Once you are up and running – please go to http://www.sdrspace.com/Version-3 and view your listing – if there is a yellow triangle, then you are not accessible outside your own firewall – attention is needed! Just because you can access it on your own LAN doesn’t mean it’s accessible via the internet!!! This is the most common area to have problems – double check your router’s port forwarding settings are correct (default port 50101 TCP).

Lots happening with KiwiSDR – there are now over 130 live 0-30MHz fully controllable SDRs scatted around the world some in really interesting locations. Using Kiwi’s around the world is like being able to go on a exotic DXpedition any time.
Here (attached graphic) is a map of the current locations, you can see the live status of online receivers here:
KiwiSDRs now include HF Fax reception natively, just select Fax in the Extension menu, select the part of the world you are interested in and the Kiwi will tune the weather fax frequency and receive the weather fax all natively (no extra software needed) – too easy!
Thank you for the update, Mark! I had no idea the KiwiSDR app had an HF Fax extension. After reading your message, I loaded a KiwiSDR session in Europe and used the Fax feature. It couldn’t have been easier. The screen grab (above) came from my first attempt.
The KiwiSDR network is truly amazing. I use it all the time–especially if there’s an important broadcast happening and I can’t easily receive it at home or while traveling. As an example, during the recent French elections, I listened to results roll in on France Inter mediumwave from a KiwiSDR in Italy. It felt like being there.
My one feature request would be that the KiwiSDR app include some form of native broadcast recording like the WebSDR at U Twente.
I would have purchased a KiwiSDR ages ago–during their Kickstarter campaign–if I only had the Internet bandwidth at home to support it. My Internet speeds are likely lower than anyone else here in the SWLing Post community. One of the compromises living in a relatively remote spot with no RFI. 🙂

I am Sylvain, from Cloud-SDR, a new company selling software to get remote access to your existing SDR receivers through the Internet.
currently supports : SDRPlay, Perseus, BladeRF and AirSpy. LimeSDR to come when received and tested.
client software is free (can be used as standard SDR receiving software with locally connected devices),
server software starts at 110 Euros, VAT may be added depending on customer location,
easy to use
From the Cloud-SDR website:
The Cloud-SDR Concept
You need a way to remotely access your existing SDR receiver? To stream your IQ samples to another remote computer over the network?
Cloud-SDR is a commercial software solution to enable real time RF data sharing or processing through the cloud.
Cloud-SDR can collect real-time IQ complex samples from an SDR hardware device connected on one machine, stream the samples to a second machine for demodulation or analysis, then send the resulting stream to third machine for storage.
Because network bandwidth is limited compared to SDR receiving bandwidth, the core concept of Cloud-SDR is to move the processing along the cloud to where it is required or possible : the DSP chain is divided in sub-tasks that are spread between computers interconnected through Internet.
Very cool, Sylvain!
I like the fact your system supports popular affordable SDRs like the SDRplay RSP & AirSpy and that you can stream your IQ samples.
SWLing Post contributor, Mark Fahey, has just announced that his new Beaglebone-powered KiwiSDR receiver is online. Mark notes:
Please try out my multi-user 0-30MHz SDR[.] The test system is operating from my monitoring station at Freemans Reach in south east Australia (near Sydney).
Freemans Reach, Australia
[…]The test system is fully self contained and self operating. The antenna (ALA1530S+) we are using is a magnetic loop with an impedance tracking amplifier designed and manufactured by Wellbrook Communications, Llanwrth Wells in Wales. The receiver and CPU is the result of the Kickstarter funded project “KiwiSDR” which was conceived and designed by John Seamons ex Pixar and Lucas Films.
[…]You can use Chrome, Microsoft Edge, Safari, Firefox – but Internet Explorer is not supported at this stage. Tune in on this URL…
This morning, at 6:00 am, I had to take a friend to the hospital for a scheduled (minor) operation.
The hospital waiting room is spartan for a projected three hour wait, but the complimentary wi-fi Internet is quite speedy. I had planned to catch up on a movie or two via Netflix, but the hospital blocks video streaming.
I just logged into my home PC and launched both the Elad FDM-S2 and WinRadio Excabur SDR applications–fortunately, I discovered that the Excalibur was hooked up to an external antenna.
Not only does TeamViewer allow me to control a software defined radio, but it actually streams the receiver audio from my PC. With my inexpensive in-ear Sony headphones, the sound isolation and audio fidelity are quite good for a compressed audio stream. Indeed, other than a one second delay in response, the user experience is nearly as good as being home.
I should note that I could also use the TeamViewer app on my iPhone, but 4G reception in the hospital is very poor and controlling an SDR from a small touch screen is less than desirable (though works in a pinch–no pun intended).
I’m currently tuned and listening to Radio Australia, Radio Mali and the Voice of Korea.
The 31 meter band seems to be wide open at this morning. At this point, I don’t think I care if my friend’s out-patient procedure takes a while longer!
Spread the radio love
