Video: How to calibrate the Tecsun PL-660 frequency offset

Many thanks to SWLing Post contributor, Mike Mander, who writes:

I’ve recently really been enjoying swling.com. Thanks for having such a great resource online with shortwave radio and hardware reviews, tips and more! I started listening to shortwave on an old Philips portable receiver back in the late 70’s as a teenager. Recently, after decades of not listening to shortwave, I decided to buy an Eton ‘Grundig Edition’ Satellit radio and in no time at all, I had also acquired a C.Crane Skywave SSB and now, within the last week, a Tecsun PL-660.

[…]I thought I’d record a video showing how one can calibrate AM, FM, SW wide-bandwidth as well as SW narrow-bandwidth independently, and how to reset those calibrations back to factory default. I have not heard it mentioned anywhere that one can calibrate both wide and narrow bandwidth SW modes independently.

Online, I have read about many people being disappointed in their PL-660’s wide-bandwidth frequency calibration, where often being on-station results in the frequency being up to 5 kHz too low, and it seems many simply return their radios as defective, not realizing how easy it is to recalibrate. This is the first “instructional” video of this sort that I’ve ever posted online, so you’ll have to pardon if I am perhaps not explaining things clearly enough:

Excellent video, Mike! You’ve done a fine job making the explanation clear and easy to follow. Thank you for sharing!

Comparing the XHDATA D-808, Digitech AR-1780 and Tecun PL-660 on shortwave

On Friday, I managed to set aside an hour to finally do a video comparison of the Digitech AR-1780 and the new XHDATA D-808.

I placed a table in my driveway, far away from any source of RFI, and set up the radios in identical configurations: same orientation, antennas fully-extended, same AM bandwidth (4.0 kHz), same audio levels, etc. For good measure, I also included the venerable Tecsun PL-660 in the mix.

This was still daytime listening, so all of the stations were from 31 meters and up.

Apologies in advance: somehow the cord from my monitoring headphones is in the shot on some of these videos! I’m still getting used to the new Zoom Q2n video camera:

WRMI 9,455 kHz

WWV 15 MHz

Deutsche Welle 15,200 kHz

Afia Darfur 9,825 kHz

I should add that QSB was slow and deep on Friday. Twice I had to re-shoot videos because the station simply faded into oblivion.

I plan to do a few more comparisons with the XHDATA D-808 and Digitech AR-1780 soon as I’m very curious how SSB reception may differ.

Please comment with your observations. Which radio did you prefer? I’ll hold my comments for now.

Tecsun PL-880 hidden feature/hack: 1 kHz bandwidth on shortwave

[Note: This procedure was updated and simplified by Guillermo on 22 December 2017]

Many thanks to SWLing Post contributor, Guillermo, who writes:

I own the PL-880 and just discovered a new feature : a 1.0 kHz bandwidth mode on shortwave (SW only not in MW).

The procedure to get it is as follows:

  1. Turn on the radio and tune any frecuency on SW . There is no need to connect or disconnect an external antenna and turn on or off the radio during this procedure.
  2. Be sure that on SW the 4 button feature(press 4 for about 2 seconds) is ON and 9 button feature(press 9 for about 2 seconds) indicates a value of 13 or more and not less than 10.
  3. Then turn OFF 4 button feature and then ON again . Press BW button and see the 1.0khz new BW on the screen. Now you can use it permanently on SW and ALSO on MW , UNTIL you press BW button again .

Well, I hope you understand this description–if not please let me know, and tell me if it works on your unit, or it is just works on mine.

Thank you, Guillermo! I see where this is somewhat of a fragile adjustment in that a number of actions could change the bandwidth back to a previous setting, but nonetheless is quite a fascinating hack/hidden feature! Thank you and I’ll add this to our list of PL-880 hidden features.

Post readers: please comment if you can successfully enable the 1.0 kHz bandwidth on your unit.  Please comment with your radio’s manufacture or purchase date if possible.

Tecsun PL-660: A simple hack to scan the air band

Many thanks to SWLing Post contributor, Bruce F, who writes:

HI Thomas, I thought I would put this idea out to your site – in case it isn’t already there. It’s a brilliant solution to the apparent lack of a working Air Band scan function on the Tecsun PL-660.  Note – I did not come up with this idea, but came across it in a Yahoo group.

It IS possible to scan the Air Band on the PL660, as long as you have picked out WHICH Air Band frequencies are in use in your area. There are websites which list these frequencies for each airport:

Here’s how to set up the PL-660:

  1. Pick an empty page in the Memory.
  2. Put in a shortwave frequency in the first empty space; the “00” slot.
  3. Then fill in the succeeding spaces on that page with the Air Band frequencies you’ve chosen.
  4. Now go back to the “00” slot and hold down the scan button.

Works on my set!

What a cool trick!  I’ve lent my PL-660 to a friend, but as soon as I get it back, I’ll also try this trick by setting up a page dedicated to my local aviation frequencies!

Thanks, Bruce!

For Sale: My Tecsun PL-600

>>>>>UPDATE: This radio has been sold!  Thanks for your interest!<<<<<

I’m in the process of thinning the herd around here at the SWLing Post HQ! I have dozens of portable radios that I rarely use–many I keep solely for review comparisons and benchmarking.

I’ve always loved the PL-600, but I rarely turn it on these days. I have the PL-660, PL-680, PL-880 and a number of other similar portables for review comparisons.

I used to lug this receiver around quite a bit–somewhere in my travels I scratched the display a bit.

It doesn’t hinder the ability to read the display–not cracked, just scratched–but it’ll turn off someone looking for a perfect specimen for sure. Indeed I’m sure there are other light scratches to be found.

It comes with the original box, soft case, earphones, power supply and manual. Essentially, the full original package.

This unit, of course, works beautifully. In fact, I turned it on for the first time in a few months and check out what was on frequency! So–BONUS!–if you’re a spy, this might be your dream radio.

I want this to be a good deal for someone, so I’ll ship to the first person who offers $40 or more (not too much more, okay?). Free shipping via the USPS. Payment via PayPal.

If interested, just contact me via email.

>>>>>UPDATE: This radio has been sold!  Thanks for your interest!<<<<<

I’d prefer not to ship internationally as it often involves a headache and would incur additional costs which I can’t predict. 🙂 Thanks for understanding.

All I ask is that you put this little radio on the air!
