Hopefully someone will read this and know what I'm talking about. Sometime during August or September, I was listening to 5850 khz and heard a radio show that was about pirate shortwave broadcasting. It included a recording of a pirate broadcast in New Zealand. The best guess I could make for the time of day would be sometime during 0000-0500 UTC. I'm pretty sure it wasn't World of Radio as the broadcast I heard was entirely focused on pirate radio.
If anyone recognizes which show this might be, I'd love to know more!
