XHDATA-608WB

XHDATA Weather Radio D-608WB

Review By Robert Gulley, K4PKM

This is my first experience with an XHDATA radio, and my initial impressions are quite positive. This weather radio has an impressive set of features and appears to be built quite solidly. I say “appears” because I have not done (nor intend to intentionally do) a drop test! But my sense of the radio is that it can withstand some knocking about while still functioning (but please do not test this theory! YMMV!).

Solar Cells

Solar cells with a twist – the cells along with the LEDs can be rotated up and down

 

LED lights

Three brightness levels for these LED lights – a nice touch!

 

 

 

 

 

Let me start with the items that impressed me.

  1. Weight. This is not a typical light-weight radio. It feels solid, has some bulk to it, and I like the feel. It weighs in at 11.5 ounces, which is comparable to the two other solar powered weather radios I own, which come in at 12 and 12.25 ounces respectively.
  2. This radio has both a torch and an LED panel, each with 3 levels of brightness. While you will not light up a room with either, they are both quite sufficient for their intended purposes. The LED is particularly useful to light up the immediate area around the radio, and on it’s brightest level puts out a good amount of light. Being LEDs, the power drain is very reasonable.
  3. The radio is powered by multiple sources of course, as is typical with today’s weather radios, but a unique feature compared to my other radios is an articulating solar cell (and LED) panel. This allows you to follow the sun for quite a while as it rotates in the sky.
  4. The antenna, while not very long, is very solid and should last a long time if not subject to abuse (and looks to be easily replaceable if something does happen).
  5. The battery is easily accessible and replaceable with the now-common 18650 rechargeable battery. (As an aside, for those who, like me, prefer to charge batteries outside a radio when possible, there are charging units available from the usual sources if you want to minimize heat and charging wear-and-tear on your radios and flashlights.)
  6. The ATS function works quite fast on FM, finding 21 stations in my very rural area just off the built-in whip antenna
  7. Keypad layout is minimal and functional. For those wanting a direct-entry frequency keypad, this radio is not so equipped. However, running through the memory channels is easily done, without multiple menu hoops through which to jump.
  8. Tuning is both a blessing and a curse (see cons below for the negatives) – the tuning can be accomplished at two different speeds, allowing for a slow tune and a bigger jump depending on how fast you turn the tuning dial. This can be particularly useful with SW, but also when manually scanning the MW band or when finding tracks on a memory card.
  9. The crank can be extended as a stand at a few different angles. I am not sure if this was intended, but it works nicely!
  10. When in SW mode, the band is displayed as you tune (i.e. 41mb, 25 mb, etc.)
Crank can act as a stand

I am not sure if this was intended or not, but the crank can act as a stand

Less impressive (but see conclusions):

  1. Tuning can be slightly erratic, making bigger jumps at times than intended. This can happen in slow mode (one click of the tuning wheel at a time), or it can happen when the tuner switches between slow and fast mode and you didn’t think you were turning it fast enough for the switch. On the plus side, there is one arrow displayed when tuning in slow mode, and two arrows when in fast mode, so it is easy to see when it has switched modes.
  2. There are rubber strips glued into slots on the bottom of the radio to give it a little more resistance to sliding, but I feel it makes the radio slight more unstable – you may disagree since the effect is minimal.
  3. Soft muting when tuning – I know this is a biggie for many folks, so I mention it (again, see conclusions)
  4. No SSB (not that I expected it).
  5. Three NOAA stations come in for me which is typical, but I do have weather radios which can receive 4 well enough to copy, so not quite as sensitive. However, two or more is adequate to catch weather forecasts for your area in case your closest station is down for some reason
  6. ATS on SW and MW was not impressive – perhaps moving too quickly? Many stations come in with good audio, but the scan did not find them. Again, YMMV.
USB and Power Connections

On the side are the input and output USB connections, along with the TF card slot.

Conclusions

I find this to be a good radio for its intended purpose – a Weather Alert radio with solar, lights, and multiple charging power options for operating, and an option for charging small devices if needed. This is not, nor should it be compared to, stand-alone shortwave radios. This is a bonus, and it works well for AM shortwave stations. That it does not have SSB is not an issue for me – I have plenty of radio options to enjoy during a power outage which are capable of SSB upper and lower sidebands.

The soft muting will no doubt bother some, but again, this is is primarily a weather and emergency radio, not a radio designed for pleasurable shortwave listening. As for the audio itself, the speaker produces a good clean sound, and there is even a type of bass boost which helps the audio even more. AM, FM, and SW stations sound good, and I find the audio to be quite strong out of this compact unit.

A replaceable/removable battery is a real plus for me both in terms of charging and for popping in a fresh battery while charging a drained battery. I like having backups for my backups, so this is right down my alley.

The unit is a good size, compact but solid, and has all the useful controls easily reached/manipulated. The antenna is solid, the LED lights are a nice touch, and it is a radio I believe could be counted on when needed. (Oh, and it is reasonably priced as well!)

As always, these are my personal, honest opinions. While the XHDATA folks approached me for the review and sent a unit to me free of charge, I always call it as I see it, good or bad.  I happen to think this radio is a keeper!

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Annual Armed Forces Day Crossband Test Postponed (ARRL News)

Due to the ongoing COVID-19 response and mitigation actions, the 2020 Armed Forces Day (AFD) Crossband Test scheduled for Saturday, May 9, has been postponed. Because it’s uncertain just when stay-at-home orders will be lifted across the US, AFD planners chose to postpone this year’s event, because the government stations that typically support this event may not be available. Armed Forces Day Crossband Test planners are considering scheduling a November event in honor of Veteran’s Day, depending on COVID-19 mitigation actions. During the AFD Crossband Test, military stations in various locations transmit on selected military frequencies and announce the specific ham frequencies they are monitoring to work radio amateurs. — Thanks to US Army MARS Program Chief Paul English, WD8DBY

Radio Australia Event – Antenna Overview (Mount Evelyn DX Report)

Thanks to Lee VK3GK for this short video of the antennas used for the recent Radio Australia event using the call sign VI3RA. Take what will possibly be a final look at the feeders, switching boxes and antennas before they are pulled down and junked!

Also here is the final transmission of the event weekend with, of course, the famous Radio Australia music box interval signal.

World War II and Radio (All Things Radio)

I have added an article I wrote some years back on the code breaking efforts of the Allies during WWII. While certainly not exhaustive, I found many of the connections between countries and equipment rather fascinating, and new things continue to pop up regarding Bletchley Park’s role in training officers and decoding texts. While most famously known for breaking the Enigma code, also significant was the breaking of the Lorenz Cipher.

Radio Waves: New FCC RF Exposure Limits, Rediscovering Spark Gap, Zoom Vulnerabilities, and Extremely Rare Film of MI6 Section VIII

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Paul Evans, and Robert Gulley for the following tips:


FCC Publishes new RF exposure rules (Federal Register)

The FCC has published the new rules in the Federal Register.

Paul notes:

Different above 6GHz
Expanding rules from 3 kHz – 300 GHz to 3 kHz – 3 THz (inc. light
frequency RF sources, essentially future proofing rules)
Introducing SAR measurements from 100 kHz to 6 GHz (impact to ARS)
Introducing MPE measurements above 6 GHz
Introducing ideas for WPT at and below 100 kHz, with control over the
wires or remotely over the air. This is (obviously) for EV charging.
They say nothing about harmonics, filtering, etc.[]

We Rediscover Spark Gap Radio by Accident (CuriousMarc via YouTube)

It’s 1890 all over again in the lab. By complete accident, I find myself the new owner of a high voltage box that turns out to be a vintage Xenon lamp sparker. Not only do we make it work, but we use it to retrace the critical experiments that led to the discovery of radio, using the lamp starter as the spark gap transmitter, and a coherer as the receiver.[..]

Zoom taking your club online – DON’T (Southgate ARC)

On Friday 3rd April, we carried an item regarding the use of Zoom for club meetings.

However, we have since been contacted by Paul, VP9KF, who offers this note of caution.

He says:
“This story http://www.southgatearc.org/news/2020/april/zoom-taking-your-radio-club-online.htm on your page recently is over-shadowed by the news as follows:

https://www.theguardian.com/technology/2020/apr/02/zoom-technology-security-coronavirus-video-conferencing

Don’t use Zoom and get hacked ”

Our thanks to Paul for this informative, if not rather worrying, news item.

WW2 Codebreakers: Bletchley Park activities revealed in unique footage – The Hidden Film (YouTube)

Discover the story behind the recently discovered only known wartime film footage of a secret site connected to Bletchley Park.

A silent film, recently donated to Bletchley Park Trust, is believed to be a compilation of footage recorded between 1939 – 1945, showing members of MI6 Section VIII at Whaddon Hall, Buckinghamshire. During World War Two, this was a most secret site where Ultra intelligence produced by the Government Code and Cypher School (GC&CS) at Bletchley Park would be sent, and then passed on to Allied commanders in the field.

In this mini-documentary, hear Bletchley Park Veteran, Geoffery Pidgeon who worked in MI6 Section VIII during WW2, recall how it felt to watch the film for the first time and recognise his father. Peronel Craddock, Bletchley Park’s Head of Collections and Exhibitions and Dr. David Kenyon, Research Historian at Bletchley Park also talk about why the discovery of this film is so important.

Robert’s Series: “The Care and Feeding of Electronic Equipment”

SWLing Post contributor, Robert Gulley (K4PKM–formerly AK3Q) recently posted two excellent articles on his website about the “care and feeding” of electronic equipment.  Here’s the description from Robert’s blog, All Things Radio:

Just a quick note to let you know there are two new articles published in the Reviews and How-Tos section dealing with simple checks and preventative care of electronic equipment. Over the years I have learned some important lessons for keeping computers and radios working properly, with the goal of having as little downtime as possible. The two articles were originally published in The Spectrum Monitor June and August issues, respectively. (If you have not subscribed to this magazine, you really should check it out – it is in my opinion the best radio magazine on the market today, and not just because they occasionally publish my articles!)

Here’s a quick link to the review page:

eBay find: Zenith Transoceanic in an Unopened Box

zenith-transoceanic

Many thanks to SWLing Post contributor, Robert Gulley, who shares this link to an eBay auction for a Zenith Transoceanic D7000Y in an unopened box!

Let’s be clear here: this is no “Black Friday” deal. The seller has this gem listed at $5,800 plus shipping! I think this is the first time I’ve ever seen a Transoceanic listed at this price level.

zenith-transoceanic-ebay

Of course, as one friend always reminds me: “eBay is there to show you things you’d rarely stumble upon in daily life–you just need a chunk of change to snag it!”

The seller is listing this as-is since he isn’t going to open the box to test the unit. He does claim that if it arrives DOA, he’ll have is repaired free of charge (buyer pays shipping).

Still: $5,800 is hefty sum–several thousand over my threshold! No doubt, a Transoceanic collector will snag this eventually.
