[GreenKeys] period HF receivers

[Pete Lancashire]

Have not done it yet but I'm going to put one of the Teletypes in the
living room. A TU and a HF receiver, something like the Hallicrafters SX-42
with its industrial design by Henry Dreyfus since it is the living room.

Since there is pretty much zip on HF now days, build a little mW
transmitter and FSK it from something off the internet.
