ΣSDR2 is now online!

Thanks to several very generous donors a second KiwiSDR is now online!

If the first receiver is full, it will automatically transfer you to the second one. There are now eight users slots available on this system.

Help add more user slots...

If you have the means, please consider making a donation toward the purchase of a second receiver. This will open up twice the number of user slots and you'll see fewer "Sorry, the KiwiSDR server is too busy right now" messages. Both receivers will be connected to the same antenna so they will both perform very well.

The second receiver has been funded thanks to several generous donors!

Any size donation ($1, $5, $10...) is sincerely appreciated. Please use the Paypal donate button below. If you prefer to send your donation via the mail, please email me and I will forward my mailing address to you.

Thank you!

FIXED! Antenna Degradation

Having some odd intermittent issues with the antenna. Troubleshooting shows that it might be the balun on the Off Center Fed dipole. Working toward fixing this but it may be an issue that is pushed off toward the nicer weather of the spring.   

Had a beautiful sunny day to drop the antenna today. I found both the balun and coax connector were faulty. I believe that all is back to normal again. Thanks for your patience! :)

Courtesy Request

This receiver is very popular and the user slots are often completely filled. If you are not actively listening, please close out to give others a chance to use the receiver. Your courtesy will go a long way toward allowing everyone an opportunity to listen.

Thank you for your support!

Hurricane Watch Net

Check out the Hurricane Watch Net on the following frequencies. The net is active during hurricanes that affect the US and the region:






During the summer thunderstorm season the antenna may be disconnected from the SDR to protect it. If the storm occurs late at night it will remain disconnected until the next morning. Check out this lightning map if you want to see what is going on in the area.
