BAOFENG GT-5R Dual Band Ham Radio Review: An FCC-Compliant Version of the Popular UV-5R


Introduction

The BAOFENG GT-5R Dual Band Handheld Ham Radio is an interesting option for amateur radio operators looking for an affordable, compact, and versatile handheld transceiver. Built around the familiar design and functionality of the popular BAOFENG UV-5R, the GT-5R brings together many of the features that have made the 5R radio family so popular while introducing an important improvement: a transmit-frequency configuration designed specifically for FCC compliance in the United States.

For amateur radio operators, having a dependable handheld radio is important. Whether communicating through local repeaters, participating in amateur radio nets, monitoring activity on the VHF and UHF bands, or keeping a radio available for emergency communications, a handheld transceiver can provide an important connection when other communication options are unavailable.

The GT-5R offers dual-band operation, programmable memory channels, selectable transmit power, dual-frequency monitoring, scanning capabilities, VOX operation, and compatibility with a variety of accessories. It also provides a familiar operating experience for anyone who has previously used a radio from the BAOFENG 5R family.

One of the biggest attractions of this particular model is its restricted transmit-frequency range. Rather than offering the broad transmit-frequency coverage associated with some versions of the traditional UV-5R, the GT-5R is configured to transmit within the designated amateur radio bands for the United States.

This makes it an appealing choice for newcomers who want an accessible first handheld radio and experienced operators who appreciate having an affordable secondary radio available.

Let's take a closer look at what makes the BAOFENG GT-5R worth considering.

Design and Construction

The BAOFENG GT-5R follows the familiar handheld design that has become recognizable throughout the amateur radio community. It features a compact rectangular body, an LCD display, a numeric keypad, front-facing control buttons, a side-mounted push-to-talk button, and a removable antenna.

Its compact dimensions make it convenient to carry in a pocket, attach to a belt, or store inside a backpack or emergency communications kit.

The overall design is straightforward and functional. Instead of introducing an unnecessarily complicated interface, BAOFENG retains the traditional 5R-style arrangement that many amateur radio operators already understand.

The front display provides important operating information, including frequency information and channel selections. The keypad provides access to frequency entry, menu functions, and programming options.

The side controls are positioned for convenient access while holding the radio. The push-to-talk button allows the operator to transmit without having to navigate through the menus.

For an inexpensive handheld transceiver, the GT-5R offers a practical combination of portability and functionality.

Its relatively small size also makes it suitable for carrying during outdoor activities, camping trips, hiking, travel, and everyday radio monitoring.

Dual-Band VHF and UHF Operation

One of the strongest features of the GT-5R is its dual-band capability.

The radio supports two important amateur radio frequency ranges:

VHF transmission: 144–148 MHz.

UHF transmission: 420–450 MHz.

For receiving, the United States version covers 136–174 MHz and 400–480 MHz.

These two operating ranges provide amateur radio operators with access to a substantial amount of local communications activity.

The 2-meter VHF band is particularly popular among amateur radio operators. It is widely used for local repeater communications, simplex conversations, amateur radio nets, public-service activities, and emergency communications.

The 70-centimeter UHF band provides another valuable communications option. Many communities have UHF repeaters that allow operators to communicate across their surrounding areas.

Having both bands available in one handheld radio gives operators flexibility when selecting frequencies and communicating with other stations.

VHF and UHF also behave somewhat differently depending on terrain, buildings, antennas, and other environmental conditions. Having access to both bands allows operators to select the frequency range that works best for their particular situation.

For someone getting started in amateur radio, having both bands available is a significant advantage.

FCC-Compliant Transmit Configuration

Perhaps the most important characteristic of the BAOFENG GT-5R is its FCC-oriented transmit configuration.

The radio is marketed as a compliant version of the traditional UV-5R. Its United States transmit range is restricted to 144–148 MHz and 420–450 MHz.

This is important because amateur radio equipment must operate within the appropriate frequency authorizations and comply with applicable emission requirements.

The GT-5R is designed to help prevent accidental transmissions outside its configured amateur radio transmit ranges.

For new amateur radio operators, this is an especially useful characteristic. Someone purchasing their first handheld radio may not yet understand all the different frequency allocations used by amateur radio operators, commercial services, public safety organizations, and other radio users.

Having the transmitter restricted to the intended amateur radio ranges provides an additional measure of confidence when programming and operating the radio.

The manufacturer also identifies the GT-5R as having compliant spurious-emission performance.

Spurious emissions are unwanted radio-frequency signals produced by a transmitter. Controlling these emissions is important because unwanted signals can interfere with other radio communications.

The GT-5R is designed to address this important aspect of transmitter performance.

Of course, operators still need to follow FCC rules, use appropriate frequencies, and hold the required amateur radio license before transmitting. The radio's restricted frequency configuration does not replace the operator's licensing responsibilities.

For operators looking for a handheld with a more controlled transmit configuration, this is one of the GT-5R's most appealing features.

Transmit Power and Performance

The BAOFENG GT-5R provides selectable high- and low-power transmission.

Its specified output power is:

  • High power: Approximately 4 watts.

  • Low power: Approximately 1 watt.

These power settings provide flexibility depending on the communications situation.

The high-power setting is useful when trying to reach a distant station or access a repeater under less-than-ideal conditions. The low-power setting can be useful when communicating with nearby stations.

Using lower power when it is sufficient can also help conserve battery capacity.

Four watts is a useful output level for a handheld amateur radio. While it cannot replace the power and antenna advantages of a base station or mobile transceiver, it is perfectly suitable for many local VHF and UHF communications activities.

Actual communication distance depends on several factors, including antenna performance, terrain, buildings, elevation, repeater coverage, and atmospheric conditions.

When operating through a well-positioned repeater, a handheld radio can communicate across a much larger area than would normally be possible using simplex communications.

The ability to choose between high and low power makes the GT-5R practical for different operating environments.

Dual-Frequency Display and Dual Standby

Another useful feature is the GT-5R's dual-frequency display.

The radio can display two frequencies simultaneously, allowing operators to monitor two different communications channels.

This is particularly convenient for amateur radio operators who regularly monitor local repeaters while keeping another frequency available.

For example, an operator might monitor a local 2-meter repeater on one display line and a UHF repeater on the other.

The dual-standby functionality adds another layer of convenience by allowing the radio to monitor two selected frequencies.

This can be useful when participating in amateur radio activities, traveling through unfamiliar areas, or monitoring different local communications channels.

Instead of constantly switching between frequencies, the operator can keep two channels available for monitoring.

For people who enjoy keeping track of local amateur radio activity, this is a valuable feature.

Memory Channel Capacity

The GT-5R provides 128 programmable memory channels.

This gives operators plenty of room to organize commonly used frequencies.

Memory channels can be programmed with local repeaters, simplex frequencies, amateur radio club nets, regional communications channels, and other permitted monitoring frequencies.

Having programmable memory makes everyday operation much easier.

Rather than manually entering a frequency every time the radio is used, operators can save frequently used channels and return to them whenever needed.

A well-organized memory system can also make the radio easier to use during emergencies or outdoor activities.

For example, an operator could organize memory channels around frequently used local repeaters and simplex frequencies.

The 128-channel capacity provides a useful amount of flexibility without making the radio unnecessarily complicated.

Programming Options and CHIRP Compatibility

Programming is an important part of owning any amateur radio handheld.

The BAOFENG GT-5R supports programming through its front keypad as well as computer-based programming.

Manual programming allows operators to enter frequencies and adjust settings directly through the radio.

For operators who want to program numerous channels, using a computer can be considerably more convenient.

The GT-5R supports CHIRP programming software, which is popular throughout the amateur radio community.

CHIRP allows users to organize radio memories, enter frequencies, configure repeater information, and transfer programming information between a computer and compatible radio.

This can save considerable time when setting up a radio for the first time.

Instead of entering dozens of repeater frequencies manually, an operator can prepare a programming file and transfer the information to the handheld.

This is particularly useful for operators who travel, participate in public-service activities, or regularly operate in different areas.

Computer programming also makes it easier to maintain an organized collection of channel information.

The availability of established programming resources and a familiar programming approach is another advantage of the GT-5R.

CTCSS and DCS Tone Support

The GT-5R supports 50 CTCSS tones and 104 DCS codes.

These functions are important when operating through amateur radio repeaters.

CTCSS stands for Continuous Tone-Coded Squelch System. DCS stands for Digital-Coded Squelch.

Both systems allow compatible radios to use tone or code settings to control which signals open the receiver's squelch.

Many amateur radio repeaters require a particular CTCSS tone or DCS code before they will accept a transmission.

Programming the correct tone is therefore an important part of configuring a handheld for repeater operation.

The availability of these tone options makes the GT-5R suitable for working with a wide variety of local repeater systems.

Operators can configure the appropriate settings for their frequently used repeaters and store everything in memory channels.

This makes it easier to move between different repeaters without having to reconfigure the radio each time.

Built-In VOX Function

The GT-5R includes VOX, or Voice-Operated Transmission.

VOX allows the radio to begin transmitting when it detects a user's voice through a compatible microphone.

This can be convenient when the operator needs to keep their hands available for another activity.

For example, someone working at an outdoor event or performing a task that requires both hands may appreciate having voice-activated transmission available.

VOX sensitivity can be adjusted to suit the operating environment.

When properly configured, it provides another way to use the GT-5R without constantly pressing the push-to-talk button.

It is a useful additional feature that adds flexibility to the radio's operation.

Scanning Capabilities

Scanning is another feature that makes the GT-5R useful for monitoring amateur radio activity.

The scan function allows the radio to search through frequencies or programmed memory channels.

This can be helpful when an operator wants to discover whether a repeater or another programmed channel is active.

For example, someone traveling through an unfamiliar area might scan their programmed repeater channels to see which systems are currently being used.

Scanning can also be useful during amateur radio events and when monitoring local communications.

Combined with the radio's dual-frequency display and programmable memory, the scanning functionality provides a convenient way to keep track of radio activity.

Built-In LED Flashlight

The GT-5R includes a built-in LED flashlight.

Although it is a relatively simple feature, having a light available directly on a handheld radio can be convenient.

A flashlight can be useful when operating outdoors after dark, looking through equipment, checking something inside a vehicle, or working in a dimly lit area.

For emergency communications kits, small additional features can sometimes make a difference.

The flashlight does not replace a dedicated emergency lighting system, but it is a useful convenience that is already built into the radio.

Emergency Alert Function

The GT-5R also includes an emergency alert function.

This provides an additional feature for situations where an operator needs to draw attention to an emergency communication.

The function is part of the radio's broader collection of features designed to make the handheld useful beyond ordinary conversations.

Amateur radio operators who participate in emergency communications appreciate having equipment that offers multiple operating functions in a compact package.

The emergency alert feature adds another option to the GT-5R's capabilities.

Operators should remember that an alert function does not automatically contact emergency services. It must be used appropriately on a frequency where its use is authorized.

FM Radio Reception

The GT-5R also includes FM broadcast radio reception.

This provides an additional listening option when the operator wants to listen to ordinary broadcast radio.

Having FM reception built into the handheld is convenient because it allows the radio to serve another purpose when the operator is not monitoring amateur radio activity.

It can be useful while traveling, camping, or spending time outdoors.

The combination of amateur radio monitoring and broadcast FM listening makes the GT-5R a versatile little communications device.

Battery and Charging

The standard GT-5R package includes an 1800mAh rechargeable lithium-ion battery.

The battery provides portable power for everyday handheld operation without requiring a constant external power connection.

The radio also includes a desktop charging cradle and power adapter.

Desktop charging is convenient because the radio can be placed into its charging cradle when it is not being used.

This makes it easy to establish a regular charging routine.

For operators who use their handheld regularly, keeping a fully charged battery available is important.

Battery operating time will depend on how frequently the radio transmits, how often it receives signals, the selected power setting, and other operating conditions.

Operators who spend extended periods away from electrical power may want to consider keeping compatible spare batteries available.

The GT-5R's compatibility with accessories from the BAOFENG 5R family provides additional flexibility when building an equipment setup.

Antenna and Accessory Compatibility

The GT-5R uses the familiar antenna arrangement found throughout the BAOFENG 5R radio family.

The supplied antenna provides a convenient starting point for ordinary handheld operation.

One of the attractive aspects of this radio is its compatibility with many accessories designed for the 5R series.

Depending on the specific accessory, operators can expand their setup with items such as:

  • Compatible replacement antennas.

  • Extended-capacity batteries.

  • External speaker microphones.

  • Programming cables.

  • Earpieces.

  • Multi-unit charging equipment.

  • Compatible carrying accessories.

This accessory compatibility gives owners room to customize their radios according to their individual operating preferences.

For example, someone who primarily operates outdoors might prefer an external speaker microphone.

An operator who participates in longer communications events may appreciate having additional compatible batteries available.

The ability to use accessories from the established 5R family makes it easier to build a useful handheld radio setup around the GT-5R.

As always, buyers should verify exact model and connector compatibility before purchasing accessories.

Using the GT-5R for Amateur Radio Repeaters

One of the best applications for the GT-5R is local repeater communication.

Repeaters are strategically positioned radio systems that receive a signal on one frequency and retransmit it on another.

This allows handheld operators to communicate across a much larger area than they might be able to reach directly.

A properly programmed GT-5R can be used to access compatible VHF and UHF amateur radio repeaters.

The operator needs to know the repeater's input frequency, output frequency, offset, and any required access tone.

Once these details are programmed into memory, using the repeater becomes relatively straightforward.

For newly licensed Technicians, repeater operation is one of the most enjoyable ways to get involved in amateur radio.

It provides opportunities to meet other operators, participate in local nets, exchange information, and become part of the amateur radio community.

The GT-5R provides the basic dual-band capabilities needed for this type of operation.

A Useful Radio for Emergency Preparedness

The BAOFENG GT-5R also deserves consideration as part of an emergency communications kit.

Amateur radio can become particularly valuable during situations where cellular networks, internet access, and conventional communication services become unavailable or unreliable.

Severe storms, power outages, flooding, winter weather, and other emergencies can create situations where having an independent communications capability is beneficial.

A handheld radio gives a licensed operator the ability to communicate with other amateur radio stations and appropriately equipped repeaters.

The GT-5R's compact design makes it easy to store inside a preparedness kit, vehicle, backpack, or emergency communications bag.

Its dual-band operation gives operators access to both VHF and UHF amateur radio communications.

The programmable memory allows important local repeater and simplex frequencies to be stored ahead of time.

The LED flashlight, rechargeable battery, scanning functions, and dual-frequency monitoring provide additional convenience.

For families interested in emergency preparedness, it is worth considering how amateur radio could become part of a larger communications plan.

However, each family member who transmits on amateur radio must have the appropriate license, and all operators should practice using their equipment before an emergency occurs.

A radio sitting inside a storage container is not particularly useful if nobody knows how to program it or operate it.

The GT-5R provides an affordable platform for developing those skills.

The GT-5R for New Amateur Radio Operators

One of the most appealing aspects of the BAOFENG GT-5R is its suitability for people entering amateur radio.

Getting started in the hobby does not necessarily require an expensive collection of equipment.

A new Technician-class operator can begin learning about repeaters, simplex communication, frequency programming, antennas, and radio operating procedures with a relatively simple handheld transceiver.

The GT-5R offers many of the functions needed for that learning process.

Its familiar keypad layout, dual-band display, programmable memory, and computer-programming compatibility provide plenty of room for beginners to develop their operating skills.

The restricted transmit-frequency configuration is also an attractive feature for newcomers who want a radio designed around the appropriate amateur radio transmit ranges.

Another benefit is the large amount of educational material available for the BAOFENG 5R family.

New operators can find programming information, operating tutorials, and discussions about the radio's features throughout the amateur radio community.

This makes learning how to use the GT-5R considerably more approachable.

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.
