I've been using http://ve3sun.com/KiwiSDR/index.php along with http://www.short-wave.info/index.php , to locate KiwiSDR that have the highest propagation probability for receiving a transmitter from a known location.  VE3SUN has made this quite convenient and almost intuitive to use. I have not read much about it on this forum and believe it should be well known by all KiwiSDR users. 

My most recent use of this service is shown on the attached screenshot. This excellent KiwiSDR is way down the list on sdr.hu and I would not have found it without using the propagation chart generated by VE3SUN. I was able to receive this DRM station with nearly flawless reception for a considerable time before I needed to turn it off for other tasks.

Thank you VE3SUN for making this excellent website.

    Listening to DRM radio for Radio New Zealand International and using the online tools to zero in on a KiwiSDR capable of good reception. The area of best reception was generally failing to provide a signal that would demodulate. As I inspected the DRM signal, I could see interfering signals within the bandwidth. Apparently these signals are local to the New Zealand / Australia area.  As I had good reception from Hawaii yesterday on a higher frequency, I decided to see what reception was available at NH6XO ( http://72.235.216.139:8073/?f=7285.0iqz10 ), and as it happened, that was a good station to demodulate. Even though the signal strength was less, the interfering signals were not detected and having a clean signal, I was able to continuously demodulate the signal. This receiver does timeout after 16 minutes, but a screen refresh brings it back without a password. So I should bug NH6XO for a timeout password, Hi Hi.

    At 1757UTC the DRM station stopped transmitting. So the next frequency down was 9780KHz. Changing to this frequency on the same KiwiSDR ( NH6XO ) and the story continued. Very cool.

    So this has been my KiwiSDR DX logic for awhile now. I wonder if anyone else is using the online tools from VE3SUN?

    Be sure to send a reception report to www.rnzi.com as it says in the DRM info window. I'm sure a lot of these broadcasters sending DRM wonder if they are wasting their time doing so.

    I made a video of receiving RNZI from the KiwiSDR at NH6XO today. It is intended as instruction in DRM and the VE3SUN website.

    Took another look at RNZI at NH6XO this morning and sure enough, it is still being received there on the RNZI DRM schedules. Must be a pipeline to that KiwiSDR. I have not found another KiwiSDR that consistently receives RNZI this well. Made another video.

    Shortwave.info isn't keeping up with the schedule changes of RNZI, so it is a good idea to keep track at the above website for current RNZI broadcasts.

    Thanks for the video and comments, Ron.

    I have been away for a few weeks, so just catching up on my Kiwi reading.
