Live Baseball on the Radio: Radio Selection Considerations

The authors own Sangean Portable + AirPod Pros + a Bluetooth Transmitter rubber banded to the radio back, Coca Cola Park – Allentown, PA

In recent years, I’ve enjoyed attending minor league baseball games in my region. One of my favorite aspects of live baseball is bringing a radio to listen to play-by-play commentary. Experiencing the game in person while hearing the commentary in my ear offers the best of both worlds.

Over the years, I’ve brought various portable and ultra-portable radios to games, and I’ve realized that certain criteria make for a good “Live Baseball Radio.” Whether it’s form factor, size, or features, a live sporting event presents specific considerations and trade-offs for the radio you choose to bring.

“I’ll just stream the game on my phone”

While there are many options for internet streaming on a smartphone, like the free game audio feeds from MiLB.com, streaming game audio on a smartphone is not ideal for live baseball due to one major issue: latency.

Ideally, you want the action you see to match as closely as possible with the play-by-play you hear. With internet streaming, you’re subject to internet latency and buffering, leading to audio delays that you cannot fix. This makes streaming better for listening to games from afar, but not for live baseball.

Selecting the Ideal Radio

Picking a radio to bring to a game involves considerations that become obvious only after you’ve tried it a few times. Hopefully you can learn from my past mistakes and be more informed.

AM, FM, or AM/FM?

There are no fixed rules about the frequency’s baseball teams use for broadcasting. Some teams are on AM radio, some on FM, and some simulcast on both. Some teams don’t broadcast on free-to-air radio at all, opting for streaming-only solutions. Choosing a radio that receives both AM and FM is your best bet to ensure you can use it at different stadiums.

Many ultra-portable “pocket” radios support only FM, which might leave you without audio if your local team is on AM. Conversely, vintage pocket transistor radios might leave you stuck with AM-only signal receiving capability, missing the FM signal.

HD Radio

The Author’s recent ill-fated radio choice for a live game

While HD Radio seems like a great idea for live baseball, the HD signal suffers from similar issues as streaming a game: latency

I recently picked up an ultra-portable FM HD Radio for a great deal secondhand, only to take it to the ballpark and realize the HD Signal was delayed by nearly 20 seconds. Worse yet – the radio offered no way to turn off the HD signal and revert to analog! The radio was unusable for watching the game as play-by-play in my ear was nearly four pitches behind what I was seeing live.

If you choose a radio with HD Radio features for the ballpark, check the broadcast delay on the HD signal before the game, and ensure you can turn off the HD Radio features if necessary.

Radio Size and Antenna Considerations

Any radio can be portable if you try hard enough, but space is often limited at live sporting events. Stadium seating varies at some ballparks, you can spread out a blanket on a hillside, sit at a picnic table, or even watch the game from a pool (better check that IPX rating!). However, you’ll likely be using your radio while seated in your ticketed seat. Some stadiums offer spacious, modern seating, while older stadiums may have small, cramped seating.

Antennas on radios are another consideration. In cramped stadium seating, you may not have the luxury to fully extend the antenna for the best signal without poking the person in front of you or next to you. You might want to consider a radio without an external antenna, such as one like the Retekess V112, which uses the headphone cable as the antenna. You may also need to stand up and sit down repeatedly to let people through the aisle rows to their own seats, which is where going “antenna-less” can be useful.

While a headphone-wire antenna setup may be a perceived undesirable feature for dedicated radio hobbyists, pocketability and ease of use in a crowd can be beneficial at a crowded game. Many stadiums are moving towards bag restrictions or not allowing bags at all, making the proposition of transporting even a modest-sized portable radio to a game a chore. A pocket-sized radio you can stick on a lanyard, wear into the park, or stick in a pocket may be the difference between being annoyed all game carrying around a radio, or just enjoying it.

On the flip side, if you plan on pairing your radio with a Bluetooth transmitter to use Bluetooth earbuds or headphones, you may want to select a radio with an antenna. The short cable run on many Bluetooth transmitters may not provide adequate reception for units that use connected headphones as the antenna.

Speaker or No Speaker

If you’re not using the radio for tailgating, consider whether you need a speaker on the radio. Many pocket radios omit a speaker to reduce weight and cost. If you need to unplug your headphones during the game, it might be better to avoid a speaker that could blast game audio accidentally and disrupt your neighbors. Ditching the speaker is also likely to save weight and battery life.

Cost Considerations and Final Thoughts

Choosing the right radio for live baseball involves considering factors like frequency options, latency issues, size, portability, and whether you need a speaker.

Everyone’s finances and purchasing abilities differ, but there are many adequate radio options available for under $20 USD that check a lot of these boxes, making it possible to have a dedicated radio for live sports without spending a lot of money. As radio hobbyists, we sometimes want the best for our listening experiences, but taking an expensive radio to a live sporting event can be risky due to cramped quarters, constant movement, and the potential for spills or accidents.

In my opinion, it’s better to enjoy the game with a “lesser radio” than to spend the entire game worry about damaging an expensive radio. After all, cleaning mustard out of your expensive radio’s speaker grill is not fun post-game entertainment. Focus on enjoying the day and the live sporting experience while enhancing it with the wonder of live ballpark radio – no matter what you bring along.

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 Aaron Kuhn, Ron Chester, Ronnie Smith, Dan Van Hoy, and Dennis Dura for the following tips:

The Airwaves of Navajo Nation (The Verge)

KTNN radio station’s headquarters in St. Michaels, Arizona is less than ten minutes away from the Navajo Nation capital of Window Rock, but its reach encompasses all 27,000 square miles of the Nation across four different states. The station has been broadcasting bilingual content in both the Navajo language, Diné Bizaad, and English for over 35 years. But the station is quiet nowadays — many staff members are working from home if they can. That includes Dee Dixon who, after 15 years at KTNN, had to install internet access to her home an hour and a half away in Dilkon, Arizona so she could broadcast her 6AM show.

Her regular listeners are scattered. During the day, KTNN covers the majority of the Navajo Nation across New Mexico, Arizona, Colorado, and Utah. One can also tune into KTNN’s programming online via livestream from anywhere in the world. It is not the region’s only media. A few regional newspapers cover the reservation extensively, and Navajo Nation is also the only tribe in the country that owns, funds, and operates its own television station. But none of these mediums produce stories primarily in Diné Bizaad: radio is the only way to hear the language in local media.

When the COVID-19 pandemic bore down on Navajo Nation in early 2020, Dixon noticed a distinct divide between her regular listeners at home on the reservation and those outside of it. As Dixon worked on translating public health announcements and taking calls on the air, she noticed an uptick in listeners tuning in from Florida, Maine, Alaska, Louisiana, and Montana. Those callers away from home were hungry for local updates to know what was going on within the Nation — an ambiguous virus that no one understood thoroughly just yet was spreading. People wanted to know if their families were safe and just how transmission was occurring in a place where households are far flung across vast swaths of desert. But Dixon realized as her local listeners, specifically elders, called in that they wanted something different from her: they did not want to hear about the virus whatsoever, no matter how high the rates of infection in Navajo Nation were.

“According to Navajo tradition, you’re not supposed to give a name to anything that is not good for the reservation,” Dixon says. “The virus was like a monster. Traditionally, the more you talk about something like that, the more you’re inviting it into your home.”

Navajo Nation is the second-largest Indigenous tribe in the country with about 300,000 enrolled members, over half of whom live on the reservation. Much of the land is rugged and rural. Of those on the reservation, about 27 percent of households do not have electricity. Cellphone service can be spotty to nonexistent.

But transistor and car radios do not require electricity to function. Radio waves are not dependent on cell towers. In fact, KTNN was the last station in the country licensed for a clear-channel radio signal at 50,000 watts — a strength used in the early 1900s to provide rural America with radio that wouldn’t be vulnerable to interference.[…]

Japan’s only shortwave station still in business after 80 years (The Asahi Shimbun)

KOGA, Ibaraki Prefecture–Standing tall and proud over an area of 1 million square meters or so, a forest of steel towers in two-tone red and white is the dominant feature under the blue sky against the backdrop of Mount Tsukubasan.

This is KDDI Corp.’s Yamata Transmitting Station, the nation’s only facility broadcasting shortwave radio programs to overseas listeners.

The station started broadcasts on Jan. 1, 1941. The main building still retains a prewar ambience.

Shortwave radios were the primary means for people across the world to receive audio content from Japan without a large-scale facility before satellites and submarine cables came into existence.

The 1945 announcement of Japan’s surrender by Emperor Hirohito was transmitted from here to military personnel on overseas battlefronts.

When it was completed in 1940, Yamata, now part of Koga, was a typical farming village with a population of 4,536, of whom 90 percent were farmers, according to a 1941 local history pamphlet.

“A large area of flatland was available, and it was less prone to damage from snow and typhoons,” said Kazuhiro Matsui, 50, a senior official in charge of infrastructure, who served as a guide when the station was shown to media representatives in April. “I think it was the only place fit for the station in the country.”

The steel towers are arranged in such a way that 18 transmission antennas cover 360 degrees to send broadcasts as far north as Boston and London and as far west as Seoul and Nairobi.[…]

Why Does the World Harbor So Many Different Voltages, Plugs, and Sockets? (IEEE Spectrum)

Blame it on the varied evolutionary history of electric power grids and the products that have grown up alongside them

Standardization makes life easier, but it is often impossible to introduce it to systems that have a messy evolutionary history. Electricity supply is a case in point.

Edison’s pioneering 1882 Pearl Street station transmitted direct current at 110 volts, and the same voltage was used when alternating current at 60 hertz took over in American homes. Later the standard was raised a bit to 120 V , and in order to accommodate heavy-duty appliances and electric heating, North American homes can also access 240 V. In contrast, in 1899 Berliner Elektrizitäts-Werke was the first European utility to switch to 220 V and this led eventually to the continent-wide norm of 230 V.

Japan has the lowest voltage (100 V) and the dubious distinction of operating on two frequencies. This, too, is a legacy from the earliest days of electrification, when Tokyo’s utility bought German 50-Hz generators and Osaka, 500 kilometers to the east, imported American 60-Hz machines. Eastern Honshu and Hokkaido island operate at 50 Hz. The rest of the country, to the west, is at 60 Hz, and the capacity of four frequency-converter stations allows only a limited exchange between the two systems.

Elsewhere, the world is divided between the minority of countries with voltages centered on 120 V (110–130 V and 60 Hz) and the majority using 230 V (220–240 V and 50 Hz). North and Central America and most countries of South America combine single voltages between 110 and 130 V and the frequency of 60 Hz; exceptions include Argentina and Chile (220/50), Peru (220/60), and Bolivia (230/50). Africa, Asia (aside from Japan), Australia, and Europe work with the higher voltages: 220 V in Russia and Ethiopia; 230V in South Africa; and 240 V in Brunei, Kenya, and Kuwait.[…]

Midland WR120 Review: Aaron says weather radios, like smoke detectors, are something we all need

7 Replies

Many thanks to SWLing Post contributor, Aaron Kuhn, who writes:

“Weather radio? I’ll just use my cellphone for alerts.”

If you’ve ever uttered or thought the above words – take heed.

Late last week I awoke at around 12:30 AM to the sound of some incredibly strong winds outdoors. Glancing down at my completely muted phone, I opened up my text messages to reveal a Tornado Warning. In a panic, I threw on some clothes, gathered a dog harness and leash and made my way the pantry closest for shelter.

Then I checked my phone again – and realized that tornado warning was from 30 minutes ago and already expired. Crap. That was too close for comfort. I promptly went on to Amazon and ordered the Midland WR120.

I unboxed and set the radio up yesterday and I’m quite happy with it.

The first thing I suggest doing after initial setup is turning off the button beeps which are incredibly annoying. Past that, I’ve found the radio perfect for my needs of setting it on a window sill and (hopefully) forgetting about it until it alerts me to any nearby danger.

Since SAME Alerts work on a county basis, I was very happy to discover this radio allows you to disable certain kinds of alerts that may not be relevant to you.

One thing that I think Midland should include in the box printed (instead of ads for weather apps they don’t publish anymore!) is the “Editable Events list:
http://midlandusa.com/wp-content/uploads/2011/11/Editable-Events.pdf

By default, the radio doesn’t allow you to turn off 30 some events, including Tornado Warnings among them – this is a good thing in my opinion! However, it is a bit concerning when you first go to setup the radio and realized Tornado Warning is missing in the alert list. The reason for this is because this is one of the 30 some alerts you can’t disable.

Overall I’m happy with the radio, and hoping it’ll never fire off in the middle of the night on me any time soon – but I know it’ll be a lot more reliable than my cellphone prone to being muted.

I view weather radios like smoke alarms now, it’s stupid for you to not have one. I wasn’t expecting Tornadoes in November in Southeastern Pennsylvania, but apparently nature is one to surprise us continuously.

Thank you so much for sharing your story and your WR120 review, Aaron.

I love this quote: “I view weather radios like smoke alarms now, it’s stupid for you to not have one.” I agree completely!

A few weeks ago, there was an alert sent to every phone in the US all at the same time. I received my alert nearly 30 minutes late. Mobile phones and their networks are pretty amazing technology, but they’re not flawless.

We are so lucky to have a robust weather radio broadcasting infrastructure here in the US and Canada. An inexpensive radio like the WR120 will deliver weather alerts reliably and give you a preparedness edge.

And thank you for mentioning the number of events you can edit out of the alert system. No sense in receiving alerts you don’t need.

In addition, some weather alert radios default to receive alerts from counties and regions surrounding your own. I would suggest turning those off–limiting the alert area to your own county–else you could get a lot of alerts that don’t pertain to your location. Using the smoke detector analogy, receiving alerts from surrounding counties is much like putting a smoke detector directly over your stove! You’re just asking for false alarms. 🙂

Thanks again, Aaron, for the important PSA!

Keep in mind as the holiday season approaches: weather radios make for life-saving, affordable gifts.

Guest Post: A review of the XHDATA D-328 portable radio

Many thanks to SWLing Post contributor, Aaron Kuhn, who shares the following guest post:

XHDATA D-328 Radio Review

by Aaron Kuhn

Disclosure: This radio was supplied at a 99% discount by the manufacturer, costing me only $0.15.

About Me

I live in the Philadelphia Suburbs, where there’s ample FM Stations, good AM Coverage, and also a lot of noise when it comes to Shortwave. I’m mostly an AM/FM listener, who occasionally likes to dabble in Shortwave. My idea of a good radio is something I can turn on, put up the antenna, and it just works.

Initial Impressions

The Radio is boxed simply enough in a cardboard box, with a small amount of bubble wrap inside, manual, Mini-USB Cable. The Lithium-Ion Battery comes pre-installed.

Operation of the radio is mostly straight-forward, and I doubt you’ll need the manual for anything. The manual itself contains your normal badly-translated English phrases and doesn’t make sense in a lot of places (did you know this radio uses high quality PU edge big size?)

Two curious notes about the manual:

It mentions you should remove the “18650 Lithium Ion Battery”, but this radio doesn’t use an 18650 battery. Instead, this radio uses a “BL-5C” Battery, which based on my research looks like it was pretty common on Nokia phones around 2004.
Someone took white-out to the manual where it says “Set the function switch to the “MP3” position and insert the USB Stick or TF Card, with “USB stick” covered in white out.

The radio itself is made of a slippery, glossy plastic that doesn’t inspire confidence, but also seems to have enough structural stability it doesn’t worry me. I’d guess this radio could take a moderate drop and bounce and be OK, but it’d probably crack if dropped from above waist level.

I ran into a somewhat funny problem trying to insert the included wrist strap into the hole in the back of the radio. Unlike most radios with a wrist strap hole that’s closed off, the wrist strap instead continued down into the radio. That is, the wrist strap “loop” molded in the plastic is actually a hole into the radio. This doesn’t bode well for dirt or other junk getting pushed into the radio accidentally. I was able to eventually get the wrist strap on the loop, but it was far harder than it should have been.

Design

The Lithium Ion battery comes pre-installed in the radio, and the battery door it’s behind seems sturdy enough. Fortunately, there’s really no reason you should ever have to pull the battery out of this radio unless you need to replace it. Running the Battery model # across Google and other sites shows this should be a very cheap battery for you to replace at between $1 and $3.

Battery Door

Kickstand deployed with battery door open

Li-Ion “BL-5C” Battery

I very quickly noticed a big glaring design flaw on this radio with the poorly designed, super small kickstand located next to the battery compartment. This small, off to the left kickstand works fine if the radio is on a perfectly level surface like a nightstand, but causes the radio to tilt over if you try to place it on a soft surface like a bed or a pillow. I would have liked to see just one large combination battery door/kickstand if possible across the back of the entire radio.

Design problem number two with the radio became very apparent when trying to extend the telescoping antenna. The antenna butts up against the plastic molding on the back of the radio, meaning you cannot prop the antenna up “Straight” when using the kickstand. This results in the antenna having to angle off at around 45 degrees, which is a bit annoying. My Tecsun PL-310ET doesn’t have this problem due to having a cut-out notch to allow the antenna to be in a more upright position.

“Upright” Antenna trouble

Tecsun PL-310ET for Comparison

The tuning knob has a satisfying amount of resistance to it, and doesn’t spin too quickly or too slow. The volume knob, while smaller, spins freely and also feels solid.

The band selector selects between FM1-2, AM, and SW 1 through 9. The switch to move between these bands has a satisfying amount of click and feedback to it, and isn’t mushy and you likely won’t pick the wrong band. The small window displayed below each band number fills with a small, mechanical, plastic bar attached to the switch. The window and bar were slightly misaligned, making it difficult to tell at a glance which band I had selected.

The tuning bar itself moves smoothly across the band, but the metal extension piece running down the shortwave part of the spectrum tuning was not vertically straight and had a noticeable bend to the lower right.

Weight – this radio is INCREDIBLY light! The choice of a Li-Ion rechargeable battery pays off here, and when I weighed the radio it came in at exactly 160 Grams / 5.7 Ounces. The compact size of this radio and the weight would cause it to easily disappear into a coat pocket and I’d forget I was carrying it. This definitely qualifies as super-portable in my book.

The choice to use Mini-USB instead of Micro-USB on the charging is a questionable one. Micro-USB is the much more common connector you’ll recognize if you’ve bought a Smartphone in the last 3 years, or any other consumer device with a USB connector. Based on my short research, Micro-USB despite being smaller than Mini-USB, offers a number of benefits including increased cycle-count on the number of plugs/unplugs before the connector wears out. I don’t know why XHDATA went with Mini-USB on this, and I’d suggest they move to Micro-USB for future revisions. The Mini-USB, other than being slightly easier to plug in, seems to offer no benefit and is obsolete compared to Micro-USB.

Audio Quality

Wow! While I may have had some hesitations about the radio’s design, I was incredibly surprised by both the loudness and fidelity of the speaker on this radio. The volume was incredibly loud, and the audio did not distort even when I turned this to the highest setting. While a mono speaker, voices on AM were quite clear and nice to listen to, and music on FM Sounded way better than it deserved to sound coming out of a $14 radio.

Plugging in a pair of earbuds (not included) also produced crisp, loud audio, with no noticeable whine or hiss. Volume levels should be more than adequate. Audio came in through both Left and Right earbuds, but I was unable to tell if the output was actually Stereo when listening on FM. The word “stereo” is not mentioned anywhere in documentation, so I would not be surprised to learn this radio is mono-only.

Tuning

I don’t normally use analog radios, so tuning the D-328 was a bit of a challenge. The cramped display provided little feedback, and the crooked tuning bar didn’t help either. FM Stations seemed to be needed to be tuned “high” About 1MHz from where I thought they should be, and AM Stations about 50 KH above where I thought they should land. Tuning Shortwave seemed like a total crapshoot, being fairly imprecise.

I’m mostly an FM/AM Radio listener, and all the usual local suspects popped right in and tuned easily for me. Static between stations is kept very low, and when a station locks in on FM it pops in very clearly. Selectivity between close adjacent stations can be challenging due to the small tuning dial and skewed visual feedback, but I was able to tune in every FM Station I tried.

I am located in the Philadelphia Suburbs, so my usual station for tuning in a weak signal is WPRB 103.9 out of Princeton. I’m happy to report it came in just as clear as it did on my Tecsun PL-310ET, with no trouble finding it.

AM was more of a mixed bag with tuning. Stations I did not expect to come in clearly seemed to pop in with strong signal strength, while the “go-to” AM Test station of KYW 1060 proved surprisingly difficult to locate on the dial. Audio levels on AM were noticeably wider in variance of signal, with some stations proving almost too quiet to listen to.

I’m honestly not much of a Shortwave listener most of the time, so I’m sure some other reviewers will go into much more detail on the Shortwave performance of this radio then I will. My experience tuning around on Shortwave with the D-328 was similar to AM, in that I had a lot of unexpected surprises in strong signals between 6900KHz and 9300KHz. My shortwave listening usually takes place on digital tuning with the Tecsun PL-310ET, so it’s hard to compare analog listening for something I don’t do that often. Tuning was surprisingly easy on the shortwave bands, but seemed frustratingly random where stations would show up.

MP3

Let’s get this out of the way immediately – this radio does not record MP3 files. Instead, sliding the mode selector to “MP3” will let you play files off a “TransFlash” (MicroSD) Card.

I’ll be up front here – this radio is a functional, but not fun to use MP3 player. I tested the MP3 player by loading up a 2GB MicroSD Card I had laying around with some files in a structure similar to the following:

* Root

** File1

** File2

** Folder1

*** Subfolder 1

*** File 3

*** File 4

** Folder2

** File 5

** File 6

** File 7

The first thing you’ll notice when playing MP3s is the “MP3” Light that is Red. And blinks. And blinks. Yes, the red light blinks continuously while playing an MP3 file and you can’t turn it off. This right here would annoy me to no end if I wanted to use this feature

My second problem with using MP3 functionality is that playback without a screen is a throwback to the days of the iPod Shuffle. And if this radio had “shuffle mode”, I’d be OK with that, heck that would even be fun – but there’s no shuffle here, only sequential play.

This radio does seem to follow the expected order of my files in playing them sequentially 1 through 7 across subfolders, but the lack of visual feedback makes it very easy to forget where you’re at and what you’re playing. Pressing and holding the fast forward button does work to fast forward, and rewind through individual mp3 files.

If you want to load up a MicroSD card with some old time radio episodes and play them back – this might be great. But I’d probably ask you why you’d ever want to play MP3 files on this thing. I mean, the feature is there…. But why? There’s much better devices and experiences out there for MP3 Playback rather than loading files onto a MicroSD card to play on a device with no screen. I imagine this might have some utility usages for playing MP3’s when you don’t want to sacrifice more expensive hardware, but I personally can’t see myself getting much usage out of the feature.

Conclusion

At the end of the day I have to ask myself – who exactly is this radio for? The price point and feature set seems to pit this against the very low-end of the AM/FM/SW Market such as the Analog Tecsun R-9012 at $22, and Tivdio Digital tuning units around $18. The inclusion of Shortwave, Mp3 Playback, and USB rechargeable battery gives this a leg up over budget AM/FM units, as well as the competitors mentioned.

Is the DX/radio hobbyist the target market for this radio? I don’t think so. While cheap (and we Shortwave/HAMs are a cheap bunch!), this radio lacks the sophistication or features a DX’er would want.

Is this a good “throw-away” radio for when you don’t want to risk your “Good” Radio? Absolutely. I would not hesitate to toss this in a coat pocket, keep it out in the garage / workshop, or give it away to a friend. My personal use case for this radio will probably end up being I’ll take it to Baseball games to listen to the game on AM / FM while watching the game. If it breaks, I wouldn’t be too sad and would likely shell out another $14 without hesitation for a replacement.

Is this radio for kids? I don’t think so. Given the poor build quality of this, I can’t imagine this lasting very long in a youngsters hands and surviving more than a drop or two. Analog tuning is likely to prove incredibly frustrating to a youngster, and I can’t see anyone but the geekiest of little geeks making use of the MP3 player function.

Would I use this as an emergency radio, shoved in “go-bag” or kept around for winter storms / hurricanes? Probably not. The build quality and lack of standardized AA-Batteries would give me concerns over my ability to power it (though it did work great from a USB PowerBank when I tested) More concerning is I don’t know if I would trust this to still be working when I need it in a stressful situation.

So who is this for? This radio seems more destined / designed for the low-income international market. The price point on this radio is certainly attractive to North American buyers, but I just don’t think the average American radio buyer really wants or needs MP3 MicroSD Playback or Shortwave functionality.

For $14 XHDATA has made good, but not great, little radio. My future suggestions would be:

Ditch the MP3 functionality – it’s of marginal usefulness
Seal off the wrist-strap loop hole better
Fix the case design so the antenna can sit more “upright”, and swing more freely.
Re-design the kickstand to run the entire length of the radio, possibly doubling up as the battery door if somehow possible
Switch from Mini-USB, to Micro-USB connector
The BL-5C Battery is an …. Interesting choice. It sure seems to help with weight, but I think I’d rather see a single 18650 Cell as hinted by the manual or AA’s.

Many thanks, Aaron, for sharing your fine evaluation of the XHDATA D-328! I couldn’t agree with you more regarding your “future suggestions”–sounds like the MP3 functionality has marginal utility and the chassis design could use some tweaks. I’m very surprised a radio made in 2018 still uses a Mini-USB port. And that kickstand? I don’t think I’ve ever seen one more off-center!

But as you conclude, for $13.80 US (Amazon affiliate link), it is a very inexpensive unit. Not one for the radio enthusiast, but one that could please the casual radio listener. It sounds like the audio is surprisingly robust.

Thanks again for your fine review, Aaron!

Many thanks to SWLing Post contributor, Aaron Kuhn, who writes:

Another “Radio in Popular Culture” tidbit for you since they seem so popular:

2014 war survival game “This War of Mine“, released on multiple platforms, features a simulated shortwave radio you can build and use as part of the game.

After building the radio from components/parts you find, it allows you to use the radio on a daily basis to gather intelligence about what’s going on out in the streets around you.
