Video: Moshe captures an echo in Radio Kuwait signal

Many thanks to SWLing Post contributor, Moshe Ze’ev Zaharia, who submits the following videos of his reception of Radio Kuwait at 10:30 UTC on April 6, 2018 from his home in Israel.

Moshe notes that the signal was of blowtorch strength and, for at least 45 minutes, there was an ever-present delay/echo. Moshe’s receiver is a (beautiful!) Zenith Trans-Oceanic T600 and his antenna a 15 meter wire:

Many thanks for sharing, Moshe!

Did anyone else note this echo? I wonder what happened at the Radio Kuwait transmitting station to make this happen?  Or, perhaps, it was a fault with the audio feed they received? Please comment!

Clyde Haehnle: Loss of a broadcasting icon

Museum Icon Passes Away

The National Voice of America Museum of Broadcasting mourns the loss of one of its major leaders and benefactors. Clyde Haehnle passed away peacefully on Sunday, April 8th.   Over the years, this icon in the development of broadcasting technology, not only locally but nationally, was the driving force behind the museum.

A veteran broadcasting engineer and executive, Mr. Haehnle was instrumental in the early meteoric development of Powel Crosley’s WLW. While working at WLW, fresh out of electrical engineering school at the University of Cincinnati, he was assigned in 1942 to work on design and construction of VOA-Bethany Station, the transmission facility of the newly- minted Voice of America. The facility operated from 1944 thru 1994 and beamed programs worldwide from the highest power shortwave transmitters built in the world at that time.

The rhombic antenna design requiring extensive mathematical calculations fell to Mr. Haehnle. His work accomplished with pencil, paper and a slide rule resulted in some of the most efficient antenna arrays ever built and enabled the VOA programs transmitted from the hilltop north of Cincinnati to be heard by eager listeners worldwide. P of Engineering at AVCO Broadcasting. He held many patents in electronic technology and continued to be a curious and thoughtful proponent of technology well into his ninth decade.

Mr. Haehnle’s untiring leadership and support has enabled the National Voice of America Museum of Broadcasting to develop into a rich educational institution celebrating the role broadcasting has made in the dissemination of programs globally encouraging democratic principles to truth-starved audiences.

The Museum plans a celebration of Mr. Haehnle’s extraordinary life later this spring.

Shortwave Radio Recordings: Ham radio contacts between W2PVF (SK) and two Antarctic Stations, circa 1974

Palmer Station (Photo Credit: Ryan Wallace and the USAP)

Many thanks to Bill Hemphill (WD9EQD) who is one of our newest contributors at the Shortwave Radio Audio Archive (SRAA). Bill approached me at the Winter SWL Fest this year noting that he has a wide variety of radio-related audio recordings to share with the SRAA and the SWLing Post.

This week, Bill shared two fascinating tape recordings he originally acquired from an estate sale box.  These recordings were originally made in 1974 by the late Jim Hayward (W2PVF) in Absecon, New Jersey (USA) with two different ham radio stations in Antarctica.

This first recording is between W2PVF and KC4AAC of Palmer Station. The audio starts mid conversation:

The second recording is between W2PVF and LU1ZE of the Argentine Antarctica Station. The operator at the microphone is W1PV. The recording even includes a phone patch:

Bill, thanks so much for sharing these recordings–I thoroughly enjoyed them!

I’m so impressed with the audio and signal quality of the Antarctic stations.  In 1974, we were approaching a solar minimum in Solar Cycle 20. Still, I bet conditions were better than anything we’ve seen in over a decade!

I’m curious if any Post readers have ever made contact with either of these stations or even know the operators in the recordings? Bill notes that  Jim (W2PVF) was president of the local Atlantic City Electric Company for many years. Would be fun to share these recordings with the some of the original operators, if they’re around!

Recommending the Tecsun PL-880 over the Sangean ATS-909X

Many thanks to SWLing Post contributor, Direwolf131, who recently commented on one of the Sangean ATS-909X reviews in the Post archives.

Direwolf131 writes:

I’m a few years after Steve’s comments but I will have a go at it, at least anecdotally speaking. I’ve owned a half dozen Sangean ATS-909’s, which includes two of the 909X’s, and one super-909 from radiolabs. The 909X is the finest looking portable I have ever seen or lain hands upon, and that includes several Sony’s that I still think of as neat looking, I had the white cabinet 909X first and then the much more striking (to my eyes) black cabinet 909X after returning the first one due to rock hard buttons.

They are both extremely attractive, and exceptionally well made, especially by today’s cheap Chinese standards. I must confess that I also still find the original 909’s almost equally neat looking, though not quite sporting the same robustness of build.

The 909x’s sound wonderful on MW & FM, and its a decent performer reaching out to fairly distant FM stations. Unfortunately that is largely the best of the radio, its performance on MW & SW is best described as pathetic, and not just due to being deaf, it has a lot of noise, even when attached to the superb RF systems tuned EMF antenna. The older 909 is also to my experience substantially better then the 909X when matched up to a serious outboard antenna, such as the above EMF, I found this difference especially surprising, its not even close.

The PL-880 from Tecsun blows it away on SW and MW sensitivity, while also offering the superb advantage of genuinely ECSS tuning anything on MW & SW, you cannot decently receive any MW or SW signal via ECSS with the 909X as its SSB can only be fine tuned to 40 Hz, which is terribly disappointing, you can zero beat the little Tecsun easily. serious ECSS capability is to my mind a much more attractive option then a sync circuit, and unfortunately with the beautiful little Sangean 909X you get neither.

I do hope anyone who happens upon this pays attention, because for the money the PL-880 is far and away the better performer, in fact my little 1103 from Degen/Kaito out performs the 909X, as does my Grundig Yacht Boy-400, and my Sangean ATS-803A. Its my great hope that Sangean seriously upgrades these deficiencies in the otherwise gorgeous 909X, its circuitry is noisier than the old 909 and its not nearly not as sterling a performer hooked up to household current and a decent outboard antenna as the old 909, its 40 hz tuning SSB once a great reason to buy a 909, is no longer competitive, especially against the superb PL-880 which again is capable of excellent ECSS even by Icom R75 standards, Sangean would do well to drastically improve the SSB performance of the 909X.

I hope this helps, I liked the original review up top, but again its several years old, and the ATS-909X is now known to be clearly outclassed by the more affordable Tecsun, actually by the PL-660 to boot, I really hope Sangean addresses the issues, its such a beautiful receiver, you just want it to be as good as it looks, unfortunately it’s not!

Thank you for sharing your evaluation and comments!

The Sangean ATS-909X is an interesting radio indeed. Almost everyone loves the design, audio and overall quality of the 909X.  Yet performance reviews are somewhat polarizing: some 909X owners claim the 909X has strong performance characteristics on shortwave, while others believe it’s almost deaf. Your findings coincide with mine from the Mega Review where I pitted the ATS-909X against the Tecsun PL-880, PL-660 and Sony ICF-SW7600GR. In that review, where I relied on a whip antenna, the 909X was noticeably less sensitive than the other three competitors. Based on the premium one pays for the 909X, I was surprised.

I have learned over the years, however, that the 909X can handle larger outdoor antennas and doesn’t easily overload. Additionally, the 909X requires a fresh set of batteries for optimal performance/sensitivity. Some users have even modified the radio with a 4:1 impedance transformer–click here to read a post/comments about this mod.

I would love to see Sangean produce an updated/upgraded version of the 909X, but at this point I’m not exactly holding my breath. I’ve heard that they’re slowly pulling out of the market. Hope I’m proven wrong because I’d love to see a new shortwave set from Sangean.

The Professor reviews the XHDATA D-328

Many thanks to SWLing Post contributor, The Professor, who shares the following review of the XHDTA D-328:

First off, this is the best radio I’ve ever operated… that cost me less than ten dollars new. When I saw the promotion on the SWLing Post for free or half price radios, I had to bite, especially because the deal was that the first ten to respond would get a free XHDATA D-328. They told me I was the 15th caller, so I was allowed one for half price. And since they were going for just under fourteen bucks on Amazon, it felt like it was almost free.

Of course, I didn’t expect much. But as they wanted the people who received these free or very inexpensive little radios to leave reviews, I figured the Chinese manufacturers knew there were some good features radio folk might notice. And there are. And I’m not sure if I’ll post part of this brief review on Amazon, but I’ll do so here in this comment.

If you want a radio that will reliably pick up local AM and FM stations and play some MP3 files, this will work, and work pretty well. And it doesn’t sound bad at all for the size. I personally don’t have much love for these new analog-style tuning DSP radios, but I suppose people who aren’t as radio wise as readers of the SWL Listening Post won’t notice the less than poetic effects of moving between stations on these sets. Most probably tune in their desired stations and just listen to it, and this radio does this well enough.

I don’t really listen to FM much, but the XHDATA D-328 seems adequate enough. And with headphones on it sounds quite rich on FM. AM isn’t bad either, but it’s far from selective. I was able to dig out clear channel regional biggies like Zoomer Radio at 740kHz and WHAS at 840kHz in Louisville from here in Brooklyn at night, but in between often easy to find fifty-thousand watt stations like WBBM or CKLW weren’t there. The DSP tuning just defaulted to the next local station like WNYC or WABC when I turned the dial.

Shortwave was worse. Beyond the U.S. powerhouses like WWCR this radio doesn’t seem a very worthy shortwave set for those of us in North America. But I can imagine in that in third world countries where international and local broadcasters still target broadcasts that this radio might be an inexpensive way to access that programming.

I must admit that listening to MP3 music files was kind of pleasing. Again, the audio is really good for a radio at this price point. However you are listening blind, there’s no screen to tell you what you’re hearing, and no shuffle function to make a folder full of MP3s into unique sequences of songs each time. What you get are the songs in the alphabetical order of the file titles, although you do have the option to jump ahead 10 files before or after the one you are playing. So the best use of an MP3 player like this would be to listen to podcasts or whole radio programs with it. What I would do is copy the files onto the SD card and then perhaps number the filenames in the order I would like to hear the shows.

So, for the price there’s not a lot to complain about. People have already mentioned the off-center small kickstand, and that’s a little cheesy. But the tuning thumb wheel moves smoothly thru the imperfect DSP tuning function, and the volume thumb wheel is actually analog which make it much easier to get the exact volume you want out of this radio. But the sliding band selection switch under the tuning scale is a bit worrisome, as I’ve had a few cheap Chinese radios with a switch like this and just normal use eventually rendered them unable to switch bands adequately. This one feels a little bit more stable then they did, but time will tell.

All that said, there are radios that are not too much more expensive than this radio that offer much more in a number of ways. The small and inexpensive analog Tecsun radios from a few years ago are a case in point. Selling for twenty to thirty dollars, those multi-band radios are a little challenging to tune (a stiff thumb wheel on some), and the tuning scale may be a little off and they may drift a little, but the analog tuning is a much better experience. And you can DX with them. I remember listing to All India Radio with a decent signal one afternoon on my Tecsun R-9710.

There’s a lot of similar analog radios which I believe are probably just about the same radio – the Tecsun R-9012, the Tecsun R-911, the Tecsun R-909 and the Kaito WRX-911, among others. Once you get a look at these you’ll recognize other similar radios in this family. I’d say they’re the best really cheap receivers I know of. They generally run between twenty to just over thirty bucks. I believe these radios appeared on the scene in the early 2000s.

I have this fear that they’ll start turning these radios into DSP sets. That would be a real shame, but I’ve heard no mention of that. However I did notice that the marketers of the XHDATA D-328 didn’t even mention that it was based on a DSP chip. And Chinese manufacturers are notoriously not very open about how they are altering radios that they’re putting out, so be aware of that.

As far as MP3 playback, the one radio I would really recommend is the Meloson (or Tesslor) M8 (or the Meloson M7 or S8 if you can find one). It’s simply the best audio you’ll hear in a really small radio, AND you can shuffle the MP3 files in a folder with these. While it only give you the sequential number of the song in the display, it will generate a unique sequence of songs each time you shuffle. Fill a folder on a card full of songs and let it rip. It’s the perfect micro music player if you make a good folder of music. And the DSP radio in these is not bad either. It’s digital, not fake analog tuning, and most AM clear channel targets you can usually find at night in your region will show up on these. They used to go for less than thirty bucks, but right now I see they cost close to fifty dollars.

Two other radios I have that I can recommend for MP3 playback, are the Tecsun ICR-110 and the Tivdio V-115. Neither one offers playback shuffle, but they will play the files in alphanumeric order just fine. But they both have a cool feature in that you can press a button and record the broadcast you’re hearing as an MP3 file. And they both also sound great. The Tivdio has incredible sound for a tiny radio, but the ICR-110 is even more impressive. I believe it has the same speaker setup as the much more expensive Tecsun PL-880 and it also has similar warm and clear audio.

The reception with the V-115 is OK, nothing stellar, but the ICR-110 is kind of a monster on medium wave. I’ve been impressed. The ICR-110 is rather big compared to the other radios I’ve mentioned, closer to the PL-880 in size, but quite a bit lighter. The ICR-110 used to be cheaper, but can be found for around forty bucks. The Tivdio V-115 still goes for just under twenty if you look around. A bargain. Tecsun, Tivdio, Degen and other Chinese manufacturers have all sorts of inexpensive radios for sale out there, and others I haven’t used or mentioned might be quite good as well. If one appeals to you, do a little online research.

Of course, since I’m talking about small and inexpensive radios I should mention that the Tecsun digital DSP sets like the PL-310ET, the PL-360, PL-380, PL-390 and other variations are all amazing inexpensive radios that will run you around 35 to 50 bucks. The ultralight DX community loves these things, and for good reason. And there’s a version of the PL-390 that plays MP3 files from an SD card and another that offers bluetooth playback. No, none are perfect, but they’re solid sets, and all would have been dream radios thirty years ago.

So, that’s my evaluation of the XHDATA D-328, well worth fourteen dollars, but for a few dollars more you can get radios with similar features that do much more. It’s small, it doesn’t sound bad, and it’s fairly well-built. It will pick up all your favorite local stations and play all your MP3 podcasts effortlessly. Not bad. Like I said, it’s the best super cheap radio I’ve ever used.

Excellent review!  I’m impressed that the D-328 has enough AM performance to grab some  night time clear channel stations. It’s disappointing, however, that it lacks performance on the shortwave bands.

Thanks for posting your review–always great to hear from The Professor!
