Weird question . . . from the old retrocrank

The Grundig G3 sported a Dual Conversion PLL Digital tuner with smooth tuning and no discernible muting between frequency steps.

Like some others of my age (roughly) who have posted here, I vastly prefer radios that do NOT mute between tuning steps . . . that provide smooth, continuous tuning.

So, does anyone know of any true, new, currently in production, radios with an analog receiver? Could be AM, FM, and/or shortwave?

And, if there are any, obviously I am interested in the ones that you think work well.

Cheers, Jock

Checking out the XHDATA D-808

By Jock Elliott, KB2GOM

Size matters . . . especially when it comes to antennas. In general, the more aluminum or wire you can get up in the air (presuming, of course, that it is properly designed), the more signal you are going to pull in. A radio friend has a 560-foot loop erected on his property, and its performance is, well, impressive.

I’ve had my share of high-performance antennas over the years, and I enjoyed them.

Lately, however, I have yearned for simplicity. So when I encountered the phrase “Ultralight DXing” a couple of years ago, it had a kind of magic allure to it.

At first, I was intrigued: “What the heck is that?” I wondered. After poking around on the internet, I discovered that at the heart of ultralight DXing was the notion of having a whole lot of fun trying to hear distant radio stations (usually on the medium wave band) with tiny, shirt-pocket-sized radios.

Gary DeBock got the whole ultralight DXing thing rolling in 2007. He already had deep experience in DXing, having worked 144 countries as a ham radio operator with a 1-2 watt transmitter he had built. That was his apprenticeship in radio propagation. Then in 2007, he wondered if it would be possible, using his skill and knowledge of propagation, to hear Japanese and Korean broadcasters from his home in Washington State using – wait for it – a cheap pocket radio: a Sony Walkman SRS 59. At 1 am on an autumn night, he put propagation and operating skill to work and heard a couple of medium-wave stations from Japan and one from Korea.

In November 2007, he posted his results on the internet and got a lot pushback, the upshot of which was: “How could you possibly do this?

To which he replied (in essence), “Try it and see for yourself.

Some people did try for themselves, some with notable success. For example, one DXer from Canada logged 300 stations in 30 days. The idea caught fire, and ultralight DXing was born, concentrating on medium wave stations because there are lots of them to DX. (Ultralight DXers have their own forum, which can be found here: https://ultralightdx.groups.io/g/main )

In the intervening years, ultralight DXers have experimented with exotic antennas and achieved some astonishing results, but for me, the soul of ultralight DXing is simplicity: a tiny radio, a pair of headphones, and a comfortable place to sit.

In 2021, DeBock published an “Ultralight Radio Shootout,” and when I encountered it online, I saved it (I’m a bit of a pack rat with interesting files). Earlier this year, I was rummaging through my computer when I rediscovered the Shootout and found that DeBock thought very highly of the XHDATA D-808.

Now, here’s the weird part: strictly speaking, the XHDATA D-808 is not an ultralight radio. A radio must be no bigger than 20 cubic inches to be considered an “official” ultralight radio. The D-808 is actually around 27 cubic inches.

Curious, I contacted the XHDATA folks, asking if they would like to send me one for review, which they did, without charge.

The D-808 measures just under 6 inches wide, 3.5 inches high, and 1.25 inches deep and weighs about a half a pound. It receives:  FM: 87.5 – 108 (64-108) MHz, LW: 150 – 450 kHz, MW: 522 – 1620 kHz (9k Step) 520 – 1710 kHz (10k step), SW: 1711 – 29999 kHz (including single sideband), and AIR: 118 – 137 MHz. It is powered by an 18650 battery that can be recharged by a USB cable.

Others have written extensively about the D-808, but my overall verdict is that it is indeed, a neat little radio for listening in general. Because it has a larger internal ferrite rod “loopstick” antenna, it can do a better job of pulling in faint medium wave stations than some of the “official” ultralights with smaller internal antennas. In addition, the D-808 has a longer telescoping antenna that makes it easier to hear faint shortwave stations.

On the face of the D-808 are 24 buttons that control various functions, and they pretty much “work as advertised.” There is, however, one small issue that some users may find confusing. Just below the orange power button is a circular button marked SSB. Push it, and it engages single-sideband mode and can be used on medium wave as well as shortwave signals. Below that button, in tiny orange letters is an indication: USB/LSB. It refers to the INFO button below, NOT to the SSB button above. If you press the SSB button, hoping to switch between upper sideband and lower sideband, it will not work, and you will think the radio is broken (I spent several minutes searching the manual, trying find out what was wrong). When SSB is engaged, press the button marked INFO between to switch between sidebands, got it?

Playing around with the D-808 on a rainy Saturday morning, I found that it is a “hot” receiver – for its size – on medium wave, shortwave, and FM. Using the UP and DOWN buttons to search for stations, and I found that it would, indeed, find interesting stuff to hear that I could not hear so readily on “official” ultralight radios with smaller antennas. It’s a small, fun radio that virtually begs me to find a comfy chair, clap on the headphones, and tune around to see what’s out there.

Having said that, if this were a trip to Santa’s lap, there are a couple of things I would change about the D-808. The first is the soft muting that occurs between tuning steps, which is accompanied by a mechanical “clunk, clunk, clunk” at each step in both the main and fine tuning knobs. It’s like driving down a highway with expansion cracks or tar strips every 20 feet . . . it’s annoying. My personal preference is for smooth, continuous tuning, and, even when a radio has jumps between tuning steps, it is possible to deliver a smooth, “clunkless” tuning experience such as in the CCrane EP-PRO or the Tecsun PL-880. You can, however, get around the clunking by directly entering the frequency you want using the keypad (be sure to press the FREQ button first) or by using the UP and DOWN seek buttons to search for stations . . . the radio simply quiets itself until it find the next signal. Second, while the D-808 seems to just sip power from the 18650 battery, I prefer portable radios that are powered by AA batteries, since they are so readily available in so many places. In the grand scheme of things, that is a relatively minor consideration.

Bottom line: the D-808 packs a whole lot of fun and pleasing performance into a package that can be slipped into a jacket pocket. Even more important, it delivers the simplicity of an ultralight: a radio I can grab, kick back in an easy chair, slide on the headphones, and tune around for a bit of radio fun, and I can heartily recommend it.

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!

Raddy RE40 Emergency Radio

By Robert Gulley (Guest Post)

The Raddy RE40 is another portable shortwave radio offering from Radioddity, but with a twist – it is intended to be an emergency radio first, and a listening-for-pleasure radio second. In this review I will cover the emergency options incorporated into the unit, as well as discuss operability and its overall functionality as a radio.

As always when I do a radio review, I will point out what I believe are the radio’s strengths and weaknesses, as well as where this might fit in your radio arsenal. The usual disclaimer applies for any product I review – I tell it like it is, good or bad. While the radio was provided to me without cost by Radioddity, that does not affect my opinions one iota. With that out of the way, let’s get into the meat and potatoes of the rig!

As we have come to expect from other Raddy portables, this has a lot of features packed into a relatively small package. I say “relatively small” because it is thicker than many vertical portables, and heavier. This is a solid bit of kit, and the size and weight are the first clue that this radio is not just intended to sit on a coffee table. It is definitely designed to work outdoors, as well as finding a place in the car or boat for when you need to check on the weather, or be out in it.

Specifications

    • Frequency Range: FM: 87-108MHz, AM: 520-1710KHz, SW: 5.7-17.9MHz, WB: 162.400-162.550MHz

    • Card Type: MP3/WAV/FLAC/APE
    • White Noise: 7 different natural sounds
    • Max. Capacity of Micro SD Card: 256GB (not included)
    • Size: 81x52x132mm / 3.2x2x5.2in
    • Weight: Approximately 350g / 0.77lb
    • Operating Voltage: 2.7V-4.2V
    • LED Light: 1W/120LM
    • Max. Power: About 5W
    • Speaker: 4? 5W
    • LED Flashlight: 1W/120LM
    • Battery Capacity: 4000mAh / 3.7V (non-replaceable)
    • Operating Temperature Range: -10? to 60??14°F to 140°F?

What’s in the box?

    • 1 x RE40 Radio
    • 1 x Type-C Cable
    • 1 x Wrist1 x User Manual

Power Options

This radio can be powered by an internal battery charged by a USB-C port, solar powered to charge the battery, or by a hand crank. Here is the manual description of the emergency power options:

A. Solar Charging

  1. Put the solar panel directly towards sunlight. When the green charging indicator lights on, it indicates that the solar panels charging the internal battery.
  2. The charging efficiency depends on the solar exposure: the stronger the sunlight, the better the charging effect.

B. Hand Crank Charging

  1. Turn the hand crank clockwise or anti-clockwise and the green charging indicator will light up to indicate that it is
  2. Speaker has no sound: Hand crank at 130-150 rpm for 1 minute, the flashlight can be used for more than 30+ minutes or play the radio (medium volume) for 3

NOTES:

  1. The hand crank can be turned for 3-5 minutes before using the product to activate the internal battery.
  2. The hand crank is normally used in emergency situations when the power is out.

Solar Panel

The radio has a compass built into the volume control knob on top, a flashlight, analog tuning dial, and switches for moving between playback modes (Radio, Bluetooth, and media) and desired operations (SOS, Standard battery or solar/crank charging modes, and USB charging). As an aside, the SOS feature is LOUD!

Almost the whole back of the radio is devoted to the solar cell. This is much larger than other solar cells on portable radios that I own, and presumably will recharge the internal battery faster. There is a rubber flap over the headphone, USB and memory card jacks/slots.

The unit has another interesting feature: you can charge your phone or other USB device from the standard USB slot under the flap. To use this feature the mode switch on the back of the radio has to be in the right-hand position under the charging symbol. When set to charge another device all other functions are disabled, so if you turn your radio on and can’t get anything to work, you might just have pushed the button over to the right accidentally, or intentionally the last time you used the radio.

Radio Performance

I’ll not spend a lot of time here, not because the radio performance is poor, but because as I have already noted, that is not the primary focus of this radio. There are plenty of portable radios by Radioddity and others which have better performance. However, I found the FM reception to be exceptional for a radio in this class, and AM radio reception to be reasonably acceptable for a radio with a lot going on inside. I did not test the AM radio reception with one of my loop enhancement units, mainly because I am not looking to use this as a regular radio receiver. This is going in my car for emergency/safety issues, and to grab when I am having a picnic lunch or the like.

Shortwave reception is on par with other radios of this size, and a pleasant feature is a sturdy telescoping antenna. Unlike several other small Raddy radios which have very fragile antennas, this one is much more solid.

Weather band reception is decent, but not quite as good as other radios I have tested. I can pick up one very strong signal, and a usable/readable second signal, but some other radios I have give me 4 or 5 stations. Of course, as long as you can get one strong signal, it is likely that is the one most important to you in your immediate location. With at least a second station you have the chance to pick up information should the one nearest you experience difficulties.

Sound and White Noise

As for the sound quality, it has a nice large speaker and delivers good sound, and I have found this typical of most all of the Raddy radios I have tested. In addition to the typical sleep timer radio option, this radio features a “white noise” option which allows the user to select between 7 different white noise options for those who prefer to go to sleep that way.

Compass and Flashlight

Pros

  1. Feature-Packed in a small footprint
  2. Loud SOS
  3. Sturdy Antenna
  4. Large Solar Charging Cell
  5. Ability to charge phone
  6. Multiple ways to power radio/flashlight
  7. Strong FM, acceptable AM and Shortwave (no SSB)
  8. Price ($49.99 from Radioddity, $44.99 plus 10% off coupon from Amazon at time of writing. There is also a bundle offer from Amazon which includes an SP4 4W Portable Solar Panel for $59 plus 10% off coupon) [Note that these are affiliate links that support the SWLing Post at no cost to you.]
  9. 18-month(!) warranty

Cons

  1. Weather band not as impressive as some other radios, but hardly a deal-breaker
  2. Analog tuning dial very sensitive (if you have shaky hands this is probably not for you, except perhaps for the emergency functions)
  3. Multi-colored striped analog dial is sometimes hard to read (then again, I need my reading glasses for a lot of things!)

Wrap-up

This little radio packs a lot of punch for the money, adding features similar emergency radios do not have. If you are like me, emergency radios are a necessity given our unstable weather and power grids, and I like knowing I can use solar power to recharge a radio, or crank it when the sun is not available. Some folks expect more power from a hand-crank generator than these small radios produce, but my main goal is to be able to quickly check weather conditions, use the flashlight, or make use of the SOS function if needed. These do not require massive amount of time spent cranking the generator, and to me that is a plus.

I would recommend one for each car or boat, or to take with you on outdoor trips just in case of an emergency. Of course, you could always listen to the ballgame on your front porch, too!
