
    • F-Ka 34.3 
    • F-Ka 34.7 
    • F-Ka 35.5 

F-Ka Filter

Filters out false alerts on Ka band.

You can try running Normal and then if you see a bunch of false alerts on Ka band, you can crank it up to High.

  • Off
  • Normal
  • *High

F-Ka POP

Enables Ka band POP radar detection. POP is an infrequently used form of radar available in certain MPH brand radar guns. It is designed to allow an officer to preview a vehicle’s speed without alerting radar detectors by using a super quick burst of radar that’s too quick for radar detectors to pick up on. This setting enables POP radar detection.

It’s recommended to leave this feature off though since POP isn’t used much at all, it’s not legal to issue tickets without using traditional radar too, and it generally causes both reduced performance and false POP alerts.

  • *On
  • Off

F-Laser

Enables laser detection using the laser sensor built-in to the radar detector head. This is separate and completely independent from the laser jammer controls if you’re running it paired with an optional laser jammer.

  • *On
  • Off

F-MRCT

Enable detection for MultaRadar CT.

This is a low powered photo radar unit that’s used in places like Chicago and NYC. If you enable MRCT detection, you will see quite a few false MRCT alerts from nearby vehicles with blind spot monitoring (BSM) systems. Since MRCT is generally only in fixed redlight that you can get alerted to via the GPS database anyway, it’s generally recommended to leave this off and rely on GPS alerts if you have these in your area.

  • *Off
  • Wide
  • Narrow

F-MRCD

Enable detection for MultaRadar CD.

The MRCD is also a low powered photo radar gun. It’s in use in places like Alberta, Quebec, NYC, Maryland, & Washington D.C. MRCD systems can be fixed or mobile so you can’t rely on GPS for these. MRCD falses are also less common than MRCT, but they still do happen from certain Ford, Nissan, Subaru, Toyota, and Lexus vehicles so you should only enable this option if you have MRCD in your area. If you need MRCD detection, the Radenso RC M is an excellent choice. It’s the go-to solution for people who face MRCD regularly.

Narrow is generally what people run for the MRCD to help cut down on false alerts.

  • *Off
  • Wide
  • Narrow

F-Gatso

This is a low powered mobile photo radar system used in Iowa.

  • On
  • *Off

F-MR Filter

MultaRadar and Gatso false alert filter.

  • Off
  • Low
  • *High

R-X Band (Rear Antenna – X Band)

Moving on we have all the same radar detection options, but for the rear antenna. This option allows you to disable X band detection behind.

  • *On
  • Off

R-K Band (Rear Antenna – K Band)

Configure K band detection for the rear radar antenna.

  • Wide: 23.950 – 24.250 GHz (24.100 GHz ± 150 MHz)
  • *Narrow: 24.010 – 24.190 GHz (24.100 GHz ± 90 MHz)
  • Off: Disable K band detection

R-TS Reject

Traffic Sensor Rejection / K band false alert filtering behind.

  • Off
  • Low
  • *High

R-Ka Band

Rear Ka band detection.

  • Off: Ka band detection disabled
  • Wide: 33.4 GHz – 36.0 GHz
  • *Narrow: Enables individual Ka segment options. Each segment is ± 120 MHz.
    • F-Ka 33.8
    • F-Ka 34.3 
    • F-Ka 34.7 
    • F-Ka 35.5 

R-Ka POP

Rear Ka band POP detection.

  • *On
  • Off

R-Laser

Laser detection behind using the rear radar detector antenna.

  • *On
  • Off

R-MRCT

Rear MRCT photo radar detection.

  • *Off
  • Wide
  • Narrow

R-MRCD

Rear MRCD detection. This is often recommended to be run disabled. In Edmonton, Canada where the MRCD is used commonly, they shoot cars from behind as they pass the photo radar truck. Because of this, you’ll get pretty short distance alerts as you approach, but you’ll get unnecessarily long alerts from behind, long after you’ve exited the kill zone. For this reason, you can choose to turn off MRCD detection from behind.

  • *Off
  • Wide
  • Narrow

R-Gatso

Rear Gatso photo radar detection.

  • On
  • *Off

R-MR Filter

Rear MultaRadar and Gatso false alert filter.

  • Off
  • Low
  • *High

Jammer

Enables laser jammer integration. Turn on if you’re running the RC M connected to an AntiLaser Priority.

  • On
  • *Off

Parking Assistance

Controls the parking sensor capabilities of the ALP. I find the parking sensors don’t work all that well so I disable this feature myself.

  • *On
  • Off

Laser Jamming Timer

How long do you want your ALP to jam for before it automatically disarms?

Note: This is critically important when using laser jammers. When shot, you quickly slow down and disable your laser jammers so the officer can get a reading. The RC M defaults to a 6 sec AutoJTK, but I’d recommend dropping this down to 4 sec. If you want to disable even more quickly like a rock star, manually press any button on the RC M’s display once you’re down to speed.

  • *Jamming 1-9 sec
  • Unlimited (only to be used for testing)
  • Jamming Off
  • Detection Only

Laser Name

Provides a laser gun ID so you know what gun you’ve been shot with.

  • *Voice: Audible and visual announcement of laser gun
  • No Voice: Visual indication of laser gun on display only
  • Off: Simply says “Laser” on screen

Jammer Default?

Resets ALP back to factory default options. Press the middle button to reset.

1-Beep

When you detect a signal that’s previously been locked out, do you want to get one initial beep before the detector goes silent? If you want to know there’s a signal present that’s being muted, turn this on. If you’d prefer a quieter experience, turn this off.

  • On
  • *Off

Speed

Low speed muting. This mutes all signals below this threshold. (Default: 15 mph)

  • 5-130 mph in 5 mph increments

Startup Sound

Choose if you want to hear the startup sound.

  • *On
  • Off

Power Off If Display Removed

Do you want the radar detector to instantly turn off when you remove your display? This can be useful for quickly disabling your detector in banned areas. You can also have the detector stay on and continue alerting in case you need to remove your display temporarily because it’s reflecting sunlight in your eyes or something, but keep in mind you won’t be able to manually mute alerts since the control buttons are part of the display too.

  • *On
  • Off

GPS Connect Announce

Audibly indicate when your RC M gets a GPS lock once you start driving.

Vortex’s Radenso RC M Settings

Here’s the settings that I run on my RC M. I basically have it set up with fairly aggressive K band filtering since we don’t have a ton of K band in use around here, no low powered radar detection, and X band off. I’m also experimenting with different alert tones and I have it set to laser jammers off since I run my ALP’s standalone so I can use them with any RD.
