Photo emerges of Droitwich mast and LF antenna

Many thanks to SWLing Post contributor, Dave Porter, who writes:

This picture [above] has just emerged, photographer unknown but most likely a rigger from the top of one of the 700′ masts there!

This was taken at Droitwich sometime after colour photography came in (late 1960’s) and before 1986 when the four wire Tee was replaced by a new design developed by BBC Antenna Engineer Tony Preedy, G3LNP that improved upon the 11-j85 Ohms driving point impedance giving a few more ohms and less capacitive reactance for the 2 x 250kW B6042 transmitters and a greater radiation efficiency.

Tony’s present LF array does not look so symmetrical as it comprises four separate Tee wires with the drops as a square box rather than the centre-joined drops of this one.

Tony also developed a low profile Tee antenna over 3 x 17m wooden telegraph poles for MF at up to 1 kW that was used when planning restrictions were enforced. Efficiencies were up to 40% at the 1500 kHz end of the band. However, if used by birds as an overnight roost it could provoke VSWR trips on solid state transmitters, the fix was to use a sliding reduced power detector that wound down the power to a level that did not trip the VSWR monitoring. Old tube transmitters were not affected!

The operating frequency for this LF Tee was 200 kHz at that time, now the antenna is on 198 kHz

Wow–thank you, Dave, for sharing this photo. We truly appreciate your impressive knowledge of UK broadcasting and history! And, wow! The views those riggers took in!

Massive photo galleries of the Dayton Hamvention

This is the first year I’ve missed the Dayton Hamvention since 2009. As I mentioned in a previous post–besides hanging with my friends–I really enjoy browsing the flea market and inside exhibits looking for deals and cool innovations.

In 2016, I took loads of photos of both the Hamvention Flea Market and Inside Exhibits. I did this partly thinking it would be our last year holding the Hamvention at Hara Arena (turns out, I was absolutely correct).  Post readers asked that in 2017, I take photos of the new venue at the Greene County Fairgrounds in Xenia, OH, so I did.

I enjoy taking and sharing these photos so much, I’ve continued to collect hundreds of photos every year since to help document how the largest ham radio gathering event changes over time.

In the flea market, I try to include price tags when possible to give our international readers an idea of how much vintage gear costs.

If you’d like to take a trip down memory lane with me, check out the linked photo galleries below:

Help Paul identify this antique radio device

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

I hope you’re well. Thanks for all you do with SWLing Post etc. I’m so grateful to you for the consistency with which you update that site. Almost every day there’s something of interest to me.

I wanted to see if this might be something you and your wonderful army of readers could help with?

There’s this family photograph of my granddad (see above). It would have been taken in London in about the late 1920s or early 1930s, and it looks kind of like it’s posed or in a studio. But they seem to be listening to a radio device, and I wondered if anyone out there might be able to identify it? Perhaps there’s a whole genre of studio photographs of the era which showcased new technology? Or maybe not…? Any ideas would be so welcome!

Kind regards,
Paul

A photo tour of the 2019 Shelby Hamfest

My Labor Day weekend was free of travel this year, so I was able to make another pilgrimage to the Shelby (North Carolina) hamfest with my good buddy, Vlado (N3CZ).

The Shelby Hamfest–referred to, locally, as “The Grand-Daddy of them All”–has long been regarded as one of the largest outdoor hamfests in the southeast US. This is the fourth year I’ve made a concerted effort to publish a photo tour of the event.

Weather was ideal for the hamfest–clear skies, sunshine and a dry weekend. No doubt, this was one of the reasons I believe the hamfest was well attended.

2019 Huntsville Hamfest photos: Vendors, Clubs and Organizations

As promised by Huntsville Hamfest veterans, Sunday was a more relaxed day at the Huntsville Hamfest than Saturday (which was insanely busy–in a good way).

Since we had a table in the vendor section of the hamfest, I started taking many of the photos below before the doors officially opened. As you’ll see, all of the major radio manufacturers and retailers were present in Huntsville. It’s no surprise, as it turns out Huntsville is the third largest hamfest in North America (Orlando Hamcation is #2 and Hamvention #1).

[Note that Huntsville flea market photos were posted yesterday.]

2019 Huntsville Hamfest photos: Flea Market

Yesterday (Saturday, August 17), was the first day of the Huntsville Hamfest in Alabama.

Over the years, I’ve heard from a number of friends that Huntsville is a must-see hamfest. And, boy, were they right! Turns out the Huntsville Hamfest is one of the largest hamfests in North America.

The entire event is held in the amazing Von Braun Center and is fully air conditioned–a good thing as temperatures were pushing 100F/37.8C yesterday!

I took a number of. photos in the flea market area of the hamfest. In truth, though, this is only a small sampling of what was there. I told a friend that–in terms of selection and radio density–this was one of the best hamfest flea markets I’ve ever seen. If you were looking for ways to rid yourself of your hard-earned cash, this was the place to do it!

Click on the photos in the gallery below to enlarge each image. Note that I plan to take photos of the vendor/club areas today and hopefully post them tomorrow:
