Again... *where*  ?  It looks like a KiwiSDR. There's hundreds if not thousands of KiwiSDRs online. Which one.

Just 17946 kHz was masked. Looks like it's an aviation frequency. I blocked it most likely because I got tired of people sitting on it for hours at a time.

I removed the mask, I'll keep it removed as long as users behave  ;D
