K1RA SDR online

As of June 2022 all K1RA SDRs were offline due to wind and tree damage after a storm that brought 80 mph straight line winds through my Warrenton, VA QTH.  All my wire antennas were destroyed. See news article about other damage in town.  I’ve managed to get something temporary running using a 50′ random wire.  Check out latest info.

My KiwiSDRs are back on the air! Back during early 2016 I invested in a Kickstater project called KiwiSDR. This project was the development of an add-on cape to a small form factor, Linux computer known and the Beaglebone Black. This hardware allows for up to 4 simultaneous online users to tune in any part of the HF radio spectrum from 0-30 MHz, using several different modes, as well as providing visual feedback of signals and some demodulation of digital modes. The software employed in known as OpenWebRX and was originally written by HA7LIM (now maintained by Jakob DD5JFK here), but was modified by KiwiSDR founder KF6VO to support some specific features of the new hardware. If there is an available slot on my SDR, located in Warrenton, VA grid FM18cr, you may tune in and listen for yourself by clicking on this link or picture below. If it is full you may try one of the many other KiwiSDR’s found listed at the KiwiSDR Receiver List. There is also an OpenWebRX Receiver List.

    Hi Andy!

    Hope you’ve been well. I was just cruising around QRZ a few minutes ago and thought, “I wonder what Andy is up to these days.” So I went to your site and this post about KiwiSDR caught my eye. Very cool. I played around with it for quite a while and appreciate your making it available. Just last night I was messing with one of the NooElec SDRs and an upconverter that you recommended several years ago. I’m finally easing back into the hobby now that I’ve had a chance to unpack most of my junk here in Forest, VA. Hope to catch up with you sometime soon.

    Take care,

    I like your SDR, Andy. The low noise signal is so cool!
    Thank you for making it available.

    I was just surfing around your site here. I obviously didn’t look at it very hard a few weeks ago. You’ve got all sorts of cool stuff here!! I’ll have to search around and find the help files for the KiwiSDR…

  4. Hi Andy, I just tried to access your SDR and could not connect. I was wondering if it is still a available. I have used it in the past month and really did enjoy it.
    Thanks for all your effort.

      I took a close lightening hit last week and lots much of my online SDR systems. I’m trying to diagnose what if anything is fixable.

    Hello from Luzern, Switzerland, when I was living in Brazil I was always listening HF on your K1RA SDR. The Reception was always great.

    Is this SDR definitely QRT, or the URL Address has changed ??

    Best Regards & 73s from Nick,

    Very cool resource! I’m finally getting my uBITx on the air and I just used your rx to copy my WSPR signal on 40m. I’m impressed with the capabilities on the receivers on that SDR.

    Thank you, I am very new to this and exploring SDR . Think I have found a new hobby. I am not new to radio, I was a radioman in the U.S Coast Guard late 1970s, then again a long time away from radios. It was exciting to hear and copy some CW , little rusty but fun.
