Receivers
Every capture was made through a public KiwiSDR run by a volunteer. Where we listened from is part of the sound — the fading, the noise floor, the interference are the receiver's as much as the transmitter's. These are the sites, with thanks.

The etiquette we follow
- We connect as user nil-heard, so an operator can see who is on their receiver.
- One slot per site, never the last free slot, never two sessions on one box.
- A receiver that refuses automated clients, or whose operator asks to be left alone, is never tried again.
- We publish the site location and antenna as the operator lists them publicly — never the receiver's address. Sending an audience to a volunteer's receiver is exactly what their terms ask us not to do.
- Any operator who would rather not be named here: one mail to log@nilheard.com and the location is withheld within a day.
