Ivan compares the AirSpy HF+ to the KiwiSDR

Many thanks to SWLing Post contributor, Ivan (NO2CW), who writes:

I have been running a public Kiwisdr server for a while and yesterday decided to plug in the new Airspy HF + into the same antenna for a side to side comparison. The antenna is an 80m dipole and the test was done during local afternoon, around 3 PM. I did not use any of the many new noise reduction features that are incorporated into both SDR Console 3 and the SDR web server. The 11 minute video is located here:

When I have the time I will run a similar test in nighttime conditions and also test the Airspy HF+ against a few other radios sitting on my desk.

Thank you for sharing this, Ivan!

KiwiSDR network updates include native HF FAX

Many thanks to SWLing Post contributor, Mark Fahey, who writes:

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:

and as a list of receivers here:

http://kiwisdr.com/public/

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!

Lots more great things happening.

Here is the latest news…

Cheers,

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.

Many thanks for the update, Mark!

Would you like to host your own KiwiSDR?

The whole system only costs $299 US. The KiwiSDR site has a list of distributors around the world.

Amazon has units in stock at $299 US shipped.

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. 🙂

Mark’s multi-user SDR is now online

mark-fahey-beagle-kiwi-sdr

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…

Many thanks for sharing your KiwiSDR, Mark! Though demand has been quite high, I have managed to claim one of the four user seats on Mark’s SDR and “listen like a local.”

Mark: you’ve done a great job making a proper listening post for your remote listeners. The KiwiSDR/Wellbrook ALA1530S+ combo is performing admirably!

Check out the new web-based KiwiSDR in New Zealand

Kiwi-SDR-1

Many thanks to SWLing Post contributor, Andrea Borgnino, who shares a link to a new web SDR in New Zealand: The KiwiSDR installation.

Andrea posted the following on Twitter:

I agree with Andrea: this WebSDR has an amazing display and user interface. It even includes both a spectrum and full-color waterfall.

I’ve enjoyed tuning around the mediumwave band in New Zealand this morning. My Internet connection is terribly slow (and unreliable) but I was still able to view the full display while streaming audio with only a few hiccups.  With a moderately robust Internet connection, I believe you’ll be pleased with the KiwiSDR.

Many thanks, Andrea, for the tip!
