Yaesu FT-2980R 80-Watt 144 MHz Mobile Transceiver Review


The Yaesu FT-2980R is a radio that takes a deliberately straightforward approach to amateur radio. Instead of trying to combine HF, VHF, UHF, digital voice, touchscreen controls, Bluetooth, GPS, and dozens of modern networking features into one package, Yaesu built the FT-2980R around one primary purpose: providing a powerful and rugged 2-meter FM mobile transceiver.

Its headline feature is right in the specifications. The FT-2980R can produce up to 80 watts on the 144 MHz amateur band, with selectable output levels of 80, 30, 10, and 5 watts. It uses a large heatsink rather than a cooling fan, and Yaesu designed the radio around conventional analog FM operation.

That simplicity is actually one of the most interesting things about the FT-2980R. For an operator who primarily works 2 meters, there is something appealing about having a dedicated VHF radio that concentrates on doing its job rather than attempting to do everything.

Design and Build Quality

The FT-2980R has the appearance of a traditional mobile amateur radio. It is approximately 6.3 inches wide, 2 inches high, and 7.3 inches deep, with a weight of about 4.2 pounds. The relatively substantial weight is partly a result of the radio's heavy-duty construction and large heatsink.

The physical design is particularly well suited to mobile installation. The chassis is substantial without being excessively large, and the mounting bracket allows the radio to be positioned conveniently beneath a dashboard, in a console, or in another suitable location.

One of the defining characteristics of the FT-2980R is its massive heatsink. Yaesu designed the radio to dissipate the heat generated by its high-power transmitter without requiring a cooling fan. This makes the radio mechanically simpler and eliminates the noise and potential maintenance associated with a fan.

For mobile operators, this is an important design decision. A fanless radio is inherently attractive when the radio is mounted inside a vehicle, particularly for operators who prefer a quiet operating environment.

The Front Panel

The front panel is traditional and practical rather than flashy. The radio features a large six-character backlit LCD display that provides good visibility while operating the radio. The display can show operating frequency information as well as alphanumeric memory labels.

The large display is particularly useful when operating while seated in a vehicle. A mobile radio should be readable without forcing the operator to stare closely at the screen, and the FT-2980R's relatively large display reflects that philosophy.

The radio also provides four levels of display dimming, allowing the brightness to be adjusted for different lighting conditions.

The controls are based around physical buttons, knobs, and the main tuning control. Operators who prefer conventional amateur-radio controls will likely find the layout familiar.

80 Watts of VHF Power

The biggest selling point of the FT-2980R is undoubtedly its 80-watt transmitter.

The radio provides four selectable output levels:

80 watts

30 watts

10 watts

5 watts

The selected power level can also be stored in memory, which makes it possible to use different power settings for different programmed channels.

The advantage of having multiple power levels is that maximum power does not have to be used all the time. A nearby repeater may require very little transmitter power, while a weak simplex contact may benefit from additional output.

The 80-watt setting is particularly useful when conditions call for maximum available transmitter power. However, it is important to understand that increasing transmitter power does not automatically produce a proportional increase in communication range. Antenna height, antenna efficiency, feed-line losses, terrain, receiver location, and propagation often have a much greater effect on VHF communication range.

The radio's maximum transmitter current consumption is approximately 15 amps at the 80-watt setting, so a properly installed power connection is important.

The 80-watt output is therefore not simply a specification to advertise on a box. It requires an appropriately sized electrical system, good connections, suitable fusing, and an antenna system capable of handling the RF power.

Fanless High-Power Operation

One of the most interesting engineering characteristics of the FT-2980R is its ability to produce 80 watts without a cooling fan.

Yaesu specifically designed the radio around a large heatsink that handles the heat generated by the transmitter.

This has several practical advantages.

First, there is no fan noise. Second, there is no cooling fan that can become clogged with dust or eventually develop mechanical problems. Third, the radio remains relatively simple internally.

There is a trade-off, however. The heatsink needs to be able to transfer heat into the surrounding environment. That means the installation should not restrict airflow around the chassis or bury the radio in a tightly enclosed location.

The heatsink can also become hot during extended high-power transmissions. This is normal for a high-power analog FM transmitter and is another reason to install the radio in a location that allows heat to dissipate.

The 144 MHz Focus

Unlike a dual-band radio, the FT-2980R concentrates on the 144 MHz amateur band.

For operators who primarily use 2 meters, that can be an advantage rather than a limitation.

The U.S. version transmits on 144–148 MHz and provides receiver coverage from approximately 136–174 MHz. Frequency steps include 5, 10, 12.5, 15, 20, 25, 50, and 100 kHz.

The radio is primarily an FM transceiver, making it especially appropriate for conventional 2-meter repeater and simplex operation.

It does not attempt to compete with multimode radios that provide HF, 6 meters, 2 meters, 70 centimeters, digital voice, or other modes. Instead, the FT-2980R remains focused on VHF FM.

That specialization is one of its defining characteristics.

Receiver Performance

A powerful transmitter is only half of a useful amateur radio. The receiver is equally important.

Yaesu equipped the FT-2980R with a double-conversion superheterodyne receiver and an Advanced Track Tuning RF front end designed to provide protection against intermodulation distortion.

The published receiver sensitivity is better than 0.4 microvolts at 12 dB SINAD under the specified measurement conditions. Receiver selectivity is specified at 12 kHz/28 kHz for wide FM and 9 kHz/22 kHz for narrow FM.

In practical terms, the FT-2980R is designed to be a serious VHF receiver rather than merely a high-powered transmitter.

The RF front-end design is particularly important in areas where multiple VHF signals are present. Strong signals from nearby transmitters can sometimes cause problems for receivers, so good front-end filtering can make a significant difference.

For operators in busy VHF environments, the receiver design is one of the more important reasons to consider the FT-2980R.

Three Watts of Audio

Another useful feature is the built-in three-watt audio amplifier.

Yaesu designed the FT-2980R with relatively strong internal audio output for use in noisy environments. The published specification is 3 watts into a 4-ohm load at 10 percent THD.

This makes sense for a mobile radio. Road noise, engine noise, ventilation systems, and other environmental sounds can make weak radio audio difficult to hear.

The radio also supports an external speaker, giving operators another option if the internal speaker is not sufficient for their installation.

CTCSS and DCS

The FT-2980R includes both CTCSS and DCS encoding and decoding.

These tone systems are commonly used with amateur repeaters and can also be useful for controlling which signals open the receiver squelch.

An important feature is that CTCSS and DCS information can be stored independently with memory channels. The radio also supports split-tone operation, allowing different tone systems to be used for transmit and receive when required.

For repeater users, this makes the radio considerably more flexible than a basic VHF transceiver.

Repeater Operation

The FT-2980R is well suited to conventional 2-meter repeater operation.

It supports standard repeater shifts and programmable offsets, as well as automatic repeater shift in appropriate operating configurations. The radio also supports CTCSS and DCS tones, which cover many common repeater-access requirements.

For someone programming a collection of local repeaters, the memory system becomes particularly useful.

Once the repeater frequency, offset, tone, power level, and other settings are stored, switching between repeaters becomes much easier than manually entering every setting.

The Memory System

The FT-2980R provides a surprisingly comprehensive memory system for a radio with such a straightforward operating philosophy.

Yaesu specifies 221 memory locations in total: 200 regular memories, 10 pairs of band-limit memories, and a dedicated Home channel.

The regular memories can store important operating information such as frequency, repeater shift, CTCSS or DCS information, power level, scanning status, and alphanumeric labels.

That means the memory system can be used for much more than simply storing frequencies.

For example, one memory can be programmed for a local repeater at 30 watts, another for a simplex frequency at 10 watts, and another for a distant repeater at 80 watts.

The ability to store the power setting with the memory is particularly useful.

Alphanumeric Labels

The radio supports alphanumeric labels of up to six characters for memory channels.

This is a small feature that becomes increasingly valuable as the memory bank fills.

Instead of remembering which memory contains which frequency, the operator can use labels to identify channels.

For example, a memory can be labeled with a short repeater identifier, location, or other abbreviation.

For mobile operation, this can make the radio easier to use because the operator does not have to memorize a long list of frequencies.

NOAA Weather Reception

The U.S. version includes a dedicated group of 10 NOAA Weather Broadcast memories. The FT-2980R can also use a 1050-Hz weather alert function to notify the operator when a qualifying severe-weather alert signal is received.

This is a useful additional capability for a mobile VHF radio.

Rather than manually tuning through weather frequencies, the operator can access the dedicated weather channels directly.

The weather alert capability can also be configured to monitor the weather channels and respond when the appropriate alert tone is detected.

Smart Search

Another useful feature is Yaesu's Smart Search function.

Smart Search automatically scans a portion of the band and can load active frequencies into dedicated memory locations. Yaesu describes this as particularly useful when an operator is visiting an unfamiliar area and wants to identify active frequencies.

This is a nice feature for exploring the local VHF environment without manually checking every frequency.

Scanning Features

The FT-2980R includes multiple scanning capabilities.

The memory system supports scan-related functions, and the radio includes programmable band-limit memory pairs. This allows operators to define portions of the frequency range for scanning.

Memory scanning can also be useful when monitoring a collection of frequently used repeaters or simplex channels.

For an operator who spends a lot of time monitoring VHF activity, scanning can turn the FT-2980R into a useful monitoring receiver rather than simply a push-to-talk radio.

DTMF Microphone

The supplied MH-48A6JA microphone includes DTMF controls.

This is important because the microphone can provide direct access to functions that would otherwise require interaction with the radio's front panel.

DTMF is also useful for interacting with systems that use DTMF commands, including certain Internet-linked repeater systems.

The microphone's keypad makes frequency entry and certain control functions more convenient.

WIRES and Internet-Linked Repeater Access

The FT-2980R includes a dedicated capability for accessing Yaesu WIRES-related functions and other Internet-linked repeater systems that use DTMF control.

This gives the radio a connection to a much broader amateur-radio ecosystem while keeping the actual transceiver itself relatively simple.

It is important to understand that the radio is still fundamentally an analog FM transceiver. The Internet linking occurs through compatible repeater infrastructure rather than through the FT-2980R becoming an Internet-connected radio by itself.

Wide and Narrow FM

The FT-2980R supports both wide and narrow deviation settings.

The published specifications list maximum deviation of ±5 kHz for wide FM and ±2.5 kHz for narrow FM.

This provides flexibility when operating on different VHF systems.

It is important to use the appropriate bandwidth for the channel and operating requirements rather than assuming that wide FM is always preferable.

RF Squelch

In addition to conventional squelch operation, the FT-2980R provides RF squelch functionality.

This can be useful for controlling receiver operation based on signal strength rather than simply relying on a conventional squelch threshold.

The feature adds another level of control for operators who want more flexibility when monitoring VHF activity.

Power Requirements

The FT-2980R operates from a nominal 13.8-volt DC supply. The specifications allow an operating voltage range of approximately 11.7 to 15.8 volts.

The most important point for installation is the current requirement at high power.

At 80 watts, the transmitter can draw approximately 15 amps.

This means the power wiring should be appropriately sized and properly fused.

A high-power VHF radio should not be installed using undersized wiring or questionable connectors. Voltage drop can become a problem, particularly when the radio is transmitting at maximum output.

The supplied DC power cable and appropriate fusing should be used as part of a properly planned installation.

Antenna Considerations

The FT-2980R uses a standard 50-ohm antenna system.

The radio's 80 watts of RF output makes antenna quality particularly important. A poor antenna installation can waste much of the transmitter's power while also creating unwanted reflected power.

A good 2-meter antenna mounted in a favorable location can make a much larger difference than simply increasing transmitter output.

For a mobile installation, antenna placement, ground-plane considerations, feed-line quality, connector installation, and antenna tuning all deserve attention.

For a base station, antenna height becomes particularly important because VHF communications are strongly influenced by line of sight and terrain.

Simplex Operation

The FT-2980R is also an excellent platform for 2-meter simplex operation.

The four selectable power levels allow the operator to choose an appropriate output for the situation.

Five watts may be sufficient for a short-range contact. Ten or 30 watts can provide additional margin. Eighty watts gives the radio its maximum transmitter capability when conditions require it.

However, operators should remember that higher power does not eliminate the basic characteristics of VHF propagation.

A good antenna at a good location is often more valuable than simply adding more watts.

The Importance of Antenna Height

One of the biggest mistakes new operators can make is assuming that an 80-watt radio automatically means extremely long range.

VHF communication is heavily influenced by antenna height and line of sight.

An 80-watt FT-2980R connected to a poor antenna mounted in a poor location can perform worse than a lower-powered radio connected to a good antenna mounted high above surrounding obstructions.

This is why the complete station should be considered as a system.

The radio, coaxial cable, connectors, antenna, mounting location, and surrounding terrain all contribute to the final result.

Mobile Installation

The FT-2980R makes a natural choice for a dedicated 2-meter mobile installation.

Its relatively compact chassis allows it to fit into many vehicles, while the mounting bracket provides a secure method of installation.

The radio should be installed where the display and controls can be accessed safely and where the heatsink has adequate room to dissipate heat.

The microphone should also be mounted in a convenient location that allows it to be used without creating an unsafe distraction while driving.

Base Station Use

Although designed as a mobile radio, the FT-2980R can also serve effectively as a 2-meter base station.

A suitable 13.8-volt power supply can provide the required DC power, while an external antenna can provide substantially greater performance than a typical mobile antenna.

A base station installation also makes it easier to take advantage of antenna height.

A properly installed outdoor VHF antenna can significantly expand the coverage area compared with an antenna mounted inside a vehicle.

Programming the Radio

The FT-2980R can be programmed directly from its controls and microphone.

The basic learning curve is reasonable, but the radio has enough functions that new operators should spend some time with the manual.

The menus provide access to numerous configuration options, and the memory system is considerably more sophisticated than the radio's simple exterior might suggest.

The best approach is to program frequently used frequencies and repeaters first, then gradually learn the additional functions.

This avoids overwhelming a new operator with every feature at once.

Who Is the FT-2980R For?

The FT-2980R is particularly well suited to several types of amateur-radio operators.

It is an excellent choice for someone who wants a dedicated 2-meter mobile radio.

It also makes sense for operators who value high transmitter power.

It is appealing to people who prefer physical controls and a conventional radio interface.

It is also a good fit for operators who want a strong analog FM receiver and transmitter without paying for features they may never use.

For a dedicated 2-meter station, the FT-2980R's specialization can actually be a benefit.

Who Might Want Something Else?

The FT-2980R is not a universal amateur-radio transceiver.

Someone looking for both 2 meters and 70 centimeters will need a dual-band radio.

Someone interested in C4FM System Fusion, DMR, D-STAR, APRS, integrated GPS, touchscreen interfaces, or other modern digital features should look at radios specifically designed around those capabilities.

Likewise, an operator who wants HF operation will need a different transceiver.

The FT-2980R is best understood as a specialized 144 MHz FM radio rather than a do-everything amateur transceiver.

The Advantages of 80 Watts

The 80-watt capability is the feature that immediately separates the FT-2980R from many conventional VHF mobile radios.

More power can provide additional signal margin when communicating through marginal conditions, particularly when combined with an efficient antenna system.

However, the 80-watt capability is most useful when treated as additional operating headroom rather than as a guarantee of extended range.

The operator still has to contend with terrain, antenna height, feed-line loss, receiver performance, interference, and propagation.

The ability to select 5, 10, 30, or 80 watts makes the radio much more flexible than a transmitter that operates at only one power level.

The Advantages of a Fanless Design

The fanless design is another major strength.

A large passive heatsink is mechanically simple, quiet, and does not depend on a cooling fan.

For an amateur-radio operator who wants a radio that can sit in a vehicle or shack for years with relatively little mechanical complexity, this is an appealing design.

The trade-off is that installation needs to allow the heatsink to dissipate heat effectively.

Build Quality and Longevity

The FT-2980R has the kind of design that gives it an old-school amateur-radio feel.

It is not trying to be fashionable.

It is trying to be useful.

The large heatsink, physical controls, traditional display, straightforward analog FM architecture, and dedicated VHF design all contribute to a radio that feels purpose-built.

That approach can be especially attractive to operators who prefer equipment that concentrates on fundamental radio functions.

One important consideration when buying any older or legacy radio is availability. Yaesu currently lists the FT-2980R among its legacy products, so buyers should pay attention to whether they are purchasing new old stock, remaining dealer inventory, or a used unit.

Overall Performance

The FT-2980R's strongest characteristic is that it is exceptionally focused.

It does not try to do everything.

It is a high-power 2-meter FM mobile transceiver with a strong receiver, substantial cooling system, useful memory capacity, good repeater support, weather reception on the U.S. version, and straightforward controls.

The 80-watt transmitter gives the operator considerable output capability, while the selectable 30-, 10-, and 5-watt settings make it possible to use substantially less power when maximum output is unnecessary.

The receiver's Advanced Track Tuning front end, 3-watt audio output, CTCSS/DCS support, scanning functions, Smart Search, and extensive memory system make it much more capable than its simple appearance might suggest.

Final Thoughts

The Yaesu FT-2980R is a classic example of the idea that a radio does not have to be complicated to be useful.

Its entire design revolves around 144 MHz FM operation.

The 80-watt transmitter is the headline feature, but the radio is much more than simply a high-power transmitter. Its receiver, memory system, repeater functions, CTCSS and DCS capabilities, Smart Search, weather functions, DTMF microphone, scanning features, strong audio output, and rugged heatsink make it a very capable 2-meter station.

The fanless cooling system is particularly appealing, and the ability to select four different power levels makes the radio practical for everything from short-range local operation to situations where maximum transmitter output is useful.

Its biggest limitation is also its defining characteristic: it is a single-band analog FM radio.

For an operator who wants a modern digital, dual-band, multimode, or HF transceiver, there are other choices that provide those capabilities.

For the operator who wants a dedicated, powerful, straightforward 2-meter FM mobile radio, however, the FT-2980R remains an interesting piece of Yaesu engineering.

It is a radio built around a simple philosophy: concentrate on 2 meters, provide a strong transmitter, give the receiver serious attention, make the controls practical, and build the chassis to handle the heat.

That straightforward approach is what makes the FT-2980R worth considering for anyone building a dedicated 2-meter amateur-radio station.

Radioddity DB35-UV Dual Band Mobile Radio 35W Review


The Radioddity DB35-UV is a compact dual-band mobile radio designed for amateur radio operators who want more capability than a handheld transceiver can provide without moving up to a large, complicated mobile station. With 35 watts of output power, VHF/UHF operation, a detachable faceplate, multiple operating modes and a relatively compact installation footprint, the DB35-UV is an interesting option for vehicles, home stations, field operations and emergency communications.

Radioddity has become increasingly well known for producing affordable radios aimed at both newcomers and experienced operators. The DB35-UV fits that philosophy particularly well because it attempts to combine the useful features of a traditional mobile transceiver with an installation-friendly design.

What Is the Radioddity DB35-UV?

The Radioddity DB35-UV is a dual-band mobile transceiver intended primarily for amateur radio use on the VHF and UHF bands. Its 35-watt output places it between a typical handheld radio and the 50- to 75-watt mobile radios commonly found in larger vehicle installations.

One of its most useful design features is the detachable control head. Instead of having the entire radio body mounted directly behind the dashboard or within easy reach of the operator, the main radio chassis can be installed elsewhere while the faceplate and controls are positioned where they are convenient to access.

That can make a significant difference in modern vehicles where dashboard space is limited.

The radio is also small enough to work well in applications where a full-size mobile transceiver would be inconvenient.

Design and Build Quality

The DB35-UV has the appearance of a modern compact mobile radio rather than a traditional large amateur transceiver. Its relatively small footprint makes it easier to install in vehicles, workshops, temporary communications stations and other locations where space is limited.

The detachable faceplate is arguably one of its most important physical features.

For vehicle operators, this provides much greater flexibility when deciding where the radio should be installed. The radio chassis can be positioned under a seat, inside a suitable compartment or elsewhere in the vehicle, while the control head can be mounted in a convenient location.

This is particularly useful for vehicles that have limited dashboard space.

The compact design also makes the DB35-UV interesting for portable communications setups. A radio of this size can be incorporated into an emergency communications box or field station without consuming the space required by a larger mobile transceiver.

As with any compact radio, however, installation should provide adequate ventilation. Even though the DB35-UV is not an extremely high-powered transmitter, transmitting at higher power for extended periods generates heat.

35 Watts of Transmitting Power

The 35-watt output is one of the biggest advantages of the DB35-UV.

A typical handheld amateur radio operates at only a few watts. Increasing transmitter power to 35 watts can provide considerably more effective communication capability when combined with a properly installed external antenna.

It is important to remember that transmitter power alone does not determine range.

A 35-watt mobile radio connected to a poor antenna can perform worse than a lower-powered radio connected to an excellent antenna.

For mobile operation, antenna location, antenna efficiency, feed-line quality and vehicle installation all matter.

Nevertheless, 35 watts provides a useful amount of power for:

The additional power is especially useful when the radio is being used with a good roof-mounted mobile antenna.

Dual-Band Operation

The DB35-UV is designed for operation on both VHF and UHF amateur radio frequencies.

This gives the operator considerably more flexibility than a single-band mobile transceiver.

VHF is commonly used for 2-meter amateur radio communications, while UHF is widely used for 70-centimeter communications. Both bands have extensive repeater networks throughout the United States.

Having both available in the same radio means an operator does not need separate radios for basic VHF and UHF mobile communications.

This can be especially useful for someone traveling between different areas because repeater systems vary considerably from location to location.

A dual-band radio can also be useful during emergency communications when one band is being used for a primary communications channel and another is being used for coordination or monitoring.

The Detachable Faceplate

The detachable faceplate deserves special attention because it changes how the radio can be installed.

Traditional mobile radios generally require the complete radio chassis and control panel to occupy the same location. That can be difficult in newer vehicles where manufacturers have integrated large infotainment screens, climate controls and other electronics into the dashboard.

With the DB35-UV, the radio's main body can be placed somewhere else.

This opens up several installation possibilities.

The control head could potentially be positioned near the driver while the radio chassis is installed underneath a seat or in another appropriate location.

For a home station, the detachable design can also make it easier to place the radio controls on a desk while keeping cables and the main chassis organized elsewhere.

For an emergency communications box, the detachable faceplate may allow the operator to create a much cleaner installation.

Display and Controls

The control interface is designed around the needs of mobile radio operators.

A mobile transceiver needs to allow the operator to quickly identify the active frequency or channel, adjust settings and change operating parameters without spending excessive amounts of time navigating menus.

This becomes particularly important when the radio is being used inside a moving vehicle.

The DB35-UV's control head makes it possible to keep the important controls within reach while the main radio remains out of the way.

New operators may need some time to become familiar with the menu system. This is common with modern amateur radios because manufacturers increasingly provide a large number of functions in relatively small radios.

Once configured, however, many operators will likely spend most of their time using stored channels rather than manually entering frequencies.

Repeater Operation

One of the primary reasons many amateur radio operators install a mobile radio is repeater access.

The DB35-UV can be used for conventional VHF and UHF repeater communications when properly programmed for the repeater's frequency, offset and tone requirements.

A properly programmed repeater channel can make mobile operation extremely convenient.

Instead of manually entering the repeater frequency every time, the operator can simply select the stored channel.

This is especially useful when traveling.

An operator can program repeaters along a planned route before leaving home and then move through the channel list as they travel.

Programming

Programming is an important part of getting the most from any modern mobile radio.

The DB35-UV offers numerous programmable settings, allowing the operator to configure frequencies and other operating parameters.

For someone purchasing the radio as a first mobile transceiver, programming can initially seem complicated.

That isn't necessarily a criticism of this particular radio. Modern amateur radios simply have a lot of functionality packed into a relatively small package.

The best approach is to create an organized channel plan.

For example, an operator might create groups for:

Local Repeaters

Nearby repeaters can be programmed together for everyday communications.

Travel Repeaters

Repeaters along frequently traveled routes can be stored separately.

Simplex Channels

Common VHF and UHF simplex frequencies can be organized into their own group.

Emergency Communications

Locally appropriate emergency and public-service channels can be programmed according to applicable amateur-radio rules and local communications plans.

A well-organized memory system can make the radio much easier to use.

Mobile Performance

The DB35-UV makes a lot of sense as a vehicle radio.

Its 35-watt output provides a substantial increase over a handheld transceiver, while the compact chassis helps simplify installation.

The biggest performance improvement will generally come from combining the radio with a good external antenna.

A properly installed dual-band antenna mounted in a favorable location can make a tremendous difference.

A magnetic-mount antenna can be convenient for temporary installations, while a permanently mounted antenna can provide a more robust long-term solution.

For serious mobile operation, antenna placement should be given at least as much attention as the radio itself.

Home Station Use

Although the DB35-UV is marketed as a mobile radio, there is no reason it cannot serve as the centerpiece of a small VHF/UHF home station.

With an appropriate power supply and outdoor antenna, the radio can become a useful local communications station.

This can be an attractive option for someone who does not need HF capability but wants dependable VHF/UHF communications.

A home operator could use it for:

  • Local repeater communications
  • VHF simplex
  • UHF simplex
  • Community communications
  • Weather monitoring
  • Amateur radio club activities
  • Emergency communications
  • Public-service events

The radio can also serve as a useful secondary station alongside an HF transceiver.

Emergency Communications

The DB35-UV has considerable potential as an emergency communications radio.

The combination of dual-band operation, 35 watts of power and a detachable control head makes it suitable for vehicle-based emergency communications.

During a power outage or other emergency, a properly equipped vehicle can become a useful communications platform.

An operator could have the radio connected to an external antenna, powered by the vehicle electrical system and used to access local repeaters or simplex networks.

It can also be incorporated into a dedicated emergency communications box.

For preparedness-minded amateur radio operators, this is an appealing characteristic.

The radio isn't a complete emergency communications system by itself, however.

A serious emergency setup should also include backup power, spare fuses, suitable coaxial cable, antenna options, backup communication methods and a way to operate if the vehicle becomes unavailable.

Power Requirements

Like other mobile transceivers, the DB35-UV needs a suitable DC power source capable of supplying the necessary current during transmission.

A vehicle battery and charging system normally provide the required power for mobile operation.

For home use, the radio should be paired with an appropriate regulated DC power supply.

One advantage of a 35-watt radio is that it doesn't require the same level of power infrastructure as a high-power HF station.

That makes it easier to integrate into portable and backup-power systems.

For emergency use, operators should consider how long they expect to operate and how much battery capacity will be required.

Receiving generally consumes considerably less power than transmitting, so operating style has a major impact on battery endurance.

Audio Quality

Audio is an important consideration for any mobile transceiver.

The operator needs to clearly hear other stations, particularly when driving or operating in environments with significant background noise.

The DB35-UV's compact design means the speaker arrangement and installation location can have an impact on perceived audio quality.

Mounting the radio or control head where the speaker is not obstructed can help.

For noisy vehicles, an external speaker can also be considered if the installation supports one.

This is one area where installation matters almost as much as the radio itself.

Who Is the DB35-UV Best For?

The Radioddity DB35-UV is particularly well suited to several types of amateur radio operators.

New Amateur Radio Operators

Someone who has earned a Technician license and wants to move beyond a handheld radio may find the DB35-UV appealing.

It provides substantially more output power than a typical handheld while retaining access to the popular VHF and UHF bands.

Mobile Operators

This is perhaps the radio's strongest target audience.

The compact chassis and detachable faceplate make it particularly attractive for vehicle installations.

Emergency Communications Operators

Operators interested in emergency preparedness can use the DB35-UV as part of a larger mobile communications system.

Field Operators

Its compact size makes it practical for temporary communications stations where space and portability are important.

Home VHF/UHF Operators

Someone who primarily uses local repeaters and simplex communications may not need an expensive high-end base station.

The DB35-UV can provide a relatively compact alternative.

Who Might Want Something Else?

The DB35-UV is not going to satisfy every amateur radio operator.

An operator interested primarily in HF DXing, contesting or long-distance HF communications will need a radio designed for those bands.

Likewise, someone who wants maximum transmitter power may prefer a larger 50-watt or 75-watt mobile transceiver.

Operators who want advanced digital networking capabilities should also carefully compare the radio's capabilities with their requirements before purchasing.

The DB35-UV is best understood as a compact VHF/UHF mobile transceiver rather than an all-band communications platform.

Advantages

The DB35-UV has several characteristics that make it attractive.

35-watt output provides substantially more power than a handheld.

Dual-band capability allows access to both VHF and UHF communications.

Detachable faceplate provides installation flexibility.

Compact design makes the radio suitable for vehicles with limited space.

Mobile and base-station versatility allows it to be used in more than one environment.

Emergency communications potential makes it useful as part of a preparedness communications setup.

External antenna compatibility allows the operator to significantly improve performance compared with a handheld antenna.

Potential Disadvantages

There are also some considerations to keep in mind.

The radio's compact size means that the operator needs to become familiar with its controls and menu system.

Programming modern radios can also require some patience, particularly for new operators.

The 35-watt output is useful but isn't equivalent to a high-power mobile transceiver.

And as with every VHF/UHF radio, the antenna installation can have a tremendous effect on real-world performance.

A poor antenna cannot be completely compensated for by additional transmitter power.

Antenna Recommendations

If you purchase a DB35-UV, don't overlook the antenna.

A good dual-band antenna can dramatically improve the usefulness of the radio.

For vehicle installations, a quality roof-mounted dual-band antenna is an excellent choice when permanent installation is practical.

For temporary installations, a magnetic-mount antenna may be more convenient.

For home stations, an outdoor vertical antenna mounted as high and clear as practical can provide much better coverage than a small indoor antenna.

Coaxial cable should also be selected carefully and installed properly.

The radio, coax and antenna should be considered one complete RF system.

Final Verdict

The Radioddity DB35-UV is an interesting compact mobile transceiver for amateur radio operators who want more power and capability than a handheld without installing a large mobile radio.

Its combination of 35 watts, dual-band VHF/UHF operation and a detachable faceplate gives it considerable flexibility.

The detachable control head is particularly valuable for modern vehicle installations because it allows the operator to separate the controls from the main radio chassis.

For someone building a mobile amateur radio station, an emergency communications vehicle, a compact home VHF/UHF station or a portable field communications system, the DB35-UV deserves serious consideration.

Its greatest strength isn't simply the 35-watt transmitter. It is the combination of useful power, dual-band operation and installation flexibility in a relatively compact package.

As with any amateur radio installation, however, the final performance will depend heavily on the antenna, installation, programming and operating environment.

For operators who primarily need reliable VHF and UHF communications, the Radioddity DB35-UV represents a practical and versatile approach to mobile amateur radio.
