"Boatanchor" is amateur radio slang for heavy old tube radio equipment. Originally derogatory, the term is now used affectionately. Seeing an old set working like new after careful repair, cleaning, and alignment gives one great satisfaction.



"Forget the net.
Switch on the set.
Warm it up slow and go.
Light the tubes, bask in the glow.
Surf shortwaves on your old radio."
