New Reuter Elektronik RDR52 QRP general coverage transceiver

Many thanks to SWLing Post contributor, Dave Zantow, who notes that Reuter Elektronik recently introduced their latest radio: the RDR52 QRP Transceiver.

Here’s the announcement from the Reuter Elektronik website:

RDR52 in standard “black” and special “metal”

The RDR52 can basically be seen as a desktop version of the popular Reuter Pocket mobile device. Astonishingly, the Pocket is often used as a full-fledged desktop receiver. Many operators report that they have sold their “large” devices and now only use the Pocket because it pairs good reception properties with simple operation and offers a very effective spectrum display while keeping the power consumption to a minimum.

However, the battery-powered Pocket was never designed for that purpose. First, it needs a stand-up aid to be easy to operate on your desktop (display almost vertical). Second, the playback volume of the loudspeakers is low and turning the scroll wheel feels finicky. Third, operation on a constant charging current supply is suboptimal for the built-in batteries: Constant full charging shortens their service life.

The RDR52 avoids these disadvantages. It essentially contains the circuit and thus the display and reception properties as well as the operating options of the Pocket. Due to the larger housing (heat dissipation) and a slightly higher possible current consumption (no batteries as power supply), improvements in the IM behavior (more powerful preamplifiers and AD converters) could be achieved. Other differences to the Pocket include:

- Aluminum profile housing 190 x 90 x 100 mm³ with 5 mm thick front and 2 mm thick rear panel, powder-coated / anodized.
- BNC sockets for antenna connection, separate for 0 – 71 MHz, FM / 2m / DAB and exciter / QRP transmitter.
- Large rotary knob with solid optical rotary encoder.
- Additional rotary knob for volume adjustment of headphones and loudspeakers.
- Two 32 mm loudspeakers with good bass reproduction.
- External power supply DC voltage 9 – 15 V (common hollow pin socket with 2.5 mm pin).

All the Pocket’s enhancements are also available for the RDR52 (broadband spectrum with up to 52.6 MHz display width, 8 different FM filters for extreme DX to high-end stereo, up to 16 GBit flash memory for audio or I/Q recordings, screen dump of the display to the recorder, WiFi, Bluetooth, power supply and control of the RLA4 / RFA1 directly from the antenna input, …). Two basic hardware versions will be available: Standard black with simple loudspeakers and plastic knobs, or a special version with metal knobs and aluminum loudspeaker membranes.

The equipment of different transmitter modules and frequency ranges has been a bit expanded in contrast to the Pocket. Two modules can be installed in the RDR52 at the same time (Pocket: only 1 module). This means, for example, that the FM module and the SW QRP transmitter can be installed at the same time, or the broadband exciter can be installed without the need for an FM module. However, equipping both transmitter modules (exciter and QRP transmitter at the same time) is not possible.

The RDR52 is in production and is expected to be available from the end of December 2021. Prices according to the current price list.

Based on the price list, it appears the RDR52 will start at € 999 with a number of optional upgrades/configurations.

17th Edition of the Global Radio Guide (Winter 2021-22) Now Available

On any given day, the People’s Republic of China (PRC) fueled by a meteoric rise in the country’s economics, politics, the covid pandemic, cyber security and human rights issues, Beijing Winter 2022 Olympics, and a strident expansion of the country’s military forces dominates global news headlines and news cycles. These headlines include China’s recent tensions with Taiwan, which are said to be the worst in forty years, and its other neighbors in the South China Sea region.

As China’s influence continues to expand worldwide, so have the country’s huge radio broadcast services. Local, regional, and international mediumwave and shortwave networks carry news and programming to audiences around the world. Since these services are government-sponsored you are hearing China’s Communist Party’s (CCP) perspective of worldwide events as they unfold. Topping the list of the country’s media outlets is China Radio International (CRI) the largest and most widely heard station in China.

For those who want to follow all the ongoing storylines originating from the PRC, Gayle Van Horn’s 17th Edition of her Amazon bestselling Global Radio Guide (Winter 2021-22) has all the details you need to monitor all the radio services from the Land of the Red Dragon.

Her feature is one of the most comprehensive articles ever written on the Chinese radio broadcast system. Complete schedules for all China radio services, a section of how to ID national stations broadcasting in Chinese, and links to videos with CRI IDs in 45 languages on the author’s YouTube channel that are just some of the materials you will find in this all-important cover story in the GRG. This is an indispensable guide to for the radio listener to hear China as tensions in the region continue to heat up.

China’s broadcasters are not the only focus of this completely updated edition of the GRG, though. Worldwide, tensions are continuing to escalate, and – in another case of what is old becoming new – people around the world are once again turning to shortwave radio to place themselves on the front lines.

With the help of the GRG, you can tune in to shortwave broadcast stations from other hotspots such as Cuba, India, Iran, North/South Korea, Taiwan, Hong Kong, and many other counties. If you have a shortwave radio receiver, SDR or Internet connection, pair it with this unique radio resource to know when and where to listen to the world.

This newest edition of the GRG carries on the tradition of those before it with an in-depth, 24-hour station/frequency guide with schedules for selected AM band, longwave, and shortwave radio stations. This unique resource is the only radio publication that lists by-hour schedules that include all language services, frequencies, and world target areas for over 500 stations worldwide. The schedules included in this edition of the GRG are valid from 31 October 2021 until 26 March 2022, the B21 broadcast schedule period.

The GRG includes listings of DX radio programs and Internet website addresses for many of the stations in the book. There are also entries for time and frequency stations as well as some of the more “intriguing” transmissions one can find on the shortwave radio bands.

Gayle has also updated her now-famous SDR Buyer’s Guide, a must-have compendium that helps you navigate through the revolutionary world of software-defined radios (SDRs), the new digital frontier of the radio hobby.

Also new in this 17th edition, James Careless, in an article that originally appeared in Radio World, looks at the current state of shortwave receiver technology. Dr. Adrian Peterson of AWR looks back at the early days of Philippine broadcasting. David Harris has written a review of the bhi NES10-2MK4 Noise Cancelling Speaker. Spectrum Monitor columnist Fred Waterer will take you on a guided tour of shortwave music programs from around the world.

There are updated columns including the latest radio news in Bits & Bytes, current radio QSL information and addresses, the Best of the Best DX shortwave program listings, and a listing of radio station Internet websites.

This edition also has introductory articles for beginners on Traveling the World via Shortwave Radio Broadcasts, Monitoring the Shortwave Action Bands, and Teak’s latest greatly expanded frequency list of HF non-broadcast radio stations worldwide.

Global Radio listeners are routinely entertained with unique perspectives to events, music, culture, history, and news from other countries that you will not see or hear on your local or national broadcast channels. Global Radio broadcasts are not restricted by country borders or oceans and can travel thousands of miles, reaching millions of listeners worldwide, now in over 300 different languages and dialects.

Whether you monitor shortwave radio broadcasts, amateur radio operators, or aeronautical, maritime, government, or military communications in the HF radio spectrum, this book has the frequencies to help you to hear it all. Teak Publishing’s Global Radio Guide “brings the world to you.”

The new Winradio WR-G69DDCe ‘Artemis’ wide bandwidth SDR

7 Replies

Image: WinRadio

WinRadio has just added a new SDR to their line-up: the Winradio WR-G69DDCe ‘Artemis’.

In the spirit of WinRadio’s approach to iterative design, the Artemis appears to be their new flagship SDR. The specs and features (see below) are impressive.

The WR-G69DDCe has two (selectable, I assume) frequency ranges. In “Range 1” it operates as a direct sampling SDR from 8 kHz to 80 MHz. In “Range 2” it operates as a superheterodyne receiver from 43 MHz to 8 GHz.

It appears the WR-G69DDCe’s recording and processing bandwidth is an impressive 32 MHz. I imagine it would take some proper CPU horsepower and a large, speedy SSD to make those 32 MHz recordings!

At time of posting, I haven’t seen details about pricing and availability, but I’m 99% certain this will not be a budget model. WinRadio’s higher performance SDR models have historically retailed in excess of $2,000 US.

The following details were taken directly from the Winradio WR-G69DDCe product page:

Overview

The WiNRADiO WR-G69DDC ‘Artemis’ is a top performance, software-defined, wide-band, ultra-fast search speed 3 GHz/s, HF/VHF/UHF/SHF receiver. Two independent and mutually exclusive inputs are provided, one for each range: 8 kHz to 80 MHz and 43 MHz to 8 GHz. A real-time 80/34 MHz-wide spectrum analyzer is included with a 32 MHz wide instantaneous bandwidth available for recording, demodulation and further digital processing over the whole frequency range.

The receiver’s superior performance results from its innovative, combination of direct-sampling and superheterodyne, digital down-conversion architecture along with the use of leading-edge components and design concepts. These all result in excellent sensitivity, phase noise and dynamic range, highly accurate and stable tuning, high scanning speed and perfect demodulation. These key features create a receiver in a class of its own, making it capable of filling not only the role of a monitoring receiver but also that of a fast search receiver and measuring receiver, with many operational and instrumentation features not usually found on receivers of any price category.

The entire 32 MHz DDC (digitally down-converted) bandwidth is available for recording and demodulation, and ideal for hopping frequencies analysis. Three demodulators allow the simultaneous reception and decoding of radio signals within the entire band.

The WR-G69DDCe also features optional external reference frequency inputs and outputs as well as 1PPS pulse input. In addition, stereo analog output is also possible, as well as wide audio (10 Hz-150 kHz). The special data port offers numerous possibilities which include GPIO (general purpose I/O), HSP (high speed data output), or traditional RS232 interface.

Features

- 8 kHz to 8 GHz frequency range
- Direct sampling & superheterodyne
- Digital down-conversion
- 16-bit 200 MSPS A/D converter
- 80/34 MHz-wide, real-time spectrum analyzer
- 32 MHz recording and processing bandwidth
- Continuously adjustable filter bandwidth down to 1 Hz
- Waterfall display functions and audio spectrum analyzer
- Audio and IF recording and playback
- Recording with pre-buffering
- Ultra-fast search speed 3 GHz/s
- High sensitivity
- Excellent dynamic range
- Excellent frequency stability (0.1 ppm)
- Test and measurement functions
- Networking version of application software available
- USB 3.0 and 1 Gb Ethernet (with PoE) data interfaces
- Numerous data and signal hw options
- Self-diagnostics with BIT and thermal management
- The receiver interfaces to a Windows-compatible PC via USB 3.0, or 1 Gb Ethernet LAN port with PoE (Power over Ethernet functionality according to the IEEE 802.3at standard).

For the highest bandwidth use, connection is best via USB3 for short distances (up to 3m). As the G69DDCe is equipped with an Ethernet socket, semi-remote connection to a computer is possible via a long Ethernet cable (up to 100m in length). For longer distances or when located in a busy or remote network, the Networking CSO option is recommended.

The receiver is very well shielded against interference, making it possible to operate in a noisy computer environment. Its modest power requirements are less than 20 watts. While connected via a LAN interface, thanks to PoE built-in functionality, the receiver can be operated and powered via a long Ethernet cable connection.

I’ll post information about pricing and availability once it’s available. Stay tuned!

Many thanks to SWLing Post contributor, Frank, who shares the following:

Hello Thomas,

HanRongDa has built a new mini portbale called HRD-700. Information of it is still rare, and of course it is not a professional radio. But it is interesting as it is a special analogue tuner with digital background.

I have bought one and i am really estonished about its reception quality and features. Very small, so good for camping…

Actually nowhere a manual can be found on the internet, but I have got an English document and I scanned it to share here. Perhaps it is interesting for some readers?

Friendly regards

Frank from Germany

What an interesting radio design! We hope you report on the performance and share your thoughts soon, Frank! Thank you for the English manual!

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post and review:

CountyComm GP7 / Tecsun PL-368: Is It All You Need?

by Dan Robinson

It’s been a long wait, but CountyComm, that supplier of all kinds of neat and useful stuff, finally released the GP7 SSB (Gen 4).

As the name states this is the 4th generation of the series of radios adapted by the company from the Tecsun PL-36xxx series of receivers (there was at one point a GP6 that was a never-released special project).

All photos by CountyComm

This walkie-talkie style, though receive-only, portable has undoubtedly been a big seller for CountyComm since the first model came out. It’s popular not only with SWLs and amateur operators but also with preppers.

When OEM Tecsun finally did what everyone was clamoring for – redesign the radio with a keypad and including features associated with the PL-880/330/990x/501x receivers – the ground shook. Continue reading →

HFDY vs. Fire Brothers: Dan compares two Chinese Malahit SDR clones

10 Replies

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post and review:

Two Chinese Clones: A Look at Noise Levels

Arriving recently here in the radio shack, were a Chinese clone under the name of “Fire Brothers” and another under the name HFDY. I thought it would be constructive to note the key differences between these two clones, both of which are running Malahit 1.10c firmware, and post some video of a brief comparison.

A note in advance of any comments – I am primarily a HF listener so these comparisons do not cover frequencies above 30 MHz. For those whose focus is on higher frequencies I recommend looking through the many comments on the Malahit Facebook group and Telegram by those who use these receivers in those ranges.

HFDY

Constructed of metal-like material (a correction from my previous articles that this is fiberglass of the kind used in printed circuit boards – thanks to Georgiy of Malahiteam for pointing this out)
Front speaker grille is gold color and appears to be metal but may be fiberglass as well – audio is quite good
Two top-mounted antenna jacks, one 50 ohm, the other Hi-Z (makes switching between HF and FM/VHF reception easier) with in-use LED indicators
Two high quality right side mounted black metal encoder knobs with large power button (clear printed Frequency/STDBY/Volume printed on panel)
Cabinet held together with TORX screws
1.10c firmware
Receiver is elongated left to right to accommodate left side front-firing speaker, but is thinner overall and could be easily placed in a pocket though not recommended to prevent damage
Like every one of these SDRs, suffers from body sensitivity to touch which reduces signal levels unless some sort of additional ground is attached to cabinet
Internal flat-type Lithium battery of 3300 mAh though apparently capable of fitting up to 8000 mAh
