Shoot-out results: Top ultra-portable shortwave

Tecsun-ShootOutThanks to all who participated in our ultra-portable shoot-out! A little over a week ago, I posted recordings of shortwave broadcasts, weak and strong, in an attempt to evaluate which recording–thus which radio–our listeners prefer. I conducted this test on the three radios pictured above: the Tecsun PL-310ET, the CountyComm GP5/DSP (Tecsun PL-360), and the Tecsun PL-380–among the most popular ultra-portables currently on the market. This test was “blind” in the sense that all three radios evaluated were merely labeled “Radio 1,” “Radio 2,” and “Radio 3,” respectively.

The samples

To refresh your memory, I’ve embedded the audio samples below for you to hear; but if you haven’t yet heard them, I encourage you to read our previous post before doing so. (If you’re already heard the recordings, simply skip this section.)

And now…the results!

The following chart shows how each radio scored out of a total of 106 (wow!) survey responses:

ShootOutRadios

Let’s start with the radio that scored lowest in this contest…

Radio 3: the CountyComm GP5/DSP (a.k.a., the Tecsun PL-360)CountyCommGP5DSP

Interestingly, the GP5/DSP consistently came in last in every category. I think a few factors outside of receiver performance led to this.

For some reason, the recorded audio of the GP5/DSP sounds out-of-phase.  Several of you noted this. The resulting sound almost mimics a “stereo” effect. No matter how many times I made recordings on the GP5/DSP, this feature predominated, and I eventually assumed it to be characteristic of this radio’s DSP.

But I’m wondering now, however, if there might be oxidation on one of the headphone jack conductors, or if the headphone jack on my unit is somehow faulty–?  Because of this, before conducting the medium wave shoot-out, I’ll try to clean the conductors with a little Deoxit to see if it makes a difference.

Unlike the PL-310ET and PL-380, the GP5/DSP can’t change AM bandwidths. On the strong recordings, I widened the bandwidths of the PL-310ET and PL-380 to 6 kHz; this improved their audio fidelity. On weak signals, I narrowed the bandwidth to 3 or 4 kHz, keeping both at the same level as I did so. While the GP5/DSP’s fixed bandwidth is well chosen, it simply couldn’t compete with the wider filters of the other two radios on strong signals.

Though the GP5/DSP (Tecsun PL-360) came in last, the irony is that most people who made comments on the survey form actually mentioned that the GP5/DSP was also a strong contender. Here are a few responder’s comments:

  • “The bassiness of Radio 1 was pleasing to listen to, but the clarity of radio 3 was also pleasing. All three sounded very good.”
  • “I was divided–Radio 1 seemed to provide the better audio on the stronger stations (not as muddy) yet Radio 3 beat it out on the weak stations and seemed to hold the station steadier (less fading) thereby providing a better audio to hear and understand.”
  • “I think if I were to place these three radios in order of “listening pleasure” based on the provided samples, my order would be 3, 1, 2.”
  • “By a small margin Radio 3 seemed to have the best signal to noise ratio and general audio quality across the range of signal strengths.”

Also notable:  the GP5 has one very distinct advantage over the other two radios, something that wouldn’t have been noticed in this test: its ETM function, which scans the whole band then automatically stores stations to temporary memory, is almost two times faster that that of the other radios. It also seemed to be equally accurate.

So, who would buy the CountyComm GP5/DSP (Tecsun PL-360)? Someone who likes this radio’s form factor, it’s stable AGC, and quick ETM scanning. Keep in mind, we are comparing this model with two of the best radios under $60, in my opinion. Had we compared the GP5 with most other sub-$60 radios, it might have won that shoot-out, and with ease.

Radio 2: The Tecsun PL-380

Tecsun-PL-380

The Tecsun PL-380 came in a very consistent second place in this shoot-out.

The ‘380 is one of my favorite portables on the market; for many years, it has been my go-to radio for one-bag travel.

Before recording the shoot-out, I guessed that the PL-380 might take first place. But up to this point, I had never actually compared it with either of the two other radios in this shoot-out. Listening to the blind samples, I tend agree with the results.  Still, the PL-380 is a great value and a fun little radio, one I can still easily recommend for travel.

Radio 1: The Tecsun PL-310ETTecsun PL-310ET

As you can see from the graph, the Tecsun PL-310ET won our shoot-out in every category–and by a fairly wide margin:

UltraPortableShootOut

While comparatively few participants’ comments were specific to the PL-310ET (“Radio 1”), it’s interesting that these most often made note of this radio’s very close resemblance to the PL-380 (“Radio 2”).

The PL-310ET had only a slight advantage over the PL-380 to my ear, but it was enough; so along with most survey respondents, I took note of that advantage.

Now, I know this much: when people ask me whether they should purchase the PL-380 or PL-310ET, I think I’ll suggest the PL-310ET. In the end, it makes for a better travel radio because it also has an external antenna jack, one of the few sub-$60 radios that has this useful feature.

In summary, the Tecsun PL-310ET is truly a fantastic ultra-portable radio, and, at $48 – 52 US, it’s a real bargain, to boot.

Coming soon…our medium wave shoot-out!

When I find the time in the next month or so, I plan to test the same radios in a medium wave (AM) shoot-out. Weak-signal medium wave will put AGC circuits and internal ferrite antennas center stage. Please be patient, however, as these tests actually take time to put together and evaluate.  Again, your participation will be most welcome!

Video: Dave’s “Sproutie” home-brew regenerative receiver in action!

My good buddy, Dave Richards (AA7EE), has just posted videos of his home-brew regenerative receiver–nicknamed “The Sproutie.” [You may recall an earlier post about this very receiver.]

Below, you’ll find a video where Dave tunes in broadcasters with The Sproutie–she certainly has ears!

Dave, that’s a simple, beautiful little radio you’ve built there.  I love the HRO knob–form and function at its best.

Readers: be sure to check out Dave’s full post about the Sproutie along with another video. If you haven’t yet, bookmark Dave’s blog–it’s a good one!

New RadioShack portable AM/FM/SW radio?

RS-ShortwaveRadio

SWLing Post reader, Paul, points out this RadioShack model 2000669 portable radio and asks, “Is this a new RadioShack shortwave radio?

Very good question! Though I haven’t been inside a RadioShack in a couple of months, I’ve never noticed this portable on their shelves. In fact, I don’t even recognize the form factor  as a re-badged Tecsun or Degen.

Has anyone purchased the model 2000669 from RadioShack?

Name that dial!

Mystery-Radio-DialYesterday, I acquired another antique radio (yes, a “boat anchor”) for my modest collection of vintage receivers. I took a quick close-up photo of its backlit dial (above).

For fun, I’m curious if any SWLing Post readers can name the radio sporting this dial? If you want to give it a go, please comment below.

CountyComm GP5/SSB: videos and photos

Many thanks to Nick at CountyComm who recently sent me a short video he made of a prototype GP5/SSB in action:

Nick also shared a few close-ups of the GP5/SSB:

Ultra Portable Shoot Out: Which radio do you prefer?

Tecsun-ShootOut

I’ve been traveling this week, but found the opportunity to hold another shortwave portable shoot-out. (You may recall the weak signal shoot out earlier this year.)

This time, I’m comparing three popular ultra portable radios, namely, the: CountyComm GP5/DSP (a.k.a. Tecsun PL-360), the Tecsun PL-310ETand the Tecsun PL-380.

This particular trip afforded me a bit of time to test these wonderful little portables in a relatively scenic environment, on balcony overlooking the Atlantic. And even though propagation has been somewhat dismal this week, I had so much fun recording these samples, I recorded several for comparison.

Which of the three radios do you prefer? Listen to the recordings, then vote! You’ll find a survey form at the bottom of the page that will allow you to cast your vote for your favorite with weak signals, with strong signals, and your favorite overall.

We’re using a form this time to make it easier to tally the results. If you enjoy this contest–or have any problems–simply comment below.

Stay tuned for a medium-wave shootout in coming weeks!

Note: I will close this survey at 00:00 UTC on Saturday, November 22, 2014.

Sony ICF-SW100: difference between MKI and MKII

Sony-ICF-SW100

In response to our post about the Sony ICF-SW100, Michael comments:

“I’ve found that, with some patience and a willingness to search outside of eBay, that the ICF-SW100 can be found for under $250. It’s more than a fair bit of money for a shortwave receiver. If I had to take a guess at why it has held its value so well it would most likely be down to the amount of performance and features that still exist in a radio so small.

It is rather sensitive but even more so with an active external antenna or just a long wire attached to either the external antenna jack or the whip itself. It seems that the size of the whip itself (due to space constraints) limits the sensitivity of the radio. I use mine with a PA0RDT mini whip that I have constructed and the two work well very together. If you add a small outboard filter such as a NEScaf you have an entire station in miniature.

The fault with the hinges was only found on the MKI models. The MKII model was released by Sony primarily as a revision to solve the ribbon cable issue. You can tell a MKII from a MKI by looking at the lower right hand corner of the display part of the clamshell. If you see a rectangular shaped notch then it is a MKII. That notch is there for preventing the ribbon cable from being pinched between the two halves when the case is shut.

If you’re looking for a radio that is feature laden as well as exceptionally small then the ICF-SW100 is still an excellent choice.”

Many thanks for your comment, Mike!
