Build a cardboard stand for the Elecraft KX3

Many thanks to SWLing Post reader, Tomasz Pabich (SP7Q), who has created the following Instructable describing how to build a cardboard stand for the Elecraft KX3.

Click here to view on Instructables.

I love how practical and affordable this project is. The stand would be simple to disassemble and take to the field in a go-bag or backpack. If it were ever damaged or lost, you could simply build another.

Of course, it would be quite easy to build similar stands for shortwave portables.

Thanks again for sharing your project, Tomasz!

Sangean DT-160CL: The correctional version of the DT-160

7 Replies

After publishing a post referencing the new Sangean DT-160 AM/FM radio, a number of readers noticed that Sangean has also produced a clear-cased version of the DT-160: model number DT-160CL.

This version, no doubt, was designed for sale in prison commissaries and is probably seen as a replacement for the venerable Sony SRF-39FP (which has been discontinued). The SRF-39FP is widely regarded as a superb mediumwave (AM) DXing ultralight.

In reference to the Sangean DT-160CL, SWLing Post contributor, Dan Hawkins recently commented:

Which begs the question: is this prison-quality radio really that good? I ask the question only because a good AM-FM prison radio must perform exceptionally well behind formidable prison walls. After all, nearly one percent of the US population is currently behind bars (down slightly from 2008) which is a substantial pocket radio market. Prison radios are typical sold in prison commissaries and prisons are big business nowadays. How does this radio compare to the famous Sony SRF-39FP? Inquiring minds want to know. Sangean is legendary for build quality. Does it beat the Sony?

After reading Dan’s comment, I couldn’t help but order the DT-160CL from Amazon.

The Sony SRF-39FP

I, too, am very curious how it will compare with the SRF-39FP in terms of battery longevity, audio fidelity, and overall performance.

I suspect the SRF-39FP will remain dominant on the AM broadcast band and possibly have better battery life (keep in mind, the SRF-39FP only uses one AA battery–the DT-160CL requires two).

As soon as I receive the DT-160CL (Amazon notes delivery will be Wednesday, August 3), I’ll pop fresh batteries in the DT-160CL and the Sony SRF-39FP, set them to the same volume level and frequency, then allow them to run continuously until the batteries are depleted. Of course, I’ll use the opportunity to compare performance on both AM and FM.

I’ll post comparison updates with the tag: Sangean DT-160CL v Sony SRF-39FP.

Ron’s mini review of the Sangean DT-160 AM/FM radio

10 Replies

Many thanks to SWLing Post contributor, Ron, who shares his impressions of the new Sangean DT-160:

The DT-160 just came in and here are a few impressions:

1.) The heft and feel of this set is superb…it has that solid feel the earlier DT-200X doesn’t. It is markedly smaller,too and the buttons have a firm solid feel the earlier models lack (finally!).

2.) Jay’s review is spot-on as usual…but the AM section is not what you find in a Sony SRF-59 or SRF-37W digital. Expect to get locals and semi-locals fine but it’s not going to be a DX machine on AM as the Sony’s are.

This is doubtless due to the need for a smaller ferrite bar; a Q-Stick or loop will fix that.

3.) On the other hand as Jay said it leaves the Sonys in the dust on FM, which is superb.

4.) Audio is very good as is ease of operation.

5.) The closest comparison is probably the CC Pocket; they doubtless use the same/similar Silicon Labs IC.

~~But unlike the CC no birdies were heard on AM~~. [Update: Ron has since discovered a few birdies on AM, like the CC Pocket.]

Is it worthwhile?

Yes, if only for the promised 100 hour battery life. No other similar receiver will run nearly as long.

[Thomas,] you may wish to order two; one for Dad,and one for you.

I will definitely buy the DT-160 for my father. I wonder if it’s packaged in a way that I could take it out, play with it, then re-package it as a gift? 🙂 Would that be wrong? Of course not! 🙂

I noticed that Universal Radio now also stocks the DT-160 and retails for $49.95 plus shipping.

Amazon’s price (today–they do fluctuate) is $39.99 with free shipping.

Vintage Unboxing: New-in-the-Box Magnavox D2935 Receiver from 1987

16 Replies

Sometimes good fortune drops in our lap at the least expected moment, but we have to act quickly to take advantage of it! This was the case with the receiver above; I spotted it on Ebay just moments after the seller posted a Buy-It-Now auction. Had I been planning to buy a D2935? No, but I immediately knew I was looking at something special.

This particular D2935 receiver from Magnavox had remained new and unused from 1987 until July 2016, when I had the good fortune of spotting the newly-listed Ebay auction and purchasing the radio for $175. Continue reading →

David enjoys hammock mobile SWLing with his Icom IC-92AD

Many thanks to SWLing Post contributor, David Korchin (K2WNW), for sharing this short video demonstrating the shortwave receive capabilities of the Icom IC-92AD handheld transceiver:

Click here to view on YouTube.

Frankly, I’m quite amazed at the clarity and fidelity of the Voice of Turkey interval signal on this handheld. Goes to show that with a proper antenna, and decent conditions, wide-band handhelds can certainly be used for shortwave radio listening! It also helps that David is outdoors, away from RFI, and was located on the coast of Long Island, NY.

Post readers: Have you had good fortune SWLing with wide-band handled transceivers? Please comment!

Sangean ATS-909X on eBay

Sangean ATS-909x on eBay

For those who might be interested there is a black version of the 909X on eBay with an auction end day of Monday early afternoon. The condition looks good from the pics (of course buyer beware!) and current bid is $127.50 with two bidders. I have one of the white series which bought several years ago from another ham right at this price, so needless to say I was happy (and lucky!)

Ron’s Bluetooth solution for robust shortwave radio audio

9 Replies

Many thanks to SWLing Post reader, Ron Wagner, who writes:

Thanks very much for your informative SWL pages. With the, seemingly, shortsighted, contracting world of SW broadcasters, you keep our interest alive!

Recently, you called attention to Jay Allen’s modification and installment of a new speaker for the Satellit 800. Not quite ready to open up my 800, even with a scratchy volume pot, I setout to find another way, not only for the 800, but for all of those older radios that “SWLers” love.

Walla, a Bluetooth TX/RX device (by JETech Designs) which connects to the headphone or external speaker jack of the radios. Then, with a Bluetooth speaker, put the TX/RX device on TX and pair with the speaker, and your off to an audio improvement in all of your radios.

Attached, see the TX/RX with my 800, G3 and ICF 7600 and my outdoor Bluetooth speaker. With today’s Bluetooth speakers, you can spend to suit your budget and ears. Now, I’m on my way to find Bluetooth headphones to pair with the Bluetooth transmitter.

What a simple and relatively affordable idea, Ron. I had been considering the purchase of a Bluetooth receiver for the AUX in port in my minivan’s audio system. If I understand correctly, this one unit can both send and receive Bluetooth audio. Very cool!

I could also imagine someone placing their shortwave portable outside–on a patio or deck–away from indoor radio interference, and using the Bluetooth link to port audio to a speaker inside the house. You wouldn’t have tuning control (and you’d have to remember to bring the radio inside if rain is in the forecast–!), but you would have audio control.

Looks like this JETech receiver/transmitter is available on Amazon or directly from JETech. Thanks again for the tip, Ron!
