The user interface dictates one study the manual carefully and retain it for future reference (complicated radios have a lot of little multifunction buttons and not much user interface to communicate function). The buttons work pretty good, and the display is pretty easy to read even for older eyes (includes an amber backlight). The integrated battery charger works great. The radio came with NiMH AA cells, which worked fine too, but at some point I swapped in my old reliable Sanyo/Panasonic Eneloop cells.
The longer accessory antenna improves distant signal reception as does the also included wire antenna. The lanyard works great and the speaker is loud enough to hear radio while showering. The plastic kickstand is a little flimsy, be careful as you can actually damage it by pressing buttons with a bit too much force in the reclined position. Recommend always grasp rear of radio as you press buttons if you want kickstand to last. BTW Tecsun doesn't sell a replacement kickstand, but they should since it's a simple 10 cent piece of plastic subject to failure under normal use.
Tecsun, I would love to own a version of this radio with 128GB SD memory card, bluetooth 4 and PROPER mp3 play/record capabilities.
The speaker sound is pretty good for it's size. Shortwave reception is pretty good. The antenna extension helps the radio bring in more stations on shortwave and fm. A great radio for emergencies, camping and traveling. This radio will out perform others in it's class. I ran a test to see how many stations I could receive; 28 am and 58 fm. For the price, a great well rounded radio.
It works beautifully with Sanyo Eneloop Ni-Metal Hydride rechargeable batteries, using the in-radio charging circuit. Just hook up the charging cable, if you have one, to a wall cube, and the radio will reliably charge the batteries and shut off the charging, without you having to remove them. While my first radio came with a charging cable, the second did not. If you are stuck without a charging cable, its easy to remove the batteries and use an external charger.
The manual is brief...and challenging, but a more detailed manual is available for downloading
(but some elements are in chinese). Many of the big players on SW have ceased operations, but
there are still some stations of interest. The Tecsun ETM feature works flawlessly. The speaker is small,
so don't expect much fidelity, but this is an outstanding portable. For under 50 bucks...it is a steal.
Earlier reviews cover more of the features. Again, if you DX...you need this radio.
As for the radio, I wish I'd had this little wonder back then. It's truly tiny yet quite capable. The manual is, as others have written, terrible. It isn't that hard to figure out the radio's features with a bit of tinkering, but I'm past the point in my life where I can let poor documentation and bad user interface design go unmentioned.
For the price, you'd be hard pressed to find a better portable for listening to the AM and FM bands. But don't expect too much from shortwave. I'm afraid that, like newspapers, this form of communication is on its deathbed.
I have the backstand on this and similar TECSUN radios break on me, usually after 6 months or so.
There is a solution to this problem: Amazon sells both "silver' and 'black' business card holders.
Ideal for this radio as "stand".
Look for "Buddy Products Mesh Business Card Holder, 3.1 x 1.6 x 3.9 Inches, Black (ZD021-4)"
I have owned this radio for a few months.

1. VERY good FM, nothing more to say.
In fact the PL-606 beats even my "KAITO/ DEGEN 1103" (the 'gold standard' among radio aficionados).
2. Really good AM, important for us 'news and talk radio' junkies.
The selectable bandwidth (from 6 down to 1kHz) unique. REALLY valuable at night.
3. For the international traveler (UK, France, Eastern Block countries), the PL-606 LW capability
is unique. The long ferrite rod (which makes its AM good) should also boost its LW performance.
4. Love the ETM tuning (which leaves stations that you have stored for local use "untouched").
REALLY useful feature to have TWO sets of stored frequencies, one "permanent" for home,
i.e. no re-setting required when you return from travel. The other for when you arrive at a
new location. All of this one-touch button "automatic". Done in two or three minutes.
It really picks up and stores ALL useful stations.
5. 1000 mAh NiMH rechargeable from a USB port device using an internal charger:
NICE feature! Charging takes a full night. The battery consumption is very low. (Note, my PL-606
came with two 1000 mAh AAs. I assume this is, so that a USB port/ outlet can fully charge
the two AAs in less than 10 hours.)
6. NICE also that there are only TWO AA batteries required. (Some external chargers will take only
TWO AAs, in series.)

1. On my PL-606 the station selector has developed a tendency to skip, repeat and jump back on the stored
frequencies. Not clear why. Is this possibly a 'beginning failure mode'?
2. The VOLUME control is in digital steps. On FM it is never right: "6" not loud enough. "7" TOO loud. Wish they had a "6.5" ..
3. TUNING -- I miss a DIRECT frequency input.
-- AM in the US: the frequency steps are NOT "10kHz" - i.e. it does NOT jump from one North America station to the next. That would have been a desirable feature. Instead you must fiddle with the station selector until you come to an occupied frequency.
4. Speaker -- tinny. But who would complain given the PL-606's size!
5. LW -- The manual does NOT explain how to switch LW on; press AM and FM simultaneously.
by the size I thought it would be bigger.I found out bigger
is not always mean better.I love the fitures ETM it is easy to
set up and work with the sound is great .I mean you can't really
ask for more .I love my PL-606 I feel I got my moneys worth.

The Short wave reception is disappointing. In Les Cayes, Haiti the only English language news I could get was from China CRI. Even in Rhode Island, I could not get VOA or BBC clearly even with the long wire antenna.
The directions and button combinations were difficult to learn.
I wish it had a numeric keyboard so I could key in a known station.
AM is not quite as good as the 390, which makes sense because of the smaller ferrite antenna and there is no direct frequency keys, but the FM is still incredible and it's small size makes it the ideal pocket radio.
One thing I've noticed on the Tecsuns...there is absolutely no spillover of adjacent FM signals when you are in big cities. Every pocket radio I've owned, including the highly regarded Sangeans 120 and 210 have that problem when traveling through cities..the spillover of FM signals and sometimes not being able to pick up a signal at all..but not the Tecsun models. In Manhattan last week I was picking up Trenton,NJ's 101.5, Long island's 98.3 and Connecticut's 96.7 and 107.9 with amazing clarity. As I have stated, the FM reception is the best I have ever heard on a portable radio.
Once in a while the radio will freeze up,but a little button pushing will alleviate that.
The 606 is a little bigger than the two Sangean portables I mentioned, but this is my pocket portable from now on. At $50 this is quite a bargain.
using ETM found over 32 radio stations in my area and also found the semi locals than my other tuners. This is the ideal radio for people who are in campus trying to receive those part 15 and college radio broadcasters in the area and it can receive 64 MHz to 108 MHz which is good for receiving 72 to 73 MHz transmissions with no problems. The good thing about radio too is that it has a external FM antenna and shortwave antenna input jack, but it would have been nice for it to have 2 jacks, 1 for AM/LW and the second for FM/SW or some antenna switch.
For the AM band, the radio receives alot of AM radio stations with the ferrite bar antenna. It's best that you couple a loop antenna for more signals to be received. The bandwidth selector switch is a great feature
it can receive signals that you could not receive before. The LW bands, which are my favorite, does not do too well below 280 kHz, but works good above 300 kHz to 520 kHz. I received 1 beacon on there which is Beacon OR on 329 kHz, but could not receive Beacon CLB on 216 kHz. I did receive the other beacons using the KA-35 loop antenna, but I know I will receive more outside. The thing that really bothers me is that it does not have 513 kHz to 519 kHz coverage Why?
The Shortwave Bands work very well with the wire antenna. It can receive many stations using the ATS or ETM
during the afternoon and evening. The whip extender does not do anything except for FM, but the long wire works better. It can cover frequencies from 2.3 MHz to 21 MHz, but it cannot find signals in the odd ball frequencies while scanning using ATS or ETM. The bandwidth switch works well on the short wave bands. It cannot receive SSB which this radio is good for AM only transmissions unless you use a external BFO circuit.
The radio is a good piece of equipment, but it is a good FM DXer's radio and ok AM/LW/Shortwave receiver.
I have been a shortwave listener since 1964. It's fascinating to me that radio signals can travel around the globe and I hear programs from countries I may never visit. The PL-606 is, by far, one of the best-designed portables I own. I like the choice to use presets or free tuning. AM reception is quite good - I'm able to hear AM 740 in Toronto - I live 60 miles north of Philadelphia) as good as my more expensive radios. The adjustable bandwidth is so nice - narrow for far close frequency stations, wide for other. Since I listen to the radio to fall asleep, the sleep timer - being adjustable - allows me to set it to a number of minutes before it will turn off. I even like the light up dial - it only shows for a few seconds while tuning, then shuts off.
Shortwave is amazingly good with the whip antenna. A better antenna is preferable, especially during the daylight hours, but this little box pulls in enough to keep me DX'ing for hours. Attaching the included long wire or whip extension helps.
The size is perfect - I can put this in a coat pocket. Sound is good, battery life seems fine, and, after a few minutes of reading the included manual, I was up and running.
An exceptional value for under $50.
However, the dimensions listed: (7.4 x 1.1 x 3.2 inches) is incorrect. I measure 5 x .9 x 3.2 inches. For a moment I thought they sent me a different model, but no, it's the PL-606. Small is good for travel, but not so good for sound.
I was actually hoping the radio was larger with a larger speaker for deeper sound, but you can forget about it. The sound quality is as tinny as they come as the speaker area is less than 2 inches. However, if you attach a big speaker, such as the bass speaker from a discarded 3.1 channel computer speaker system, you will get a wonderful, rich sound, comparable to those $100+ AM-FM digital table radios. You may need to be handy with a soldering iron and know which wires go to which terminal however. The audio power output from this little radio is much better than other devices I have, like my 370M Gateway Laptop, which can barely drive the same speaker.
No batteries included, and no AC power source. However, the mini USB port accepts cables from your computer, and you may already have a AC power source from another device. I had one from a Garmin GPS that works.
Station reception for FM/SW depends on if you use the included wire plug-in antenna or not, but even without it, it picks up many stations. MW isn't too good until you try it at night or live in a metropolitan area.
The radio came very quick...much quicker than any other product I ordered from Amazon. Maybe because it was so light and fit in a padded envelope.
It's very small -- smaller than my hand and fits in any pocket. It's sensitive enough to hear *almost* anything my venerable Sony IC-2010 can hear. There's even a clip-on telescoping antenna extension, which I find clunky. I suspect it would overload here in Minnesota with a long-wire antenna (don't have one up yet), but this is a *portable*. I'm willing to take this places I wouldn't take the Sony. $50 isn't "disposable," but if I lost it I wouldn't be heartbroken.
Tuning is intuitive enough. I can't expect a direct frequency keypad in a radio of this class. The ETM feature, where it scans the bands for strong stations and stores them, is actually quite convenient. In ETM mode the tuning dial moves between stored stations, or you can just manually have it move 1KHz at a time. My only gripe with manual tuning is that it's difficult to get it rapidly into fast tuning mode (5KHz per step) -- there seems to be some "feel" trick that I'm not good at. I'd like it more if there was a button for this. I've barely used the user memory mode yet so I can't comment. Though not documented in the sparse manual, this radio *does* cover LW starting at 150Khz. Hit "MW," wait for it to come up, and hit "MW" again. There's not much LW to listen to in the States, so I don't know how well it performs.
Selectivity is excellent, as I'd expect in a DSP radio. Default is 3KHz, and the "BW" switch rotates through 2Khz, 1KHz, and up to 6Khz. The skirts are easily steep enough for an AM/SW broadcast environment (9-10Khz spacing).
It does NOT do sideband or CW -- no BFO. Again, this would be a bit much to ask for it to be implemented well in a $50 portable.
Audio quality is adequate through the speaker -- poor bass but that's what I want for intelligibility in an AM station. FM stereo sounds great with headphones.
I've only had it for a couple of weeks, so I can't comment on durability. One reviewer noted that the tuning and volume encoders seemed to wear out after just a couple of months. If that happens, I'll amend my rating, but for now I'm delighted.
DECEMBER 2013 UPDATE -- Three things that aren't great:
1) The whip antenna may be a bit weak. I managed to pull mine in two, separating it at the base just below the pivot. I'll take the blame for that. Though it snaps back in, it's been weakened and now regularly pulls out. It looks easy enough to replace if you can find one the right size -- I've ordered one from an eBayer in Thailand.
2) Now that I have a long wire antenna up, it really does overload badly. I'm in a high signal environment here in St. Paul, Minnesota, so this is not surprising. It's mostly a problem with KSTP-AM at 1500 kHz. The radio is meant to be a portable, however, and best used with the whip.
3) Lastly, the only "real" annoyance with this thing that's not my own fault: the volume control is not smooth analog; it's an encoder that steps up and down. One step goes from too soft to too loud when using ear buds or cheap earphones. To get around this I have to use earphones with an independent volume control, but they're big and clumsy.
BUT I'm nitpicking. Given what this radio does for $50, I'm still giving it 5 stars. It's an entertainment device, not a serious communications receiver, and it does entertain.
In a head to head comparison to a Grundig traveler radio with short wave capacity and a CC Crane, it performs as well without the cost. the only change I would make to this radio would be to use a 90 degree plug for the 15 meter to reduce the profile of the radio.
This is a good radio worth the money paid.
Pros: I like the smaller size, great quality, 3 antennas provided, Good features for SW, picks up good SW frequency range.
Cons: Can be somewhat complicated w/ all the features and none of the abbreviations intuitive. No power cord included.
Like I said, just bought it, used it a couple of times, love it.
