Radenso RC M update: Improved Audio Alerts with Firmware 22

Radenso just released firmware update 22 for the RC M that adds some welcome updates to the radar and laser audio alerts. Performance and filtering are otherwise unchanged in this update.

Custom Alert Tones

The first change includes 15 selectable alert tones for X, K, Ka, MRCD, MRCT, Gatso 3, Gatso 4, and Laser.

Personally I’m not a huge fan of the RC M’s default tones. The default K band beep was always louder and more attention grabbing than the Ka beep (K band was also a double beep while Ka was a single beep, the opposite of most radar detectors) so now we have the option to change the tones to something we find more suitable and better balanced.

I’m still experimenting with my preferred alert tones and it is taking some time to get used to brand new alert tones again, but I’m really grateful for the option to change things up to something I like better.

Laser Gun ID Announcements

The second update is for people running an AntiLaser Priority laser jammer connected to the RC M with the ALP bridge cable.

When you get shot with laser, the RC M now has the ability to visually display and audibly speak which gun you were shot with.

Before it would simply say “Laser” on the display and beep. Now it can show you and tell you exactly which gun you were shot with, something that previously would only work if you ran the ALP separate from the RC M.

This is one of the main reasons that I have previously preferred to run the two standalone. Now you get one of the key features available when you run them paired together.

    Hey nice to know that you’re an engineer as well as an enthusiast in radar detectors.
    My question is why is it that the big companies like Radenso,Escort,Uniden etc.. having engineers that
    work on BNS filtering all day lone not all have the ability to do same K band false alerts. They all know how to discriminate frequencies.Why Is it that if one company finds the right K band frequency for Instance Mazda or an Acura that they don’t follow suit with that same frequency found by the company the found it first.

    1. Because knowing the frequency alone is not enough to differentiate between a legitimate and a false alert. Police radar guns use the same frequencies as non-police radar sources and so you need to look at other things like the frequency modulation and whatnot to tell the difference. Not every radar detector looks at a signal closely enough to do so and even the ones that do, you need really talented people constantly working on it which is tough too because most talented engineers get scooped up by companies like Google, Microsoft, or Boeing. It’s tough to get good talent and have them stick around in smaller industries like radar detectors.

    For the hardware+installation difference of $2000 over a windshield mounted Uniden R7, do you feel there is enough advantages to the RC-M to pay that much extra? Curious what you would personally do in this situation. Thanks!

    1. If it’s worth it is always up to each individual person, your needs, and your budget. If you want a hidden and cleaner install, ALP integration, improved BSM filtering, improved MRCD/CT support, and so on, then yes. If you just want range and arrows, then no.
