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.
