Improved Interface for Smartphone Use

Some experimental code has been added to all four KiwiSDR receivers that should allow for a better experience while using a smartphone. I welcome any feedback on this that you might have.

If your favorite KiwiSDR is full, you can listen to what other people are listening to and put yourself in a queue. Read more here:,79143.0.html

Intermittent Antenna Issue Fixed

Over the last week or two I noticed that signals on the KiwiSDRs occasionally dropped 10-20 dB or more and then would go back up to normal full strength. I dropped the antenna today and noticed that one of the wing nuts on the balun that connected one of leg of the dipole to it was loose. (We've had several days of strong winds over the last couple of weeks.) Been listening to it for about an hour now and the issue seems to be resolved. Enjoy listening!

All Receivers have Full Waterfall Now

Updated  ΣSDR4  to four waterfall channels instead of two waterfall and six audio only channels. If you have a legitimate need to listen for extended period of times, feel free to go directly to this receiver.  See for more information.

Receiver Timeouts Increased

For your wintertime listening pleasure, the session timeouts and maximum daily times have been increased. On receivers 1, 2, and 3 there is a 3 hour per session timeout and a 10 hour per day maximum per person. On receiver 4 there is a 6 hours per session timeout and a 18 hour per day maximum per person. Timeouts are instituted to make sure that inactive sessions don't tie up a receiver and prevent others from using it. If your session times out you can reconnect up to the daily maximum.
