In the following video, I compare single side band reception between the Tecsun PL-880 and PL-660. On 80 meters, in SSB mode, you can hear that the PL-660 has a slightly lower noise floor than the PL-880. Note again, however, that I mistakenly had the tone control of the PL-880 set to “bass.” I’ll try to make another video later with the tone control set to the “treble” position.

In the following video, I have tuned both the Tecsun PL-880 and the PL-660 to a relatively local AM station (880 kHz). Note that I had the tone control switch set to “bass” on the PL-880 (it would have been better on “treble”):
For normal AM radio listening, I believe the PL-880 produces better audio fidelity than the PL-660. I will try to record a weak medium wave station this evening, if time allows.

In this video, I’ve tuned both the Tecsun PL-880 and PL-660 to All India Radio on 9,445 kHz (transmitted from Bengaluru, India, some 8,800 miles away).
Thanks to an image of a (prototype?) PL-880 keypad posted on the Tecsun PL-880 Yahoo Group–an excellent group you should join, by the way–I’ve discovered that if you press and hold the number 6 on the PL-880 keypad, it engages the hidden DNR function. I assume DNR is an acronym for “digital noise reduction.”
I engage the PL-880 DNR feature in this video and compare with the PL-660 audio. Again, apologies for quality as this was made using my iPhone.

Once again, I ventured out to my truck tailgate to make a few videos of the Tecsun PL-880. In this video, I’ve tuned the PL-880 and PL-660 to Deutsche Welle’s English language service on 9,800 kHz (transmitted from Kigali, Rwanda, some 7,600 miles away).
I made this video with my iPhone, so apologies for the low quality:
Note that when I first turn on the PL-660 it is in sync mode by accident. After changing the bandwidth on the PL-660, I then turn off sync.
I’ve noted that the PL-660’s sync detector locks better than that of the PL-880. However, using the PL-880’s SSB mode to zero-beat the AM carrier (see article on ECR), produces great (and stable) results.
Sensitivity-wise, these radios are quite similar. While I personally prefer the audio of the PL-880, the PL-660 makes vocals pop out of the noise a bit better.

The supplied Tecsun PL-880 charger/power supply (Click to enlarge)
I’ve had a lot of questions and comments about whether the Tecsun PL-880 is supplied with a power supply/battery charger. I purchased my PL-880 from from Anon-Co on eBay and they sent a charger along with the radio.
The charger was not in the actual PL-880 (OEM) box, but wrapped up inside Anon’s FedEx shipping package. I found it instantly.
I mention this because I’m not sure if other vendors are supplying a charger as well–perhaps other PL-880 owners can comment?
The charger has two ports where the supplied USB cable can be plugged in–both 5 VDC, but one rated at 1000mA and the other at 2400 mA. Either would work to power the PL-880 as it only requires 300 mA. For charging, I would use the 2400 mA port–though the 1000 mA port may work as well. You certainly can’t hurt the radio by using the higher mA port as the radio will only use the amount of amperage it requires.
I will also note that while I prefer portables having the more standard AA cells, the supplied PL-880 rechargeable battery (see below) has superb capacity. With all of the listening time I’ve been logging, I still haven’t needed to recharge it yet. I suspect its capacity is superior to that of most AA rechargeables.

While working outside today, I propped the PL-880 up on the tailgate of my truck and listened to some international broadcasters on shortwave. I then received a message from a reader asking if I would make a video of the PL-880 being tuned to CW (Morse Code).
I switched the PL-880 into SSB mode and quickly found a “pileup” of CW operators around 14,035 kHz.
In this video, I used the fine tuning control and the bandwidth selector to give you an idea how the PL-880 sounds in tight conditions. The bandwidth will narrow all the way to 500 Hz (.5 kHz)–a very respectable width for CW. While it doesn’t sounds as good as an amateur radio transceiver, it is certainly better than any other portable shortwave radio I own.
Also, about halfway through the video an operator begins tuning up in the middle of the CW pileup (terrible manners!); I used it as an opportunity for you to hear how smooth the PL-880’s 10 Hz steps sound as I move away from his signal.
You’ll also note that I press and hold the number 6 and the display flashes “OFF.” I believe this is a noise reduction feature, but will need a little more time to experiment.

I normally like to do in-line recordings for audio comparisons of radios, but my digital recorder is non-functional at the moment. This fact–coupled with a bit of reader peer pressure–prompted me to take a short video with my iPhone of the PL880 and PL660 in action. While this will not be a true representation of the PL-880’s audio, of course, it should serve as some point of comparison in terms of function.
In this (very basic) video, you can hear the difference between the PL-880 and PL-660 when both radios are coping with adjacent signal interference. In this case, I tuned to Radio Australia on 9580 kHz–typically a blow-torch signal here in eastern North America. I wanted to gauge how each radio coped with adjacent signal from China Radio International broadcasting out of Cuba on 9570 kHz, which can cause major adjacent signal problems, even though it’s a full 10 kHz below Radio Australia.
In this video, I tried to use both radios’ bandwidth controls and (upper side-band) sync lock to cope with the interference. Forgive the lack of tripod. Here you go:
