Dr Karl

They've got retransmitters which work on some but not all of the stations.

So they'll work on the government stations and they've got their own special channel which can come across all of those.

The reason they do that is so they can come across your radio if you happen to be listening to the radio and say there's a blockage in lane, the right-hand lane or the left-hand lane.

And so the volume that they're retransmitting to you is not the same as you're getting through the air from the antenna outside, I think.

Can we have an engineer involved in this with the radio signals to tell me if I'm guessing on the right track?

That was all a guess, Dr. Annabelle.

But I've noticed the same thing myself and I've talked to people about it and I think that's the right answer, but I'm not sure.

Is that pool of yours, is it proud of the landscape?

Is it the highest point or is it in a bit of a dip where water can run across the soil and then, if there's a massive storm, overflow into the pool?

Oh, okay.

Because that sort of thing that you've described normally happens when you have a massive thunderstorm.

And the worms like to breathe air.

They are oxygen-breathing creatures.

And if the ground is flooded, they'll come to the surface and then you'll see the birds going peck, peck, peck.

But in this case, they're on the surface and then depending on the natural flow of the geometry of the ground, they'll either get washed towards or away from the pool or just totally neutral.

But you're saying there's no slope on the land that would tend to wash them downhill into your pool.

No.

Right.

So I'm guessing in that case it was just all flooded evenly and there were little currents that carried them across into the pool.

Probably not thousands, probably hundreds, but it would be a large number.
