Weak signals: Which radio do you prefer?

SideBySide-FourRadios

I’m in the process of reviewing a number of shortwave portables and pitting them against each other. Sometimes, it can be very difficult to decide which radio is better–especially if you have more than two radios to compare at a time.

What I’ll often do to help level the playing field is to make an in-line recording of each radio (via my Zoom H2N handy recorder) with the mic and volume levels equal. I then tune to the same frequency with similar filter settings (wide, maximum RX gain, antennas fully extended, etc.).

I also like comparing radios while listening to weak signals and/or when conditions are less favorable. Those were exactly the circumstances yesterday when I pitted four radios against each other: the Sangean ATS-909X, Tecsun PL-660, Tecsun PL-880 and the Sony ICF SW7600GR.

I found a weak signal from Radio Romania International on 11,975 kHz. Normally, the signal would have been stronger, but propagation was rough and QSB (fading) was pronounced at times. Under these conditions you get the opportunity to hear how the AGC circuit handles fading and troughs, how the noise floor sounds as conditions change and note the overall sensitivity.

While I give priority to a receiver’s sensitivity and selectivity, there’s more to evaluate–for example, sometimes the more sensitive radio may be less pleasing to listen to.

Below are three recordings of Radio Romania International made from three of the four radios tested (I did not include one of the four radios that was notably less sensitive). These are audio snapshots, but represent what a listener would hear via headphones during similar conditions. All recordings were made within a four minute period of time.

[Update: Check out the results of this test.]

Which of the three recordings do you prefer? Which radio do you find handles these unfavorable conditions best? Why do you prefer one over the others?

Please add your comment below, or contact me via email with your favorite and any comments. I’m also very interested in which one you believe is second best. I’ll tally up the results in one week and will reveal which radio came out on top!

Tecsun PL-660 + Nevada EFW-2 = Winning Combo

Shortly after posting my Traveling Light, SWLing Right article yesterday, @LondonShortwave shared a video of the portable set up he uses for SWLing in London public parks:


Click here to view a video of his Tecsun PL-660/Nevada EFW-2 combo in action.

The antenna @LondonShortwave uses in the video is the Nevada EFW-2 (below). To keep the PL-660 from overloading he either sets the PL-660 sensitivity switch to “Normal” (rather than “DX”) or uses the Global AT-2000 coupler shown in the video.

Traveling light, SWLing right: the best shortwave radios for travel

This article originally appeared in the March 2014 issue of The Spectrum Monitor Magazine.


SWL Travel Gear - Grundig G6

With spring around the corner, my thoughts drift toward the outdoors…and especially, toward travel. Those who know me know that I love travelling, anywhere and everywhere–and that I prefer to travel light, with only one bag. In fact, I can easily live for two weeks out of a convertible shoulderbag/backpack (the Timbuk2 Wingman) that’s so compact, I can fit it under the the seat of even the smallest, most restrictive aircraft. I never have to check luggage unless the nature of my travel requires extra supplies (I run Ears To Our World, a non-profit that donates radios and other technologies to powerless regions in the developing world).

My Timbuk2 Small Wingman is very compact, yet holds everything I need--including radio gear--for two weeks (or more!) of travel.

My Timbuk2 Small Wingman is very compact, yet holds everything I need for two weeks (or more!) of travel.

So, why not pack everything you could possibly ever want on a journey?  While this remains an option, travelling light has many advantages over the take-it-all traveler’s method. First, it gives one incredible freedom, especially when travelling by air or train.  I never have to worry about being among the first to be seated in an aircraft, nor do I worry about my luggage not making a connection when I do.  Second, it’s kinder on the back and shoulders, and easier to maneuver wherever I go–no wheels required–whether in a busy first-world airport or bustling third-world street market.  Third, I always have my most important gear right there with me.  And finally (I must admit) I find light travel to be fun, an entertaining challenge; the looks on friends’ faces when they meet me at the airport to “help” with my luggage is, frankly, priceless.  Seeing me hop off a flight with my small shoulder bag, friends ask in bewilderment, “Where’s your stuff?” It’s music to my ears.

You would think that having such self-imposed restrictions on travel–carrying a small, light bag–would make it nearly impossible to travel with radio. On the contrary!  Radio is requisite, in my book–er, bag.  I carry a surprising amount of gear in my small bag:  once at an airport security checkpoint, an inspector commented, “It’s like you have the contents of a Radio Shack in here–!” But more significantly, each piece–and radio–is carefully selected to give me the best performance, durability, versatility, and reliability.

So what do I look for in a travel radio? Let’s take a closer look.

Travel Radio Features

While the CountyComm GP5DSP only has average performance for its price class, it has three different ways of auto tuning stations quickly, an alarm function and the display will even indicate the current temperature. Its unique vertical, thin body might be easier to pack at times, depending on your travel gear.

The CountyComm GP5DSP has three different ways of auto tuning stations quickly, an alarm function and the display will even indicate the current temperature. Its unique vertical, thin body might be easier to pack at times, depending on your travel gear.

In a travel shortwave radio, I search for features I wouldn’t necessarily pick for home use, where I’m mainly concerned with raw performance. I don’t want to carry an expensive receiver while traveling, either: $100.00 US is usually my maximum. This way, if I accidently break the radio (or my gear gets stolen), I won’t feel like I’m out very much money.  I also prioritize features that benefit a traveler, of course; here are some that I look for:

  • Small size: Naturally, it’s sensible to look for a travel radio that’s small for its receiver class for ease in packing.
  • Overall sturdy chassis: Any travel radio should have a sturdy body case that can withstand the rigors of travel.
  • Built-in Alarm/Sleep Timer functions: While my iPhone works as an alarm, I hate to miss an early flight or connection, so it’s extra security when I can set a back-up alarm.
  • Powered by AA batteries: While the newer lithium ion battery packs are fairly efficient, I still prefer the AA battery standard, which allows me to obtain batteries as needed in most settings; a fresh set of alkaline (or freshly-charged) batteries will power most portables for hours on end.
  • Standard USB charging cable: If I can charge batteries internally, a USB charging cable can simply plug into my smart phone’s USB power adapter or the USB port on my laptop; no extra “wall wart” equals less weight and less annoyance.
  • ETM: Many new digital portables have an ETM function which allow auto-scanning of a radio band (AM/FM/SW), saving what it finds in temporary memory locations–a great way to get a quick overview of stations.  (As this function typically takes several minutes to complete on shortwave, I usually set it before unpacking or taking a shower. When I return to my radio, it’s ready to browse.)
  • Single-Side Band: While I rarely listen to SSB broadcasts when traveling, I still like to pack an SSB-capable receiver when travelling for an extended time.
  • RDS: Though an RDS (Radio Data System) is FM-only, it’s a great feature for identifying station call signs and genre (i.e., public radio, rock, pop, country, jazz, classical, etc.)
  • External antenna jack: I like to carry a reel-type or clip-on wire external antenna if I plan to spend serious time SWLing. Having a built-in external jack means that the connection is easy, no need to bother with wire and an alligator clip to the telescoping whip.
  • Tuning wheel/knob: Since I spend a lot of time band-scanning while travelling, I prefer a tactile wheel or knob for tuning my travel radio.
  • Key lock: Most radios have a key lock to prevent accidentally turning a radio on in transit–but with a travel radio, it’s especially important to have a key lock that can’t be accidentally disengaged.
  • LED flashlight: Few radios have this, but it’s handy to have when travelling.
  • Temperature display: Many DSP-based radios have a built-in thermometer and temperature display; I like this when I travel anytime, but especially when I’m camping.

While I don’t have a portable that meets 100% of the above travel radio wish-list, I do have several that score very highly.  I also rank my travel radios by size, as sometimes limited space will force me to select a smaller radio.

Here are a few of the radios I’ve used and/or evaluated for travel–I’ll break them down by size. Note that all portable radios have alarm/timer functions, unless noted otherwise.

My Tecsun PL-380 and the small Eagle Creek pack that also holds my Zoom H1 recorder, earphones, audio cables, external antenna, spare batteries and Kindle.

I often grab the Tecsun PL-380 for travel. It’s an ultra-portable that truly performs and even has a selection of six AM bandwidths.

Ultra-portable:

Full-Featured Portable:

I have also been known to travel with an SDR (software defined radio), especially if travelling to an RF-quiet location where I could make spectrum recordings. While SDRs all require a computer (laptop) to operate, those best suited for travel derive their power from the same USB cable plugged into the PC. Neither of the SDR models below require a power source other than what’s provided by their USB cable.

The RadioJet is an excellent travel radio: it’s an excellent performer, über-rugged and is powered by one USB cable.

“Black box” radios (SDRs & PC-controlled radios):

  • RFSpace SDR-IQ • Pros: Small size, works on multiple operating systems (Windows, Mac, Linux) • Cons: front end can overload if close to strong signals
  • Bonito RadioJet • Pros: Great performance, low noise floor, good audio, flexible graphic interface; • Cons: Windows only, limited bandwidth on IF recordings, no third-party applications (note that the RadioJet is technically an IF receiver). Check out our full review.
The CommRadio CR-1

The CommRadio CR-1

Tabletop:

Seriously? A travel-ready, full-featured tabletop–? Until last year, I would have argued that it was impossible to travel lightly with a full-featured desktop radio in tow.

My view changed when I got my hands on the CommRadio CR-1 tabletop SDR. Indeed, other than it being pricey ($600, as compared with $100 portables) this rig is ideally suited to travel!

The CR-1 has an array of features–most everything you’d expect from a tabletop radio–and even covers some VHF/UHF frequencies. Its built-in rechargeable battery not only powers it for hours at a time, but meets the strict airline standards for battery safety. The CR-1 can also be powered and charged via a common USB cable. It’s also engineered to be tough and is almost identical in size to the Tecsun PL-880.

CommRadioCR-1PowerKnobThough I’ve never needed to do so, you can even remove its resin feet to save still more space. Its only less than travel-friendly feature is the fact that it’s quite possible to accidently power up the CR-1 by bumping the volume button during travel–a problem easily remedied, however, by simply twisting an insulated wire around the stem of the volume knob (see photo).

The importance of a Go-Bag

The SpecOps PackRat

The Spec-Ops Pack-Rat

I keep a dedicated “go-bag” with radio and supplies–specifically, the Spec-Ops Brand Pack-Rat–packed and ready to travel, at the drop of a hat. Why? First of all, I know exactly what I’ll be taking, no need to ponder if I have everything.

Inside the bag, everything has its place: my portable SW radio, my Android tablet, my D-Star Icon ID-51a HT, DVAP (DV Access Point Dongle), my Zoom H2n Handy Recorder, earphones, charging cables, batteries, small notebook, clip-on wire antenna, etc.

If something’s missing, there’s an obvious blank spot in my bag. I also know exactly where and how it fits into my carry-on bag, so if it’s missing, it’s conspicuously missing. Since I’ve been using this go-bag, I’ve never left anything from my pack behind. Incidentally, this is how I pack the rest of my bag, as well: everything has its place, and any gap will draw my attention to exactly what’s missing.

SWL Travel Gear - Spec-Ops Pack-Rat Open

There’s another benefit to having a dedicated go-bag: when flying, before I place my carry-on under the seat in front of me or in an overhead compartment, I can pull the go-bag out of my carry-on and have my Android tablet close at hand with other electronics.  As an added bonus, when going through airport security, all of my electronics can be easily removed from my flight bag by taking out just this kit.

 SWL Travel Gear - Spec-Ops Pack-Rat Contents

I’ve had many versions of the Go-Bag over the years, and they’ve all done a great job. What I love about the Spec-Ops Brand Pack-Rat, though, is the fact that it’s military grade–very durable–opens with all of the main storage pockets on the inside, has a bright yellow interior which makes it easy to see the contents (even in the dimness of a night flight), and it’s just the right size to hold my usual travel gear. The Spec-Ops Brand Pack-Rat also carries a lifetime, no-matter-what, guarantee.

There are thousands of similar packs on the market, and you may already have one, but you should look for something with multiple storage pockets. Small packs I’ve used in the past that only had one or two main compartments made it easy to leave something out when packing.

When I spent a year in France during my undergraduate studies in the early 1990s, shortwave radio was my link with home. I would listen to the VOA–the only source of English I permitted myself to hear–like clockwork, each week. Today, although I travel with a smartphone which can tune in thousands of stations, I always choose to listen to radio. Besides, if the Internet goes down or if–heaven forbid!–your trip takes you into a natural disaster, it’s radio that you will turn to to stay safe and informed.

If you take anything away from this reading, I hope it’s that even when you’re presented with travel restrictions, you won’t hesitate to take your hobby, in the form of a portable radio and a few accessories along. It contributes measurably to the fun of travel, as I’ve discovered when I’m able to tune in local and international stations so different from those I hear at home.  Or sometimes, it’s just the opposite–it’s the chance to pick up a favorite broadcaster or program while you’re on the road.

After all, for me and other travelers like me, the world’s familiar voice is radio.

Universal Radio lowers price of Tecsun PL-660

PL-660Universal Radio has lowered the price of their Tecsun PL-660 to $109.95. Even with $9.95 shipping, this is still less than the current Amazon price of $129.99.

Note that eBay still has some PL-660s available for $101 shipped, but there would be no guarantee of receiving the radio by Christmas day.

A review of the Tecsun PL-880 portable shortwave radio

Tecsun-PL880-SWLing-Post-0510
I have never seen such a eager response and extraordinary anticipation over the announcement of a new portable radio as with the new Tecsun PL-880. And I’m not surprised.  You see, it has been a couple years since a really good portable radio has been introduced to the market. Plus,Tecsun has proven itself a competent radio manufacturer; the predecessors to the PL-880–i.e., the PL-660 and PL-600–are both excellent portables (I own both). Their smaller DSP radios are favorites of travelers and ultralight enthusiasts.

As I was telling Jeff, over at the Herculodge blog, reviewing the PL-880 was much like attending the opening night of a play. My wife, who has worked in theatre, once told me, “the audience wants the actors to perform well.” The moment I held the PL-880 in my hands, I felt the same: I really wanted this to be a great performer, a new radio companion with which I could track down signals both weak and strong.

But what does the PL-880 actually deliver? Let’s take a look…

Drumroll, please….and now, the PL-880

Tecsun-PL880-SWLing-Post-0515I purchased/pre-ordered my Tecsun PL-880 from my favorite eBay seller, Anon-Co, as I’ve always been pleased with their customer service and delivery time. They’re based in Hong Kong, but my shipping time from Hong Kong via FedEx was only three days before the radio landed in my mailbox.

Unlike past reviews, in which I simply post initial impressions with a full review later, I elected to spill some of my early findings on the SWLing Post as I discovered them.  On the recommendation of a reader, I even photographed the unboxing; I’m glad I did, too, as it felt a bit like taking pictures of a Christmas gift being opened…which was even merrier.

I was happy to see that the PL-880 was packed carefully but with very little waste. Included with the radio was a rechargeable battery, earbud headphones, a wire antenna, and a USB power cable; Anon-Co also also sent a USB wall adapter plug. The carrying case, which holds the PL-880 and its manual, is substantial, reminding me of carrying cases that used to ship with portables some time ago.

The PL-880 is almost identical in size to the PL-660 and PL-600.  The buttons have a highly tactile response, the tuning/volume wheels are very smooth, and feel well-engineered. The display is back-lit and has a dedicated switch on the right side of the radio–meaning that if you turn on the back-lighting, it will stay on, even if you turn off the radio.

The PL-880 has all of the connections and controls I could have wished for in a portable. On the left side of the radio, it has an external antenna jack, a three-position antenna gain switch (DX, Norm, Local), a headphone jack, a line-out jack, and a 5 VDC USB input.  On the right side panel, you’ll find the  main tuning knob, fine-tuning knob, the volume, the back-light switch, and a tone control switch (bass/treble). On the top panel of the radio, there is also a “snooze” button.

When I turned on the PL-880 for the first time and (ironically) tuned to a local AM station on 880 kHz, I was most impressed by the audio fidelity of the 880’s built-in speaker. I believe the PL-880 uses a speaker system similar to the Melson portables: a small mylar speaker cone with some sort of acoustic chamber that produces great bass tones and treble highlights. The sound is room-filling…and delightful.

Performance: First impressions

To begin with, please note that my impressions of performance band-by-band, below, is based on a little over one week of listening. I typically spend longer with radios before publishing a review, but with the holiday season fast approaching, readers have asked for a more rapid response. [That being said, I will of course update and adapt this review over time; but be assured that any significant updates will be noted as such].

Filters

First of all, what truly sets the PL-880 apart from any other shortwave portable currently on the market is its selection of bandwidth filters. On AM, for example, the listener can choose between the following bandwidth settings:

  • 9.0 kHz
  • 5.0 kHz
  • 3.5 kHz
  • and 2.3 kHz

In SSB mode, the choices include:

  • 4.0 kHz
  • 3.0 kHz
  • 2.3 kHz
  • 1.2 kHz
  • 0.5 kHz

Choosing a bandwidth couldn’t be easier: simply press the “AM BW” button to display the current bandwidth setting, then either use either tuning control to widen or narrow the filter, or press the “AM BW” button to cycle through the options.

But how well do these filters work?  Very well, in my opinion. Indeed, I think this is the most innovative and valuable feature of the PL-880. The filter selection gives the PL-880 some of the best selectivity for a receiver under $200 US. To test selectivity, I usually tune to a part of the shortwave broadcast spectrum with two adjacent signals, and see how well the receiver blocks the adjacent signal.  In the case of the PL-880, I took it up a notch and tuned to the CW (morse code) portion of a ham band, as CW signals are spaced much closer together than broadcast signals, thus are more challenging for a receiver to select between. I was delighted to note that the PL-880 not only passed this rigorous test, but performed well above my expectations.

In the video below (which I posted earlier), you can hear what the PL-880 sounds like tuning through a CW pileup. While I would expect more from my ham radio transceiver, I’m most impressed with how well the PL-880 handles these tight conditions. Listen for yourself:

To be clear, though, the bandwidth functionality is not without its quirks. I have yet to determine why it happens, but occasionally when I narrow the bandwidth to, say, 1.2 kHz, then begin tuning–especially when tuning quickly–it opens up to 3.0 or 2.3 kHz. Additionally, with the narrower filters does come a slight audio splatter if a signal peaks during fading (QSB); this happens regardless of the volume setting, and may actually be associated with the PL-880’s fast AGC circuit. I have found that the radio’s three-position attenuation switch is a friend in these conditions, often eliminating the splatter when attenuation is increased.

But, all in all, when it comes to selectivity, the PL-880 is truly a winner.

Hidden features

The new PL-880 ships with a number of hidden features that are, curiously enough, not documented in the operation manual nor indicated on the radio labeling (at least in this first production run of radios). Many of these secret features require that you press and hold a button for about three seconds to enable it.

I’m not sure why Tecsun decided to hide these features. I’ll admit that I’ve really enjoyed hunting for and discovering them–most are terrific additions.  On the other hand, it has been frustrating as well:  I came close to posting an article describing what seemed to be an unfortunate audio stability problem in the PL-880, as I found that when I tuned in a weak station, if the signal level either fell below or climbed above 5, the audio gain would increase or decrease dramatically, making listening very fatiguing. A reader then discovered the hidden “muting threshold” feature, and the story changed. I found that my radio had shipped with a default threshold of “5”–I was able to turn off muting, changing the threshold to zero, and this instantly fixed the problem.

Rather than explaining each hidden feature here, I have added an appendix at the bottom of this review that lists undocumented features…at least those I’ve discovered so far. I plan to list others as I–and/or Post readers–discover them.

Band performance

FM

One of the first FM stations I tuned to was my benchmark NPR station (WFAE) on 90.7 FM, located about 92 miles away from my tuning locale. WFAE is line-of-site from my altitude, but serves as a benchmark nonetheless: my inexpensive receivers can’t maintain a lock on it.  Through the PL-880, the broadcast sounded as if it were local–not an exceptional feat for a quality receiver such as this–but it passed my FM benchmark.  Indeed, I couldn’t even hear a hint of static on the PL-880. I then tuned to several other FM stations I use as benchmarks, and the PL-880 could detect all of them comfortably.

Though I haven’t tried FM DXing with the PL-880, like other recent Tecsuns, it seems outstanding in this regard. (Herein lies the extent of my FM test…More to come.)

AM/Medium Wave

I’ll be the first to admit that I can’t claim to be an AM/medium wave DXer, although recently I have been spending much more time on the band.

With that disclaimer out of the way, I find that the PL-880 certainly holds its own on the AM broadcast band (570-1600 kHz). The PL-880 can hear every local and relatively distant AM station that my C.Crane CCRadio-SW could hear. For this type of armchair listening, the PL-880’s speaker delivers fidelity that is nearly unmatched amongst portables of similar size. It’s most impressive.

But go ahead; listen for yourself: though this video was shot informally with an iPhone, you can still hear the difference in fidelity between the Tecsun PL-880 and the PL-660:

Nighttime listening on AM is on par with the PL-660 in many respects, but I believe I prefer the PL-660 for this, as it features slightly better nulling and more intelligible audio. During nighttime conditions, upon tuning in a wobbly, fickle AM band, the PL-880 sounds a little more muffled or “mushy” than the PL-660. Also, the PL-880’s audio can splatter a bit when the filter is narrowed (again, sometimes moving the attenuation from “DX” to “Normal” helps with this.)

Also, I have to point out that the PL-880’s AGC (auto gain) circuit, as with many other Tecsun models, is just too fast for optimal weak-signal DX on medium wave or shortwave. Tecsun, if you’re listening, please slow it down a bit, or at least provide an AGC control…Thanks!

[Update: Jan 1, 2013] PL-880 owners living in urban areas with strong AM (MW) stations are hearing multiple images from those stations across the MW band, making it difficult for medium wave DXing.

But now, on to my favorite part of the spectrum…

Shortwave performance

PL660-PL880-SW7600GR

Of course, I’ve spent the bulk of my PL-880 listening time on the shortwaves…where I find the PL-880 a pleasure to operate.

Tecsun-PL880-SWLing-Post-0524Tuning

The PL-880 sports both broad tuning and fine tuning controls on the right side of the radio. They’re perfectly positioned to be operated with ease by the user’s thumb. They also protrude enough from the right side of the radio so that it can be tuned much like the tuning knob of the PL-660–from the top side of the control.

The keypad on the front of the PL-880 has a quality response/feel. Selecting a frequency is as easy as entering the number in kHz. No other button pushes are needed, much like the PL-660, and the Grundig G3. By pressing the “SW METER BAND” up/down controls, you can move through the broadcast bands with ease. Indeed, if you change the mode to SSB and use the same up/down arrows, the PL-880 will cycle through the amateur radio bands as well.  Nice touch, Tecsun!

Tuning increments are in very fine 10 Hz increments with absolutely no muting between frequencies…Brilliant.

The hidden sync lock feature

There was much speculation prior to the PL-800’s introduction as to whether it would have a built-in synchronous detector. After all, its predecessor, the PL-660, has a great sync lock that helps with selective fading and adjacent signal interference. I was very happy to discover that by pressing and holding the USB/LSB buttons, the user can activate an undocumented sync lock feature which is selectable on upper and lower side-bands.

After using the sync lock on a variety of strong/weak signals, I find that I’m not exactly wooed by it, however.  The PL-880’s sync detector is just not as good as the PL-660’s–not by a long shot. On weak stations, the PL-880 lock is feeble and wobbly. On strong stations, it makes the audio sound unnecessarily thin and sharp.

A sub-par sync lock is not a deal-killer for me, though.  Why? Because I get excellent results by simply using an SSB mode (USB/LSB) and zero-beating the AM carrier. It’s a trick well known in the SWLing world under many names–I call it ECR (exalted carrier reception)–click here for a previous article on the topic. This method rivals the PL-660’s sync lock under similar conditions. And as a bonus, the PL-880 bandwidths can be widened to 4 kHz, allowing near-AM fidelity in SSB.

How does the PL-880 compare with the PL-660, SW7600GR? 

A few days ago, I spent some time comparing the shortwave sensitivity and selectivity of the Tecsun PL-880, PL-660, and the Sony ICF-SW7600GR. Instead of shooting a video on my iPhone (which lacks a good mic), I used my newly-replaced Zoom H2N digital recorder with a direct, line-in connection.

I did my best to match the volume levels in the radios for a fair competition.  Note that while the Sony and the PL-880 have line-out jacks (a major plus, in my opinion), the PL-880’s line-out audio level is set way too high and overloaded the Zoom recorder; the FM line level can be adjusted, however.

AM Sensitivity

The first test was in AM, and I chose Radio Exterior de España on 9,605 kHz, which was moderately weak compared to other broadcasters on the 31 meter band. I recorded one minute clips. Halfway through the PL-660 and ICF-SW7600GR clips, I turned on the sync detector. On the PL-880, I simply turned on SSB, as I did not feel that its sync detector added to intelligibility.

Click on the radio name to download the MP3 of each clip, or simply listen via the embedded players below:

Tecsun PL-880

Tecsun PL-660

Sony ICF-SW7600GR

SSB Sensitivity

I then tuned all of the radios to 18,135 kHz, where ZD8UW (The Cambridge University Wireless Society) Ascension Island DXpedition was handling a pile-up.  You won’t hear stations calling ZD8UW, because they were working split and listening on 18,141 kHz. There is an adjacent SSB station, though, that you’ll hear on the side.

In this test, I had all the radios set to a narrow bandwidth. I had the PL-880 set to 3 kHz as it sounded similar to the others at that width. Since propagation conditions were changing,  I made two recordings of one minute’s duration of each radio.  I picked the version of the recording in which each radio experienced the same signal strength. Again,  you can click on the radio name to download the MP3 of each clip, or simply listen via the embedded players below:

Tecsun PL-880

Sony ICF-SW7600GR

The PL-880 is certainly sensitive on the shortwave bands, but when listening via headphones (as in this example), there’s sometimes a bit of splatter when the audio peaks. The PL-880 demonstrates great selectivity, as promised.  In the SSB example above, the PL-880’s 3 kHz filter successfully rejected the adjacent signal much more cleanly than the narrow filter on the PL-660 could.

PL-660 vs. PL-880: Which is the better radio?

In my tests, the Tecsun PL-660 does a fine job of holding its own against the PL-880, and is certainly the best bargain of the two at $100-$120 US. In general, I find the PL-660 to have an edge on the PL-880 in terms of sensitivity. While I prefer the audio characteristics of the PL-880’s internal speaker compared to that of the PL-660, vocals seem to pop out of the noise better with the PL-660.

But comparing these two radios in terms of sensitivity is problematic, as it’s not an “apples-to-apples” comparison. In the examples above, I tried to keep the playing field level by leaving the PL-880 on one bandwidth setting and not using the hidden DNR feature (which seems to alter the bandwidth and lower the noise floor). It’s certainly possible some users may be able to tweak the PL-880 to give it an edge on the PL-660 in similar conditions.

Whether or not you should buy the PL-660 or the more expensive PL-880 will clearly depend upon your listening goals. If it’s to pull out voices from the static, for station ID and weak signal DXing, the PL-660 is your radio. If you want armchair listening of shortwave broadcasts with very low listening fatigue, go ahead and splurge for the PL-880. If you want a simple, straightforward portable, the PL-660 is your best option. If you like to tinker with settings, and enjoy all a radio’s bells and whistles–including tracking down hidden ones!–the PL-880 is your radio.

If your goal is to listen to SSB broadcasts (pirate radio, utility stations, ham radio traffic, so forth) both radios will do a fine job, but the PL-880 is more versatile and, again, has better selectivity.

Frankly, I will keep both radios in my listening arsenal. Which will I turn to the most? While I love the PL-660, I’m a sucker for the more dynamic, rich audio of the PL-880. To me, any difference in sensitivity is negligible.

Summary

Every radio has its pros and cons, of course. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Following is the list I formed over the time I’ve been evaluating the Tecsun PL-880:

Pros

  • Excellent ergonomics
    • most functions are either available at the press of button–or by pressing and holding a button for three seconds
    • tuning options include a dedicated fine-tuning control
    • buttons have a sturdy, tactile feel and response
  • Excellent sensitivity and selectivity
  • Wide array of filter options in both AM/SSB–more than on any sub-$200 portable on the market
  • Absolutely no muting between frequencies, even while using a .5 kHz filter in SSB
  • Using SSB ECR is more effective than synchronous detector (see con)
  • Sturdy carrying case has dedicated pocket for English operation manual
  • Single supplied rechargeable battery delivers very long life (see con)

Cons

  • Update: Older firmware versions lack features of newer models
  • Two-second delay when changing modes (AM/SSB/AM sync)
  • Some audio splatter on peaks in weak signal DX
  • Quirky characteristics:
    • hidden features (see list at review’s end), some of which have major relevance in operation, such as changing the muting threshold; Tecsun, why hide these?
    • unexplained occasional changes in bandwidth while tuning in SSB
  • Sync detector delivers mediocre performance and substantially reduced audio fidelity (see pro)
  • AM (medium wave) prone to imaging if strong AM broadcasters are nearby
  • Supplied rechargeable battery is not as common as AA batteries (see pro)
  • Supplied battery charger is a bit noisy on medium wave and shortwave if listening while charging. (Not a problem for me, as I’m a batteries-only listener.)

All in all, I really like the PL-880. It’s a quirky little rig that boasts more features than any other portable I’ve ever used (save the Eton E1). It’s sensitive, selective, has silky-smooth tuning and robust audio…but it’s not perfect. Many of the cons listed above could be fixed with firmware updates…ones which I hope users can make at home as opposed to needing to buy a newly-updated radio.

And, Tecsun, I hope you add those hidden features to future operation manuals. We’re keeping track of them here, and on the Yahoo PL-880 group, but some recipients may never realize the muting threshold, for example, can be adjusted. Tecsun, if you feel like these features aren’t ready for production, simply label them as beta or experimental features, and go for it anyway.

With all of its features and functions, hidden or not, I’ve found the PL-880 to be a challenging, but thoroughly enjoyable, portable to evaluate. Indeed, I’m still not done yet:  I plan to take my new PL-880 traveling in the future. So, stay tuned:  there’s more to come!

[IMPORTANT UPDATE Dec 14, 2013: Many units purchased at Amazon.com (via Kaito Electronics) have an older firmware version and users report problems and lack of features/functionality. Many have even returned their radios for a refund. At this point, I would exercise caution when making a purchase; you might even wait until Tecsun has either removed the older firmware units from the market or given its users a way to make updates from home.  If you want to purchase a PL-880 soon, I can only recommend buying from the same company I did, Anon-Co–see info below. I would verify with them that your unit has the latest firmware.]

Where to buy the PL-880

The PL-880 is only available from a few retailers thus far–most of whom are on eBay, some on Amazon. I purchase all Tecsun products from Anon-Co–I’m sure there are other qualified sellers on eBay, but Anon-Co has always provided me with excellent and responsive customer service, so I can recommend the company. My PL-880 was shipped by Anon-Co and received in only three days. Kaito Electronics, a US-based distributor, also sells the PL-880 on Amazon.com. The price on the PL-880 has been fluctuating over time, but seems to hover between $150-$180 US:

SWLing.com’s 2013 Holiday Shortwave and Radio Gift Guide

gift-wrapOne of the most popular posts on the SWLing Post each year is the annual Holiday Radio Gift Guide. I started this annual post in 2010 when I realized that it would be easier than answering an in-box full of individual emails from people seeking the perfect shortwave radio for their friend or loved one.

In the following, you’ll find a handful of select radios I recommend for the 2013-2014 gift-giving season. I’ve arranged this selection by price, starting with the most affordable.

For the benefit of those with less radio experience, this quick guide is basic, non-technical, and to the point. For more comprehensive reviews, please consult our Radio Reviews page.

Updated for the 2013-14 holiday season on 08 December 2013.

Simple, affordable and portable

ShouYu SY-X5 ($29)

You can’t buy a lot for $30 US these days, but I’m here to tell you that you can buy a unique, portable AM/FM/shortwave radio with a built-in MP3 player called the ShouYu SY-X5.  I made a full review of the SY-X5 earlier this year; in short, it surprised me. While this little radio’s receiver can’t compare to the others on this page performance-wise, it is still very respectable. The MP3 capability is worth the price. You can load a microSD card full of your favorite music (or shortwave radio recordings) for days of listening!

Indeed, the audio from the built-in speaker is superb for a radio this size. Th SY-X5 can be powered from multiple sources (a rechargeable built-in battery pack, AA batteries, or via USB power cable).

Since the ShouYu SY-X5 is only available from eBay sellers in Hong Kong, you need to allow at least two or three weeks shipment time from the seller. You might ask if they offer an expedited option.

Click here to search eBay for the ShouYu SY-X5.

Other considerations include the Degen DE32 (review here) or Degen DE321 (review here). Note that the Degen DE321 lacks an MP3 player.

Self-Powered Shortwave Goodness

The Tecsun Green 88

Tecsun Green 88

In each issue of the holiday guide, I like to feature at least one self-powered radio.  Why? Because if you’re ever been left in the dark due to a natural disaster or extended power outage, these radios become invaluable.

The Tecsun Green 88 is not only self-powered, but quite a capable little analog shortwave radio.  It has a nested fine tuning control on the tuning knob, an easy to read display and will give you about 40 minutes of listening time (at moderate volume levels) from two minutes of cranking. The LED lamp on the front makes an excellent flashlight and reading lamp. Again, to my knowledge, this radio is only available from sellers in Hong Kong on eBay, so allow extra shipping time.

Some other self-powered radio options you might consider are the Eton Rover and the Eton FRX2, though note that they both have NOAA weather radio channels instead of shortwave. A very useful feature, though, for weathering winter storms.

Portable & powerful shortwave receivers

The Tecsun PL-660

The Tecsun PL-660 ($100-110 US)

With the introduction of the new Tecsun PL-880 this year, retailers have dropped the price of the PL-660; you can now find them between $100-110 US.

The PL-660 is an all-around excellent receiver with great sensitivity, selectivity and all of the features to please a casual listener or the experienced DXer. For a full-featured radio, the operation is so simple an owner’s manual is barely needed. The PL-660 covers the entire shortwave radio spectrum, LW, AM (medium wave), FM and even has an AIR band (to monitor aircraft communications).

[Update: Unfortunately, after reviewing the PL-880 favorably, I have discovered that many units–especially those purchased through Amazon.com–have an older firmware version and lack some functionality I would consider very important. I now suggest buyers wait until Tecsun has corrected this–sometime well after the holiday season.]

At time of posting, the Tecsun PL-880 has only been on the market for about a week. It is the newest flagship portable radio from Tecsun. I have been reviewing this radio for several days and find it to be an excellent choice, if your budget allows. (Indeed, reviewing this radio had lead to a late delivery of the Annual Gift Guide!)

If you would like to see and hear the PL-880 in action, simply click on this link and explore the numerous posts and comments.

In short: it’s a great radio with superb audio from the built-in speaker. It’s also designed to make the amateur radio operator happy as it has an array of filter selections for the ham bands. In my experience, the selectivity and sensitivity are on par with the PL-660 (mentioned above).  Click here to read a full review of the PL-880.

The PL-880 is only available from a few retailers so far–most of whom are on eBay. Again, I purchase all Tecsun products from Anon-Co–I’m sure there are other qualified sellers on eBay, but Anon-Co provides excellent customer service. My PL-880 was shipped by Anon-Co and received in 3 days!:

Tabletop Performance

The CommRadio CR-1 is sure to please even the most discriminating radio listener in your life.

The CommRadio CR-1 is sure to please even the most discriminating radio listener in your life.

CommRadio CR-1 ($600 US)

The CommRadio CR-1 was introduced early this year and began shipping in the Spring. While you can read my full review of the CR-1 by clicking here, in a nutshell, it’s a brilliant little receiver! It wooed me from the moment I first saw it.

The CR-1 is made in Colorado, USA by CommRadio, a company well-versed in radio avionics. It’s thoughtfully engineered, relatively small (über portable), and meets all of my performance needs. It’s also a fun little radio and very easy to operate.  The CR-1 can be updated by the user via a USB cable and free PC software. Many of the updates include minor tweaks requested by users and even new features.

Only one catch: CommRadio has sold out of their stock for the holiday season. They’re offering a $25 coupon (see below) if you order and don’t mind an early January delivery time. However, call Universal Radio as they had radios in stock at time of this posting.

Purchase the CommRadio CR-1 from:

  • CommRadio (until December 31, 2013 use the coupon code CR12014 at check out to receive $25 off the price) or
  • Universal Radio who may have them in stock to ship

Other tabletop radios to consider are the Alinco DX-R8 and the Icom R-75.

Looking for an accessory?

UniversalRadioIn addition to the radios above, there are many antennas, accessories, books and used gear that you might consider. I would encourage you to contact Universal Radio and speak with one of their staff to seek suggestions. I mention Universal Radio frequently, because they are one of the only remaining true shortwave radio retailers in the US. If you live in Canada, you might also consider Durham Radio, in the UK, Waters & Stanton. (Readers: if you have suggestions of radio retailers in your country, please comment on this post.)
