[GreenKeys] RTTY (over the air) to KSR33

[Pete Lancashire]

Before everything got pushed out into a corner My demo was a source of text
-> FSK modulator -> 1 Watt homemade SW Transmitter -> attenuator -> coax to
living room -> Hammarlund SP 600 JX21  -> converter of the month ->
Teletype.

When the transmitter died one day from getting soaked with the water from
the soldering iron sponge bottle, the same day I was going to show some
friends the setup I used an HP synthesizer that could do FSK.
