Many thanks to SWLing Post reader, Bill, who writes:

Maybe you already know this, but I only recently discovered the Tecsun PL-880 rechargeable battery is available on Amazon for $9.99 and can qualify for Prime free shipping. I bought one and it seems to work great. There are other battery models on Amazon that may work, but many had comments about inconsistent quality, various countries of origin and even various sizes! I decided to go with this one branded as Tecsun to play it safe and am happy. Just an FYI to your readers.

Thanks, Bill! I have two PL-880 batteries and they continue to do a fine job running the PL-880. They are over two years old now (hard to believe–!), so I’ll keep Amazon in mind. Note that Universal Radio also has the replacement battery for $9.95 (though no free shipping).

Simple modification to disable soft mute on the Tecsun PL-210

Many thanks to SWLing reader, Mini, who wites:

I am Japanese short wave listener.

I found the method that disable soft-mute of TECSUN PL-210.
And, I posted the article in my blog.

Please forgive me that may be difficult for you to understand the content.

Thanks mini

Thank you, Mini! I don’t have the PL-210, but if I did I would certainly disable the soft mute as I find it very distracting during routine band scans.

The CountyComm GP5/SSB: my go-to shortwave radio for hiking

CountyComm GP5/SSB while hiking

My two hiking companions: the CountyComm GP5/SSB and Hazel the dog.

Posting the Blinq deal a few moments ago reminded me that my favorite shortwave radio to use while hiking/walking is the CountyComm GP5/SSB.

I have CountyComm’s custom GP5 case which I clip to my belt or backpack. While hiking, I find it handy to open the case from the top, pull the radio out and operate/tune it with only one hand. Indeed, the vertical form factor of the GP5/SSB is ergonomically-ideal; I can control almost all of the radio functions without having to use two hands. A huge bonus while hiking on uneven terrain!

Typically, when I start a hike, I enable an EMT scan and within a minute or so, the GP5/SSB populates temporary memory positions with all of the signals it can easily receive. When you’re in the middle of the woods–far from sources of radio interference–you’ll be amazed by what you can hear.

Of course, with the antenna fully extended, one does have to watch out for low-hanging branches, etc.

Since the telescoping antenna doesn’t swivel, it’s much easier to hold the radio in a way that the antenna points forward while you hike (bonus: it’ll catch all of the spider webs across the trail before your face does!).

GP5SSB-MW-Antenna

So far, I’ve never used the external mediumwave ferrite bar antenna while hiking–I worry that I could drop the radio and damage either the antenna or the 1/8″ antenna jack.

I typically listen to the GP5 with headphones unless I’m walking a trail during the time of year when black bears are active (in which case the speaker helps alert bears that I’m in the neighborhood).

GP5SSB-Front

Of course, there are a few other radio models with an identical vertical form-factor–most notably, the:

Guest Post: Jerry’s Mediumwave DXing Powerhouse Mini FSL Antenna

Many thanks to SWLing Post contributor, Jerry Popiel, for the following guest post:

A MW DXing Powerhouse Mini FSL Antenna

by Jerry Popiel

In late February 2016 I completed construction of a modified version of Gary DeBock’s excellent 3 inch Mini FSL design (click here to view).

This new antenna is nothing short of a AM DXing powerhouse with unbelievable sensitivity for receiving stations across the entire AM Bandwidth both day and night. The tuning of stations is razor sharp and it has stunning nulling qualities. Consultation assistance was provided from DXing experts Steve Ratzlaff and Gary DeBock on the project.

Construction Details:

The Antenna was constructed using 9 – 100 mm Ferrite Bars wound on a 2.75 inch diameter x 4 inch styrofoam cake dummy form custom made by in Vancouver, B.C. Canada – (stacy@scoop-n-save.com) for $3.50 plus shipping.

The Coil wire consisted of 38 turns of high gain 660/46 Litz Wire. (Note: As can be seen 38 turns of the thicker Litz Wire left only 5/8” of room on each side of the Styrofoam Form to wire wrap the coil to the ruler frame. A longer Form ie 5” long would work much better for this build).

The insulation spacer used was 2 layers of 1/8 inch Aerotape self adhesive tape which also helped hold the 100 mm Ferrite Bars onto the Styrofoam Coil Form. Inductance measured 356 uH using a DM 4070 Meter which is well within the requirement of over 300 uH for AM Band Reception.

Because of the extra thickness of high gain 660/46 Litz Wire which is a bit too big to solder to the inside terminals of the Tecsun PL-380 Radio, a 2 Position Terminal Block was superglued to the outside of the Ruler Frame to act as an interface connection point.

Testing Results:

Both daytime and evening AM station captures have been spectacular. Stations as far away as KKOB / 770 kHz Alberquerque, New Mexico 1130 Miles from here in Winnipeg, Manitoba, Canada have been received. Country music station WSM / 650 kHz in Nashville, Tennessee 1082 miles distant is a daily evening pickup.

Two Stations Received At 600 kHz 90 Degrees apart at the same time:

The amazing Nulling and Razor Sharp Tuning quality of this FSL was demonstrated when 2 stations at 600 kHz were received at the same time by rotating the Radio with attached FSL 90 degrees. In the North / South direction Station KSJB / Jamestown, North Dakota (219 miles distant) was received with a strong signal strength of 50 / 23. Then by rotating the Radio 90 degrees to the East / West direction Saskatoon, Saskatchewan station CJWW (442 miles distance) was captured with a similar strong signal strength of 44 / 24.

Daytime Reception of 600 Watt Station 137 Miles Distant:

A major daily AM reception capture during the afternoon illustrating the amazing sensitivity of this antenna is 600 Watt station KKXL Sports Radio 1440 kHz (137 miles).

All Indoor Reception – For Now!

Due to winter conditions here in Winnipeg, all of the amazing station reception captures in this report were done inside the House facing towards the South window. Fortunately the red ruler platform sides can he used as handles when pointing the radio in the direction of best reception. Exciting times are ahead to see how well this mini 3” FSL will perform outdoors for likely even better AM DXing.

Summarizing:

The design of this new FSL Antenna attached to the Tecsun PL-380 Ultralite radio by Gary DeBock is a major breakthrough in AM DXing since the Radio is attached to the FSL. This new FSL Antenna needs to be constructed to be really appreciated. The application described here requires a bit more skill to construct and is also heavier than the original construction – but at least it is portable. For beginners Gary’s original 3” FSL Heathkit Design is highly recommended and can be reviewed in his You Tube Video posted at: https://www.youtube.com/watch?v=VY9u8MReGjk

Thank you, Jerry! It’s amazing what performance you and Gary DeBock have gotten out of these homebrew FSL antennas! Thank you so much for taking the time to share your construction details and performance notes!

Tecsun PL-606: Tapping into the IF?

TecsunPL-606SWLing Post reader, Lee, writes:

I just wondered if you have ever seen any information about how to tap the I.F of the Tecsun 606 by any chance? I want yo use it for DRM but cannot find any info .
Love the website !

I have not seen info on tapping into the IF of any of the recent Tecsun portables. Can someone help Lee?  I would be very curious how to do this myself.
