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.

A Nutty Idea

XHDATA D-220 available in three colors

By Jock Elliott, KB2GOM

Official Disclaimer: “Yes, XHDATA is a supporter of the SWLing Post but this is my own crazy idea, and we aren’t getting any commissions from the sales. XHDATA doesn’t even know we’re doing it!”

It’s all Robert Gulley’s fault. He had the temerity to post an article about the XHDATA D-220 entitled “A Throwback to a Simpler Time” —  I read it, was intrigued, and ordered one.

It arrived today, and, by golly, it actually works. I snapped a couple of AA cells into the battery compartment and discovered immediately that it appears to have a pretty hot FM receiver section. Then I tried medium wave and pulled up several of the local AMers. Then, the acid test: shortwave. Robert Gulley was right: “you will want to turn the dial slowly, very slowly.” But, sonuvagun, if you use a safecracker’s touch, you will actually discover and receive distant shortwave stations on that dinky telescoping whip antenna . . . with an exceedingly inexpensive radio.

So here’s my Nutty Idea: How about an XHDATA D-220 DX contest?

Rules:

  • You must use a D-220 with native antenna
  • No use of other radios or SDRs as “spotter” radios.
  • You must ID off the air.

As Thomas, our Maximum Leader, put it: “It’s so insanely cheap, it’s a great way to have everyone on a level playing field. Well, unless someone gets the yellow version which we all know has special powers.” (Yes, I bought the yellow version.)

Further, I proposed we kick this thing off at 6 pm your local time on Friday, August 16, 2024 and it ends at 6 pm your local time on Sunday, August 18, 2024. You log the time, the estimated frequency, the station ID and what you heard. There are no prizes, just bragging rights. The object: to have fun!

So, whaddya think?

Or should I go back to the home and start taking my meds?

Dan Robinson Reviews the New Tecsun S-2200X Portable Receiver

Many thanks to SWLing Post contributor and supporter, Dan Robinson, who shares the following review:


Tecsun Delivers The S-2200X – New Life For A 16-Year-Old Cabinet Design

by Dan Robinson

Note: Please see an addendum of updates at the end of this post.

Some months ago, I learned from Anon-co that Tecsun planned to release an update to the S-2000 receiver, which for the past 16 years also sold under other names such as the Grundig Satellit 750 and later the Eton Satellit 750 and Eton Elite 750.

To say that this radio was long in the tooth is an understatement.

I remember seeing one when they first came out back in 2008 and I was never very impressed.  To me, the radio looked like a toy, and the performance did not impress.  The standout feature was the top-mounted rotatable antenna for MW/LW reception.  That was popular with those of us who own the Panasonic RF-2200 and it’s a great tool for MW.

Grundig Satellit 750

While popular with a certain segment of the listening hobby – beginners liked the 750 and even some veteran SWLs appreciated the retro design — the receiver was plagued by annoying issues, such as the famous wobbly tuning knob.  It also had limited selectivity, no synchronous mode, and mediocre SSB.

In 2013, The Monitoring Times (Larry Van Horn) took another look at the radio with the following memorable comments:

[MONITORING TIMES 2013]

“Needless to say some folks were not happy with our review of the 750 including Etón. In retrospect, over four years later, I would not change one single word I wrote in that review.  I believe we honestly gave a fair assessment of the unit that was shipped to us for review. If you read my previous review closely, you would see that most of my concerns back then had to do with quality control issues and most in our industry fully acknowledge that we were seeing some nasty stuff coming out of China back in 2008.”

So, measuring from 2008 when the first Eton 750 came out we’re now in 2024 and Tecsun has decided to preserve the cabinet design of the original radio while substantially upgrading the internals.

Enter the S-2200x

Reviewers have obtained units from the first production run.  Tecsun has provided long-needed upgrades that put this radio on the same playing field as the very popular H-501 and PL-990 portables.

The 2200x adds a dedicated SYNC mode with its own front panel button.  AIR band is retained, though sadly coverage doesn’t extend up to give us the NOAA WEATHER frequencies.

My initial testing of the S-2200x shows that performance is excellent on SW, AM, and FM.  In contrast with portables from other manufacturers, SSB performance is excellent – in USB and LSB, tuning is smooth with no “warbling” and using the fine tuning control is a pleasure. Continue reading

XHDATA D-220 available in three colors

XHDATA D-220 – A Throwback to a Simpler Time

By Robert Gulley

XHDATA recently contacted me about a new portable radio, saying “XHDATA is planning to launch a new portable radio, the D-220, which has good reception and excellent sound quality. Not only can it receive FM/MW/SW bands, but the price will be surprisingly good value.”

Okay, well that sounded somewhat interesting (especially the bit about being “a surprisingly good value”). So within a few days I had a pre-release copy of the radio after choosing the color I preferred (black – what can I say, I am a traditionalist!).

The radio is small, 5” tall, 2-1/2 inches wide, and about 1 inch thick, very reminiscent of my first transistor radio in the (ahem) 60s. It has an analog tuning dial, volume control, and slider switch to go between FM1/2, MW, and SW. It also has a headphone jack. It takes 2 AA batteries (very old school!), and, unlike my transistor radio of old, a swing-out stand. That’s it. And, interestingly enough, that’s all it needs.

As my wife and I like to say about life sometimes, “It is what it is.” And, unlike life so often, in this case that’s a good thing. The radio is simple to operate – no menus, no bells and whistles, just the basics. You, an antenna, and a tuning dial.

For some, the tuning dial will be an aggravation, because just like my transistor radio of old, the tuning dial covers a lot of ground in a relatively short rotation. This means you will want to turn the dial slowly, very slowly. While this does not bother me, I realize this may not be everybody’s cup of tea. To get the best reception out of this radio, you need to turn the dial in millimeters, not even fractions of an inch.

Fortunately, the tuning dial is very firm and yet responds well to a light touch. I had no problem tuning between stations, even on a very crowded FM band or on a tight SW band covering 5.6 to 22MHz.

As for reception – well, I was rather surprised by this little radio. AM and FM delivered many, many stations in the rural area which I call home, and the biggest surprise was the shortwave reception. I waited until I had a storm-free evening (not always easy this summer here in the Midwest), and fired up the radio expecting to hear some of the more powerful stations, but not expecting to hear a large number of stations 10MHz and below on such a small (10-1/2”) antenna.

Speaking of the antenna, it is solid and one of the better antennas I have found on this size of radio. Yes, you can break it I am sure, but flimsy it is not. The same goes for the battery door, it closes with a resounding “click,” and I do not believe one could open it unintentionally.

As for the sound, it is surprisingly clear, and loud. One of the advantages of modern radios is smaller components, which in turn allows for bigger speakers. This speaker punches above its weight class for both talk radio and music. Both sound good with a reasonable signal.

As the radio has not been released to the general public yet, the XHDATA website does not have a listing for the radio, and therefore no price information. However, and this is a bonus for those of you who have read this far, Thomas’ readers will be eligible for a 40% discount when the radio becomes available for sale from XHDATA, the current projection being sometime in August. They will send out a shopping link and discount code when available.

Pros

  1. Great sound
  2. Solid antenna
  3. Impressive reception on all bands
  4. Analog dial tuning, solid and easily turned slowly (see Cons)

Cons

  1. Very tight tuning dial with little space between stations (see Pros)
  2. Not available quite yet

 

Conclusion

This is a solid little radio you can carry in a shirt pocket or jacket pocket easily, and since it runs on AA batteries with no significant draw of power, should provide hours and hours of enjoyment. The addition of the shortwave band, along with its decent reception, is a nice bonus, especially since I prefer SW to most anything I hear on MW and FM (wait, did I say that out loud? Oops!).

I suspect this will be a good radio to put on your to-buy list, especially with a 40% discount!

Radio Waves: Switzerland to End Analog Radio, AM For Every Vehicle Act, AM v Safety, and Electromechanical Radio Transmitters

Radio Waves:  Stories Making Waves in the World of Radio

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 and Dennis Dura for the following tips:


Switzerland to end 2024 with an analog FM broadcast-killing bang (The Register)

Time to upgrade that receiver if you’re one of the few Swiss that still don’t have one able to receive DAB+ signals

Swiss radio listeners will soon have to toss out their old sets, as the country plans to end analog FM broadcasting on December 31, 2024, in favor of a total conversion to digital.

The move has been a long time coming in Switzerland, which has largely already transitioned to Digital Audio Broadcasting (DAB+, an evolution of standard DAB that was designed to address early issues). More than 99 percent of the country have access to a DAB+-compatible receiver and fewer than 10 percent of radio signals in the country still being broadcasted in analog FM, according to the Swiss Broadcasting Corporation.

AM Radio for Every Vehicle Act to Receive Minor Technical Update (Radio World)

There will be no substantive changes to the legislation

A bill in the House of Representatives that would mandate AM capability in new vehicles is about to be revised, according to a person familiar with the developments.

New information indicates that one of the original co-sponsors of the bill, Rep. Frank Pallone (D-N.J.), plans to introduce an amendment to the bill (H.R. 8449). Changes would only include minor technical updates.

The planned amendment to the AM Radio for Every Vehicle Act comes on the heels of last week’s last-minute cancellation of a planned vote by the House Energy and Commerce Committee, which could have advanced the legislation to the full House for a vote. [Continue reading…]

Would AM Mandate Force Carmakers to Scrap Safety Features?

Opponents play up the possibility that carmakers would have to choose

If Congress requires AM radio in new cars, vehicle manufacturers might have to drop safety features instead.

That’s the message from opponents of the proposed law in Congress. A guest commentary published by Automotive News restates the key points that opponents have been making since the legislation was introduced; but their blunt emphasis on a possible tradeoff with important safety features seems notable.

“To accommodate analog AM radio as a primary design requirement, certain carmakers may need to scrap advanced safety features, with engineers having to prioritize outdated technology over current or future safety innovations,” they wrote. [Continue reading…]

Did you know that 100 years ago there were electromechanical radio transmitters?

Many thanks to Paul who shared a link to this Mastodon thread discussing the technology behind the SAQ/Grimeton broadcast station: https://mastodon.social/@tubetime/110970146022678448

Here’s is a video (we’ve posted in the past) that gives even more detail about the design and operation:

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.

“Music On The Move” explores portable audio technology developments over the decades

Many thanks to SWLing Post contributor, Ed, who writes:

Last night on my bedside radio I heard on BBC World’s ‘The Forum’ a wonderful 49-minute piece about portable audio. Much of it covers the earliest portable electron tube radios and transistor radios, and their influences on society in different countries. Mediumwave, Shortwave and FM radios and stations are discussed, as well as evolving technologies. The societal impact of the Compact Cassette and digital audio players and recorders is also discussed. Probably all SWLing Post readers will find this worth listening to!

Cheers,

The Forum: Music On The Move

Released On: 22 Jun 2024

Many of us remember the first portable music device we owned: a transistor radio, a boombox, a Walkman or perhaps an iPod. We might even recall the songs we played on it. But we might be less aware of how profoundly audio technology developments from the 1950s to 2000s changed the ways in which we consume music and other audio outside of the home or concert venue. Transistor radios allowed outdoor sounds and noises to mix and compete with those coming over the airwaves, creating new auditory experiences; the cassette player gave the listener a cheap way of making and re-making their own playlists; and the advent of digital music players encouraged us to ‘own’ music recordings without possessing a physical copy of the audio.

Iszi Lawrence discusses the history of portable music with Dr. Annie Jamieson, Curator of Sound Technologies at Bradford’s National Science and Media Museum; American drummer and writer Damon Krukowski; Dr. Jahnavi Phalkey, science historian and Founding Director of Science Gallery Bengaluru, India; Karin Bijsterveld, Professor of Science, Technology and Modern Culture at Maastricht University; and World Service listeners.
