The Choyong WT2 Kickstarter Campaign: A Walkie-Talkie with Shortwave, Internet Radio, and Much More

One of our sponsors, Choyong Radio, has launched a new Kickstarter campaign for what they call “the next generation walkie-talkie.”

Click here to check it out.

According to the campaign specs, the WT2 combines:

Dual-Mode Communication:
- Analog 450 MHz band for classic two-way radio.
- Push-to-Talk over Cellular (PoC) via 4G/Wi-Fi for worldwide communication.
World-Class Reception:
- High-sensitivity FM and shortwave (SW) reception powered by the TEF6686 chip.
- Pulls in extremely weak signals most radios miss.
Global Radio Streaming:
- Access to 50,000+ internet radio stations in the palm of your hand.
- Built-in ChatGPT search — just ask it to “find a jazz station in New York” and it will.
Smart, Portable Design:
- 2500 mAh fast-charging battery.
- Brilliant high-resolution display.
- Sleek, modern styling built for both outdoor adventures and everyday carry.

Choyong’s vision: “This isn’t just for outdoor adventurers or radio enthusiasts—it’s for anyone who values staying connected and entertained.”

I’ll admit that Choyong has done an impressive job with the LC-90, packing a lot of features into one radio. I can see where this HT-sized unit would really appeal to those who enjoy traveling. Keep in mind, though, this is a crowdfunded campaign—so you’re investing in a product to help bring it to full production. Unlike many first-time campaigns, however, Choyong already has experience successfully taking products from design to market.

Greetings all SWLing Post community, Imaginary Stations have a couple of great programmes this week over those short waves. The first is on Saturday 13th September 2025 at 1100 hrs UTC on 6160 kHz and then again on Sunday 14th September 2025 at 0900/1300 hrs UTC on 6160 kHz and at 2000 UTC on 3975 kHz and 6160 kHz (via the services of Shortwave Gold) we bring you the first in the programmes called Skybird School of the Air.

The programme is aptly educational themed especially as the schools are back so do have that notepad at the ready as you don’t want to miss anything as there will be a multiple-choice quiz at the end of transmission*.

It’s all good natured though and there won’t be any weekend detentions if you get the odd answer wrong. The only qualification you need to listen to the transmission is to own a shortwave radio or access to an online SDR. If all goes well we will have a local school brass band in the studio for a rollicking version of “Schools Out” and a first year college student choir entertaining us with a song about the importance of algebra and how fun it can be*. Tune in and be prepared to learn something.

* All subject to availability of course.

On Wednesday 17th September 2025 via WRMI we have another Radio Ace episode. Thanks to all the listeners who emailed us wanting to hear the show return to the airwaves and keep them ears open to catch if the great DJ Flash Frisbone will appear or not.

For more information on all our shows, please write to us at [email protected] and check out our old shows at our Mixcloud page here.

Noise-Reduction Ideas via Hackaday & Electronics Unmessed

Many thanks to SWLing Post contributor Dennis Dura for sharing this excellent Hackaday feature: Quieting That Radio. If you’ve ever struggled to hear weak signals through modern RFI, this piece, featuring content from Electronics Unmessed, is well worth checking out. It explores the hidden interference SDR setups often face and offers simple, practical/inexpensive fixes—like adding a counterpoise or ferrite choke—that can make all the difference in pulling in those hard-to-hear stations. This is advice we’ve recommended in past articles, but it’s brilliant to see demonstrated improvement.

KBS World Radio – Then and Now

Many thanks to SWLing Post contributor Dan Greenall, who writes:

Back in the 1980’s, KBS World Radio was known as Radio Korea, and they could be heard quite well at times here in eastern North America. Even with modest receiving equipment, their familiar interval signal, that included regular ID’s in English and Korean, made it fairly easy to spot.

The recording here (circa 1983) was made in Brantford, Ontario, Canada, using a Panasonic RF-3100 portable receiver and a long wire antenna. As a bonus, this station offered a variety of colorful QSL cards to its listeners.

Today, KBS World Radio from Seoul in the Republic of Korea continues to offer programs via shortwave in several languages including English. Transmitter power up to 250 kw is used so they should be audible in most parts of the world. “Sign on” is strikingly similar using the same interval signal with bi-lingual ID’s and opening music.

They also use some of the same frequencies, including 9570 and 15575 kHz, that they have broadcast on for decades. This recording was made using a remote SDR in Hong Kong on August 14, 2025 on 15575 kHz around 1300 hours UTC.
