The New Degen DE1103 DSP: First impressions & review

IMG_20151124_085005760_HDR

When I discovered that Degen had recently refreshed the receiver design of the DE1103, I was intrigued, to say the least. The original DE1103 sported some serious performance for a sub-$100 receiver.

The 2015 model of the Degen DE1103 implements a DSP chip (the Silicon Labs Si4735-D60).

Yet I was on the fence about purchasing the new DE1103. Why? In truth, I never fell in love with the original DE1103. While I appreciated the 1103’s unique analog-style digital display, I never got used to its quirky ergonomics. Degen had quality control issues, too: I had to return two faulty units before getting one that worked as advertised (incidentally, I had a similar problem with the Kaito KA1102).

Then last week, SWLing Post reader, Ron, contacted me. He had purchased the new DE1103 from Hong Kong-based eBay vendor Bigbargainonline.

Ron kindly provided the SWLing Post with his impressions of the DE1103, as follows:

Performance is roughly on a par with the earlier dual conversion version. This one is just as hot, but no hotter.

If you were thinking a GP5 on a bigger ferrite bar, yes…and no.

There is one major gripe…[this unit] will not remember frequencies set with the BFO on, like the earlier dual-conversion version did. Instead you have to turn the BFO on for each memory frequency [for which you] need it.

One thing [I] noticed right off was the almost complete lack of AGC “pumping” on CW and SSB that all earlier versions had (yay!) but this plus comes at the cost of having the BFO “remembered” in memory.

Zero-beating (or centering) the BFO to null on WWV and local AM stations to check alignment was…strange. At null beat the BFO seems to quit for a second. It is fine
either side of zero beat, however.

This is doubtless due to Tecsun’s adapting the Silicon Labs IC to a full range BFO like this. Recall the same IC in the GP5 features Upper and Lower selection on CW/SSB.

This 1103 DSP version also has the GP5’s slight tuning mute, not a problem.

But for ease of operation in CW/SSB mode, the GP5 is [much] better IMO.

Ron also notes that he wasn’t pleased with the DE1103’s longwave performance and didn’t feel the mediumwave and shortwave reception was an improvement on the original DE1103.

He decided that he would sell this DE1103 and gave me first dibs, so I bit the bullet. I was eager to compare the new DE1103 with some of the other DSP-based portables in my collection. Ron dispatched the DE1103 immediately–it arrived a few days ago, but I didn’t have a chance to test it until yesterday.

I took the Degen DE1103 outside, sat it on the tailgate of my truck and put it on the air…

I tuned around the mediumwave band and picked up all of the local benchmark stations. Same with FM. So far, this tuning confirmed Ron’s assessment of the DE1103: it didn’t surpass the original.

But the shortwave bands were a different story.

As I tuned around the HF bands, the DE1103 seemed to receive quite a lot signals.  But in most instances, I could hear local AM broadcasters bleeding in, as well. Indeed, imaging was prevalent across the shortwave bands–the receiver was obviously being overwhelmed by a local broadcaster.  Unfortunate.

Could strong interference account for this? While there are local AM broadcasters around, they’re not exactly “blow-torch” stations. Indeed, I’ve never had overloading issues with other shortwave portables I’ve used in the same location–not even with my Kaito WRX911!

Imaging was prevalent on the DE1103 when it was tuned to pretty much any audible shortwave broadcaster.

Here’s a video of the Degen DE1103 tuned to the Voice of Greece on 9,420 kHz:

What you’re hearing in the audio is a local broadcaster bleeding in. Note that when I tune off-frequency, no imaging is heard.

Wondering if something had changed locally–and just to be fair–I pulled out my Sony ICF-SW100 and sat it next to the DE1103. The Sony had no issues.

This time, I tuned to WWV on the 19 meter band and compared the two receivers:

As Dan Robinson expresses it, the ICF-SW100 “wipes the floor” with the DE1103. There’s no hint of overloading in the SW100.

My buddy, Ron, is clearly a keen radio reviewer; obviously he didn’t hear overloading on the shortwave bands where he tested the rig, else he would certainly have mentioned it. The location where I tested the DE1103 does have some local broadcasters in the area, but no clear channel or high-power stations; in short, there’s no likely interference within a ten-mile radius to account for this debilitating performance problem.

Too bad…!

Obviously, the new DSP version of the Degen DE1103 is especially prone to imaging on the shortwave bands. In fact, it’s the only receiver I’ve ever tested that has overloading issues at this testing location (where I tested the original Degen DE1103, by the way).

My assessment? Avoid the new Degen DE1103.

A much better receiver with SSB for roughly the same price would be the venerable Tecsun PL-600 ($89.99 at Amazon and $89.95 at Universal Radio). If SSB reception isn’t necessary, you might also consider the CC Skywave or the very affordable Tecsun PL-310ET.

Dan compares the Sangean ATS-909X with two classic portables

Sangean-ATS-909X-Sony-SW07-Panasonic-RF-B65

Many thanks to SWLing Post contributor, Dan Robinson, who shares a radio comparison he initially posted in the excellent Extreme Shortwave Listening Facebook group. Dan writes:

When the Sangean ATS-909X was first released a few years ago, I decided that I would hold off obtaining one to let whatever bugs there might be in production get worked out.

I have always been impressed by the design of the 909X, but was cautious when it came to the question of overall sensitivity. I once owned the 909, had it modified by Radio Labs, but that seemed not to do much — the 909, in my view, suffered too much from the well-known deafness issue when using the whip antenna.

Over the years, I used and still own many of the classic portables. This includes the SONY 7600GR, Grundig SAT 500/700, 2010, E-1, SONY SW100/SW07, SONY SW-55, and the radio I consider to be at or near the top of the small portable heap, the Pan RF-B65. But a couple of weeks ago, I broke down and bid for a new in box Sangean 909X. It’s the black version, and arrived a couple of days ago.

I remain impressed by the 909X’s design — beautiful radio, wonderful large LCD and backlight, excellent filtering, along with a feature we used to see in the SONY’s — adjustable/variable attenuation. But I wondered how the 909X would stack up against two of my favorites, the SW-07 and RF-B65. I was crossing my fingers — but alas, initial results are not encouraging.

While the radio initially on its own seems to be quite sensitive, I lined it up next to the SW-07 and RF-B65 and did a comparison. Now, first I must note that propagation continues to be in the dumpster and I conducted this test in late afternoon.

All three receivers were tuned to Cuba on 11,760 khz — they were located next to one another on a table in the top level of my home here in Maryland. The results are seen in the video below.

You can hear how much more clearly the SW-07 and especially the RF-B65 handle a signal. With the Panasonic, stations just pop. Same with the SW-07.

Disappointingly, as you can hear, stations on the 909X appear to be buried in noise. It’s quite extraordinary — I was very surprised by this comparison and intend to perform additional side-by-side tests in different areas of my home, which does suffer from high noise levels likely produced by electric lines and a transformer outside (which is why a run a Wellbrook on my main radio stack downstairs). But it is notable that the 909X appears to struggle so, while the old classic portables SW-07 and B65 excel. Interested in the views of others . . .

Dan, this is very similar to my experience with the Sangean ATS-909X.

Like you, I absolutely love the design of the 909X–the large display, tuning wheel, front-facing speaker, ergonomics–but was pretty disappointed when I pitted it against three other (less expensive) portables on the shortwave bands.

I know the 909X performs much better when connected to an external antenna. I’ve also learned that fresh batteries are a must as the 909X’s sensitivity is directly related to supplying optimal voltage. I know, though, that you had fresh batteries in your 909X, Dan.

Again, many thanks for sharing your comparison.

William’s review of the C.Crane CC Skywave

CCrane-CC-Skywave

Regarding the C.Crane CC Skywave, SWLing Post reader, William Pietschman (W8LV) comments:

I find that the Skywave is so stable on the air band, I can use it to decode ACARS with the Android App!

Listened to WBCQ, and Arnie Coro’s show last night from Havana along with some Jazz music.

It pulled FM stations out of the air like nothing else, meaning the weaker ones here in my rural Ohio location. And I could pick up three NOAA broadcasts, two very strong, one scratchy…. Since the NOAA system is of course designed to let you pick up one station in whatever particular area of the county you live in, I consider this excellent!

With the AM I pulled in Canadians, Boston , stations in IOWA and KFI. I also note it’s very directional on AM… I could null out WTVN and pick up Texas with no problem. I have owned and do own lots of shortwave radios, and I MUST say, this is one hell of a good set!

It’s going into my Winter zip-up jacket pocket so it will always be handy for the DX Season, and I also notice that the headphones are VERY good, and have a long enough cord so it’s not pulling at my ears like some sort of damned harness… I HATE short earphone cords!

(And while I am on the subject of ear phones, and while I haven’t been zapped in the ear with static this year yet by dry air causing that annoying problem, I wonder how these earphones are going to do in that regard… the Sony’s are unbearable in Winter! Ouch! I wonder if anyone else out there has this problem besides me, and has found a solution?)

First of all, thank you for making me aware of the ACARS app and that you can successfully use it with the CC Skywave. I will add the ACARS app to my growing list of HamRadio/SWL applications and also try it myself!

Your experience with the CC Skywave is very similar to mine. It is a fabulous portable receiver. If it only had SSB and sync detection, it would be the ultimate compact portable. The CC Skywave is an everyday carry (EDC) radio for me–either it, or the Sony ICF-SW100, accompany me everywhere in my Timbuk2 messenger bag.

Regarding static discharge from headphones, I don’t think I’ve ever had this happen to me; sounds annoying, though! I suppose walking in dry winter conditions with a thick winter jacket could increase chances of discharge. Perhaps the in-ear design of the included CC earbuds–with silicon earpieces–will minimize and insulate you from this problem? Let us know!

Thank you for your assessment of the CC Skywave, William!

Peter recommends the Sony SRF-S84 and SRF-18 ultralights

In reference to our post about the Sony SRF-39FP and SRF-59, SWLing Post reader, Peter, writes:

The Sony SRF-S84

As usual a very interesting post.

I sold most of my collection of receivers some years ago but I’m still interested in AM DXing and especially ultralight DXing (thats why I have three SRF59).

May I draw your attention to other receivers as well?

The famous CXA1129N chip has been built into the SRF-S84 and into the SRF-18 as well. I use the SRF-S84 during sports. As the ferrite rod is even smaller than in the SRF-59 AM reception is a little bit less sensible but FM shines with mega sound.

The SRF-18 is my favorite travel radio!! It runs endlessly on two AA-cells, has built in stereo speakers, audio-in and audio-out, a rather large dial which is easy to use and due to a larger ferrite rod it is very very sensitive on medium wave.

Thank you, Peter! Perhaps the SRF-18 can take the place of the SRF-59 as an affordable MW ultralight that is still in production. The Amazon price for the SRF-18 is $32 US–quite affordable. While I don’t need another ultralight, that price makes it very tempting.

The SRF-S84 reminds me of a super compact radio I used to sneak into my fifth grade class. I would listen to the radio during class by concealing the receiver in an interior jacket pocket and snaking the earphone cord through my sleeve. I would then rest my head on my left hand where the earphone was conveniently located.  Somehow I never managed to get caught.

While I’m sure my education suffered a little that year, it still makes for good memories!

Jeff’s Updated Sangean PR-D4W Review

Sangean

Many thanks to Jeff McMahon, from the Herculodge, who shares an update to his Sangean PR-D4W review.

The good news is that Jeff continues to be impressed with the PR-D4W and ranks it above the venerable C.Crane CCRadio-2E in almost every category. At $64.50 on Amazon, the PR-D4W is a much better value.

Follow this link to his review:

Jeff gives high marks to the Sangean PR-D4W

Sangean

My pal, Jeff McMahon, over at the Herculodge, has just posted a video review of the Sangean PR-D4 portable radio. In summary, he writes:

“It’s a great radio with top FM, AM, and speaker sound. It blows away my C.Crane Radio-2E. Lack of illumination, however, makes it less than ideal as a bedside clock radio.”

Wow! I’m most impressed that Jeff places the PR-D4W (which retails for $69 on Amazon) above the venerable CCRadio-2E (which retails for $169 on Amazon) in terms of AM performance.

I just checked and it appears that Universal Radio also retails the PR-D4W for $69.95.
