The "6 GHz" band is an unlicensed frequency for very-low power (VLP) devices in the US.
Specific bands are: "U–NII–5 (5.925–6.425 MHz) and U–NII–7 (6.525–6.875 MHz)".
VLP is defined as those devices which "operate at up to −5 dBm/MHz power spectral density (PSD) and 14 dBm EIRP".

- mNovak 2y ago14dBm EIRP is extremely low power for a radar however. Off the bat the author is using 1W (30dBm) PA, and you could readily get another 20dB from a moderate sized antenna (e.g. repurpose a scrap DirecTV dish). Unless you're next to a base, it's the FCC that will come knocking long before the military.
