Hi Gary, LF!
TNX to all for the details and participation in identification.
I thought about an NDB, but signal was so very long 1 minute.
Is't real to be an NDB ID.
Some time he was like a carrier on the screen.

Do you tried to rx today or yesterday?
That signal is absent today on the grabber.
