Nothing to hear on shortwave? Jacques disagrees…

Many thanks to SWLing Post reader, Jacques Catherine, who left the following comment on our post from 2012: Is there anything to listen to on shortwave?

“I live in Mauritius Island in the Indian Ocean and I’ve been listening to Shortwave since I was a kid (I’m 58 today) on my dad’s good old Phillips wooden valve radio.

I’m sorry, but shortwave is certainly not dead. After having read all the comments above, I come to the conclusion that reception definitely depends on your location.

The Tecsun PL-660.

I have two Tecsun receivers ( Tecsun S 2000 and PL 660) hooked to a Windom antenna and an ATU. I receive dozens of stations from all over the world here as well as a lot of stuff on ssb, including – in the morning – New York MWARA (8825.0 usb), Gander (8831.0 usb) or, in the evening, Brisbane (5634.0 usb).

Broadcast stations from Japan, Taiwan, India, Iran, Australia, Singapore, China, Africa and even the US, come in here loud and clear with very little static, depending on the season and time of the day. I think I’m privileged to be located where I am !

And I bought some years back a pair of cheap small wooden amplified speakers in Hong Kong that reproduce exactly the sound of my dad’s old valve radio!”

Thank you for your comment, Jacques. You’re right: it’s all about your location…and you certainly live in a prime spot!

I’m most fortunate that I live where I do–quite far away from sources of noise that plague our urban readers/listeners (and that have plagued me in the past). My location is not ideal (from a radio/receiving standpoint) because my ground conductivity is very poor and I’m in North America where very few broadcasts are targeted these days. I do, however, have the space for a rather large horizontal delta loop antenna that serves me well across the HF bands. I might have invested $50 in the antenna wire and components five years ago.

When propagation is good, some broadcast bands are actually packed tightly with signals. Indeed, Thursday last week, I could’ve easily logged two dozen stations on the 31 meter band alone. Here’s a screen capture from the spectrum display of my SDR:

If you live in an urban area and feel that you’re missing out on the action, consider taking your receiver outdoors and away from interference. Take your receiver on hikes, camping trips or to the beach. You might be surprised by the number of stations you’ll log!

Recently, our friend London Shortwave has been posting an amazing array of broadcast recordings he’s made in a park in the middle of London, England. He’s the guru of mitigating urban interference.

When I have time to curate the recordings, I hope to do a 2016 update of “Is there anything to listen to on shortwave?“–it’s been on my to-do list for a while now.

Jacques, thanks again for your comment and reminding us to keep listening!

A.P. Richards’ 1939 thesis on the Crosley WLW Model Super-Power Radio Receiver

In response to our recent post about the Crosley WLW Super-Power receiver, SWLing Post contributor, Larry Hagood, writes:

A photo of Dr Richards from the class of 1927.

I am an EE student at Oklahoma State (Formerly Oklahoma A&M)–the school where the designer of the WLW [Super Power receiver], Amyle Richards, got his BSEE in 1927.

[Richards] wrote and submitted a masters thesis on the design of this radio, which earned him a PhD!).

I found a picture of him in the Engineering South building and found him in the 1927 yearbook in the library.

Anyway, the archive department located his paper on the WLW and is scanning it for me.

Many thanks to Larry for doing the research and sharing a scanned copy of Dr. Richards’ thesis about this Crosley benchmark receiver!

Ken’s E. H. Scott Philharmonic Beam of Light console radio

In response to an inquiry in our post about the Crosley WLW Model Super-Power Radio Receiver, SWLing Post contributor, Ken Carr, writes:

I’m not sure if my radio is a ‘benchmark’ but it sure is close to it.
It is the E. H. Scott Philharmonic Beam of Light console radio.

Mine appears to have been built in 1939 or early 1940. It has 30 tubes, most of which are covered by chrome-plated shields. The power supply/amplifier (4 6L6’s in the output stage), receiver, 15″ speaker and cabinet easily weigh over 150 pounds.

It took me two years of occasional work (I am retired so I don’t rush) to get it going and working reasonably well. I had to replace over 100 capacitors and correct some B+ voltage problems left by a previous repair person.

None of the knobs are correct (mine came without them … 9 required) and replacements are difficult to come by (and quite expensive when they do appear).

When receiving a strong station the volume is such that it would easily drown out anything within 100 yards (and with no distortion).

Some day I will post some details and photos on my WordPress site (idlenot.com). I’ll be sure to let you know, Thomas. [Note: Yes, Ken, please do!]

Oh, the first time I powered it up and received a station they were playing Light My Fire (The Doors, I think). Appropriate. I put a video of it on YouTube. The radio is all apart as I was still working on it at the time.

Click here to view on YouTube.

Now that is serendipity, Ken–I mean, the first music you hear after restoring this beauty is Light My Fire? Brilliant!

The E. H. Scott Philharmonic Beam of Light is a benchmark console by any standard. I first learned about this radio through a local classified ad–the owner was selling the internal components (and original knobs) but had no cabinet. I believe he was asking $1200. The chrome plating is such eye candy, I can see why some owner in the past removed it from the cabinet to save space. Still, it was a shame the cabinet had been discarded–as one can see from your photos, the craftsmanship is simply stunning.

Ken, thank you for taking the time to share the Beam of Light console with us!

Aluminum foil: Larry’s simple AN200 antenna modification

12 Replies

Many thanks to SWLing Post reader, Larry Caracciolo, who comments:

I bought the AN-200 in the spring of 2015 off of eBay. I was favorably impressed with the product. Comparing it to my old 9′ diameter tuned/shielded loop from 1992, there are some similarities and differences.

The Hallicrafters SX-96 (Image: Universal Radio)

I live in an apartment complex so plenty of radiated electromagnetic noise is present. I use a modified [Hallicrafters] SX-96 (AVC ckt was modified for improved modulation acceptance). The AN-200 does null out local static sources, somewhat, but not well enough to dig out weak stations. The tuning range for the loop is just at the bottom of the AM band (about 535 khz) to just over 1700 kcs.

On a whim, I wrapped aluminum foil around the loop and grounded it to the SX-96 chassis – in wistful hope of achieving some shielding from the RF has. As soon as I connected the aluminum foil ground clip to the rx chassis, all RF noise ceased and signals appeared from the mud. However, the tuning range is attenuated above 1200 kcs.

My favorite frequency on the AM band is 590 kcs. During the night, as many as seven different stations rose from the noise and provided station IDs at just the right moment. My best catch here in Everett, WA is KCSJ, a 1KW station in Colorado Springs.

From time to time, stations on the low portion of the AM band are accompanied with echoes – what I took for two stations and a small time delay between the same broadcast was actually multi-path to the degree that nearly 1/2 second separated the arriving signals. Short-delayed echoes, anyone? I’ve not observed this on frequencies above 1000 kcs.

Other sources of RF noise can come from the laptop, the cable modem, and even CFBs in other rooms. For truly noise-free listening environment, I place the laptop in sleep mode and unplug the cable modem. I’m quite happy with the AN-200 loop. Affordable, easy to use, easy to tune.

Thanks so much for sharing your experience with the AN200 loop antenna, Larry!

As anyone who grew up in the era of TV rabbit ears knows, aluminum foil can simply work magic in a pinch! There is no easier material to work with either!

As I pointed out in previous posts, the AN200 loop antenna is quite affordable. I just did a quick price search:

The Tecsun equivalent of this antenna (the AN100) is available from various sellers on eBay from about $15 – $30 US.
The Kaito AN200 (Kaito’s branded version) is available on Amazon for $30 shipped.
With the purchase of the Eton-Grundig Traveler III, Eton-Grundig Field, or Eton-Grundig Satellit, Universal Radio will include a free AN200 with your purchase.

Many thanks to several SWLing Post readers who have shared this news from the Radio Belarus website.

Since I rely on a machine translation of the news page via Google Translate, I’m not totally clear about the details, but it appears Radio Belarus is shutting down their longwave, mediumwave and shortwave broadcasts on April 1, 2016.

Any SWLing Post readers out there who can read and translate the details on this page? If so, please comment and I’ll post the translation here! Thanks!

UPDATE: SWLing Post contributor, Igor, comments with the following translation which was also confirmed by Ed:

Due to the fact that National Government Broadcasting Company of Belarus Republic refused services of the Belarus Radio and TV Transmitting Center, since April, 01 transmission of radio programs of “1 National Channel of Belarus Radio” and “Radiostation Belarus” on LW, MW and SW bands will stop:

– by transmitting center in Kolodishci:
– “1 National Channel of Belarus Radio” on 7255 KHz, 250 KW
– “Radiostation Belarus” on 11930 KHz, 250 KW
– “Radiostation Belarus” on 11730 KHz, 150 KW
– “1 National Channel of Belarus Radio” on 6080 KHz, 150 KW
– by Osipovich transmitting center in Sosnovy:
– “1 National Channel of Belarus Radio” on 279 KHz, 500 KW
– “Radiostation Belarus” on 1170 KHz, 800 KW
