Kiwi SDR TDoA & HFU - Please read
« on: February 07, 2023, 0315 UTC »
I speak on behalf of many pirate radio operators and respectfully ask all members of hfunderground, new and senior, to please respect the privacy of all pirate radio operators and please do NOT post links to screen captures of the TDoA results or post the coordinates of the TDoA results from the Kiwi SDR in this forum.
I ask you to please keep this information to yourself.
Thank you.

Time Difference of Arrival (TDoA) is a method used for locating the position of a transmitter based on the differences in propagation times of signals received by multiple receivers.

If you use several Kiwi receivers it is possible to gauge where a TX is located.
