Little does he know that the magical black box spawns radio waves no more!
The collector current is zero due to a burnt out fuse. Only miliwatts from
the driver make their way to the antenna. Only the nearest stations decode
it.
But look: Christmas is a magical time and anything can happen. The digital
mode is sent by a closed-source application. There is no formal
documentation from the author and we can't look at the source. Since we
really don't know what it does, the author implemented yet another trick
to show long range decodes. The transmitting station's application
covertly sends this data to the author's server. Randomly, with very low
probability the author's server commands the receivng station's programs
to decode the station even if nothing is being received.
"Look! I'm being decoded in Australia! The ultimate MF DX!" screams the
digital operator, seeing his christmas wish come true.

PS. the receiver didn't work either, but we have good propagation on the
internet today
