[GreenKeys] Polar keying relays.

Hey.Your work bench looks like my workbench.

That unit reminds me of the K6USA MARS station setup in the late 50s. 
Was there on a visit with my father. The speaker was emitting 
twittle, the TTY machine was running continuously, the center zero 
meter was bumping around and the machine was magically printing out 
the news. I was hooked.
