The Tecsun S-8800: A new receiver in the works

SWLing Post contributor, OWL, writes:

It seems that Tecsun has a new large portable in line.

Someone posted a photo of a new Tecsun product catalogue which shows a new model S8800.

The Tecsun BCL-3000 for comparison.

Apparently it uses the housing of BCL3000 [see above] and is multiple conversion (so a PL880 inside?), DSP based with separate LSB/USB and 10Hz minimum tuning step, and comes with a remote control (for direct frequency input?). Two 18650 batteries are used.

Many thanks for sharing this find, OWL! This is a very curious development from Tecsun.

I can imagine why Tecsun is re-using the BCL-3000 (a.k.a. Grundig S350DL) body–not only is it roomy inside, but it’s proven to be a popular large portable form factor over the years. Of course, since this is an existing chassis design, design/development costs will be minimal. If Tecsun is including a remote, I’m sure OWL is correct: it’ll aid with direct frequency entry. The S-8800 will be the first portable shortwave radio with remote control I’ve seen in many years.

If audio is anything like its predecessors, I would expect rich fidelity from the built-in speaker. In terms of performance, though? This is a completely different receiver than the single-conversion BCL-3000, so only time will tell.

Not all Degen DE1103 eBay listings are the new DSP vesion

I’ve been interested by news of the updated DSP version of the Degen DE1103.

I just saw an eBay auction for a used DE1103 which listed “DSP” in the title. But I looked at a photo of the product and it showed the labeling of the original product. If you look at the bottom left of the unit, the older radios have two lines of product description printed in black, and the newer radios have one line.

Based on photos I found online, here is the old product’s description (which applies to both the Degen and Kaito versions)

“PLL FM STEREO/SW MW LW DUAL CONVERSION SYNTHESIZED WORLD RECEIVER”

And here is the new product’s description.

“FM STEREO/SW MW LW DIGITAL WORLD RECEIVER”

I thought this would be useful for anyone wishing to buy the new DSP version of this radio where a photo of the actual unit is shown.

Eric has a good point–many times on eBay, sellers simply copy descriptions from previous or existing listings. You my find a used DE1103 listed as a unit with DSP. It’s best to confirm the version with the seller before purchasing. To my knowledge, only the 2015 version of the Degen DE1103 has DSP.

It doesn’t matter that propagation is rather poor this morning: I have a Sony ICF-SW100, a good cup of coffee, a beautiful sunrise and Radio Australia is loud and clear on 9,580 kHz.

All is well.

Many thanks to SWLing Post contributor, Richard Langley for the following guest post:

AFVN: The GI’s Companion — A Tribute To Our Vietnam Veterans

Radio station WEBY on 1330 kHz in Milton, Florida (near Pensacola and Elgin Air Force Base), has produced a 10-hour documentary on the American Forces Vietnam Network. This documentary aired in two-hour segments in the afternoons of 26 through 30 October 2015. But it is being repeated in its entirety between 8:00 a.m. and 6:00 p.m. CST (14:00 to 24:00 UTC) on Veterans Day (known as Remembrance Day in Canada and elsewhere), 11 November.

The WEBY website is http://www.1330weby.com/ and a backgrounder on the documentary can be found here: http://www.1330weby.com/images/afvn/AFVN_Documentary_on_WEBY.pdf and a timeline of U.S. broadcasting in South Vietnam here:
https://www.afvnvets.net/hist—timeline.html

WEBY runs 25 kW during daytime hours (and a puny 79 watts at night) and can be heard in parts of four states (Florida, Alabama, Mississippi, and Louisiana) but it also streams its programs on the Internet and so can be heard around the world. I’ll try to record some of the streamed audio in case the documentary is not available after the broadcast.

I was alerted to this documentary by a recent episode of PCJ Radio International’s Media Network Plus (24 October) during which Keith Perron interviewed the producer. That interview is worth listening to, too.

AFVN transmitted on AM and FM throughout South Vietnam. I never had the opportunity to listen to AFVN personally, but as a high school student, I did use to listen to the Armed Forces Radio and Television Service (AFRTS) on shortwave from time to time. AFVN received some of their broadcast material via AFRTS broadcasts from Voice of America transmitters in Delano, California, and the Philippines. A scan of a QSL card I received for a broadcast from AFRTS Los Angeles via Delano in April 1964 [see below].

Shortwave Radio Recording: “The Buzzer” on 6,998 kHz

Screen capture of the Web SDR waterfall tuned to 6,998 kHz.

On Friday, Andrea Borgnino, tweeted that he could once again hear “The Buzzer” on 6,998 kHz. Of course, during the day, I couldn’t hear the signal from my home in North America.

I could, however, easily hear the signal via the University Twente Web SDR in the Netherlands.

Here’s my recording:

As I’ve mentioned before, I’m pretty sure this is simply a pirate having a little fun relaying UVB-76 audio on 6,998 kHz.

Tudor confirms: a new version of the Degen DE1103

After publishing our previous post about a potentially redesigned Degen DE1103 with DSP, SWLing Post reader, Tudor, comments:

Yes, the DE1103 looks like it’s been redesigned. You can see it dissected here:

And, if I’m not mistaken, the SiLabs DSP chip can be seen in this picture:

Wow–thanks so much for confirming this, Tudor! This is obviously a redesigned Degen DE1103. I also noticed “NEW-DE1103-MAIN-1.2” silk-screened on the board:

The Hong Kong-based eBay vendor Bigbargainonline is selling the new Degen DE1103 for $79.00 US shipped. I’ve purchased from them several times before and was pleased with the experience.

There are other vendors selling the new Degen DE1103 as well (click here to search eBay) but make sure you’re purchasing the 2015 version of the Degen DE1103 since you can still find the cosmetically-identical legacy DE1103 new in box.

Tudor, thanks again for sharing a link to the discussion on tecsun.com.cn–while I can’t read Chinese (and the Google translation leaves something to be desired!) the photos certainly tell the story.
