Shower powered radio

(Source: The Telegraph)

The man who helped turn the Wind-Up Radio into a global success in the 1990s has invented a radio that is powered by the motion of water flowing into a shower.

The H20 water-powered radio clips onto the water pipe that runs up to a shower head. Using micro turbine technology, the radio is powered by the water pressure running up a pipe.

[…]Tango hopes that the waterproof radio will enjoy the same success as the Wind-Up Radio. The H20 was invented by Vivian Black, a former director of Freeplay Energy Group, which helped turn Trevor Baylis’s Wind-UP Radio into a commercial success in the 1990s.

While shower-powered radio is certainly an inventive use of flowing water, I seriously doubt the technology will enjoy the overwhealming success of wind-up radio. Wind-up or crank-powered energy generation can be used pretty much anytime, anywhere.  It’s also a very appropriate technology for the developing world.

In situations where one lacks access to power, there will most likely be a lack of water. However, for those of us who love listening to radio in the shower, this may be worth the investment. (I do wonder if how “green” this product will be if it keeps you in the shower a bit longer.)

Tecsun PL-398BT, PL-398MP and Tecsun PL-505 now available for purchase via sellers on eBay

The new Tecsun PL-398BT features Bluetooth technology, which allows for remote radio listening on computers and mobile phones with Bluetooth capabilities.

In August, we announced that Tecsun was coming out with several new models this year. Three of them–the Tecsun PL-505, Tecsun PL-398MP and PL-398BT–are now available for purchase on eBay. See links below.

The PL-398BT is the most innovative portable shortwave radio I’ve seen hit the market this year, as it will allow you to stream broadcasts from your radio to any Bluetooth-enabled device. I certainly hope it performs as well as previous Tecsun models. The sister to the PL-398BT is the Tecsun PL-398MP, which has an MP3 player (unfortunately, not a recorder, as we had hoped) that runs from a built-in SD card slot.

Heathkit is back in business

Great news for kit builders! Legendary company Heathkit has started manufacturing kits again. Though their first line-up of products do not include radios, they are planning to cater to the amateur radio community as soon as next year.

I would like to believe that the popularity of the Maker community has given Heathkit the ability to re-enter the growing kit building market (it has certainly given Radio Shack reason to continue carrying components).

Here is an announcement from Heathkit’s website:

Thank you for your overwhelming response to our announcement that Heathkit is back into the Do-it-Yourself kits business. We received many great suggestions for kits you would like to build.

We will be releasing Garage Parking Assistant kit (GPA-100) in late September and soon after the Wireless Swimming Pool Monitor kit will be available.

Based on your input, we are looking at developing amateur radio kits. Our goal is to have kits available by the end of year.

Please keep your suggestions coming so that we can continue to bring you interesting, unique Heathkit products.

Now is the time to let Heathkit know you that you want shortwave and amateur radio kits!

Tecsun about to update their product line? Photos surface of the new Tecsun PL-505 and Tecsun PL-398BT (Bluetooth)

The new Tecsun PL-398BT will feature Bluetooth technology, which should allow for remote radio listening on computers, mobile phones and other devices with Bluetooth capabilities.

This week, I noticed a post on the excellent Herculodge blog that Tecsun is about to update their product line, placing an even stronger emphasis on quality control and offering up innovative features like Bluetooth technologies on their new PL-398BT. Some of the Herculodge’s information came from one of their own sources and a discussion thread from Tecsun’s user group that was started by a member who had recently taken a tour of Tecsun’s Shanghai service center.

This is very exciting news indeed as I have become quite fond of the Tecsun product line. Tecsun portable radios seem to have excellent quality control (especially when compared to the likes of Degen and Kaito, for example) and offer innovative features like an adjustable IF bandwidth and ETM (Easy Tuning Mode)–features not typically associated with shortwave portables.

The Tecsun PL-505 looks to be an improved version of the popular Tecsun PL-606.

I would have to assume that these radios will primarily be available through Honk Kong distributors on eBay. This year, Kaito USA became North America’s only authorized distributor of Tecsun radios–meaning, they can offer a manufacturer’s warranty, something Hong Kong distributors cannot. However, reports are that Kaito USA’s Tecsun radio stock may not be as updated as the versions sold by Tecsun distributors on eBay. In general, feedback from eBay purchasers has been very positive as eBay sellers offer their own guarantee and many check each radio before it is shipped (hence, your box may look like it has already been opened).   Before purchasing any radio on eBay, make sure you check each seller’s user feedback points.

If history is an indicator, the Tecsun PL-505 and Tecsun PL-398BT will first be available to purchase on eBay. I have provided links below to automate your search–please note that until these products are available, don’t expect to see any results.



I have added the Tecsun PL-505 and the Tecsun PL-398BT to the Shortwave Radio Index (SWRI) and will make every attempt to update product specifications and reviews of these two products there.

Please contact me if you have any new information or announcements to share.

Silicon Labs ships one billionth DSP radio chip

Silicon Labs, the chip manufacturer behind some of the best portable shortwave radios in the market (including Tecsun and Grundig) has sold its one billionth DSP radio chip. Silicon Labs has been one of the best things to happen to the portable shortwave market this century. Their DSP chips lower the production cost of radios and enhance the performance with Digital Signal Processing.

I eagerly await the new Tecsun R-2010–an analog radio with the Silicon Labs’ Si483x DSP chip. Not only will it enhance the performance of this basic analog radio, but it should also decrease production costs by as much as 80%!

Here is the full SiLabs press release:

Industry’s First CMOS “Radio-on-a-Chip” ICs Widely Adopted in Leading Consumer Electronics and Automotive Designs

Reaching a major milestone in the broadcast audio market, Silicon Laboratories Inc [2]. (NASDAQ: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced that it has shipped its one billionth broadcast radio IC. Silicon Labs’ digital CMOS broadcast radios are widely used in handsets, portable media players (PMPs), personal navigation devices (PNDs), automotive infotainment systems, tabletop and bedside radios, portable radios, boom boxes and numerous other consumer electronics products.

Silicon Labs introduced the industry’s first single-chip FM receiver in 2005. As the industry’s smallest, highest performance and most integrated FM broadcast radio IC, the Si4700 [3] IC redefined how FM tuners were designed into consumer electronics products.

The highly integrated Si4700 revolutionized broadcast radio designs by offering exceptional, highly flexible performance, while simultaneously reducing component count by more than 90 percent and board space by more than 60 percent.

Over the past six years, Silicon Labs has rapidly expanded its broadcast audio portfolio [4] to more than 40 distinct products including FM radio receivers, FM radio transmitters/transceivers, AM/FM receivers, shortwave and weather band receivers, RDS data receivers and automotive radio receivers. These products are now the broadcast radio ICs of choice for many leading consumer electronics brands.

“Silicon Labs delivered the industry’s first monolithic all-CMOS FM receiver, providing breakthrough cost, size, integration and performance for broadcast receiver applications in handsets, navigation devices, media players and consumer electronics,” said Jag Bolaria, a senior analyst at The Linley Group. “The company has continued to drive market innovation in CMOS FM transmitters and multi-band AM/FM/SW and weather-band receivers, all widely adopted in the consumer electronics, portable and automotive markets.”

Silicon Labs’ broadcast radio ICs leverage the company’s patented low-IF digital architecture, which enables the highest level of selectivity and sensitivity performance for radios, resulting in reduced interference and superior reception. In addition, Silicon Labs broadcast receivers incorporate advanced audio processing technology that delivers sound quality that is unmatched by other competing radio receiver ICs.

“Silicon Labs thrives on pioneering new ways to solve difficult system design challenges with mixed-signal technology,” said Diwakar Vishakhadatta, general manager of Silicon Labs’ broadcast audio products. “Our single-chip FM, AM/FM receiver and transceiver families are a case in point. These products have helped our customers reduce the cost and complexity of their designs while enabling more features and functionality to help them differentiate their products in the marketplace. We continue to invest and innovate around our low-IF digital architecture to remain a strategic supplier of broadcast radio technology to the industry.”

Silicon Labs has approximately 100 issued and pending worldwide patent applications in audio technologies for its AM and FM related products.
