All I could get was a very slight carrier , but thats a short antenna so
if I had something longer like a Windom I expect a much better signal ,
I doubt it's a low power tx

Heard it in East Brighton (Vic) on Saturday night, about ten minutes after
your logged time. Couldn't hear it from inside the house - had to use car
radio with antenna extended. Audio not clear - sounded as though there
was (power line?) hum superimposed on it.

Haven't heard the station since.

Maybe they used a powerline as an antenna?

BUSTED!! and no one listens to AM hey? Was it the postings on FB that
got them found? Who knows. But it's fuel to my fire when I promote
doing it legit on nas freqs or SW Dom etc! Better than getting
everything confiscated!

Now that is a spooky but plausible suggestion. DOn't put stuff on
Facebook that you wouldn't tell you mother personally. And that goes
for pirate radio as well. If you want to sail under the radar, then
stay of the places where the commentariat hang out.

[Timbo]

Yep going public isn't the best thing to do and of course
if you're going to tell the world ,then......! Always the risk of a
bust I suppose!
