Audio Quality

Motorola RMU2040 has excellent audio quality providing clear and crisp audio meaning the RMM2050 can be used in challenging environments.

Durability & Water Resistance

Motorola RMM2050 conforms to MIL-STD-810 standard (military standard 810) which is a set of manufacturing, performance, robustness and endurance guidelines set by the US department of defense. That means you can be sure that the Motorola RMU2040 is durable enough to withstand even the most challenging conditions and environments. Motorola RMM2050 meets IP55 Ingres protection rating meaning it gives adequate dust-resistance and waterproofing from un-pressured water jets (i.e. light rain).

Frequencies, Channels & License

The Motorola RMM2050 has 5 pre-defined VHF frequencies that can be programmed into any of the 5 available channels in any order. These frequencies are designated by the FCC as the pre-defined MURS channels and are completely license-exempt.

CTCSS/DCS tones (also known as PL/DPL codes) help to exclude unwanted radio transmissions. There are 219 CTCSS/DCS tones including 6 customizable tones. By selecting a specific tone hearing unwanted radio transmissions is very unlikely.

Wallmart (also Sam's Club) Compatability

Wallmart (and Sam's Club) uses a radio called Motorola RDM2070D. RDM2070D is exclusive to Wallmart and is not available for purchase. But the good news is that the Motorola RMM2050 is compatible with the RDM2070D. To make the RMM2050 work with the RDM2070D, some basic programming is required. There's an article on which outlines the frequency order and CTCSS tones needed to make the two compatible.


The RMM2050 is supplied programmed with all 5 channels pre-programmed with the famous Blue Dot channel at channel position #1 and the Green Dot channel at position #2. The remaining 3 channels are programmed to the other 3 MURS frequencies. All channels have the CTCSS tone 67.0 Hz.

Default Channel Programming

Channel #FrequencyCTCSS/DCS Tone (#)BandwidthPower / License Type
1 154.57 MHz (Blue Dot) 67.0 (1) 20 kHz 2W, MURS
2 154.6 MHz (Green Dot) 67.0 (1) 20 kHz 2W, MURS
3 151.82 MHz 67.0 (1) 12.5 kHz 2W, MURS
4 151.88 MHz 67.0 (1) 12.5 kHz 2W, MURS
5 151.94 MH 67.0 (1) 12.5 kHz 2W, MURS

The Motorola RMM2050's 4 channels can be set to any of the pre-defined VHF MURS frequencies and any of the 219 CTCSS/DCS tones. Programming the channels is done by either directly programming the radio using advanced configuration mode (see the user guide), or by using the free programming software (you'll just need a HKKN4027 programming cable).

Cloning Programmed Channels

Once the radio is configured exactly as required, rather than programming every radio individually, the Motorola RMU2040 settings can be cloned using the PMLN6384 6-way charger, the PMLN6394 single charger (with a HKKN4028 radio to radio cloning cable), or by reading the radio then writing another using the free programming software (and a HKKN4027 programming cable).

Voice Announcements

The Motorola RMM2050 has voice annunciation meaning the radio announces events such as when the channel has been changed or when the battery is running low on power. The channels names can be customized (only be using the free programming software) to announce a customized channel name. The software uses text-to-speech to generate the channel name announcement file. When an earpiece is connected, the annunciation is also heard via the earpiece.

Call Tones

Motorola RMM2050 has 3 call tones which allow the user to notify the fleet of a call/important announcement which sends an alarm-type ring to the rest of the fleet. This feature needs to be programmed into the radio using the free programming software (HKKN4027 programming cable also required) Call tone can be assigned to any of the two programmable buttons next to the PTT.

Audio Accessory Socket & Earpiece Options

The Motorola RMM2050 has a standard Motorola-style 2-pin audio socket. This means that earpieces and other audio accessories and cost-effective. But also means there are plenty of options available including Motorola's genuine d-shape earpiece and genuine covert-earpiece.

Motorola RMM2050 also has voice-activation (also known as VOX). That means the RMM2050 can be activated by voice alone, without pushing the PTT, allowing for completely hands-free communication. All that's needed is a VOX-compatible headset or earpiece.

Chargers & Batteries

Motorola RMM2050 has two charger options. The Motorola RMM2050 is usually supplied with a single slot-in type desk charger. There's also a 6-way charger that allows the simultaneous charging of 6x RMU-series radios at the same time.

There are 3 battery options. The Motorola RMM2050 is usually supplied with the Motorola PMNN4434AR 2100mAh lithium battery which offers between 8 and 10 hours of use. However, if longer use between charges is required, there is also PMNN4453AR 3000mAh lithium battery which can offer up to 18 hours or use. Battery life between charges is usually considered 5% receive, 5% transmit, and 90% standby.
