I, too am hearing Sam on 5 MHZ with a strong signal in North Texas.
This is almost certainly a covert "go" signal from our government.
Could be an exercize (most likely).
It's on WWV at 5 mHz because that provides a "BFO" for cheap SW
receivers. I will note the times I hear him.
Please note those you hear.

But then why did YS operate on all the other frequencies where a supposed "BFO"
would not be provided in his first incarnation?

I somehow doubt that it's a "go" signal at all.

I for one will be checking the commodity markets this coming week to see what
tin foil is going for. It may be time to invest!
