Art Bell’s “Midnight In The Desert” to be broadcast on shortwave via WTWW and WBCQ

Many thanks to SWLing Post reader, Mike, who informs us that Art Bell is returning to the airwaves with a new radio show called Midnight in the Desert. Like Coast to Coast AM, (which Bell retired from several years ago) Midnight in the Desert will also focus on paranormal activity.

Mike also points out that Bell has also announced Midnight in the Desert will be broadcast on WTWW (5,085 kHz). WTWW will start airing the show July 20, 2015 from 9:00 pm – Midnight Pacific time.

Indeed, after looking at the list of radio stations rebroadcasting Midnight in the Desert, I noted that WBCQ, in Maine, will also carry the show on 7,490 and 9,330 kHz.

The Panasonic RF-2200: an early birthday gift

21 Replies

This week, I purchased a radio that I have lusted after for years: the Panasonic RF-2200.

I justified this eBay purchase because June is my birthday month and…well…do I need anymore justification!?! Just look at this beautiful analog dial:

In truth, I’ve been wanting a benchmark portable medium wave receiver for ages, and I believe there are few better than the venerable RF-2200.

I picked the RF-2200 this morning and I’ve only had it on the air a few minutes. It effortlessly picked up my local benchmark medium wave and FM stations. The audio fidelity is brilliant and the ‘2200 appears to have a very low noise floor. I haven’t had a moment to truly cruise the shortwave bands, but I plan to over the course of this week and shall report back.

James’ vintage transistor radio collection

In response to my recent post about the vintage Arvin 68R58 transistor radio, SWLing Post reader, James Patterson, has shared photos of his collection in New Zealand. James has captioned each photo below:

This portable Sanyo was bought at a “Second Hand” shop. It had badly corroded battery connections. I repaired it and it works fine now.

Very early National portable with twin speakers, broadcast [band] and [shortwave. Works very well.

This PYE Caddy was actually made here in New Zealand. I believe the design was from the UK though. It still works very well.

The PYE Caddy without the plastic cover.

Very popular in their day, the RED National Panasonic pocket AM Transistor 6. Works well.

Very early AIWA pocket Transistor 6. Still works well.

The “Murphy 8” Transistor radio. Broadcast band only. Wooden case in fab condition. Works very well.

This is the rear view of the “Murphy Transistor 8.” I gave it a new battery holder.

This is a “Murphy Transistor 7+” Im not sure what the “+” means because it does have only 7 transistors. Very good performer for its age. Wooden case is identical to the previous Murphy 8.

This is the rear view of the “Murphy Transistor 7 plus.” All very original, and works fine.

This National Panasonic DR 28 is not part of my early AM Transistor radio collection. It is, however, part of my shortwave radio collection.

Many thanks, James, for sharing photos from your collection! You certainly have some gems in there. I was not at all familiar with the New Zealand-made PYE Caddy, in fact. I’m curious if other radios were made in New Zealand in the past.

I bet you and I might agree that the Panasonic DR-28 (a.k.a. RF-2800 in North America) hardly feels “vintage,” but at 37 years old it certainly qualifies by most standards–hard to believe. The RF-2800 pops up on eBay quite often and has certainly held its value well. (Click here to search.)

Seeing the DR-28/RF-2800, in fact, is making me lust even more after the venerable Panasonic RF-2200! Alas…so many radios!

Hamvention find: the Arvin 68R58 AM transistor radio

8 Replies

Though I believe I spent more money at the Dayton Hamvention this year than I have in all previous years, I only purchased one radio: the Arvin 68R58 eight-transistor.

I spent a whopping $5 on the little Arvin in the Hamvention fleamarket. To be fair, the seller sold it for this modest price because he was not sure if the radio worked. But when I unsnapped the back leather cover, peered inside, and found the works remarkably clean, I suspected it might…

No original power supply was included, of course, and I was a bit concerned when I saw the somewhat out-of-character plastic battery holder. In the filtered fleamarket light, it appeared to me as if it required proprietary batteries–the holder appeared too small for C cells, and too large for AAs. There was no indication of the type of batteries it used, but since the spec read “6 volts,” I knew I could build a small AA battery holder, if need be.

So, at $5 (I bargained him down from $10, based on the doubt of operation) it was a very low risk purchase, and a potentially a fun project.

Back at home, I popped open the battery holder and looked inside…And I discovered the Arvin did, indeed, take four C cells. Simple enough! After inserting fresh batteries, I turned on the radio via the tone pot, and instantly heard beautiful, rich audio.

What I thought would be a project radio ended up being fully functional, and was, moreover, in tip-top shape.

So far, I’ve been very impressed with the Arvin’s AM sensitivity and audio fidelity. No doubt the generous ferrite rod antenna is doing the trick on medium wave.

Last night, as I tuned through the AM broadcast band, I was able to null out unwanted stations and noise amazingly well. There is something to be said of transistor radios from this era–let’s just say, they’re classics.

The Arvin has a simple set of controls: tone, tuning, and volume. There are no filter selections, of course, but I can tell that it’s quite wide; perhaps 8 or 9 kHz.

All in all, I’m very pleased with my little purchase, and the Arvin has become my new (vintage) bedside radio. Last night, I tuned in one of my favorite AM stations on 740 kHz, CFZM in Toronto, Canada. CFZM (a.k.a. “Zoomer Radio”) is not only a benchmark, but a right of passage for any worthy AM radio in my household. The Arvin passed the Zoomer test with colors flying.

And, yes, it even soothed me to sleep.

Now I only need to properly clean and restore the Arvin’s leather chassis and perhaps build a 6V-regulated linear power supply.

Next time you pass by a 1960s/70s vintage transistor, grab it! I’m certainly happy I did.

Now, I think I’ll turn on the Arvin, sip some dark beans, and put up my feet in the Pawley’s Island hammock…Cheers! Summer’s on the way.

Honoring Memorial Day: The White Cliffs of Dover

Dame Vera Lynn

Today is Memorial Day, and I’m feeling humbly grateful to all of those who paid the ultimate sacrifice for their country. Since I’ve been reading a lot of WWII history lately, I’ve also been playing a lot of WWII-era music here in my sanctuary to all things radio.

Few songs sum up the yearning sentiment of World War II better than Vera Lynn’s 1942 rendition of “The White Cliffs of Dover.” It’s an iconic song, one that helped British soldiers see beyond the war while mourning its painful toll. It was written in 1941 when England was taking heavy casualties, just before American allies joined the effort.

This morning, seeking something with a little authenticity, I played “The White Cliffs of Dover” though my SStran AM transmitter, and listened to it through “Scottie,” my WWII-era Scott Marine radio (above). I made this recording by placing my Zoom H2N recorder directly in front of the Scott’s built-in monitor speaker.

So here you go: a little radio tribute to all of those who fell–on both sides–of that infamous second world war.

And thanks to all who serve and have served in the name of “peace ever after.”

Immediately after packing up our table at the Dayton Hamvention, my buddies Eric (WD8RIF), Miles (KD8KNC), and I made the 30 minute journey to Bethany, Ohio, to visit the VOA Bethany museum.

Main entrance and front lobby (above).

Entering the transmitter control room.

Eric pointed out an article on the future of shortwave radio I published last year that the museum has posted in the hallway next to the control room (above). What an honor!

The satellite dish (above) was once used for VOA’s downlink/feed–now the West Chester Amateur Radio Association (WC8VOA) uses the dish for EME (Earth Moon Earth) contacts.

Back inside, WC8VOA has four full amateur radio operating locations stocked with Icom, Yaesu and Kenwood gear. The club president told us that an antique amateur radio station will soon be added.

Our docent took us on a tour of two vaults filled with vintage radio equipment and then a museum devoted to the legacy of WLW. The item in the photo above is a corona ball from one of the original towers–notice the holes from lightning strikes.

Example of an early radio kit (above).

A rare Third Reich radio (above).

When Ohio-based R.L. Drake Company stopped manufacturing amateur radio equipment, samples of their full product line were donated to the museum.

The Museum is planning substantial renovations to restore the VOA Bethany Station and become a first class institution. During the restoration, the Museum is only open one day per month to the public: The third Saturday of each month from 1:00 PM – 4:00.

When WLW was the one and only “Super Station”

For a Brief Time in the 1930s, Radio Station WLW in Ohio Became America’s One and Only “Super Station”

by Katy June-Friesen

When President Franklin Roosevelt, sitting in the White House, pushed a ceremonial button on his desk in May 1934, a five hundred thousand-watt (500 kW) behemoth stirred in a field outside Cincinnati. Rows of five-foot glass tubes warmed. Water flowed around them at more than six hundred gallons per minute. Dozens of engineers lit filaments and flipped switches, and, within the hour, enough power to supply a town of one hundred thousand coursed through an 831-foot tower.

Thus began WLW’s five-year, twenty-four-hour-a-day experiment: a radio station that used more power and transmitted more miles than any station in the United States had or would. The so-called super station—licensed by the new Federal Communications Commission (FCC) on a temporary basis—amped up the debate among broadcasters, government regulators, and listeners about how radio should be delivered to serve the “public interest,” a mandate laid out in the Radio Act of 1927, and influenced legal, programming, and technical decisions that shape the broadcast system we know today.

Since radio’s beginnings in the early 1920s, industry and government leaders promoted it as the great homogenizer, a cultural uplift project that could, among other things, help modernize and acculturate rural areas. The challenge was how to reach these areas, many of which received few or no radio signals in the mid-1930s. One solution was high-powered, clear-channel stations that could blanket large swaths of the country with a strong signal. These stations operated on “cleared” frequencies that the government assigned to only one station to prevent interference.

WLW had operated on one of forty designated clear channels since 1928. The station’s creator and owner, an entrepreneur, inventor, and manufacturer named Powel Crosley Jr. frequently increased the station’s wattage as technology and regulation allowed. In 1934, when WLW increased its power from 50 kW to 500 kW, all other clear-channel stations were operating at 50 kW or less. Now, WLW had the ability to reach most of the country, especially at night, when AM radio waves interact differently with the earth’s ionosphere and become “skywaves.” People living near the transmitter site often got better reception than they wanted; some lights would not turn off until WLW engineers helped rewire houses. Gutters rattled loose from buildings. A neon hotel sign near the transmitter never went dark. Farmers reported hearing WLW through their barbed-wire fences.
