Introduction
The Radtel RT-950 PRO positions itself as a do-it-all handheld radio aimed at users who want more than a basic walkie-talkie. From the product title you provided, the RT-950 PRO advertises 27 MHz transmit with GPS/APRS, a claimed 10-watt output, broadband receive across AM/FM/CB/SW/MW/LW, Bluetooth APP programming, NOAA weather reception, and it ships with a programming cable and microphone. That combination of features makes the RT-950 PRO an intriguing option for hobbyists, emergency-preparedness users, and anyone who wants a single hand-held unit that can receive many radio services and also act as a capable transceiver for select bands. This review looks at the radio’s design, core features, real-world performance expectations, usability, and whether it’s a good fit for different users.

What’s advertised in the box
the package includes:

  • The Radtel RT-950 PRO handheld transceiver

  • Programming cable

  • External microphone

  • Rechargeable battery (assumed)

  • Antenna

  • User manual


Key specifications (as advertised)

  • Transmit frequency: 27 MHz

  • GPS and APRS functionality

  • Receive: AM, FM, CB, SW, MW, LW

  • Bluetooth for app-based programming

  • NOAA weather reception

  • Accessories: programming cable, microphone

Design and build quality
The RT-950 PRO follows the traditional handheld transceiver shape: a rectangular body with a display and control cluster on the front, a side PTT and function keys, and an antenna connector on top. The housing is generally plastic; solid-feeling plastics are the norm at this price tier and balance weight with durability. Expect rubberized buttons for tactile feedback and a removable battery pack to facilitate swapping in the field. Ports (for microphone, programming, and USB or charging) are usually covered with rubber flaps. Overall fit and finish are likely good for casual to moderately heavy use; however harsh industrial or professional use could reveal limits typical of consumer-focused handhelds.

Display, controls, and ergonomics
Radios that pack many modes into a handheld often need thoughtful user interface design. On a unit offering GPS, APRS, Bluetooth, and multi-band receive, you’ll typically see:

  • A color or backlit LCD that shows frequency, mode, signal strength, and navigation prompts

  • A main rotary encoder for channel/frequency changes

  • Soft keys for mode, menu, and function access

  • A clear PTT and programmable side keys

Expect a learning curve the first few hours as you navigate menus and map GPS/APRS features. The Bluetooth app aims to simplify channel edits and APRS configuration; its usefulness depends heavily on the quality of the vendor app.

Audio and speaker performance
Built-in speakers on handhelds are generally sufficient for close-range listening and most outdoor use. The RT-950 PRO should deliver clear speech at normal listening volumes and adequate loudness for outdoor environments, but heavy bass or high fidelity audio is not the design objective. The included microphone will improve clarity when transmitting compared to using the on-body speaker-mic interface, and third-party speaker-mics can usually be used if the connector is standard.

Receive performance (AM/FM/CB/SW/MW/LW)
One of the RT-950 PRO’s strong selling points is its wideband receive capability. A broadband receiver allows monitoring of many services — from local AM/FM broadcasts to shortwave and longwave signals. In practice:

  • FM broadcast reception is generally reliable and clear within the local coverage area.

  • AM and MW reception depends on antenna design and noise environment; expect acceptable performance for local and regional stations.

  • Shortwave (SW) reception will allow you to pick up distant broadcasters under favorable conditions, but performance will vary with antenna and local RF noise.

  • CB/27 MHz receive should be suitable for monitoring CB traffic, weather bulletins, and nearby transmissions.

Because the radio attempts to cover many bands, it won’t beat specialized base or dedicated SDR receivers in sensitivity or selectivity, but for a handheld it provides excellent versatility.

Transmit performance, power, and range
The RT-950 PRO’s advertised 10-watt output on 27 MHz is notable because many handhelds are lower power. In open conditions, 10 watts on 27 MHz can reach significant distances, especially when propagation conditions are favorable and the antenna is efficient. Expect the following practical considerations:

  • Line-of-sight and terrain heavily influence range. Urban environments with buildings will reduce range significantly compared to open water or flat countryside.

  • Antenna quality and tuning matter. Supplied whip antennas on handhelds typically balance size with performance; aftermarket or vehicle-mounted antennas will improve effective range.

  • Legal and licensing rules vary by country and band. Transmitting on amateur bands often requires a license. Transmitting on CB or other allocated bands must follow local power and equipment rules. Always verify local regulations.

GPS, APRS, and app programming
The inclusion of GPS and APRS gives the RT-950 PRO utility beyond voice: position reporting, messaging, and location-aware features are possible when APRS is configured properly. APRS usefulness depends on integration with local digipeaters and network infrastructure.

Bluetooth app programming promises a modern convenience: instead of navigating menus on the radio, you can edit channels, save memories, and configure APRS from your phone. The overall experience will depend on how polished the vendor’s app is — a good app saves time, while a weak app can be slow or buggy. Bluetooth also enables potential audio streaming or hands-free operation if the vendor supports it.

NOAA weather and emergency use
NOAA weather reception (assuming you are in the U.S. or a region where similar meteorological broadcasts exist) is an important feature for emergency preparedness and field operations. The radio’s ability to receive continuous weather alerts can be valuable for hikers, boaters, and preppers.

Programming cable and microphone
Shipping a programming cable is helpful for users who prefer desktop editing with PC software. The included microphone is a practical accessory for handheld voice clarity. If you plan advanced configurations, check compatibility with common programming software before purchase.

Battery life and charging
Battery life depends on transmit duty cycle, power level, and whether GPS/APRS and Bluetooth are active. A typical handheld in this class might last a day of casual use or a shorter time under heavy transmit usage. Removable batteries and the ability to swap spares are beneficial for long outings. Charging via USB or a dedicated charger is common; confirm what charging method the unit supports.

Pros and cons (summary)
Pros:

Cons:

Who should consider the Radtel RT-950 PRO

  • Radio hobbyists who want a single portable unit that can receive many services and transmit on 27 MHz

  • Preppers and outdoorspeople who value NOAA weather reception and APRS location features

TYT TH-9000D — Full in-depth review


INTRODUCTION
The TYT TH-9000D is a mobile VHF transceiver aimed at amateur radio operators who want a high-power 2-meter mobile rig with flexible programming options. It promises strong transmit capability, a familiar user interface, and the convenience of USB programming. In this review I cover design and build, installation and wiring, user interface and ergonomics, receive and transmit performance, programming and software experience with the included USB cable, features and usability, audio quality, reliability and heat management, practical use cases, pros and cons, recommended accessories, and final verdict.

OVERVIEW AND WHO THIS IS FOR
The TH-9000D targets hams who use 2 meters as their primary mobile band and who value higher transmit power for extended range from a vehicle installation. It is particularly useful for operators who travel over varied terrain, need to reach distant repeaters, or run simplex between mobile and fixed stations. It also appeals to hobbyists who want straightforward USB-programming rather than manual channel entry.

DESIGN AND BUILD
Physically the unit follows a traditional mobile radio layout: a compact main head unit with a clear display and a detachable microphone. The chassis is metal and feels solid for a kitted mobile installation; mounting ears are supplied and the radio is sized to fit in a standard mobile space. The buttons and knobs are serviceable — not premium, but tactile enough for in-vehicle adjustments. The microphone is standard push-to-talk with keypad entry, which makes manual programming possible when you are away from a computer.

INSTALLATION AND WIRING
Installing the TH-9000D is a straightforward mobile-radio job. Power wiring to the vehicle battery should use an adequately sized fused feed to handle higher transmit currents at full power. Grounding the chassis to the vehicle body is important for RF performance and safety. Antenna choice and placement are critical; high power only matters if your coax and antenna can handle it and if a proper VSWR is maintained. A short run of low-loss coax and a well-mounted 2-meter mobile antenna will make the most of the radio’s output. If you are unfamiliar with soldering or RF grounding, consider professional installation to ensure good RF bonding and to avoid interference with vehicle electronics.

USER INTERFACE AND ERGONOMICS
The front panel layout is pragmatic. A rotary knob for volume and menu navigation, a separate squelch control or menu-accessible squelch, and a clear alphanumeric display are typical. Menus allow changing transmit power, setting channel names, and enabling features like tone squelch. For mobile use, the ability to lock keys and adjust backlight brightness is useful. The radio is also designed for two-way handheld-style operation from the vehicle microphone, which keeps things simple for routine comms.

RECEIVE PERFORMANCE
On receive the TH-9000D performs adequately for typical VHF mobile duties. Sensitivity is comparable to other mobile rigs in its class, pulling in local repeaters, distant beacons, and simplex signals with expected clarity when antenna and feedline are in good condition. The receiver’s selectivity and squelch characteristics are acceptable for normal mixed-traffic environments, although extremely congested repeater sites with many strong adjacent signals will always challenge any mobile receiver. Overall, expect reliable, everyday performance for contesting, nets, local nets, and casual ragchewing.

TRANSMIT PERFORMANCE
The 60-watt transmit capability is the headline feature. In practice this offers a meaningful increase in coverage compared with lower-power mobile radios, especially in hilly or fringe areas. Higher power increases current draw and heat output, so thermal considerations matter for prolonged high-power operation. The radio typically allows selecting lower power levels for everyday use, letting you balance battery load, heat, and range. Properly tuned antenna systems are essential; without a low SWR antenna and good coax, additional transmit power can be wasted or damage equipment.

PROGRAMMING AND USB EXPERIENCE
One of the TH-9000D’s conveniences is USB programming. The radio ships with a USB programming cable that plugs into the rear or front programming jack, allowing channel memories, tone settings, and other options to be edited on a computer. Programming saves time compared with manual entry and is ideal for bulk edits and organizing channel banks. The actual user experience depends on the PC software used for programming; the cable typically appears as a serial device to the computer, and programming workflows follow the usual pattern: read the radio’s memory, edit on the PC, then write back. For first-time users, it is advisable to keep a backup of the radio’s memory file before making large changes. If you plan to reprogram frequently, keep the cable and software handy.

FEATURES AND USABILITY
The TH-9000D supports conventional mobile features such as multiple memory channels, channel naming, adjustable transmit power, and tone encoding/decoding for CTCSS/DCS. If you rely on tone squelch for repeater access, the memory system makes it easy to store repeaters with their tones. Many operators will appreciate features like priority channels, scan functions, and lockable front panel keys for safe driving. If the radio includes additional conveniences like a detachable face or remote head capabilities, those are valuable for flexible mounting.

AUDIO QUALITY
Audio quality on both transmit and receive is an important area. A mobile radio’s microphone and audio processing determine how intelligible you sound over the air and how clearly incoming signals come through. The TH-9000D generally provides clear receive audio in normal conditions and a crisp transmit voice when you set proper microphone gain and use good microphone technique. If you need louder cabin audio, consider mounting the radio in a location where its speaker is not blocked, or use an external speaker if the unit supports one.

HEAT MANAGEMENT AND RELIABILITY
High-power VHF operation produces heat. The radio’s chassis and internal heatsinking should handle intermittent high-power bursts, but continuous maximum-power operation will raise internal temperatures. Ensure the radio has airflow and avoid burying it under other electronics. For reliability, keep firmware up to date if the manufacturer provides updates, and avoid operating with high SWR. Routine checks of connectors and coax integrity will prolong the unit’s life.

PRACTICAL USE CASES
The TH-9000D works well for:

  • Mobile repeater access when traveling through hilly terrain.

  • Emergency communications where extra range is beneficial.

  • Vehicle-to-vehicle simplex in rural or suburban settings.

  • Amateur radio nets where mobile participation is common.

  • Users who maintain an organized memory bank and enjoy reprogramming their radio from a laptop.

PROS

CONS

TIPS AND BEST PRACTICES

  • Use quality coax and a properly tuned 2-meter mobile antenna to make the most of the 60-watt output.

  • Fuse the power feed at the battery and use an adequately sized wire to prevent voltage drop under high transmit current.

  • If you plan on frequent high-power transmissions, ensure the radio has ventilation and avoid enclosed mounting spaces.

  • Keep a programming backup file on your computer and save copies after major edits.

  • Adjust microphone gain so transmitted audio is loud and clear without distortion; test with a friendly local operator to fine-tune settings.

  • Periodically check connectors and the antenna mount for corrosion or looseness, especially if you drive through wet or salty environments.

RECOMMENDED ACCESSORIES

The Magic of HF Ham Radio: Why It's Special and How It Works

 

Introduction to HF Ham Radio

High Frequency (HF) ham radio is a cornerstone of amateur radio, providing long-distance communication capabilities that transcend geographical barriers. Operating in the HF spectrum (3 to 30 MHz), this segment of radio frequencies allows operators to make contacts across continents, facilitating emergency communications, experimentation, and worldwide friendships.

HF radio communication is crucial in a variety of applications, including disaster response, remote communication, and international networking. Unlike local Very High Frequency (VHF) and Ultra High Frequency (UHF) bands, which rely on line-of-sight propagation, HF waves can travel thousands of miles by bouncing off the Earth's ionosphere. This unique characteristic makes HF one of the most special and fascinating aspects of ham radio.

How HF Radio Works

The secret behind HF radio’s long-distance communication lies in its interaction with the Earth's ionosphere. When an HF signal is transmitted, it travels upward into the atmosphere, where it encounters ionized layers of gases at altitudes ranging from 30 to 600 miles above the Earth’s surface. These layers, known as the D, E, and F layers, reflect or refract the signals back down to Earth, a phenomenon called skywave propagation.

Skywave propagation enables signals to “skip” around the globe, making it possible for an operator in North America to talk to someone in Europe, Asia, or even Australia. The effectiveness of this propagation depends on factors such as solar activity, time of day, and frequency selection. For example:

  • Daytime: Higher frequencies (above 14 MHz, such as 20 meters and 10 meters) tend to propagate better.

  • Nighttime: Lower frequencies (below 10 MHz, such as 40 meters and 80 meters) become more effective.

  • Solar Cycle: During periods of high solar activity, HF propagation improves significantly, allowing for stronger and more consistent long-distance communications.

Why HF is Special

1. Global Communication Without the Internet or Satellites

One of the most compelling aspects of HF ham radio is its ability to establish worldwide communication without relying on modern infrastructure like the internet or satellites. This makes HF indispensable during natural disasters when traditional communication networks fail.

2. Emergency and Disaster Preparedness

HF radio is a critical tool for emergency responders and amateur radio operators who provide communications when cell towers, power grids, and internet services are down. Organizations like the Amateur Radio Emergency Service (ARES) and the Radio Amateur Civil Emergency Service (RACES) rely on HF to coordinate disaster relief efforts over vast distances.

3. DXing and Contesting

HF bands are the home of DXing (long-distance communication) and radio contests. DXing is a popular pursuit among hams who aim to make contacts with as many different countries as possible. Special events, contests, and awards, such as the DX Century Club (DXCC), motivate operators to refine their skills and improve their station setups.

4. Experimentation and Technical Learning

HF offers opportunities for amateur radio operators to experiment with antennas, modes of operation, and propagation techniques. Many hams build and test antennas tailored for specific HF bands, helping them optimize performance for long-range contacts.

5. Modes of Operation

HF radio supports a variety of communication modes, including:

  • Single Sideband (SSB) Voice: The primary mode for voice communication, providing an efficient use of bandwidth.

  • Morse Code (CW): Still popular among many hams, CW is highly efficient and can penetrate weak signal conditions.

  • Digital Modes (FT8, PSK31, RTTY): These modes use computer-assisted transmission to decode weak signals and allow for efficient, low-power communication worldwide.

Licensing: The Need for a General or Extra Class License

To access the HF bands, a ham operator must obtain a General Class or Extra Class license. The entry-level Technician Class license primarily grants privileges on the VHF and UHF bands, with very limited HF access. Upgrading to General Class opens up a significant portion of the HF spectrum, while Extra Class offers full privileges across all HF bands.

Why Upgrade to General or Extra Class?

  1. More Frequencies, More DX Contacts: General Class operators gain access to most HF bands, allowing them to communicate globally.

  2. Participation in DX Contests and Special Events: Many international stations operate on frequencies reserved for General or Extra Class license holders.

  3. Emergency Preparedness: Having HF privileges ensures that operators can assist in emergency communications over long distances when needed.

  4. Technical Growth: Studying for the General or Extra exam deepens an operator’s understanding of radio theory, antenna design, and propagation science.

Conclusion

HF ham radio is a truly special aspect of amateur radio, providing a window to the world through long-distance communication. Whether for emergency preparedness, technical experimentation, or simply the thrill of talking to someone thousands of miles away, HF bands offer an unparalleled experience.

For those new to amateur radio, upgrading to General Class is a key step toward unlocking the full potential of HF communication. With a little study and practice, any ham can join the ranks of worldwide communicators and experience the magic of HF radio firsthand.
