The Antenna

Get lots of questions about the antenna. Here is a link to it at Palomar Engineers. It is a terrific antenna and is also great for transmitting on the ham bands.

Here is the SWR plot for it when used for transmitting:


I confirmed this plot with an antenna analyzer after it was mounted at 65 ft. high and it was very close. The antenna is about 130 feet long and is supported on both ends as well as the center.

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!

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. https://n1nte.blogspot.com/p/online-kiwisdr-receivers.html

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.
