Alternative sites for Dayton Hamvention proposed

Dayton Hamvention logo_2

Yesterday, the Dayton Daily News published an article about the problems with the aging Hara Arena, home of the Dayton Hamvention.

Here’s an excerpt from the article:

Fears about Hamvention leaving town because of Hara Arena’s economic struggles has local officials scrambling to propose alternative sites for the economy-boosting event.

Hamvention, the world’s largest gathering of amateur radio enthusiasts, injects millions of dollars into the local economy each year. It has been held at Hara Arena since 1964.

But the arena has struggled financially, and an Iowa-based consultant firm recently asked the city of Trotwood to buy the venue, which Trotwood officials declined. The venue’s owner says the arena is on better financial footing today.

A series of emails obtained by this newspaper through public records requests show that local officials fear Hamvention could pack up and move out of the region and highlight their efforts to keep the event in the Dayton region.

The Dayton/Montgomery County Convention & Visitors Bureau has worked with city of Dayton staff on a Plan B to ensure the event remains in the county if it needs to relocate, said Jacquelyn Powell, the bureau’s president and CEO.

“I want to make it clear that this isn’t the first year that we’ve looked at Plan B options,” she said. “There have been other years where we’ve had this conversation as well.”

The Hamvention board has no intentions of leaving Hara Arena, said Jim Tiderman, general chairman of the Dayton Amateur Radio Association, which hosts the event.

“We do not have any plans whatsoever for relocating,” Tiderman said.

News of Hamvention’s possible relocation was mentioned in an email dated July 7 that was obtained by this newspaper through a public records request.

As mentioned in the article, the thought of the Hamvention leaving Hara is not a new one. The Arena leaves much to be desired cosmetically and even functionally–it’s an old venue that requires a sizable investment to maintain.

The Hamvention flea market is, without a doubt, my favorite part of the event.

The Hamvention flea market is, without a doubt, my favorite part of the event.

Earlier this year, I spoke to a long-time DARA representative who assured me that the club wants to keep the Hamvention at Hara for obvious reasons. He did admit, though, that they’ve always had a “Plan B” and even “Plan C” in place, should Hara close its doors.

He mentioned that, each year, Hamvention attendees urge DARA to find a new home, but the fact is Hara is not only the largest venue around, but is the only one on one level. With an aging ham radio population, accessibility becomes a higher priority every year. Those using scooters and wheelchairs would find it frustrating to compete for elevators and lifts in multi-level venues.

As the Dayton Daily News notes, one alternative would be to have two separate locations: one for the inside exhibits and one for the flea market. Selfishly, since I host an inside exhibit table, I appreciate the fact that the flea market is within easy walking distance. It would upset me if they decided to split the venues.

The fact is, no decision has been made yet. DARA still plans to host the 2016 Hamvention at Hara Arena and has no intention of moving anytime soon. That is, as long as the owners of Hara Arena can keep it afloat.

Universal Radio: new Whistler scanners and a “QRP corner” page

The Whistler WS1098 Scanner

The Whistler WS1098 Tabletop Scanner

I recently had a conversation with my good friend Fred Osterman, president of Universal Radio. Fred told me about a couple of items on their website I thought might interest Post readers:

  • A QRP Corner page with quick links to products and categories that are relevant to QRPers, portable operators and those interested in communications preparedness. The new QRP corner page can be found by clicking here. Fred notes that he page is a work in progress with regular additions.
  • Fred has also posted preliminary information about new Whistler Scanners: the Whistler WS1088 and WS1098. Fred is impressed with the preliminary product information and should have pricing and availability soon (both units are still pending FCC approval).

I’ve read through the specifications of the new Whistler scanners: I love the fact that they come with frequencies banks that can be loaded by simply entering your zip code (in the US). I find that programming scanners–as well as modern VHF/UHF handhelds–can lead to a serious headache. I’m happy to see that manufacturers like Whistler and Uniden are finally making the process much easier.

Many thanks for the update, Fred!

Many thanks to SWLing Post reader, Robert Gulley, who notes the following on his blog:

I found this interesting post from Scientific American concerning the lack of reliable wireless communication in aircraft in 1915 – just one of those fascinating historical tidbits.

You can read the full post on Robert’s website or Scientific American.

It is fascinating to see “old school” innovations that made long distance communications possible in 1915; before wireless technology became as practical and accessible as it was even only a decade later.

Adafruit Industries: an amazing resource for electronics experimenters

SWLing Post contributor, Richard Langley, writes:

In a recent blog posting, you mentioned the use of Arduinos in the radio hobby. Those of us who have experimented with Arduinos (and Raspberry Pis, etc.) likely have come across Adafruit Industries when looking for hardware bits and pieces to use in our maker activities.

There is a great article on Limor Fried and her company in the latest issue of the IEEE news magazine “The Institute” and it’s also available on line:

And there’s a short video up on the Web where Fried explains the company’s purpose and philosophy:

Richard then added:

[Here is a] cute Adafruit video introducing the concept of (radio) frequency to kids:

Very cool!  Thanks so much, Richard, for sharing this. Adafruit looks like not only a true community player, but a comprehensive source for the electronics experimenter! My daughters love the Adafruit video; now to dig up all of the previous episodes!

I’m planning to learn more about Arduinos and my RaspberryPi this winter, so I’ll keep Adafruit bookmarked!

Many thanks to SWLing Post reader, Stan (WA1LOU), who writes:

“Enjoy your blog. I have been reading it for years. [H]ere is something your readers might be interested in that I mentioned in my blog today:

http://www.horzepa.com/2015/09/computer-controlled-switch-system.html

Very cool! Goes to show that there are a countless number of applications for the Arduino system to be used with amateur and shortwave radio.

Craig Seager’s review of the Dansk RX4000 receiver

Dansk ReceiverMany thanks to SWLing Post reader, Rob Wagner, who writes:

Craig Seager is one of Australia’s finest SWL DXers, a longtime listener with great experience on shortwave, mediumwave and other modes. His amateur radio callsign is VK2HBT. Craig also has another special interest – old radio receivers. He has personally restored many fabulous radios to full working order and has accumulated a fine collection of his own. His knowledge of communications receivers is extensive.

The Mount Evelyn DX Report blog is delighted to welcome Craig who, over the next few months, will regularly contribute a new series called Retro Receiver Reviews – a look at some common and not so common communications receivers from the past. This series will be of interest to both amateur radio operators and shortwave listeners.

Craig’s first review has just been published, covering a radio not often seen these days – the Dansk RX4000 receiver. Check it out at:

http://medxr.blogspot.com.au/2015/09/retro-receiver-dansk-rx-4000.html

Thanks for passing this along, Rob!  That Dansk RX4000 sounds like a robust receiver, with a bullet-proof front end. A nice addition to any collection.
