Paul Reviews the Radtel RT-880G

Looking for a versatile radio?

Which radio listener hasn’t dreamed of owning a portable multi-band receiver allowing them to explore the widest possible radio spectrum?

For nearly a year now, walkie-talkies have appeared on the market which, beyond the classic VHF–UHF functions, also allow listening and transmitting on CB (27 MHz) as well as listening to LW/MW/SW bands (LSB/USB/CW). The RADTEL RT-860 has won over those who have tested it.

Read here: Dan Reviews the Radel RT-860

The arrival of the Quansheng TK-11 — available in three versions — has caused quite a stir on social networks. Then, almost at the same time, the RADTEL RT-880 and RT-880G (G for GPS) appeared, also sold under other names such as iRadio UV98.

Among all these available models, I chose — as a radio listener, especially when I’m traveling — the RADTEL RT-880G. My choice is explained mainly by its antenna connectors (SMA-Female and SMA-Male), its large color display, its GPS module, its thousand memory channels, and the possibility of simultaneously monitoring three VHF/UHF frequencies. This device is highly customizable, but its user manual would deserve to be much more detailed and explicit.

The RT-880G comes with a “standard” 18 cm antenna for VHF-UHF bands, which is also used for FM station reception. I haven’t yet tested the device on the 27 MHz (CB) band, for which a dedicated antenna is preferable. No antenna is provided for LW/MW/SW listening.

For listening to LW/MW/SW bands, the device is often shown with small donut-type loop antennas (10 cm diameter).

However, for easier transport, I simply chose this small telescopic SMA-Male antenna, 48 cm long (weight: 20 g): to which it is possible to clip a wire antenna, such as the SONY AN-71, which can prove very useful.

I also used an antenna normally intended for CB, the ABBREE 27 MHz telescopic antenna (130 cm), admittedly heavier (weight: 78 g) and bulkier, but which gives very good results for the HF band.

The purpose of this contribution — which concerns only listening — is to arouse curiosity among mobile (or stationary) listeners, to invite those who own this walkie-talkie to come here and share their experience, and to collect your comments. It is therefore not a full review of the RT-880G, but simply an illustration of what it offers for listening to LW/MW/SW bands.

For LW/MW/SW bands, the RT-880G allows you to set the:

step to 1 – 5 – 10 – 50 – 100 – 500 – 1,000 – and 9 kHz],
bandwidth [0.5 – 1.0 – 1.2 – 2.2 – 3.0 – 4.0],
AGC (Automatic Gain Control)
BFO – (Beat Frequency Oscillator) – used for fine tuning SSB reception (the minimum step being 1 kHz).

Sample Recordings

WT2 Mini Handheld With Everything Radio

by Michael Ye (BD4AAQ)

What Exactly Is the WT2?

No exaggeration. The WT2, a recent radio developed by Choyong, includes nearly every type of radio imaginable: ham radio, traditional shortwave and medium-wave radio, internet radio and, last but not least, push-to-talk over cellular radio!

The radio is powered by the TEF6686 chip, which has an excellent track record in high-performance radios. This suggests the WT2’s performance will surpass that of the highly regarded LC90. Packing so many features into a handheld device would have been unimaginable a decade ago without state-of-the-art technology and the internet.

I’m fortunate to be among the first to get my hands on the WT2. I’d seen its picture before but was still pleasantly surprised when I unboxed the real thing and saw its actual size. The picture below shows my iPhone 12 Pro next to it for comparison. At this small size, it fits sleekly into one’s pocket. I’ve always wanted a radio to listen to while walking or jogging. Now, I have one.

Continued Success of Choyong Radio Receivers

As a young and innovative technology company, Choyong was the first to launch a radio receiver combining traditional radio with internet radio: the LC90. The LC90 has been a resounding success. An improved version, the LC95, has been launched domestically in China. Rumours suggest that the LC100 is in development to build on the success of the LC90 and LC95.

Now, powered by the TEF6686 chip, the WT2 delivers even greater sensitivity and selectivity. Its unique combination of multiple radio types in a single, compact handheld form factor makes it highly competitive. In fact, I’m unaware of any other radio that packs so many features into such a sleek design. The young team at Choyong boldly leads the way, fearlessly testing the market waters.

Internet Radio

Choyong has confirmed that the WT2, like the LC90, will be available in both export and Chinese versions.

“In terms of the stations that can be heard, the internet radio exhibits significant differences from that of the Chinese version. The Chinese version is designed to exclusively feature Chinese language stations (and a few English language stations) in China. If we liken the Chinese internet radio to a closed system such as iOS, it is stable, reliable but restrictive. In contrast, the export version could be compared to Android, offering more open, inclusive and customisable user experience.

On the export version, the MENU button provides access to the main menu, which begins with the six continents (excluding Antarctica) and allows users to navigate to the desired country and then select a specific station.”

The WT2 supports Wi-Fi for indoor use and comes with a built-in eSIM for 4G cellular connectivity. This allows you to easily carry the WT2 in hand or slip it into a pocket, making it ideal for listening to internet radio while walking or jogging.

Traditional Radio

Shortwave performance is impressive, especially considering the small antenna. Surprisingly, the 13.6cm walkie-talkie antenna extends to a full 48cm. This significantly improves shortwave reception, as well as FM reception. Unfortunately, the WT2 lacks SSB demodulation on shortwave, which is a bit disappointing.

Medium-wave reception is poor with the receiver’s whip antenna. Indeed, what can you expect from a whip antenna without a ferrite bar? However, I experimented by connecting a longer wire to the antenna’s SMA connector, and MW reception improved remarkably, much to my surprise.

Arguably, the WT2’s FM reception is outstanding. I compared this compact radio with various others, large and small, old and new, and the WT2’s FM performance is simply the best. Its sensitivity generally surpasses that of competing models, allowing me to receive stations that were inaudible on others. A prime example is Shanghai’s Classic Music Channel on 94.7 MHz, which many report as having medium to weak signal strength. Yet, the WT2 pulled it in with exceptional clarity, free of the occasional hissing I noticed on other radios.

Ham Radio and Walkie-Talkie

Amateur radio operators will appreciate the WT2, as it covers the standard Ultra High Frequency (UHF) amateur band, with a maximum transmitting power of 2 watts. It also includes the FRS/GMRS bands (not for use in China). The Very High Frequency (VHF) band is expected in future models.

Caution: When transmitting with the WT2, retract the extended antenna to avoid damaging the device.

Although the WT2 is a compact handheld, it includes features found in other walkie-talkies, such as squelch, tone squelch and scanning, all packed into this sleek device.

PoC Talking

Push-to-talk over cellular (PoC) is not new, but it has gained popularity in recent years with the rise of 4G and 5G mobile communications.

A decade ago, taxi drivers in Shanghai used traditional walkie-talkies to communicate within their network for vehicle dispatch or casual rag-chewing. Some were radio amateurs, but I suspect others were not and were thus operating illegally without a proper license. Years later, most of them, if not all, had switched to PoC, a modern method offering legal communication with crystal-clear audio and virtually no distance limitations.

I gave it a try, and of all the people who could have answered, it was BA8BM, a fellow ham in Sichuan, China. Needless to say, the audio was excellent!

With the WT2, users can create as many groups as they like, each supporting up to 10,000 members!

Other Features

The WT2 features a TF card slot that accepts cards with a maximum capacity of 32 GB. This storage can be used for playing music or serving as an external data drive.

The Bluetooth connection supports internet radio but not traditional radio. I successfully connected my AirPods and Bose headphones. They work well for internet radio but by design not for traditional radio.

The WT2 is equipped with a 2,500 mAh rechargeable lithium battery. Unlike the LC90, the battery is not user-replaceable. For a lightweight radio like the WT2, I’d say 2,500 mAh is sufficient for most daily use.

Key Takeaways

The WT2 is a remarkable compact radio that combines traditional and modern radio technologies. It features a 240×283 mini screen with a vibrant, high-quality colour display that’s truly impressive. The extendable antenna enhances shortwave and FM reception. The audio is crisp and clear but slightly soft. Bluetooth supports internet radio but does not work with traditional radio.

With its four-in-one radio capabilities, users can communicate or listen however they prefer. Want to make a CQ call with a fellow ham? You have amateur radio. Craving crystal-clear conversation? PoC is available. Feel like tuning into nostalgic, sometimes noisy broadcasts over the airwaves? Shortwave, medium-wave, and FM are ready. Eager to explore internet-based radio? There’s a wealth of stations from across the country or around the world.

The WT2 is much smaller (though slightly thicker) than an iPhone and can be used handheld or, via Bluetooth, slipped into a pocket for walking or jogging.

The WT2 has a voice assistant to help you navigate its internet radio and other features with ease.

A versatile little gadget for radio hams, shortwave listeners (despite lacking SSB), and broadcast listeners alike!

Data modes using DIY interface using the built-in VOX system

What you will need for QT80 – There are not many parts needed to get our own data-cable prepared.

– For the connection to the Radioddity QT80 you will need a 6-pin GX16-A6P plug, often called “aviation plug”.
– For the connection to your PC, you will either need a shielded stereo audio-cable with 3.5mm TRS plugs on both ends or two shielded open end stereo audio cables with 3.5mm TRS plug.
– If your PC does not have a built-in sound-card you will also need a USB soundcard with 3.5mm TRS sockets for MIC-in and Audio-out.

__________________________________________________________________________

I have included above some recently released information about how to use the radio for TX and RX with digital modes such as FT8/FT4 and SSTV, PSK etc.

While not indicated as such on the Radioddity website, the radio is capable of going down to 15 meters with a slight modification, demonstrated by some of the YouTube videos, which also includes the 11- and 13-meter bands.

Internal main PC board and large speaker

Additionally, Radioddity offers a Model CBL-561 15-30mHz vertical antenna option which can be attached to a mobile mount by way of its PL-259 connector. My sample copy of the antenna is extremely sturdy, and has an adjustable whip section for matching the chosen band.

My Impressions

The radio is well-built, solid, and has a heavy heatsink for handling the 80-watt output power, as there is no built-in fan. There are a number of nice features in the radio, including multiple color screen options, VFO tuning and scanning features down to 1 kHz, and very usable noise reduction and clarifier options. There is also a PA function which could come in very handy for emergency response situations.

The speaker is quite capable of being heard even with loud road noise, but due to the speaker placement on the bottom of the radio, where you have to mount the radio in your particular setting might determine if you need an external speaker.

The audio quality is quite good as I listened around to stations on 10m USB and 11m CB, as well as shortwave signals.

The noise reduction feature is designed to filter out unwanted noise on receive of course, but is also designed to work on the TX side of things to help with voice clarity. While the primary goal is clarity, if possible, I would recommend testing the TX side of things with someone who is familiar with your voice so you can adjust the noise reduction levels more accurately.

There is a USB connection which allows for firmware upgrades, programming capabilities, and, with some DIY effort, TX for Digital modes.

VFO Tuning vs. Channel Hopping

The QT80 offers both a channelized scan and tuning feature, as well as a scan and VFO option. Scanning/tuning of channels is as you would expect, allowing you to scan through 40 programmed channels, or 99 memory channels.

Scanning using the VFO method allows you to scan in various steps of 10 kHz or above. It should be noted that to tune to a level of 10 or 100 Hz accuracy, this must be adjusted by pressing the tuning dial in, which then allows you to select these tuning steps. For all automatic and manual tuning of frequencies using the tuning dial, the smallest step is 1 kHz. That can be a little confusing for those who are used to free turning VFOs on desktop/portable receivers.

As the tuning dial/channel switch (the big dial on the right-hand side of the unit) is designed primarily for channel selection and incremental tuning, there is both muting and an audible click as the dial is turned.

As the radio is clearly designed for mobile-style operation, the memory channels can easily be used to store 10-meter repeater stations (along with the necessary offsets), CB channels, as well as storing simplex frequencies to quickly tune in desired frequencies for scheds with other amateur radio operators.

The freely available programming software allows for easy programming of memories and channels, as well as controlling most all of the radio’s functions.

As you can see in the image below, the microphone has up and down buttons for tuning, as well as a PF button which can be assigned for specific programmed functions. The mic does not have a keypad, a nice, but not necessary function. As an aside, I have not seen any data as to what microphones might be interchangeable with the stock mic, so I would certainly do extensive research before trying a keypad-style mic with the radio.

Receiving California QSO Party signals clearly

Pros and Cons

Pros

Advanced features such as noise reduction and receive clarifier
A reasonable number of memories which don’t get ridiculous in size like some radios (i.e. 1000 memories!)
Simplified front end with menu options (see also Cons)
Feature-Rich radio beyond many similar mobile radios (see Cons below)
Multiple color options for the screen to enhance viewing in different lighting conditions
Large heatsink
Capability to store 10m repeater stations in memory with offset info
Great audio
Ability to work digital modes using the built-in VOX capabilities with DIY solution, no separate sound interface needed
CW TX possible with DIY solution shown on website
Free programming software
Standard antenna connections giving many antenna/tuner options

Cons

Bottom-mounted speaker (common, but not good if mounted near floor or in compartment) but external speaker port available
Non-removeable front-end, useful for more localized placement/ease of operation in vehicle or tight spaces
Many special functions require menu options which make mobile operation more difficult or dangerous when driving
Fairly steep learning curve to take advantage of all the features (see Pros above)

Conclusions

I believe most folks will be very pleased with the advanced capabilities of this rig. There is a bit of a learning curve for those who may not have used this style of radio before, but the time spent learning its features so as to make use of all these features will be well rewarded.

The radio has excellent audio, a clear display, many adjustments to make the radio function as desired, and has expansive capabilities to broaden its appeal. 73, Robert K4PKM
