Motorola XT420 review: license-free business radio

Motorola XT420 at a glance

The XT420 is a hand-held business radio from Motorola Solutions for shops, hotels, schools and building sites. It uses PMR446, the European radio band that needs no license and no subscription. The one thing to know: it has no screen, so the radio speaks the channel to you.

Motorola also sells the XT460, a sister model with a display. Both share one data sheet and the same radio: 0.5 W, 16 channels, IP55 and a 2150 mAh battery. The XT460 weighs 256 g, against 244 g for the XT420.

Who the XT420 is for

The XT420 suits a team that works in one building or on one site. Staff turn one knob to change channel, and a voice names it. Motorola offers 16 ready-made channel names in 10 languages, or you can upload your own recording.

Pick something else in three cases. If staff need to read the channel or a name on a screen, look at the XT460. For several buildings or a large campus, a licensed radio such as the Hytera PD405 or the Motorola R7 transmits with 4 to 5 W. For a family trip or a hike, see PMR446 walkie-talkies.

Motorola XT420 range: the claim and real use

Motorola claims coverage of up to 16,250 square meters, 13 floors or 9 km in line of sight. Line of sight means a clear straight path between two radios, such as two hilltops. A footnote on the data sheet says coverage varies with terrain and conditions.

The user guide is more careful. The best range comes in flat, open areas. Steel, concrete, thick foliage, vehicles and a belt or pocket position all cut it.

The law caps PMR446 at 0.5 W, so regulators give lower numbers. The Latvian regulator expects a few hundred meters in a city and up to a few kilometers in the countryside. CEPT's ECC Report 369 simulates 0.7 to 1.0 km on rural land for 95 percent of connections, and about 0.1 km in a city.

For a shop or site, plan on one building plus its yard. Every concrete floor, steel shelf and cold-store wall takes some range away. The range tool estimates your own case with the radio's power.

Motorola XT420 battery and charging

Motorola claims up to 20 hours at a 5/5/90 duty cycle with battery save on. That pattern means 5 percent of the time sending, 5 percent listening and 90 percent idle. A guide table gives 16 hours with battery save off.

The battery is a 3.7 V lithium-ion pack of 2150 mAh. The sources describe no AA option.

The radio comes with a drop-in tray charger and a power supply with adapters for your region. The guide gives up to 4.5 hours on the standard charger and up to 2.5 hours on the rapid one.

Turn the radio off while it charges, or it will not fill fully. An optional multi-unit charger holds up to 6 radios or batteries.

Channels, privacy codes and which radios it talks to

The XT420 has a 16-position channel knob and 219 privacy codes: 38 CTCSS and 181 DCS. CTCSS is a quiet tone that opens the speaker only for your group. DCS does the same with a digital code.

A code keeps other groups' chatter out, but it does not make a call secret.

Each knob position stores its own frequency, code and scan setting. In the factory profile, positions 1 to 8 use the eight standard PMR446 channels with a 67.0 Hz tone.

Positions 9 to 16 repeat those eight frequencies with DCS code 754 (number 121 in Motorola's list). Motorola says only 446.0 to 446.1 MHz is active by default.

The radio is analog FM, so it talks to other analog PMR446 radios when the frequency and code match. The Kenwood PKT-23 uses the same eight lower channels.

For a mixed group, set the code to 0, which turns the tone off, then add a code once the call works. The compatibility tool shows which radio types can talk.

Voice scrambling is also built in. Motorola says it garbles speech for anyone not set to the same scramble code. It is analog scrambling, not digital encryption.

Where the XT420 is legal

PMR446 is license-free across Europe. An ECC decision tells CEPT countries to exempt the band from individual licenses.

The UK does the same through an Ofcom exemption, Germany through a general assignment and France through a general authorization. Those rules allow business use.

The rules are the same in each country. The radio must be hand-held with a built-in antenna and at most 0.5 W ERP, which is the power measured at the antenna. Base stations and repeaters are not allowed.

The US has no PMR446 service, because 446 MHz sits inside the US 70 cm amateur band. See do you need a license for a walkie-talkie for country rules.

Build, water and controls

The XT420 is rated IP55. The first 5 means dust cannot get in enough to harm the radio. The second 5 means it survives water jets from a nozzle.

Motorola says it is designed to meet Military Standard 810 C to G and has an antimicrobial coating. It weighs 244 g and measures 116 by 58 by 40 mm with the standard battery.

The radio works from -30 to +60 C. The Li-ion battery is rated down to -10 C, so keep a radio warm in a cold store.

To switch on, turn the volume knob clockwise. You hear a tone and the channel name, and the LED blinks red. Turn the channel knob to change channel.

Hold the PTT button on the side to talk, and release to listen. PTT means push to talk.

Two side buttons are programmable. By default SB1 monitors the channel when held, and SB2 scans. Monitor means listening before you speak, so you do not talk over someone.

A 2-pin connector under a cover takes audio accessories.

Limits of the XT420

It has no display and no keypad. You learn the channel by voice, and you set most things by software or button combinations. It has 0.5 W of power and a fixed antenna, so it will not cover a large site.

Motorola's data sheet lists no GPS, Bluetooth, emergency button or man-down alarm. The XT420 is not a system radio: it talks radio to radio on shared channels. Anyone nearby on the same channel and code can hear you.

Setup takes some work. Front-panel programming is guided by voice prompts: hold PTT and SB1 while powering on for 3 to 5 seconds. For more settings you need Motorola's free software and a programming cable sold separately.

The software can lock the front panel and set a password. You can then copy one radio's settings to others with a multi-unit charger.

How the XT420 compares

The Kenwood PKT-23E is the pocket option. It weighs 110 g, has 8 channels and IP54, and Kenwood claims up to 15 hours at 5/5/90. It is discontinued, and Kenwood publishes no range figure.

The Motorola Talkabout T82 Extreme is a family radio on the same band. Motorola claims up to 10 km and 18 hours, and lists IPX4. It has 121 codes against the XT420's 219 and runs on a NiMH pack or 3 AA batteries.

The Hytera PD405 is a licensed DMR radio, with 4 W on UHF and IP55. In the UK, Ofcom's Business Radio Simple UK Light license costs 75 pounds for 5 years. Hytera claims 12 hours analog and 16 hours digital at 5/5/90 on the standard pack.

How big is the Motorola XT420?

The Motorola XT420 next to other radios, a phone and a bank card, drawn to scale. Pick up to three to compare.
