TWR’s Bonaire Facility Gets 440,000 Watt Makeover

In an era when most operators are reluctant to spend even very modest sums maintaining AM broadcast facilities, a southern Caribbean Island medium-wave broadcaster has “gone for the gold,” rebuilding its transmission facility and boosting power nearly five-fold from 100 kW to 440 kW.

The rebuild was more of a “second coming” for the 800 kHz facility, located in Bonaire, an island that is part of The Netherlands, situated about 100 miles off the Venezuelan coast. The station is owned and operated by Trans World Radio, one of the world’s largest evangelical media organizations.[…]

On the eve of the 2018 Hamvention, we review the 2017 Hamvention

Later this week, I’m looking forward to attending the 2018 Hamvention in Xenia, Ohio. Hamvention is always a highlight of my year.

Last year, the Hamvention moved to their new location at the Greene County Fairgrounds in Xenia, Ohio.

As the 2018 Hamvention quickly approaches, I’ve been asked by a number of readers and friends what I thought about the new location. No doubt, many are trying to decide if the pilgrimage will be worth it as they live several hours drive, or a flight away.

Last year, I was asked to give a report of the 2017 Hamvention for The Spectrum Monitor magazine. I realized I never shared this report on the SWLing Post, so I thought I’d do so now, just a few days before Hamvention commences.

In the past year, we’ve received several updates from DARA who host the Hamvention.  I’ll include updates at the end of this piece.

Note that the following article first appeared in the July 2017 issue of The Spectrum Monitor magazine:


2017 Hamvention Report

When the ground was dry, the flea market was accessible and offered some of the best diversity this treasure-seeker has seen in years.

The long-anticipated 2017 Hamvention in Xenia, Ohio has now come and gone. As with each year of the Hamvention, what I enjoy more than anything else, along with learning about all of the latest innovations in our dynamic hobby, are the people: old friends and new, old friends and young. And of course, I also love browsing the flea market for vintage treasures!  But this year, the relocation of the Hamvention drew many who wanted to see how a new venue might improve, impede, or simply change the event, and I was also among these.

Many have asked about my experiences at the Greene County Fairgrounds–the new Hamvention venue–so I thought I’d offer an overview of the experience.

But first, a little history.  For decades, the Hamvention––the largest gathering of ham radio operators and enthusiasts in the world––has been held at Hara Arena in Dayton, OH, hosted by the Dayton Amateur Radio Association (DARA).  But Hara’s owners folded their business last year [2016], resulting in DARA’s immediate need to relocate the event. Since many national and international vendors risk big bucks to attend, and since comparable events in, for example, Germany and Japan take place in sleek, modern venues, expectations for a new venue were somewhat elevated.

So last year when DARA announced the Hamvention would now be held at a county fairground in the small town of Xenia, OH, many were surprised, and a number expressed concern. DARA assured vendors and attendees that the Greene County Fairgrounds was up to the challenge.  Regardless, the shift was certain to bring the unexpected. In truth any event that hosts 25,000 – 35,000 attendees will be a complex endeavor to organize, and that the Hamvention is also subject to this complexity became obvious as the weekend unfolded.

Hamvention has always attracted a large international amateur radio crowd.

In years past, the experience of most Hamvention attendees, exhibitors, and flea market vendors is likely to have been similar.  Hara Arena had been deteriorating for years while adequate maintenance of the facility seemed indefinitely deferred, so if you asked the average Hamvention attendee what they thought about Hara Arena as a venue, the reply might have been, at best, “Meh.”

Yet, the event continued:  for, though Hara had many issues, the venue did manage to house the entire Hamvention crowd on one site, and––especially important to those with limited mobility––on one level. And fortunately the Hamvention is limited to only three days, so repeat attenders were likely to have mastered the requisite survival techniques for Hara. Even during rainy spells, the event attracted large crowds, and the outdoor flea market endured even mud since it was held on a large broken asphalt parking lot. (Yes…I am conveniently overlooking the year a pond of sewage bubbled up in the parking lot during the flea market…True story).

But problems continued to, um, surface, and it seems inevitable that the owners finally decided to call it a day.  No doubt, Hara’s days as a Hamvention venue were numbered, particularly because the dilapidated infrastructure continued aging without the the necessary reinvestment to keep it current––or even safe.  Moving the Hamvention was now the only option.

Xenia Fairgrounds: A “Five-Star” Facility–?

Despite Hara’s shortcomings, many worried that a fairground didn’t seem like much of an upgrade. Still, DARA representatives gave assurance in numerous video interviews as well as at the W4DXCC conference that the Greene County Fairgrounds would make for a “five star” event.

Now that the 2017 Hamvention has been and gone, was it a five star event?

Honestly, I think the answer would depend on your perspective as either an attendee, an inside exhibitor, or a flea market vendor.  To be fair, let’s look at some of the key areas that make or break large conventions like the Hamvention, and what conditions were like at this new venue.

Traffic

 

The fairgrounds are essentially located in the middle of a neighborhood. The roads leading in offer two lanes with two-way traffic, not designed to handle vast amounts of traffic.

Hamvention organizers worked with specialists to sort out the flow of traffic into the Greene County Fairgrounds. No doubt, it was a complicated feat.

If you attended Hamvention on Friday as an attendee, you were likely upset with how long it took to make that last mile to Hamvention. Several folks told me it took them almost one and a half hours to move the final 1.3 miles to enter the fairgrounds and park. Most folks who came that morning were naturally frustrated by this, and many were quite vocal about it.

Friday evening, with the aid of Greene County Sheriff Gene Fischer and the local public service team, the traffic flow team sat down to hammer out a plan, and the traffic issue was almost magically resolved. I heard no complaints about traffic on Saturday or Sunday. Great job, folks!

Parking

If it had been a dry, sunny weekend, I think the average attendee would have been pleased with Hamvention parking.

Sadly, as it was not. Herein lies the greatest negative about the new location: mud. Lots of mud.

While there were satellite parking lots with buses that ferried people to the event, many attendees, perhaps most, parked on the fairgrounds grass lots. The fairground fields are vast and hold lots of cars, but they are almost completely grass-covered.

Many Hamvention visitors expressed concerns last year about the ability of the fairgrounds fields to handle the incredible amount of traffic of Hamvention, should it rain. We were reassured that the fairgrounds were well-drained and that the grass could handle the traffic. After all, they do hold fairs, and it had never been an issue.

Unfortunately, the Hamvention weekend was punctuated with periods of heavy rain, fairly typical in spring. Both Friday and Saturday, it was largely sunny and the rain only lasted a quarter of an hour or so, but during the night storms passed through.  The grounds were already somewhat saturated, so any additional rain resulted in––you guessed it––mud. Lots and lots of it.

In short: if you parked at the Greene County Fairgrounds on Saturday, there was a good chance you might have gotten stuck in the mud. And the mud was truly thick, slippery, and nasty, designed to make locomotion difficult. At one point, I ventured into the parking lot and managed to tour it on a golf cart. I saw no less than two cars being towed out of deep mud. One, in fact, had sunk to the point it appeared to be floating on a sea of mud. During this time period, it was not only difficult to park your car upon arrival or to get your car out of the parking lot upon departure, but it was challenging to simply walk in the parking lot, or skirt around the deep muddy areas to enter the main gate.  For those with disabilities, it must have been near impossible.

In short: because of the rain, parking on site on those days was pretty undesirable.

I’m not sure how DARA will sort this out next year, but I imagine it will involve numerous satellite parking lots if weather is bad.  Gravel would be good, too.

In contrast, as an inside exhibitor, I was very pleased with parking on all three days. We had a separate entrance with dedicated staff, and parking was close to the buildings where we had to set up each day. We had the advantage of parking on hard-packed gravel. It was a much better arrangement than the days of Hara Arena, even. All of the inside exhibitors I spoke with were pleased with parking.

But I felt truly sorry for attendees parking in the field.

Flea Market

Like the on-site general parking, the flea market was on the grassy fields of the fair grounds. Due to spongy wet ground and the number of heavy vehicles full of gear that had to enter and leave each day, even as early as Friday morning it was clear it was soon going to be a muddy mess.

he mornings and after periods of rain made moving around the flea market quite challenging for some attendees and vendors.

Friday morning was indeed muddy, but Friday afternoon, the sun came out and dried out much of the mud. It seemed a lucky break.  That is…until a late afternoon thunder shower soaked the saturated ground again.

The water table just couldn’t hold it all.  So, Saturday and Sunday…? It was unfortunately  muddy all day.

Even the golf-carts manned by volunteers to help attendees ferry heavy purchases back to their cars could not enter many of the flea market paths for fear of getting mired down. Personal mobility scooters really had a difficult time, and many got stuck. I don’t think the bulk of the flea market was accessible to anyone in a wheelchair.

In short, I imagine most flea market vendors were frustrated with the mud.

This being said, I must say that the selection of goods at the flea market was even better than I’ve seen in previous years. If it had been a dry weekend, it would have made for very pleasant gear goggling and treasure hunting.

Inside Exhibits: Steel-Framed Agricultural Buildings

Taken during setup the day before the Hamvention opened to the public. Note the healthy amount of space between vendor tables.

Though I was a bit skeptical about the fitness of the large metal-framed agricultural buildings for inside exhibits, I was pleasantly surprised: these buildings are large, clean, well-lit, with an open, airy feel. Much better, in short, than most of the spaces at Hara Arena.

All of the inside exhibitors I spoke with were, in general, pleased with these buildings. They were also pleased with the spacing between booths which allowed for improved traffic flow. There were a few complaints about outlets hanging from the ceiling, a feature likely used when the building is in service to show livestock.

Inside exhibitors were overall very pleased with the steel buildings at the Greene County Fairgrounds.

A few vendors felt it got a bit toasty indoors in the middle of the day when the sun made a cameo appearance. Still, I got the impression that most attendees felt the buildings were well-ventilated and relatively cool, and overall, an upgrade on Hara.

Inside Exhibits: Event Tents

The large, white event tents did house a large number of vendors.

Because there were not enough permanent buildings on site to house all of the inside exhibits, DARA arranged for a large events tent––labeled “Building 6″–– to house all of the extra booths and tables. Many of us believed this could be a great alternative.

However, I heard that very late in the game, DARA was informed that the large tent they had on order fell through. They had to find a last-minute alternative, which ended up being three smaller (though still large) event tents arranged in close proximity.

The interior of the large vendor tents were rather dark. Note the light penetrating the tent seams. This shot was taken before vendors had set up.

The booths in the tent were not marked or numbered in advance, so this lead to a lot of confusion for both vendors and (later) visitors.  Adding to the confusion was the relative darkness of the interior of the two long tents.

Later, during a series of thunderstorms that produced a lot of wind, it became obvious that the replacement tents also didn’t have adequate sand-bagging to hold down the side walls, which began flapping quite violently.

The darkness of the interior of the two long tents was mitigated slightly by some decorative  globe lights hanging from the center poles of the tent, but these provided very little in the way of lighting. When it was bright and sunny outside, it wasn’t too much of a problem, but when it clouded over, as when the thunderstorms passed through, it became very dusky and dim, indeed.

During periods of rain, the tent vendors and attendees had to cope with water.

The worst problem by far in these tents, however, was water penetration.  The tent ceiling and seams were littered with holes. So, during downpours, water would shed off the sides of the tent then enter the perforations, raining down into the tents and forming minor rivers on the asphalt en route to the drains. Significant water in the presence of so many electrical drop cords became a rather risky shock hazard.

During rain, tent vendors had to either move their displays…or just get wet.

It’s telling that not a single tent vendor that I spoke with was pleased with their site.

I spoke with a DARA representative about this, and he was very apologetic:  clearly, DARA was not at all pleased with the last-minute tents. One of the volunteers I spoke with told me that as early as next year, there may be another permanent agricultural building or two to house all of the vendors that were in tents this year. This could be an excellent upgrade, and I do hope, should the Hamvention continue at this site, that it comes to pass.

Hamvention Staff

The Hamvention volunteer staff were incredibly helpful–and there were a lot of them, as well.

I spoke with so many vendors who were also very pleased with the on-site security. These folks were friendly, helpful, and customer-focused. Thank you, volunteers!

Food

The outdoor food court was spacious and offered some excellent choices.

No question: the concessions were better this year than any previous year I’ve been to the Hamvention. I heard compliments all weekend. Excellent job, food service staff!

Forums

Hamvention forums were held in a dedicated, large air-conditioned building. The forum space was much better than that at Hara, and I expect most attendees were pleased.

Summary

If I were doing a review of the Hamvention structured like one of my radio reviews, I’d summarize the experience with these pros and cons:

Pros:

  • Friendly, helpful staff––especially considering the weather and other challenges
  • Excellent attendance
  • Compact layout (compared with Hara)
  • Permanent buildings allowed for easy traffic flow between vendor areas (compared with most of Hara’s spaces)
  • Adequate, clean restrooms and port-a-potties compared with Hara; very few lines
  • Concessions of great variety and accessibility
  • Steel-framed agricultural buildings were clean, comfortable, well-lit, and airy
  • Traffic flow to on-site parking improved on Saturday and Sunday (see “con” re Friday)
  • Steel-frame building exhibitors seemed to enjoy improved sales numbers

Cons:

  • Frustratingly slow traffic flow to on-site parking on Friday (see “pro,” Saturday and Sunday)
  • On-site parking exceedingly wet and muddy (following rains)
  • Flea market paths too muddy in wet weather, inaccessible or problematic for those with limited mobility
  • Vendor tent booth spaces unmarked, leading to vendor confusion during set-up
  • Vendor tents inadequately lit
  • Vendor tents leaking and therefore unsafe when rain water entered, contacting electrical equipment
  • In metal-sided buildings, interiors could be hot when ventilation fans weren’t in use

So, the upshot?  Whether or not you enjoyed the new Hamvention venue in 2017 probably depended on who you were:

If you were an attendee on Friday, other than coping with traffic to the site, you were likely pleased with your experience at the Xenia 2017 Hamvention. By noon or so, the ground had dried up and most of the flea market was accessible; it wasn’t until late afternoon that it began raining.  If you were an attendee during or following the rains, or on Saturday or Sunday, you may have enjoyed the event, but were likely quite frustrated with the mud.

If you were a flea market vendor, no doubt, you were frustrated with the mud, which dramatically decreased foot traffic.

If you were a tent vendor, you were likely frustrated with the poor lighting and water penetration–all of which affected customer traffic, especially during rain.

If you were an inside exhibitor in one of the permanent agricultural buildings, you may have had the best sales, traffic, and overall Hamvention experience in decades. Most inside exhibitors I spoke with were very pleased with the facilities. I spoke to at least four major vendors that experienced record sales.

Moving forward…

While I’m not sure this year’s Hamvention can claim “five stairs,” I’d offer five stars for effort, and for improving upon Hara in a number of respects.

Many thanks to all of the volunteers, staff, and attendees that helped create a terrific Hamvention despite its inevitable bumpy, muddy course following relocation.

Obviously, lessons are to be learned from the 2017 Hamvention.  Thoughtful consideration of this year’s problems are sure to benefit next year’s Hamvention if Xenia is to continue as its new home. I’ve written this review in hope that the stewards of the Hamvention will take this feedback in the positive spirit in which it’s intended, so as to improve upon the experience for next year’s Hamvention.

Since traffic flow was sorted out Saturday and Sunday, to the great credit of those who reorganized it, there are really two main areas that truly need improvement: mud/water mitigation (yep, that’s a big one), and better accommodation for this year’s exhibitors that were in tents.

Moreover, I think it’s essential that DARA provide prompt feedback and updates to those attendees and vendors who had frustrating experiences, reassuring them that their concerns were heard, will be addressed, and that circumstances will indeed improve next year.

But ultimately, the Hamvention belongs to the entire ham radio community.  We’re radio folks, which means we listen, we communicate, we design, engineer and build––just the qualities needed to help make the relocated Hamvention even better. So, let’s ask: what can we do to help?

Let’s show up again next year with renewed vigor and a commitment to make the 2018 Hamvention a six-star event!  As. of course, we can.


Updates

Here are the latest updates from DARA regarding improvements to the 2018 Hamvention:

Inside exhibitor space

In December 2017, DARA announced plans to add an additional prefabricated metal building to house most of the inside exhibitors that were in tents last year. DARA then made the following announcement in February 2018:

Despite all of the best efforts and intentions by Greene County, the Greene County Agricultural Society and Hamvention, we have learned the anticipated new building will not be constructed in time for Hamvention 2018. The prefab sections bid on and architecturally required are currently backlogged. We expect construction to be delayed until after our show and the Greene County Fair. We expect completion of construction yet this year and ready for our use in 2019. We regret this; however it is well out of our control.

We will have increased Inside Exhibits space with the addition of the vacated Furniture Building.

DARA conducted a lottery to pick vendors who would get a space in the vacated furniture building.

I also spoke with the Inside Exhibitors coordinator early this year–he said they hope to use a different tent vendor this year.

Mud mitigation

As I mentioned above, mud was a serious issue last year–making both parking and flea market access problematic.  In February 2018, DARA noted the following improvements:

After consultation with professionals, we are in the process of solving the mud issue in the Flea Market area. We anticipate work to start as soon as weather allows.

We are rearranging the soccer field parking to eliminate use of the low areas where we had problems last year. We will also have a revised exit plan.

Additional offsite parking will be available, along with easily used maps to help you navigate. Transportation from parking areas to the show will still be at no cost.

I understand they’re also making more satellite parking areas available to keep the amount of visitors parked onsite to a minimum–this would also help with traffic congestion. An Inside Exhibitors team member also mentioned that they may take measures to regulate the amount of foot traffic going through the main gate to help mitigate mud; possible making a secure space to hold heavy purchased items.

The latest long-term forecast at time of this posting (on Monday, May 14) shows a chance of rain for Friday and Saturday of Hamvention:

This forecast is four days out, however. With any luck, perhaps we won’t have the thunder showers we had last year. If the fairgrounds remain dry, many of DARA’s problems will be solved.

I’ll be bringing my Wellingtons anyway.

Of course, as I do every year, I’ll take hundreds of photos at Hamvention and post them here on the SWLing Post during the event. Stay tuned!

A review of the supercompact Sangean WR-7 FM Radio and Bluetooth speaker

Folks have been known to say that good things come in small packages.  And, do you know what? They’re sometimes right. [Spoiler alert: This review features a good thing which comes in a small package.]

I’ve been in the process of evaluating some pretty complicated pieces of communications equipment lately. So when Sangean approached me a few weeks ago and asked if I would check out their latest FM radio and Bluetooth speaker––a comparatively simple piece of kit––I thought, Well, why not? Because while I prefer “enthusiast grade” radios, sometimes it’s nice to check out something super-simple and purpose-built from a company I’ve grown to trust. Plus, it didn’t hurt that Sangean actually bothered to include FM radio on what would otherwise simply be just another Bluetooth speaker.  Ah, yes; a worthy addition.

Sangean dispatched the sample radio and I received it within a few days. I was expecting something roughly on the scale of a Tivoli Model One.  Instead, when I opened the box, what I found was a radio only slightly larger than my diminutive  Muzen OTR, a little radio that fits the palm of your hand. To be fair, it could only be called…cute.

By my measurements, the tiny Sangean WR-7 is about 2 1/2″ tall, 4 5/8″ wide, and 3″ deep (if you include the tuning knob in that last dimension). It’s mini by almost any standard.

For this photo I placed it next to my handy XHDATA D-808 compact radio.  And here’s how they compare:

Though wee, the WR-7 feels weighty (14.4 oz), solid, and substantial in the hand.

Turns out the chassis is solid––solid wood. Sangean has two options: walnut and dark cherry. Of course, my sample is a black version which may appear later in the year.

And the WR-7 is as simple to operate as it is to…well, hold in your hand. There’s one knob to turn the radio on and select the source (FM, Bluetooth, or the analog AUX input), and another knob for volume.  Just as these photos show.

The tuning knob is the largest knob and moves fluidly across the dial. The analog dial is white with black frequency markings, and is backlit. From my tests, the FM dial is fairly accurate, although the frequency marking steps are a bit odd: 2 or 3 MHz increments starting at 87.5 and ending at 108 MHz.

There is a green LED lamp hidden behind the speaker grill that acts as the FM signal strength indicator. This LED turns blue when in Bluetooth mode.

Performance

There’s not a lot to report on here and, perhaps, that’s why I halted my other evaluations to fit this one in. This radio needs no owner’s manual (though it does ship with one). All you need is a USB charging cable––yep, the same type that likely charges your mobile phone.  And, of course, it ships with one. It also ships with a lightweight cloth-like carrying bag.

You might have noticed that the WR-7 doesn’t have a telescoping whip antenna.  That’s okay, because it also ships with an external wire antenna (which I actually prefer on this type of mini tabletop radio).

The WR-7 has an internal 2600 mAh Lithium-Ion Battery that provides this tiny rig with up to 36 hours of operation between charges. While I haven’t tested this claim yet, I can tell you that its battery life is incredibly good––especially acknowledging that the audio amplifier must be using quite a bit of the battery.

FM

The WR-7 receives the FM broadcast band from 87.5 to 108 MHz.  While the dial is analog, I know there’s a DSP chip inside because I can hear frequency steps while I tune across the band. There is no muting between frequency steps, so the experience of tuning feels somewhat analog. As I mentioned earlier, the dial layout is a little quirky, but overall the frequency markings are pretty close to accurate. I found my benchmark stations with little difficulty.

In terms of sensitivity, the FM receiver is quite good in the WR-7.  I could receive almost all of my local stations with the external FM antenna connected. Of course, you’ll want to connect the FM wire antenna.

With the external antenna connected, I could receive all of my benchmark distant and weak stations as well on the WR-7. While reception is very good, it isn’t quite as good as on my XHDATA D-808, C. Crane CC Skywave SSB, or Tecsun PL-660––the lock isn’t quite as stable––but I probably could have tweaked this by moving the external wire antenna.

Audio fidelity

Thing is, with even a decent FM signal, you’ll be mighty impressed with the audio fidelity of the WR-7. It easily manages to sound like a radio three to four times its size. Truly, the bass that emanates from this tiny speaker is incomprehensibly deep–only limited by the size of the acoustic chamber.

The sound is rich and room-filling when the volume is turned up.

And speaking of turning up the volume, this is one little radio you’ll probably peg at its highest volume setting from time to time. In fact, I rather wish this radio would allow the volume level to reach even a notch higher…but I expect this was a design choice at Sangean. With the volume turned up all the way, the sound is room-filling, but not distorted. While testing the WR-7, I tuned it to a variety of stations and played a wide range of music through it via Bluetooth: I never noticed bass-heavy songs distorting the audio. I suspect if the volume could be increased even further, the audio would indeed distort a bit.

In short: though you might occasionally turn up the volume on the WR-7 all the way, you’ll be pleased with the results––even across the room!

Bluetooth

I’m not sure what to say about Bluetooth; to me this is a technology that seems to work quite well for wireless connections between mobile devices. The WR-7 has built-in Bluetooth Technology Version 4.1, and it worked flawlessly with all of my mobile devices as well as my shack’s PC.

For a full week, I used the WR-7 as the speaker for my shack computer, and it was most impressive. In fact, it makes for a nice compact external speaker to pair with my SDR applications. AM audio, piped through Bluetooth into the WR-7, is a treat.

For a few nights, I even streamed OTR productions of “Buck Rogers in the 25th Century” with my shack computer, connected to the WR-7 via Bluetooth. The WR-7 was actually in the adjoining room, yet the Bluetooth connection was strong and never dropped the audio. The resulting sound was nothing short of amazing: if you closed your eyes, it almost sounded like a valve set from 1939.

And that’s another thing about the WR-7 worth noting: It’s so small and so simple in design, it fits in anywhere, and isn’t in the least obtrusive, all while filling the room with its warm, rich sound.

Summary

Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget some of my initial impressions. Here is the list I formed over the time I’ve spent evaluating the WR-7.

Pros: 

  • Superb, room-filling, rich audio especially considering its very compact package
  • Very good FM sensitivity
  • Internal battery powers it for dozens of hours between charges
  • Easy to recharge via any 5VDC USB source
  • Easy Bluetooth connection and brilliant audio
  • Simple operation

Cons:

  • Volume and selection knobs could be slightly small for some users’ hands
  • Volume range more limited than most, upper volume capped
  • Although it does come with a nice lightweight carrying pouch for traveling, you might wish for a little extra protection in a suitcase or carry-on bag

Radios like the Sangean WR-7 give me hope that consumer electronics might be heading back in what is, in my humble opinion, the right direction: that is, toward quality.

The WR-7 is really a quality piece of kit: it has a solid feel (imparted by solid wood), has an acoustic chamber that produces excellent audio, and you can tell that the FM receiver wasn’t simply an “add-on” feature, as it works quite well.

While you won’t see many radios like this reviewed on the SWLing Post, I’m glad I agreed to take on this one.  It was an fun exercise, and reminded me why I love doing radio reviews: sometimes these digital marvels really surprise me. That, and I’m enough of a radio and consumer electronics geek to bask in the indulgence of pure listening!

Good one, Sangean! Accolades!

BBC is “keen to exploit DRM” but manufacturers must develop a multi-standard receiver chip

(Source: Radio World via Mike Hansgen)

LONDON — The BBC World Service, available on radio, TV and online, is part of one of the largest news organization in the world, the BBC.

The weekly reach of the World Service on all platforms accounted for 269 million (up from 246 million in 2015–16).

[…]Large numbers of the BBC’s audience still need international radio broadcasts.

[…]Right from its late ’90s inception, the development of Digital Radio Mondiale was fully supported and enhanced by the BBC World Service. DRM was seen as an efficient replacement for the analog AM transmissions. When we consider scarcity of spectrum for new uses and appreciate the characteristics of the radio broadcast bands, we recognize the tremendous properties these continue to offer broadcasters to deliver programs over sometimes very large distances and areas or in difficult terrain.

[…]The BBC is keen to exploit DRM in order to deliver, to key markets, BBC content free of gatekeepers in a form that can be accessed easily.

For that to be possible, the multi-standard receiver chip is required, and manufacturers must appreciate and act on this global market potential.

2018 ARRL Midwest Convention STEM TechFest: August 4 & 5, 2018

Many thanks to SWLing Post contributor, Dave Cripe (NM0S) for sharing the flyer above announcing the first annual Midwest STEM TechFest. This looks like an exciting event and frankly where I believe where most amateur radio conventions should be investing their time: in recruiting future engineers and makers! Well done!
