I used to work in the Jindalee OTHR facility back in the woodpecker days. I've memories of sitting in the control room, and being given a tour of the airwaves by one of the senior techs, who was also a ham. The tour included listening on on the various HF radars that we could find, including the woodpecker, discussing each system as we went. By the nature of the project, a lot of the technical people had an interest in ham radio, so they looked out for the ham bands. The tech who gave me the tour used to occasionally have a bit of fun by plugging his ham rig into the main transmitter (lots of power, with beamforming).
The other cool bit of technology was the "frequency management system", which was a mini HF radar, used to map the ionosphere in real time. It was fascinating to watch the dynamics of the various ionospheric layers on the screens.
Just like that superbowl ring.
edit: forgot to say it's the first time I heard of the story, and it is pretty 'wtf' to me.
Also here are some recent 2015 transmissions:
