Tecsun Radios Australia has set up a Software defined radio (receiver) in Araluen, a small rural community in NSW, Australia. It’s a quiet location for radio “noise”, far away from high density population and the accompanying RF noise generated.
You can listen to the Tecsun Radios Australia SDR here.
The SDR itself is called a “KiwiSDR” and is a commercially available unit, costing around $500. The Kiwi SDR compared to others has 2 advantages: (1) it allows the user to observe the entire shortwave spectrum in one screen, and (2) it can easily be connected to the internet to allow remote operation.
Other SDRs only receive a narrow portion of the radio spectrum, and require extra equipment to connect to the internet.
With the Kiwi SDR, it is easy to remotely identify that a signal exists from the “waterfall” display and then accurately tune and receive it.
The SDR is connected to two separate trapped HF vertical antennas. Each antenna is fed via common mode chokes ,one at the antenna end, and one at the equipment end of each cable run. These 2 antennas are then fed to an HF signal combiner. This provides some degree of antenna redundancy. The HF combiner feeds a 1:1 50 ohm transformer to isolate the KiwiSDR power supply ground from the antenna ground.
The antennas have been located as far away from man made noise sources as possible, and are fed with 75 ohm quad shield cable. Careful attention has also been paid to the grounding of the antenna.
Because the location is remote and in a bushfire affected area, mains power is supplemented by battery backup. The 5 volt power supply required by the KiwiSDR is a linear power supply that has a built in switching delay of 0.5 seconds, to ensure stable reset after power failure. We have been unable to surce a UPS with low RFI footprint for this application.
Connectivity to the www is achieved via a Skylink Ka band satellite link.
The Kiwi SDR can be used to receive AM, AM Narrow, USB, LSB, weatherfax, CW (Morse Code) and DRM signals.

You can listen to the Tecsun Radios Australia SDR here.
Or, simply logon to the SDR (go to http://kiwisdr.com/public/ for a worldwide list), select an SDR located close to the transmission source you’d like to listen to, select the appropriate mode and the desired frequency.

This week Federal Labor has announced that if elected to Government next year it will provide $2 million in funding for the ABC, specifically to bring back shortwave radio services across some of Australia’s most remote areas.

The Tecsun S-8800 has been a long time coming to the Australian market so we’re very excited that Silicon Chip Magazine has featured this great new addition to our range of radios in their most recent July 2017 magazine!
The Tecsun S-8800 review is on Page 57 of the July 2017 issue of Silicon Chip Magazine!
Here are some of the great things they had to say about the P-8800.
“If you live in, or go “bush” and want a radio that will let you keep listening where other radios have given up, or if you’re a city resident who wants to give DX listening a go, try the Tecsun S-8800.”
– Silicon Chip Magazine
“The S-8800 is right up there, even exceeding many higher-priced sets in its ability to not only resolve distant stations but to maintain them at an enjoyable level.”
– Silicon Chip Magazine
“The shortwave section covers just above the broadcast band (1.711MHz) through to almost 30MHz (actually 29.999MHz and with its single sideband plus AM reception, along with fine tuning, you’ll be pulling in stations that you didn’t know existed!”
– Silicon Chip Magazine
And the Silicon Chip team aren’t the only ones excited about this great new addition to the Tecsun family of radios. Here you can read Garry Cratt’s full review here, and watch the video demonstration!
“Although the frequency range is stated as 520-1620kHz (when the receiver is set to 9kHz spacing), it can be extended by setting the receiver to 10kHz spacing and then it will be possible to tune 520-1710kHz. By using slow tuning steps (1kHz), and station can be tuned.”
– Radio expert Garry Cratt (VK2YBX)
The S-8800 was featured and reviewed in Silicon Chip Magazine alongside the new Tecsun D-008 DAB+ Digital Radio!
The Tecsun S-8800 High Performance AM/FM Radio has been designed to provide maximum performance on the AM (MW) bands, allowing listeners to receive fringe AM radio stations with unmatched audio clarity.
The Tecsun S-8800 is the only radio in the Tecsun range to provide an infrared remote control in the kit. An absolute luxury for the user as all functions are able to be controlled by the remote. The remote uses standard AAA batteries to make using the remote hassle-free and cheap when it needs recharging.
The Tecsun S-8800 is available and in stock now, right in time for Father’s Day! Find out what else is new for Father’s Day!
