Quick Look: the RADIWOW R-108, a new DSP shortwave portable

Last week, I received a new portable shortwave radio by the post from China: the Radiwow R-108.

The brand, Radiwow, was new to me, but I suspect they’re linked in some way to the folks behind XHDATA. They contacted me around the Thanksgiving holiday and inquired about evaluating this new portable receiver. I replied, asking a few questions about the unit–you see, I don’t typically agree to take a look at a new product if I think it could simply be a re-badged version of something currently on the market.

Their reply was simple:

“Yes, it is shortwave radio, like PL-310ET radio but add air band, and better reception performance. Your tracking number is…”

So evidently, it was already on the way.

Radiwow claims the performance is better than that of the venerable Tecsun PL-310ET. This, I will have to test because the PL-310ET is certainly a workhorse Ultralight radio. And the R-108 includes air band? Sounds like a CC Skywave without weather radio. That could be quite appealing if the price is competitive.

And it seems this little radio fits neatly into the requirements of Ultralight DXing, thus I hope Gary DeBock and Guy Atkins might take a look as well.

In addition, the R-108 includes longwave frequencies. Something I know will please a number of our readers.

Here are some of the key points I gleamed from a digital copy of the owner’s manual:

Radiwow R108 Features:

Frequency range:
- Longwave: 150-450 kHz)
- Mediumwave/AM: 520-1710 kHz w/10 kHz steps, 522-1620 kHz w/9kHz steps
- Shortwave: 1711-29,999 kHz
- FM: 87.5-108 and 64-108 MHz
- AIR: 118-137 MHz
ATS memory scans on all bands
500 available preset memories
Squelch control
Direct keypad entry of frequencies
Clock function with sleep timer, snooze and alarm (buzzer or radio)
Keylock
FM stereo
AM bandwidths: 6, 4, 3, 2, and 1 kHz selections
Music/Voice audio modes
Built-in intelligent charger for included 3.7V 1500 mAh Li-ion battery pack

By the way, I suspect Radiwow is linked to XHDATA because 1.) they knew my shipping address without asking and 2.) their website prominently features the XHDATA D-808.

In addition, the only other place I could find the R-108 listed on the Internet is via AliExpress. As with the introduction of the XHDATA D-808, the AliExress price is (today) absurdly high. To me, this indicates that the page is simply a placeholder until the first production run is ready to ship.

I have a PL-310ET and you can count on me to compare the two sometime after the holidays.

In the meantime, I thought I’d share a few photos of the unit.

I must admit, the front panel of the radio looks familiar, but perhaps only because most other DSP portables have a similar layout. Please comment if you know of an identical portable.

WRTH 2019: A look inside

12 Replies

I received my copy of the 2019 World Radio and TV Handbook (WRTH) directly from the publisher earlier this week. It arrives annually–without fail–just prior to my Christmas holiday travels.

I look forward to receiving this excellent staple radio reference guide–and this is their 73rd edition! The WRTH has never disappointed, so my expectations are always quite high.

Once again, the WRTH lived up to my expectations.

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

The first article always features a WRTH contributor: this year, they feature Kai Ludwig who is their contributor for Germany. His lifelong passion for international broadcasting started in what was then East Germany–he watched with interest as the broadcasting world change around him as the Iron Curtain fell.

The second set of articles is always my favorite: WRTH receiver reviews.

The AirSpy HF+ SDR

This year, WRTH begins with a review of the WinRadio Excalibur Sigma SDR receiver–which essentially set a new benchmark. They also review the SDRplay RSPduo, AirSpy HF+ (which truly impressed), the Reuter RDR51 “Pocket” SDR, XHDATA D-808 and the new Icom IC-R30 wideband handheld. What I love about the WRTH review selection is they span products ranging from £70 all the way up to £6200! Certainly, choices for everyone.

The next feature article, written by none other than Dave Porter, focuses on curtain antennas–the true work horses of international broadcasting. His article speaks to the history and theory behind curtains and notes several types often used by international broadcasters. A must-read!

Hans Johnson’s feature, Broadcasting For Peace, tells the inspiring story of how two stations with one mission helped promote peace in a troubled region of Africa. It truly is amazing how these stations gave their listeners a voice and hope.

The following article highlights a broadcaster on the opposite side of the globe: V7AB in the Marshall Islands. For this feature, journalist Mika Mäkeläinen traveled to the Marshall Islands and visited this powerful national AM broadcaster.

Speaking of powerful broadcasters, TWR Broadcast Engineer, Dave Pedersen, authors an article outlining the reasons for and challenges of operating and maintaining TWR’s Bonaire MW transmitting station.

Next, WRTH spotlight the annual Digital Update which summarizes the dynamic state of digital broadcasting. I’ve found this feature to be incredibly informative as we see how digital broadcasting is penetrating both domestic and international services.

The final article–a tradition–is the WRTH HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read despite the fact we’re in a solar low!

The 73rd is another fantastic edition of the World Radio TV Handbook. As I say every year, I’ve never been disappointed with WRTH. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2019 directly from WRTH’s publishers, or from a distributor like Universal Radio (US), Amazon.com (US), Radio HF (Canada), or check BookDepository.com (International).

Alexa can now look up broadcast schedules with the Shortwave Signals skill!

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

I’m pleased to announce that my Alexa skill has been approved by Amazon and is now available in the following countries:

Australia, Canada, the United States, and the United Kingdom.

Because single word skills are reserved for organisations and brand names, the skill name had to change and is now called ‘Shortwave Signals‘.

I’ve uploaded a video this morning with the finished skill in action:

Click here to view on YouTube.

Amazing, Mark! Thank you for developing this Alexa skill!

I’ve been beta testing Mark’s Alexa skill and have been very happy with the results. It makes for a nice hands-free way of checking broadcast schedules while in the shack. And it seems like only yesterday when Mark was tinkering around with the idea to create this skill.

Bravo for making Shortwave Signals a reality, Mark!

If you own an Echo or Alexa-enabled device, simply open the Alexa App and search for the Shortwave Signals skill to activate it.

We only have one Amazon Echo device in our house–the one I evaluated for my WiFi radio primer a couple years ago. As Black Friday approaches, I’m going to keep my eye on the Amazon Echo Dot for my radio room–the 2nd generation units are quite inexpensive (as low as $29.99 for a certified refurbished unit).

DXtreme Station Log 14

Product Announcement DXtreme Station Log 14

DXtreme SoftwareTM has released a new version of its popular logging program for Amateur Radio operators: DXtreme Station Log 14TM.

New Features in DXtreme Station Log 14

DX Spot Checker Now Has Two Presentation Modes — Users can switch between Rich Site Feed and Grid Feed by clicking a tab on the window. The Rich Site Feed displays the actual, continuous feed from the Telnet server, and lets users interact with the server to set options like server-side filters and to perform queries. The new Grid Feed displays 10 to 50 rows (user’s choice) of DX spots in a structured, resizable, alternating-color grid. Grid-Feed spots can be displayed on a rotating basis (erase then continue) or by overwriting spots already displayed, as selected on the DX Spot Checker toolbar. Users can set fonts and colors for both feeds.
Suppress Verified Spots by Mode Per Band — When activated in DX Spot Checker Options, this client-side filter lets users suppress the display of spots for modes already verified within band plans defined on the Modes-Per-Band Plans tab.
JT Log Entry Processing — Users can have DXtreme Station Log 14 manage the pre- and post-log-entry population of the WSJT-X and JTDX log files, letting users perform all logging operations on the Station Log 14 window while keeping their eyes glued to the WSJT-X or JTDX interfaces for worked-before status indications. This feature is important when using quick modes like FT8.
Digital Application Assignment — When users add a JT log entry via JT Log Entry Processing, the Digital Application Used field is populated automatically with either WSJT-X or JTDX as appropriate. When using other applications, users can edit this field manually. And they can assign digital applications to pre-existing log entries by mode globally, filtered or unfiltered by date and band.
Club Log Record Creation — Users can create Club Log records in a special workfile automatically when adding or modifying log entries. The workfile can be viewed and edited, if needed, and uploaded via the Club Log web site. A Batch Upload to
Club Log function is available when Club Log does not contain all log entries.

Standard Features in DXtreme Station Log 14

DXtreme Station Log 14 lets hams log their contacts and import ADIF files from other programs. It supports major call sign subscription services, and offers the following multimedia and advanced functions:

DX Spot CheckerTM — Receives DX spots from Telnet-based servers and determines whether QSOs are needed for new or verified DXCC® entities, band-entities, mode- entities, or VUCC grids. Information displays on Rich Site Feed and Grid Feed tabs.
Automatic LoTW Upload — Users can set Station Log 14 so it uploads each log entry to LoTW automatically when added, capturing and saving QSO Record Status from the LoTW server as part of the process. Modified log entries can be uploaded as well. If desired, users can disable automatic uploading and can upload log entries to LoTW semiautomatically and manually in batches whenever they want to.
LoTW Reporting — Users can perform searches and run reports filtered by LoTW QSO Record Status, which indicates whether log entries are On, or Not On, the LoTW server following upload or QSL-updating. Users can also perform searches and run reports filtered by LoTW QSL Record Status, which indicates the date of each LoTW QSL record processed by DXtreme’s LoTW QSL Update Utility.
DX Atlas Integration — Performs Afreet DX Atlas azimuth plots from the user’s location to that of a spotted or logged station. Also creates maps for reports.
Rig Control — Tunes/retrieves frequencies and modes from supported rigs through integration with Afreet Omni-Rig.
QSL Processing — Creates QSL and address labels for physical QSLs, and supports the ARRL’s LoTW facility, including capturing LoTW QSL records as digital images.
QSL ImagingTM — Lets users scan and capture QSL cards and electronic QSLs into their log entries for browsing and viewing any time they want to.
Improv ImagingTM — Lets users associate adhoc images with their log entries separate from our popular QSL ImagingTM facility. Users can capture, scan, or paste any image and save it as a single-page .jpg, or single- or multi-page .tif. Improv images popular with users include signals on a spectrum analyzer or waterfall, QSOs conducted on ATV and data applications, and equipment used during contacts.
Audio Facility — Records and plays QSOs.
Reports — Provides a wide range of performance and station reports to let users see how well they’re doing. Reports can be filtered and sorted. Includes DXCC® and WAS AnalyticsTM tools for analyzing and enhancing DXCC and WAS standing.Operating System and Requirements, Pricing and Support

DXtreme Station Log 14 runs in 32- and 64-bit versions of Microsoft® Windows® 10, Windows 8.1, Windows 8, Windows 7, Windows Vista®, and Windows XP.
